Fall 2014
Discarded tires have been an environmental concern in different parts of the world. One mass application to avoid such environmental concern is to use them as embankment fill material in civil engineering projects. In such applications, discarded tires are usually used in a shred form referred as...

Lamberson, Leslie, Pagano, Steven, Hogan, James
The rate-dependent compressive response and resulting fragmentation characteristics of dry ox cortical bone and cyanoacrylate-based cortical bone surrogate material was investigated in two material orientations. Tests were conducted under quasi-static (10−3 s−1) and dynamic (103 s−1) loading in...

Caring for the radial artery post-angiogram: A pilot study on a comparison of three methods of compression
DownloadFall 2010
A coronary angiogram (CATH) is the diagnostic tool used to visualize the coronary arteries of a person’s heart. These arteries can be accessed through the radial artery. Various methods of applying compression to the radial puncture site have been used, but no research has been done to show...

Fall 2014
Ductile and brittle failure behaviors of semi-crystalline polymers such as high density polyethylene (HDPE) were investigated under uni-axial tensile loading at various test conditions. The first part of the thesis examines the influence of aspect ratio of rectangular cross-section on the...

Density, Microstructure, and Strain‑Rate Effects on the Compressive Response of Polyurethane Foams
Download2021-11-09
Bhagavathula, Kapil Bharadwaj, Meredith, Christopher S., Ouellet, Simon, Satapathy, Sikhanda S., Romanyk, Dan L., Hogan, James D.
Background A better understanding of the efect of density, microstructure, and strain rate on the mechanical response of polymeric foam materials is needed to improve their performance. Objective The objective of this paper is to study the combined infuence of density, microstructure, and...

Bhagavathula, Kapil Bharadwaj, Meredith, Christopher S., Ouellet, Simon, Romanyk, Dan L., Hogan, James D.
This study presents a comprehensive experimental study of the evolution of Poisson’s ratio and tangent modulus of polymeric foams during rate dependant uniaxial compression. In this study, polyurethane foams with densities of 195 kg/m3, 244 kg/m3, and 405 kg/m3 obtained from PORON (XRD series)...

Design of FPGA-based Accelerators for Deflate Compression and Decompression using High-Level Synthesis
DownloadFall 2019
As the volumes of data that are transmitted over the internet continue to increase, data compression is becoming increasingly necessary in order to efficiently utilize fixed data storage space and bandwidth. The Deflate compression algorithm is one of the most widely used lossless data...

Spring 2011
With the rise of services like Steam and Xbox Live, multiplayer support has become essential to the success of many commercial video games. Explicit, server-client synchronisation models are bandwidth intensive and error prone to implement, while implicit, peer-to-peer synchronisation models are...

Effect of strain rate on tribological properties of pre-deformed alloys via work function analysis
DownloadFall 2018
In industries such as automobile, aerospace and shipping, components made of magnesium and copper alloy could have the chance to bump against other objects during transportation applications. The damage caused by local deformation at high strain rates when other damage processes are involved,...

Impact Failure of Planetary Materials: Lateral Field Ejecta Measurements using Particle Image Velocimetry
Download2014
Schneider, Markus, Spray, John, Rogers, Robert, Hogan, James, Vincent, Gregory
The dynamic fragmentation of a fine grained granitoid material has been examined. Target thicknesses ranged from 7 to 40 mm and impact energies from 12 to 2,500 J. Combined particle image velocimetry and image enhancement techniques are introduced and have been used to measure the size and...
