Investigation Of Toppling Ball Flight In American Football With A Mechanical Field-Goal Kicker, Chase M Pfeifer, Timothy J. Gay, Jeff A. Hawks, Shane Farritor, Judith M. Burnfield
Investigation Of Toppling Ball Flight In American Football With A Mechanical Field-Goal Kicker, Chase M Pfeifer, Timothy J. Gay, Jeff A. Hawks, Shane Farritor, Judith M. Burnfield
Department of Mechanical and Materials Engineering: Faculty Publications
A mechanical field-goal kicking machine was used to investigate toppling ball flight in American football place-kicking, eliminating a number of uncontrollable impact variables present with a human kicker. Ball flight trajectories were recorded using a triangulation-based projectile tracking system to account for the football’s 3-dimensional position during flight as well as initial launch conditions. The football flights were described using kinematic equations relating to projectile motion including stagnant air drag and were compared to measured trajectories as well as projectile motion equations that exclude stagnant air drag. Measured football flight range deviations from the non-drag equations of projectile motion corresponded …

Robotic Mining Digging Core, John Stefan, Ryan Weir
Robotic Mining Digging Core, John Stefan, Ryan Weir
Williams Honors College, Honors Research Projects
The purpose of this design project is to design a digging core for a lunar robot that will collect large amounts of material buried beneath the surface of Mars so one day, astronauts can use those resources. This lunar robot will be competing in the NASA Robotic Mining Competition, where teams from universities around the country display and test their designs. This design must adhere to a newly implemented rule which states that the amount of gravel a robot collects will determine the team score. The layer of gravel is located underneath a layer of Regolith, which simulates the surface …
Meniscus Modeling And Emission Studies Of An Ionic Liquid Ferrofluid Electrospray Source Emitting From A Magneto-Electric Instability, Brandon Jackson
Meniscus Modeling And Emission Studies Of An Ionic Liquid Ferrofluid Electrospray Source Emitting From A Magneto-Electric Instability, Brandon Jackson
Dissertations, Master's Theses and Master's Reports
This dissertation presents three studies on the electrospray of ionic liquid ferrofluid. Ionic liquid ferrofluids are electrically conductive super-paramagnetic fluids which respond strongly in the presence of electric and magnetic fields. When a small reservoir of ionic liquid ferrofluid is positioned within a magnetic field, magnetic stresses will deform the fluid interface into a peak. The addition of a strong electric field will further stress the fluid interface until a threshold stress is reached at which point the surface tension cannot contain the combined stresses and a spray of fluid or ions results at the apex. This process is termed …
System Architecture Optimization Using Hidden Genes Genetic Algorithms With Applications In Space Trajectory Optimization, Shadi Ahmadi Darani
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 …
An Integrated Microstructural-Nanomechanical-Chemical Approach To Examine Material-Specific Characteristics Of Cementitious Interphase Regions, Mahdieh Khedmati, Yong-Rak Kim, Joesph A. Turner, Hani Alanazi, Charles Nguyen
An Integrated Microstructural-Nanomechanical-Chemical Approach To Examine Material-Specific Characteristics Of Cementitious Interphase Regions, Mahdieh Khedmati, Yong-Rak Kim, Joesph A. Turner, Hani Alanazi, Charles Nguyen
Department of Mechanical and Materials Engineering: Faculty Publications
Effective properties and structural performance of cementitious mixtures are substantially governed by the quality of the interphase region because it acts as a bridge transferring forces between aggregates and a binding matrix and is generally susceptible to damage. As alternative binding agents like alkali-activated precursors have obtained substantial attention in recent years, there is a growing need for fundamental knowledge to uncover interphase formation mechanisms. In this paper, two different types of binding materials, i.e., fly ash-based geopolymer and ordinary portland cement, were mixed with limestone aggregate to examine and compare the microstructures and nanomechanical properties of interphase region. To …
