Presentation: Thursday, May 1 from 5:30-6:15 pm in EMS 250

Project Findings:

Our senior design project focused on creating a safe and easy-to-use device that helps doctors give eye injections more consistently.

We designed a handheld tool that uses a spring to automatically pull the needle back after the injection, reducing the chance of injury or error. The device has two buttons: one inserts the needle, and the other delivers the medicine. A viewing window lets the user see that the medicine has been given, and a side latch keeps everything in place until the injection is complete.

Our design aims to make eye injections safer, faster, and more comfortable for both doctors and patients.

Advisor: Ayesha Nipu, Computer Science

Findings:

Event Radar is a web application designed for organizations and individuals that want to create, view, and manage events. A common challenge that individuals experience is searching for events but information of these events are scattered across various sources. Therefore, it is difficult to create a plan conveniently. Event Radar addresses this issue by offering features that are beneficial to organizations, event planners, and event attendees.

During the development of Event Radar, there was various challenges related to event planning and convenience. Therefore, the application was designed with features that address those inconveniences and other needs. Event Radar provides features for attendees such as viewing available events on a map, adding events to a plan, checking a 3-day weather forecast, and discovering other non-event attractions to visit. Organizers and planners are referred to as event managers. They can easily create and promote their events through Event Radar. Event managers are screened to ensure that quality events are listed. By having an application with these features, it makes it convenient to participate and plan events. Event Radar is an application that involves event discovery, event planning, and management for the users and organizers.

Our project is a web-based MIPS Emulator designed to help students learn assembly language more intuitively. Existing tools are outdated, require installation, and lack modern educational features. We created a browser-enabled emulator that allows students to write, assemble, and run MIPS code without any installation.

Our solution includes key features such as syntax highlighting in the editor, console output, register and memory displays, step-by-step execution, and breakpoints. We also added a built-in MIPS instruction manual pop-out, making it easy for students to reference as they write code. This helps make MIPS assembly more approachable for beginners.

We utilized WebAssembly for the core simulation logic and connected it to a modern front-end interface, without modifying the backend provided by Professor Thomas.

As a result, our project offers a student first, easy-to-use platform that simplifies learning and improves upon existing MIPS tools.

Advisor: Ayesha Nipu, Computer Science

This project our team tackled a complicated relationship between hardware and software. Our design was the same concept from the planning days, with our sensors being designed for hyper-local use and the software being able to keep up and display content seamlessly. Our project uses sensors connected to a mini-computer to display readings on things like air quality index and particulate matter in an indoor setting. This data is then transferred to our website where it is gathered into graphs and easy-to-read data points.

The intention is that the data can be monitored at all times, therefore all of our graphs are set to update every 5 seconds. Another draw to our project is the integrated chat-bot feature which allows the user to request certain information from the database on the fly. The system in place is designed to listen for certain words and be able to respond to them accordingly. This has also been modified to include an large language model of Deepseek, so users can place their own key into the site and have access to a fully cloud-based ChatGPT equivalent. Users can then either monitor there fast-updating data or export it to share however they please.

Overall our group was able to showcase all of our skills and understanding of the topic of computer science. We were able to display the knowledge we have on front-end, back-end, and hardware development in a neat and orderly package.

Project Presentation: Tuesday, April 29 from 3:15-4:00 pm in EMS E250

Project Findings:

GE Healthcare presented the team with a problem related to crevice corrosion, noting a lack of specific data to inform the design decisions of their engineering teams. The UWM team had taken a fresh engineering research approach to tackle the problem. The team was ultimately successful in their endeavor and collected a useful amount of data that then was analyzed and extrapolated.

The team found that the rate of corrosion in the system confirmed GE’s initial concerns when they brought the project to the team. Fortunately, the team’s data had predicted an unacceptable amount of corrosion that would compromise the quality and performance of the CT Detector Thermal Cooling System. In response, the team proposed two design recommendations using different design approaches. Which are redesigning the cooling channel and by implanting cathodic protection.

This project not only addressed a real-world engineering problem but also gave the students valuable insight into the daily responsibilities and problem-solving processes of professional engineers in industry.

Project Advisor: Mohamed Yahiaoui, Senior Lecturer Mechanical Engineering

Project Presentation: Thursday, May 1 from 3:15-4:00 pm in EMS E250

Project Findings:

The project successfully resulted in the design and implementation of an in-house environmental chamber capable of reaching and maintaining the target temperature range of –40C to 120C. The system was fully integrated into HellermannTyton’s existing test enclosure and shaker table apparatus. The final assembly was installed at HellermannTyton’s facility, where it is currently operational and ready for component pre-screening.

The chamber utilizes liquid nitrogen for cooling and a heat gun for the heating. A solenoid valve is utilized to provide on-off control of the nitrogen flow. The thermal system is being controlled via dual thermostat controllers enabling basic set point temperature control. The liquid nitrogen delivery system was designed for safe and reliable operation, cryogenic fittings with fully sealed threads were utilized to withstand thermal effects and prevent leakage. The nitrogen line was routed and mounted in a way that maximizes cooling coverage without sacrificing any safety by reducing the risk of human or vibrational interference.

Prototype testing confirmed that the chamber could withstand vibration produced from the shaker table, reach and maintain both ends of the temperature range of –40C to 120C, and safely deliver flow of nitrogen to the chamber as required. All modifications and additions to the chamber were completed under budget coming in at a total of $707 staying well within the project’s budget of $1000.
