Master of Engineering Capstone Project Teams

  • WorkOutimal (Smart Exercise Machine)

  • The goal of WorkOutimal is to create a stationary exercise bike that is able to passively guide the rider through an efficient workout. An efficient workout, for our purposes, is one in which the combination of force applied by the user and the velocity of pedalling results in a maximum power output. Therefore, the workout is able to burn the most amount of calories per unit time. We will be simulating an ideal control system, while building the hardware to implement a simplified version of the system. Additionally, our team has done market research and created a business plan for bringing this technology to market.

  • Next Generation 3D Printing Materials

  • We are working to create new 3D printer materials that have properties that are determinable by the customer. The printing process should be user-friendly, cost efficient and maintain the integrity of the material, as well as, be easy to produce. Accordingly, our value proposition focuses on customizable 3D printer material, which users are able to choose the properties they want and we will make it for them.

  • Modeling the Design of a Specialized Lubricant for Rotating Machinery

  • We are a bunch of Master of Engineering graduate, working on creating a mathematical model for additive based lubricants. The definition of success or the aim for the project is to build a mechanistic model of the heat generation within a bearing, as a function of the properties of the lubricant and the additives. We will formulate a numerical technique to integrate the model and solve the inverse problem of computing lubricant additives to obtain a given heat generation limit.

  • Modeling the Dynamics of a Swarm

  • A swarm is a system composed of a large amount of simple and identical agents which interact locally among themselves without any central control, allowing complex group behavior and emergent collective intelligence. It involves population based algorithms that can generate fast and robust solutions to complicated optimization problems which traditional approaches cannot solve. The main algorithm used in our project, Particle Swarm Optimization, is a population based, stochastic optimization technique. Our capstone project objective is to create simulation software in MATLAB that reproduces the mathematical models of interaction, or “swarm behavior” using the PSO algorithms.
