The Capstone Design Expo is an opportunity for our students to showcase the results from their capstone design course. Student teams work to create a specific design solution for a "customer’s" real and unique need. Design and design education are, by their nature, experiential and collaborative, and our design team sponsors are our key collaborators. As a result of this collaboration, students bring energy and new ideas to meet the design need.
The design projects enable our students to put into practice what they have learned to prepare them for the workforce.

To develop an economical process to remove hydrogen sulfide (H2S) from 21.3 billion kilograms per year of saltwater brine, reducing the concentration from 450 ppm with less than 10 ppm, with a downstream process to convert the H2S into a saleable product. The H2S removal from the brine feed will be modeled with a series of conventional chemical engineering unit operations, and the conversion of H2S to elemental sulfur will be modeled with catalytic reactors. The project will include a cost estimate (+/- 25%) of the designed system, a permitting and regulatory compliance assessment, and a review of the safety and hazards associated with the system.

To develop a preliminary design for a compact liquid fuel processing system that can produce high-purity hydrogen for use in a PEM fuel cell used to power an automobile. A CHEMCAD simulation will be created in the design of the fuel processing system in addition to research on oil reforming methods, catalysts, and liquid fuel sources. Analysis will also be done to determine the net positive energy output and to determine a reasonable cost for the proposed design. Additional factors to consider when selecting a fuel include environmental impact and availability of materials.

To study the feasibility of integrating machine learning techniques to enhance the Non-Playable Characters (NPCs) behavior and make the gameplay evolutive and more “fun”. In current video game development, the behavior of NPCs is oversimplified, insufficient, and rigid. Inevitably, this leads to predictable and similar actions being taken to overcome the game’s challenges. Hence, the player can learn how to beat sections of the game repeatedly, causing a short lifespan for a game and a fast drop of its entertaining characteristics.
