System Architecture Optimization Using Hidden Genes Genetic Algorithms With Applications In Space Trajectory Optimization, Shadi Ahmadi Darani

Dissertations, Master's Theses and Master's Reports

In this dissertation, the concept of hidden genes genetic algorithms is developed. In system architecture optimization problems, the topology of the solution is unknown and hence, the number of design variables is variable. Hidden genes genetic algorithms are genetic algorithm based methods that are developed to handle such problems by hiding some genes in the chromosomes. The genes in the hidden genes genetic algorithms evolve through selection, mutation, and crossover operations. To determine if a gene is hidden or not, binary tags are assigned to them. The value of the tags determine the status of the genes. Different mechanisms are …

Human Powered Vehicle Design Team: Speed Variable Steering Stabilizer, Eric Miller, Matt Kraml

Williams Honors College, Honors Research Projects

The Human Powered Vehicle Competition (HPVC) is held annually by ASME at a few locations. The University of Akron has competed in the ASME-East and ASME-West competitions over the past handful of years against universities from all over the world. Objectives of each team for the competition are three-fold: vehicle design, racing performance, and innovation. Our senior design project involved working on the innovation concept for ASME-East 2018 held at Penn State University during the weekend of 4/13. Speed variable steering was decided upon by the entire HPVC team early in the design process as the innovation choice for this …

Building Entry Flood Barrier, Richard Esker, Shannon Mccall, Andrew Udovich, Brian Foust

Williams Honors College, Honors Research Projects

The purpose of this project is to develop a flood barrier that would resist flood water from entering through the doorways of a building. The goal is to mitigate extensive flooding within a structure. After the disastrous weather events that impacted American citizens late in the year of 2017, the team was inspired to develop a project to help disaster victims. Through extensive preliminary and market research, it was discovered that flooding is a serious issue that affects people all over the world. A product to stop flooding could benefit people in developed countries, but it could also help citizens …

Human Powered Vehicle Frame Design, Analysis, Manufacturing, And Testing, Christopher Reed, Kole W. Williams

Williams Honors College, Honors Research Projects

The University of Akron Human Powered Vehicle Design Team began this academic year with a mission to create a practical, lightweight, safe, and efficient human powered vehicle. The main objectives of ZC18 were inspired by competition in the 2018 Human Powered Vehicle Challenge at ASME E-Fest East. In addition to adhering to the rules of this competition, scoring high on the submitted reports, and competing well in the racing events, the team set a goal to assist in furthering knowledge related to the topic of human powered vehicles.

ZC18 was constructed nearly completely in the University of Akron’s Design Center …

Design Of Shape-Conforming Nosecone For Optimal Fluid Flow From Transonic To Supersonic Range, Anna Tombazzi

Williams Honors College, Honors Research Projects

Modern flight vehicles, such as rockets, missiles, and airplanes, experience a force caused by forebody wave drag during the flight. This drag force is induced when the frontal point of each vehicle breaks the pressure wave during flight. Efforts to reduce this wave drag force to improve flight efficiency include modifying the nosecone profile of the flight vehicles to lower the drag force.

This project revolved around creating a design to make the transformation of nosecone shapes from a ¾ Parabolic profile to a ½ Power Series profile possible, mid-flight. Using a novel nosecone assembly, shape memory alloys (SMAs) and …

Sandia Senior Design Collaboration: Vacuum Sensor Design, James L. Valerio, Eric J. Black, Joseph P. Bednarz, David R. Warther

Williams Honors College, Honors Research Projects

Sandia National Laboratories has requested a fully mechanical device to close a circuit after launch has occurred and the device enters a vacuum. Intended for applications in rockets and missiles, the device must fit in a 36 degree wedge with a 6.8 inch radius that is 6 inches in height and be ready to bolt onto a rocket. The pressure switch must be prevented from actuating until a launch acceleration ranging from 20 to 27g is detected. The pressure switch must close the circuit after a pressure of 10^-1 Torr is reached and before a pressure of 10^{-6 …}
