S.57392, Christine Lo

Theses

The idea of creating and writing a thesis loomed before me as an awesome task I would never be able to bring to fruition. However, the time came when I had to sit down and seriously ask myself how I would like to spend the remainder of my time here at RIT. Regretfully, I cannot say that there was a burning passion within me. I began to approach the thesis topic and asked myself, "What is out there that has yet to be fully explored?" Looking through several articles and speaking with a diverse group of people, I became involved …

Characterization Of Three-Dimensional Shear Flows, Kurra Bhaswan

Theses

This work investigates techniques to analyze and characterize the presence of microstructure in moderately dilute three-dimensional shear flows. In three dimensional shear flows, a distinct structure develops as the coefficient of restitution is lowered with the particles exhibiting a strong tendency towards the formation of clusters. There exists a need to automatically detect and characterize this microstructure in the given flow. Several methods are examined for effective characterization of the microstructure. The techniques employed are based on the classification of the data based on the properties of the Voronoi diagram constructed from the positional parameters of the two-dimensional slices of …

A Parallel Processing Architecture For Dqdb Protocol Implementation, Nilesh Vinubhai Gandhi

Theses

The high bandwidth transmission links, which have been provided by the advances of Fiber Optics Technology, reduce drastically the packet transmission times and place new demands on the nodal protocol processing. Segmentation and reassembly of packets, computation of checksums, introduction of source and destination addresses, etc., must be performed extremely fast in order to prevent node processing from becoming the bottleneck of the transmission. Parallel processing enables the execution of the previous tasks on multiple packets simultaneously and therefore has the potential of addressing the issue of fast node processing successfully. In this thesis we focus on the Medium Access …

Agitation Requirements For Complete Liquid Dispersion In Liquid-Liquid-Gas Systems, Emad Ahmad Abu-Hakmeh

Theses

A number of studies have been published in the literature on the determination of the agitation intensity at which two immiscible liquids become completely dispersed in mechanically agitated vessels. However, no information is currently available on the agitation intensity required for the complete dispersion of two liquids in the presence of an additional gas phase. Therefore, the main objective of this study was to experimentally determine the minimum agitation speed for complete liquid-liquid dispersion, N_cd, in liquid-liquid-gas systems as a function of gas flow rate, impeller type, impeller size, and impeller off-bottom clearance. The minimum agitation speed was …

Traffic Management Of A Satellite Communication Network Using Stochastic Optimization, Ambalavanar Arulambalam

Theses

The performance of nonhierachial circuit switched networks at moderate load conditions is improved when alternate routes are made available. However, alternate routes introduce instability under heavy and overloaded conditions, and under these load conditions network performance is found to deteriorate. To alleviate this problem, a control mechanism is used where, a fraction of the capacity of each link is reserved for direct routed calls.

In this work, a traffic management scheme is developed to enhance the performance of a mesh-connected, circuit-switched satellite communication network. The network load is measured and the network is continually adapted by reconfiguring the map to …

Attachment Systems For Curtain Wall Construction And Maintenance Requirements, Peter S. Donaghy

Theses

Curtain Wall construction has become a familiar and widely used method for enclosing structures. Since the 1950's this type of enclosure has become increasingly the most popular choice of Designers and Builders. During this period of development, however, acceptable and uniform building standards have not evolved to create adequate quality control.

This thesis investigates some of the design requirements of Curtain Walls, in particular the attachment system, and the maintenance costs that are directly related to the attachment system and the consequences of such failures.

Computer Assisted Molecular Modeling Of Thymidine Nucleoside Analog Inhibitors Of Hiv-1 Reverse Transcriptase, Mark A. Fisher

Theses

An active analog approach to receptor mapping was used to identify the three dimensional structural characteristics associated with a series of thymidine nucleoside analog inhibitors of HIV-1 reverse transcriptase (RT) that may be essential for their activity. Atomic substitutions at the 5 and 3' positions of nucleoside analogs confer global structural and electrostatic changes that result in either increased or diminished inhibitory activity. From a structural perspective, the activity differences can be attributed to the presentation of select atoms in three dimensional motifs that are common to all active compounds and absent or distorted in inactive/poorly active compounds.

The identification …

Object Oriented Design Of Petri Net Simulator, Himanshu Juneja

Theses

Petri nets are highly useful for modeling discrete event dynamic systems. The objective of this effort is to develop a tool for drawing, editing and simulating Petri nets using object oriented programming on a standard platform. The object oriented approach was chosen because of its code reuse and extendability features which simplify the task of adding features to the tool as the model evolves. The design stresses on modeling of the problem by objects which closely relate the system design with the implementation.

C++ is used for implementing the object oriented design, and the XView toolkit is used for building …

Simplification Of The Generalized Adaptive Neural Filter And Comparative Studies With Other Nonlinear Filters, Henry Steven Hanek

Theses

Recently, a new class of adaptive filters called Generalized Adaptive Neural Filters (GANFs) has emerged. They share many characteristics in common with stack filters, include all stack filters as a subset. The GANFs allow a very efficient hardware implementation once they are trained. However, there are some problems associated with GANFs. Three of these arc slow training speeds and the difficulty in choosing a filter structure and neural operator.

This thesis begins with a tutorial on filtering and traces the GANF development up through its origin -- the stack filter. After the GANF is covered in reasonable depth, its use …

Investigation Of Reaction Kinetics Of Hydrogen Chloride With Calcium Oxide By Fourier Transform Infrared Spectroscopy, Maosheng Li

Theses

The kinetics of HCl reaction with CaO was investigated over the temperature range of 148 to 400 °C. A thin film of CaO was deposited on quartz wool and used as the sorbent. The HCl concentration was maintained uniformly in the closed system with a circulating pump in order to minimize the effects of the bulk mass transfer and pore diffusion. The HCl concentration was continuously monitored in a FT-IR cell and the HCl and H₂O spectra were collected automatically by GC software at 1.2 second intervals. In this way, fewer errors were introduced into the system. The …

Local Stress Factors Of Pipe-Nozzle Due To Radial Load, Circumferential And Longitudinal Moments, Junyu Lin

Theses

This thesis presents a series of stress factor data which provide more detailed information for the calculation of local stresses at the nozzle region, as well as the pipe region, of a pipe-nozzle intersection, subjected to an external radial load, circumferential bending moment, and longitudinal bending moment, respectively.

The pipe and nozzle thicknesses are assumed to be identical. Numerical solutions are obtained through the use of the finite element method. In obtaining the numerical solutions via ANSYS, the quadrilateral element is used to simulate the thin shell pipe-nozzle geometries. The local stresses, at eight different points on both the pipe …

Design Of Mask For Striped Filters And Thin-Film Multi-Layer Emissivity Modeling For Multi-Wavelength Imaging Pyrometer, Jitesh Navinchandra Shah

Theses

Multi-Wavelength Imaging Pyrometry (M-WIP) measures thermal radiation of any target (color or gray) in multiple narrow-spectral-regions and can simultaneously determine target temperature and emissivity. One approach for measuring radiation at multiple wavelengths using a 320X244 element Pt-Si SBD infrared camera is to use narrow-band striped filters deposited on a transparent substrate with proper alignment. The major focus of this thesis was the design of a four layer mask for investigating the feasibility of defining three-wavelength striped filters compatible with focal plane array. This mask design allows twelve distinct narrow band striped filter geometries and four test-patterns on a 4-inch silicon …

Scanning Ratios For Desktop Imaging, Mike Beaulieu

Theses

Users of desktop scanning technology are conscious about the quality the image detail reproduction. Repeatability and accuracy are based on certain standards. Established scanning procedures for charged couple device (CCD) desktop scan ners are primarily influenced by the Nyquist Criterion which states that an image must be sampled at twice the frequency of the line screen ruling that will be used to print the final image. These "rules of thumb" appear in many techni cal and trade publications that are consulted by the printing industry in order to insure the quality of printed products. Quality is not the only factor …

Laboratory Investigation Of The Effect Of The Dampening Solution On The Loss Of Surface Strength Of Coated Paper, Chung-Ni Liu

Theses

Wet pick is thought to be caused by the presence of water used in lithography. The quantity of the wetting fluid, surface tension of the wetting fluid and the time interval between wetting and printing were tested to see if they affect the paper surface strength. Two rolls of web paper are pre-sampled from the RIT press room. One was found to exhibit the problem of wet pick while the other did not exhibit this defect. These papers were tested on the IGT Printability Tester in a manner similar to that predicted on press when a moisture film of 0.2 …

Infrared Symbolic Scene Comparator, Thomas G. Servoss

Theses

Infrared image analysis has become a very popular subject of study. Situations as recent as the Gulf War have proved the advantages, and therefore the need, of having not only the proper imaging equipment but the training and expertise to use that equipment. To date, there are few tools that analysts can use to educate themselves and the operators of the state-of-the-art imaging equipment. There are even fewer tools that provide the flexibility to control nearly every aspect of infrared imaging phenomena. Several pre-existing and a few new remote sensing sub-systems have been combined to create an extremely user-friendly infrared …

Investigation Into Optimal Rh(Iii) Deopant Placement In Silver Bromide Emulsions, David A. Telep

Theses

An optimal rhodium (III) doping scheme for silver bromide emulsions was sought which maximized emulsion speed loss, emulsion contrast and coated emulsion stability. Experimental results showed that the photographically active rhodium complex must be co-precipitated with the silver bromide in order to achieve a sensitometric modification of the final emulsion. This dopant induced sensitometric modification was not stable and decayed with time.

Fracture Of Cementitious Composites, Sira Tindukasiri

Theses

Studies in fracture mechanics of concrete use a testing setup which tends to include unacceptably large errors in deflection measurements. Recent work reported by Kim [3] has proposed a new testing setup to eliminate these errors and consequently produce better determinations of fracture parameters.

The error which occurs most frequently is in the measurement of the load-line deflection. Until recently, the way this measurement has been made, using a dial gauge or LVDT (Linear Variable Differential Transformer) to measure the deformation between the center of the specimen and the frame, includes the crushing of the concrete surface at the supports …
