A Genetic Algorithm Approach To Automating Satellite Range Scheduling, Donald A. Parish

Theses and Dissertations

Satellite range scheduling involves scheduling satellite supports in which a satellite and a specific remote tracking station communicate with each other within a specified time window. As the number of satellite supports continue to increase, more pressure is placed on the current manual system to generate schedules efficiently. Previous research efforts focused on heuristic and mixed-integer programming approaches which may not produce the best results. The objective of this research was to determine if a genetic algorithm approach to automating the generation of 24 hour schedules was competitive with other methods. The goal was to schedule as many supports as …

Integrated Embedding Optimization Applied To Salt Lake Valley Aquifers, A. Gharbi, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

The embedding optimization modeling approach is adapted to aid sustainable groundwater quantity and quality management of complex nonlinear multilayer aquifers. Implicit block-centered finite difference approximations of the quasi three-dimensional unsteady flow equation and Galerkin finite element approximations of the two-dimensional advection-dispersion transport equation are embedded directly as constraints in the model. Also used are nonlinear constraints describing river-aquifer interflow, evapotranspiration, and vertical flow reduction due to unconfinement. These circumvent use of large numbers of integer variables. The use of both linear and nonlinear formulations in a cyclical manner reduces execution time and improves confidence in solution optimality. The methodology is …

Aqueous Absorption Of Nitrogen Oxides Induced By Oxychlorine Compounds : A Process Development Study For Flue Gas Treatment, Chen-Lu Yang

Dissertations

The use of chlorine (Cl₂), sodium hypochlorite (NaClO), and sodium chlorite (NaClO₂) as oxidizing agents to promote the absorption of nitric oxide (NO) from gas streams has been investigated in the Gas Scrubbing Laboratory of New Jersey Institute of Technology since 1988. The first step of this project had been to screen out the best scrubbing medium for nitric oxide removal from flue gases. The most successful oxidizing agent was found to be sodium chlorite in acidic aqueous solution. The screening results have been accepted for publication in Chemical Engineering Communications. A sodium chlorite containing aqueous …

Application Of The Wavelet Transform To Biomedical Signals, Karl O. Hauck

Theses

The basic concepts and fundamentals of the wavelet signal representation were examined. The orthonormal wavelet was selected for this project after being compared to various types of wavelets. The orthonormal wavelet was chosen due to the equal time and frequency resolution exhibited in the wavelet coefficients. Programs were written in Matlab to implement the orthonormal wavelet in developing wavelet coefficients for a given signal. The programs include the conditions for an orthonormal wavelet in and which produce the wavelet filters g(n) and h(n). The wavelet filters were then incorporated into another program that applied Mallat's multiresolution algorithm for a given …

Design, Construction, And Operation Of Water Treatment Plant Residual Monofills, Haitao Bian

Theses

Due to the stringent environmental regulations, landfilling becomes the most viable option for ultimate disposal of water treatment plant (WTP) residues. At present, most states apply the regulations for municipal solid waste (MSW) landfills to the landfilling of WTP residues. This is too stringent since the WTP residues are not hazardous. Therefore, development of suitable criteria for WTP residual monofills is necessary and urgent.

A set of environmental and geotechnical experiments was conducted to characterize WTP residues. It can be concluded that very little leachate will be produced and migration of leachate is unlikely. Also it was noted that insignificant …

Modeling Arsenic Transformation In Clay Soils, Chao-Yi Chung

Theses

This project is designed to estimate the possible transformation forms of arsenic in clay soil. A computer model was established to simulate arsenic transformations. The amount of arsenic species adsorbed, dissolved, and the predominant soluble species are calculated by the model, which is mainly based on the Freundlich adsorption isotherm, solubility data collected by Keaton and Kardos, and pH-Eh diagram established by Ferguson and Garvis. The computer language used is Turbo PASCAL version 5.5.

The clay soil environment is considered to be in standard state: 25°C 1 atm. Environmental factors of the soil system which are accounted for by the …

Concurrent Engineering And Design For Manufacture In The Medical Device Industry, Martin A. Mathelier

Theses

Concurrent Engineering (CE) is an approach to product development in which engineers work on design and manufacturability at the same time. The ultimate goal of concurrent engineering is to reduce the time-to-market while improving quality. This thesis goes into details about the tools necessary to achieve successful product development in the Medical Device Industry. The novelty of this thesis is not in the tools themselves but rather in the way that they are applied to the medical device industry. The need for the CE approach is of utmost importance because of the vast competition in the medical device industry.

National Research and Education Network(NREN) is a first step in the process of building a National Information Infrastructure(NII). NII will ultimately lead to Broadband Integrated Services Digital Network(B-ISDN), a network which will support global exchange of voice, data, images and video.

NREN will evolve out of present National Science Foundation Network (NSFNET), also known as Interim NREN. At present NSFNET operates at 45 MBits/sec. By 1996, there are plans to boost the data rate to 155 MBits/sec and to 620 MBits/sec by the turn of century.

In this thesis, present actual NSFNET is simulated using software simulation tool Networkll.5. The …

Development Of A Non-Intrusive Particle Motion Tracking Technique For Granular Flow Experiments, Jerry R. Volcy

Theses

Implementation aspects of monitoring the position and orientation of a one-inch diameter particle in space non-intrusively based on the principle of magnetic induction coupling are discussed. A radio-transmitter embedded within the particle induces voltages in receiver antennae. Position and orientation of the particle are deciphered from these voltages. A previously developed math model that predicts the voltage induced in an antenna given the position and orientation of the transmitter with respect to the antenna as well as the numerical techniques used to obtain the inverse solution of computing position and orientation from a given set of voltages are used.

Measurement Of Heart Rate Variability Using Correlation Dimension And Entropy, Su Zhang

Theses

Heart rate variability regulation is controlled by the autonomic nervous system. Disorders of the autonomic nervous system may cause the loss of heart rate variability. Two new approaches, correlation dimension and entropy, based on ideas from nonlinear dynamics, have been applied to studying heart rate variability. The correlation dimension measures the extent of correlation between the data points. The entropy measures the amount of information needed to specify the state of a system. The interbeat interval signal (1BI) from eighteen subjects (nine normal controls and nine patients with Chronic Fatigue Syndrome (CFS) ) have been analyzed and compared. The results …

Contour Extraction From Hvem Image Of Microvessel Using Active Contour Models, Manping Xiao

Theses

This thesis reports the research results on automatic contour extraction from high voltage electron microscope (HVEM) image of thick cross section montages of small blood vessels. The previous work on this subject, which was based on the conventional edge detection operations combined with edge linking, has proven inadequate to describe the inner structural compartments of microvessels. In this thesis, an active contour model (commonly referred to as "Snakes") has been applied to advance the previous work. Active contour models have proven themselves to be a powerful and flexible paradigm for many problems in image understanding, especially in contour extraction from …

Intergranular Corrosion-Fatigue Failure Of Cobalt-Alloy Femoral Stems. A Failure Analysis Of Two Implants, Jeremy L. Gilbert, Christine A. Buckley, Joshua J. Jacobs, Kim C. Bertin, Michael R. Zernich

Biomedical and Chemical Engineering - All Scholarship

Two modular hip implants with a cobalt-alloy head and a cobalt-alloy stem were retrieved after a fracture had occurred in the neck region of the femoral component, eighty-five and seventy months after implantation. Both implants failed less than one millimeter distal to the taper junction between the head and the stem (outside of the taper). The fracture surfaces of the implant were investigated with the use of scanning electron microscopy, to determine the nature of the failure process. The fractures occurred at the grain boundaries of the microstructure and appeared to be the result of three factors: porosity at the …

Acceptable Risk: A Conceptual Proposal, Baruch Fischhoff

RISK: Health, Safety & Environment (1990-2002)

Challenging the "de minimis risk" concept, Dr. Fischhoff argues that risks ought not to be considered apart from a particular technology's benefits. He argues, too, that the acceptability of particular kinds of risks should not be determined without considering the views of all persons who may be exposed. Finally, building upon the "reasonable person" construct, he suggests ways those goals might be achieved.

Adsorption-Dissolution Reactions Affecting The Distribution And Stability Of Coii Edta In Iron Oxide-Coated Sand, James E. Szecsody, John M. Zachara, Patrick Bruckhart

United States Department of Energy: Publications

The time-variant chemical behavior of Co^IIEDTA (and other metal-EDTA complexes) was investigated in suspensions of iron oxide-coated sand to identify equilibrium and kinetic reactions that control the mobility of Me^IIEDTA complexes in subsurface environments. Batch experiments were conducted to evaluate the adsorption as a function of pH, concentration, and time and to quantify the rate-controlling step(s) of dissolution of the iron oxide by EDTA complexes. Ionic Co²⁺ exhibited typical cation-like adsorption, whereas Me^IIEDTA adsorption was ligand-like, increasing with decreasing pH. Adsorption isotherms for all reactive species exhibited Langmuir behavior, with site saturation occurring …

Interaction Of Hydrophobic Organic Compounds With Mineral-Bound Humic Substances, Ellyn M. Murphy, John M. Zachara, Steven Smith, Jerry Phillips, Thomas Wletsma

United States Department of Energy: Publications

The sorption of hydrophobic organic compounds (HOC) on mineral-associated peat humic acid (PHA) was evaluated under different pH and electrolyte regimes. Relative size distribution measurements indicated that PHA was “coiled” in solution at high ionic strength (I) and elongated at low I. The sorption of PHA to hematite and kaolinite varied with I and electrolyte cation, suggesting that the configuration of the humic acid in solution influenced its structure on the mineral surface. The sorption maxima for PHA on kaolinite indicated that PHA occupies twice the mineral surface area at low I (0.005) as that observed at …

Light, Chlorophyll, Carboxylase Activity And Co2 Fixation At Various Depths In The Chlorenchyma Of Opuntia Ficus-Indica (L.) Miller Under Current And Elevated Co2, Park S. Nobel, Muyi Cui, Alvaro A. Israel

United States Department of Energy: Publications

Mature cladodes of Opuntia ficus-indica (L.) Miller have a thick chlorenchyma (about 4 mm) with a relatively high chlorophyll content (0-65 g m^-2), suggesting that light may be greatly attenuated and hence CO₂ fixation negligible in the inner part of this tissue. Indeed, blue light (400-470 nm) and red light (670-685 nm) were 99% attenuated in the outer 2 mm of the chlorenchyma when the cladodes developed under both current and elevated CO₂ concentrations. Nevertheless, the nocturnal acidity increase and ¹⁴C accumulation following a brief exposure to ¹⁴CO₂ at night decreased only 22 …

Industrial Uses Of Soyoil: A Market Analysis, Janice L. Callum

Industrial Agricultural Products Center: Publications and Information

Industry Structure
Lubricants' base oil production is virtually controlled by five, vertically integrated, multi-national companies. Their market shares are large enough to permit strong influence over the entire industry and to render competition ineffective. It will be difficult for new firms to enter the lubricant's industry and compete successfully with these entrenched firms. The lubricants market is large. The market is dominated by petroleum based, mineral oil products. Projected market growth is minimal, and worldwide supply is ample. Growing environmental awareness and the prospect of stringent regulations regarding petroleum products use have spurred renewed interest in the manufacture of vegetable …
