A Coprocessor Design For The Architectural Support Of Non-Numeric Operations, Timothy W. Curry

Retrospective Theses and Dissertations

Computer Science is concerned with the electronic manipulation of information. Continually increasing amounts of computer time are being expended on information that is not numeric. This is represented in part by modem computing requirements such as the block moves associated with context switching and virtual memory management, peripheral device communication, compilers, editors, word processors, databases, and text retrieval. This dissertation examines the traditional support of non-numeric information from a software, firmware, and hardware perspective and presents a coprocessor design to improve the performance of a set of non-numeric operations. Simple micro-coding of operations can provide a degree of performance improvement …

Hardware Algorithms For Data Compression, N. Ranganathan

Retrospective Theses and Dissertations

Data compression is the reduction of redundancy m data representation in order to decrease storage and communication costs. Data compression techniques have been used in practice primarily through software implementations which fail to meet the speed and performance requirements of current and future systems. This Ph.D. dissertation presents a set of hardware algorithms for compression and decompression techniques and the results of detailed simulations performed to quantify the effects of incorporating such hardware in various architectural environments. A new pipelined algorithm for data compression applicable to static binary encoding schemes is presented. A fast hardware algorithm for decompression that uses …

This was accomplished by evaluating the two finalists of those vendors who answered the district's Request for Proposal (RFP). Of the five vendors who responded to the RFP. CLSI and SIRSI were selected as the systems most likely to meet the needs of the media centers of the school district.

An overview and definition of IOLS was first discussed. This overview then related itself to the needs of the school …

Resource Sharing: A Study Of Florida's Shared-Used Library Collections, Susan Anderson

CCAC Theses and Dissertations

Designed to provide library service for two or more different groups of library users in one library facility, shared-use or joint-use libraries are a unique aspect of library resources sharing. Thirteen examples of shared-use library collections in shared or joint-use library facilities in Florida were examined in this investigation. Special focus was placed on the perceptions of librarians who work in these libraries in order to determine how well the libraries meet the information needs on users and how successful the libraries are in conserving financial resources as a result of combined collections. A design of a special resource collections …

Stratigraphy, Paleontology And Paleobiogeography Of Lower Vertebrates From The Cedar Mountain Formation (Lower Cretaceous), Emery County, Utah, Michael L. Pomes

Master's Theses or Doctor of Nursing Practice

Where present, the basal Buckhorn Member of the Cedar Mountain Formation (Aptian-Albian) separates the overlying main member from the mudrocks of the Tithonian Brushy Basin Member of the Morrison Formation. Without the Buckhorn, the mudrocks of the Cedar Mountain Formation appear to grade into those of the Morrison, so one is apt to call the entire sequence Morrison. Where the Cedar Mountain Formation appears to grade in to the Morrison, use of lower vertebrate teeth can provide an additional means to separate the Morrison from the Cedar Mountain Formation. Lower vertebrate teeth and associated microvertebrate remains (eggshell and bone fragments) …

Automatically Generating Syntax-Directed Editors For Graphical Languages, Farahangiz Arefi

Retrospective Theses and Dissertations

This research is concerned with the automatic generation of syntax-directed editors for graphical programming languages. A specification technique that is used to uniformly define graphical languages along with their syntax-directed editors is developed. The novel aspect of this specification technique, called a general graph transformation system, is that the graphical languages are described by specifying a family of editing operations. In this manner, a language is defined as a dynamic object which, by applying different editing operations, changes from one form to another, each form representing a sentence of the language. In order to demonstrate this process, the language of …

Generating Multiple User Interfaces For Multiple Application Domains, Mahesh Hassomal Dodani

Retrospective Theses and Dissertations

This Ph.D. dissertation presents a classification scheme for User Interface Development Environments (UIDEs) based on the multiplicity of user interfaces and application domains that can be supported. The SISD, SIMD and MISD [S= Single, I= user Interface(s), M= Multiple, D= application Domain(s)] generator classes encompass most of the UIDEs described in the literature. A major goal of this research is to allow any user to develop a personalized interface for any interactive application, that is, the development of an MIMD UIDE.

Fundamental to the development of such a UIDE is the complete separation of the user interface component from the …

On K - Y - Insensitive Donimation, Teresa Haynes Rice

Retrospective Theses and Dissertations

A connected graph G is defined to be k-1-insensitive if the domination number 1(G) is unchanged when an arbitrary set of k edges is removed. The problem has been solved fork= 1. This Ph.D. dissertation focuses on finding extremal k-1-insensitive graphs on p nodes, fork~ 2. A graph is extremal if it has the minimum number of edges. Two subproblems are considered. The first, which has been solved completely, specifies that the same set of nodes dominates each graph obtained from G by removing k edges. The second requires only that the graph G be connected. This is a much …

A Relational Object-Oriented Management System And An Encapsulated Object-Oriented Programming System, Michael L. Nelson

Retrospective Theses and Dissertations

The purpose of the Relational Object-Oriented Management System (ROOMS) is to show that the relational database scheme is a viable approach for storing objectoriented data. ROOMS is designed so that it can be implemented in any object-oriented language with appropriate I/O commands, or added to any objectoriented database management system that allows userdefined collections of data. Various problems were encountered in developing ROOMS. While these problems have been solved, the best solution is to use the Encapsulated Object-Oriented Programming System (EOOPS) . EOOPS is based upon an inheritance scheme which preserves encapsulation. This encapsulated approach avoids the problems associated with …

Some Optimally Adaptive Parallel Graph Algorithms On Erew Pram Model, Sajal K. Das

Retrospective Theses and Dissertations

The study of graph algorithms is an important area of research in computer science, since graphs offer useful tools to model many real-world situations. The commercial availability of parallel computers have led to the development of efficient parallel graph algorithms.

Using an exclusive-read and exclusive-write (EREW) parallel random access machine (PRAM) as the computation model with a fixed number of processors, we design and analyze parallel algorithms for seven undirected graph problems, such as, connected components, spanning forest, fundamental cycle set, bridges, bipartiteness, assignment problems, and approximate vertex coloring. For all but the last two problems, the input data structure …

Vibrational Frequencies And Intensities Of H‐Bonded And Li‐Bonded Complexes. H3n⋅⋅Hcl And H3n⋅⋅Licl, M. M. Szczesniak, I. J. Kurnig, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

The geometries, energetics, and vibrational spectra are calculated for the two complexes at the SCF and correlated MP2 levels using the 6‐31G∗∗ basis set, augmented by a second set of d functions on Cl. While correlation represents an important factor in the binding of H₃ N⋅⋅HCl, it contributes little to the stronger Li bond. Unlike the HCl stretch ν_s which decreases substantially in frequency and is greatly intensified in H₃ N⋅⋅HCl, the frequency of the LiCl stretch undergoes an increase and little change is noted in its intensity, conforming to prior spectral measurements. The intensities of the …

Preliminary Groundwater And Salinity Investigations In The Eastern Wheatbelt 2. Merredin Catchment, Richard J. George Dr, P W C Frantom

Resource management technical reports

Saline groundwater occurs within twelve metres of the surface throughout the valley of the Merredin catchment. Saline groundwater occurs within deep sediments deposited in the valley and deeply-weathered bedrock materials. Rapid groundwater recharge appears to be taking place in sandy-textured soils high in the landscape and directly into the Cainozoic sediments in the valley floor. Water-tables are rising at approximately ten centimetres each year in the upper catchment area.

Continuation Of A Deep Borehole Stress Measurement Profile Near The San Andreas Fault 1. Hydraulic Fracturing Stress Measurements At Hi Vista, Mojave Desert, California, Stephen H. Hickman, Mark D. Zoback, John H. Healy

United States Geological Survey: Staff Publications

Hydraulic fracturing stress measurements were made in a 592-m-deep well at Hi Vista, California, 32 km from the San Andreas fault in the western Mojave Desert. The relative magnitudes of the horizontal principal stresses and the calculated overburden stress indicate that the stress regime at this site is transitional between thrust faulting and strike-slip faulting. The azimuths of the induced hydraulic fractureast Hi Vista exhibit considerable scatter, and the indicated direction of them aximum horizontal principal stress ranges from north-northeast to northwest. The measured magnitudes of the horizontal principal stresses and the horizontal deviatoric stress in this well are less …

Evaluation Of Possible Reproductively Mediated Character Displacement In The Crayfishes, Orconectes Rusticus And O. Sanbornii, Mark J. Butler Iv

Biological Sciences Faculty Publications

Orconectes rusticus is replacing several species of crayfishes in north-central and northeastern North America, including O. sanbornii in Ohio. Recent evidence suggests that the species replacements may be driven by asymmetrical reproductive success favoring O. rusticus. Nonetheless, some sympatric associations appear locally persistent. Because crayfish demonstrate size assortative mating and there is a disparity in the sizes of the species, further divergence in the sizes of the species in sympatry could enhance reproductive isolation, ultimately providing a mechanism for character displacement. To test this hypothesis the size differentials between crayfish collected from allopatric and sympatric populations in east-central Ohio …

The purpose of this study was to determine the geochemical fingerprint for the Sentinel Butte ash/bentonite, and use this fingerprint to assess the correlation value of this and other terrestrial bentonites. Mapping enlarged the known geographic distribution of this unit and provided an insight into its diagenetic history.

Samples from thirty randomly chosen sites and fifteen grab sites were used to evaluate the …

Academically-Sponsored Coastal Research Vessels In The New England Region: An Assessment Of Current Management And Implications For The Future, Brendan B. Mcavoy

Marine Affairs Theses and Major Papers

In New England an informal communications network exists between coastal research vessel operating institutions. Vessel scheduling and operational support has been identified as adequate for the current amount of research being conducted within the region. However, societal shift towards coastal regions is prompting an increase in attention to research within the coastal zone. Current and pending federal initiatives are responding to this increased research need. This, in turn, is beginning to impose greater demands on coastal vessel sea-time. Therefore, a strengthening of the region's inter-institutional communications network may be warranted for the future in order to better coordinate coastal research …

The Impact Of Public Policy On Portland's Waterfront, John G. Ferland

Marine Affairs Theses and Major Papers

In May, 1987, Portland voters approved by a 2-to-1 margin a referendum preventing non-marine development along its waterfront for at least five years. It has become clear that the vote was not just a Portland waterfront issue. To many, the vote was a statement of no confidence in growth regulations and unhappiness with the pace of development throughout the Greater Portland region. The vote illustrated that there is no consensus on Greater Portland's future. For Portland's waterfront, a lack of consensus is nothing new. Portland has debated waterfront policy in fits and starts for most of the 20th century. As …

The Energy-Dependence Of Polarization Observables In The ²H(D,Γ)⁴He Reaction, H. R. Weller, R. M. Whitton, J. Langenbrunner, Evans Hayward, W. R. Dodge, S. Kuhn, D. R. Tilley

Physics Faculty Publications

Measurements of the tensor and vector analyzing powers, A_yy(130°) and A_y(130°), have been obtained for the ²H(d,γ )⁴He reaction for energies ranging from E_d(lab) = 0.3 MeV to E_d(lab) = _{50 MeV}. The A_yy(130°) data are sensitive to the D-state present in the ground state of ⁴He and are observed to have their maximum value near E_d = 30 MeV. The vector analyzing power data show a maximum near E_d = 3 MeV. The data are compared to the results of a microscopic …

Dynamics Of Antimatter-Atom Collisions, Ronald E. Olson, Timothy James Gay

Physics Faculty Research & Creative Works

Classical-trajectory Monte Carlo calculations have been used to study ionizing collisions between charged particles (p,p»,e+,e-) and He atoms at an incident velocity of 2.83 a.u. While differences in the total single-ionization cross sections for these projectiles are small, our calculations reveal large effects at all angles in the ionized electron spectra and provide qualitative evidence for a Barkas effect in p and p» collisions. Experimental data agree well with our fully classical calculations, including cross sections involving ejected electrons of long wavelength. © 1988 The American Physical Society.

A Study Of Vapor Phase Self-Initiated Thermal Polymerization Of Styrene With An Expansion Chamber, John L. Schmitt

Physics Faculty Research & Creative Works

Studies of the self-initiated polymerization of styrene have been performed in the uniform environment of an expansion cloud chamber, using nucleation of liquid monomer drops for detection. These studies are the first of this kind in an expansion chamber and, although preliminary and designed to explore feasibility, have yielded many interesting results. The occurrence of the self-initiated nonterminated gas phase processes, previously observed in a diffusion cloud chamber, has now been confirmed in an expansion chamber. At 15 °C the initiation rate is measured to be 2 to 6 radicals cm-3 s-1 and the propagation constant is approximately 6X10-21 cm3 …

Projectile-Charge Dependence Of Ejected-Electron Spectra, V. D. Irby, Timothy James Gay, Jimmie Garwin Edwards, Edward Boyd Hale, M. L. Mckenzie, Ronald E. Olson

Physics Faculty Research & Creative Works

We have studied H⁺+He and He⁺+3+He ionizing collisions at intermediate energies (60 to 120 keV/amu) and have observed a significant shift in the velocity position of the maxima in forward-ejected electron spectra when changing projectiles from protons to particles. In ionizing collisions, a large portion of the ejected electrons are stranded near the transitory equiforce, or saddle point, position between the target ion and receding projectile. The shift in the electron spectra maxima to smaller velocities, due to changing projectiles from protons to particles, is consistent with the shift in the saddle-point velocity when the projectile …

No Antitwins In Minimal Imperfect Graphs, Stephan Olariu

Computer Science Faculty Publications

It is customary to call vertices x and y twins if every vertex distinct from x and y is adjacent either to both of them or to neither of them. By analogy, we shall call vertices x and yantitwins if every vertex distinct from x and y is adjacent to precisely one of them. Lovász proved that no minimal imperfect graph has twins. The purpose of this note is to prove the analogous statement for antitwins.

Ion-Association Complexes Of Thallium And Mercury With Rhodamine 6g In Aqueous Solution, Nasrein El-Masri

University of the Pacific Theses and Dissertations

The present study involves the determination of traces of thallium and mercury in aqueous solution by forming ion-association complexes of these metals with rhodamine 6G (R6G) in the presence of iodide. Thallium(lll) and mercury(Il) are able to quench the fluorescence of R6G in the presence of iodide by forming ion—association complexes, and the degree of quenching correlates with the thallium(III) or mercury(II) concentrations . By using this method, the minimum amount of thallium- (III) that can be determined in aqueous solutions is approximately 4.00 X 10-6m, while the minimum amount of mercury(II) is approximately 3.00 X 10-6m. Thallium(I) cannot be …
