Multi-Lifecycle Assessment Design Tools And Software Development, Ji Jin

Theses

This thesis introduces the concept of Multi-lifecycles and a Multi-lifecycle assessment (MLCA) methodology for evaluating the energy consumption and environmental emissions of a product. MLCA quantifies materials, energy, and environmental burdens associated with end-of-life options, as well as obtains the value of returning parts and materials back to use, through demanufacturing, reengineering and remanufacturing.

A Multi-lifecycle Assessment software is developed as a tool to implement MLCA methodologies. By this software, one can practice a full life-cycle analysis on a product, or compare the environmental impacts of different products. Detailed designs on MLCA software including the databases, user interfaces, and algorithm …

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

Theses

The objective of this thesis was to develop a generic microprocessor design that can be adapted to many of the existing 16 bit microprocessors. Common features of various microprocessors were used to develop the design of many generic components which can then be used to design the required microprocessors instead of custom-designing each one of them separately. The components were designed using a CISC based micro-programmed design approach as that was more suitable in terms of design and verification time for generic implementation. The generic parts designed include the Register File for temporary data storage, the Effective Address Calculator that …

Design, Implementation, And Evaluation Of A Shared-Memory Parellel Processing System (Smpps), Eric H. Staub

Theses

As technology reaches its limits of improvements in microprocessor processing speeds, scientists and engineers have to find viable solutions to meet ever-increasing demands for faster processing speed. One such solution is parallel processing. No longer does one have to wait on sequential operations. A specific task can be split in sub-tasks that can run simultaneously, thus reducing the overall execution time of the task.

The design and implementation of these systems is crucial to the effectiveness of parallel systems. A dual-processor SMPPS was designed and implemented in order to demonstrate how multiple processors are a viable solution to increasing the …

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 …

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, …

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 …

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.

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 …

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.

Automatic Surface Mount Solder Joints Inspection, Zhu Liu

Theses

This thesis reports the research results on automatic inspection of solder joints on printed circuit boards. The previous work on this subject has been advanced significantly in the following three aspects. With the support of AT&T Bell Lab, the most updated surface mount solder joints are inspected in this work instead of larger simulation solder joints or traditional through hole solder joints in the previous work. A small set of features is extracted for surface mount solder joints in both infrared and visual light inspection. A new image processing software named Khoros has been applied to improve the quality of …
