A Contrast-Based Neural Control System For Ant Navigation, Joanna R. Wares, Predrag-Peter Ilich, Daniel P. Dougherty Jan 2003

A Contrast-Based Neural Control System For Ant Navigation, Joanna R. Wares, Predrag-Peter Ilich, Daniel P. Dougherty

Department of Math & Statistics Faculty Publications

A mathematical model for a neural control system of ant locomotion was developed. Contrast-based detectors using excitation and inhibition were tuned to specific contrast orientations. A control system using multiple orientation contrast detectors was then developed and optimized for a model ant, which could move via a biased random walk. The system allowed sufficient control to guide the ant through various mazes.

The Peace And Security Council Of The African Union: The Known Unknowns, Jeremy I. Levitt Jan 2003

The Peace And Security Council Of The African Union: The Known Unknowns, Jeremy I. Levitt

Journal Publications

The protocol establishing the Peace and Security Council of the African Union (AUPSC Protocol) will likely come into force in 2004 and will serve as the continent's first continent-wide, regional, collective security system. This article examines how African states chose to evolve the African Union regional collective security system. Particular attention is devoted to the concept of conflict management through military intervention in the AUPSC Protocol and relevant constitutive acts of African regional organizations. The first section analyzes key provisions of the Protocol. The second section contemplates the impact of the Protocol once it enters into force and the main …

The Origin Of Armstrong's Hot Fives And Hot Sevens, Gene H. Anderson Jan 2003

The Origin Of Armstrong's Hot Fives And Hot Sevens, Gene H. Anderson

Music Faculty Publications

It has been almost fifty years since Louis Armstrong's Hot Five and Hot Seven recordings of 1925-1928 were first recognized in print as a watershed of jazz history and the means by which the trumpeter emerged as the style's first transcendent figure. Since then these views have only intensified. The Hot Fives and Hot Sevens have come to be regarded as harbingers of all jazz since, with Armstrong's status as the “single most creative and innovative force in jazz history” and an “American genius” now well beyond dispute. This study does not question these claims but seeks, rather, to determine …

Smoke And Mirrors Or Science? Teaching Law With Computers - A Reply To Cass Sunstein On Artificial Intelligence And Legal Science, Eric Engle Jan 2003

Smoke And Mirrors Or Science? Teaching Law With Computers - A Reply To Cass Sunstein On Artificial Intelligence And Legal Science, Eric Engle

Richmond Journal of Law & Technology

The application of computer science in the law has largely, and productively, centered on educational programs and programs generating and managing databases and data management. Some limited work, however, has been done in the use of artificial intelligence (“AI”) to present models of legal decision-making. The majority of the work involving AI in the law, as the majority of work in AI generally, has focused on developing expert systems. An expert system attempts to solve one problem, or one class of problems well and should be distinguished from general systems, which seek to solve any problem. While databases and didactic …

Protecting Children From Pornography On The Internet: Freedom Of Speech Is Pitching And Congress May Strike Out, Dawn S. Conrad Jan 2003

Protecting Children From Pornography On The Internet: Freedom Of Speech Is Pitching And Congress May Strike Out, Dawn S. Conrad

Richmond Journal of Law & Technology

The Internet provides the First Amendment’s “freedom of speech” with a world of opportunity. Any person with access to the Internet may take advantage of a wide variety of information and communication methods. This unique medium, known to its users as cyberspace, is located in no particular geographical location and has no centralized control point, but is available to anyone, anywhere in the world with access." In the past twenty years, the Internet, a network of connected computers, has experienced extraordinary growth. The number of “host” computers, or those that store information and relay communications, increased between the years of …

The Academy Chokes On Food Biotech, Public Policy Suffocates, Henry I. Miller Jan 2003

The Academy Chokes On Food Biotech, Public Policy Suffocates, Henry I. Miller

Richmond Journal of Law & Technology

The National Academy of Sciences, under its 1863 congressional charter, is supposed to be dedicated to “investigate, examine, experiment, and report upon any subject of science or art whenever called upon to do so by any department of the government.” At least insofar as judging the scienti c integrity of governmental regulation of biotechnology is concerned, however, two recent “expert” committees of the National Research Council (NRC), the research arm of the Academy, have been plagued by apparent bias, and their recommendations have been dubious.

Saving "Cinderella": History And Story In Ashpet And Ever After, Elisabeth Rose Gruner Jan 2003

Saving "Cinderella": History And Story In Ashpet And Ever After, Elisabeth Rose Gruner

English Faculty Publications

An orphan is mistreated by a cruel surrogate family. The orphan is special, however, and with the intervention of kind and magical parental substitutes, rises to dizzying heights and achieves a happy ending. It’s a familiar tale, from “Cinderella” to Harry Potter —the difference is all in the details. In two fairy tale films of the 1980s and 1990s, those details remove the Cinderella story from the realm of fantasy. Ashpet and Ever After take pains to “realize” Cinderella—to remove almost all elements of magic and fantasy and to imagine, instead, what might make such a story real. Both incorporate …

Electrical Characteristics Of Si Doped With Sb By Laser Annealing, Raid A. Ismail, Aseel A. Hadi Jan 2003

Electrical Characteristics Of Si Doped With Sb By Laser Annealing, Raid A. Ismail, Aseel A. Hadi

Turkish Journal of Physics

Laser induced diffusion of antimony in silicon was obtained using a Nd:YAG pulsed laser. The irradiation of antimony-coated silicon by laser beam allowed melting and diffusion of antimony inside the silicon. Diodes were fabricated. Laser beam energy and substrate temperature played a major role in electrical sheet conductivity I-V, and C-V characteristics of the fabricated diodes. High laser energy reduced the electrical sheet conductivity and dominated the recombination current due to the generation-recombination process and trapping centers. On the other hand, the diffusion current dominated for diodes fabricated under heating conditions of the sample during laser irradiation. The C-V measurements …

Electron Transport Mechanism In Gan/Algan Hemt Structures, Si̇bel Gökden Jan 2003

Electron Transport Mechanism In Gan/Algan Hemt Structures, Si̇bel Gökden

Turkish Journal of Physics

The electron transport mechanism in GaN/AlGaN HEMT (High Electron Mobility Transistors) structures grown with MBE on sapphire substrate was investigated by using the temperature dependence of the Hall coefficient, resistivity, carrier density and Hall mobility. Hall measurements were carried out using Van der Pauw geometry. From the LO-phonon-scattering-limited component of the mobility, we obtain LO phonon energy \hbar \omega \approx 90 meV and the momentum relaxation time of \tau_{m} \approx 4 fs. Also, from the temperature dependence of the 2D carrier density, we obtain the donor activation energy E_{a} \approx 29 meV.
