Word Hypothesis From Undifferentiated, Errorful Phonetic Strings, R. Thomas Sellman

Theses

This thesis investigates a dynamic programming approach to word hypothesis in the context of a speaker independent, large vocabulary, continuous speech recognition system. Using a method known as Dynamic Time Warping, an undifferentiated phonetic string (one without word boundaries) is parsed to produce all possible words contained in a domain specific lexicon. Dynamic Time Warping is a common method of sequence comparison used in matching the acoustic feature vectors representing an unknown input utterance and some reference utterance. The cumulative least cost path, when compared with some threshold can be used as a decision criterion for recognition. This thesis attempts …

Efficient Software Implementation Of The Jbig Compression Standard, Craig M. Smith

Theses

JBIG is a new binary image compression standard that is designed to handle both text and halftoned documents. It significantly outperforms the CCITT Group 3 and Group 4 standards especially on halftoned documents. The JBIG standard is based on an arithmetic encoder, and it features adaptive probability estimation, adaptive templates, and three different types of prediction. It also allows either sequential or progressive compression of image data. A brief discussion of information theory is given as it applies to image compression. The JBIG algorithm is described, and several techniques are developed to efficiently implement the algorithm in software. The most …

A Study Of Time And Temperature Variables Affecting Apolipoprotein B-100 On Iodipamide Ethyl Ester Particles, Deborah J. Alberty

Theses

The hypothesis tested in the epitope stability study is that apo B bound to a synthetic core of iodipamide ethyl ester (IDE) particles retain stability, as detected by immunoreactivity of apo B epitopes with two monoclonal antibodies. The mAB 3.01 binds to the carboxy terminal end of apo B-1 00. The mAB T4 binds to the T4 peptide fragment at the amino terminal end of both apo B-1 00 and apo B-48. Stability of LDL-coated IDE was evaluated over 40 days when stored at -20C, 4C and 25C. Stability of reconstituted lyophilized IDE was evaluated over 42 days, starting with …

All approaches discussed in this paper are based on viewing the robot as a sphere . By assuming this , the need to consider the robot's orientation as it moves along a proposed path is eliminated . Another requirement is that …

Retrieval From An Image Knowledge Base, James Janicki

Theses

With advances in computer technology, images and image databases are becoming increasingly important. Retrievals of images in current image database systems have been designed using keyword searches. These carefully designed and handcrafted systems are very efficient given the application domain they are built for. Unfortunately, they are not adaptable to other domains, not expandable for other uses of the existing information and are not very forgiving to their users. The appearance of full-text search provides for a more general search given textual documents. However, pictorial images contain a vast amount of information that is difficult to catalog in a general …

What Happens To A Dream Deferred?, Alan H. Gordon

Theses

I believe that everyone must handle things in their own way to remain true to their goals and themselves. I have strived to stay loyal to this idea during my thesis, because any superficial attempts at representing my views on racial subjects have fallen short of honesty. An honest representation of qany subject cones form the heart, and is a fresh and exciting image. I motivated myself to produce as much work as I was phsically capable of while striving to maintain a high level of aesthetic quality. In order to reduce confusion and convey my ideas clearly, I have …

Optimal Morphological Filters, Vivek Swarnakar

Theses

The design of optimal morphological filters, in the binary or gray scale domain, involves a computationally intense search procedure that, in practice, can be intractable. The present work provides a practical method for optimal morphological filter design that is based on the statistical estimation theory and lattice theory. A link is made between optimal morphological filter and the conditional probability distribution. For a given conditional probability distribution a morphological filter may or may not exist. If a morphological filter exists, then the method designs the one that is optimal among morphological and all other filters. If an optimal morphological filter …

Study Of The Temperature Dependence Of The Intrinsic Viscosity [Nu] For Polystyrene And Poly (Styrene - Co - Maleic Anhydride), Rong Su

Theses

The Mark-Houwink-Sukaroda (MHS) equation [r|J = K Mva is a very important relationship to relate polymer dilute solution's intrinsic viscosity and polymer's viscosity average molecular weight. But for a wide range of polymer (copolymer) - solvent systems, the constant K and exponent a values are usually not sufficiently available. Fox - Flory and Van Krevelen dilute solution theories are employed to correlate K and a values under different temperatures therefore prove that MHS constant K and exponent a are temperature dependent for polystyrene and styrene-co-maleic anhydride. For polystyrene, the exponent a value changes from 0.7165 at 25C to 0.7327 at …

Jan Tschichold: Contrast In Theory, Thérèse Hannigan

Theses

Jan Tschichold was a brilliant typographer who dramatically influenced graphic design and printing with his contrasting theories of design. He began as a proponent of the so-called "new typography" and then pursued the revival of more traditional styles. Because Tschichold's diametrically opposed theories about typography continue to appeal to a large audience, this exhibit of his evolution as a typographer is useful and important. This exhibit is an overview of his writings and typography concentrating on his dramatic stylistic changes. The exhibit is accompanied by a poster, annotated catalog, and descriptive labels.

Suprem-Ii Analysis Of The Phosphorus Planar Diffusion Source Ph 1000n, Paul M. Whalen

Theses

The phosphorus planar diffusion source, PH-1000N, was used to test the ability of the process simulation program SUPREM-H to accommodate solid source diffusion. Spreading resistance analysis and secondary ion mass spectrometry (SIMS) were used to determine the impurity concentration profiles of phosphorus diffused into p-type silicon. Sheet resistance and junction depth data, in addition to the impurity concentration profiles, were plotted against the respective data generated by SUPREM. The surface gas concentration, a parameter requested by SUPREM's input file, was found to have the strongest influence on the program's output. The solid solubility of phosphorus in silicon at process temperatures …

Performance Of Edge Operators Under Varying Imaging Conditions, Ching-Wei Chang

Theses

A method has been devised for performing edge operations with various edge operators under varying imaging conditions and for quantitatively comparing the results of each edge operator. Both computer-simulated targets and real targets are employed, and experiments in both cases showed that the Sobel operator and Kirsch Compass Gradient Mask are better than the Highpass and Laplacian filters in the performance of edge operation.

Investigations On Thin Film Polysilicon Mosfets With Si-Ge Ion Implanted Channels, Luigi Ternullo

Theses

Thin Film Transistors have been fabricated in 0.2 urn thick polycrystalline silicon. NMOS and PMOS devices were fabricated on four groups of substrates. One group was processed with as deposited polysilicon and three of the substrates received high dose implants of Si and/or Ge prior to anneal. The Si implants were designed to amorphize the film by a process known as Seed Selection through Ion Channeling (SSIC), and the Ge was implanted just below the surface to enhance transistor characteristics. Two of the groups, one which received Ge implanted just below the surface and the other no implant at all, …

Application Of Desktop Manufacturing System (Sla) For The Manufacturing Of A Centrifugal Pump Impeller Using Cad (I-Deas), Wasimuddin Azam Muhammad Syed

Theses

Desktop Manufacturing (DTM) systems which combine personal computer, laser and other technologies are being used to sculpt objects from computer generated models created on computer aided design (CAD) workstations. As a member of DTM systems, StereoLithography Apparatus (SLA) transforms 3-dimensional designs into a 3-D output. This can substantially reduce the time required to produce a prototype through the process of photopolymerization. The process involves the transfer of a liquid plastic monomer into a solid polymer by exposing it to ultraviolet light.

Although the process looks productive, inefficiencies can occur, if incorrect parameters are selected before its application for a particular …

The GenSIF framework which is targeted towards very large, distributed, and complex software systems recently has been proposed to accomplish a form of systems engineering and systems development in which the issue of systems integration is considered from the beginning on.

One of the components of GenSIF is domain analysis. Domain analysis leads to the design of a domain model. The specific needs GenSIF has in that area were investigated with an emphasis on domain modeling. Main points addressed in that investigation were the issue regarding the relevant information for the domain modeling process and the required type of domain …

Bragg Reflection Grating Waveguide, Wei Zhong

Theses

Bragg reflection waveguides (BRW) are non-conventional optical guides in which optical confinement is achieved via periodic set of grooves or stratified media along the guiding path. BRW may also serve as optical filters, because of spectral discrimination of the guiding process. A novel UV laser ablation technique was used in this thesis to fabricate periodic metal-clad polymeric waveguides. Spin-on technique was applied to fabricate the waveguide core on glass substrates, evaporation of metal film and selective ablation process defined the optical guides. Various periodicities have been fabricated and the near field patterns have been measured to compare the different guiding …

Mineralization Of 2-Chlorophenol Using A Hollow Fiber Ultrafiltration System In Combination With A Reactor Containing An Immobilized White Rot Fungus, Sheau-Ming Tung

Theses

Phanerochaete chrysosporium, a white rot fungus was immobilized on a packed-bed reactor, and was used to mineralize an aqueous stream contaminated with 50 ppm of 2-chlorophenol. Hollow fiber ultrafiltration membranes (for 5,000 daltons and 10,000 daltons molecular weight cut-oft) were utilized to retain the extracellular enzyme resulting from the immobilized fungus in a recirculation loop outside of the reactor.

It was found here that the concentration of proteins (roughly proportional to the extracellular enzyme releasd by the fungus) does not correlate with the rate of degradation of 2-chlorophenol in the system. The protein was concentrated 1.5 fold in the recycle …

Detection Of Particles And Estimation Of Size Distribution In Process Fluids, Bo Li

Theses

Process fluids may be degraded by large concentrations of suspended particles, formations of gel slugs, or the infiltration of air bubbles. The scattering of ultrasound is dependent upon the relation of the wavelength and the scatterers' dimensions. Relatively large objects are easily detected because of their strong scattering in the short wavelength limit (SWL), but small ones may be missed because of their weak scattering in the long wave length limit (LWL). When the object dimension is comparable with the wavelength of ultrasound (intermediate region), the approximations of both the SWL and the LWL do not apply. The work described …
