WildFire Technologies–Geographic Data Analysis, Multi-UAV ML Path Planning, and Computer Vision Efficiency Enhancement

Our team project is basically divided into three parts. In the first part, the team will dive into wildfire geographic data collection and analysis. Annually burned area size and locations of each state will be calculated and analyzed by pixel computation. We will also visualize the data and provide solid supports for following multi-UAV path planning. In the second part, after selecting one or several specific high-risk locations as examples, we employ machine learning/GE Algorithm to multi-UAV path planning model, aiming to minimize various kinds of cost, like energy and human resources, by modifying parameters including domain, location weight, UAVs’ mass, speed, and initial distribution. In the third part, we focus on flash-based ToF and Lidar-based body scanning process by enhancing its performance on the speed and accuracy of simulation, enlarging scanning scope, and applying to real occasions including wildfire emergency.

Simulation and Optimization of Fused Deposition Modeling(FDM) Process

The market of Additive Manufacturing process has grown dramatically from 5 billions to 7 billions by 40% in 2018. However, this process is hard to simulate because of its transient(time-depending) model. In order to model this process, I had utilized Star-CCM+ and its API in Java to generate a simulation model. Further, optimizations and several parameter studies regarding to printing environment are conducted with the simulation model.

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.

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.
