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.

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.
