Fluctuation History Of Great Salt Lake, Utah, During The Last 13,000 Years, United States, National Aeronautics And Space Administration

Water

Great Salt Lake level fluctuations from 13,000 yr B.P. to the present were interpreted by examination of shoreline geomorphic features, shoreline deposits, archeologic sites, isotopic data, and palynologic data.

After the conclusion of the Bonneville paleolake cycle, between 13,000 and 12,000 yr B.P. the lake regressed to levels low enough to deposit a littoral oxidized red bed stratum and a pelagic Glauber's salt layer. A late Pleistocene lake cycle occurred between 12,000 and 10,000 yr B.P. depositing several beaches, the highest reaching an altitude of about 4250 ft (1295.3 m). The lake regressed after 10,000 yr B.P., only to rise …

Analysis Of A Parallel Mergesort, Per Brinch Hansen

Electrical Engineering and Computer Science - Technical Reports

The paper describes a performance model of a fine-grained, parallel mergesort which sorts N elements in 0(N) time using 0(logN) processors. The model predicts both the communication time involved in merging the elements and the decomposition time required to activate and terminate the binary tree of processes. The parallel algorithm is written in Joyce and runs on an Encore Multimax.

Nonnegative Solutions For A Class Of Radially Symmetric Nonpositone Problems, Alfonso Castro, Ratnasingham Shivaji

All HMC Faculty Publications and Research

We consider the existence of radially symmetric non-negative solutions for the boundary value problem

\begin{displaymath}\begin{array}{*{20}{c}} { - \Delta u(x) = \lambda f(u(x))\qua... ...\\ {u(x) = 0\quad \left\Vert x \right\Vert = 1} \\ \end{array} \end{displaymath}

where $ \lambda > 0,f(0) < 0$ (non-positone), $ f' \geq 0$ and $ f$ is superlinear. We establish existence of non-negative solutions for $ \lambda $ small which extends some work of our previous paper on non-positone problems, where we considered the case $ N = 1$. Our work also proves a recent conjecture by Joel Smoller and Arthur Wasserman.

The Remipedia (Crustacea): A Study Of Their Reproduction And Ecology, Jill Yager

Biological Sciences Theses & Dissertations

Remipedes are an unusual group of troglobitic crustaceans that live exclusively in anchialine caves. Since their discovery in 1979, nine species have been described, seven of which are found in caves in the West Indies, one from the Yucatan peninsula of Mexico and one from the Canary Islands. Most of what is known about these animals has come mainly from taxonomic descriptions. Little has been published about their reproductive biology or ecology. The objectives of this dissertation were to investigate the reproductive biology and ecology of the remipedes inhabiting Sagittarius Cave on Grand Bahama Island, Bahamas.

Sagittarius Cave was chosen …

Picoplankton/Phytoplankton Dynamics In Hampton Roads, Virginia, Leslie E. Dorworth

OES Theses and Dissertations

The biomass distribution of the three main size components of the phytoplankton (net, nano, and picoplankton) was examined in the lower Chesapeake Bay. Work was done at two stations during the spring and neap tidal cycles when freshwater flow into the bay was at its seasonal minimum and maximum. Emphasis was placed on how the picoplankton ( < 2.0 μm, > 0.2 μm) reacted during the sampling period.

Picoplankton made up approximately 13% of the total biomass, during the observed time period, at the more oceanic station. The picoplankton fraction contributed up to 16% of the total biomass at the estuarine station. From this …

Parity Retransmission Hybrid Arq Using Rate 1/2 Convolutional Codes On A Nonstationary Channel, L. R. Lugand, D. J. Costello, Jr., Robert H. Deng

Research Collection School Of Computing and Information Systems

A parity retransmission hybrid automatic repeat request (ARQ) scheme is proposed which uses rate 1/2 convolutional codes and Viterbi decoding. A protocol is described which is capable of achieving higher throughputs than previously proposed parity retransmission schemes. The performance analysis is based on a two-state Markov model of a nonstationary channel. This model constitutes a first approximation to a nonstationary channel. The two-state channel model is used to analyze the throughput and undetected error probability of the protocol presented when the receiver has both an infinite and a finite buffer size. It is shown that the throughput improves as the …

Fault Tolerance In A Very Large Database System: A Strawman Analysis, Amit P. Sheth

Kno.e.sis Publications

A simple model is used to study the effect of fault-tolerance techniques and system design on system availability. A generic multiprocessor architecture is used that can be configured in different ways to study the effect of system architectures. Important parameters studied are different system architectures and hardware fault-tolerance techniques, mean time to failure of basic components, database size and distribution, interconnect capacity, etc. Quantitative analysis compares the relative effect of different parameter values. Results show that the effect of different parameter values on system availability can be very significant. System architecture, use of hardware fault tolerance (particularly mirroring), and data …

Determining Pesticide And Nitrate Levels In Spring Water In Northwest Arkansas, T. L. Lavy, B. A. Dehart, John D. Mattice

Arkansas Water Resources Center Technical Reports

Occurrences of pesticides in our nations ground water are on the rise. As states become aware of this problem and begin monitoring programs, incidence of contamination will probably increase. Since the problem of pesticides in groundwater is relatively new, little research has centered on the fate of pesticides after they reach the groundwater environment. In Northwest Arkansas efforts to monitor groundwater for pesticides have been small. Twenty-five springs in Northwest Arkansas were sampled in the fall of 1988, and spring of 1989. Analysis for atrazine, alachlor, metolachlor, diuron, and simazine in spring water was preformed using gas liquid chromatography and …

Analysis, Design And Implementation Of A Pilot Relational Database For Groundwater In The State Of Arkansas, Ray Hashemi-Nassab

Arkansas Water Resources Center Technical Reports

There are several agencies within the state of Arkansas dealing with underground water. Each agency has its own database that acts as an isolated depository of data. Practically, the communication among these databases is zero, not because there is no need for it, but because the communication is very difficult if not impossible. Data redundancy, inconsistency, and lack of integrity is overwhelming. In this study we have addressed the problem of lack of unity among the databases belonging to different agencies. Also, as an alternative we have developed a relational database. In this database the data was normalized to 4NF. …

An Expert System For Managing An Activated Sludge Wastewater Treatment Plant, Sandra C. Parker, David G. Parker

Arkansas Water Resources Center Technical Reports

A diagnostic expert system for an activated sludge wastewater treatment plant has been designed to link with a relational database management system for obtaining operational parameter values that are used by the program to diagnose operational problems that may occur in the process. The problems that are dealt with by the system are bulking sludge, floating sludge, defloculation, ashing, solids washout, foaming problems, high soluble effluent BOD and problems in the aeration system. The link between the expert system and the database is accomplished via programming that is initiated by the expert system program. The operator of the system is …

Simulation Of The Fate Of Nitrogen From The Disposal Of Poultry Litter, H. D. Scott

Arkansas Water Resources Center Technical Reports

A PC/AT computer model was developed to simulate the transport of water, nitrate and ammonia in the soil profile after an application of poultry litter to pasture. The model was written using FORTRAN 77 compiler and can be used on any IBM type compatible computer with a math coprocessor. Poultry litter has been shown to be a potential source of plant nutrients, but mismanagement can result in nitrate pollution of the surface and groundwater. The model is composed of a main program, 11 subroutines and three subprograms. An example was shown of the flexibility and dynamic nature of the computer …

Anthropometric Parameters In Public School Students And Seventh-Day Adventist Vegetarian And Meat-Eating Students, Joan Sabaté-Casellas

Loma Linda University Electronic Theses, Dissertations & Projects

Concerns have been expressed for the ability of some vegetarian diets to support normal growth of children. Animal protein or meat intake showed a positive relationship to attained height in children from developing countries. In this study, the relationship between meat intake/vegetarian status and physical growth was investigated in children living in California.

Height and weight were collected on 2,272 Caucasian children aged 6-18 years attending Seventh-day Adventist (SDA) or public schools who participated in a two year longitudinal study. Age-, sex-, and school-specific mean heights and weights were at or above the national reference values. Sex-specific, age-adjusted regression analysis …

Misfit Between Motivational Style And Type Of Job Demand As A Factor In Developing Occupational Stress, Arlene Gray Blix

Loma Linda University Electronic Theses, Dissertations & Projects

Occupational stress is costly in terms of human suffering and impaired organizational effectiveness. Occupational stress involves the interface between the individual worker and the work environment. The purpose of the study was to analyze the fit between motivational style and the type of job demands as a contributing factor in developing occupational stress symptoms. A literature review of occupational stress models was conducted. The six models compared and contrasted included the Person-Environment fit model (French, Rodgers, & Cobb, 1974), Integrative Transactional Model (Schuler, 1982), Organizational Stress Models (Ivancevich & Matteson, 1987; Parker & DeCotiis, 1983), Facet Analysis Model (Beehr & …

Facial Typing Methods : A Comparative Study, James A. Grabow

Loma Linda University Electronic Theses, Dissertations & Projects

Facial typing methods are used to determine to which of three basic facial pattern categories an individual patient belongs. These three categories are mesofacial, brachyfacial, and dolichofacial. It is important to establish the correct facial type because the reaction to treatment mechanics and the stability of the denture is dependent upon the analysis of the facial patterns. The purpose of this paper was to show a comparative study of facial typing classification methods used on 100 patients (47 boys and 53 girls). The eight different methods used were as follows: Bioprogressive, Ricketts LLU1, LLU2, QuickCeph™, Jarabak, Facial-Mandibular Index, and Steiner. …

Program Analysis Tool For Extensive Reverse Software Engineering : A Tool To Understand The Software (Patern), Bubulal R. Rawal

Conceptually, PATERN provides systems analysts/programmers with a powerful tool independent of programming language, operating system, and programmer style of coding for documenting existing software. PATERN has been tested with C code in the UNIX environment. This thesis also describes the interface between PATERN and two subsystems that interact with PATERN: relational databases and data flow diagram generators. The implementation of these interfaces was investigated using Informix and another software tool, Directed Acyclic Graphs (DAG) for generating hierarchical structure charts and flow …

Towards A Bound For The Compression Of The Lzw Algorithm, Anoop Kumar Srivastava, Shinu Gupta

Theses

The LZW algorithm is a well known efficient adaptive compression algorithm. It is based on constructing a dictionary containing character strings from the text. A number of researchers have attempted to add variations to the original algorithm to achieve higher compression values. In this thesis we attempt to find a bound for the LZW approach. That is, we build a dictionary which gives maximum compression and satisfies prefix property of LZW algorithm.

In order to build such an optimum dictionary, the dynamic programming technique is applied. The final dictionary selected consists of entries which give maximum overall compression and also …

Substituent Effects On Strained Rings. Part A ; The Kinetics Of Hydrolysis Of A Quinuclidone Using Ftir. Part B, Yeu-Yi Chiu

Theses

PART A: The energies of a series of monosubstitued propane, cyclopropane and cyclopropene compounds were calculated using ab initio molecular orbital calculations optimized at the 3-21G level using Gaussian 82 and Gaussian 86 programs. The effects of substituents on stabilization energies and geometries are rationalized with respect to the parent molecules. The result is presented which indicated that for substituted cyclopropyl and cyclopropenyl compounds, most of the substituents induce stabilization except the —NC substituent group is destabilizing in cyclopropyl and cyclopropenyl systems. Indications of relative electrostatic and resonance effects are also analyzed. A linear free energy relationship has been exam-ined …
