The Siting Of Regional Sanitary Landfills Or Facilities For Municipal Solid Waste In The Upper Southern Region Of Thailand, Jantira Duangsai

Theses

The pollution problem from municipal solid waste in Thailand is serious. Population growth and rapid economic expansion have resulted in a significant increase in the quantity of solid waste. Inadequate provisions for waste collection, shortages of disposal equipment, and the inability of the responsible agencies to find appropriate disposal sites, also are major causes of the present problems. The environmental impacts that result from unsanitary disposal sites have become a serious public concern across the country.

Environmentally protective and publicly acceptable siting of regional sanitary landfills or facilities for municipal solid waste management in the upper southern region of Thailand: …

Comparative Molecular Field Analysis (Comfa) Of Protonated Methylphenidate Phenyl-Substituted Analogs, Kathleen Mary Gilbert

Theses

Protonated methylphenidate (pMP) and several phenyl-substituted pMP analogs were analyzed using Comparative Molecular Field Analysis (CoMFA) to develop a pharmacophore for dopamine transporter (DAT) binding. This research is a part of an interdisciplinary study on using methylphenidate (MP) analogs to block the binding of cocaine to the DAT as a treatment for addiction.

A random search conformational analysis using key pMP torsional angles was performed to create conformer families representing possible bioactive conformations. The lowest energy pMP conformer of each family was used as a template to create phenyl-substituted pMP analogs.

Partial least squares analysis was used to determine the …

Mechanical Properties And Stress-Strain Behavior Of High Performance Concrete Under Uniaxial Compression, Pornchai Jiratatprasot

Theses

Many recent innovations in advanced concrete materials technology have made it possible to produce concrete with exceptional performance characteristics. High performance concrete (HPQ is defined as concrete that meets special performance and uniformity requirements that cannot always be achieved routinely by using conventional materials and normal mixing, placing, and curing practices. The importance of HPC to structural engineering is unquestionable. However, HPC is a relatively new material. Some results of research on conventional concrete are not entirely applicable. In this experiment, the main mechanical properties of HPC including compressive strength, modulus of elasticity, and Poisson's ratio were investigated and compared …

Attack Visualization For Intrusion Detection System, Mohammad A. Rabie

Theses

Attacks detection and visualization is the process of attempting to identify instances of network misuse by comparing current activity against the expected actions of an intruder. Most current approaches to attack detection involve the use of rule-based expert systems to identify indications of known attacks. However, these techniques are less successful in identifying attacks, which vary from expected patterns. Artificial neural networks provide the potential to identify and classify network activity based on limited, incomplete, and nonlinear data sources. Presenting an approach to the process of Attack visualization that utilizes the analytical strengths of neural networks, and providing the results …

Hyperbolic Position Location Estimator With Tdoas From Four Stations, Sreeram Potluri

Theses

This thesis presents a detailed derivation of a set of equations needed to locate the three dimensional position of a mobile given the locations of four fixed stations (like a global positioning system (GPS) satellite or a base station in a cell) and the signal time of arrival (TOA) from the mobile to each station. From these derived equations, a synthesizable VHDL model was developed and simulated using IEEE numen*c_std package. All the inputs and outputs were described by 32 bit vectors. From the simulations, it was observed that in the best case the mobile position was off by I …

Placing Servers In Overlay Networks, Sherlia Shi, Jonathan Turner

All Computer Science and Engineering Research

Overlay networks are becoming a popular vehicle for deploying advanced network services in the Internet. Overlay networks are implemented by deploying service nodes at suitably chosen sites in the network. Service nodes communicate with users through the commodity Internet, while among themselves, they may use either the commodity Internet or dedicated channels. The number of distinct service nodes has a big influence on the operational cost of an overlay network; meanwhile, the distance between service nodes and end users has a big influence on the quality of the service. In this paper, we study the problem of how to optimally …

Consequence Of Superfluidity On The Expansion Of A Rotating Bose-Einstein Condensate, Mark Edwards, Charles W. Clark, P. Pedri, L. Pitaevskii, S. Stringari

Physics & Astronomy: Faculty Publications

We propose an easily detectable signature of superfluidity in rotating, vortex-free gaseous Bose-Einstein condensates. We have studied the time evolution of the expansion of such a condensate after it is released from the confining trap. We find that if such a condensate is not initially rotating, then at some moment it will instantaneously achieve a circular cross section. If the condensate is initially rotating its irrotational flow and the conservation of angular momentum prevent the released condensate from attaining a circular cross section, since the instantaneous moment of inertia is then proportional to the asymmetry of this cross section.

Nontunneling High-Order Harmonics From Ultra-Intense Laser-Driven Tightly Bound Systems, S. X. Hu, Anthony F. Starace, W. Becker, W. Sandner, D. B. Milosevic

Anthony F. Starace Publications

High-order harmonic emission is investigated by numerical solution of the weakly relativistic, two-dimensional Schrödinger equation for the case of ultra-intense laser-driven tightly bound systems (for example, multiply charged ions such as O⁷⁺ exposed to laser fields of the order of 10¹⁸ W cm^-2 at 248 nm). In contrast to their usual substantial decrease, the low-order harmonics having an energy less than the ionization potential exhibit a high efficiency (i.e. intense) plateau with a well defined cutoff. The shape of this plateau is found to depend on the shape of the binding potential. A classical “surfing” mechanism for …

Short-Term Community Based Dune Management Activities On A Highly Developed Coast In New Jersey, Stacy Mccormack

Theses

Recently, local governments have started to realize the effectiveness of dune building as a form of hazard mitigation and have engineered dunes for this purpose. This study evaluates dune management at the local level; specifically, short term management practices, physical constraints, dune management participants, and sources of guidance. A review of municipal regulations, topographic surveys, and interviews with local officials were conducted in four New Jersey communities: Belmar, Spring Lake, Sea Girt and Manasquan. The results of this study indicate that dunes were established as part of local hazard mitigation planning in response to the 1992 storm, and topographic surveys …

Simulation And Close-To-Optimal Algorithm For The Static Load Balancing Of A Network Of Heterogeneous Processors, Mark G. Steiner

Theses

A close-to-optimal linear programming-based algorithm for the static load balancing of a network of heterogeneous processors is described and implemented. Experimental results suggest that the amount of time required by the implementation of the algorithm to balance the loads of the servers as a function of the number of servers has polynomial complexity.

A Real Time Frequency Analysis Of The Electroencephalogram Using Labview, Rupal Patel

Theses

The use of the Electroencephalogram (EEG) for diagnosis of brain related diseases is becoming a popular technique in the clinical and research environment. To achieve accurate reading of EEG, signal representation and classification becomes extremely important. The goal of this project was to develop a basic software program for acquiring and online processing of the electrical activity recorded from the brain. A program was developed using the LabVIEW programming software by National Instruments. Basic hardware components recorded the EEG signal and a software component divided the data into delta, theta, alpha and beta bands in the frequency domain. Emphasis was …

A Comparison Of Potential Labor-Saving Sampling Methods For Assessing Large Mammal Damage In Corn, Richard . M. Engeman, Ray T. Sterner

United States Department of Agriculture Wildlife Services: Staff Publications

Accurate estimation of crop damage by wildlife often requires labor-intensive sampling procedures. Variable area transect (VAT) sampling has been identified as a potential labor-saving alternative to quadrat sampling. We fully enumerated all damaged corn plants in a field to assess accuracy of sampling by small quadrats 5m long by one or two row-widths, and by VAT sampling with searches from random starting points to the 3rd, 4th, 5th, and 6th damaged plant. Two widths for strip transects also were considered for VAT sampling: one and two crop rows. Two analytical formulae were considered for the VAT data. Thus, 18 estimates …

Observation Of Anomalous Spin-State Segregation In A Trapped Ultracold Vapor, Dwight L. Whitaker, H. J. Lewandowski, D. M. Harber, E. A. Cornell

Pomona Faculty Publications and Research

We observe counterintuitive spin segregation in an inhomogeneous sample of ultracold, noncondensed rubidium atoms in a magnetic trap. We use spatially selective microwave spectroscopy to verify a model that accounts for the differential forces on two internal spin states. In any simple understanding of the cloud dynamics, the forces are far too small to account for the dramatic transient spin polarizations observed. The underlying mechanism remains to be elucidated.

Airborne Sampling Of Aerosol Particles: Comparison Between Surface Sampling At Christmas Island And P-3 Sampling During Pem-Tropics B, Jack E. Dibb, R. Talbot, Garry Seid, C. E. Jordan, Eric Scheuer, Elliot Atlas, Nicola J. Blake, D R. Blake

Earth Sciences

Bulk aerosol sampling of soluble ionic compounds from the NASA Wallops Island P-3 aircraft and a tower on Christmas Island during PEM-Tropics B provides an opportunity to assess the magnitude of particle losses in the University of New Hampshire airborne bulk aerosol sampling system. We find that most aerosol-associated ions decrease strongly with height above the sea surface, making direct comparisons between mixing ratios at 30 m on the tower and the lowest flight level of the P-3 (150 m) open to interpretation. Theoretical considerations suggest that vertical gradients of sea-salt aerosol particles should show exponential decreases with height. Observed …

Potent Enantioselective Auxin: Indole-3-Succinic Acid, Daniel W. Armstrong, Yan Song Liu, Lingfeng He, K. Helen Ekborg-Ott, Charles L. Barnes, Charles F. Hammer

Chemistry Faculty Research & Creative Works

Low levels of synthetic auxins are used as root growth promoters for a wide variety of botanicals. When properly used, they can produce earlier and more prolific root growth. Indole-3-succinic acid (ISA) is a chiral compound that can be synthesized as a racemate. Its enantiomers were resolved by both chromatography and diastereomeric crystallization. The absolute configuration of each enantiomer was determined by X-ray crystallography and then tested for auxin activity. The relative effectiveness of the ISA enantiomers was determined and compared to the achiral synthetic auxin indole-3-butyric acid and to the natural auxin indole-3-acetic acid.

Electrochemistry And Spectroscopy Of Sulfate And Thiosulfate Complexes Of Iron Porphyrins, Philip Walter Crawford, Michael D. Ryan

Chemistry Faculty Research and Publications

The electrochemical and spectroscopic properties of the complex formed by the addition of thiosulfate to ferric porphyrins were examined. The NMR spectrum of the thiosulfate–ferric porphyrin complex was consistent with a high-spin ferric complex, while the EPR spectrum at liquid nitrogen temperatures indicated that the complex under these conditions was low-spin. Such behavior has been previously observed for other ferric porphyrin complexes. The visible spectra were characterized by a shift in the Soret band to higher energies, with smaller changes in the longer wavelength region. The complex was reasonably stable in DMF, but slowly reduced over several hours to Fe …

Future Directions For Mobile-Agent Research, David Kotz, Robert Gray, Daniela Rus

Computer Science Technical Reports

During a discussion in September 2000 the authors examined the future of research on mobile agents and mobile code. (A mobile agent is a running program that can move from host to host in network at times and to places of its own choosing.) In this paper we summarize and reflect on that discussion. It became clear that the field should shift its emphasis toward mobile code, in all its forms, rather than to continue its narrow focus on mobile agents. Furthermore, we encourage the development of modular components, so that application designers may take advantage of code mobility without …
