Analysis And Applications Of Ftir Systems, Gunjan Navin Doshi

Theses

Fourier Transform Infrared Spectroscopy (FTIR) is a dynamical instrumental technique used in industry for measuring high quality infrared spectra. Over the last 25 years, the increased demand for having an efficient real-time quantitative measurement technique has led to extensive research and development in the field of FTIR Spectroscopy. Through the use of FTIR, sensitivity has increased, size of the smallest sample that can be analyzed has been reduced, and the number of new applications has exploded. In this thesis, an attempt is made to study the principles, theory, instrumentation and applications of FTIR Spectrometry. We survey the working of spectrometer, …

Improving The Run Time Of The Decomposition Algorithm For Fault Tolerant Clos Interconnection Networks Through Swap Re-Ordering, Andrea Laura Mcmakin

Theses

Clos interconnection networks, used in data networks and computing systems, can contain extra switches to be used in faulty conditions. The speed of such fault tolerant Clos interconnection networks is improved through the use these switches in no-fault situations. The network can be represented by a matrix, which is then decomposed using an algorithm, and the switch settings are thus assigned.

The original decomposition algorithm consisted of four element swaps in the following order: wild swap, simple swap, next simple swap, and successive swap. However, by re-arranging these swaps with the simple swap first, followed by the next simple and …

Design, Fabrication And Characterization Of The Infrastructure For A Two Part Non Volatile Ram, Suma Madapur

Theses

The present trend is to be able to develop cheaper and more convenient methods to design and fabricate non volatile RAM that will lead to an alteration of the computer architecture itself This will help replace the DRAM, which the computers currently have in their memory. The proposed NVRAM is designed to overcome the common difficulties faced with the use of ferroelectric materials used in the fabrication of NVRAM. The new idea essentially consists of fabricating the circuitry component separately and the substrate component separately and binding the two with the help of a conducting material. Electrical properties such as …

Modeling And Numerical Analysis Of Beam Matrix Plasma Display System, Jingwu Zhang

Theses

This research investigates a new display device - Beam Matrix Plasma Display Panel (BM PDP). The scan of a PDP in such a system is accomplished through two electrical-beam guns instead of semiconductor switches.

The BM-PDP eliminates the expensive semiconductor switches in the current plasma display device systems. Its drive circuit has only three parts: electron beam guns, resistors and capacitors. During the operation of BM PDP, first a switch cell is turned on by a selection gun (X gun). Then another electron gun (Y gun) emits electrons onto column electrodes and capacitors. When the voltage over the corresponding luminous …

Evaluating The Communications Capabilities Of The Generalized Hypercube Interconnection Network, Sanjay Krishnamurthy

Theses

This thesis presents results of evaluating the communications capabilities of the generalized hypercube interconnection network. The generalized hypercube has outstanding topological properties, but it has not been implemented in a large scale because of its very high wiring complexity. For this reason, this network has not been studied extensively in the past. However, recent and expected technological advancements will soon render this network viable for massively parallel systems.

We first present implementations of randomized many-to-all broadcasting and multicasting on generalized hypercubes, using as the basis the one-to-all broadcast algorithm presented in [3]. We test the proposed implementations under realistic communication …

Design And Implementation Of Generalized Adaptive Neural Filters, Chun Yip Tam

Theses

Generalized Adaptive Neural Filters (GANF) are a class of adaptive non-linear filters. This thesis presents a hardware implementation of GANF. Two designs are considered: the single neuron implementation and the multi-neuron implementation. The GANF design includes the window generator, threshold decomposer, training and filtering unit. The designs are verified through a logic design/simulation tool, Logic Works.

Design Of A Communications Interface For A Very High Performance Computer, Jesse Boyd Zydallis

Theses

PetaFLOPS computing power is the newest goal of Federal Government agencies, in the increasingly active supercomputer field. To obtain this performance goal by the year 2007, sophisticated parallel processing designs are required. To effectively create network interfaces/routers for interprocessor communications in such computer systems, it requires optimal hardware and software codesigns.

An interface is presented for the NJIT New Millennium Computing Point Design, a system that targets 100 TeraFLOPS performance by the year 2005. The router handles store-and-forward switching and wormhole routing for the system.

Building A Secure Intranet, Fred J. Berryman

Theses

This thesis will explain the vulnerabilities of computers in a networking environment and demonstrate proper procedures for building a secure Intranet.

The Internet is built around the concept of open communication. Data is shared around the globe just as easily as it is from one office or cubical to the next. Corporations are skeptical about putting company data on such a public transport mechanism as the Internet, but the tools used on the Internet are exciting and everyone wants to use them. Out of a desire for the best of both worlds, the Intranet was born.

An intranet that has …
