Design Of A Near-Constant Force Spring For Orthopedic Implants, Christopher Hartman, Paul Rotarius

Honors Theses

The design and testing of a spring assembly for the attachment of an orthopedic implant is presented. The assembly is intended to supply a constant compressive force of approximately 800 lb. at the bone-implant interface, while exhibiting insensitivity to changes in the displacement of the clamping device. This near-constant force will aid in-growth of bone tissue at the implant surface. This constant compressive force was ultimately not attained due to the packaging dimensions and materials available. However, significant improvement was made upon the current design in use by lowering the spring constant around 800 lb.

The final assembly fits in …

Implementing Rfid Automation Into A Small Scale Aircraft Maintenance System, Daniel D. Bowman

Purdue Polytechnic Directed Projects

The purpose of this study was to explore and identify where technology automation could be used to reduce time and wasted labor in aircraft inventory and maintenance processes. The research used passive RFID AutoID technology due to its capabilities in data logging and relatively hands-off, passive use. The Purdue University’s aircraft maintenance system operates under old time card systems with paper inspection, check outs of tools, and non-routine inspections, contributing to long search times when looking for maintenance problems or lost inventory that may have happened up to and over a year ago. Furthermore, there are general inefficiencies due to …

Process To Produce High Surface Area Nanoparticle Vanadium Phosphorus Oxide Catalyst And Product Derives Thereof, Yun Hin Taufiq-Yap, Ali A. Rownaghi

Chemical and Biochemical Engineering Faculty Research & Creative Works

An improved process to produce high surface area nanoparticle vanadium phosphorus oxide catalysts comprises the steps of reducing vanadium-containing compounds in an alcohol solution selected from the group consisting of isobutanol and benzyl alcohol and any combination derives thereof under reflux for 4 to 6 hours to form a suspended mixture; reacting dopants and phosphorus-containing compounds to the suspended mixture under reflux for 30 minutes to 3 hours to form precursors of the vanadium phosphorus oxide catalysts; drying the formed precursors; and calcining the dried precursors in a flow of gaseous n-butane/air mixture at 400 to 460° C. to form …

Hybrid Micro-/Nanogels For Optical Sensing And Intracellular Imaging, Weitai Wu, Shuiqin Zhou

Publications and Research

Hybrid micro-/nanogels are playing an increasing important part in a diverse range of applications, due to their tunable dimensions, large surface area, stable interior network structure, and a very short response time. We review recent advances and challenges in the developments of hybrid micro-/nanogels toward applications for optical sensing of pH, temperature, glucose, ions, and other species as well as for intracellular imaging. Due to their unique advantages, hybrid micro-/nanogels as optical probes are attracting substantial interests for continuous monitoring of chemical parameters in complex samples such as blood and bioreactor fluids, in chemical research and industry, and in food …

Synthesis And Characterization Of Electrospun Gelatin/Dendrimer Scaffold Encapsulated With A Silver As A Potential Antimicrobial Wound Dressing, Alpana Dongargaonkar

Theses and Dissertations

A novel nanofiber scaffold was fabricated and characterized as a potential antimicrobial wound dressing. Half generation polyamidoamine (PAMAM) dendrimer G3.5 was covalently conjugated to gelatin. Gelatin alone or with gelatin-dendrimer conjugates was electrospun into nanofiber scaffolds. Gelatin is a derivative of natural collagen, and it is biocompatible, non-toxic and inexpensive, making it a desirable component in a wound dressing. Dendrimers are synthetic polymers comprising of a central core, internal branches and reactive surface groups. They provide a structurally controlled architecture for drug release. Silver was incorporated into the scaffold in situ due to its broad spectrum of antimicrobial properties. The …

Reliability Of A Lunar Excavator, Amanda Michelle Huff

Mahurin Honors College Capstone Experience/Thesis Projects

Reliability Engineering is a field of engineering that studies the ability of a system (or component of a system) to function properly under specific conditions for a specific period of time; reliability analysis of such a system can take many forms. This thesis presents a quantified reliability study of a system that the author along with a team of Western Kentucky University Engineering students (designated Team ARTEMIS) designed, built, tested, and entered for competition in the Inaugural National Aeronautics and Space Administration (NASA) Lunabotics Mining Competition in May 2010. A detailed quantitative analysis has been completed using both a Failure …

The Future Of The Gender Wage Gap In The American Workforce, Molly K. Merrick

Mahurin Honors College Capstone Experience/Thesis Projects

This thesis aims to accomplish four goals. First, to establish the extent to which a gender wage gap exists in the American workforce and why it matters. Second, it seeks to explore the various factors that scholars have advanced as potential explanations for this gap with the aim of identifying a more concrete and all-encompassing root cause of the gender wage gap as it exists today. Third, this thesis will individually evaluate a succession of equal pay legislation which has been enacted to date in order to discern the effectiveness of previous attempts to address this root cause, as well …

Virtual R&D Teams: A Potential Growth Of Education-Industry Collaboration, N. Ale Ebrahim, S. Ahmed, S.H. Abdul Rashid, Zahari Taha

Research Publications (2006 to 2010)

In this paper, we present our more than two years research experiences on virtual R&D teams in small and medium-sized enterprises (SMEs) and draws conclusions, giving special attention to the structure of virtual teams required to support education-industry collaboration. We report the relevant results of an online survey study. The online questionnaire was emailed by using a simple random sampling method to 947 manufacturing SMEs. The findings of this study show that SMEs in Malaysia and Iran are willing to use virtual teams for collaboration and the platform for industry-education collaboration is ready and distance between team members or differences …

Automated Tool Design For Complex Free-Form Components, Kevin G. Foster

Theses and Dissertations

In today's competitive manufacturing industries, companies strive to reduce manufacturing development costs and lead times in hopes of reducing costs and capturing more market share from early release of their new or redesigned products. Tooling lead time constraints are some of the more significant challenges facing product development of advanced free-form components. This is especially true for complex designs in which large dies, molds or other large forming tools are required. The lead time for tooling, in general, consists of three main components; material acquisition, tool design and engineering, and tool manufacturing. Lead times for material acquisition and tool manufacture …

Theory And Applications Of Compressive Sensing, Atul Divekar, Okan Ersoy

Department of Electrical and Computer Engineering Technical Reports

This thesis develops algorithms and applications for compressive sensing, a topic in signal processing that allows reconstruction of a signal from a limited number of linear combinations of the signal. New algorithms are described for common remote sensing problems including superresolution and fusion of images. The algorithms show superior results in comparison with conventional methods. We describe a method that uses compressive sensing to reduce the size of image databases used for content based image retrieval. The thesis also describes an improved estimator that enhances the performance of Matching Pursuit type algorithms, several variants of which have been developed for …
