Energy Efficient Hybrid Computing Systems Using Spin Devices, Mrigank Sharad Jul 2014

Energy Efficient Hybrid Computing Systems Using Spin Devices, Mrigank Sharad

Open Access Dissertations

Emerging spin-devices like magnetic tunnel junctions (MTJ's), spin-valves and domain wall magnets (DWM) have opened new avenues for spin-based logic design. This work explored potential computing applications which can exploit such devices for higher energy-efficiency and performance. The proposed applications involve hybrid design schemes, where charge-based devices supplement the spin-devices, to gain large benefits at the system level. As an example, lateral spin valves (LSV) involve switching of nanomagnets using spin-polarized current injection through a metallic channel such as Cu. Such spin-torque based devices possess several interesting properties that can be exploited for ultra-low power computation. Analog characteristic of ...


How Engineering Innovators Characterize Engineering Innovativeness: A Qualitative Study, Daniel Michael Ferguson Oct 2013

How Engineering Innovators Characterize Engineering Innovativeness: A Qualitative Study, Daniel Michael Ferguson

Open Access Dissertations

The use of science and engineering skills to address the problems of modern society is regarded as an economic strategy in developed countries across the world. However, business and political leaders in the United States feel that we, as a society, do not understand that new global competition can match and even outpace us on innovation. Many of the studies on innovators are not specific to engineers. This study filled a gap in the understanding of what characteristics constitute innovative behavior in engineers.

The purpose of this study was to explore engineers' views of innovation and innovators who create and ...


Engineering Modeling, Analysis And Optimal Design Of Custom Foot Orthotic, Lieselle Enid Trinidad Sep 2011

Engineering Modeling, Analysis And Optimal Design Of Custom Foot Orthotic, Lieselle Enid Trinidad

Open Access Dissertations

This research details a procedure for the systematic design of custom foot orthotics based on simulation models and their validation through experimental and clinical studies. These models may ultimately be able to replace the use of empirical tables for designing custom foot orthotics and enable optimal design thicknesses based on the body weight and activities of end-users. Similarly, they may facilitate effortless simulation of various orthotic and loading conditions, changes in material properties, and foot deformities by simply altering model parameters. Finally, these models and the corresponding results may also form the basis for subsequent design of a new generation ...
