Comparative Study Of Stock Trend Prediction Using Time Delay, Recurrent And Probabilistic Neural Networks, Donald C. Wunsch, Emad W. Saad, Danil V. Prokhorov

Electrical and Computer Engineering Faculty Research & Creative Works

Three networks are compared for low false alarm stock trend predictions. Short-term trends, particularly attractive for neural network analysis, can be used profitably in scenarios such as option trading, but only with significant risk. Therefore, we focus on limiting false alarms, which improves the risk/reward ratio by preventing losses. To predict stock trends, we exploit time delay, recurrent, and probabilistic neural networks (TDNN, RNN, and PNN, respectively), utilizing conjugate gradient and multistream extended Kalman filter training for TDNN and RNN. We also discuss different predictability analysis techniques and perform an analysis of predictability based on a history of daily closing …

A Novel Thin Film Transistor Using Double Amorphous Silicon Active Layer, Jong Hyuni Choi, Chang-Soo Kim, Byung Cheon Lim, Jin Jang

Electrical and Computer Engineering Faculty Research & Creative Works

We have fabricated a novel low off-state leakage current thin-film transistor (TFT) using a chlorine incorporated amorphous silicon [a-Si:H(:Cl)] and amorphous silicon (a-Si:H) stacked active layer, in which conduction channel is formed in a-Si:H and a-Si:H(:Cl) is photo-insensitive material. The off-state photo-leakage current of the a-Si:H(:Cl)/a-Si:H TFT is much lower than that a conventional a-Si:H TFT.

An Improved Method For Incorporating Magnetic Saturation In The Q-D Synchronous Machine Model, Keith Corzine, Brian T. Kuhn, S. D. Sudhoff, H. J. Hegner

Electrical and Computer Engineering Faculty Research & Creative Works

An improved technique for incorporating saturation into the q-d axis model (Park''s model) of a synchronous machine is proposed. By choosing magnetizing flux linkage as a state variable, iterative procedures required by traditional methods are avoided. The saturation function is represented by an arctangent function which has some distinct advantages over polynomial representations and look-up tables. In particular, the parameters of the proposed function all have physical significance and the proposed function is defined over an infinite range of flux linkage. The model is verified for steady-state and transient conditions using a laboratory synchronous machine-rectifier system similar to those commonly …

Dc Link Stabilized Field Oriented Control Of Electric Propulsion Systems, Keith Corzine, S. D. Sudhoff, Steven F. Glover, H. J. Hegner, H. N. Robey

Electrical and Computer Engineering Faculty Research & Creative Works

Induction motor based electric propulsion systems can be used in a wide variety of applications including locomotives, hybrid electric vehicles, and ships. Field oriented control of these drives is attractive since it allows the torque to be tightly and nearly instantaneously controlled. However, such systems can be prone to negative impedance instability of the DC link. This paper examines this type of instability and sets forth a readily implemented albeit nonlinear control strategy to mitigate this potential problem.

Emc Applications Of The Emap5 Hybrid Fem/Mom Code, Yun Ji, Todd H. Hubing, Mohammad Wares Ali

Electrical and Computer Engineering Faculty Research & Creative Works

EMAP5 is a numerical software package designed to model electromagnetic problems. It employs the finite element method (FEM) to analyze three-dimensional volumes, and the method of moments (MOM) to analyze the current distribution on the surface of these volumes. The two methods are coupled through the fields on the dielectric surface. This paper describes the formulation of the EMAP5 code and demonstrates how it can be used to analyze simple printed circuit board configurations

Messages Of Individualism In French, Spanish, And American Television Advertising, Ronald E. Taylor, Joyce M. Wolburg

College of Communication Faculty Research and Publications

Individualism is a central value in French, Spanish, and American cultures. However, what it means to be an individual and how this is expressed varies among cultures. This study explores the ways that television advertising reflects individualism in French, Spanish, and American cultures and uses a qualitative approach that allows coding categories to emerge from the three countries' samples rather than imposing previously defined categories from a single culture. The study identifies six main advertising message strategies across the three cultures: the Efficient Individual, the Sensual Individual, the Attractive/Healthy Individual, the Esteemed Individual, the Performant(e) Individual, and the Intellectual Individual. …

Terminal Sedation As Palliative Care: Revalidating A Right To A Good Death, George P. Smith Ii

Scholarly Articles

Not everyone finds a “salvific meaning” in suffering. Indeed, even those who do subscribe to this interpretation recognize the responsibility of each individual to show not only sensitivity and compassion but render assistance to those in distress. Pharmacologic hypnosis, morphine intoxication, and terminal sedation provide their own type of medical “salvation” to the terminally ill patient suffering unremitting pain. More and more states are enacting legislation that recognizes this need of the dying to receive relief through regulated administration of controlled substances. Wider legislative recognition of this need would go far toward allowing physicians, in the exercise of their reasonable …

Reconceiving The Role Of Section 8(B)(1)(A): 1947–1997: An Essay On Collective Empowerment And The Public Good, Roger C. Hartley

Scholarly Articles

The Taft-Hartley section 8(b)(1)(A)s union discipline cases are linked to the impending collapse of collective bargaining in two ways. At one level, they have helped cause it by denying union majorities an important tool to enforce solidarity during economic disputes with employers and thereby have contributed to the loss of worker empowerment. At another level, the union discipline cases reflect certain shifts in national sentiments with respect to the role of unions and collective bargaining in general and the accommodation of collective bargaining to the competing claims of individuals and employers in particular. This paper is about both linkages.

Composition And Environmental Assessment Of Soils From United Arab Emirates, Torfa Alsheba Khames Alsheriani

Theses

The study focuses on the mineral and chemical composition, the textural characters and environmental assessment of some soils from the UAE. About forty soil samples were collected from AI Ain District and the Eastern Mountain District. Soils in AI Ain and its suburb are strongly influenced by the aeolian sedimentation, while those of the Eastern Mountain are formed in narrow valleys strikingly close to ophiolitic hinterland.

The studied soils· are remarkably impoverished in clay size fraction and clay minerals as well. This is due to the impeded chemical weathering under the prevailing arid climate. Corroborative techniques including X-ray diffraction, infrared …

Determining Capture Zones For Three-Dimensional, Heterogeneous, Anisotropic Aquifers By Monte Carlo Analysis, Jon Paul Jones

Theses and Dissertations

Most methods of delineating capture zones for pump-and-treat remedial design and wellhead protection assume a two-dimensional, homogeneous aquifer. Aquifers, however, are three-dimensional and heterogeneous, thereby introducing uncertainty in capture zone analysis. This study used a Monte Carlo analysis of three sets of statistical parameters defining aquifer heterogeneity. Each set had a different variance for the mean natural log hydraulic conductivity, which varied among the sets by a factor of four. The ensemble means of the capture zones for each set were estimated from 10 randomly generated fields with 12 layers each which were superimposed on each other for a total …

The Stigma Of Obesity : Beliefs About And Attitudes Toward Fat/Obese Persons, Sally Jean Clute

Dissertations and Theses

This research explores the relationship between beliefs about and attitudes toward fat/obese persons, specifically in regard to issues of attribution and perceived responsibility for the physical condition. The purpose of the research is to assess the extent to which fat/obese persons are derogated, given whether or not they are perceived to be held responsible for their fatness/obesity. It utilizes attribution theory (Heider, 1958; Jones & Davis, 1965; Kelley, 1967; Weiner, 1986), in particular, internal locus of control and issues of consensus and distinctiveness (Kelley, 1967) and controllability (Weiner, 1986). The main hypothesis is that fat/obese people will be viewed more …

Using A Realistic Job Preview To Communicate Organizational Culture, Johanna Glode

Dissertations and Theses

The present study sought to determine how organizational culture information could best be presented to job applicants for the purpose of attracting employees who will fit into an organization's culture. Attraction to the organization's culture was hypothesized to influence applicant self-selection into the company. Two different types of Realistic Job Previews (RJPs), semantic and episodic, were compared in their ability to convey information accurately about a hypothetical organizational culture. Participant knowledge of the culture was hypothesized to align objective, or actual, fit with subjective perceptions of fit.

Knowledge of the organization's culture, objective fit, subjective fit, attractiveness of the culture, …

Soil Catenas On Glacial Moraines Of The Central Oregon Cascades, Jason Erik Haugland

Dissertations and Theses

Soil development of two catenas in the central Oregon Cascades near Sisters, Oregon was examined on the Suttle Lake (Late Wisconsin age) (44° 25' N, 121 ° 43' W) and the Jack Creek (lllinoian age) moraines (44° 28' N, 121 ° 41' W) with regard to the factors of time as well as slope position.

Soils on both catenas are classified as Typic Vitricryands, regardless of slope position. The uniformity of soil classification suggests a limited development, perhaps the result of localized volcanic activity (Blue Lake event, 3500 YBP) adding pyroclastic material to the soils and retarding soil development. High …

Specification-Driven Optimization, Sheena Day

Dissertations and Theses

Traditionally, optimizing transformations have been built into compilers. The end-user has little or no control over guiding any optimizations that may be applied by the compiler. Moreover, the compiler-writer does not have a simple way to direct the optimizations. Thus, many potentially beneficial opportunities for code optimization may be lost. We have built a system that allows the user to participate in guiding source-to-source transformations via the specification of rewrite rules. A clean separation of the rules from the strategy of applying them makes the system easier to use and modify, compared to other integrated systems. This is especially relevant …
