Improved Properties Of Taox Films Doped With Al And N, Robert B. Van Dover, Lynn Schneemeyer, R. M. Fleming, D. J. Werder

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Simultaneous addition of Al and N to Ta-O thin films is found to significantly improve the dielectric properties of the films. Specifically, substitution of 10-40 at. % Al for Ta along with approx. 2 at. % N for O is found to decrease the density of catastrophic defects in the films, resulting in high and statistically more uniform breakdown voltages. This conclusion is based on evaluation of approx. 750 individual capacitors in each experiment.

Thermal Plasmaspheric Morphology: Effect Of Geomagnetic And Solar Activity, Mark Anthony Reynolds, G. Ganguli, J.A. Fedder, J. Lemaire, R.R. Meier, D.J. Melendez-Alvira

Publications

A multispecies kinetic model of the thermal plasma in the plasmasphere is used to predict the spatial dependence of the hydrogen ion and helium ion density and temperature for different levels of geomagnetic and solar activity. The particular convection electric field model chosen is intended for the time intervals between substorms. The plasma density and temperature in the equatorial plane are found to exhibit a local-time variation that is sensitive to the details of the convection electric field. In particular, the parallel temperature increases with altitude and the perpendicular temperature decreases with altitude, except in the postmidnight sector, features that …

Pattern Matching Techniques And Their Applications To Computational Molecular Biology - A Review, Eric C. Rouchka

All Computer Science and Engineering Research

Pattern matching techniques have been useful in solving many problems associated with computer science, including data compression (Chrochemore and Lecroq, 1996), data encryption (RSA Laboratories, 1993), and computer vision (Grimson and Huttenlocher, 1990). In recent years, developments in molecular biology have led to large scale sequencing of genomic DNA. Since this data is being produced in such rapid fasion, tools to analyze DNA segments are desired. The goal here is to discuss various techniques and tools for solving various pattern matching questions in computational biology, including optimal sequence alignment, multiple sequence alignment, and buidling models to describe sequence families using …

A Rapid Development Of Dependable Applications In Ad Hoc Mobility, Amy L. Murphy

All Computer Science and Engineering Research

Advances in wireless communication and network computing technologies make possible new kinds of applications involving transient interactions among physical components that move across a wide range of spaces, from the confines of a room to the airspace across an ocean, and require no fixed networking infrastructure to communicate with one another. Such components may come together to form ad hoc networks for the purpose of exchanging information or in order to engage in cooperative task-oriented behaviors. Ad hoc networks are assembled, reshaped and taken apart as components move in and out of communication range; all interactions are transient; computations become …

Implications And Prospects Of Reforming The Market For Secondary Education In The U.S., Steve Kapsos

University Avenue Undergraduate Journal of Economics

The purpose of this paper is to address the complex issue of public school reform. I will focus primarily on the rather generic concept of school choice, which will inevitably be defined and redefined, throughout my analysis. In doing this, I will first examine the structure and composition of the market for education in America. I will then briefly look at some theoretical approaches to educational reform. Lastly, I will examine specific reform proposals that draw on some of the many varying concepts of choice as well as currently enacted projects that have a form of choice as their focus. …

Comparative Analysis Of Max-Planck Gesellschaft And Akademie Der Wissenschften In The Years 1945-1989, Victoria Kats

University Avenue Undergraduate Journal of Economics

The Realm of Science claims to be an autonomous entity, governed by its own rules and institutions. In practice it is difficult to test the extent to which different enveloping political systems affect economics of basic research, as too many cultural and historical differences would distort such a comparison. Unique historical circumstances make East and West Germany the best available ground for setting up an experiment with both experimental and control groups within societies and organizations. Testing the influence of socialistic pressure on economic performance of scientific institutions, the analysis of East German Academy of Sciences and West German Max …

University Avenue Undergraduate Journal of Economics

Game theory has had a profound influence on many fields of the social sciences since its rise to prominence more than fifty years ago. This paper provides an overview of the main concepts in game theory and studies four main areas of its application in economic problems – oligopolistic competition, externalities & public goods, market equilibrium and general equilibrium. The conclusion is that game theory has found a natural place in economics and will continue to contribute to it for many years to come.

Gender Differences In The Causes Of Non-Completion Rates Among Oregon Apprentices: A Case Study Of The Metro Electrical Jtpc, Portland, Oregon, Kerstin Rock

University Avenue Undergraduate Journal of Economics

This paper will address the question of why women drop out of apprenticeship programs at a higher frequency than men. I will examine if there are in fact substantial differences in human capital and social characteristics between female and male apprentices and whether the influence of these characteristics on the probability of finishing depends on the sex of the apprentice. I hypothesize that the reasons apprentices quit prematurely will differ significantly between sexes, especially in reference to educational background, experience, and family situation.

Studies On The Amylolytic Breakdown Of Damaged Starch In Cereal And Non-Cereal Flours, Karen Bailey

Masters

The term starch damage refers to a number of changes to the starch granule structure, which are detectable by different analytical techniques. Damaged starch is the substrate for amylases, which in turn provides carbohydrates that are used in the production of certain foods and food ingredients; as a result, therefore, determination of levels in flours is a procedure carried out routinely by many manufacturers of starch based products. Enzymatic assay methods emulate the susceptibility of damaged starch granules to enzymatic attack. The first aim of this study was to evaluate enzymatic methods(1,2) to determine damaged starch in wheat flours and …

Use Of Excel To Obtain Voltammetric Information On Microelectrodes, Enda Howard, John Cassidy

Articles

The use of curve fitting for the analysis and interpretation of voltammetric data obtained while working with micro electrodes is discussed as a useful exercise for introducing students to the principle of problem solving using least-squares curve-fitting techniques. The advantages associated with this approach to data processing over the approach where the limiting current (i L) alone is used are discussed and its limitations are highlighted. This technique was applied to the determination of unknown concentrations of ferrocyanide and the most satisfactory recovery of concentrations was found when both the va1ues of the formal potential (EO') and concentration ( C) …

A Process For Appraising Commerical Usability Evaluation Methods., Ronan Fitzpatrick, Alan Dix

Conference papers

Recent international quality standards and European Community legislation have identified new software quality factors. These new factors include suitability, installability and adaptability. Other quality factors need to be reviewed in the light of these developments. This has impacted on established commercial usability evaluation methods to the extent that it is appropriate to ask if these evaluation methods comply with the new standards and legislation. In order to answer this question the commercial evaluation methods need to be appraised (meta-evaluation) using a suitable method appraisal process. This paper describes such an appraisal process which specifically addresses the many considerations raised by …

Algorithms For Scheduling Projects With Generalized Precedence Relations, Bert De Reyck, Erik Demeulemeester, Willy Herroelen

Research Collection Lee Kong Chian School Of Business

The problem of scheduling projects under various types of resource constraints constitutes an important and challenging problem which has received increasing attention during the past several years. The bulk of the models and procedures designed for coping with these problem types aim at scheduling project activities to minimize the project duration subject to constant availability constraints on the required set of resources and precedence constraints that indicate that activities can only be started when all of their predecessors have already been finished. However, real-life project scheduling applications often involve more complicated types of precedence relations such as arbitrary minimal and …

A Classification Scheme For Project Scheduling Problems, Willy Herroelen, Erik Demeulemeester, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

The basic concern of scheduling is commonly described as the allocation of limited resources to tasks over time (Lawler et al. 1993, Pinedo 1995). The resources and tasks may take many forms. In project scheduling the tasks refer to the activities belonging to one or more projects. The execution of project activities may require the use of different types of resources (money, crews, equipment, …). The scheduling objectives may also take many forms (minimizing project duration, minimizing project costs, maximizing project revenues, optimizing due date performance,…). The result is a wide and steadily growing variety of problem types which motivates …

“Financial markets are given to excesses and if a boom/bust sequence progresses beyond a certain point, it will never revert to where it came from. Instead of acting like a pendulum, financial markets have recently acted more like a wrecking ball, knocking over one economy after another.” - A testimony before the US House Banking Committee, Sep, 1998. There are three parts to this paper. The first part examines the time series behaviour of the equity indices of ten countries. Using Robinson (1995a)’s modified GPH estimator and Robinson (1994a)’s average periodogram estimator for the differencing parameter, we have detected that …

Effects Of 4-N-Nonylphenol On Life-History Traits And Population Dynamics Of A Polychaete, Flemming T. Hansen, Valery E. Forbes, Thomas L. Forbes

Valery Forbes Publications

A Life-Table-Response Experiment lasting 78 d was performed to investigate the toxic effects of sediment-associated 4-n-nonylphenol (NP) on growth, reproduction, and survivorship of isolated hermaphrodites of the infaunal polychaete Capitella sp. I. Demographic effects were evaluated using both a fully age-classified and a simple twostage model to estimate population growth rates (λ). Decomposition analysis was performed to explore the contributions of each of the affected life-history traits to the effects observed on l. Elasticity analysis was applied to examine the relative sensitivity of λ to changes in each of the different life-history traits under different exposure levels.
