Conscious Visions, Masako Nitz

Theses

My goal in creating this body of work is to investigate narrative painting using images which are personally relevant. I have labeled my paintings as representations of personal allegories derived from memories and dreams, and in doing so I am referring to the transference of memory, and its inherently subjective and ambiguous visual images, into a concrete visual form. I also attach symbolic importance to the memories I have chosen to paint, not because the events they describe are hallmarks of my life, but rather for their random nature. These images all describe moments when I have consciously thought "I …

Low Frequency Characterization Of A Loop Antenna, Irene Koukhta

Theses

The conventional solution of an integral equation for the loop antenna in free space can be expressed analytically using Fourier Series. However, the solutions based on delta gap feed model yield divergent input susceptance.

To overcome such diverging results, alternative solution using equivalent magnetic frill current feed models were implemented. Although low frequency models for delta gap feeds were suggested, no generalized low frequency expansions for the input admittance have been reported previously. In this work, such generalized low frequency expansion are developed for both delta-gap and magnetic frill feeds of loop antennas. Validity of such expansion have been investigated …

Object Oriented Partitioning For A Medical Vocabulary Based On Semantic Network, Mansnimar Singh

Theses

Computers have become ubiquitous and indispensable part of everyday life both for personal use and in the workplace. Medicine is one of the few domains that has not fully adopted computerization. One impediment to this emanates from a communication gap between the computer science professional and the medical professional. Besides, medical terminology is full of synonyms and medical professionals use them according to their personal preferences. This lack of common terminology has prevented sharing of knowledge and automating data processing, resulting in the healthcare information explosion.

Semantic network models have been developed to represent medical concepts and to provide a …

Parameters' Analysis Of 3d Random Stacking Palletization, Najeeb Syed

Theses

Palletization is a very important element of production, distribution and warehousing activities. The 3D random stacking palletization method is based on volume utilization instead of surface area optimization. Random stacking provides interlocking among the boxes and hence it improves the stability of the pallet load. Volumetric Pallet Utilization is normally the prime concern of any palletization process, with Work in Process and Palletization time being also important. This research uses data generated from a previous heuristic to establish mathematical relationships between the three mentioned performance indices and also three additional indirect variables, namely: Total Number of Sub Volumes, Partitioned Remaining …

Analysis Of The Thermoelastic Response Of A Semi-Space To A Short Laser Pulse, Gary Renz

Theses

A study of the thermoelastic response of a semi-space medium to a short laser pulse generated heat is presented. This study uses the generalized thermoelasticity theory proposed by Green and Lindsay. This theory generalizes the classical theory of thermoelasticity by developing hyperbolic heat conduction equations and temperature-rate dependent constitutive equations. By so doing, an inherent paradox and physically unrealistic result in the classical theory of thermoelasticity that proposes infinite speed of thermal responses through a medium is corrected. Its validity is justified by the satisfaction of Fourier's law by which classical thermoelasticity is based. The Green-Lindsay theory adopts two thermal …
