Mechanical and Manufacturing Engineering 20 Chemical Engineering Chemical Engineering TEAM 1 - BOOTH 101 TEAM 4 - BOOTH 104 Design of a Natural Gas Plant Treatment of Heavy Oil Stripper Bottoms Lukas Smith, Christopher Sardinha, Andrew Beaule Kevin Lam, Beverly Sia, Duy Nguyen, Erica Sugianto This project involves the design of a sweet natural gas processing plant with a capacity of 500 million standard cubic feet per day. The feed stream is wet natural gas with a significant fraction of heavier hydrocarbons. The gas is first dehydrated using a triethylene glycol liquid absorption unit while the heavier hydrocarbon fractions are removed using a refrigerated lean oil process. The liquefied gas is then separated into propane, butane, pentane, and natural gas liquid products. A vapour recovery unit recaptures hydrocarbon vapours venting from a water storage tank. A VMGSim computer model was formulated to complete the material and energy balances. A preliminary economic evaluation suggests that the project may not be feasible, with a return on investment of only 1.8% and a payout period of 45 years. A settling tank process has been designed to treat Shell Canada’s heavy sour crude oil, known as Albian Heavy Synthetic. The process involves a heavy oil sedimentation treatment unit and a gas treatment unit. The sedimentation unit utilizes settling tanks to remove sediments from the heavy oil, allowing the product to be sold at a higher market price. The gas treatment unit employs a standard amine gas sweetening process (absorber plus regenerator) to remove hydrogen sulphide from the heavy oil offgas. The sweetened gas is separated into butane and heavier hydrocarbons, which represent additional saleable products. The total capital investment required is $23.4 million. The estimated expected rate of return is 2108%, the discounted cash flow rate of return is 2108%, and the net present worth is $3.7 billion. The expect payout period is 0.04 years. TEAM 2 - BOOTH 102 TEAM 5 - BOOTH 105 Propane Dehydrogenation Plant Manufacture of Phenol and Acetone Joran Kosterman, Nicole Hawkins, Richard Kaldenhoven, Dylan Bouchard With propane supply and propylene demand on the rise in recent years, an opportunity existed for the development of a propane dehydrogenation plant in Alberta. Propylene is a valuable commodity that is used in the manufacturing of acetone, phenol, isopropanol, acrylonitrile and, most commonly, polypropylene. The Oleflex process was selected for the design of the plant because it is continuous and has more industrial applications than any other dehydrogenation technology. The plant was modelled using VMGSim simulation software and is expected to meet the design production rate of 500,000 metric tonnes per year of polymer-grade propylene. Based on a $900 million capital forecast and a project life of 25 years, it was estimated that the project will result in a 24% return on investment and a payout period of 3.5 years. Amanda Chan, Jessica Weber, Kimberly Bowal, Katelyn Knudsgaard Phenol is a vital precursor in the production of important industrial compounds such as epoxy and phenolic resins, polycarbonates, and nylon-6. Global phenol demand is projected to exceed 11.5 metric tonnes per year (MT/y) by 2020. This project investigates the feasibility of establishing a phenol production plant in Alberta. The ‘cumene process’ is a good design due to its ability to make acetone as a by-product, its high overall yield, and its relatively low energy costs. The proposed facility will produce over 54,000 MT/y of 99.9% phenol and 34,000 MT/y of 99.5% acetone. The project is expected to generate a return on interest of 47.3%, a discounted cash flow rate of return of 49.9%, a net present worth of over $68M, and a payout period of 1.49 years. TEAM 6 - BOOTH 106 TEAM 3 - BOOTH 103 Mixed Feed Gasification Jeffrey Kent, Karen Park, Patrick Petanca The objective of this project is to design a gasification plant capable of converting 10 tonne/hr of feedstock, comprising biomass and petcoke, into syngas. The syngas are combusted and sent through a turbine to generate electricity. A plant location in Fort McMurray was chosen due to a demand for electricity and availability of feedstock in the area. A preliminary economic analysis produced a payout period of 6.24 years and rate of return of 14.4%. After evaluating the feasibility of various gasifiers, it was determined that the characteristics of a dual circulating fluidized bed gasifier would most effectively meet the needs of the client. Fluidized bed gasifiers demand a moderate amount of steam and oxygen, have high heat transfer rates, uniform temperature profiles, and are able to gasify a variety of feed stocks. Cleaning up Oil Sands Tailing Ponds – Hydrocarbon Recovery and Water Recycling Victoria Gibson, Odeza Bactin, Scarlett Su, Mariko Dela Rosa This design project explores the feasibility of establishing a plant that would recover hydrocarbons and recycle water from Mature Fine Tailings (MFTs). The proposed process consists of four main blocks: a clay and hydrocarbon separation unit, a thickener, a fine particle separator, and a dewatering unit for sludge removal. It is intended to be incorporated into the current bitumen extraction facility. A detailed design of the mixing tank, the froth flotation column, and the rapid depth filtration unit is underway and will be completed by April 15, 2015. A preliminary economic analysis suggests that the project is feasible as it generates $11,318,000/year in total profits, the payout period is 11 years, and the rate of return is 6.5%. Net present worth is currently negative, but this reflects low oil prices; when prices recover the aforementioned financial metrics will improve. TEAM 7 - BOOTH 107 Small Scale Nitrogen Removal from Natural Gas Luke Myhre, Karl Bauer, Matt Syp, Mariana Murillo The goal of this project is to design a small scale natural gas plant capable of removing nitrogen, acid gas, and water from its inlet feedstream. This feed 2015 Capstone Design Fair 4 Chemical Engineering consists of 5 million standard cubic feet per day of natural gas from the Provost gas field. It contains high nitrogen concentrations with carbon dioxide and hydrogen sulfide contaminants. Gas processing will yield three sales streams: natural gas liquids, pipeline sales gas and carbon dioxide liquid. The process involves two stages: pre-treatment and nitrogen removal. Pre-treatment uses conventional ethylene glycol dehydration and amine sweetening; physical solvent absorption will achieve the degree of nitrogen removal from the produced gas to ensure that it meets pipeline specifications regarding the hydrocarbon dew point and gas heating value. A yearly revenue of $9.43M implies a payout period of 3.64 years, with a discounted cash flow rate of return of 27.3%. TEAM 8 - BOOTH 108 Removal of H2S and Mercaptans from SAGDProduced Gas Willis Cheung, Jonathan Wong, Michael Leung, Joshua West Many oil and gas processes involve sweetening, i.e. removal of sulphur compounds. In this project, a plant was designed to sweeten gas produced from Cenovus’ Foster Creek SAGD operation. After sweetening, 9 million standard cubic feet per day of produced gas will be burned for steam generation. The feed gas contains 3% hydrogen sulphide and 1000 parts per million of methyl mercaptan. The plant must recover 11 tonnes per day of sulphur – equivalent to 96.5% of the feed stream sulphur. The proposed design was based on the biological Thiopaq process; the sulphur produced is not of commercial grade and will therefore be disposed of in a landfill. Additional feedstocks required are sodium hydroxide, water, and nutrients for the bacteria. The discounted cash flow rate of return for this project is 17.7% with a projected payout period of 3.7 years. TEAM 9 - BOOTH 109 Converting Alberta Oil Sands Deposits into ‘Pipelineable Bitumen’ Keith Lee, John Guo, Ryan Liu Mixing light-end hydrocarbons with bitumen to produce diluted bitumen (‘dilbit’) is a widely-used technique to reduce bitumen density so that it is suitable for pipeline transport. This method requires approximately 30% of the transport capacity to be the diluent. Purchasing and transporting this diluent to/from various Alberta SAGD operations is a major cost. An alternative approach involves partial upgrading. This process gets the bitumen to pipeline specifications but has not been sufficiently developed for commercial application. This design project considers the partial upgrading of bitumen extracted from a 70,000 barrel per day SAGD facility. The net present value estimated for this project was $553M with an internal rate of return of 17%. The key technical breakthrough involved redesign of the solvent deasphalting unit to increase the yield of deasphalted oil by 4% without violating product specifications. 2015 Capstone Design Fair TEAM 10 - BOOTH 110 Dimethyl Ether Production from Methanol Ahmed Moussa, Brayden Kooistra, Justin Henke, Robert Palmer Significant advances in energy markets worldwide and regulatory developments are driving interest in the potential of dimethyl ether (DME) as a renewable and extremely low emission fuel. Over the last two decades, several international initiatives have led to the advancement of the DME business, primarily in Asia. The goal of this design project was the development of a DME production facility to produce 50,000 metric tonnes of 99.5 weight percent DME per year from crude methanol (which contains water, ethanol, acetone, and other impurities). Computer simulation confirmed that purifying crude methanol, reacting the purified product over a zeolite catalyst, then separating DME via conventional distillation, is a feasible process. At current prices, the project yields a net present value of $16.7M, discounted cash flow rate of return of 21%, return on investment of 16%, and a payback period of 6.0 years. TEAM 11 - BOOTH 111 Manufacture of Pipeline Quality Crude from SAGD Extracted Bitumen Aaron Baskerville-Bridges, Justin Woods, Julian Mulia, Robert Pryde The facility to be designed has an inlet feed capacity 250,000 barrels per day of Western Canadian Select (WCS) crude blend purchased from the Husky terminal near Hardisty, Alberta. Diluent must first be recovered from the WCS then recycled to Alberta heavy oil producers. Instead of using diluent to further transport the bitumen residue, it will be partially upgraded to meet pipeline specifications. The technology chosen to accomplish this was ‘methanoconversion’. It is currently being developed at the University of Calgary and differs from conventional upgrading processes in that the upgrading reactant is natural gas rather than hydrogen. Use of natural gas as an upgrading reactant eliminates the need for expensive steam-methane reformers, reducing plant cost. Preliminary economic indicators are favourable and include internal rates of return of 41% and 29%, based on 2014 and 2015 (forecast) oil prices, respectively. TEAM 12 - BOOTH 112 Value-Added Products from Light Alkanes Arathi Haridas, Eric Lim, Mahfam Vakili Mafakheri The recent large-scale “shale revolution” in North America has greatly increased natural gas production, further reducing its price. Fortunately, the liquid-rich component of natural gas, Natural Gas Liquids (NGLs), can be further processed into more profitable products, such as ethylene and propylene. This project considers the design of a facility which can produce 350,000 tonnes per year of value-added products given a mixed feedstock of ethane, propane and n-butane. Product streams include ethylene, propylene, 1-butene and 1,3-butadiene. Steam cracking was chosen because of its high selectivity and ability to handle mixed feeds. An economic feasibility study was carried out for the proposed facility; calculations show that the project will be earning $19.55M in after-tax profits with a rate of return of 15.1%. 5 Chemical Engineering TEAM 13 - BOOTH 113 Design of a Scaled-Up Influenza Vaccine Production System using Mammalian Cells Daniel Morley, Rutvik Patel, Trevor Paffrath, Jessica Withell Seasonal flu is a respiratory illness that is caused by influenza viruses. The best protection against this contagious disease is a flu vaccine. Vaccines typically contain either an infectious agent (e.g. a virus) that has been weakened or killed. In the case of influenza, the viruses that cause the flu change annually, consequently, new vaccines are required each year. Currently, the most common method of producing influenza vaccine is in chicken eggs. However, the eggs themselves may contain infectious agents that render them unusable. In the event of a global pandemic, current production methods will not be able to provide a sufficient number of doses. Mammalian cells can also be used to make influenza vaccines in bioreactors. In this work, an influenza vaccine production process was designed using a mammalian cell type to generate 250 million doses annually. TEAM 14 - BOOTH 114 Design of a 200 MMSCFD Hydrogen Plant Lama Ayoub, Nigel Cox, Parul Wadodkar, Rohit Dhawan The demand for hydrogen is increasing due to its use in hydrocracking, desulfurization, and ammonia and methanol production. The objective of this project is to design a 200 Million Standard Cubic Feet per Day (MMSCFD) hydrogen plant. The plant is based on a steam reforming process using a highly endothermic reaction of natural gas and steam to produce syngas. Based on results obtained via process simulation and short-cut methods, a preliminary economic evaluation was performed. It is estimated that the project will have a capital cost of $835M, return on investment of 14.1%, a discounted cash flow rate of return of 12.8%, a net present worth of $42M, and a payout period of 6.2 years. Sensitivity analysis revealed that the greatest impact on economics is the sale price of hydrogen 2015 Capstone Design Fair 6 Civil Engineering Civil Engineering TEAM 1 - BOOTH 201 Camp Borealis Carley Algeo, Christine Lieu, Colby Humphry, Gabe Goral, Jessica Dumont, John Roxas, Jordan Heck, Justin Wong, Kate Kirkland, Marianne Stevenson, Patrick Gill, Steve Cheng As oil projects move into remote locations in Northern Alberta, companies like Cenovus must develop facilities to accommodate their workforce. Borealis is a conceptual camp located at Narrows Lake and is a selfcontained facility that will house 2400 workers. The camp was developed using forward thinking ideas, modern technologies, and a focus on the environment. A complete site layout of this two-phase camp has been created, with full design considerations for water and wastewater management, solid waste management and power requirements. Innovative ideas have been implemented in the design of Borealis, such as on-site composting, a “bottle-free camp” policy and the use of reclaimed water to minimize environmental impacts. TEAM 2 - BOOTH 202 TEAM 4 - BOOTH 204 Elbow River Pedestrian Bridges Albert Lee, Andrew Richardson, Brandon Farrell, Coltin Walsh, Connor Lemieux, Jeff Lin, Jonathan van Aggelen, Kyle Strachan, Oleksiy Manukyan, Raymond Wong, Samuel Leung In June 2013, a massive flood raged through the City of Calgary, destroying three pedestrian bridges along the Elbow River. In an effort to rebuild, ClearSpan Engineering has been tasked to design a replacement bridge for the Riverdale Avenue location. Through careful consideration, a cablestayed bridge was chosen for design. The cable-stayed bridge design is capable of withstanding another flood, resembles the previous cable suspended bridge structure, and is an innovated and modern structural system. Detailed structural design and calculations were performed involving static and dynamic analysis of all major structural components. A thorough cost estimation and construction phasing schedule was also prepared, examining the feasibility of the design. The primary deliverable of this project is to present the City of Calgary with a suitable, sustainable, and economically feasible design to be used as a viable replacement for previously destroyed bridges. Pipeline Life Cycle Optimization Azan Jamal, Brett Laidlaw, Elaine Dias, Amir Fardi, Eric Szeto, Eugene Lee, Heng Lin, Keyvan Abedanpourkoushki, Man Tam, Rochelle Belleza, Yusuf Yusuf The purpose of this project is to create a user-friendly Excel spreadsheet that optimizes pipeline life cycle by manipulating line size, pressures, and flow rates for a user-defined pipeline system. The user-defined pipeline system can contain up to five production phases, three commodities, and two lateral pipes that are either injections or deliveries. The data are entered in user forms after which a modifiable visual representation of the pipeline system is displayed. In the analysis section, the spreadsheet follows hydraulic principles by utilizing Visual Basic commands and Excel Solver to calculate pipeline size and commodity batching sequences. The pipeline life cycle is optimized by reducing the erosion rate and pressure cycles in the pipeline. The results displayed include tables for the optimal batching sequence as well as graphs detailing pipeline fatigue in terms of erosion and pressure cycles. TEAM 5 - BOOTH 205 Erosion Control and Stepped Chutes Design Bogdan Masala, Davide Milos, Hanzhe Lu, Thao Cu Water conveyance, slope stabilization, and surface erosion prevention are issues on many large projects in northern Alberta. Team 5 evaluated various engineering techniques to help reduce soil erosion at Suncor Energy’s Millennium oil sands mine. Specifically, the Mine Dump 2 (MD2) and Mine Dump 9 (MD9) drainage channels were evaluated due to their long-standing issues with erosion. At the MD2 channel, the team assessed various bioengineering and commercial erosion prevention techniques that could replace the use of costly riprap in maintaining channel stability. At the MD9 channel, the team evaluated the feasibility of using stepped chutes to replace the existing drop structure and riprap system currently used to control water flow velocity. TEAM 3 - BOOTH 203 TEAM 6 - BOOTH 206 Student Residence - Crowsnest Hall Calgary Design of Pile Foundations for Well Pads Chester Lam, Dmitry Fradkin, Dylan Kramer, Eric Mitchell, Jerry (Brian) Lee Kim Gnok, Keith Jackson, Lael Dilworth, Matthew Njaa, Robert Soos, Robyn Szymoszowskyj, Stuart MacDonald With continued expansion of the University of Calgary facilities and student numbers, it is important to increase student capacity through construction of new student residences. Our team has been tasked with the design of the Crowsnest Hall 11-storey north tower. Crowsnest Hall will house graduate students in one and two bedroom suites. The residence will also include rooms for study, music, a multipurpose room, a common room, and a kitchen. The design of the building will include all fundamental structural engineering elements such as foundation systems, slab/column systems, and lateral forces resisting systems. For each component, we provide the structural design and cost estimates for two different systems and evaluate which systems would be best employed for the project. We also included the design of the single-floor building that links the two towers together. Hao (Arthur) Feng, Jiwan Bariyar, Juan Aguilar, Nathan Lau, Vivian Yeung The goal of this project was to design the most suitable pile foundations for well pads at four different locations based on the subsurface properties at each site. Cast-in-place concrete piles, H-beam and hollow pipe steel piles, and steel screw piles were considered for each site. Each type of pile was designed to resist axial and lateral loading. Site specific environmental factors such as the effects of frost penetration into the soil were also considered. In order to design the dimensions for each pile, the soil properties at each site were determined from the analysis of borehole logs. The most cost effective design that was able to support the specified axial and lateral loadings was selected as the final design. 2015 Capstone Design Fair 8 Civil Engineering TEAM 7 - BOOTH 207 TEAM 10 - BOOTH 210 Debris Flood Mitigation: Pigeon Creek Greywater Reclamation System Arthur Kozlowski, Brendin McCaughan, Derek Ross, Ethan Miles, Jacqueline Smith, Katie Auchterlonie, Michael Cecchini, Michael Murray, Peter Yee, Samuel Frederick D'Arcy Kroeker, Evan Fong, Jan Nowicki, Ruth Laing Rapid snow melt combined with heavy spring precipitation can trigger debris floods, or flows, in mountainous areas with high velocities and large impact forces. In June 2013, one such event occurred in the Pigeon Creek watershed causing significant damage to public and private land. This project aims to assess the risk associated with future channelized debris floods in the Pigeon Creek area, located south of Dead Man’s Flats in the Kananaskis region of the Rocky Mountains. Over the course of three months, 118 channel cross-sections from 11 creeks that had experienced debris flows/floods were studied. The field data were analyzed to determine the flow volumes, impacts, and other parameters expected in the area. These parameters were subsequently used in the design of a debris flood mitigation strategy aimed at reducing the risk of future damage to downstream infrastructure. With water being a scarce resource around the world, water recycling is a topical and relevant design problem. This project encompasses the design of a greywater reclamation system to hypothetically be installed during the construction of a new 400 unit apartment building. The project includes the logistics of collection of the greywater as it leaves the apartment units, as well as investigation of the quality. It also includes the design of an “inhouse” treatment system for the greywater and the redistribution of the water for reuse. The treated water will primarily be used for toilet flushing within the building, and shall be treated to the Canadian Guidelines for Domestic Reclaimed Water for Use in Toilet and Urinal Flushing requirements and the EPA Guidelines for Water Reuse. Any excess treated water will be used for laundry wash-water. TEAM 11 - BOOTH 211 TEAM 8 - BOOTH 208 Biogas Collection and Energy Recovery at Shepard Lagoons Connor Scheu, Kirby Ma, Michelle Mah, Yuan Zhou The wastewater treatment plants in Calgary are capable of removing more than 95% of the impurities from wastewater. The leftover impurities, known as anaerobically digested sludge (ADS), are stored in the Shepard Lagoons until ready to be reused for biosolid land applications. During storage, the ADS undergoes further anaerobic biodegradation, producing a methane rich biogas. By introducing a capture system over the lagoons it is possible to prevent the release of this greenhouse gas and to use the biogas as a source of clean energy. The simplest option is to flare the biogas, converting the methane to carbon dioxide, decreasing the global warming potential. Alternatively, the biogas can be compressed and stripped of hydrogen sulfide to be used as a natural gas fuel source, or a gas engine generator can convert the biogas into electricity and heat. Sandy Hollows Sustainable Subdivision Courtenay Farrington, Heather Graffunder, Jenn Currie, Malithi Fernando, Michael Dirk, Phil Nettleton, Ross Thompson, Sahil Sharma, Vlad Tabelev Sustainable development is often synonymous with densification in urban environments, leaving development in rural or semirural settings largely unchanged. Westland Design aims to address this need and provide a more ecologically sensitive and community-centred alternative to traditional acreage living in Alberta. Sandy Hollows is a sustainable, semirural subdivision located west of Edmonton. Its hybrid design combines traditional country living with the environmental benefits of a cluster community. The multidisciplinary team at Westland Design optimized the site layout, storm water management plan, road design and grading to provide innovative solutions while working within the constraints posed by market demand, site characteristics and stakeholder interests. Aiming to apply LEED Neighborhood Development standards, Sandy Hollows implements key principles of sustainable design to minimize impact and take an active role in reversing environmental damage. TEAM 9 - BOOTH 209 Rio de Janeiro Airport Master Plan Alexandre Frotten, Amulpreet Bassi, Ariel McCance, David Weisbrot, Gina Yee, Jordan Hogan, Luna Velez, Sahaer Moghareb-Samadi, Taylor Hudson, (Tom) Li Shu Yang, Valentina Fazio, Zachary Skotheim The Brazilian government has reached a 30-year concession agreement to privatize the Rio de Janeiro (Galeão–Antonio Carlos Jobim) International Airport. The agreement requires the expansion of the runway and taxiway systems as well as significant expansion of the aircraft aprons and passenger terminals. Due to limited time and resources we focused on expansion design of the runways, aircraft apron and passenger terminals. Cargo terminal expansion and ground movement transportation were excluded. To determine future demand, the projected volumes of passenger and aircrafts were required. These volumes include both international volumes, domestic volumes, peak hour volumes and aircraft types. The projected volumes determined the capacity required of the new runway and taxiway system, the size of the aircraft aprons and passenger terminals, as well as the expansion timeline. 2015 Capstone Design Fair 9 ELECTRICAL & COMPUTER ENGINEERING Electrical & Computer Engineering TEAM 1 - BOOTH 301 TEAM 4 - BOOTH 304 Fi+ Web-based Application for Well Mapping Allan Liang, Beenish Khurshid, Jobelle Firme, Nicolas Valera, Ralph Kimoden, Sean Mikalson Behar Ibishi, Christopher Dart, Daniel Sheedy, Jennifer Jaafar, John Chau, Piril Kusoglu, Thomas Condon We have developed an Android application (Fi+) that will allow users to create spontaneous fitness events and easily connect with others who want to participate. Our intention is to use social networking to stimulate real-world social interaction and encourage physical activity. With Fi+ you will have an easier time finding and joining events that fit your schedule—saving your time and energy for the game. We have designed a modern, web-based application for the purpose of replacing an older software program, known as PetroDesk. This new software enables the user to display well data such as location and output on a digital map and works with a web browser such as Windows Explorer 10 and Google Chrome. Since this is a web-based application, a user may easily access data from almost anywhere.

Hamza Elkhair, Ian Macaulay, Stephen Burchill, Thomas McEvoy, Yunus Emre uSchedule allows students of UofC to plan their schedules for a semester quickly and efficiently, by displaying all the possible schedules that can be made (without conflicts) given a list of courses. Once they can see and review each timetable option, they simply pick their favorite and sign up for those sections via myUofC. TEAM 6 - BOOTH 306 TEAM 3 - BOOTH 303 Traffic Control Unit Aamar Maqsood, Adnan Ishfaq, Dilpreet Dhillion, Saad Naeem, Yussef Akl, ZiXuan Mei Purpose of our project is to develop a solution that will reduce congestion in downtown area.We aim to facilitate downtown Calgary commute during the peak rush hours. After studying the root causes of delayed traffic movement we found our culprit to be distracted drivers. Drivers that aren't paying attention to when the light turns green cause extra delays in traffic movement which causes the rush hour to last longer and become more excruciating. Our solution is to notify mobile users, through their cellphones, of a changing traffic light, several seconds in advance, so that they have are attentive and have ample time to react without holding up traffic. 2015 Capstone Design Fair Hype Train Becker Luu, John Flores, Muhammad Sarwar, Tieulong Trac, William Kwok Hype Train is a web platform for pro-players and fans to connect. Through this platform, fans can crowd-fund matches between their favourite professional gamers. Professional players must then reach an agreement with regard to the match date, funding goals and payouts. Funding will then commence and once a minimum fundraising threshold has been reached, the match will commence and be streamed online for fans to spectate. 11 Electrical & Computer Engineering TEAM 7 - BOOTH 307 TEAM 10 - BOOTH 310 Project Columbia Power System Protection Anas Ibrahim, Jaclyn Chang, Jan Ong, Mariam Dost, Nguyen Jack, Ryan Damm Dilshad Palani, Ebad Hanafi, Jaime Lopez, Mohammad Butt, Umer Pervaiz Our project is a mobile application for the Android operating system that can be used for searching and displaying hiking trails in the Columbia Valley. We are working with the Columbia Valley Greenways Trail Alliance (CVGTA). The goal is to provide users with an application that can help people that love hiking, skiing, cycling, and many other types of outdoor activities, to find the perfect trail for them! Our application can be used to search trails that accommodate specific types of activities and amenities, and then provide the user with information for each trail. The user taps on the name of a trail and is provided with a description of the trail, directions to the start of the trail, other users’ comments and pictures of the trail! This project consists of designing a power system protection system for a high-voltage substation. The substation provides power to a pipeline pump-station by reducing the high voltage of the transmission lines (144 kilovolt) to a lesser, more usable value (6.9 kilovolt) via a step-down transformer. The protection system uses relays and circuit breakers to prevent damage to the electrical equipment and the adjoining transmission lines in the event of abnormal behavior. Relays are digital computing devices which detect information about the condition of the power system. This information is recorded and manipulated to determine if the system is behaving normally. If a significant fluctuation are detected, the relay communicates to a nearby circuit breaker to disconnect the affected portion. The objective is to only disconnect the affected area while allowing the remaining areas to continue on as normal. TEAM 8 - BOOTH 308 Automated Testing and Simulation Tool Adam Mah, Kyle Petric, Nilanka Ranasinghe, Sidra Malik, Wiam Katoue The Automated Testing and Simulation Tool (ATST) performs standard control system testing procedures on Enerflex standardized control systems and reports the results of the testing. It is split up into two parts: The ATST Programmable Logic Controller (PLC) Program and The ATST Reporting Tool. The ATST PLC Program is a software program that performs standardized tests on existing Enerflex standardized control programs. The ATST Reporting Tool controls the ATST PLC Program, then reports the results of the tests. The ATST Reporting Tool also acts as a user interface in order to allow user control, visually report results, and report any test failures. The ATST reduces testing time and automates repetitive testing tasks in current Enerflex standardized control systems. The ATST also reduces human error in testing and streamlines reporting. TEAM 9 - BOOTH 309 TEAM 11 - BOOTH 311 Dynamic Thermal Line Rating Angela Chan, Basil Mahmoud, Josh Krahn, Redjie Olino, Roscoe Llamzon To implement a dynamic thermal line rating system to estimate the sag and calculate the clearance of a line. Our device consists of a MicroController controlling a triple axis accelerometer for angle measurement and an XBee Radio for transmitting information. Our project sponsor, AltaLink, has the ability to identify certain spans that contain clearance hazards, such as trees or roads. These specific spans are the limiting factor for how much current is allowed to be transmitted along the line. Our device is installed on the critical spans between two transmission poles where potential clearance hazards are present. A full scale implementation would include a more rugged enclosure, and possibly, a different type of communication protocol that is more in line with AltaLink's current communication systems. Issuedin John Ma, Kim Francis, Mitchell Edmund Lee, Navid Pourmomtaz, Philip Athyal, Tim Driedger Oil and gas construction projects in Alberta face serious shortcomings when it comes to productivity and effective communication. The implications of this are high overhead costs, wasted effort, and schedule delays for moderate cases. More extreme cases result in legal disputes or shutting down of the project. A simple solution is to ensure project status data is effectively and efficiently communicated throughout the duration of a project. IssuedIn aims to provide a portfolio of support tools for project managers, so that they have high accessibility to the most up-to-date and accurate information regarding the activities of their project via an independent web application module for management and tracking of project issues. This application bridges the communication gap between the job site and the office. This module demonstrates the feasibility and applicability of the overall proposed solution. 2015 Capstone Design Fair TEAM 12 - BOOTH 312 Transformer Noise Mitigation Using Active Noise Cancellation Ashley Davison, John Holmes, Josh Spackman, Kody Haugli, Shaun Woykin In previous years, passive noise cancellation, in the form of structural barriers, was used as a means to control unwanted noise. These barriers, however, can be obtrusive and are not aesthetically pleasing. For these reasons, AltaLink requested a solution driven by electrical engineering components to reduce the noise radiating from their transformers by 5 decibels. The transformer we focused on emits a 120Hz hum that needed to be reduced. Active noise cancellation was chosen as the solution to the transformer noise. Active noise cancellation involves reading the source noise signal, which in our case is the transformer noise, into the processing board and using it to create a new signal of the same form, only shifted by 180°. This new phaseshifted signal is emitted from a speaker and added with the source signal into the air to ultimately cancel the transformer noise. 12 Electrical & Computer Engineering TEAM 13 - BOOTH 313 Enhanced Wind and Solar Power Forecasting Model for Alberta Hasan Qureshi, Jiajing Lin, Li Yi, Liam Nodwell, Pierre Carlo Panorel, Yuxiang Huang, Zhao Luo Our project is a forecasting tool for reliable wind and solar power forecasting in Alberta. It allows users to predict the power output of existing wind farms or potential wind farm sites based on various weather factors, historical outputs in similar weather conditions and terrain characteristics. Having access to this data is critical to power markets being able to make important decisions for load demands, power contracts, maintenance, and scouting areas rich with wind and solar energy. In the future, a user will be able to access our power forecasting tool both online and offline in a visually appealing and easily understandable format to obtain reliable wind and solar power forecasting results. TEAM 16 - BOOTH 316 UMDL Designs Corey Bird, Dallas Rathbone, Eric Wu, Jenessa Fett, Kelsey Shields, Patricia Groves UMDL Designs is a team of electrical engineering students who have designed a universal multichannel datalogger. The idea developed after a discussion with one of the university’s professors who required a datalogger that would work with his unique set of biomedical sensors. From this discussion a solution arose that included a datalogger that has a universal interface so that any type and number of sensors could be connected to it. While this datalogger has many potential applications, the initial development has been focused on the biomedical industry, specifically, hospital applications. There is a growing trend for smart device usage among physicians, so a datalogger that can easily and wirelessly connect with the user’s device to transfer real-time data and alerts has been identified as valuable. UMDL’s datalogger addresses these concerns while maintaining a sleek form-factor and sufficient battery capacity. TEAM 14 - BOOTH 314 Dialog Convenience Store and Gas Bar Brynne Wilson, John Butcher, Maryam Adeyemo, Michael Luik, Ryan Burke The objective of our project is to create standard electrical schematics and drawings for a gas bar and convenience store that meets the strictest safety codes (fire, electrical, environmental, etc.) in Saskatchewan, B.C., and Alberta. A convenience store, an underground tank nest, a gas bar with a canopy, a cardlock and a monument sign are among the main buildings/merchandise considered. A large part of the final solution is encompassed by the following drawings/specifications, to be reviewed by a professional engineer in order to ensure all systems are safe and constructible: Conduit Power & Data, Exterior Lighting & Detail, Duct Detail, Gas Bar & Cardlock Underground Conduit, Store Pathways, Line Voltage Gas Bar Pathways, Cardlock Pathways, Store Lighting, Gas Bar Lighting, Low Voltage Systems, Cardlock CCTV & Lighting, Propane Tank, Underground Tanks/Sump Pumps, Single Line Diagram, Fire Alarm Riser and Lighting. TEAM 17 - BOOTH 317 ❄Let it Snow❄: Roomba for Your Driveway Christopher Bowal, Christopher Deimert, Michael Herrmann, Nigel Gutzmann, Troy Graham Anna, a fearless optimist, sets off on an epic journey - teaming up with rugged engineers and their loyal snow-clearing robot - to find her sister Elsa, whose icy powers have trapped the kingdom of Calgary in eternal winter. In a never-before attempted feat of bravery, the snow-robot battles Everest-like conditions in a race to save the kingdom. From the outside, Elsa looks poised, regal and reserved, but in reality, she lives in fear as she wrestles with a mighty secret - she was born with the inability to shovel ice and snow. Haunted by her weakness, Elsa has isolated herself behind a driveway filled with untouched snow. Her mounting emotions trigger panic, accidentally setting off an eternal winter that she can't stop. She fears she's becoming a monster and that no one can help her… Rated R. 132 Minutes. TEAM 15 - BOOTH 315 Software Generated Single Line Diagrams Brett Pelletier, Edmond Chih, Nathan Yu, Roshaan Ali, Sina Arman Alberta Electric System Operator is responsible for the safe, reliable and economic planning and operation of Alberta's interconnected electric system. The long-term planning group utilizes PSS®E, a transmission planning software, to develop conceptual alternatives for the entire province of Alberta. A comparison between the original base case and new case provides information to draw a single line diagram. Subsequently, these diagrams are used to help visualize additions, subtractions, and unchanged components on transmission lines. These single line diagrams are then painstakingly drawn in Microsoft Visio since PSS®E does not contain an in-house drawing tool. Our project objective is to develop a custom compare and draw tool for the development of future conceptual alternatives, while streamlining workplace efficiency. 2015 Capstone Design Fair 13 Electrical & Computer Engineering TEAM 18 - BOOTH 318 Time To Failure Battery Life Monitor Justin Huskic, Kai Rasporich, Nick Saar, Robert Hanna, Robert Pipo Monitoring the current and voltage of a sealed lead acid battery pack the Time To Failure Battery Life Monitor predicts the remaining usage time for the users equipment. The monitor allows a user to select a desired time remaining threshold. Once the threshold is reached the monitor will deliver a message using an existing Ethernet gateway, sending an email to inform that the threshold has been reached and mitigating unexpected power failure. The email notification will also deliver the approximate time remaining and the current voltage level. The monitor logs the information (current, voltage, and temperature) of the battery pack on a removable SD card to determine usage characteristics and battery health. This enables the user to replace/ repair battery packs in a timely and cost effective fashion. TEAM 19 - BOOTH 319 Upgrade to Human-Machine Interface on an Offset Printing Press Arpita Saha, Maryam Abdullah, Musse Abdullahi, Venkatesh Amararajan, Zohaib Rashid Makeda press has an offset printing machine from the 1980’s with an archaic user interface and a broken memory system. Due to the broken memory system, settings must be recorded manually by the operator if he/she wishes to save them from one print job to the next. Our project is a prototype that demonstrates how a PC-based user interface and file system can be easily integrated with the current system to enhance operator experience. In our system, the operator interacts with custom software built by our team to control the motor, save and recall settings. TEAM 21 - BOOTH 321 Power Quality Monitor Ayesha Irfan, Bryson Siemens, Neena Marasinghe, Nolan Kelly, Roberto Cavedoni Our project involves designing, building and testing a Power Quality Monitor (PQM) Board. This device works by obtaining current and voltage data from energized systems. This data is sent to a microprocessor for further analysis and then sent to a Laptop or Personal Computer to study the quality of the power in the system. TEAM 22 - BOOTH 322 A Hardware Solution for Mapping Venues Christopher Burke, Christopher Yee, Ciaran Geaney, Samanpreet Jammu, Sumit Narang Modern sound system and acoustic technology allows for the directionality of speakers to be configured remotely using actuators in order to optimize sound quality in a venue, and thus improve the experience of event attendees. Software which is used to find the optimal speaker configurations requires a 3D map of the venue in order to operate. The system developed by our group acquires data that can later be used to generate these 3D maps. The hardware solution utilizes a laser distance meter that can be rotated about two axes of motion using stepper motors to collect distance measurements from around the inside of a venue from a common origin. The acquired distance measurements in 3D space allow for a map of the venue to be produced. TEAM 23 - BOOTH 323 DRESSFRESH - The Fully Automated Garment Refresh System TEAM 20 - BOOTH 320 Adam Wagner, Aram Razouki, Ashley Fernandes, Jason Woo, Kevin (Yueh-Chen) Lin, Patrick Mah Partial Discharge within a Substation Washing clothes after a single day’s use is a waste of time, money, and energy. Most of the time, the garment is not dirty and simply needs to be refreshed. With the push of a button, the DRESSFRESH system aims to remove wrinkles and eliminate odour-causing bacteria from lightly worn clothes using a mixture of steam, heat, and air. The design of DRESSFRESH was sponsored by aspiring entrepreneur – Aram Razouki – and completed as a joint venture between the Mechanical and Electrical teams. The Mechanical Team is responsible for designing and building the housing unit to incorporate key components, and the Electrical Team is focused on creating the control system and integrating the electronics of the product. Our control system has been engineered to maximize the refreshing cycle within five minutes, while ensuring safe operation during the process. Ahmed Uqaili, Nadun Wijesinghe, Tayyab Tahir Mohammad, Uzair Syed, Zoheb Hassan Syed Partial discharge is a phenomenon that occurs within high voltage equipment. When insulation in an electrical system experiences high voltage stress, small electrical currents or even sparks can occur through the voids in the insulation. These electrical sparks are referred to as partial discharge (PD). Team F-5-I has researched and implemented a solution to detect and continuously monitor partial discharge occurring within a transformer in a substation. Using an oscilloscope, an ideal waveform of partial discharge was simulated. The simulation is then amplified and filtered through electrical circuitry before being inputted into a microprocessor. Furthermore, the signal is transmitted wirelessly to a laptop where it is measured and stored for further analysis. Partial discharge monitoring is a crucial procedure in the power industry for assessing the condition of all electrical equipment in order to maintain its reliability, efficiency and lifespan. 2015 Capstone Design Fair 14 Electrical & Computer Engineering TEAM 24 - BOOTH 324 Wireless Power Transfer Angus Ho, Jingwen (Belinda) Huang, Joey McGraw, Sajna Massey, Tugso Batjargal TEAM 27 - BOOTH 327 Sensor Solution for Wireless Tuning of Acoustic Instruments How often is your phone flashing a low battery warning? How often do you forget your phone charger at home, leaving you with a dead phone in the middle of the day? We have designed a transmitter and receiver unit that transfers power wirelessly to an iPhone. Our product allows smartphone users frustrated by poor battery life to utilize a convenient new way of charging. This wireless charger can charge over a distance and is much more convenient than inductive charging pads which require contact with the phone. You can easily use your phone while it is charging and multiple devices can be charged from a single transmitter. Wireless charging is the next step in charging electronic devices and has gained momentum in companies such as Ikea, Samsung and Intel. The Sensor and Wireless Applications Group has designed and prototyped a wireless guitar tuner. By sensing the mechanical vibrations of a guitar’s body instead of relying on sound, tuning can be done even in noisy environments. The tuner will wirelessly transmit the tuning information to either a display on an Android smartphone or a Garmin smartwatch display. The intuitive user display will show the closest note to the note being played, whether it is sharp or flat, and how far offpitch it is. The lack of a screen directly on the tuner allows it to have a reduced form factor which will be unobtrusive to the user. TEAM 25 - BOOTH 325 TEAM 28 - BOOTH 328 Well Leak Detection Tool On-Board Diagnostics Monitoring and Tracking Breanne Fisher, Glen Yanosik, Jesreen Jamaldeen, Lingjie Ye, Raymond Yip Production logging uses a combination of tools to determine the flow rate of different phases and show where fluid is entering or exiting the borehole. The focus of our project is leak detection using an audio sensor. Current convention relies on the interpretation of leak location by an experienced operator. This method is time consuming, inefficient and prone to error. The Leak Hunters have developed a prototype audio recording tool. The data collected is sent up-hole via a robust and established telemetry system. A program processes the data and correlates the output with known leakage signatures. From cross-correlation, the operator can be confident in distinguishing if the source of the noise is from a leak, instead of relying on qualitative analysis. This technology will reduce operator error, production downtime and add further functionality to existing production logging tool strings. TEAM 26 - BOOTH 326 Design-Build of a Hydroelectric Generator Airgap Measurement System Blaine Daugherty, Brad Coleman, Navdeep Gill, Salima Kairzhanova, Tyler Schwebius The measurement and alignment of the space between the stator and rotor of a hydroelectric generator (airgap) is critical to generator operation. Currently, airgap measurements of hydroelectric generators are done using either feeler gauges or electronic sensors where the raw data needs to be manually processed to be useful. This takes time from a human resource perspective and can prolong outage times due to the laborious task of taking the airgap measurements. The excessive use of cabling in the current system creates inefficiency in setup time and is a significant safety hazard. The airgap measurement system we have designed and constructed performs a fully automated measurement of the airgap using wireless technologies to collect and synthesize data. This decreases the time needed to take these measurements and reduces the skill set needed by the operator to amass the data. 2015 Capstone Design Fair Ian Haigh, Jules LaPrairie, Michael Rohs, Pouyan Keshavarzian, Stephanie Hladik Erin Dekker, Hasitha Anisingaraju, Mac Tonogai, Reeta Suman, Shivani Tata The purpose of this project is to improve driver safety for offsite trips. A vehicle’s On-Board Diagnostics System (OBDII) tracks data such as RPM (rotations per minute of the wheels). A Raspberry Pi (RPi) connects to the OBDII to extract and filter the data from the vehicle. The data is stored on an SD card on the RPi until the end of the trip. It is then transmitted over WiFi to a database in the cloud. This data can be analyzed to study driver behaviour, and to give insights to the situations they are faced with. This system could be further expanded by gathering more data from the OBDII, or adding a video camera inside and outside the vehicle to better track the driver's actions. TEAM 29 - BOOTH 329 DC-DC Solar Electric Car Charging Station Anenya Yohannes Mebrhatom, Gabor Paroczai, Kevin Ka-Fai Ma, Nirikshan Kamalakar Maditha, Zenel Gajtani Our group aims to solve the problem of charging electric cars in remote locations where there is no access to the electrical grid. Our solution is to design and construct a direct current to direct current (DC-DC) charging module prototype, which is more efficient than the standard direct current to alternating current to direct current (DC-AC-DC) method. This prototype will use solar energy as the power supply, a charge controller to regulate the voltage and current produced by the solar panel, and a nickel-metal hydride battery bank to store this energy. Our innovation for this project is charging the battery bank piecewise or by battery module using a microcontroller and relays as a control system. Once each battery module within the battery bank is fully charged, they are connected to each other in a string (series configuration) by the control system and can now charge an electric car battery. 15 Electrical & Computer Engineering TEAM 30 - BOOTH 330 Navi-Sol: Solar Powered Watercraft System TEAM 33 - BOOTH 333-DUPLICATE BOOTH NUMBER 2D Microwave Imaging Yin Hao Chen, Zixin Chen, James Decoux, Danielle Lam, Kyle Skelly, Alexander Ta Adam Deunk, Anton Deriabine, David Ryan, Marshall Doig, Stefan Lund Team Navi-Sol designed the electrical systems for a solar powered watercraft. The motivation for this project was to provide an environmentally friendly method for recreational travel over water. Systems that were designed, built, and tested include MPPT (maximum power point tracking), battery control, battery monitoring/cell balancing, and user feedback. The solar cell panel design and construction and interface to the battery was also done by the team. The purpose of these systems was to achieve the maximum power output from the solar cells to charge the battery and provide power for the motor. When there is sufficient sunlight to power the motor, the battery will also be charging. In times where there is not sufficient sunlight due to cloud cover, night time, etc., the charged battery will act as a back up power source for the motor to run off of. The Automated Microwave Imaging (AMI) group has worked closely with their Industry Sponsor, the Tissue Sensing Adaptive Radar (TSAR) Lab on campus to produce a 2D Microwave Image Scanner. This device uses microwave radio waves of varying frequency to scan a flat object of unknown electrical properties, in order to understand the composition of the material. The device uses an emitter antenna and a receiver antenna array to perform this interrogation. The process is automated using LabVIEW, a Graphical User Interface program that allows for entry of patient and scanning parameters, computes mathematical calculations, and externally controls the movement of the emitter antenna in order to produce an image representation of the scan. The future of this technology will be to develop the ability to use the antenna in 3-Dimensional space to allow doctors to perform noninvasive breast cancer screening. TEAM 31 - BOOTH 331 Integrated Renewable Energy Modelling Tool Anirudh Chopra, Madhav Narendran, Robert Panchuk, Yi Zhi Wan, Zachary Lesko Our project is an accurate system-level model of electrical production from renewable generation sources (e.g. wind and solar) accompanied with storage in correlation to amount of electrical demand for a specific application. This project is designed to serve as a demonstrative tool depicting the optimized size of components based on amount of generation possible at a specific geographic location. Core facets of this project are: a system case study, a load profile model, and a component sizing tool. Ultimately, this software intakes weather data at a specific location and user demand, and determines the amount of generation possible on an hourly basis. It will then optimize the number and size of the components based on criteria outlined by the user. A modelling software which takes into account hourly variability in generation and scales for various applications is currently not available. TEAM 34 - BOOTH 334 4" Caliper Pipeline Inspection Tool Alaa Yousif, Darren Schmautz, Lucas Pacentrilli, Russell Holmes, Spencer McLeod The Caliper tool provides necessary information about a pipeline's inner diameter (ID) using a user defined 8, 16 or 32 channels that comprises of Hall Effect sensors fastened at the end of Caliper arms. This information helps to ensure that other pipeline inspection technologies will safely navigate through the pipeline. The tool gets propelled through a pressurized pipeline and records the following data: Hall Effect, Internal/External Pressure and Temperature, Distance and Spatial (Acelerometer, Gyroscope). TEAM 32 - BOOTH 332 Electrical Design of a Prefabricated Skid-mounted Oilsands Slurry Pumphouse Barett MacLeod, Curtis Craig, Jordan Lienau, Kuntal Pandya, Samra Saeed Modern oilsands mining operations in Alberta utilize hydrotransport pipelines as an economical alternative to conveyor systems for transporting mined oil sand from the mine to the processing facility. Hydrotransport pipelines can extend as long as 40 km, requiring large slurry pumps to be installed at intermediate locations along the pipeline. Our team has designed a skid-mounted pumphouse module for this application, and drafted a complete electrical drawing package supported by power system studies modelled with ETAP. The pumphouse skid is designed to be constructed completely offsite, substantially reducing construction costs for the project. The pumphouse skid comes complete with high and medium voltage transformers, distribution equipment, process motors and pumps, and supporting equipment such as an integral bridge service crane, building lighting, and life safety systems as required by industry standards and best practices. 2015 Capstone Design Fair 16 GEOMATICS ENGINEERING Geomatics Engineering TEAM 1 - BOOTH 401 TEAM 4 - BOOTH 404 Beakerhead: A Geomatics Perspective Wetland Delineation Using Remote Sensing Techniques Carson Bannon, Xunchen Bao, Shirley Chan, Anna Ross The BeakerHead Team aims to communicate Geomatics Engineering in a form that is innovative and engaging to the general public. We believe Geomatics Engineering is the science and technology behind the concept of "where". The group will use BeakerHead to its advantage by creating an experience that integrates aspects of Geomatics Engineering with art. Ultimately, the audience will gain a better understanding of Geomatics in an artistic and visually astounding way. TEAM 2 - BOOTH 402 Road Sign Detection Using LIDAR Data Nicole Beier, Andrea Bordieanu, Sarah DeMong, Raymond Khuu This project utilizes a set of mobile Light Detection and Ranging (LiDAR) data and process it to automatically detect road signs. Historically, data was obtained through static laser scanners with time consuming setup or photogrammetric data. Presently, data can be acquired on-the-go through mobile terrestrial LiDAR scanners, increasing the quantity, quality and rate at which the data is obtained. Detection of navigation attributes, specifically road sign detection, has many applications such as determining the condition of the signs, or updating mobile mapping systems and inventory of useful navigation information. Once data has been obtained, the sign detection can then be performed, using the Random Sample Consensus (RANSAC) algorithm and using the Point Cloud Library (PCL) and libLAS C++ libraries. Planes whose normal face the direction of travel of the mobile LiDAR data are most likely to be signs. TEAM 3 - BOOTH 403 High Precision Survey Network Clayton Berg, Jeffrey Cornish, Luke Meister, Walter Morvillo The project requires a survey of high precision network control points near and on campus connected to the Calgary high precision control using static GNSS measurements. This network connected a secondary network that will be used by future Geomatics Engineering students using high precision traverses. These traverses throughout campus will be done by utilizing a number of high orientation points which were fixed using intersection and trigonometric heighting. Instruments such as the EDM and meteorological handhelds are to be calibrated throughout the project to get the best possible results in different weather conditions. Finally, all data will be plotted using ArcGIS to get a fina l representation of all fieldwork performed. 2015 Capstone Design Fair Aref Ahmed, Samridhi Anand, Kurt Bioletti, Robert Fung Wetlands provide many advantages for society. These advantages include water purification, preventing erosion, and creating biodiversity. It is in our best interest to ensure the current and future sustainability of these areas. Remote sensing techniques allow for the analysis of an area, without having to visit the area in person. Using images taken by satellites, generation of different types of indices which describe various features of the area can be done. Using these indices, generalizations about the area can be found, and thus utilized to either monitor the area, or find areas of similar type. This is especially useful for wetlands area, as they are hard to traverse on foot, and ground level surveys can become expensive. Using remote sensing techniques, safety of the researcher can be ensured, while potentially reducing costs. TEAM 5 - BOOTH 405 Behavioral Context Detection Using Smart Phones Rafael Canelon, David Krawczuk, Luis Rodriguez Mendoza, Jean Vianney The group is developing an Android sports app that utilizes behavioral context recognition. The app will have a step counter and will track how much a person walks and runs. It will use this information to estimate calories burnt, etc. The app uses the cell phone’s accelerometer. The group had to gather data in order to be able to tell when a person is walking, running, or standing (behavioral context recognition). This task included data pre-processing, feature extraction and feature classification in order to assess the effectiveness of the accelerometer data and the activity class thresholds. TEAM 6 - BOOTH 406 Terrestrial Laser Scanning for 3D Building Modelling Purposes Juan Aguilar, Jiwan Bariyar, Hao (Arthur) Feng, Nathan Lau, Vivian Yeung The group has been assigned to complete tasks necessary to develop an accurate georeferenced 3D model of a building on the University of Calgary (U of C) campus. The model will be created from observations gathered using terrestrial laser scanning methods. The main project tasks include: selecting an appropriate building to model at the U of C, selecting equipment and methods to establish a control point network surrounding the chosen building, performing field work to gather scans representing building surface data, combining every scan into one registered point cloud, and generating an accurate building model from the final registered point cloud. After a final 3D model is created, attempts will be made to upload a condensed version of the model to Google Earth. 18 Geomatics Engineering TEAM 7 - BOOTH 407 High Sensitivity GPS & Analysis Fengyu Cai, Blake Lange, Willem Smienk, Venice Tang This project involves the development of a program to read, process, and analyze GPS data. The main goal of the program is to compute the position and velocity of various receivers and compare the sensitivity in various environments. The project as a whole had the following requirements: work with static or kinematic data, be able to work standalone using pseudorange and Doppler (carrier phase rate) measurements, apply available augmentation corrections to improve positioning accuracy, assess the performance of high-sensitivity receivers in a variety of environments in both static and kinematic modes. Lastly, comparing the result of the high-sensitivity receivers with geodetic grade receivers and assess the strengths and weaknesses of the various different receivers within various environments. TEAM 8 - BOOTH 408 Valve Placement Strategies in Oil Pipelines Gerald Andreiuk, Jordan Colebrook, Thomas Howat, Nicholas Weir In collaboration with an industry sponsor, the group has undertaken the task of analyzing one of the most crucial risk mitigation strategies in the pipeline industry, valve placement. Valves are essentially a means of isolating flow in the event of leaks, ruptures or maintenance. In the initial phase, the group compared the environmental impacts of both fixed distance and variable distance spacing regimes for simulated terrain samples. The group then analyzed digital elevation models and created a realistic scenario, representative of the topography and geographic features a pipeline could encounter when transporting bitumen from Alberta to the Pacific coast. Through analyzing the potential volumes released in the event of a pipeline rupture, the group was able to conduct a final comparison of the two methodologies, as well as an independent engineering assessment in determining the placement of valves. 2015 Capstone Design Fair 19 MECHANICAL & MANUFACTURING ENGINEERING Mechanical & Manufacturing Engineering BOOTH 501 BOOTH 504 Liquefying Hybrid Rocket Propellant Test Apparatus Electric Arctic Rover Project Ciaran Dunn, Garrett Gustafson, Marwa Amery, Matthew Kindree, Przemyslaw Iwaniec, Scott Stanger Hybrid rocket engines differ from conventional rocket engines by using a fluid phase oxidizer in conjunction with a solid phase fuel. However, the mechanism by which the fuel liquefies and mixes with the oxidizer is not well characterized. Thus, the purpose of this project was to design an apparatus that can visualize the liquefying process and enable computer simulation of the experiments. The designed apparatus consists of two major components: a flow conditioner and a combustion chamber. The flow conditioner provides a steady fully-developed oxidizer flow to the combustion chamber. This type of flow simplifies the transition to computer modelling. Inside the combustion chamber, a strip of fuel is ignited and the behavior of the combustion is studied through the glass side walls. Test conditions are measured with pressure and temperature sensors located throughout the apparatus. BOOTH 502 Independent Dual Output Continuously Variable Transmission for a Bicopter Brendon Kerber, David Stewart, Jungyo Choi, Taylor Townsend, Wesley Van Harberden A typical bicopter uses two motors, one to drive each individual rotor. Efficiency can be improved by using a single, larger central motor. The output from the central motor must then be transferred to both rotors using a dual output transmission, which splits the motor input into two outputs, one to each rotor. To improve control and efficiency, a continuously variable transmission (CVT) will be used. A traditional transmission uses gears to manipulate the output speed and as a result has a limited number of fixed gear ratios between the input motor speed and the output speeds. A CVT allows for continuous variation between the motor input and the output speeds allowing the motor to operate at its peak efficiency while changing the speed. The speed of each rotor will be controlled independently allowing for control of complex maneuvers. BOOTH 503 Highly Maneuverable Autonomous Underwater Vehicle Ahmed Al-Mahdi, Daniel Anhorn, David Haehlen, Marshall Staples, Matthew Szczesny, Quinn Hepburn A Highly Maneuverable Autonomous Underwater Vehicle (HMAUV) that is capable of performing complex maneuvers inside underwater caves and other confined spaces where traditional underwater vehicles cannot penetrate. The vehicle is neutrally buoyant in all the vehicle’s attitudes (roll, pitch & yaw configurations). The mechanical and electronic aspects of this HMAUV provides space to integrate a full suite of sensors including a DVL, IMU, Altimeter, 180-degree tiltable color camera, and an acoustic hydrophone array. Some primary goals of the HMAUV will be to conduct survey missions and detect and map submerged wrecks and rocks that could be hard to be navigated by commercial and recreational vessels. 2015 Capstone Design Fair Cory Genovese, Gavin Williams, Kayla Olde, Kevin Hendrickson, Luke Ryan, Matt Howorko The goal of this project is to create an electric vehicle for use in Arctic conditions that will cause minimal environmental disruption when in operation. The design of the vehicle is based on the pre-existing version designed by the University of Calgary Robotics Laboratory for mining operations. The vehicle must have a top speed of at least 10 mph and be able to transverse a 10 by 10 mile area without requiring battery recharge. The vehicle must also be able to climb over objects and up inclines of at least 45 degrees. The vehicle sub systems must be modular and easily serviceable. The main project focus is the design of the track system and drive train. Although initially the vehicle will be manually controlled, measures must be taken so that autonomous control can be implemented in the future. BOOTH 505 ASME Student Design - Remote Inspection Device Anh Viet Le, Daniel Faszer, Jashan Makan, MerrylArokiasamy, Naanak Sodhi, Tyler Gravelle The American Society of Mechanical Engineers (ASME) hosts an engineering design competition each year - this year’s competition involves designing a small payload delivery vehicle that can traverse rough and disaster ridden terrain. Vehicles are evaluated on energy efficiency, speed, and the amount of payload delivered over a test course that contains a ramp, water, sand, and stairs. Our design consists of two individually driven three armed ‘wheels’ mounted at the front of the main body with each arm having a fixed wheel on its end. This design ensures the stability of the vehicle over sand, water, and stairs. The two rear wheels allows for stability and balance over the steep incline and stairs. BOOTH 506 High Inertia Propeller Austin Mireault, Brendyn Stone, David Dyck, Derek Chen, Jeffrey Woolsey, Jovana Cuzovic Gary Gress, the founder of Gress Aeronautics, has devoted much of his time to the study and development of a tilted rotor system for a Vertical Take-Off and Landing (VTOL) drone. His current design utilizes two basic 13” hobby propellers and an active control system. Our group has been tasked with the design and prototyping of an alternative propeller that self-stabilizes during pitching and rolling movements. The challenge is to balance the need of increased inertia with the additional weight of the design. With this in mind, our design consists of an aluminum ring that is fitted and balanced around the original propeller. This arrangement allows for a low-cost option that can be easily mass produced. 21 Mechanical & Manufacturing Engineering BOOTH 507 BOOTH 510 The Wheelchair Assist: Helping Patients Return to their Wheelchair after a Fall Portable Evaporative Cooler Courtney MacDonald, Dave Morin, Joshua Herauf, Mico Madamesila, Samuel Arulnathan, Yifan Wang One of the greatest physical trials for a spinal cord injury patient is the challenge to return to his or her wheelchair, unassisted, after a fall. Unless a patient has the ideal body proportions suited to this task – arms longer than torso – the effort of raising ones rear-end 18” from the ground without full use of leg, core or hand muscles, and with only the wheelchair to grab onto, is nearly impossible. Our device, designed for spinal cord injury patients with capable arm and shoulder muscles, aids in this task. The Wheelchair Assist is intended to provide lightweight, compact and unobtrusive support to improve the safety, independence, and livelihood of paraplegic patients that depend on wheelchairs for mobility. Bassem Younis, Cameron Relke, Carlo Santos, Dave Barrett, Ellycia Ford, Jeff Edwards An air conditioner designed to make those hot dry summer days more bearable. This project is a low cost and effective evaporative cooler that uses water’s latent heat to reduce the temperature of the air and increase the relative humidity of the air to a more comfortable level. Suited for hot dry climates, this cooler is designed for use in Aswan, Egypt, but works in any hot and dry climate. The cooler is lightweight and small enough to transport between rooms in a home. Easy to maintain, this project takes advantage of one of the oldest forms of air conditioning known to society. Our working prototype was constructed with a see through acrylic so that you can see for yourself how the cooling process works. BOOTH 511 BOOTH 508 Parks Explorer Pressure Management in Intra-Hospital Patient Transportation Adam Cornfield, Duncan Pawson, Matthew Hill, Matthew Johnson, Phillip Retzlaff, Steven Stosky Chloe Green, Daniel Stuart, Stephanie Vogt, Victor Tran Low-mobility patients often need to be transported from one facility to another within the Foothills Hospital. This movement requires patients to be transferred between numerous surfaces (bed to stretcher, stretcher to MRI table, etc.). Currently this transfer is facilitated by a simple plastic board, onto which patients are placed and then moved via sliding from one surface to another. Patients may spend upwards of two hours on these boards, which provide no source of pressure relief, and can be very uncomfortable. The Project 12 Team has a design goal of creating a device to mitigate pressure in these intra-hospital transport situations in order to increase patient comfort. The proposed solution is a foam mattress with a non-porous cover that will attach to the current transfer board. This mattress will increase patient comfort without overcomplicating or significantly altering the patient transfer process. BOOTH 509 Wii-Hab Brian Pansky, Courtney Duggan, Kent Le, Yin Zhu When working with patients with spinal injuries, therapists routinely work on upper extremity function and strength. In order to make the strengthening exercises more engaging and fun the therapists have tried to use a Wii to play games. The goal of this project is to create an interface that is compatible with both the Wii and the limited dexterity, grip strength, and power of the patients’ movements. Our design allows the patients to successfully play Wii games, improve the strength and control in their elbow and neck, broaden their range of motion and therefore allow them to gain confidence. 2015 Capstone Design Fair It is difficult for traditional wheelchairs to operate throughout the rough terrain of Alberta’s hiking trails. This excludes a large group from hiking, a past-time many Albertans take for granted. The Parks Explorer, an important piece of the Alberta Parks Inclusion Plan, is a project that will open up Alberta’s world-class hiking trails to those with lower-body disabilities. The recumbent tricycle design provides greater stability and control, allowing users to comfortably ascend provincial trails. The drive, braking, tilting, and steering systems are incorporated into the handle bars, allowing the trike to be operated without lower-body movement. Key to the design was creating a user experience that was easy to learn, comfortable to use, and universal for all levels of athleticism and disability. Ultimately, the Parks Explorer is a vehicle of inclusion, enjoyment, and empowerment. BOOTH 512 Flow Rate Control of Water Filters for Balancing Water Quality and Usability Andrew Diec, Hairu Liu, JunYi (Larissa) Zhang, Robert Crane, Sandeep Sidhu, Xingi The bio-sand filters are used in developing countries for providing drinkable water in households. The bio-sand filters function best at lower flow rates. The purpose of this project to design a flow rate controller for a version 10 bio-sand water filter for Centre for Affordable Water and Sanitation Technologies (CAWST). The main function of this flow rate controller is to reduce the initial peak flow rate of the water in the bio-sand filter in order to increase the quality. The objective of the project is to design a mechanical device as an add-on system to the existing bio-sand that will reduce and control the initial flow rate. The design has to be safe, simple to use, attractive, marketable, and built from locally available materials. 22 Mechanical & Manufacturing Engineering BOOTH 513 BOOTH 516 Improving the Portability and Durability of Biosand Filters Adrian Miranda, Haider Kirmani, Kevin Fielding, Phillip Spanswick, Sebastian-Adrian Alexandru, Tara Gholami This project was sponsored by the Center for Affordable Water and Sanitary Technology (CAWST), seeking to provide access to clean drinking water to people in developing communities around the globe. One of the chief strategies in bringing this vision to reality is providing families with Biosand Filters. Currently, a huge percentage of these filters are made of concrete because it is a relatively cheap option that can be made anywhere, potentially by people with no prior technical skill. Despite these important advantages, the concrete filters are extremely heavy and frequently break during transportation. To remedy these challenges, our team has developed a Biosand Filter prototype made primarily out of sheet metal, drastically reducing weight. Additionally, this model can be easily assembled on site and uses nonbrittle parts to eliminate the risk of damage or failure during transportation. BOOTH 514 Manufacturing Process for the Biosand Water Filter Kohl Lounsbury, Konrad Kasprzyk, Max Lee, Oana Cantacioiu, Sam Yoo Biosand filters are used in developing countries to provide clean drinking water. The household filters are constructed by means of batch process using locally available resources. The goal of the project is to improve the manufacturing process using affordable tools and easier manufacturing methods. The filter casing was chosen to be the main focus, specifically, more effective ways to settle the concrete while decreasing time and labour effort. Two main solutions were developed to improve the concrete settling process. The first design is an attachment for a concrete vibrator. In cases where no electricity is available, a second manual solution is a flywheel mechanism powered by a bicycle. Both prototypes provide a less labour intensive and time effective method of settling the concrete, which is ideal for a batch process. The Mech-Winder: Retractable Waterski & Wakeboard Rope Housing Brett Ladick, Gillian Bruce, Graham Dunn, Michael Martinovich, Scott Lalonde, Suzanne Listoe When waterskiing or wakeboarding it is a constant struggle to keep the watersport rope untangled and out of the passenger’s way, but still easily accessible. Our project was to design and prototype a safe, compact and lightweight device that addresses these concerns and mounts onto a variety of different boats. Our design retracts the watersport rope and keeps it untangled and out of the way until it is needed for use, when it can be extracted by pulling on the rope handle. It also allows for the exchange of watersport ropes and easy rope length adjustment, which both depend on rider preference. Lastly, the device has been designed to withstand forces created during watersports and sustain wear from natural elements, such as sunlight and water. BOOTH 517 Assembly Test Stand for Hydraulic Actuators of Oil Rigs Alison McKenny, Carolyn Cepuch, Chad Maag, Dimitrije Protic, Fabricio Romero, Varun Sharma The sponsor of this project, MECHALTA, designs and constructs hydraulic actuators, which are rotary mechanisms that control the flow of mud through oil rig drill strings. These actuators are placed below the top drive and act as a “switch” to open and close the valve that controls the flow of mud during drilling. MECHALTA requires a test stand in their facility to test and showcase their actuators for potential and existing clients. Therefore, our group designed and built a test stand that simulates the rotation of a top drive. This project serves to advertise MECHALTA’s products in the future, and to test the rotating and actuating aspects of each finished actuator. BOOTH 515 Retrofitable Autoflush Device for Tank-Style Toilets Devon Glover, Karam Ahluwalia, Laree Block, Megan Leslie, Yawei Xiao Toilets are something we use every day and are an excellent breeding ground for bacteria. Our project focuses on finding a way to decrease the potential of cross-contamination when flushing a toilet. Our goal is to develop an improved retrofittable autoflush system for tank-style toilets. This design was created by a team in the previous year for their design project and our task is to create an improved design. This will allow the customer to flush their toilet without having to physically touch anything, greatly reducing the chance of coming in contact with foreign bacteria, as well as making everyday life a little easier. People that would be interested in our project include our sponsor, advisor, professor, teaching assistant, and members of the general public, such as home owners, apartment complex owners, and hotel managers. 2015 Capstone Design Fair 23 Mechanical & Manufacturing Engineering BOOTH 518 BOOTH 521 Solar Panel Mounting Mechanism with Orientation Detection Adam Stosky, Andrew Mancini, Chris MacDonald, Kevin Sas, Marc Russel, Zeeshan Ahmed Solar Energy Systems are playing an ever-increasing role in renewable energy. Capturing the radiation the sun emits is done using solar modules to convert this radiation to electricity. Initially, the concept of capturing solar radiation was done by means of a stationary module to be aimed at the sun's path. The problem with this technique is that as the sun moves across the sky, the level of radiation that can be captured is lowered due to the sun being at optimal angle only briefly each day. The goal of this project is to design a device that can track and follow the sun as it moves to maximize the radiation the solar module can capture. Once tested, the information gathered will allow for a contrast to be made between the effectiveness of stationary commercial devices and moving modules with tracking. BOOTH 519 Motorcycle Seat Design for Women Christine Hughes, Emily Tworek, Monique Sullivan, Susan Trinh, Vachan Dhillon The majority of motorcycles available today are designed for and marketed to male riders, and as a result, female riders often find the ergonomics to be uncomfortable and ill-suited to their body size and shape. Torch is a new company that aims to reinvent the motorcycle experience for women by creating motorcycles that are uniquely customized for the female rider. The design team chose to focus on the motorcycle saddle as a starting point for the motorcycle design as it is central to the riding experience. Anthropometric data was collected and analyzed to create a new saddle that increases safety and comfort for female riders. BOOTH 520 JCI Sheet Metal Manufacturing Station Adrien Dechaine, Alberto Trejo, Andres Noboa, Andres Peluso, Lawrence Kong, Matthew Nesselbeck Sponsored by Jonell Canada Inc. (JCI), this project seeks to develop a manufacturing process for structured packing, which is typically used in mass transfer applications. This project focuses on exploring different sheet metal manufacturing techniques in order to determine a suitable process for this application. Structured packing is manufactured from extremely thin sheet metal and is designed to incorporate features such as perforations, corrugations, and dimples. The objective of this project is to design a manufacturing process that focuses specifically on forming dimples and corrugations onto the raw work material with the least amount of flaws while optimizing consistency, and efficiency. The work material is a 0.004” thick 316L stainless steel sheet. Process evaluation was done through physical testing using small scale simulations under varying conditions, and computer simulations with ANSYS structural mechanics software. BOOTH 522 FLOCO Test Stand Upgrading Bradley Seaman, Cory Charron, Dushyant Puri, Isawm Hammoud, Melissa Lam, Rui Ning Li Cameron Measurement Systems, requires a mechanism to allow for the safe transportation and loading of large FLOCO Meters, weighing up to 120lbs during the fabrication process. The current process implemented at the facility requires two technicians to share the lifting of all objects over 50lbs, which is dictated by OHS Code (Occupational Health and Safety). The design was required to be compatible with the pre-existing equipment: the assembly table, calibration stand, and hydro-test stand; each of which possess a unique challenge. Decomposition of the design allowed for simple mechanisms to be installed resolving issues at respective stands. Our design solution consists of a caddy with cam followers to facilitate the translational and rotational movement of the meter, that coupled with minor modifications to the existing equipment allow for the process to be carried out by only one technician. Fatigue Testing of Glass Fiber Reinforcement in Composite Pipelines Ahmed Rasool, Cory Purdy, Harold Lau, John Kim, Musaab Yaqub, Raza Anees Flexpipe Systems is a leading manufacturer and distributor of flexible, composite pipeline solutions for use in the energy industry. Their products are designed to be corrosion resistant and flexible while used in highpressure applications. This is accomplished through reinforcing the thermoplastic pipe with a layer of high-strength material, such as steel-cord or fiber glass. It was found that severe fluctuations of internal pressure reduced the expected lifespan of the fiber glass product. To further their understanding of this fiber glass fatigue problem, Flexpipe Systems has sponsored this Capstone Design project to develop an apparatus that simulates the effect of severe pressure cycling on test fibers. The result is a machine that uses a reciprocating piston to cycle pressure within a fiberwrapped, flexible bladder, and is intended for use in material evaluation and comparison. 2015 Capstone Design Fair BOOTH 523 Automated Pigging (Sender and Receiver) Dylan Gareau, Eric Evenson, Jen Moravec, Parminder Mand, Rebekah Dyckerhoff, Robel Palazzi This project involves the design of an automated pig sender and receiver for a 6” pipeline for Pembina Pipeline Corporation. Pipeline pigs are used in the oil and gas industry to clean the interior walls of pipelines as well as provide a barrier between different types of fluid during batching. There are currently some designs available in the market however they do not meet Pembina’s requirements for operability and cost. The purpose of automated pigging is to increase safety and reduce the operational cost of manually sending pigs, especially for stations in remote locations. Our design enables twelve pipeline pigs to be stored and sequentially launched into the pipeline using automatic valves and actuated pins. At the receiving end, the pigs are stored in hot operation and are able to be easily extracted by the operator with a removable grate. 24 Mechanical & Manufacturing Engineering BOOTH 524 BOOTH 527 DRESSFRESH – A Fully Automated Garment Refresh System Armando Borjas, Churchill Oseghale, Daniel Chan, Maria Shmerko, Rachel Manzano, Todd Rolfson Washing clothes after a single day’s use is a waste of time, money, and energy. Most of the time, the garment is not dirty and simply needs to be refreshed. With the push of a button, the DRESSFRESH system aims to remove wrinkles and eliminate odour-causing bacteria from lightly worn clothes using a mixture of steam, heat, and air. The design of DRESSFRESH was sponsored by aspiring entrepreneur – Aram Razouki – and completed as a joint venture between the Mechanical and Electrical teams. While the Electrical Team is responsible for the electrical components and controls of the system, the Mechanical Team is focused on designing and building the housing unit to incorporate key components. Our housing unit is also designed to withstand the stresses and strains of the refreshing process while also being modestly sized and lightweight. BOOTH 525 Redesign Of A Ski And Snowboard Vise Cody Edwards, Lin Bu Zhe, Robert Wong, Scott Kosasih For this project, an existing ski and snowboard vise is being redesigned in order to eliminate some of the existing issues in order to create a more streamline and marketable product. The purpose of the vise is to clamp skis and snowboards in place in order to perform maintenance on the boards. The focus of the redesign will be on the following issues: failure of the metal guide rods due to fatigue, the vise jaws binding when being closed, the rubber grips that hold the ski/snowboard in place fall off, the clip ring that keeps the threaded rod centered wears quickly and leads to excessive play in clamp, and lastly, creating a vise with a simpler design in order to ensure jaws touch when closed completely. Sensor Arm Design Bo Feng, Evan D’Altorio, Gregary Groeneveld, Matthew Hall, Parsa Samavati, Suraj Jhuty Pipeline Inspection Gauges (PIGs) are electronic and mechanical tools which travel through thousands of kilometers of pipe to determine its integrity, while ensuring the safety of operators. “Smart PIGs” use sensors to detect anomalies along the pipeline during inspection. A widely used method detects corrosion and defects with magnetic fields and sensors. The sensors are mounted to arms, which through some mechanism maintain the sensors in contact with the pipe wall, even when deflected by turns or anomalies in the pipe. The focus of this project is to re-design this sensor arm to allow greater deflection and reduce complex components. With these objectives, the new sensor arm deign aims to increase the dependability and reduce the cost of operation. BOOTH 528 Redline Gap Sub Alex Warthe, Arvin Silva, Harold Schmit, Mark Elliott, Yusra Hemed Pacesetter’s Electromagnetic Measurement While Drilling (EM MWD) tool is used while directional drilling to send locational and directional information from the drill to the surface in order to steer the drill. The Redline Gap Sub provides an electrically insulated gap in the drill string to allow the EM MWD tool to transmit an electromagnetic signal through the ground formation to the surface. As well as being electrically insulating, Pacesetter requires the gap sub to be durable in order to reliably perform in the strenuous downhole environment while withstanding large tensile and torsional forces from the drill string. The gap sub consists of two pieces of drill pipe connected with an electrically insulating material. Our design features a custom threaded connection to maximize strength and a durable epoxy resin gap in between the threads for insulation. BOOTH 526 Downhole Cementing Unit Optimization Akram Ali Al-Mawern, Brandon Nelson, Hoeun Jang, Jeremy Roles, Nicholas Benham, Nik Mouwen In an effort to reduce wasted product and increase the versatility of its oilfield downhole cementing fleet, Magnum Cementing Services wishes to design a system capable of blending a diverse range of powdered additives into dry cement in the field. This system must be designed to blend these additives accurately, consistently, and ‘on-the-fly’. The new equipment is designed to be installed on Magnums existing cement hauling trailers. It will add powdered additives to water using an eductor and dry additive feed system. This water containing “pre-hydrated” additives will then be added to dry cement using Magnums existing system. The design will allow the blends to be changed during a cementing job and means that no extra trucks or personnel will be needed in the field to operate this system. 2015 Capstone Design Fair 25
