Extracting Parallelism At Compile-Time Through Dependence Analysis & Cloning Techniques In An Object-Based Paradigm, Binoy Ravindran

Theses

The construct of Abstract Data Type (ADT) modules and Abstract Data Object (ADO) modules supported by most object-based languages are a great source for developing reusable code. To improve the run time performance of such object-based programs, we consider the asynchronous remote procedure call (ARPC) model of parallel execution, in which concurrency is achieved by having the caller and the callee (which are module instances) running on different processors. Frequently, an ADT module is needed simultaneously by other modules, thus causing contention. To resolve this, we clone the module instance in demand and distribute the copies across different processors, so …

Modeling, Simulation And Hemodynamic Response Analysis Of Arteriovenous Malformation Occlusion, Huijuan Mao

Theses

The cerebral Arteriovenous Malformation system (AVM) or fistula, is a network with large caliber vessels that yields an alternate pathway for blood flow between arteries and veins. Neurosurgical and interventional radiological techniques are the common way to treat AVM patients so that the normal capillary blood flow would be restored. Several patients who underwent this procedure had different degrees of brain swelling and subsequent hemorrhage. To understand this, Blesser et al. developed a simplified model to simulate the effect of AVM occlusion on cerebrovascular pressure and flow. Their model does not include the cerebrovascular regulatory mechanism which is an important …

A Novel Beam-Assisted Thickness Measurement Technique For Nanostructures, Luis Manual Casas

Theses

A novel method for measuring thickness of thin films has been developed. This method is straightforward, quickly accomplished, and offers resolution of device layers approaching that given by transmission electron microscopy. Ion beam bombardment of a multi-layer structure forms a crater in which the crater sidewalls are beveled at a very shallow angle, revealing various layers within the sample at a high degree of magnification. Beveled film thicknesses are measured by scanning Auger electron spectroscopy. Depth profilometry is used to measure the shallow beveling angle. Through knowledge of the beveled layer thickness and the bevel angle, actual film thicknesses are …

Optimization techniques and modifications have been developed to provide long life, trouble-free high-speed indexing and intermittent motion while minimizing the undesirable inherent dynamic characteristics of this class of mechanisms.

A general information base of the motion characteristics and types of geneva mechanisms available has been established. Development of the full spectrum of the required equations, generation of the normalized values of critical design parameters along with …

Multi-Disk Subsystem Organizations For Very Large Databases, Zhiyi Huang

Theses

This thesis investigates efficient mappings of very large databases with non-uniform access to its data. to a. multi-disk subsystem.

Two algorithms are developed to distribute the database across multiple disks, possibly with replication, in order to minimize latency and maximize throughput. These algorithms are compared with respect to the amount of replication overhead incurred to achieve desired throughput.

A simulator is developed to simulate these two mapping algorithms and investigate the efficiency of these two mappings.

Prevention Of Occupational Exposure Of Tuberculosis To Health Care Workers, Thomas C. Carle

Theses

The resurgence of tuberculosis in the United States within the past decade has prompted the health care community to develop tuberculosis elimination policies. However, recent outbreaks of tuberculosis have proved to be resistant to multiple antibiotics. Tuberculosis infections among health care workers is also rising. This increase in occupational exposures has prompted the examination of current exposure control measures.

The occupational exposure to tuberculosis is prevented by the use of administrative policies, engineering controls and personal protective equipment. Each control measure has inherent strengths and weaknesses and when implemented through an exposure control plan the risk of occupational exposure can …

The Application Of Stereolithography To The Creation Of Molecular Models Of Amiloride And Its Analogues, Thomas John Busanic

Theses

Stereolithography, a process by which a computer-guided Ultraviolet (UV) laser is applied onto a liquid monomer resin to form a solid polymer, was used to create solid models of amiloride and two of its analogues. The Cartesian coordinates used as input for the orientation of each atom in a molecule were calculated using ab initio molecular orbital theory. Since the structures of the molecules are calculated in this fashion, they represent a more accurate representation of the molecules than that provided by standard molecular modeling kits.

The original purpose of this work was to assist a blind chemist in appreciating …

Measurement Of Oxygenated Volatile Organic Compounds Using The Thermionic Ionization Detector, Wanfang Li

Theses

A thermionic ionization detector (TID) consists of a catalytically active, low work function heated source. It responds to molecules with high electron affinity which can extract electrons from the surface of the source to form negative ions. TID has been used as selective detectors for nitrogen and phosphorous compounds (NPD). In this research, a TID has been used for selective detection of oxygenated volatile organic compounds (VOCs). The response of the TID to different oxygenated and chlorinated VOCs compounds was studied. To evaluated its performance, the analysis was done using a FID in parallel with the TID. For most of …

A Tutorial In Frequency Modulation Screening Technology For Lithography, Michael Mell

Theses

An impressive diversity of opinions concerning many important aspects of the Frequency Modulation process are heard from users and vendors. It has not been difficult to catch a single vendor contradicting themselves within their own publications. Many of the claims vendors make are not supported by users' experiences. Other users, on the other hand, have found many of the vendors' brightest claims to be realistic. The information sought for this project was aimed to answer the question "What can I expect if I implement Frequency Modulation screening technology in my shop today?" In order to answer that question effectively, a …

Sfumato And Conjunction, Scott Joseph Dohring

Theses

For the studio section of my MFA in painting thesis, I have produced a series of paintings on canvas concerned with non-objective impasto/textured color fields, some include representation in line, abstract overlays/underlays, while some involve division of the canvas into abutting characteristic approaches. The mediums used include water based & oil based paints, textural compounds (gel medium, joint compound, mastic, talc), pencil, and occasionally found objects. In this paper, I shall analyze and discuss impressions, concepts, and meditations relevant to my thesis work in particular and to the issue of reconciliation between formalist and post-modern approaches to theory/criticism in general …

A Gender Specific Interactive Project To Promote Bilingual Literacy In American Sign Language And Written English, Catherine Stotts

Theses

What do young adults (age 12-18) think entertainment consists of? Is it movies, television, computer games, video tapes, multi-media products? What about books, are books considered entertainment? Because interactive multi-media can incorporate text, sound, music, animation, Quicktime movies and allows user interaction, books have become a neglected part of the entertainment market. Even though multi-media can be highly interactive, reading books is highly interactive too. The readers must use their imagination to construct the many images, sounds, and moods of the book. There is the concern that people really don't know how to read. A vast majority of these multi-media …

An Investigation Of Amplitude & Frequency Modulated Screening On Dot Gain And Variability, Kelly Laughlin

Theses

This study examines the effect of screening on dot gain and variability. Essentially two hypotheses are examined: first that as screen ruling is increased, the level of dot gain is increased; and second that as screen ruling is increased the level of variability is increased. These predictions are also applied to stochastic or frequency modulated screens which are presumed to behave as very screens due to their fine dot structure. A mathematical model referred to as the border zone is proposed to describe the nature of the gain and the variability for each of the screening systems. The hypotheses were …

On Issues Of Equalization With The Decorrelation Algorithm : Fast Converging Structures And Finite-Precision, Andrew James Bateman

Theses

To increase the rate of convergence of the blind, adaptive, decision feedback equalizer based on the decorrelation criterion, structures have been proposed which dramatically increase the complexity of the equalizer. The complexity of an algorithm has a direct bearing on the cost of implementing the algorithm in either hardware or software. In this thesis, more computationally efficient structures, based on the fast transversal filter and lattice algorithms, are proposed for the decorrelation algorithm which maintain the high rate of convergence of the more complex algorithms. Furthermore, the performance of the decorrelation algorithm in a finite-precision environment will be studied and …

Art In Motion, Gwendolyn Johnson

Theses

The world of electronic publishing changes quickly, and CD-ROM is the latest technology. Many electronic publishers are getting involved in what is called CD-ROM publishing (also called Optical publishing). CD-ROM means Compact-Disc Read Only Memory. CD-ROM publishing changes the way information is presented, searched, retrieved, and distributed. Electronic publishing takes on a whole new identity with CD-ROMs. The computer screen now replaces hard copy as the viewing medium. This is why CD-ROMs are called the "new CD-ROMs allow the user to deal with dynamic and "moving" images in lieu of static ones. The technology promotes the fact that CD-ROM applications …

The Development Of Clues Dealing With The Contextual Hints Of The Make-Up Of A Document That Will Aid In The Automatic Application To A Specific Style Sheet, Karen L. Johnson

Theses

Software programs have brought about significant changes in computer technology. There once was a time when most software programs were only capable of handling very few typo graphic styles and design applications. Graphic importation wasn't even heard of. But today, there are numerous software programs that are capable of handling unlimited design styles, such color, text wrapping, rotation, and even graphic importation and exportation. Ami Pro is one of those software programs. Ami Pro is a powerful and "user-friendly" software program that was developed by the Lotus Development Corporation for MS DOS Windows. It is primarily used to serve the …

The Contributions To The History Of Graphic Design By Dr. Robert L. Leslie And The Composing Room, Inc. 1927 - 1942, Erin K. Malone

Theses

The topic of Dr. Leslie's role in the history of graphic design was mentioned by Professor R. Roger Remington in the Spring of my first year at RIT. I had read brief mentions about Dr. Leslie in both Nine Pioneers of Graphic Design and Graphic Design In America and felt this was an interesting topic that deserved more atten tion. The ultimate decision to research and write about Dr. Robert L. Leslie came about due to my interest in both design history and the field of printing. I had been introduced to the history of printing in David Pankow's class, …

Kinematic Analysis And Synthesis Of Four-Bar Mechanisms For Straight Line Coupler Curves, Arun K. Natesan

Theses

Mechanisms are means of power transmission as well as motion transformers. A fourbar mechanism consists mainly of four planar links connected with four revolute joints. The input is usually given as rotary motion of a link and output can be obtained from the motion of another link or a coupler point. Straight line motion from a four bar linkages has been used in several ways as in a dwell mechanism and as a linkage to vehicle suspension. This paper studies the straight line motion obtained from planar four-bar mechanisms and optimizes the design to produce the maximized straight line portion …
