Prediction Of Electric Load Using Kohonen Maps - Application To The Polish Electricity Consumption, Amaury Lendasse, M. Cottrell, V. Wertz, M. Verleysen

Engineering Management and Systems Engineering Faculty Research & Creative Works

The Problem of Electrical Load Forecasting Presents Some Particularities, Compared to the Generic Problem of Time-Series Prediction. One of These Particularities is that Several Values (Corresponding to One Day of Consumption) Are Usually Expected as the Result of the Prediction. in This Paper, We Propose an Original Method Dividing the Problem into Three Parts: Prediction of the Daily Mean, of the Daily Standard Deviation and of the Normalized Daily Profile. for the Mean and the Standard Deviation, Radial Function Networks Are Used as Nonlinear Approximations. for the Normalized Profile, a Method based on Kohonen Maps is Proposed. This Method is …

Lawyers And The Practice Of Workplace Equity, Susan Sturm

Faculty Scholarship

Lawyers involved in the pursuit of workplace equity are difficult to pigeon-hole. Of course, the practice of many employment lawyers conforms to conventional understandings of lawyers' roles. These lawyers litigate cases on behalf of management or employees, advise clients about their legal rights and obligations, and define their mission as avoiding liability or winning battles in court.But innovators have crafted interesting and dynamic roles that transcend the traditional paradigm. These innovators connect law, as it is traditionally understood, to the resolution of the underlying problems that create and maintain workplace inequity. Civil rights lawyers working in both public and private …

Magnetoacoustic Chemical Sensors Based On Swellable Polymer Microspheres, Huqun Liu

Doctoral Dissertations

The goal of this dissertation was to investigate chemical applications of magnetoacoustic sensors based on swellable polymer microspheres. The magnetoacoustic sensor was used to monitor viscosity of starch solution, water loading, and 2-hydroxyethyl methacrylate polymerization.

Poly(vinylbenzyl chloride) (polyVBC) microspheres were prepared by suspension polymerization and then derivatized to introduce dicarboxylate groups onto the polymer backbone. Poly(vinylbenzyl chloride-trichlorophenyl acrylate) (polyVBC-TCPA) microspheres were prepared by dispersion polymerization and then derivatized to introduce amine groups onto the polymer backbone. These derivatized polymer microspheres swell and shrink with changing pH. They were entrapped in a hydrogel membrane and the membrane turbidity was investigated by …

Mass Transfer Reactions And Decay Sinks For Disinfectants In Water Distribution Systems, Jeremy B. Jones

Civil & Environmental Engineering Theses & Dissertations

Treatment plants utilize chlorine and chloramine both as a primary disinfectant for water purification and a secondary disinfectant for distribution system protection. The treatment goal is that the disinfectant residual be present throughout the distribution system until it reaches the customer's tap. Maintaining a residual throughout the system is critical for providing pathogen-free water and protecting human health. Therefore, water utility authorities are very interested in how disinfectants such as chlorine and chloramine decay as they travel through a water distribution system.

Current mathematical models typically divide the decay into two distinct phases. There is (1) decay occurring in the …

Active And Adaptive Flow Control Of Twin-Tail Buffet And Applications, Zhi Yang

Mechanical & Aerospace Engineering Theses & Dissertations

Modern fighter aircraft with dual vertical tails are operated at high angles of attack. The vortex generated by leading edge extension (LEX) breaks down before reaching the two vertical tails. The wake of highly unsteady, turbulent flow causes unbalanced broadband aerodynamic loading on the tails and may produce severe buffet on the tails and lead to tail fatigue failure.

Flow suction along the vortex cores (FSVC) is investigated as an active control method for tail-buffet alleviation. Suction tubes have been tilted at different angles to study the control effectiveness of suction tubes orientation. Flow field response, aerodynamic loading and aeroelastic …

Federating Heterogeneous Digital Libraries By Metadata Harvesting, Xiaoming Liu

Computer Science Theses & Dissertations

This dissertation studies the challenges and issues faced in federating heterogeneous digital libraries (DLs) by metadata harvesting. The objective of federation is to provide high-level services (e.g. transparent search across all DLs) on the collective metadata from different digital libraries. There are two main approaches to federate DLs: distributed searching approach and harvesting approach. As the distributed searching approach replies on executing queries to digital libraries in real time, it has problems with scalability. The difficulty of creating a distributed searching service for a large federation is the motivation behind Open Archives Initiatives Protocols for Metadata Harvesting (OAI-PMH). OAI-PMH supports …

Definability, Canonical Models, And Compactness For Finitary Coalgebraic Modal Logic, Alexander Kurz, Dirk Pattinson

Engineering Faculty Articles and Research

This paper studies coalgebras from the perspective of the finitary observations that can be made of their behaviours. Based on the terminal sequence, notions of finitary behaviours and finitary predicates are introduced. A category Behω(T) of coalgebras with morphisms preserving finitary behaviours is defined. We then investigate definability and compactness for finitary coalgebraic modal logic, show that the final object in Behω(T) generalises the notion of a canonical model in modal logic, and study the topology induced on a coalgebra by the finitary part of the terminal sequence.

Modal Predicates And Coequations, Alexander Kurz, Jiří Rosický

Engineering Faculty Articles and Research

We show how coalgebras can be presented by operations and equations. This is a special case of Linton’s approach to algebras over a general base category X, namely where X is taken as the dual of sets. Since the resulting equations generalise coalgebraic coequations to situations without cofree coalgebras, we call them coequations. We prove a general co-Birkhoff theorem describing covarieties of coalgebras by means of coequations. We argue that the resulting coequational logic generalises modal logic.

Mediating Ethically: The Limits Of Codes Of Conduct And The Potential Of A Reflective Practice Model, Julie Macfarlane

Osgoode Hall Law Journal

Discussions regarding the appropriate ethical behaviours for mediators and the subsequent development of formal codes of conduct have focused on hallmark issues such as third party impartiality and party self-determination. However, in an informal process, ethical choices are inherent in every intervention made by a mediator. In adopting the standard-setting approach of an adjudicative model, mediator codes of conduct are a poor fit with the conceptual and structural characteristics of this fluid, uncertain, and essentially private process. Confining the substantive and conceptual debate over mediation ethics to formal codes dangerously underestimates both the scope and the significance of choices faced …

Theft Of Time: Disciplining Through Science And Law, Laureen Snider

Osgoode Hall Law Journal

This commentary traces the genealogy of "theft of time," a newly discovered offence committed by employees against employers. A Foucauldian perspective is used to examine how truth claims from science, technology, and law constitute categories through which groups are sorted, classified, and censured: the processes of naming, blaming, and shaming. This commentary argues that to understand why some truth claims are heard and acted upon, while others are ignored or silenced, it is necessary to link the power/knowledge nexus to political economy, the structural dominance of capital, and the power relations thereby created and reinforced.

Separation And Interpretation, Philip A. Hamburger

Faculty Scholarship

Should the establishment clause be interpreted in terms of "separation between church and state"? If not, how should the establishment clause be interpreted?

At stake, first, is the character of religious freedom in the United States. In particular, will lingering separationist notions continue to affect the interpretation of the First Amendment? Notwithstanding the claims made on behalf of separation, there is reason to fear that it is not the religious freedom guaranteed by the First Amendment. Indeed, it will be seen that the interpretation of the First Amendment in terms of "separation of church and state" has tangibly diminished this …

Erwin Griswold's Tax Law – And Ours, Michael J. Graetz

Faculty Scholarship

It is a pleasure for me to be here today to deliver the Erwin N. Griswold Lecture. And it is an honor to follow those who have graced this lectern before me. They include important mentors to me. Several are close friends. Today, we are in a quiet interlude awaiting the next serious political debate about restructuring the nation's tax system. No fundamental tax policy concerns are at stake in the current disputes over economic stimulus or in the political huffing and puffing about postponing or accelerating the income tax rate cuts of the 2001 Act. Those arguments are concerned …

Facing The Urban Future After September 11, 2001, Richard Briffault

Faculty Scholarship

In this essay I would like to address briefly four issues of importance to local governments raised by the September 11 attack and its aftermath. These issues are the role of local governments in addressing questions of public safety and preparedness; the relations among local governments within a region in responding to terrorism; the role of the federal government in the local response to terrorism; and the implications of September 11 for the structures and functions of local government. These issues are interconnected. Certainly, an effective local response to the public safety challenge posed by terrorism will require more coordinated …

Understanding Enron: "It's About Gatekeepers, Stupid", John C. Coffee Jr.

Faculty Scholarship

What do we know after Enron's implosion that we did not know before it? The conventional wisdom is that the Enron debacle reveals basic weaknesses in our contemporary system of corporate governance. Perhaps, this is so, but where is the weakness located? Under what circumstances will critical systems fail? Major debacles of historical dimensions – and Enron is surely that – tend to produce an excess of explanations. In Enron's case, the firm's strange failure is becoming a virtual Rorschach test in which each commentator can see evidence confirming what he or she already believed.

Patent Signals, Clarisa Long

Faculty Scholarship

Courts and commentators often treat intellectual property as if the private value of the rights stemmed entirely from the control legal rules conferred over the protected subject matter. While the literature has devoted an enormous amount of time, paper, and ink to the discussion of whether legal rules grant the optimal amount of exclusivity, it has not considered whether it has been examining all the functions of patents This Article provides a new general framework for analyzing the function and effect of intellectual property rules. Rather than focusing on patents as a mechanism for privatizing information, this Article instead frames …

Trade And Poverty In The Poor Countries, Jagdish N. Bhagwati, T.N. Srinivasan

Faculty Scholarship

While freer trade, or “openness” in trade, is now widely regarded as economically benign, in the sense that it increases the size of the pie, the recent anti-globalization critics have suggested that it is socially malign on several dimensions, among them the question of poverty.

Their contention is that trade accentuates, not ameliorates, and that it deepens, not diminishes, poverty in both the rich and the poor countries. The theoretical and empirical analysis of the impact of freer trade on poverty in the rich and in the poor countries is not symmetric, of course. We focus here only on the …

School Vouchers And Religious Liberty: Seven Questions From Madison's Memorial And Remonstrance, Vincent A. Blasi

Faculty Scholarship

In the immediate aftermath of the Revolutionary War, many upstanding citizens of the fledgling state of Virginia were not pleased. They were, in fact, appalled by the decline they perceived in the state of public morals. Newspaper editorials, sermons, and speeches in public assemblies resounded with references to the recent upsurge in gambling, whoring, cockfighting, and public drunkenness. That such departures from the straight and narrow are not uncommon in postwar periods, following all the social dislocations of military mobilization, was no consolation to Virginians eager to show a doubting world that government by the people could work.

The root …

Surface Micromachined Force Gauges: Uncertainty And Reliability, Jonathan W. Wittwer, Troy Gomm, Larry L. Howell

Faculty Publications

Surface micromachining of micro-electro-mechanical systems (MEMS), like all other fabrication processes, has inherent variation that leads to uncertain material and dimensional parameters. By considering the effects of these variations during the design of micro force gauges, the gauge uncertainty and reliability can be estimated. Without means of calibrating micro gauges, these effects are often significant when compared to experimental repeatability. The general force gauge model described in this paper can be used to measure a wide range of forces, and simple design changes can lead to improved accuracy in measurement. A method of probabilistic design is described that is not …

Evaluation Of A Compound Probability Model With Tower-Mounted Scatterometer Data, David G. Long, Benjamin E. Barrowes

Faculty Publications

Six months of data from the YSCAT94 experiment conducted at the CCIW WAVES research platform on Lake Ontario, Canada, are analyzed to evaluate a compound probability model. YSCAT was an ultrawideband small footprint (ap 1 m) microwave scatterometer that operated at frequencies of 2-18 GHz, incidence angles from 0° to 60°, both h-pol and v-pol, and which tracked the wind using simultaneous weather measurements. The probability distribution function of the measured instantaneous backscattered amplitude (p(a)) is compared to theoretical distributions developed from-the composite model and a simple wave spectrum. Model parameters of the resulting Rayleigh/generalized lognormal distribution probability density function …
