Finite Element Analysis Of Embedded Blood Vessel Mechanics, I-En Lin

Theses

Cardiac pump function is closely linked to myocardial oxygen supply during the cardiac cycle. Variations in cardiac output must be met with concurrent shifts in tissue blood flow if changing myocardial oxygen requirements are to be satisfied. Of particular importance is the adequate perfusion of the left ventricular myocardium. Experimental evidence indicates that some ninety percent of left ventricular oxygen demand is generated during systolic contraction of the myocardium. Paradoxically, blood flow measurements in the left coronary artery suggest minimal systolic perfusion. The asynchronous, phasic character of left coronary blood flow and myocardial oxygen demand has prompted much research into …

A Methodology For Designing Spacecraft Onboard Processing Systems, Mohammad Nadeem Ahmad

Theses

A three layer methodology is presented for designing spacecraft onboard computer systems. The system design is perceived as a sequence of three hierarchical layers: the Dedicated Processing Layer, the Application and Support Processing Layer, and the Communications Processing Layer. Each layer implements a distinct set of functions and offers services at different levels of abstraction. As opposed to the ISO/OSI Reference Model, where the prime objective is to implement peripheral interaction between two systems, the layered approach used here is to address the problems in system design itself. The problem is approached in a bottom-up fashion, starting with the description …

A Study Of The Effect Of Oil Added To Toray Driographic Ink On Toning In The Non-Image Areas Of Toray Company's Negative Working Driographic Plates, Joseph El-Yabroudi

Theses

Several studies and investigations have been conducted to test the new Toray plate. The studies revealed that the new plate eliminated many of the problems that used to hinder the progress and development of the driographic plate system. The two major problems with this plate were short run lengths and toning in the non-image areas. This study investigates toning problems in negative working Toray plates. Toning is a term that refers to the non-image areas of the driographic plate that are accepting ink. Previous studies have shown that ink tack and flow do not affect toning in any way. However, …

The Dfs Distributed File System: Design And Implementation, Ananth K. Rao

Theses

This thesis describes the design of an operating system independent distributed file system (DFS) and details the implementation, on a cooperating set of server computers interconnected by means of a communications network. The DFS provides the mechanism by which the file systems of these physically dispersed units are integrated into a single logical unit. Users and application programs thus have the illusion that their files are on a single computer system, even though in reality they may be physically distributed around the network. This location transparency frees users from having to remember details such as the current location of the …

Computing Techniques For The Enumeration Of Cyclic Steiner Systems, Timothy Frenz Carl

Theses

In this thesis a powerful algorithm is developed for finding cyclic Steiner systems. A cyclic Steiner system with parameters S(t,k,v) is a pair ( V,B), where B is a collection of subsets all of size k (called blocks) and V is a t; element set of points, such that each t-subset of V is contained in precisely one block of B. A Steiner system is called cyclic if it has an automorphism carrying the points in a v-cycle. The results obtained so far with this algorithm are given in Table VII of chapter 5. Among the values reported there, are …

Investigation Of Substructuring Principles In The Finite Element Analysis Of An Automotive Space Structure, John E. Martin

Theses

The efficiency of using substructuring in the dynamic analysis of small models is examined by using a university version of ANSYS to perform a series of four case studies on a small, 648 degree of freedom model. The model is based upon the monocoque center section for an automotive space structure and was constructed using STTF 63 plate elements. In each case study, the model was divided into a different substructure configuration. In the configurations used, the model was divided into one, two, three and four substructures, respectively. In each case study, a series of modal analyses was performed for …

Performance Issues In Mid-Sized Relational Database Machines, Larry Sullivan

Theses

Relational database systems have provided end users and application programmers with an improved working environment over older hierarchial and networked database systems. End users now use interactive query languages to inspect and manage their data. And application programs are easier to write and maintain due to the separation of physical data storage information from the application program itself. These and other benefits do not come without a price however. System resource consumption has long been the perceived problem with relational systems. The additional resource demands usually force computing sites to upgrade existing systems or add additional facilities. One method of …

Why (Most) Mergers And Acquisitions Fail: The Causes, The Effects, And How To Lessen The Risk Of Failure, Sheldon R. Chesky

Theses

Most mergers and acquisitions fail to meet the original goals set forth for engaging in the merger. Merger failure is the failure to meet these goals in a reasonable time frame, usually five years. As a result, most mergers and acquisitions fail.

There are several causes of merger failure which are described in detail. The most significant causes are that most corporations merge or acquire for the wrong reasons, and that they fail to do adequate strategic planning before and during the merger process . As a result, up to ninety percent of the mergers and acquisitions consummated during the …

Pay Equity: The Time Is Now, Stephanie Ann Nowack

Theses

The thesis "Pay Equity: The Time Is Now" by Stephanie Ann Nowak explores the persistent issue of wage disparity between men and women in the United States. Highlighting historical and societal factors, Nowak examines how traditional gender roles have contributed to systemic pay inequities, with women consistently earning less than men in comparable positions. This wage gap, exacerbated by societal expectations and occupational segregation, has been perpetuated by entrenched biases that undervalue women’s work, even in fields requiring similar skills to male-dominated roles.

Nowak discusses the impact of landmark legislation, such as the Equal Pay Act of 1964, which aimed …

A Natural Language Interface To Ms-Dos, Donna Indovina Blodgett

Theses

The goal of this thesis was to design and implement a dialog facility to assist novice users of the MS-DOS operating system. A small natural language interface facility called PE-DOS (Plain English DOS) was built, which serves as a front end for a subset of simple MS-DOS commands. PE-DOS accepts English-like terminology and translates it into the appropriate MS-DOS command using a system of recursive transition networks (RTNs). The translated command then is presented to the user along with an English paraphrase of the user's input sentence in an effort to provide confirmation for the intended command in both English …

Intelligent Knowledge Acquisition System, Bong-Soo Youn

Theses

IKAS (Intelligent Knowledge Acquisition System) is an expert system building shell with a machine-assisted concept checker for easy integrated rule-entry. Unlike most expert system shells currently available, IKAS not only performs rule syntax checking, but also maintains semantic integration of the knowledge base by using a Concept Base. The Concept Base is incrementally grown during the cycle of expert system application development and safeguards the whole domain from conceptually conflicting rules by finding possible inconsistencies or duplications of concepts and giving recommendations for possible solutions. Also automatic generalized concept forming using the Inductive Extension Generalization method gives IKAS a capability …

A Simulated Shape Recognition System Using Feature Extraction, Wendy Pan

A simulated shape recognition system using feature extraction was built as an aid for designing robot vision systems. The simulation allows the user to study the effects of image resolution and feature selection on the performance of a vision system that tries to identify unknown 2-D objects. Performance issues that can be studied include identification accuracy and recognition speed as functions of resolution and the size and makeup of the feature set. Two approaches to feature selection were studied as was a nearest neighbor classification algorithm based on Mahalanobis distances. Using a pool of ten objects and twelve features, the …

A Sql Front-End Semantic Data Model, Marc Richard Lodico

Theses

SQLSDM is a "front end" semantic data model to a SQL relational database management system (RDBMS). SQLSDM provides a more semantically complete RDBMS through the implementation of a Domain and Relational Integrity scheme. SQLSDM provides integrity definition functions and a sub-system to interpret SQL commands . Integrity system tables are created through the use of SQLSDM ' s domain definition command and SQL ' s "CREATE TABLE" command. As SQL database update commands are interpreted, SQLSDM uses these integrity tables to enforce domain and referential integrity. SQLSDM operates virtually transparent to the user and provides for greater database consistency and …

Effects Of Irradiation On The Rate Of Water Vapor Transmission Of Food Packaging Materials, Reginald L. A. Vas

Theses

Food can be preserved by irradiation which is the exposure of food to ionising radiation, high energy electron from electron beams or X-rays or gamma rays from Cobalt-60 or Cesium-137 radioisotopes. Irradiation does not leave a residue in the food and it does not make it radioactive. The low level energy levels of Cobalt and Cesium isotopic gamma rays does not induce any radioactivity. Irradiation has the same preservative effect on food as heat treatment, but because irradiation does not appreciably raise the temperature of the food, it is known as 'cold sterilization'.

Irradiation can potentially be used to preserve …
