Performance Modeling Of High Data Rate Ring Networks Using Stochastic Petri Nets, Le Zhong

Theses

This thesis has proposed a performance analysis method for Carrier Sensing Multiple Access Ring Network (CSMA) based on Petri net methodologies. The method can offer more accurate results than traditional queuing methods, but less than simulation results. In the CSMA network access protocol is studied in this thesis, when a passing message is detected by a station, it stops transmitting immediately in order to avoid a collision.

A generalized stochastic Petri nets model is made first, then the SPNP package is used to do the analysis. The analysis results show that even at a very heavy load fraction of near …

Calibration Of Photoluminescence Experiment, Chihchuan Daniel Lee

Theses

Photoluminescence in a semiconductor at room temperature is quite difficult to distinguish from the many nonlasing optical lines from the laser, therefore, a blank test is very important. In so doing, the noises of the detector has to be taken into account. The calibration, however, mainly depends on the detector and is less dependent on other components. Instead of using black-body radiation light source and pyroelectric detector, we use globar lamp and PbS detector; because of the difficulty in the former case in doing alignment of optical path (invisible) and operating at a lower signal level from the detector. The …

A Hybrid Low Bit-Rate Video Codec Using Subbands And Statistical Modeling, Ferhat Cakrak

Theses

A hybrid low bit-rate video codes using subbands and statistical modeling is proposed in this thesis. The redundancy within adjacent video frames is exploited by motion estimation and compensation. The Motion Compensated Frame Difference (MCFD) signals are decomposed into 7 subbands using 2-D dyadic tree structure and separable filters. Some of the subband signals are statistically modeled by using the 2-D AR(1) technique. The model parameters provide a representation of these subbands at the receiver side with a. certain level of error. The remaining subbands are compressed employing a classical waveform coding technique, namely vector quantization (VQ).

It is shown …

The Floral Ploy "Pieced, Painted, Printed", Shannon Pfaff

Theses

The purpose of this thesis is to take a complex concept and redefine it visually. The theory of brain evolution has been, and will continue to be in debate both scientifically and spiritually. Since the brain, or the mind, is the center of thought, it seems fitting that a search for unity begin here. Art and science, art and religion, science and religion, are not at opposite ends. Reason and emotion, instinct and intellect, power and surrender, can come together and exist in harmony. It is the goal of this thesis to explore how, through examining the inner workings of …

A Study Of Gray Level Recording Capability For A Reflective Six Bit Desktop Scanner, Julio E. González

Theses

A common problem with CCD sensors is their inefficiency to accurately record gray level information in the shadow range of an image. This problem is magnified on original copy having important detail in the midtone to shadow range. Consequently, when this type of an image is scanned gray levels in the shadow range of the reproduction are not easily discerned. This study examines two areas, the recording consistency across the scanning sensor and the gray level recording for a desktop six bit scanner. The former determined how consistently density information is recorded across the sensor, while the latter determines the …

A Layout Algorithm For Hierarchical Graphs With Constraints, Michael Slade

Theses

A new method is developed for reducing edge crossings in the layout of directed graphs for display. The method will reduce edge crossings in graphs which have constraints on the location or movement of some of the nodes. This has not been available in previously published methods. An analysis of the strategies used to choose rank pairs for edge crossing reduction shows that this choice will dramatically affect the amount of crossings eliminated. This method is directly applicable to the reduction of edge crossings in the general graph.

The Individual Investor : Investment Objectives, Strategies, And Tactics, Clive Walcott

Theses

The individual investor's circumstances and investment behavior have received relatively little attention since it was discovered in the late sixties that he was withdrawing as a direct participant in the American equities market. The first major response to this withdrawal phenomenon was the 1974 Individual Investor Research Project (IIRP). For the first time, the individual investor's circumstances and decision processes were examined directly and not through broad-based trading statistics or portfolio simulations.

This current survey identifies the significant changes in investment objectives, strategies, and tactics since the IIRP. These changes were discovered when seven demographic variables were cross-classified with various …

Introduction Of An Information Feedback Loop To Enhance The Urban Transportation Modeling System, Kyle B. Winslow

Theses

The Urban Transportation Modeling System (UTMS) is a methodology used to estimate urban travel demand. This demand is measured as the volume of traffic that flows through a system of streets and highways. Through the use of traffic assignment software, parts of UTMS have become automated. One of the newest automated processes is the extraction of a subarea from a larger model. This extraction process is important to the local planner because it maintains a linkage from the regional model to the local model and it allows the user to extract an already distributed trip table rather than building one …

A Study Of In Vitro Phase Aberration Measurements In Ultrasonic Imaging, Todd Huck

Theses

Phase aberrations in soft tissues have been shown in previous studies to create disturbing degradations in the point spread function (psf) of ultrasonic phased array imaging systems. These aberrations are caused by spatial velocity fluctuations due to the inhomogeneous nature of soft tissue. Certain time delay corrections are applied to the signal received by each element of a phased array based on the assumption of constant velocity. Small deviations from this assumption in a soft tissue can result in spatial fluctuation in time delay and have a negative effect on the corrected output. The solution is a two step process. …

A Dynamic Model To Study The Influence Of Alpine Ski Boot Characteristics On Heel Retention Force, Elizabeth T. Hsiao

Theses

A dynamic model representing an alpine ski boot under a forward leaning load was successfully developed. This model was based on the equations of motion for the defined system. The intent of this model was to provide an initial, first order investigation of the effect of variations in boot design.
