A Signal Conditioning Approach For The Extraction Of The Oscillatory Petential From The Electroretinogram, Peter Haines Derr

Theses

The oscillatory potential (OP), a signal component of the electroretinogram (ERG), was investigated to determine correlation of the OP and pathological conditions of the inner retina. Large transients characterize the ERG. Such transients stimulate a filter's natural response. Since these responses can co-occur with the OP, a distorted OP will be extracted. A proposed signal windowing and padding technique for conditioning the ERG signal has been implemented for the extraction of a ntnimally distorted OP.

Windowing is used to capture only the OP period. The windowed ERG signal is then signal conditioned to generate initial values for the filter's state …

Production Of Submicron Aerosols By Powder Depressurization, Amit Haryani

Theses

Disaggregation of dry powders in shear flow has limitations in producing submicron particles. This study explores a new method for the production of submicron particles by the depressurization of powder aerosols. The depressurization mechanism is based on the rapid depressurization of the aggregated powder through a specially designed nozzle. As the pressure suddenly decreases from very high values inside the aggregates (800 psi) to ambient at the surface of such aggregates, disaggregation takes place due to the force exerted by the gas escaping through their pore structure.

he effect of various process parameters, namely: nozzle diameter, pressure and pretreatment with …

Design Of Components For A Generic Microprocessor Architecture, Pradnesh R. Mohare

Theses

Role Of Sympathovagal Imbalance In Syncope Using Heart Rate Variability Analysis, Jayadeep Krishnah Unni

Theses

One of the common and challenging problems confronting the physician in clinical practice is recurrent syncope. Despite extensive evaluations, the causes of these cases Of syncope are not found in more than 40% of the patients.

It is thought that most patients who experience unexplained syncope do so because of transient, unpredictable episodes of vasovagally mediated hypotension and bradycardia. It is hypothesized that impaired inhibition of parasympathetic tone during stress accompanies the development of syncope. Head-up tilt table testing reportedly provokes vasovagal episodes effectively in susceptible persons.

This study attempts to explain the role played by the sympathetic and parasympathetic …

A Guide To Image Preparation For Multiple Media, Ai-Leen Chiu

Theses

With the advanced technology in this information requisite world, the way of communication has been changed into using multiple media. People use different media to publish their ideas, not just on paper. The same information may be presented in different formats because of different purposes or situations. However, each of the four major media (print, Web, CD-ROM, and video) has different capabilities for displaying image information. Images optimized for one will not necessarily work well with the others. It happens all the time that people spend much time remanipulating an image which has already been made for another media. For …

Interactive And Zero-Knowledge Proofs, Molli Noland

Theses

An interactive proof involves two parties, the prover and the verifier. The goal of the proof is for the prover to convince the verifier that some instance of a decision problem is true. A zero-knowledge proof is an interactive proof where the only information learned by the verifier of the proof is the outcome of the proof. This thesis contains a theoretical overview of interactive and zero-knowledge proofs and describes experiments with implementations of some of them. Two examples of interactive proofs from number theory are given, a protocol for quadratic non-residues and a protocol for subgroup non-membership. The third …

Equine Osteoarthritis: A Comparison Of Type 1 And Type 2 Conditions, Wendy Chadbourne

Theses

In what originally began as research to answer my own questions about osteoarthritis, I learned as much as I could from reading anatomy, veterinary, and physiology books. I had to look in many places to find all the answers I wanted. The books that provided the best visual information lacked text to explain the images, and the books that provided the best text definitions usually provided simplified illustrations or very confusing clinical photographs. While trying to unite the best images with the best text explaining what was going on, an idea was formed. I decided to combine clear images with …

The Design And Implementation Of A Virtual Type Specimen, Keli Mccreadie

Theses

Typesetting and typography have become misunderstood terms, if not obsolete, due to the proliferation of computers. Since every computer user has access to a myriad of typefaces and the ability to modify type through software, the true qualities of many typefaces have become unrecognizable. Therefore, it is incumbent upon people to seek out the information necessary to be competent in the area of design and typography. A well-designed type specimen is the first place to start for a user to reference typographic terminology and rules. Technical characteristics of typefaces such as tracking, font metrics, leading and unique recognizable characters could …
