The Hydraulic Spline: Comparisons Of Existing Surface Modeling Techniques And Development Of A Spline-Based Approach For Hydrographic And Topographic Surface Modeling, Maik Flanagin

LSU New Orleans Theses and Dissertations

Creation of accurate and coherent surface models is vital to the effective planning and construction of flood control and hurricane protection projects. Typically, topographic surface models are synthesized from Delaunay triangulations or interpolated raster grids. Although these techniques are adequate in most general situations, they do not effectively address the specific case where topographic data is available only as cross-section and profile centerline data, such as the elevation sampling produced by traditional hydrographic surveys. The hydraulic spline algorithm was developed to generate irregular two-dimensional channel grids from hydrographic cross-sections at any desired resolution. Hydraulic spline output grids can be easily …

Disaster Response System, Shiquan Fu

LSU New Orleans Theses and Dissertations

With integration of geospatial information system into a conventional information system a basic disaster response information system is implemented. The result is a report on various useful technologies and software engineering methodologies that could be utilized to implement a preliminary system, which in turn clarifies many uncertainties and surprises that are typical of many such systems. The foundations of my project include the Unified Process of software development, the relational data models, the decision tree technique, class design principles such as the MVC pattern.

Current Public Relations Status In China., Fang Meng

Electronic Theses and Dissertations

This study is to explore the status of public relations in China. It examines if J. Grunig and Hunt's (1994) four models of public relations-press agentry, public information, two-way asymmetrical, and two-way symmetrical-are practiced by Chinese public relations practitioners and if there are additional patterns of practicing public relations in China. It is a qualitative study. Long interviews with 10 participants were conducted to learn about the phenomenon of public relations in China. The interviews were based on one-to-one chat via the Microsoft Messenger software online. The data were collected using open-end questions that allowed the participants to provide in-depth …

Excess Noise In The Superconducting Transition Of Tin Films, Hengsong Zhang

Open Access Dissertations

The I-V characteristics of Tin films in the superconducting transition have been measured when ac current was applied. The experimental results suggest that the electrical response in ac is not satisfied with the I-V equation in dc. A new equation was suggested to describe the vortex motion and the vortex pair separation in the two dimensional superconducting transition with ac current, which is satisfied with our experimental results. The excess noises of Tin films in the superconducting transition have been found to depend strongly on the temperature and ac current. An empirical expression of voltage noise density in term of …

Human Activity Recognition And Pathological Gait Pattern Identification, Feng Niu

Open Access Dissertations

Human activity analysis has attracted great interest from computer vision researchers due to its promising applications in many areas such as automated visual surveillance, computer-human interactions, and motion-based identification and diagnosis. This dissertation presents work in two areas: general human activity recognition from video, and human activity analysis for the purpose of identifying pathological gait from both 3D captured data and from video. Even though the research in human activity recognition has been going on for many years, still there are many issues that need more research. This includes the effective representation and modeling of human activities and the segmentation …

2007 Fall Engr333/Biol354 Project Final Report, 2007 Fall Engr333, 2007 Fall Biol354

ENGR 333

The students of Calvin College’s Engineering 333 and Biology 354 classes were given the task of determining “What would it take to make Calvin College Carbon Neutral?” At first glance, it would not appear that classes on Advanced Thermal System Design and Investigations in Plant Ecology would have much in common. However, the biology and engineering students comprising these classes banded together to tackle the problem. Coming to a satisfactory conclusion would require:

• Creating an inventory of Green House Gas (GHG) emissions and sequestration potential
• Coming up with detailed solutions to achieve Carbon Neutrality
• Working out a practical schedule to …

We have searched for exclusive γγ production in proton-antiproton collisions at s=1.96TeV, using 532pb-1 of integrated luminosity taken by the run II Collider Detector at Fermilab. The event signature requires two electromagnetic showers, each with transverse energy ET>5GeV and pseudorapidity |η|<1.0, with no other particles detected in the event. Three candidate events are observed. We discuss the consistency of the three events with γγ, π0π0, or ηη production. The probability that other processes fluctuate to 3 events is 1.7×10-4. An upper limit on the cross section of pp̄→p+γγ+p̄ production is set at 410 fb with 95% confidence level. © 2007 The American Physical Society.

Specialized Accreditation In Collegiate Aviation: An Analysis Of The Perceived Value Of Specialized Accreditation By The Aviation Accreditation Board International, Charles Daniel Prather

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The Council on Aviation Accreditation (CAA) was established in 1988 in response to the need for formal, specialized accreditation of aviation academic programs. The first aviation programs were accredited by the CAA in 1992, and as of November 2007, the newly renamed Aviation Accreditation Board International (AABI) recognized a total 78 accredited programs at 26 institutions worldwide. Although the number of aviation academic programs accredited by the AABI has steadily grown, there are currently only 26 percent of UAA member institutions with AABI accredited programs.

In an effort to understand the current status of specialized accreditation in collegiate aviation and …

N-Glycan Modification In Aspergillus Species, Elke Kainz, Andreas Gallmetzer, Christian Hatzl, Juergen H. Nett, Huijuan Li, Thorsten Schinko, Robert Pachlinger, Harald Berger, Yazmid Reyes-Dominguez, Andreas Bernreiter, Tillmann Gerngross, Stefan Wildt, Joseph Strauss

Dartmouth Scholarship

The production by filamentous fungi of therapeutic glycoproteins intended for use in mammals is held back by the inherent difference in protein N-glycosylation and by the inability of the fungal cell to modify proteins with mammalian glycosylation structures. Here, we report protein N-glycan engineering in two Aspergillus species. We functionally expressed in the fungal hosts heterologous chimeric fusion proteins containing different localization peptides and catalytic domains. . This strategy allowed the isolation of a strain with a functional -1,2-mannosidase producing increased amounts of N-glycans of the Man 5 GlcNAc 2 type. This strain was further engineered by the introduction of …

Publications and Research

In December, 2006, a group of 26 software developers from some of the most widely used life science programming toolkits and phylogenetic software projects converged on Durham, North Carolina, for a Phyloinformatics Hackathon, an intense five-day collaborative software coding event sponsored by the National Evolutionary Synthesis Center (NESCent). The goal was to help researchers to integrate multiple phylogenetic software tools into automated workflows. Participants addressed deficiencies in interoperability between programs by implementing “glue code” and improving support for phylogenetic data exchange standards (particularly NEXUS) across the toolkits. The work was guided by use-cases compiled in advance by both developers and …

Power Reduction Techniques For Memory Elements, Srikanth Katrue

Theses

High performance and computational capability in the current generation processors are made possible by small feature sizes and high device density. To maintain the current drive strength and control the dynamic power in these processors, simultaneous scaling down of supply and threshold voltages is performed. High device density and low threshold voltages result in an increase in the leakage current dissipation. Large on chip caches are integrated onto the current generation processors which are becoming a major contributor to total leakage power. In this work, a novel methodology is proposed to minimize the leakage power and dynamic power. The proposed …

Property Measurements And Evaluation Of Heat Leak, Nathan Race

All Theses

Heat transport in capillary wick structures is an important parameter in loop heat pipe (LHP) design. The purpose of this study was to investigate the conductive heat leak in operating capillary wick structures. The heat leak is the portion of applied heat load conducted through the wick in spite of the convection of working fluid. Four sintered 316 stainless steel wicks were tested for porosity, effective thermal conductivity, pore size, and heat leak. Pore sizes were found to correlate well with the nominal pore size and pores were very narrowly distributed within a size range of approximately 1-10μm. Effective thermal …

Settling For Limited Privacy: How Much Does It Help?, Anna M. Shubina

Dartmouth College Ph.D Dissertations

This thesis explores practical and theoretical aspects of several privacy-providing technologies, including tools for anonymous web-browsing, verifiable electronic voting schemes, and private information retrieval from databases. State-of-art privacy-providing schemes are frequently impractical for implementational reasons or for sheer information-theoretical reasons due to the amount of information that needs to be transmitted. We have been researching the question of whether relaxing the requirements on such schemes, in particular settling for imperfect but sufficient in real-world situations privacy, as opposed to perfect privacy, may be helpful in producing more practical or more efficient schemes. This thesis presents three results. The first result …

Subversia: The SubUrban Subversive, Emily Cox

All Theses

The palimpsest is, by definition, 'writing material (as a parchment or tablet) used one or more times after earlier writing has been erased.' It provides a conceptual field for the layering of text, or meaning, over time. This text may be built up by successive authors and can be altered by additions and erasures. Traces of these amendments remain, providing a history of revision of the original text. Additions that comment on and interpret the primary text are called marginalia.
Landscape operates as a palimpsest, with written, rewritten, erased, and revised layers of history. While typically considered ahistoric, the suburban …

Metalloporphyrin Catalyzed Degradation Of Pce: Effects Of Reductants, Buffers And Cosolvent Concentration, Sowmya Suryanarayanan

All Theses

Reductive dechlorination of chlorinated organic contaminants using metalloporphyrins as catalysts may be an effective approach to treat widespread contamination. However, most previous studies have examined water-soluble rather than insoluble metalloporphyrins despite the fact that the latter category makes up the largest fraction found in nature. Recent studies have shown that addition of different cosolvents to water can activate otherwise non-reactive metalloporphyrin catalysts and facilitate the reduction of tetrachloroethylene (PCE), presumably by the mere process of making the otherwise insoluble metalloporphyrins dissolve in solution. Therefore, solubility has been advanced as a key factor in the ability of metalloporphyrins to catalyze organic …

Neochetina Species And Arthropod Communities In Water-Hyacinth Rafts In South Carolina, Benjamin Powell

All Theses

Arthropod communities inhabiting feral water-hyacinth rafts were surveyed monthly in South Carolina's Coastal Plain from March 2005 through February 2006. Special attention was given to the chevroned waterhyacinth weevil [Neochetina bruchi (Hustache)], the mottled waterhyacinth weevil [N. eichhorniae (Warner)] (both Coleoptera: Curculionidae), and the waterhyacinth moth [Niphograpta albiguttalis (Warren)] (Lepidoptera: Crambidae), which were imported into North America to control water-hyacinth. Communities of arthropods are compared among sites, flow regimes (lentic, lotic, and tidal), and months of the year. The arthropod communities in waterhyacinth rafts in South Carolina are more diverse than previously reported. Rafts in each of …
