Software Development In The Grid: The Damien Tool-Set, Edgar Gabriel, Rainer Keller, Peggy Lindner, Matthias S. Müller, Michael M. Resch

Engineering Management and Systems Engineering Faculty Research & Creative Works

The development of applications for Grid-environments is currently lacking the support of tools, which end-users are familiar with from their regular working environment. This paper analyzes the requirements for developing, porting and optimizing scientific applications for Grid-environments. A toolbox designed and implemented in the frame of the DAMIEN project which closes some of the gaps and supports the end-user during the development of the application and its day-to-day usage in Grid-environments is then presented. © Springer-Verlag Berlin Heidelberg 2003.

Adaptive Critic Neural Network-Based Controller For Nonlinear Systems With Input Constraints, Pingan He, Sarangapani Jagannathan

Electrical and Computer Engineering Faculty Research & Creative Works

A novel adaptive critic-Based multilayer neural network (NN) controller in discrete-time is designed to deliver a desired tracking performance for a class of nonlinear systems in the presence of magnitude constraints on the input. Reinforcement learning scheme in discrete time is proposed for the NN controller, where the action generating NN learning is performed based on a certain performance measure, which is supplied from a critic. using the Lyapunov approach and with a novel weight update, the uniform ultimately boundedness (UUB) of the closed loop tracking error and weight estimates are shown. the adaptive critic NN does not require an …

Million City Traveling Salesman Problem Solution By Divide And Conquer Clustering With Adaptive Resonance Neural Networks, Samuel A. Mulder, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

The Traveling Salesman Problem (TSP) is a very hard optimization problem in the field of operations research. It has been shown to be NP-complete and is an often-used benchmark for new optimization techniques. One of the main challenges with this problem is that standard, non-AI heuristic approaches such as the Lin-Kernighan algorithm (LK) and the chained LK variant are currently very effective and in wide use for the common fully connected, Euclidean variant that is considered here. This paper presents an algorithm that uses adaptive resonance theory (ART) in combination with a variation of the Lin-Kernighan local optimization algorithm to …

Definition Of A Robustness Metric For Resource Allocation, Shoukat Ali, A. A. Maciejewski, Howard Jay Siegel, Jong-Kook Kim

Electrical and Computer Engineering Faculty Research & Creative Works

Parallel and distributed systems may operate in an environment that undergoes unpredictable changes causing certain system performance features to degrade. Such systems need robustness to guarantee limited degradation despite fluctuations in the behavior of its component parts or environment. This research investigates the robustness of an allocation of resources to tasks in parallel and distributed systems. The main contributions of this paper are (1) a mathematical description of a metric for the robustness of a resource allocation with respect to desired system performance features against perturbations in system and environmental conditions, and (2) a procedure for deriving a robustness metric …

Probabilistic Neural Networks For Multi-Class Tissue Discrimination With Gene Expression Data, Rui Xu, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

With the emergence and rapid advancement of DNA microarray technologies, construction of gene expression profiles for different cancer types has already become a promising means for cancer diagnosis and treatment. Most previous research has focused on binary classification. Here, we use a probabilistic neural network (PNN) for multi-classification of cancer data. The experimental results demonstrate the effectiveness of the PNN in addressing gene expression data.

Implementation Of Adaptive Critic-Based Neurocontrollers For Turbogenerators In A Multimachine Power System, Ganesh K. Venayagamoorthy, Donald C. Wunsch, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents the design and practical hardware implementation of optimal neurocontrollers that replace the conventional automatic voltage regulator (AVR) and the turbine governor of turbogenerators on multimachine power systems. The neurocontroller design uses a powerful technique of the adaptive critic design (ACD) family called dual heuristic programming (DHP). The DHP neurocontroller's training and testing are implemented on the Innovative Integration M67 card consisting of the TMS320C6701 processor. The measured results show that the DHP neurocontrollers are robust and their performance does not degrade unlike the conventional controllers even when a power system stabilizer (PSS) is included, for changes in …

When Terrorism Threatens Health: How Far Are Limitations On Personal And Ecomonic Liberties Justified, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The government is engaged in a homeland-security project to safeguard the population's health from potential terrorist attacks. This project is politically charged because it affords the state enhanced powers to restrict personal and economic liberties. Just as governmental powers relating to intelligence, law enforcement, and criminal justice curtail individual interests, so too do public health powers.

Can Federal Agencies Authorize Private Suits Under Section 1983 - A Theoretical Approach, Brian Galle

Georgetown Law Faculty Publications and Other Works

This Article offers a few thoughts on the theory of regulatory enforcement under § 1983. Section 1983, I argue, itself authorizes federal agencies to make their regulations privately enforceable. In recent years, the Supreme Court has announced that federal norms are unenforceable in the absence of clear statutory authorization - a "clear statement rule" for private rights of action. Drawing on key tenets of modern statutory interpretation, I claim that the plain text of § 1983 allows many federal regulations to meet this test. Because § 1983 has an important function in coordinating state regulatory efforts with federal law, a …

Erasure And Recognition: The Census, Race And The National Imagination, Naomi Mezey

Georgetown Law Faculty Publications and Other Works

This Article is concerned with the constitutive power of the census with respect to race. It is an examination of the U.S. Census as an aspect of what Angela Harris calls race law, "law pertaining to the formation, recognition, and maintenance of racial groups, as well as the law regulating the relationships among these groups." While others have noted and explored the epistemological and constitutive functions of the census race categories, my aim is to unpack this insight in the context of two specific examples of categorical change and contest: the addition of a Chinese racial category in 1870 and …

Proposed Legislation On Judicial Election Campaign Finance, Roy A. Schotland

Georgetown Law Faculty Publications and Other Works

In light of the recent extraordinary rise in judicial campaign spending, illustrated in Ohio's 2000 judicial elections (and elsewhere, and in Ohio again in 2002), we must consider improving the Model Code of Judicial Conduct. The 1999 amendments to the Code addressed campaign finance, but did not address two major problems. The first one is the absence of limits on aggregate contributions from law firms; only Texas has such limits. This gap allows large contributions from law firms to go to judges presiding in cases in which those firms participate, circumventing the recusal and disqualification triggers. The second problem is …

The Difference In Criminal Defense And The Difference It Makes, Abbe Smith

Georgetown Law Faculty Publications and Other Works

My own view of criminal defense lawyering owes much to Monroe Freedman. I agree with his "traditionalist view”, of criminal defense ethics as a lawyering paradigm in which zealous advocacy and the maintenance of client confidence and trust are paramount. Simply put, zeal and confidentiality trump most other rules, principles, or values. When there is tension between these "fundamental principles” and other ethical rules, criminal defense lawyers must uphold the principles, even in the face of public or professional outcry. Although a defender must act within the bounds of the law, he or she should engage in advocacy that is …

Non-Judicial Review, Mark V. Tushnet

Georgetown Law Faculty Publications and Other Works

Professor Mark Tushnet challenges the view that democratic constitutionalism requires courts to dominate constitutional review. He provides three diverse examples of non-judicial institutions involved in constitutional review and examines the institutional incentives to get the analysis" right." Through these examples, Professor Tushnet argues that non-judicial actors may perform constitutional review that is accurate, effective, and capable of gaining public acceptance. Professor Tushnet recommends that scholars conduct further research into non-judicial review to determine whether ultimately more or less judicial review is necessary in constitutional democracies.

Common- And Differential-Mode Signaling And Filtering, Zhe Li

Masters Theses

"Common-mode chokes are widely used as suppression filters against interference of common-mode noise in high-speed differential signaling. This thesis focuses on investigating the characteristics of common-mode chokes. Mixed-mode S-parameters are presented as a useful concept for explaining the modal operation of differential circuits.

Three methods for measuring common-mode and differentia-mode S-parameters of common-mode chokes are demonstrated. The three methods involve (1) ABCD chain matrix, 2) using hybrid couplers and 3) modal decomposition. Each measurement method provides a specific level of accuracy. The modal decomposition method can work up to 10GHz.

SPICE equivalent circuit model of common-mode chokes and the extraction …

Modeling Of Infrared Radiation For All Skies From Easy-To-Measure Meteorological Parameters At Tropical Location: Ilorin, Nigeria, Sunday O. Udo

Turkish Journal of Physics

Downward infrared radiation (L) and some easy-to-measure meteorological variables (relative humidity, clearness index and vapour pressure) were collected for a period of two years at Ilorin. Downward infrared radiation data were obtained using a pyrgeometer (Eppley-PIR), while data for relative humidity and vapour pressure for Ilorin were obtained from the Nigerian Meteorological Services, Lagos. Based on these data, using statistical regression analysis, empirical models (seven one-variable and nine two-variable) for predicting daily mean infrared radiation, from both clear and cloudy skies, were tested. Their advantage is that they only make use of easily measured meteorological parameters. The best one-variable model …

Interaction Integrals Of Extended Bodies And Convolution/Folding Operation, Şule Kehnemi̇, R. Ömür Akyüz

Turkish Journal of Physics

The convolution, or folding, theorem related to Fourier transforms is applied to the evaluation of interaction integrals of certain extended bodies for the specific purpose of nuclear applications The integrals give analytical results for a class of functions when chosen from among uniform sharp and leptodermous spheres, delta-points, Yukawa, and Coulomb shapes. Such shapes are convenient to use as models for source density and point-point interaction.

Adiabatic Quantum Pumping Of Coherent Electrons, Ora Entin-Wohlman, Amnon Aharony, Vyacheslavs Kashcheyevs

Turkish Journal of Physics

We review recent theoretical calculations of charge transfer through mesoscopic devices in response to slowly-oscillating, spatially-confined, potentials. The discussion is restricted to non-interacting electrons, and emphasizes the role of quantum interference and resonant transmission in producing almost integer values (in units of the electronic charge e) of the charge transmitted per cycle, Q. The expression for the pumped charge is derived from a systematic expansion of the system scattering states in terms of the temporal derivatives of the instantaneous solutions. This yields the effect of the modulating potential on the Landauer formula for the conductance in response to a constant …

Persistent Currents In Mesoscopic Loops And Networks, Igor O. Kulik

Turkish Journal of Physics

The paper describes persistent (also termed ``permanent", or ``non-decaying") currents in mesoscopic metallic and macromolecular rings, cylinders and networks. The current arises as a response of system to Aharonov-Bohm flux threading the conducting loop and does not require external voltage to support the current. Magnitude of the current is periodic function of magnetic flux with a period of normal-metal flux quantum \Phi_0 = hc/e. Spontaneous persistent currents arise in regular macromolecular structure without the Aharonov-Bohm flux provided the azimuthal periodicity of the ring is insured by strong coupling to periodic background (a ``substrate"), otherwise the system will undergo the Peierls …

Mean Multiplicity Of Quark And Gluon Jets As A Function Of Opening Angle In E^{+}E^{-} \Rightarrow B\Overline{B} G Events, Ayda Beddall

Turkish Journal of Physics

A comparison of the properties of quark and gluon jets has been madeby Monte Carlo simulation of the reaction Z \rightarrow b \overline{b} g. The jet energy is held fixed for every 5 GeV between 15--30 GeV energies and the mean multiplicity of b-quark and gluon jets are obtained as function of the angle between them. It is seen that the jet properties not only depend on the jet energies but also on the angle between the jets.

Physical Properties Of Spray Pyrolysed Cds Thin Films, A. Ashour

Turkish Journal of Physics

Cadmium sulphide (CdS) thin films were prepared by chemical spray-pyrolysis technique. Cleaned glass substrates were used. The substrate temperature was varied in the range 200 -- 400 °C and seems to be one of the more important parameters affecting the physical properties of the semiconductor. The films were characterized by X-ray diffraction (XRD). XRD patterns indicated the presence of single-phase hexagonal CdS. The resistivity of the as-deposited films was found to vary in the range 10^3 - 10^5 \Omega. Cm, depending on the substrate temperature. Direct band gap values of 2.39--2.42 eV were obtained from optical absorption measurements.
