Hardware Software Synthesis Of A H.264 / Avc Baseline Profile Decoder, Stephen P. Joralemon

Theses

The latest video compression standard is a joint effort between ITU and MPEG known as H.264/AVC. As with any video compression standard the H.264/AVC uses computationally intensive algorithms to maximize performance. During decompression these algorithms must be applied in real-time, processing 30 frames a second. This can be done in software, specialized hardware, or a combination of the two. Software solutions allow for maximum portability and ease of design, but General Purpose Processors (GPP) can not take full advantage of the parallelizable algorithms that the H.264 decoder is based upon. Specialized hardware solutions, on the other hand, allow concurrent data …

Denial Of Service Attack Techniques: Analysis, Implementation And Comparison, Khaled M. Elleithy, Drazen Blagovic, Wang K. Cheng, Paul Sideleau

School of Computer Science & Engineering Faculty Publications

A denial of service attack (DOS) is any type of attack on a networking structure to disable a server from servicing its clients. Attacks range from sending millions of requests to a server in an attempt to slow it down, flooding a server with large packets of invalid data, to sending requests with an invalid or spoofed IP address. In this paper we show the implementation and analysis of three main types of attack: Ping of Death, TCP SYN Flood, and Distributed DOS. The Ping of Death attack will be simulated against a Microsoft Windows 95 computer. The TCP SYN …

Calculus-Based Physics Modules, Authors And Anecdotes, Robert Fuller, David Winch

Personalized System of Instruction (PSI), or Keller Plan, Materials

Fifteen experienced Keller Plan physicists gathered on the University of Colorado Boulder campus in the summer of 1975 to create a complete Keller Plan course for calculus-based physics. After three weeks, the original drafts, almost 1100 pages, were completed and the authors scattered to their places of employment. This poster tells stories about these module authors since 1975 and how the calculus-based physics modules were used.

Personalized System of Instruction (PSI), or Keller Plan, Materials

The Personalized System of Instruction (PSI), or Keller Plan – Thirty Years Later

In the early 1970s a mastery-oriented, self-paced style of instruction, called the Personalized System of Instruction, or Keller Plan, came into physics courses. For a few years the Keller Plan flourished and reached an apex in physics with the publication of a complete set of Keller Plan materials for the calculus-based physics course in 1975. By 1980 it had all but disappeared from physics courses. This presentation will discuss the features of the Keller Plan, the explanations of why it disappeared and what are some attributes of …

Transient Analysis Of A Porous Electrode, Sheba Devan, Venkat R. Subramanian, Ralph E. White

Faculty Publications

An analytical expression is presented for the voltage response including the transient voltage for a simple (i.e., no concentration gradients) porous electrode model subject to a sinusoidal input current density. The transient voltage response as a function of the frequency, exchange current density, and double layer capacitance is studied independent of the periodic (steady state) voltage response. The change in the voltage response in the transient region is compared to that of the periodic voltage response with respect to the parameters. The physical properties of the porous electrode can be estimated using the voltage response in the transient …

Cubic Spline Regression For The Open-Circuit Potential Curves Of A Lithium-Ion Battery, Qingzhi Guo, Ralph E. White

Faculty Publications

A cubic spline regression model was used to fit the experimental open-circuit potential (OCP) curves of two intercalation electrodes of a lithium-ion battery. All the details of an OCP curve were accurately predicted by the resulting model. The number of regression intervals used to fit an OCP curve was determined in a way such that in each regression interval the OCP exhibits a profile predictable by a third-order polynomial. The locations of the data points used to separate regression intervals were optimized. Compared to a polynomial model with the same number of fitting parameters, the cubic spline regression model is …

A Mathematical Model For A Lithium-Ion Battery/Electrochemical Capacitor Hybrid System, Godfrey Sikha, Ralph E. White, Branko N. Popov

Faculty Publications

A one-dimensional model for predicting the performance of a battery/electrochemical capacitor-hybrid system has been developed. Simulation results are presented for a LiCoO₂|LiPF₆ ethylene carbonate/dimethyl carbonate|carbon battery system and a Maxwell PC 10F carbon double-layer electrochemical capacitor. The current shared between the battery and the electrochemical capacitor at very short times depends on the ohmic resistances of the battery and the capacitor. As the discharge proceeds, the operating conditions such as frequency, duty ratio, and peak pulse discharge current control the current shared among parallel circuits. These parameters also determine the extent of the run time increase of …

Patterns Of Plant Species Diversity In Remnant And Restored Tallgrass Prairies, H. Wayne Polley, Justin D. Derner, Brian J. Wilsey

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

To restore diversity of native vegetation, we must understand factors responsible for diversity in targeted communities. These factors operate at different spatial scales and may affect the number and relative abundances of species differently. We measured diversity of plant species and functional groups of species in replicated plots within paired restored and remnant (relic) tallgrass prairies at three locations in central Texas, U.S.A.

Stable Isotopes In Obesity Research, Gregory G. Dolnikowski, Julian B. Marsh, Sai Krupa Das, Francine K. Welty

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Obesity is recognized as a major public health problem. Obesity is a multifactorial disease and is often associated with a wide range of comorbidities including hypertension, non-insulin dependent (Type II) diabetes mellitus, and cardiovascular disease, all of which contribute to morbidity and mortality. This review deals with stable isotope mass spectrometric methods and the application of stable isotopes to metabolic studies of obesity. Body composition and total energy expenditure (TEE) can be measured by mass spectrometry using stable isotope labeled water, and the metabolism of protein, lipid, and carbohydrate can be measured using appropriate labeled tracer molecules.

The Influence Of British Culture On The Advance Of Modern Architecture In The United Kingdom, Shannon K. Holt

Honors Program Theses

Through exploring literature, conducting on-site observations and living in London, I have examined these questions with respect to the history of Modem architecture and Britain's respective role in it, the history of Britain and of their urban planning and architectural needs, the introduction of the Modem style and the subsequent backlash, the influence of the Prince of Wales, and the direct influence of the culture itself. I have attempted to analyze both the history, the present, and to speculate on the future of the Modem movement in the United Kingdom.

Creating Breadth In Business Education Through Service-Learning, Paul C. Godfrey, Louise M. Illes, Gregory R. Berry

Faculty Publications

We argue service-learning pedagogy and the associated educational experiences provide a partial solution to the significant problem of narrowness in business education. Servicelearning pedagogy seeks to balance academic rigor with practical relevance, set in a context of civic engagement, which furnishes students with a broader and, we argue, richer, educational experience. We present four specific critiques of business education: (1) the business curriculum focuses on functional and discrete rather than cross-functional and holistic knowledge; (2) coursework emphasizes practical problem-solving “tool kits” rather than deep theoretical knowledge; (3) the underlying paradigm of business education views humanity and human interactions in purely …

Analytical Tools For Studying Phosphorus And Nitrogen Lake Nutrient Dynamics And Their Application To The Field, Ivan Mihajlov

Honors Theses

In order to evaluate the causes and conditions that lead to cyanobacteria blooms in northern temperate lakes, studies of nutrients such as total phosphorus, total nitrogen, phosphate, and nitrate are necessary. Sensitive, environmentally friendly and cost-effective techniques were developed to detect ppb-level nitrates and phosphates in the lake water. Phosphate was analyzed by luminol chemiluminescence, while the quantification of nitrate was performed by capillary electrophoresis (CE) using indirect UV detection, with a background electrolyte consisting of pyromellitic acid, hexamethonium hydroxide and triethanolamine. Sample injection methods for the CE were optimized for the analysis in Belgrade Lakes, Maine. Vertical profiles of …

Investigation Of Iron (Iii) Desferrioxamine B Oxalate Ligand Exchange By Uv-Vis Spectroscopy: The Next Step In Developing A Quantitative Analytical Method For Measuring Bioavailable Iron In Marine Ecosystems, Ken L. Pitter

Honors Theses

To date there are no analytical techniques designed to exclusively measure bioavailable iron in marine environments. The goal of this research is to develop such a technique by isolating the bioavailable iron using the terrestrial siderophore desferrioxamine B (DFB). This project contained many challenging aspects, but the specific goal of this study was to develop a robust analytical technique for quantification of Fe(III)-DFB complexes at nanomolar concentrations. Past work showed that oxalate (Ox) promotes photodissociation of Fe(III)-DFB to Fe(Il), and we are specifically interested in the mechanism of this process. A model was developed using known thermodynamic constants for Fe(III)-DFB …

Photochemical Generation Of 2-Methoxy-2methylpropylidene And Its Rearrangement Pathways, Stanislav Presolski

Honors Theses

2-methoxy-2-methylpropylidene was photochemically generated from a non-nitrogenous precursor, 1a,9b-Dihydro-IH-cyclopropa[1]phenanthrene-l-etbane 2-methoxy-2-methyl, available in two steps from phenanthrene. Two competing rearrangement pathways were observed for the p-methoxy carbene, 1,2-methyl shift and C-H insertion, which had varying weights depending on the solvent used. Nevertheless, the C-H insertion was always predominant, contrary to the current understanding of B-substituted carbenes, which apparently needs revision. An attempt was also made to measure by LFP the rate constant of rearrangement and lifetime of the stabilized l-chloro-2-methoxy-2-metbylpropylidene.

Belief In A Just World, School Stress And Academic Success, Elizabeth A. Hepworth

Theses

Belief in a just world, a construct first introduced by Lerner (1978), has been the topic of psychological research for the past forty years (Lerner, 1965; Rubin & Peplau, 1973; Tomaka & Blascovich, 1994; Dalbert, 1999; Hafer, 2000; Furnham, 2003). Much of the research conducted on the belief in a just world focused on its cognitive use as a protective mechanism. For example, Belief in a Just World (BJW) has been positively correlated with helping behavior (Beirhoff, 2002), commitment to long range goals (Hafer, 2000), positive well-being (Dalbert, 2000), and negatively associated with stress (Takoma & Blascovich, 1994). In the …

Khawla Hamad Mohd Al-Areef Al-Dhaheri

Abstract

Various patho-groups of Escherichia coli strains are important causes of diarrheal diseases worldwide. Among these strains Shiga toxin producing isolates are particularly important. They are carried by various animals and upon infection, in humans, they may cause serious bloody diarrhea, and in some cases even life threatening sequels as hemolytic uremic syndrome. However, these infections are often under-diagnosed due to the fact that pathogenic strains do not differ from their nonpathogenic counterparts in characters investigated by standard microbiological techniques. Consequently, they can only be …

Effect Of Some Medicinal Plants In U.A.E. On Glucose Homeostasis In Rats, Fatma Khadem Al-Ghaithi

Theses

Diabetes mellitus is one of the most common endocrine diseases in the world that affects almost 6% of the world population. The treatment of diabetes mellitus takes three main forms. First, diet and exercise. Secondly, insulin therapy, and thirdly, using hypoglycaemic agents (suiphonylureas and biguanides). Many of these agents are not very effective in lowering glucose level in diabetic patients and are either too expensive or have undesirable side effects and contraindications. As a result of this, the search for effective drugs for the treatment of diabetes mellitus continues.

Before the introduction of insulin in 1922, the treatment of diabetes …

A Multi-Agent Approach For Solving Optimization Problems Involving Expensive Resources, Hoong Chuin Lau, H. Wang

Research Collection School Of Computing and Information Systems

In this paper, we propose a multi-agent approach for solving a class of optimization problems involving expensive resources, where monolithic local search schemes perform miserably. More specifically, we study the class of bin-packing problems. Under our proposed Fine-Grained Agent System scheme, rational agents work both collaboratively and selfishly based on local search and mimic physics-motivated systems. We apply our approach to a generalization of bin-packing - the Inventory Routing Problem with Time Windows - which is an important logistics problem, and demonstrate the efficiency and effectiveness of our approach.
