High-Power Microwave Wideband Random Signal Measurement And Narrowband Signal Detection Against The Noise Background, Marina Koledintseva, Alexander A. Kitaytsev, V. A. Konkin

Electrical and Computer Engineering Faculty Research & Creative Works

A method of both measurement of power parameters of a microwave wideband intense random signal and detection of a narrow-band signal with unknown frequency and power against a background of this wideband signal is presented. This method is based on nonheterodyne frequency and power conversion using a gyromagnetic converter that operates in two regimes: resonance detection and cross-multiplication. The wideband spectrum envelope of a random signal is visualized, and by switching two regimes and using correspondent filtration of the converted RF signal, the narrowband signals can be detected and measured. The block-scheme and operation of a two-channel measuring device combining …

Patent Scope And Innovation In The Software Industry, Julie E. Cohen, Mark A. Lemley

Georgetown Law Faculty Publications and Other Works

Software patents have received a great deal of attention in the academic literature. Unfortunately, most of that attention has been devoted to the problem of whether software is or should be patentable subject matter. With roughly eighty thousand software patents already issued, and the Federal Circuit endorsing patentability without qualification, those questions are for the history books. The more pressing questions now concern the scope to be accorded software patents. In this Article, we examine the implications of some traditional patent law doctrines for innovation in the software industry. We argue that patent law needs some refinement if it is …

Measurement And Monitoring Of Microwave Reflection And Transmission Properties Of Cement-Based Specimens, Sergey Kharkovsky, M. F. Akay, U. C. Hasar, C. D. Atis

Electrical and Computer Engineering Faculty Research & Creative Works

The results of measurement and monitoring of reflection and transmission properties of cement-based specimens (blocks of mortar, concrete) during long time of their service lives, including hydration process, and different curing conditions at microwave frequencies (X-band) are presented. A simple and inexpensive measurement system that utilizes the nondestructive and contactless free space method is used. Dependencies of the reflection and transmission coefficients on water-to-cement ratio, preparing and curing conditions of the specimens are demonstrated. It is shown that the reflection coefficient is approximately stable after hydration process while the transmission coefficient changes during long time of the specimen''s service life. …

Seeking Sunlight In Santa Fe's Shadow: The Sec's Pursuit Of Managerial Accountability, Donald C. Langevoort

Georgetown Law Faculty Publications and Other Works

My aim in this paper is not to justify at length an expansive "new corporation law" perspective, though I do believe in it. Nor do I want to try to resolve a controversial question that the new learning admittedly leaves open: which jurisdictional body should set the disclosure and antifraud standards insofar as they are designed to promote better corporate governance? To say that corporate and securities law are largely unitary does not necessarily mean that centralization of authority in the Securities and Exchange Commission (SEC or Commission) is the right choice. Perhaps the states, foreign countries, or stock exchanges …

Detection And Classification Of Impact-Induced Damage In Composite Plates Using Neural Networks, Rohit Dua, Steve Eugene Watkins, Donald C. Wunsch, K. Chandrashekhara, Farhad Akhavan

Electrical and Computer Engineering Faculty Research & Creative Works

Artificial neutral networks (ANN) can be used as an online health monitoring systems (involving damage assessment, fatigue monitoring and delamination detection) for composite structures owing to their inherent fast computing speeds, parallel processing and ability to learn and adapt to the experimental data. The amount of impact-induced strain on a composite structure can be found using strain sensors attached to composite structures. Prior work has shown that strain-based ANN can characterize impact energy on composite plates and that strain signatures can be associated with damage types and severity. This paper reports the extension of this approach for damage classification using …

Aha? Is Creativity Possible In Legal Problem Solving And Teachable In Legal Education?, Carrie Menkel-Meadow

Georgetown Law Faculty Publications and Other Works

This article continues and expands on my earlier project of seeking to describe how legal negotiation should be understood conceptually and undertaken behaviorally to produce better solutions to legal problems. As structured problem solving requires interests, needs and objectives identification, so too must creative solution seeking have its structure and elements in order to be effectively taught. Because research and teaching about creativity and how we think has expanded greatly since modern legal negotiation theory has been developed, it is now especially appropriate to examine how we might harness this new learning to how we might examine and teach legal …

What Courts Can Do In The Face Of The Never-Ending Asbestos Crisis, Paul F. Rothstein

Georgetown Law Faculty Publications and Other Works

The purpose of this article is not to argue that claimants suffering from serious asbestos-related diseases should not be compensated. To the contrary, one of the points of this article is that absent some change in the way asbestos claims are resolved, claimants who become truly sick in the future may not receive adequate compensation. Changing the current asbestos compensation system would be pro-claimant. Also, the purpose of this article is not to ascribe blame. Rather, it is to fix a problem. The judges cannot be blamed for their good intentions. Neither can the plaintiffs' attorneys be blamed for zealously …

Dynamic Resource Allocation For Network Echo Cancellation, T. Gansler, J. Benesty, M. Mohan Sondhi, Steven L. Grant

Electrical and Computer Engineering Faculty Research & Creative Works

Network echo canceler chips are designed to handle several channels simultaneously. With the processing speeds now available, a single chip might handle several hundred channels. In current implementations, however, the adaptation algorithm is designed for a single channel, and the computations are replicated N c times, where N c is the number of channels. With such an implementation, the computational requirement is N c times the peak load for a single channel. The number of computations required in each channel, however, varies widely over time. Therefore, a considerable reduction in computational load can be achieved by designing the system for …

The Federal Income-Contingent Repayment Option For Law Student Loans, Philip G. Schrag

Georgetown Law Faculty Publications and Other Works

Many idealistic law school graduates feel precluded from taking legal aid and other low-paying public service jobs because they have incurred high educational debt, often exceeding $100,000. In 1993, however, Congress created an "income-contingent" debt repayment option that was intended to enable high-debt, low-income graduates, including lawyers, to afford accepting public service positions. This program caps loan repayments at a reasonable percentage of the graduates' incomes, and it forgives any remaining balance at the end of twenty-five years. To date, this program has failed to meet the needs of public interest lawyers. It is rarely used. Law students are largely …

Experiments On Adaptive Techniques For Host-Based Intrusion Detection, Timothy Draelos, Michael Collins, David Duggan, Edward Thomas, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

This research explores four experiments of adaptive host-based intrusion detection (ID) techniques in an attempt to develop systems that can detect novel exploits. The technique considered to have the most potential is adaptive critic designs (ACDs) because of their utilization of reinforcement learning, which allows learning exploits that are difficult to pinpoint in sensor data. Preliminary results of ID using an ACD, an Elman recurrent neural network, and a statistical anomaly detection technique demonstrate an ability to learn to distinguish between clean and exploit data. We used the Solaris Basic Security Module (BSM) as a data source and performed considerable …

Factory Automation: A Controls Course For Every University, Kelvin T. Erickson

Electrical and Computer Engineering Faculty Research & Creative Works

The majority of new control engineering positions is now in manufacturing and involves programmable logic controllers (PLCs). The paper describes two courses developed at the University of Missouri-Rolla to satisfy this demand. Both courses present the subject of programming PLCs with an emphasis on the design of the programs. Both courses contain an integral laboratory component that solidifies the concepts presented in the lectures. The philosophy and pedagogical features of the two courses are first described, followed by the structure of the lecture and the laboratory exercises.

Collection Development In The New Millennium–Evaluating, Selecting, Annotating, Organizing For Ease Of Access, Reevaluating, And Updating Electronic Resources, Virginia A. Baldwin

University of Nebraska-Lincoln Libraries: Faculty Publications

The literature of the early 1990s suggested changes in the structure of collection management itself in order to accommodate the changes both now occurring and those foreseen. Sheila Creth wrote in 1991 "Until recently, the primary focus of collection development has been on building collections." She outlined the functions of collection management in academic libraries to include: selection of materials, weeding, preservation, liaison with faculty and academic departments, reference and user education, fiscal responsibility, and policy development. Creth saw the necessity for a basic change in the library’s organization structure. "According to the principles of organizational design, the traditional structure …

Learning Styles: Teaching Technology Subjects Can Be More Effective, Ronald I. Sutliff, Virginia A. Baldwin

University of Nebraska-Lincoln Libraries: Faculty Publications

Learning style theory has been developed and applied in various curricula for all levels of education. Kolb (1985) developed one particular method of assessing student learning style. The use of this method has been documented in the engineering and technology programs of several universities. Variations in learning style due to cultural diversity have been studied and are described in the literature.

This article describes and recommends the use of learning style theory to assess individual learning styles in the classroom and the use of teaching methods to accommodate various learning styles. Sutliff (one of the authors) administered the Learning Style …

Design And Implementation Of A Biologically Realistic Olfactory Cortex In Analog Vlsi, Jose C. Principe, Vitor G. Tavares, John G. Harris, Walter J. Freeman

Electrical and Computer Engineering Faculty Research & Creative Works

This paper reviews the problem of translating signals into symbols preserving maximally the information contained in the signal time structure. In this context, we motivate the use of nonconvergent dynamics for the signal to symbol translator. We then describe a biologically realistic model of the olfactory system proposed by Walter Freeman that has locally stable dynamics but is globally chaotic. We show how we can discretize Freemans model using digital signal processing techniques, providing an alternative to the more conventional Runge-Kutta integration. This analysis leads to a direct mixed signal {analog amplitude/discrete time) implementation of the dynamical building block that …

The first consideration prior to seeding is to determine the present level of management being applied to the proposed site. Many sites will recover or improve without seeding if proper management is implemented. Soil is the primary natural resource and its conservation is the most important consideration in seedings.

Frictions As A Constraint On Tax Planning, David M. Schizer

Faculty Scholarship

The government often uses narrow tax reforms to target specific planning strategies. Sometimes the targeted transaction is stopped. But in other cases, taxpayers press on, tweaking the deal just enough to sidestep the reform. The difference often lies in transaction costs, financial accounting, and other 'frictions, " which are constraints on tax planning external to the tax law.

This Article contributes a methodology for determining whether frictions will block end runs, and illustrates the effect of frictions by comparing the constructive sale rule of section 1259 with the constructive ownership rule of section 1260. These reforms use the same statutory …

Using A Neuro-Fuzzy-Genetic Data Mining Architecture To Determine A Marketing Strategy In A Charitable Organization's Donor Database, Korakot Hemsathapat, Cihan H. Dagli, David Lee Enke

Engineering Management and Systems Engineering Faculty Research & Creative Works

This paper describes the use of a neuro-fuzzy-genetic data mining architecture for finding hidden knowledge and modeling the data of the 1997 donation campaign of an American charitable organization. This data was used during the 1998 KDD Cup competition. In the architecture, all input variables are first preprocessed and all continuous variables are fuzzified. Principal component analysis (PCA) is then applied to reduce the dimensions of the input variables in finding combinations of variables, or factors, that describe major trends in the data. The reduced dimensions of the input variables are then used to train probabilistic neural networks (PNN) to …
