科罗拉多河无疑是梅萨县及其周边地区最重要的资源之一. The Grand Valley Water Users Association helps regulate and protect this resource by distributing irrigation water in one of the 6 irrigation districts within the area. Currently, water users complete paper cards and return them to dropboxes in order to create a water request. Ditch riders, who relay these requests, collect the cards at these drop boxes. 我们的网络应用程序通过提供一个数字接口来增强这个系统，用水用户可以在他们的移动设备上访问. From this interface they can submit their requests digitally, taking away the need to return to a dropbox location. The application aims to increase the amount and accuracy of these water requests.

There are many different forms of key card locks for keeping buildings secure. One is known as Mifare Classic, a card commonly used in buildings. To read or write a card, a unique authentication key is required. In general, the only way to do this is to use expensive proprietary software. Our goal is to write an app in javascript and C++, that will allow users to read and write to cards that are compatible MiFare Classic. This app will read the cards with an Omnikey 5022 reader that connects to the USB port.

我项目的目标是创建一个名为Orca的程序，它将连接专有和开源的地理空间数据. I am working for and alongside a local geographic information system (GIS) company, Kaart. This will involve creating an extension of an open-source editor for OpenStreetMap called iD to allow entering and storing of proprietary data. The iD editor was chosen because it is an intuitive platform that is hosted on a browser to maximize usability and in effort to reach a wide audience. The project consists of two parts: design of a user interface for inputting GIS data, and the implementation of a database to securely host and manage the data. When complete, my program will enable companies to manage all of their geospatial data on a single platform.

Innovative Textiles, a company located in Grand Junction, Colorado, produces PowerPro, a premium quality braided fishing line. During production, PowerPro fishing line goes through a manual coloration process that is labor-intensive and produces significant color variation in the finished product. A team of senior mechanical engineering students designed and fabricated an automated dye dispensing machine capable of handling five liquid components to reliably produce the company’s Moss Green color. 本机可自动调配四种颜色和丙酮，误差小于0.1 pounds per constituent.

DT Swiss is a bicycle wheel manufacturer with manufacturing facilities in Europe, Asia, and the United States. Grand Junction工厂生产高端自行车车轮，并在美国和南美洲销售. In the wheel building production line, decals with the company’s logo are applied to each wheel rim. After the decals have been applied to the rims, they are then baked at 150°C. Currently, the rack used for this process holds 60 rims. A team of senior mechanical engineering students designed a new rack to hold 80 rims of various sizes to increase the rate of wheel manufacturing.

The United States has over 400 beautiful, culturally important, and inspiring sites within its National Parks. However, vandalism threatens these protected lands, and one of the most destructive types is spray-painted graffiti. Current graffiti remediation methods can leave a site permanently scarred. A proprietary starch solution was developed by a team of Colorado Mesa University (CMU) chemistry students that is 90% effective at removing paint from rock surfaces. The product is biodegradable, environmentally friendly, and effective within a few hours of application. A team of undergraduate senior engineering students has teamed up with the chemistry team to design and develop an Engineered Applicator Device (EAD) that can mix, transport, and apply the starch solution to vandalized areas. The EAD is self-contained, lightweight, and portable so it can be easily carried by park rangers to remote locations. The benefit of this project to the broader engineering technology community is to encourage engineers to apply their knowledge to the well-being and preservation of nature and pursue developing products that encourage sustainability.

FHE is a company in Fruita, Colorado, that specializes in pressure control systems for the oil and gas industry. FracLock是最新的创新产品，通过远程控制将地面设备与井口连接起来. A FracLock unit takes several technicians’ multiple days to assemble. With components in the assembly weighing up to 1800 lb, 有必要使用跨越FHE设施长度和宽度的桥式起重机等设备. Other departments also use the overhead crane for their lifting needs, leading to delays in the FracLock assembly process while waiting for overhead crane availability. FHE要求设计团队在装配过程中消除对桥式起重机的依赖，以缩短装配时间. The team also identified a second opportunity to optimize assembly time. A 2-in-1 piston assembly build/test stand that allows technicians to build and test FracLock piston subassemblies in a method that prevents part damage currently occurring during assembly. These optimizations improve the efficacy of the FracLock assembly process while keeping quality of the product and the safety of the workers a priority.

几千年来，水车一直被用于不同的任务，比如碾碎谷物和为农场提供动力. Like many inventions, waterwheels have been improved over time to increase efficiency. The purpose of this project was to provide a new addition to the water exhibit in Eureka! McConnell Science Museum. 两个设计选择为这个新的展览，以证明效率是一个下冲轮和一个上冲轮. 这些车轮的功率输出和相对效率由每个车轮上的LED灯条表示. Water flow to each wheel will be easily manipulated by museum visitors using current components of the exhibit to increase or decrease the flow of water to each wheel. The LED light strips will indicate the power produced by each wheel. It is important to the designers that the exhibit is educational and easy to understand for all ages.

The purpose of this project was to design and manufacture a re-sizable 3-D printer enclosure. The design targets 3-D printers that employ the Fused Deposition Modeling (FDM) technique, 哪些会产生大量有害的气溶胶，导致室内空气质量恶化. There are enclosures on the market which capture harmful emissions, but the majority of enclosures only accommodate specific printer models. The implementation of nested aluminum tubing allows the enclosure designed by our team to resize into a minimum and maximum volume of 8 ft 3 and 27 ft 3 , respectively. 当外壳尺寸改变时，亚克力板附着在铝制框架上并相互滑动. The enclosure includes a filtration system that houses an activated carbon and HEPA filter that captures 90% of the number concentration of aerosol emissions within the enclosure. The enclosure accommodates 95% of common tabletop 3-D printers.

Ute Water Conservancy District is a water utility company that delivers water across the Grand Valley. With a mission statement of providing only the highest quality water to their clients, this project was created to uphold that promise. Currently, the company faces a problem with its inclined plate settler assemblies accruing sediment and algae. These assemblies assist in the sedimentation phase at the treatment plant. The company must partially shut down a settling pond to clean each assembly, which is both labor intensive and costly. 这个项目的目的是设计和制造一个自动装置，在不关闭沉淀池的情况下去除这种堆积. To avoid the partial shutdown the project meets the following criteria: autonomous, lightweight, and waterproof. 一组高级机械工程专业的学生设计并制造了一个机器人装置来清除平板沉降装置上的堆积物. The Semi-Aquatic Continuously Roving Utility Bot (S.C.R.U.B.)利用刷子和UVC LED灯的组合来清除每个板组件上的沉积物和藻类.

Capco is a company in Grand Junction, Colorado that manufactures the M320 grenade launcher for the U.S. Armed Forces. When this firearm is fired, the recoil force is significant enough that an operator is limited to 25 rounds a day. To increase the number of rounds a soldier can fire in a day, Capco公司正在设计一种新的枪托原型，这种枪托设计可以降低操作人员在发射时所经历的最大后坐力. The purpose of this project is to design and fabricate a test stand to measure recoil force and displacement as a function of time when the launcher is fired with prototype buttstocks and the currently issued buttstock. The damping coefficients of each buttstock will be calculated from the collected data to determine which buttstock transmits the smallest force when the launcher is fired. The dynamometer will be used by Capco to make design improvements for future buttstock prototypes.

The City of Grand Junction plans to extend the recently constructed Monument Road Bike Trail to connect the Lunch Loop trail-head with an existing bike trail on South Camp road. When this section is complete the trail will form a loop that provides miles of biking trails. 该市希望鼓励骑行者走上这条道路，因此设计的社会影响是一个重要的考虑因素. This design project presents the design of the proposed trail alignment, as well as an engineering cost estimate. 另一项分析考虑了不同的路线和交叉路口，以确保跟踪用户的安全, cost of construction, maintenance concerns, ease of use, flood hazards, and property owners. These criteria were used to select an alignment, as well as water conveyance structures. The project deliverable includes preliminary design drawings and calculations. The final deliverable to the City will include details of stream crossings, a cost estimate, grading plans, alignment plan and profiles, and cross sections of trail.

The purpose of this project is to redesign a culvert on Highway 340 near Fruita, Colorado. Culverts are designed to decrease future flooding problems near transportation infrastructure while still allowing the passage of water and animals. This allows for a natural flow path to be maintained within a controlled environment. This project is in partnership with the Colorado Department of Transportation (CDOT) and aims to improve an existing culvert for maintenance, transportation safety, sustainable infrastructure, and animal passage. To accomplish this, hydrologic flow analyses, alternative design options, and a cost analysis for the chosen design have been conducted. Alternative designs included complete replacement, slip-lining, direct repair, and cured-in-place designs. This project includes permitting, regulatory research, environmental, sustainability, right-of-way, utility, and transportation factors that will contribute to the project construction timeline and cost. A 30% project design will be completed for CDOT by May 2020. This will include hydrologic analyses, transportation research, utility investigations, cost estimate, and chosen alternative design.

Track 4D - Oral Presentations

Currently, biosensor research identifying stress through physiological responses is completed with state-of-the-art sensors comprised of high-quality and high-price materials. These projects are generating substantial results and noteworthy findings. However, 目前还缺乏用于普通大众的这些高级应力检测工具的低成本版本的复制和生产. 该项目旨在通过开发由三种经济材料组成的概念验证设备来探索这一差距, accessible sensors: a galvanic skin response (GSR) sensor for measuring electric resistance, an electromyography (EMG) sensor for measuring muscle stimulation, and a photoplethysmography (PPG) pulse sensor. Using this prototype device, pilot data of physical responses was collected and analyzed during exercise, which is a fundamental form of stress on the body.

Both developers and students alike could benefit from learning web application security. However, 对于一般人来说，获得一个完整的web应用程序来测试漏洞是很困难的. Web application security tools exist, but the most popular ones (WebGoat, NodeGoat, etc.) are based in more enterprise-friendly languages like NodeJS and Java. This makes writing lessons about additional vulnerabilities quite the challenge. Python is one of the most commonly used languages among security professionals and, to the best of our knowledge, no Python-based web app education frameworks have been created yet. 我们打算用PyGoat来填补这一空白——PyGoat是一个关注Python安全漏洞的web应用程序漏洞集合. 我们还希望通过简单的配置文件编写更多关于新的和即将到来的漏洞的课程. The end result will be an easily accessible, deliberately insecure web application that anyone can learn from.
