5G NRWill Brandt, Marshall Bruner, John Crowell, Foley StokesProject Video linkPDF linkDepartment of Electrical and Computer EngineeringV. ChandrasekarSteve Narcisso, Chuck DueyAs the global sharing of data continues in an ever-growing trend, the need for technology capable of keeping up and providing faster rates of communication becomes an increasingly pressing matter. 5G is a new generation of mobile network technology capable of providing significantly faster data speeds. As almost all have experienced the often slow data speeds of the current 4g LTE communication system, it is obvious why we need greater data speeds for the countless applications involving mobile data. What separates 5G from the current 4g LTE technology is significant gains in both speed and bandwidth. While there are many technologies encompassed in implementing a 5G system, the most notable is the higher frequency of the signal. 5G will implement a millimeter wave which is a much higher frequency wave that presents its own unique challenges. These challenges include a more involved process for mixing baseband signals into and back out of the 1800 MHz n3 band.  
Advanced Extruder Head DevelopmentJosefina Belay, Jason SayreProject Video linkPDF linkDepartment of Mechanical EngineeringDon RadfordComposite Materials, Manufacture and Structures (CMMS) Lab The Advanced Extruder Head project advances the development of 3D printing composite materials. There is a need in the composites industry to improve continuous fiber placement for continuous fiber thermoplastic matrix composites. Composite materials typically require a manual lay-up and/or mixture of solid material (fiber) and the liquid/resin material (matrix), followed by a curing process to solidify the composite. This traditional manufacturing process is time and labor consuming and poses limitations to part geometry. 3D printing improves the composite manufacturing process through higher levels of customization, diminished labor and process costs, and scalability. The expected cost of this project is $1000. The Colorado State University Composite Materials, Manufacture and Structures (CMMS) Lab has allocated funding towards this project. Progress from this project will support the group’s larger efforts to develop a successful composite material 3D printing robot. This team focused its efforts on a feedback system for the advanced extruder which monitors important factors of the printing process; temperature, pressure, and tow width. The team also developed mechanisms to control interlayer fusion as well as consolidation. The final product will be an advanced extruder head capable of thermal, pressure, and tow width monitoring to further supplement print quality.

Insulin is one of the oldest biologics—with the first commercial production dating back to 1921. And yet diabetic patients in the United States face prices for the drug ten times higher than in other developed countries. This criminal pricing has many root causes, not the least of which are: 1) the existence of a near monopoly on its production by three companies, and 2) a vulnerable population willing (or having no choice but) to pay high prices. Among the solutions proposed by a doctor at the Mayo clinic is the establishment of a nonprofit entity to manufacture insulin. Our team is designing a commercial process for production of out-of-patent insulin analogs that could be used by such a nonprofit company. The process will use genetically engineered organisms to express human insulin analogs. It will also include subsequent steps for recovery and purification of the product. Based on our design, we will evaluate the capital and operating costs of the system in order to arrive at a base cost for providing insulin.

Design aspects completed by the team include the structural design, mix design, form design and aesthetic design. The canoe must span between 18 - 22 feet. It must also be able to float and carry a maximum load of four paddlers for the racing portion of our competition.
Back to the future—Breweries as a source of industrial chemicalsIan Lea, Robert Morgan, Paula Mendoza Moreno, Jack MieraProject Video linkPDF linkDepartment of Chemical and Biological Engineering John Sheehan, Courtney Jahn, Ken ReardonThe Acetone-Butanol-Ethanol (ABE) fermentation process is one of the earliest industrial chemical processes developed and implemented on a large scale. During World Wars I and II, the ABE fermentation supported the production of synthetic rubber, which was vital to the war efforts. It was originally pioneered to produce butanol from biological sources and it was later discovered that acetone could also be produced by the same fermentation process. Another important discovery surrounding ABE fermentation was the isolation of Clostridium acetobutylicum, the strain of bacteria used still today for ABE fermentation. After World War II, the ABE fermentation process was displaced by petroleum-based production systems which were far less expensive to operate. In a world now concerned about both climate change and energy security, we may soon find ourselves going back to the future—producing these three industrial chemicals via fermentation of renewable biomass sugars. In this project, we take a second look at the ABE process in the light of these new concerns. We consider technical, economic and environmental aspects, all of which may influence the price and future demand for biologically derived chemicals.
Berthoud Water Treatment Taste and Odor MitigationCasey Corbin, Natalie Oliveira, Cathelyne Powers, Gabriel Rodriguez, Zakri Siegel, Ben Sinnett, Sean SullivanProject Video linkPDF linkDepartment of Civil & Environmental EngineeringThornton, MichalosJonathan Reed, CDM SmithDuring warm weather months, many reservoirs including Berthoud Reservoir experience a large increase in the growth of algae and bacteria. This increase in both algae and bacteria can lead to the formation of unwanted taste and odor causing compounds. Although these compounds are not harmful to human health, if the water is left untreated it will have an unpleasant taste and smell, so the Town of Berthoud has requested a solution to control and eliminate taste and odor issues. 
Biomedical Sciences Diseased Animal Activity MonitoringJacqueline Clark, Kayla Hackett, Hannah Hindie, Sean MulvihillProject Video linkPDF linkBiomedical SciencesAngela Bosco-Lauth, Richard Bowen, Bonnie RobertsBiomedical SciencesCOVID-19 research is critical during the current pandemic. Looking to better understand the disease and to create vaccines and therapeutics, the need for viral research in rodents has increased. Hamsters are a good model for COVID-19 research because the disease affects them in a way similar to humans. However, hamsters are difficult to observe due to their nocturnal nature, stoic tendencies, and change in behavior with human interaction. This causes current low-cost methods to provide unreliable and subjective data. While there are accurate methods of studying rodent activity, they are not cost-effective and can range from $4,000 to $5,000 for one device making them unrealistic options as hundreds of cages need to be simultaneously monitored. Therefore, this Hamster Team, a team of mechanical engineers, is creating a low-cost device that automatically measures the overall activity levels of rodents in a cage and returns that data to the researchers in a useful manner. Our device will make the research more financially feasible while providing objective, reliable data. Come visit us these E-days to learn more about our infrared break-beam data acquisition system, our sealed custom casing, and the behind-the-scenes work done to bring this device to life!
Booster Station/WMF DesignDixie Poteet, Jack Marvel, Ryan Hunt, Dylan Lektorich, Harrison McKittrick, Troy MontagueProject Video linkPDF linkDepartment of Civil & Environmental EngineeringChristopher Thornton, Christopher MichalosMs. Elie Chavez CDPHE Permit Engineer, Ms. Rachel Frisz CPHE Permit EngineerColoState Gas Processing, Inc. has been approved by the Colorado Oil and Gas Conservation Commission (COGCC) to drill four new wells in the Piceance Basin, located in the Western Slope of Colorado. In preparation for this new project, Colorado Greens Engineering was tasked with preparing an air permit application and designing a water management facility and booster and gas station on behalf of ColoState Gas Processing, Inc. An air permit application must be prepared in accordance with the Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division (APCD) guidelines prior to construction beginning. The booster station will compress natural gas produced by the wells for transportation while the water management facility will upgrade the produced water for reuse in hydraulic fracturing operations. Additional project efforts include researching water treatment technologies for use in the water management facility, developing a process simulation model for the booster station, sizing conveyance lines, and calculating the cost estimate over a thirty-year design life. Colorado Greens Engineering is committed to delivering safe and economically feasible designs for this oil and gas project.

N/AThe Brumadinho Tailings Dam What-If design project involves analyzing the failed Feijão Dam I, and proposing engineered alternatives to prevent such failure if given one year notice prior to failure. The “What-If” design allows for lessons to be learned from the already failed system and be applied to future dams facing similar or even identical structural, geotechnical, and stability problems. Three alternatives, including concrete piles, stabilization berms, and a drainage system were proposed to the sponsors. A long term remedy was also proposed to add to any of the alternatives, which was a cover system. The project was proposed in a two-tier fashion regarding depth and technical concepts in information to target both the project sponsors and certified engineers, as well as the general public in a more broad sense to help gain public acceptance for the work to be complete.
Canine ExoskeletonKevin Alamo-Perez, Dominic Castillo, Joanna Dunne, Brooke Landoch, Bradley Rauch, Andrew ReeseProject Video linkPDF linkDepartment of Electrical and Computer EngineeringAnura JayasumanaMany large canine breeds suffer from degenerative myelopathy (DM). DM is a progressive disease that causes degeneration of the spinal cord and can lead to partial or total paralysis of the hind legs. To date there is no cure for the disease and no surgical intervention methods that can alleviate symptoms. However, the use of a brace is one method that can help. To overcome the rehabilitation limitations for these canines, an electro-mechanical orthopedic brace system has been developed to assist with the recovery of injured or partially paralyzed dogs.  The canine exoskeleton team, in collaboration with the CSU Veterinary Teaching Hospital, has implemented solutions to current rehabilitation methods.  
Caterpillar Super Knock RCM StudyMichael Lauch, Mason Reinick, Zack Swartwout, Shozab ZaidiProject Video linkPDF linkDepartment of Mechanical EngineeringAnthony MarcheseCAT, Dr. Dave MontgomeryThis project involves studying a phenomenon in natural gas engines called super knock. Super knock is caused by oil droplets escaping the crankcase and entering into the combustion chamber. This creates a rich area in the chamber which causes the fuel to auto-ignite. Auto-ignition spikes internal chamber pressures and can cause severe engine damage. The goal of this project is to simulate this phenomenon and study it using a Rapid Compression Machine (RCM). A combustion chamber has been designed with windows in it so we have the ability to observe the combustion. A droplet generator injects engine oil into the chamber and a laser ignites it. The current senior design team is working on a new combustion chamber, focusing on improving the viewing area of the windows. We are also working on a Matlab code that has the ability to track the oil droplet through the chamber and measure its size and velocity. We are also working on an ANSYS model which will allow us to simulate the temperatures experienced on the chamber and surrounding components

Centrifugal Compressor and Expander for SOFC/IC SystemRustin JensenNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Todd BandhauerFuel cell technology has seen large improvements in feasibility. In some fuel cell applications, pressurizing the fuel cell allows for higher power and lower temperatures within the cell. This pressurization requires a compressor. The efficiency of the system depends on the efficiency of the compressor system. One such application of a pressurized fuel cell that has been under development is using a solid oxide fuel cell (SOFC) in conjunction with an internal combustion (IC) engine as an electric generator. This project focused on developing a high efficiency centrifugal compressor and expander system that would sufficiently meet the efficiency and pressure requirements for a SOFC/IC system. Various compressor and expander configurations were modeled, the most suitable configuration was selected, and a test bench was designed to study the performance of the selected configuration. The test bench was assembled, with testing currently underway.
Claymore Dam Hazard Classification and DesignReed Featherstone, Cassidy McCarthy, Brenna Allison, Mateo Rivera, Matt Bullock, Matthew BlumensheinProject Video linkPDF linkDepartment of Civil & Environmental EngineeringChristopher ThorntonKallie Bauer, Colorado Dam SafetyRamDamSolutions has been working on Claymore Dam to assess the integrity of the lake as a whole. There has been a significant passage of time since Claymore Dam was last analyzed, and new hazard classification guidelines were produced by Colorado Dam Safety in 2019. The project scope includes dam remediation and a hazard classification. The hazard classification was completed and assisted the development of alternative design elements used in the dam remediation. The dam elements studied for alternative design included the spillway, inlet structure, and dam embankment.
Clearing the air—Direct capture of CO2 from the atmosphereKhalid Alanazi, Salem Badahdah, Bethany King, Roman Plano, Emily Ratdke, Tyler SweetProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanIn 2019, approximately 40 billion tons of carbon dioxide were released into the atmosphere, and that value has been increasing exponentially since the 1950s. High levels of carbon dioxide being released into the atmosphere have led to an increase in Earth’s surface temperature, which has many catastrophic effects on the global climate. Many companies are implementing policies to reduce their carbon dioxide emissions, but not enough. Nor is emission reduction alone enough. The increasingly imminent threat of catastrophic climate changes may require human society to remove greenhouse gases already in the atmosphere. The goal of this project is to design a process for quickly and efficiently pulling carbon dioxide directly out of the air—not an easy trick, considering the “low” concentrations of CO2 in the atmosphere, from the point of view of chemical process engineers. Our design incorporates recent research on technologies that absorb and concentrate atmospheric CO2, which can then be stored (a process called sequestration) or recycled to produce new products. Our challenge is to design a process that is affordable and sustainable.
CO2 Capture - Chemical AbsorptionNames: Bassam Alabbad, Abdulrahman Alabede, Abdulkarim Aldhafeeri, Aziz Alzneidi, Ali BukhedherProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanThe City of Fort Collins has set a goal to be carbon neutral by 2050. And yet Fort Collins and much of the surrounding area of northern Colorado will rely on coal to produce almost 40% of its electricity this year at the Rawhide Unit 1 generating station operated by the Poudre River Power Authority. Each year, the Rawhide unit dumps around 2 million tons of CO2 into the atmosphere. Advocates for clean coal have promoted technology known as Carbon Capture and Sequestration (CCS) as a way to reduce the contribution of CO2 to the atmosphere from coal-fired power stations like Rawhide. We are one of two teams evaluating the effectiveness of technologies that can capture the CO2 from Rawhide’s smokestack. We are focused on the use of well-established technology which uses chemical absorption to remove the CO2. In our design, the CO2 is further concentrated, so that it can be sequestered (stored) underground. Using chemical engineering principles, we will evaluate the cost and efficiency of this technology.

Composite Tubes and Pressure Vessel developmentEthan Anspach, Aidan HughesProject Video linkPDF linkDepartment of Mechanical EngineeringMostafa YourdkaniMultifunctional Polymers and Composites LaboratoryThis project aims to greatly reduce the manufacturing time of composites produced in the filament winding process. Traditionally, composites produced in the filament winding process are manufactured by passing filament through a resin or epoxy then wrapping it around a rotating profile called a mandrel until desired thickness is reached, followed by a secondary curing process for several hours inside an autoclave. The autoclave curing process is a large part of why composites are only used in high end applications because the large amount of time and energy needed to create a single composite part make these materials unfeasible for any very large scale manufacturing. This project will remove the lengthy secondary cure process by utilizing a self propagating curing reaction called frontal polymerization to cure the part without needing to even remove the part from the mandrel. This reaction will be induced by several energy sources, including resistively heating the mandrel and ceramic infrared heat lamps. The process demonstrated by this project has potential to make composites more feasible for a variety of applications
Computational Modeling of SARS-CoV-2 Infection in HumansPatrick Charlton, Hannah Mabry, Stuart McKnight, Trevor WoodruffProject Video linkPDF linkSchool of Biomedical Engineering, Department of Chemical & Biological EngineeringAshok PrasadA computational model of the processes involved in the infection of human lung epithelial cells by the SARS-CoV-2 virus. The model uses a large system of ordinary differential equations, based on chemical kinetics of infection steps, to determine the concentration of important proteins throughout the course of the infection. Important proteins involved with viral entry, viral replication, host immune response, host immune suppression, and viral release, can all be tracked throughout the course of the infection. Users will have the ability to manipulate individual steps in the infection process to simulate how different drugs and disease states may affect the progression of the infection.

Course RoverConnor Cloherty, Tomas Martinez, Greg Spaulding, Trent WeldonProject Video linkPDF linkDepartment of Mechanical EngineeringJohn PetroWSCOEThe Course Rover is the contemporary Sunday bag for novice to intermediate golfers who are looking to play casual golf and invest minimal time and money in their game. Instead of hoisting an entire club set over their shoulder and paying hundreds of dollars to do it, the Course Rover gives players a lightweight, rolling golf bag that carries all of the tools and accessories they would need on a shorter, easier course. The Rover started as two mailing tubes duct taped together, one to hold a few golf clubs and one to hold a water bottle or a couple canned drinks. It now uses 3D printed components to house a set of wheels, a drink elevator system and other features. The Course Rover is a customizable and modular product that can be almost completely manufactured with a 3D printer
Critical Optical Components for LasersMalek Aleshekh, Cole Glaser, Hayden Miltersen, Kevin Novak, Bryan SullivanProject Video linkPDF linkDepartment of Electrical and Computer EngineeringCarmen MenoniThe aim of this project is to design and manufacture a compact, semi-portable, optical testbed to assess laser performance of optical thin film coatings, also known as the laser induced damage threshold (LIDT). The testbed will be integrated with motors to precisely control linear motion of critical optical components that allows automation of the sample testing via graphical user interface (GUI) on a computer. This interface will also record the fluence of the laser, the beam profile, and a magnified image of the test site.
CSU ATRColin Hice, Jason KiehlbauchProject Video linkPDF linkDepartment of Electrical and Computer EngineeringBranislav NotarosThe CSU Antenna Test Range or 'ATR' began in 2008 as a multi-disciplinary project. Since then, multiple senior design teams have worked on it. The ATR is nearing completion, and in its final form will be an automated antenna characterization system that will have both modeling and measurement capabilities for near and far fields from 7-18 GHz. The main instrument utilizes an anechoic chamber inside the Colorado State University Electromagnetics Lab. This system integrates disciplines from electromagnetic waves and radiation, computer science, control systems, power systems, and circuit theory.
CSU BreweryIan Danas, Teddy KlovstadProject Video linkPDF linkDepartment of Electrical and Computer EngineeringTony MaciejewskiJeff Callaway, Olivera NotarosThis project will focus mainly on the automation of the brewing systems inside of the RamSkeller brewery. There will be a focus on the improvement and continuation of previous years' work as well as work on new systems. The goal of the project for this semester is to automate the Mash Mixer process as well as help fix any physical systems that might be malfunctioning within the brewery. The team will be practicing creating the functional documents necessary to streamline and record how the automation needs to be done so we can then turn these documents into the sequence manager software that the brewery operates on.
CSU Foothills Campus Stormwater Master PlanTom Anderson, Stephen Driscoll, Michael Perez, Cameron Salz, Taylor Schulze, Palen StreamProject Video linkPDF linkDepartment of Civil & Environmental EngineeringChristopher ThorntonCSU Facilities Management, Susanne Cordery, Fred HaberechtThe CSU Foothills Campus Stormwater Master Plan was last updated in 2002. As of 2021, campus development has led to increased stormwater runoff from the site and raised the need to update the current master plan. The purpose of the update is to address present and future stormwater conditions by designing improvements for detention, drainage, water quality, and erosion control infrastructure on the CSU Foothills Campus. Accordingly, the objective of the update is to develop design solutions grounded in stormwater management best practices that can be effectively incorporated into the existing stormwater management plan. Updating the plan will benefit stakeholders within the CSU community and throughout the City of Fort Collins by helping to manage stormwater runoff, mitigate flood risk, improve erosion control, protect campus infrastructure, preserve habitat value, and minimize impacts to water quality.

After upgrading its northern walls, the ERC needs a structure to shield its facility from the elements. Colorado winters can be very cold, making outdoor testing a miserable undertaking. Enclosing this testing facility inside will allow for longer testing periods and protect fragile models.
CSU Mountain Campus Fire Protection SystemStephen Agenbroad, Paige Genaula, Trey Seyers, Lukas Garcia, Timothy Osborn, Allison MaddocksProject Video linkPDF linkDepartment of Civil & Environmental EngineeringChris ThorntonSusanne Cordery, Environmental EngineerThe Colorado State University mountain campus is a remote satellite facility of the main Fort Collins campus. The campus is host to students, researchers and tourists. Recently, the campus was a host to a string of wildland firefighters. The Cameron peak fire started August 13th, 2020 in the northern region of Colorado. It spread over 208,913 acres over the Arapaho and Roosevelt National Forests. The CSU mountain campus was located in the fire path. Thankfully the firefighters were able to protect the campus, and prevent it from being burnt down. The goal of our project is to develop a Fire Support System for the campus. This fire support system will provide temporary sprinkler systems, and will also allow the firefighters to integrate with the system. A plan of action will also be drafted, so that firefighters can understand and integrate with the system. The plan will also detail how the campus will prepare for the fire such as fuel reduction, temporary sprinkler set up, and many other safety measures.

The campus is a site for student learning, workshops, retreats, conferences, and meetings. Colorado State University prides itself on being sustainable and not harming the environment. Providing Colorado State University’s Mountain Campus with a source of renewable energy through hydropower is the objective of this project. Hydropower is a clean source of energy that can provide CSU with renewable energy for years to come.
Customized 3D Printed COVID MasksAbdulaziz Abuhaimed, Ferass Aljaber, Ahmad Esmat, Alyssa ShepherdProject Video linkPDF linkDepartment of Mechanical EngineeringDavid PrawelWSCOEThe demand for masks have drastically increased in the last year due to the rapid growth and spread of the Coronavirus (COVID-19) in the United States. An important question we must ask ourselves is, how effective and efficient are the masks that are commonly used today? A cloth/surgical mask is only about 40 percent efficient due to leaks around the nose and under the chin. The goal of our project is to design and manufacture (through 3D printing) a respirator mask that is comparable to the N95 in terms of efficiency, as well as increase the “effectiveness” by providing a sealed fit around the face. This is done by customizing the masks to the customers' facial dimensions through image analysis. Measurements from the customer’s face are used to scale the “base” SolidWorks file which results in a sealed fit from the nose to the chin, thereby increasing the effectiveness. The team then 3D prints all components of the mask, assembles and delivers the mask to the customer(s). The masks are tested at CSU's Center for Energy Development and Health (CEDH) Lab to ensure that they are both effective and safe to use
Cybersecurity for Vehicles: Network Anomaly DetectionDavid Rohrbaugh, Andy WorcesterProject Video linkPDF linkDepartment of Electrical and Computer EngineeringSudeep PasrichaUnlike many Senior Design projects, the main result of this project is not physical. Rather, it is a machine learning model. Within the depths of Machine Learning, we implemented a Neural Network/Deep Learning algorithm that can accurately detect unusual behavior in the normal flow of information. The normal flow of information is communication between embedded system sensors in  vehicles through the CAN bus. When the flow of information is disrupted, there could be unusual information being detected, a failure in the system, or a direct cyber-attack on the system from the outside. We implemented an algorithm that achieves the performance necessary to be able to reliably detect attacks by finding this unusual behavior. We used Keras with TensorFlow in the Python programming language to implement this. After researching available options for our algorithm, designing an algorithm, and then training and testing against data, we were then able to see if it worked according to a set of standards as a part of the design process. We also researched related aspects of our project, for example, how it would be implemented practically.
Data Center Power Conservation Through Return Jet Impingment Server CoolingRoman YoderNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Todd BandhauerIn recent years, improvements in power usage effectiveness (PUE) for data centers have stalled as conventional cooling methods are limited. PUE quantifies the amount of additional power (cooling power, lights, etc.) a data center requires over computational output. Return jet impingement cooling demonstrates a potential solution to improve the PUE metric by providing high heat flux cooling at ambient conditions and low flow rates. Comparing collected data for a baseline server to that of an equivalent system using a return jet impingement device allows a direct performance comparison and demonstrates the degree of improved PUE. Traditionally PUE is calculated by considering each server as a purely computational load; onboard server measurements facilitate a new high-resolution category 5 PUE metric accounting for individual server’s onboard fan power. The ideal pumping power of return jet impingement alone is 10% of the consumed onboard fan power for traditional server operation; this coupled with reduction in air conditioning load creates a competitive PUE metric. This results in identical computational output for a significant reduction in data center power consumption.
Deep Reinforcement Learning in FEA Driven Virtual Environments for Control of Flexible RoboticsSebastian MettesNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Steve SimskeHigh precision robotics traditionally require stiff arm links which can be controlled with simple kinematics. Robots with flexible arm links are difficult to control precisely due to the dynamic nature of link deflection under load. By training a deep reinforcement network to compensate for these deflections, precise control of flexible robotic arms is possible in real time with low-cost controllers. Precise, flexible robotic arms have the potential to decrease the cost of underwater and space robotics by enabling low cost and low density link materials, such as plastic, to replace traditional steel, aluminum, and carbon fiber.
Development of a Chemical Kinetic Model for LPG Combustion Under Engine-like ConditionsColin SluneckaNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Anthony MarcheseLiquefied petroleum gas (LPG) has many properties that make it an attractive alternative fuel such as lower cost than conventional fuels and an established distribution infrastructure. The development of high efficiency, spark ignited LPG engines is currently limited by engine knock and misfire. A rapid compression machine (RCM) was used to characterize the effects of variation in LPG fuel reactivity, equivalence ratio, and exhaust gas recirculation (EGR) on autoignition of LPG/oxidizer/inert/EGR blends. Experiments were conducted with 100% propane (C3H8) and a mixture of propane, propene, ethane, isobutane, and n-butane. EGR was simulated with mixtures of Ar, CO2, CO, and NO at substitution percentages from 0 to 30 mass percent. Equivalence ratio was varied from 0.75 to 1.5. Ignition delay period under homogeneous autoignition conditions was measured at compressed pressures and temperatures of 23 to 25 bar and 701 to 921 K. Zero-dimensional simulations of the RCM experiments were performed using CHEMKIN with several detailed chemical kinetic mechanisms to determine their suitability at predicting ignition delay periods. Multiple reduced chemical kinetic mechanisms were created from the NUIGMech1.1 mechanism to determine the optimal balance between accuracy and computational efficiency for future three-dimensional, time-dependent spark-ignited engine computations.
Development of Advanced Combustion Strategies for Direct Injection Heavy Duty LPG Engines to Achieve Near-Diesel Engine EfficiencyManav SharmaNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Bret WindomInternal combustion engine research focuses on the improvement of fuel economy and the reduction of the tailpipe emissions of CO2 and other regulated pollutants. Direct-injection and alternative fuels such as liquefied petroleum gas are promising solutions. LPG represents a practical and economical solution for fueling the United States’ heavy-duty transportation sector. However, before widespread adoption can occur, energy conversion efficiencies for LPG engines must achieve values comparable to those seen in diesel engine platforms. The overarching goal of the proposed research is to address fundamental limitations to achieving near-diesel efficiencies in heavy duty on-road LPG engines. The proposed project will focus on developing an experimental setup to verify and finely tune DI LPG engine simulation of the injection and mixing process by utilizing a constant volume high pressure spray chamber to study direct LPG fuel injection penetration, vaporization, and mixing. To date, limited information is available regarding the spray dynamics of LPG at engine relevant conditions. On the global market LPG composition can vary dramatically, leading to even more insufficient data. The successful completion of the project will allow future research to use the finely tuned LPG spray model to develop a heavy-duty LPG engine with diesel like efficiency.
Development of Highly Efficient Solid Oxide Fuel Cell (SOFC) Tail Gas EngineThomas MuettertiesNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Bret WindomInitiatives for increasing micro-grid power generation throughout the US have pushed for a need for highly efficient, cost-competitive electricity generation fueled by natural gas (NG). A promising solution is a hybrid pressurized SOFC + internal combustion engine (ICE) system that has the potential to achieve 70+% efficiency at a competitive price of less than $1000/kW. To achieve these targets, an ICE needs to deliver up to 15 kW at a thermal efficiency of 35% fueled off a dilute fuel, containing a fraction of the energy found in NG. To achieve this goal, CSU and Kohler are converting a stock 2-liter diesel to operate on the anode tail gas of the SOFC. A test facility has been set up and baseline diesel data has been collected and used to verify the stock diesel engine in GT-Power modeling software. Using the validated GT-Power model, it was converted to operate on the SOFC tail gas making optimizations to increase engine efficiency. Future work will require gasifying the diesel engine and testing to prove the engine's performance.

ECE OutreachBrandon CrispProject Video linkPDF linkDepartment of Electrical and Computer EngineeringOlivera NotarosThe ECE Outreach team strives to introduce students to electrical and computer engineering through educational demonstrations, workshops, and seminars. Of all of the engineering majors, ECE has sometimes been underrepresented, both in terms of incoming freshmen choosing the major, as well as high school students being aware of the major in general. This project strives to change this by introducing students to the exciting world of electrical and computer engineering. Outreach is split up into three sub teams, the Analog, the Digital/Programming, and the Math team. With each sub team focusing on developing exciting demonstrations and lesson plans related to each team. We then use these demonstrations and lesson plans in events and workshops to get students interested in ECE, as well as helping students within the ECE department.

Energy SuitcaseHunter Becvar, Kyle Cunningham, Joshua Ehr, Sean WilliamsProject Video linkPDF linkDepartment of Electrical and Computer EngineeringJim BarnesSebastian Africano, James Calabaza, Valerie SmallWe live in a world that relies on electricity. Yet there are still so many impoverished and rural areas that don't have a reliable source of power. Even in the United States, there are places where people struggle for this necessity including the Pine Ridge Reservation in South Dakota. Without access to electricity, extreme weather and emergencies can quickly become life-threatening. Trees, Water, & People, our local non-profit collaborator, is working to provide access to affordable, renewable power sources to this community. They have purchased an educational We Share Solar Suitcase from We Care Solar, which includes two small solar panels and DC charging ports. This is a very valuable device, however, it doesn't produce enough power to run small appliances. The goal of this project is to create a portable suitcase that provides 150 Amp-hours to charge a laptop (~.05kWhr) , two phone chargers (~.006kWhr a phone), an LED light (~.005 kWhr), and an insulin refrigerator (~.005kWhr) for 24 hours. This suitcase will be powered by four solar panels. This suitcase has the ability to save lives, and make daily tasks a little easier for those without easy access to electricity.

Extraction of Magnetic Material PropertiesDominic Molinari, Garrett RossProject Video linkPDF linkDepartment of Electrical and Computer EngineeringJim CaleThe goal of this senior design project is to build a testbed with graphical user interface (GUI) to automate the measurement of effects in sample ferrimagnetic materials in deep saturation over a wide range of frequencies, and to characterize their magnetic characteristics using artificial intelligence algorithms. The impetus of this project is to improve on the IEEE standard, so in addition to having application to many industries, it also serves as a possible educational tool.   For deep saturation measurements we will apply utility voltage (120 VCA) through an autotransformer. To test and account for coercivity (conceptually, a materials resistance to magnetization/demagnetization), we will use a grid simulator to set an arbitrary input signal and sweep over a range of frequencies (< 1Hz -50 kHz). We will verify the fitted magnetic characterization functions against high frequency measurements that we will collect using the testbed. Control of the testbed, display of raw and processed measurements, and fitted characteristics will be displayed through our GUI.
Feeding our crops with wind energy: wind energy-derived ammonia fertilizerBlayne Banghart, Sajad Al Hamoud, Joe TallanProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanOne of the biggest issues facing wind power is curtailment—the problem of unused wind power at night (or any time) when available power from wind exceeds demand on the electricity grid that supplies our homes and businesses. One of the biggest problems facing agriculture is the unsustainable use of fossil-based fertilizers—in this case, ammonia. In this project, our team evaluates a scheme for dealing with both problems. Today, ammonia is produced in huge, large scale factories that use natural gas as a feedstock. Our work involves the design of a novel scaled down ammonia fertilizer production process in which ammonia is produced from hydrogen and nitrogen, and the hydrogen is produced via electrolysis of water powered by electricity from wind that would otherwise not be used on the grid. We make use of available data and preliminary design information published by researchers at the University of Minnesota to determine the cost and sustainability of such a process.

Indoor Navigation Using SmartphonesColin Jiang, Jack Lueck, Sam WolynProject Video linkPDF linkDepartment of Electrical and Computer EngineeringSudeep PasrichaIndoor localization is a complicated problem with many possible solutions. Our project attempts to combine two approaches to achieve better accuracy. Dead reckoning is an approach that uses a gyroscope and accelerometer to predict a change in movement. While very useful on a short time scale dead reckoning loses its accuracy as error builds up. Wi-Fi fingerprinting is an approach that uses the existing wireless networks already set up in buildings. It attempts to predict where the user is based on different Wi-Fi signatures in different locations. Wi-Fi fingerprinting is less practical at short time scales due to its high power consumption. We aim to combine these two approaches to minimize their weaknesses and obtain higher indoor localization accuracy.
Integration of Mobile Wind Sensor for Methane Sensing from Oil and Gas InfrastructureBilal KhanNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Azer YalinMethane is a potent greenhouse gas that causes climate change. It has a 20-year global warming potential (GWP20) which is 84 times more than that of CO2. The oil and gas industry is responsible for the majority of methane emissions in the United States. A range of technologies are under development to detect and mitigate these emissions to minimize the adverse effects on human health and the climate. The current research proposes to deliver an economically viable, novel, mobile methane-sensing system with an on-board ultrasonic anemometer that is capable of quantifying methane emissions from data that is gathered through intensive experimental investigations of methane-producing sites. The methane sensor has been under development for several years; the anemometer is a new addition. The objective of the proposed work is to seamlessly integrate the anemometer to the current methane sensing system so that methane emissions can be quantified more accurately. This would make the system more scalable and practical for widespread use since it will not require the setup and maintenance of fixed sensors. The detection from the sensor will allow for preventive measures to be taken which would reduce overall methane emissions into the environment.
investing in the future with sustainable plasticsAlex Benitez, Ryanne Buck, Cody HackerProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanThe majority of plastics currently in use are petroleum based and not sustainable from a global perspective. Research from the National Renewable Energy Lab point to the option of bio-based polymers as a more ecologically efficient basis for plastics. While commercial bioplastics like poly lactic acid typically use microbes that grow on sugar to produce the chemical precursors of the plastic, our team is turning to an unusual class of single-cell microbes called Cyanobacteria. These organisms are neither plants nor bacteria. They are, essentially, bacteria that are capable of photosynthesis—meaning that they can turn sunlight and CO2 in organic biomass. Some strains are also capable of producing polymers known as polyhydroxyalkanoates (PHAs). These polymers can be used to make plastics. The Cyanobacteria are closely related to microalgae and can be grown using similar production schemes. Our team will design a commercial (large) scale production system to making PHAs from sunlight, waste CO2 and other nutrients. The heart of the production process is a photobioreactor capable of efficiently delivering sunlight and CO2. Subsequent steps are required to recover the PHA polymers for further use in plastics production.
John Deere Low Temperature Thermal Cooling LoopShahzeb Chaudhary, Alec DeStefano, Hadley PattersonProject Video linkPDF linkDepartment of Mechanical EngineeringDan Olsen, Don GroveJohn Deere, Dave RobinsonThe John Deere Low Temperature Thermal Cooling Loop (LTCL) senior design project is a one year, top to bottom design process. The primary objective of this project is to design a system to moderate the temperature of various machine components while they undergo testing at John Deere’s headquarters. This objective must be accomplished by a system taking up no more than one cubic meter and capable of coping with environments ranging from -40 to 115 °C. The system is almost entirely automated, requiring only initial interfacing with the test components and a brief system check. From there on the cooling loop can monitor its own pressures and temperatures, adjusting as needed to maintain a constant temperature in the test component.
Larimer County FloodplainKatie Ascough, Theresa Centola, Keian Freshwater, Billy Joel, Justin Rychlick, Kayla Schultz, Brett Van AlstineProject Video linkPDF linkDepartment of Civil & Environmental EngineeringChristopher Thornton, Chris MichalosLarimer County, COThe Northern Colorado region is well-familiarized with past severe flooding events; as such, Larimer County makes an active effort to consider flood planning and infrastructure. The county follows U.S. Federal Emergency Management Agency (FEMA) guidelines to accurately map and assess the risk of flooding for homeowner insurance purposes. However, in many rural parts of Larimer County, existing floodplain maps are not reliable. Using up-to-date hydrological, streamflow, and mapping software, our team will model two county streams: Dry Creek, and a segment of Boxelder Creek. In order to ensure FEMA compliance, areas for improvement will also be identified within each floodplain. Overall, the aim of this project is to create reference documents to be used in future county-related flood planning involving these rural streams.

Manufacturing of Cell-free Rapid COVID-19 testRachel Chayer, Zeus Alcon, Michael KwolkoskiProject Video linkPDF linkDepartment of Chemical and Biological Engineering Christie PeeblesWith the COVID-19 pandemic, rapid testing for the virus has become increasingly important as case numbers change and outbreaks need to be managed. Synthetic biology allows for the rapid testing of individuals using cell-free systems on a paper-based platform without needing complicated laboratory techniques. Within this testing assay are cell machinery components that are freeze-dried onto a disk of paper and cause a color change when certain conditions, such as having viral RNA in a patient’s sample, are met. The ability to manufacture such a testing system requires cell culturing in an industrial scale to obtain necessary cellular components and produce enough tests for it to be a viable option in places without access to laboratories or skilled technicians. Many cells containing the necessary proteins and cellular machinery must be grown in a bioreactor where they have time to produce those materials. From there, the components must be extracted without being destroyed, dried onto a piece of paper, and packaged.

MRI and Orthopedic Healing DiagnosticsNathan Eads, Ross Mccaskey, Yipin SunProject Video linkPDF linkDepartment of Electrical and Computer EngineeringBranislav NotarosCurrent MRI machines have a maximum field strength of 3 T. New MRI scanners are being designed for higher field strengths, resulting in better image resolution and operating speed. The current design of the internal RF coil will no longer be compatible with a higher field strength. Therefore, the RF coil needs to be redesigned to operate in ultra-high field MRI scanners.

The first semester of this project was aimed at rebuilding and optimizing a novel RF coil design. We have replicated a new coil model using the simulation software HFSS, and have performed parametric analyses to optimize the design parameters. The new microstrip model has shown promising improvements in field strength, field uniformity, and inter-element coupling compared to the microstrip model.  

In the Spring semester, we switched our interest to an 8 element array instead of 16. The next step will be to finalize an 8 element RF coil design in HFSS with Teflon support parts added onto the conductor strips. Based on the finalized HFSS design, we will physically build a prototype. Eventually the plan is to have a prototype constructed and tested to provide preliminary results of its performance characteristics.

NASA Robot MiningKyle Ciccarelli, James Henander, Jonathan Jacobson, Jarryd Meyers, Lex Pollicita, Colby Richardson, Alden Truesdale, Connor Worrell, Bin Akmal YeshelProject Video linkPDF linkDepartment of Mechanical EngineeringJianguo ZhaoAllied ElectronicsThe NASA Robot Mining team competes in a NASA sponsored university event to design, build and test a lunar mining robot. The goal of the competition is to autonomously cross over an obstacle zone, dig into moon dust and extract some gravel, and deposit this gravel into a bin. This is the 4th year CSU is competing in this competition. This year the team is working to improve the previous year's design. The robot we designed consists of a metal belt with buckets connected to it that rotate and dig into the ground. These buckets place the moon dust and gravel into a storage tank. The storage tank is made of a mesh to allow the moon dust to fall through and is actuated like a dump truck to deposit the gravel into a bin. The electronics use various sensors to detect obstacles and map a course through the obstacle zone which allows the robot to operate autonomously. 
Natural flightpaths: Turning vegetable oil into jet fuelJames Brown, Jack Burns, Abdulrahman Masoud, Levi RobinsonProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanWhile electric cars may represent the future of personal transportation, and there is a lot of talk about electrifying freight trucks, there is one segment of the transportation market that will always need an energy-dense liquid fuel—aviation. So, finding a substitute for petroleum derived jet fuel is critical to the future sustainability of the aviation sector. Aviation fuels are hydrocarbons consisting of relatively long chains of carbon and hydrogen. The closest equivalent to these molecules in the biological world are the natural or vegetable oils—also known as lipids or triglycerides. In their natural form, they are not quite right for use as a fuel. But the chemistry of converting them into molecules that look exactly like aviation fuel is well understood. Such fuels have already been tested—mostly as 50% blends with their petroleum counterparts—in commercial passenger jets. Bio-based fuels have many advantages compared to petroleum based fuels including their reduced emissions of fossil CO2 and their reliance on renewable raw materials. In this project, we design a commercial (large) scale production process for converting natural oils into jet fuel. Our goal is to assess the cost and technical feasibility of such a commercial operation. The big challenge we face is coming up with a design that is both environmentally friendly and economically competitive.
On-Device ML for SmartphonesCollin Peirce, Cole RiechertProject Video linkPDF linkDepartment of Electrical and Computer EngineeringRyan KimMachine learning (ML) has grown in parallel with the "Big Data Age" as a ubiquitous tool in applications ranging from health to finance to scientific research and beyond. Here, we explore the applications of ML in education, motivated by the idea of a homework auto-grader. Handwritten recognition, sometimes called optical character recognition (OCR), has been a longstanding puzzle in ML. While significant advances have been made in numeric recognition, there are still a number of challenges when decoding handwritten alphabet characters, punctuation, and math symbols. As well as choosing an appropriate network model, ML computations also require considerable processing power. Currently, ML has advanced to the stage where such computations are feasible on desktops and even laptops. However, both industry and academia are introducing ML to smaller devices such as embedded systems and smartphones which are limited by their computational power and available energy consumption. In this project, we intend to explore   the challenges of ML applied to an example in education.

Quatro SocketEmma MacLaughlin, Logan Munson, Avi Nataf, Jack FleischmannProject Video linkPDF linkSchool of Biomedical Engineering, Department of Chemical & Biological Engineering, Department of Mechanical EngineeringKirk McGilvrayQuorum ProstheticsVolume change in the residual limb is a common obstacle amputees face during their use of prosthetics. Quorum Prosthetics has patented a prosthetic socket that aims to provide a more comfortable fit for users by accounting for daily volume changes in the amputee’s residual limb. The Quatro Socket allows users to alter the volume and compression of the device through compression panels controlled by Revofit dials. This allows individuals to adjust the compression on the residual limb for a more comfortable and secure fit. The main challenge the senior design team will face while working on the Quatro Socket is quantifying comfort to back up the anecdotal evidence that this socket design is more comfortable than other designs currently on the market. The senior design team seeks to provide quantitative data that will support the comfort claims made by Quorum Prosthetics. This will be done by creating a Finite Element Analysis (FEA) model of the Quatro Socket and validating this model through benchtop experiments. This analysis will provide quantitative data that will aid in the design of future Quatro Sockets in order to minimize the wear of the socket, respective components, deterioration of collateral tissues and maximize efficiency.
Radar Calibration Using DronesMateo Lovato, Corby Thompson, John (Jack) WilsonProject Video linkPDF linkDepartment of Electrical and Computer EngineeringV. ChandrasekarRadar calibration is important for reading measurements such as the direction, intensity and type (rain, snow, hail etc..) of precipitation accurately. Current methods for calibrating radars include mounting a fixed reflector on a building. Although simple, calibrating in this manner only allows the radar to be calibrated at a fixed elevation and azimuth. In order to provide more extensive calibration, this project is going to use a drone carrying a reflector to calibrate the radar, which will allow the radar to be calibrated in various elevations and azimuths. Having multiple data points for both elevation and azimuth will decrease uncertainty between the measured and actual data, resulting in an improved efficiency. The Radar Calibration Using Drones project will focus on improving the efficiency and cost of calibrating a ground radar.

RBCs interaction with nanostructred surfacesHarvinder Singh VirkNot availablePDF linkDepartment of Mechanical Engineering (MECH 498 Senior Research Practicum)Ketul PopatThere are many implants that come in contact with blood such as stents, artificial heart valves, and vascular grafts. A lot of these medical devices are made of titanium and titanium alloys. Due to undesirable interaction of blood with the implant surface results in inflammation and thrombosis. Thrombosis is one of the main reasons for implant failure, where a blood clot forms on the implant surface, thus obstructing the further flow of the blood. Initially, proteins (fibrinogen and albumin) get adsorbed on the surface which triggers the thrombus formation.

Remote Livestock Monitoring and ManagementHunter McClung, Zach Rafert, Lexy SeeleyProject Video linkPDF linkAgricultural SciencesWade TroxellAgricultural Sciences, Dr. Mark Enns, Dr. Jasmine DillonRanching is a critical job to the world’s food supply system and in Colorado specifically, it is still a job involving vast swaths of land. With these large amounts of land comes the dilemma that a rancher faces on a constant basis, spend time checking cattle by horse/motor vehicle or completing chores around the ranch. Thus, a cattle monitoring system utilizing radio transmitter technology is being developed. A fixed-wing drone will house a receiver node that monitors powered tags on the livestock. The receiver node communicates with a small radio and antenna connected to a computer. This system will allow the rancher to monitor a large area of land much quicker. Once the land has been scanned by the drone, data will be compiled to form a GPS map of the livestock’s location and identity. This project will provide useful information to ranchers that will save them much needed time and energy.

Riff Raff Brewery Solar Hydronic HeatingBrianna Bartlett, Tyler Haman, Annalisa Hund, Shannon Langfield, Arturo Quintero Castillo, Sam StringfieldProject Video linkPDF linkDepartment of Mechanical EngineeringBonnie RobertsRiff Raff Brewery, Jason CoxRiff Raff Solar Hydronic Heating is a project that teamed up with a small brewery in southern Colorado to make their “Earth Powered Beer” slogan a possibility. The team used the foundation made by last year’s senior design students to finish a proof-of-concept prototype and then create a full-scale design with a functional control system. The full-scale design will use the domestic cold water provided by the city and then heat it up through solar panels on the roof. The prototype shows that the solar panels will be able to raise the temperature of the water by at least 40F, which will be used to feed the hot water applications in the brewery. The preheated water will, in turn, reduce the brewery’s dependence on natural gas and lessen their environmental impact

Satisfying our energy sweet tooth: ethanol Fuel from sugarcaneNick Eyerman, Pramit Maskey, Casey Natsch, Jeremy BelinProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanFermenting sugars to produce beverage alcohol dates back to the ancient Egyptians. But using that same process to make liquid fuel first gained momentum as an idea in Brazil in the '20s. Henry Ford also considered ethanol a good fuel for his Model T. In the early '70s, oil prices shot up causing Brazil to invest in sugarcane biofuel manufacturing technology. By the late '70s, Brazil was producing ethanol for fuel at a massive scale and its success is clear today. The US followed a different path to producing fuel grade ethanol, relying on its extensive corn grain supply. In this study, we consider a large-scale process for producing ethanol from sugarcane in the US. We assess the latest technology advances for both the fermentation process and downstream recovery of the fuel and potential byproducts, like heat and power. We address questions such as: 1) what is the cost of sugarcane ethanol in the US vs corn ethanol in the US?, 2) How sustainable (environmentally) is US sugarcane ethanol?
Scaling up COVID-19 Vaccine productionMehdi Rubaii, Lindsey Gilcreest, Sawyer Remillard, Aaron HosackProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanThe breakout of COVID-19 and the subsequent pandemic have caused many to look to engineers and scientists to solve the problem. A race to a vaccine has begun and seemingly, two companies have won. However, these vaccines were passed along under emergency circumstances so they may not be the most economically or environmentally efficient. Producing an environmentally and economically viable vaccine is urgent due to the huge and immediate market demand. Adenovirus and mRNA based vaccines along with different processes to produce them will be investigated to find the vaccine that is most beneficial to everyone. In this project, we design a large scale commercial vaccine production facility that meets the global and societal demands for cost-effectiveness, efficiacy and sustainability.

The purpose is to create homes for long term staff, and it is important to build safe, efficient, and economical homes in a village that will be a welcome respite for employees. Shambhala Mountain Center is at its heart dedicated to the well-being of its residents and guests; the village for long term employees will cement these core principles of care and well-being, building continuity in the most essential element of success, the Shambhala Staff.
Skytask UAV Smart Parachute SystemTrevor Andrews, Garrett Garcia, Ava RaymondProject Video linkPDF linkDepartment of Mechanical EngineeringWade TroxellSkytask, David BeltThe senior design team is working with Skytask Inc to integrate their advanced boundary system for UAV remote inspection and monitoring with a smart parachute system. The parachute system is necessary to receive additional waivers from the FAA to allow for commercial drone flight over people, at night, and beyond the visual line of sight. In the past few years, the FAA has granted more waivers than ever before due to the introduction of the smart parachute system. Our system will deploy a parachute whenever the UAV exceeds the boundary limit, begins to free fall from failure, or if it exceeds its maximum tilt angle. The controls are programmed using a raspberry pi and will be connected to the drone power source. The actuation system is triggered by a stepper motor. The system itself is spring based with projectiles to spread the parachute upon deployment. The enclosure is 3D printed and mounts onto a Tarot 650 V2.1 UAV
Smart GlassesRuben Acosta, Zack SharnProject Video linkPDF linkDepartment of Electrical and Computer EngineeringSudeep PasrichaDavid Robinson, Chris Atib, Denny MoyerThe Smart Glasses Project is about finding a suitable method to improve the quality of life of patients who suffer from macular degeneration. Through sensors and cameras that are equipped on wearable spatial computers, more commonly known as mixed reality goggles, we aim to reframe and allow a patient to see and do more activities without strain. Through glasses such as the Hololens and Magic Leap One, we intend to capture and move video being captured in real-time and move them around a user's field of view, as well as zoom and movement of that image. Accessibility is also important so in order to create a system that can communicate with most mixed reality goggles we aim to design an app to control all features via smartphones or tablets using Bluetooth.

Stem Cell Spinal Cord RepairTaylor Ausec, Katrina Brewer, Courtney Mack, Cailin SullivanProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanStem cell therapy is a quickly growing field in the pharmaceutical industry. Stem cells are undifferentiated cells that have the capability of transforming into different cell types. Human mesenchymal stem cells (hMSCs) can be harvested from normal human adipose tissue, bone marrow, and the umbilical cord matrix of individual donors. Approximately 250,000 people in the United States suffer from life-changing acute spinal cord injuries each year, leading to neurological compromise through an inflammatory response and cell death within the spinal cord. With the use of hMSCs treatments, cell death can be limited in the spinal cord, stimulating growth of new cells, and replacing the injured cells. The aim of this project is to design a biomanufacturing process for hMSCs, from isolation of a a patient's individual cell line through the growth and replication process, separation of the hMSCs from the growth chamber, and packaging of the cells for shipping to the clinical site for use as a therapeutic.

We are also adding 5 new biosensors to improve usability and promote automated control throughout the cell expansion process. We hope these additions will increase the marketability of the Quantum System, and reduce the burden of blood-based cancer on patients in the future.
The new oil: using single-cell plants to feed our refineries with CO2 and sunlightTate Adams, Isabella Brandes, Erica Frank, Jacob Meyerholtz, Shelby Nook, Juan VenegasProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanMany plants—such as soybeans and oil palm—can turn sunlight and CO2 into energy-rich natural oils called lipids or triglycerides. But they pale in comparison to microalgae. These prehistoric, single-cell plants can be manipulated to grow on sunlight and CO2 and convert a large portion of their body weight to oil. And they can tolerate conditions that would be far too severe for conventional agricultural crops. In this project, we design a commercial-scale process based on microalgae’s superior ability to produce oil. It includes a “photobioreactor” designed to efficiently deliver waste CO2 and sunlight, along with other nutrients, to these microscopic plants under conditions that enhance their ability to produce oils. This is followed by a series of steps designed to recover and purify the oil from the reactor's mixture of water and plant cells. We envision replacing fossil petroleum with these natural oils as a feedstock to existing petroleum refineries. While such algal production systems already exist for producing high value oils and nutraceuticals, our challenge is to see if such a process can be built that is kind to the environment and yet economic—in other words, sustainable.

Turning waste CO2 and sunlight into ethylene—a path to green chemicalsAJ Booker, Tierney Johnson, Wit StokesProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanPrimarily produced from fossil fuel derivatives, ethylene is the single most produced organic molecule on the planet. Ethylene is used agriculturally as a plant hormone and industrially to produce plastics. Ethylene’s simple structure, the simplest possible alkene, makes it a perfect precursor for countless reactions. In order to wean society off of fossil fuels, a valid alternative production method for ethylene is essential. Cyanobacteria are a group of bacteria that have the unusual ability to grow on CO2 and sunlight using photosynthesis. They are strange creatures that do not wholly fit in the bacterial world or the plant world. In addition to growing on CO2 and sunlight, some cyanobacteria can be engineered to produce other chemicals, including ethylene. The use of cyanobacteria to produce ethylene has provided promising results and may eventually serve as this alternative method. In this project, we design a commercial scale facility based on photosynthetic production of ethylene from sunlight and CO2 using a genetically engineered strain of cyanobacteria. Our process starts with a photobioreactor that can efficiently deliver sunlight and CO2 (and other nutrients) followed by a series of steps for recovering and purifying ethylene. We evaluate both the economic and environmental aspects of the process, focusing specifically on the benefits of utilizing waste CO2 from other industrial sources.

USDA ORV Delivery TeamMatt Illa, Nathan Jacques, Kurrin Severns, Ryan SmithProject Video linkPDF linkDepartment of Mechanical EngineeringWade TroxellUSDA APHIS, Dr. Amy GilbertThe USDA National Rabies Management Program (NRMP) has reached out to seniors at the college of mechanical engineering in an effort to help improve the effectiveness in which they vaccinate animals for rabies disease. One of the ways in which the program currently vaccinates animals includes dropping Oral Rabies Vaccine (ORV) out of a helicopter on a targeted population along the East Coast. This effort is made to help resolve wildlife damage to a wide variety of resources and reduces threats to human health and safety. Seniors on this project have been tasked with developing an (ORV) bait distribution device that fits in the lap of a crew member in the cockpit/flight deck of a helicopter. The baiting machine needs to be lightweight, have the ability to count baits and geocode locations where baits are distributed, as well as comply with Agency (USDA APHIS Wildlife Services) and FAA safety standards and regulations

Waste not want not—turning Fort Collins' food waste into fuelGarrett Ruf, Finley Martinez, Alexa Jackson, Thamir Sindi, Jacob Tamani, Sydney VillersProject Video linkPDF linkDepartment of Chemical and Biological Engineering John SheehanThe City of Fort Collins has established goals for reducing its discharge of solid waste and reducing its carbon footprint. In this project, we consider the design of a process that addresses both those goals simultaneously. We evaluate a process in which food waste collected by the city would be converted to a liquid fuel using technology called hydrothermal liquefaction (HTL). During HTL, the carbon and hydrogen of the biomass feed is thermo-chemically converted into a “bio-oil” using high temperature and pressure conditions. The bio-oil produced can then be utilized as an alternative, eco-friendly fuel source. One of the advantages of HTL is that, unlike many other biofuels processes, it can efficiently deal with the presence of large amounts of water. Food waste is a perfect target for this technology. Biofuels produced from food waste may have a much smaller carbon footprint. At the same time, food waste processed with HTL avoids disposal of the waste in our local landfill. Our challenge is to design a process that is both cost effective and more sustainable relative to how the City of Fort Collins currently manages its food waste.

Well PlateRyan Barnes, Katie Brown, Najy Faour, Youming Liu, Kailee Mitsuyasu, Aaron Murphy, Ryan Way, Kaitie WoodProject Video linkPDF linkDepartment of Electrical and Computer EngineeringTom ChenThe Smart Well Plate project aims to create a well plate that can detect and quantify cell response to pharmaceuticals in real-time. A typical well plate is a rectangular matrix of wells, which are small chambers in which live cells can be placed for testing. New pharmaceuticals are tested in different concentrations within the separate wells, and, after an incubation period, the cell's response to the drugs is observed. This project focuses on the design and testing of a device that would measure cell response and cellular metabolism in real-time during the incubation period. This is a multifaceted project which involves a team of graduate and undergraduate students of several engineering disciplines. Facets of this project include design and testing of an instrumentation board with power supply and controls, microfluidic electrode design and testing, development of software for a user interface, signal processing of microscopic images, design and testing of mechanical apparatus, and collaboration with several Colorado laboratories involved in cancer research and medical technology. This multidisciplinary approach to the design problem allows for significant collaboration between students studying biomedical, computer, and electrical engineering disciplines.
Wheat Stem Fly SensorCarl Cherne, Meg HansenProject Video linkPDF linkDepartment of Electrical and Computer EngineeringAli PezeshkiDarren CockrellThe Wheat Stem Sawfly Detection team is working in collaboration with the Agricultural Biology Department at Colorado State University to design a device that will detect wheat stem sawfly larvae in wheat stems.   Wheat stem sawflies are insect pests that lay their eggs inside of wheat stems in Colorado.   The eggs hatch and become larvae that feed inside the stems.   In doing so, they destroy wheat crops across the plains of North America.   The larvae feed inside wheat stems before emerging as adults and spreading to adjacent fields.  

There is no known method of detecting sawfly larvae at this time, so our goal this year is to research and test many different hypothetical methods of detecting this pest.   We have been testing three main hypotheses this semester, including testing how light passes through wheat stems, the complex impedances of wheat stems, and attempting to detect vibrations within wheat stems that come from larvae feeding in real time to detect the location of sawfly larvae in stems.

Wireless Signal CharacterizationNick Daly, Huanjia LiuProject Video linkPDF linkDepartment of Electrical and Computer EngineeringBranislav NotarosThe Wireless Signal Characterization project seeks to develop a piece of software capable of modeling the signal propagation of electromagnetic radiation through different environments. This software will be capable of calculating the electric field, power, and phase quantities of a signal. These parameters are useful for the design of digital communication systems especially when complex structures in the environment are considered. An example of this would be the use of this software to find the optimum placement of antennas for maximum power transfer in a communication system. This simulation is accomplished by a technique known as the Shooting and Bouncing Rays technique (SBR). Previous teams were able to implement reflected rays and diffracted rays into the code. This year's focus will primarily be on implementing bistatic radar cross section measurement capabilities to the code base.

Woodward Composite FlowbodyPhilip Allmendinger, Emerson Birch, Ben Dyer, Ryan Fahrenkrug, Jason RichardProject Video linkPDF linkDepartment of Mechanical EngineeringJohn PetroWoodward, Shawn Pollock, Mike MorganThis project is designed to develop a platform for Woodward Inc., a prominent aerospace company, to design future air-valves featured in jet turbine engines that are stronger, more lightweight, and cheaper. The current design of the flowbody (air-valve) is made of Aluminum and features a thin heat shield to withstand emergency conditions within the turbine engine. The aluminum is heavy and the heat shield is fragile, so Woodward wished to improve upon this design. This project features research into high-temperature composite material suppliers to determine how Woodward might manufacture and create these parts, and which suppliers would have the most cost-effective and high-performing materials. Following research into these materials, bench testing samples on various properties to determine which might suit the needs of Woodward was the next step. These tests include a 15-minute 2000 degree flame test, an impact test, and a 100 hour bake test in a kiln. In parallel with testing, a new design of the flowbody was created out of composite materials and run through simulations to prove it would not leak air or burst from the necessary internal pressures as well as maintaining structural integrity at high-temperatures
Woodward Concentrated Winding DC MotorJames Bryce, Will McBryde, Tye Sandoval, Nick Trammell-JamisonProject Video linkPDF linkDepartment of Mechanical EngineeringJohn PetroWoodward, Josh BeenWoodward currently uses an out-sourced DC motor to operate its GS Series Gas Control Valves (HP Aero) and Large Electric Linear Actuators (LELA). The current motor is a distributed winding DC motor, in which the copper windings are arranged in several full-pitch or fractional pitch coils. The goal of this project was to design, analyze, build, and test a concentrated winding DC motor to replace the current distributed winding motor. In contrast to its distributed counterpart, all of the winding turns in a concentrated winding motor are together in series to form one multi-turn coil. Woodward was seeking to replace its current motor with a concentrated alternative to increase performance while simultaneously reducing overall costs associated with the motor. It was also important to maintain the motors inner and outer dimensions for seamless integration. Early research and analysis revealed that a 12 slot/10 pole single-layer configuration would yield the greatest performance for the desired application. As such, the final motor assembly consists of a rotor, laminated stator, 6 wrapped bobbins, and 10 arc magnets, among other components. The concentrated winding prototype was then tested for comparison to the existing distributed winding motor
Woodward Reaction Link Flight Control ActuatorJake Irwin, Andrew Kollar, Eric Robak, Kyle Van AkenProject Video linkPDF linkDepartment of Mechanical EngineeringJohn PetroWoodward, Brian HahnTo maneuver through the air, aircraft actuate "flaps" known as control surfaces. If you’ve ever gotten a window seat on an airplane, you may have seen these flaps along the trailing edge of the wing. These control surfaces are typically actuated by a hydraulic actuator, which utilizes pressurized fluid to extend and retract the piston, therefore rotating the control surface about its hinge. For use in traditional aircraft wings made of aluminum, the hydraulic actuator can be connected to the wing structure at one end and to the control surface at the other. This works because aluminum can handle the large shear forces that the actuator exerts on the wing structure during flight. However, this method of attachment does not work for lightweight composite wing structures, which have been of interest due to their ability to increase the fuel efficiency of aircraft, because composites cannot handle shear forces as well as metals. This issue necessitates a new configuration known as a reaction link actuator, which is designed to direct forces away from the wing structure. We have been working with Woodward Inc. to design, build, and test a prototype reaction link actuator to inform future development of a production model

WSS Jackson Ditch RehabilitationKaty Rodriguez, Sami Fischer, Dillon Gauser, Hannah Gridley, Hunter Ward, Jack ChambersProject Video linkPDF linkDepartment of Civil & Environmental EngineeringThornton, MichalosDonald Frick, Levi StocktonOriginally constructed in 1861, the Jackson Ditch is one of the oldest irrigation ditches in Colorado. It pulls its water from the Poudre River to supply water to 1,700 acres of irrigated farmland. The Jackson can currently hold about 25 cfs while the legal decree is 52 cfs. Many of the issues along the ditch are caused from overgrown trees and elevation changes at the bottom of the ditch. Flowgistics will design a bridge to put over the Little Cache to access a weir, research and perform the appropriate dye test to determine large points of seepage and explore how to minimize that seepage, survey the locations of headgates and elevation change throughout the ditch to create typical cross section plans, grades, excavation and shaping of the ditch to carry 52 cfs, develop a GIS database of existing structures along the ditch, and utilize a LIDAR survey of the ditch to complete a hydraulic model of existing conditions using HEC-RAS.
