Effective Leadership Skills: The Development Of A Professional Improvement Plan, Maxine Woodside

Abraham S. Fischler College of Education ETD Archive

This applied dissertation represents a study of personal and professional leadership development. The study consists of reflective chronological accountings of influences on the writer from infancy to adulthood. The analysis highlights the opportunities in the early and formative years that support the development of a professional improvement plan.

The framework of this study was based on assessment results taken from the Florida Principal Competency Assessment (Florida Department of Education, 1995) and the Educational Leadership Appraisal (A. Ellis, 1993). More specifically, previous evaluations and reflections on previous leadership positions were used as a focus of professional growth. Based upon the results …

Query-Based Learning For Aerospace Applications, Donald C. Wunsch, Emad W. Saad, J. J. Choi, J. L. Vian

Electrical and Computer Engineering Faculty Research & Creative Works

Models of real-world applications often include a large number of parameters with a wide dynamic range, which contributes to the difficulties of neural network training. Creating the training data set for such applications becomes costly, if not impossible. In order to overcome the challenge, one can employ an active learning technique known as query-based learning (QBL) to add performance-critical data to the training set during the learning phase, thereby efficiently improving the overall learning/generalization. The performance-critical data can be obtained using an inverse mapping called network inversion (discrete network inversion and continuous network inversion) followed by oracle query. This paper …

This article describes an approach to bridge improvements that uses smart structures, introduces key technologies for health monitoring systems based on fiber optics and gives an overview of two instrumented bridges. A sensing system in one application monitors general performance and health of the structure, while the system in a second application interrogates the behavior of a major structural repair.

The Subcircuit Extraction Problem, Nian Zhang, Donald C. Wunsch, Frank Harary

Electrical and Computer Engineering Faculty Research & Creative Works

The steady down scaling of CMOS device dimensions has been the main stimulus to the growth of microelectronics and computer aided very large scale integration (VLSI) design. But the more an integrated circuit (IC) is scaled, the higher its packing density becomes. The increasing size of chips, measured in either area or number of transistors, and the waste of the large capital investment involved in fabricating and testing circuits that do not work, make layout analysis and verification an important part of physical design automation. The most efficient way to overcome these difficulties is to identify a related collection of …

Re-Imagining Justice, Robin West

Georgetown Law Faculty Publications and Other Works

What do we mean by legal justice, as opposed to distributive, or social, or political justice; what is the justice, that is, we hope law promotes? What is the justice that lawyers and judges, peculiarly, are professionally committed to pursue? What is the virtue around which, arguably, this profession, and the individuals within it, have defined their public lives?

Justice -- and more particularly legal justice -- is a badly under-theorized topic in jurisprudence; perhaps surprisingly, there is little written on it. The paucity of writing of course has a history. It can be traced to the turn of the …

A Discrete-Time Model For Spatio-Temporally Correlated Mimo Wssus Multipath Channels, Chengshan Xiao, Jingxian Wu, Sang-Yick Leong, Y. Rosa Zheng, Khaled Ben Letaief

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a statistical discrete-time model is proposed for simulating wideband MIMO channels which experience spatially and temporally correlated, widesense stationary uncorrelated scattering (WSSUS) multipath Rayleigh fading. A new method is also presented to efficiently generate the correlated MIMO channel coefficients, which can be used for accurate simulation of physical continuous-time MIMO channel. The statistic accuracy of the discrete-time MIMO channel model is rigorously verified through theoretical analysis and extensive simulations in different criteria.

A Numerical Investigation Of Interior Resonances In The Hybrid Fem/Mom Method, Yun Ji, Hao Wang, Todd H. Hubing

Electrical and Computer Engineering Faculty Research & Creative Works

The interior resonance problem that can occur when using a hybrid finite-element method/method of moments (FEM/MoM) method to model electromagnetic scattering problems is investigated. Calculations of the bistatic radar cross section of a coated dielectric sphere are presented using different formulations, solution approaches, and solvers. The solutions using the electric-field integral equation have significant errors near an interior resonance frequency. When the combined-field integral equation is employed, satisfactory solutions can be obtained that do not depend on the particular solution approach or solver.

An Extended Kalman Filter (Ekf) Approach On Fuzzy System Optimization Problem, Nian Zhang, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

Optimizing the membership functions of a fuzzy system can be viewed as a system identification problem for a nonlinear dynamic system. Basically, we can view the optimization of fuzzy membership functions as a weighted least-squares minimization problem, where the error vector is the difference between the fuzzy system outputs and the target values for those outputs. The extended Kalman filter algorithm is a good choice to solve this system identification problem, not only because it is a derivative-based algorithm that is suitable to solve the weighted least-squares minimization problem, but also because of its appealing predictor-corrector feature for nonlinear system …

The Original Meaning Of The Necessary And Proper Clause, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

In this Article, I present the evidence of the original public meaning of the Necessary and Proper Clause." These findings will, of course, be of interest to originalists. But, they should also be of interest to the many constitutional scholars who consider original meaning to be one among several legitimate modes of constitutional analysis, or who consider original meaning the starting point of a process by which this meaning is translated into contemporary terms. By either account, it is important to find the correct original meaning, even if it is not dispositive of today's cases and controversies. I will show …

Drm And Privacy, Julie E. Cohen

Georgetown Law Faculty Publications and Other Works

Interrogating the relationship between copyright enforcement and privacy raises deeper questions about the nature of privacy and what counts, or ought to count, as privacy invasion in the age of networked digital technologies. This Article begins, in Part II, by identifying the privacy interests that individuals enjoy in their intellectual activities and exploring the different ways in which certain implementations of DRM technologies may threaten those interests. Part III considers the appropriate scope of legal protection for privacy in the context of DRM, and argues that both the common law of privacy and an expanded conception of consumer protection law …

Security And Freedom: Are The Governments' Efforts To Deal With Terrorism Violative Of Our Freedoms?, David Cole

Georgetown Law Faculty Publications and Other Works

One of the most common things that is said about September 11th is that it changed everything. In some respects, that is true. In the most important respects it would be more accurate to say it has changed everything for some, far more than it has for others. One instance of that can be seen in a pole that National Public Radio did one year after September 11th. They asked people to what extent their life had changed. They asked them whether they had to give up any important rights or freedoms in the war on terrorism. Only seven percent …

The Joy Of Teaching Legislation, Chai R. Feldblum

Georgetown Law Faculty Publications and Other Works

I am going to talk about teaching legislation, a class I have taught several times at Georgetown University Law Center, as well as teaching a federal legislation clinic, which I founded ten years ago at the law school. Bill Eskridge has done a wonderful job laying out the different ways one can teach a course in legislation; you will see that my approach focuses on teaching the skills that, as Bill also correctly noted, all young lawyers will need when they start practicing.

Law In The Heart Of Darkness: Atrocity & Duress, Rosa Ehrenreich Brooks

Georgetown Law Faculty Publications and Other Works

Our faith in the law is rarely tested, since in America, at least, few of us ordinary people ever find ourselves at the extremes, confronting violence and terror. But the extremes have a way of creeping up on us, and the unimaginable can quickly and imperceptibly begin to seem routine. Millions of ordinary Europeans discovered this in the middle of the last century, and thousands of ordinary Americans discovered it in Vietnam. Some Americans are discovering it again today in the mountains and deserts of Afghanistan and Iraq. Experientially, there is often no sharp dividing line between "ordinary" life and …

Evolving Digital Circuits Using Particle Swarm, Ganesh K. Venayagamoorthy, Venu Gopal Gudise

Electrical and Computer Engineering Faculty Research & Creative Works

Particle swarm optimization (PSO) motivated by the social behavior of organisms is proposed for evolution of combinational logic circuits. Results are presented to show that PSO based evolution of digital circuits are equivalent to or even with better solutions (with minimum number of logic gates) than that of a human designer and other genetic algorithm (GA) based techniques. This PSO based approach converges faster than other approaches reported in literature using genetic algorithms and as a result the computational intensity involved in hardware evolution is reduced. Examples taken from the literature are used to evaluate the performance of the proposed …

Fatigue Testing Of A Composite Propeller Blade Using Fiber-Optic Strain Sensors, Steve Eugene Watkins, V. E. Zetterlind Iii, M. W. Spoltman

Electrical and Computer Engineering Faculty Research & Creative Works

The performance of surface-mounted extrinsic Fabry-Perot interferometric (EFPI) sensors during a seventeen-million-cycle, high-strain fatigue test is reported. Fiber-optic strain measurements did not degrade during the test. The sensors were applied to a composite propeller blade subject to a constant axial load and a cyclic bending load. Strain measurements were taken at four blade locations using two types of EFPI sensors and co-located electrical resistance strain gages. Static and dynamic strain measurements were taken daily during the 65 days of this standard propeller-blade test. All fiber-optic sensors survived the fatigue test while most of the resistive gages failed. The suitability of …

Impedance Boundary Conditions In A Hybrid Fem/Mom Formulation, Hao Wang, Minjia Xu, Chen Wang, Todd H. Hubing

Electrical and Computer Engineering Faculty Research & Creative Works

When numerically modeling structures with imperfect conductors or conductors coated with a dielectric material, impedance boundary conditions (IBCs) can substantially reduce the amount of computation required. This paper incorporates the IBC in the finite-element method (FEM) part of a FEM/method of moments (FEM/MoM) modeling code. Properties of the new formulation are investigated and the formulation is used to model three practical electromagnetic problems. Results are compared to either measured data or other numerical results. The effect of the IBC on the condition number of hybrid FEM/MoM matrices is also discussed.

Measurement Of Mode Patterns In A High-Power Microwave Cavity, Sergey Kharkovsky, U. C. Hasar

Electrical and Computer Engineering Faculty Research & Creative Works

A wet thermal paper method for measuring of mode patterns and heat distributions in a high-power microwave multimode cavity is developed. The exposure time of the paper is evaluated. It is shown that this method allows measuring and recording mode patterns in the loaded and unloaded cavity, and the heat distribution inside the cavity with a load movement. The mode patterns and heat distributions along horizontal and vertical planes of the cavity are presented. Possible applications of the method in medicine and biology are discussed, and a calibration protocol of a microwave oven for microwave radiation exposure on cell cultures …

Rogue Science, Maxwell Gregg Bloche

Georgetown Law Faculty Publications and Other Works

This review essay considers the tension between the evidence-driven vision of science's mission and the fears of malicious use and terrible consequences that have come to the fore since the terrorist attacks of September 11, 2001. These fears have led some to call for government restrictions on the substance of scientific research and communication. In general, this approach is likely to do far more harm than good. But scientists need to take the problem of social consequences more seriously than they have so far. The author argues in this essay that in some circumstances, when rogue use of science can …

Analysis Of Simple Two-Capacitor Low-Pass Filters, Todd H. Hubing, David Pommerenke, Theodore M. Zeeff, Thomas Van Doren

Electrical and Computer Engineering Faculty Research & Creative Works

The performance of typical low-pass capacitor filters is limited by the mutual inductance between the input and output sides of the filter. This paper describes how two appropriately spaced capacitors can be used to construct a low-pass filter with significantly better high-frequency performance than a one-capacitor filter. Laboratory measurements and numerical simulations are used to quantify the mutual inductance and compare the performance of one- and two-capacitor low-pass filters.
