Development Of Physics Based Machine Learning Algorithms, Rob Jennings Jan 2019

Development Of Physics Based Machine Learning Algorithms, Rob Jennings

Master’s Theses

In this study, a baseball pitch was examined to try to understand its behavior, and make a predictive model of it. A baseball pitch was tested experimentally with a wind tunnel and modeled computationally with COMSOL CFD software. Five input variables (spin rate, sting angle, seam orientation: Y axis, seam orientation: Z axis, and air velocity) were controlled, with force in three axes recorded as outputs. The experimental and computational results were examined and seen to be interdependent for all input variables. Experimental and computational data were both insufficient for predicting system behavior. Experimental data collection would have required an ...


Recumbent Bicycle Balancing Aid, James Hager Jan 2019

Recumbent Bicycle Balancing Aid, James Hager

Williams Honors College, Honors Research Projects

For our senior design project, our team will be consulting to create a balancing aid system intended for the recumbent bicycle shown below in Figure 1. The owner of the bicycle is Robert Henderson, a former United States Navy sailor from Northeast Ohio who picked up biking and skiing while he was stationed in Maine in the late 80’s. While there, he took to the mountains on the rugged terrain and brought this passion of biking back home to share with his wife, Johanna once he completed his service to his country. Biking became an integral part of the ...


Stair Climbing Hand Truck, James Mcpherson Jan 2019

Stair Climbing Hand Truck, James Mcpherson

All Undergraduate Projects

Abstract

Getting a heavy object up a flight of stairs usually requires a team of two or more people. Even with a team of people, the task is often still difficult, dangerous, and possibly insurmountable by one person. This problem is especially prevalent in for those who are moving into apartment complexes. Most apartment complexes have many buildings with two or more floors of living quarters, and elevators are often missing. This project sought to offer a solution to this problem. The solution in question; a motorized hand-truck with 2, trigonal planar pinwheels in place of the stock wheels. The ...


Autojack - Hydraulic Powertrain System, Tyce Vu Jan 2019

Autojack - Hydraulic Powertrain System, Tyce Vu

All Undergraduate Projects

A primary problem for mechanics and automotive enthusiasts is the risk associated with lifting and securing a vehicle with conventional jack stands. Often times, improper jack-stand installation results in the vehicle collapsing unexpectedly, causing injury and/or death. This problem can be minimized through the application of a newly re-designed vehicle lifting system. The conventional method for lifting cars is time consuming and can be unsafe in many circumstances. A better, safer, and more efficient lift design was needed; the AutoJack. The approach of the AutoJack design was entirely focused on the safety of lifting a vehicle. Safety was improved ...
