Innovative Applications Of Groupware For Solving Engineering Design Problems, Leslie F. Monplaisir, Colin Othniel Benjamin, Choayuan Lu

Engineering Management and Systems Engineering Faculty Research & Creative Works

In these case studies, groupware was used as a group decision-making environment to assist teams evaluating a quality function deployment framework for risk management and agile manufacturing system designs. In the first case, teams identified customers' requirements and risk categories for a research and development project. They then mapped the relationship between these customer requirements and the risk categories. In the second case, cross-functional teams collaborated in selecting the best layout for a cellular manufacturing facility. These experimental findings support the use of group decision systems by design and project teams required to manage R&D projects or to design agile …

Self-Assessment Of Total Quality Management Programs, Hung Yi Wu, Henry Allen Wiebe, John Politi Jan 1997

Self-Assessment Of Total Quality Management Programs, Hung Yi Wu, Henry Allen Wiebe, John Politi

Engineering Management and Systems Engineering Faculty Research & Creative Works

Total quality management (TQM) has been increasingly accepted as a management philosophy. Criteria such as those contained in the Malcolm Baldrige National Quality Award (MBNQA) often guide TQM implementation. However, reports indicate that fully assessing TQM efforts is difficult and hiring experts to help with this task is expensive. Using survey instruments is an attractive alternative to full-scale assessment. Despite the availability of many papers covering organizational performance assessment, few instruments specifically address TQM evaluation. Furthermore, none of the TQM assessment instruments has been subjected to rigorous validation; thus, only modest confidence can be placed in results obtained from their …

Asteroids And Comets: U.S. And International Law And The Lowest-Probability, Highest Consequence Risk, Michael B. Gerrard, Anna W. Barber Jan 1997

Asteroids And Comets: U.S. And International Law And The Lowest-Probability, Highest Consequence Risk, Michael B. Gerrard, Anna W. Barber

Faculty Scholarship

Asteroids and comets pose unique policy problems. They are the ultimate example of a low probability, high consequence event: no one in recorded human history is confirmed to have ever died from an asteroid or a comet, but the odds are that at some time in the next several centuries (and conceivably next year) an asteroid or a comet will cause mass localized destruction and that at some time in the coming half million years (and conceivably next year), an asteroid or a comet will kill several billion people. The sudden extinction of the dinosaurs, and most other species 65 …

Neutron Transmutation Doping As An Experimental Probe For Cuzn In Znse, Edward D. Wheeler, Jack L. Boone, J. W. Farmer, H. R. Chandrasekhar Jan 1997

Neutron Transmutation Doping As An Experimental Probe For Cuzn In Znse, Edward D. Wheeler, Jack L. Boone, J. W. Farmer, H. R. Chandrasekhar

Electrical and Computer Engineering Faculty Research & Creative Works

Nuclear transmutation is employed in an investigation of copper doping in ZnSe. Copper atoms are introduced at zinc sites in ZnSe after crystal growth processes are complete. Since the copper dopants are introduced after growth, far from equilibrium, they are less able to form complexes with other dopants or lattice defects as they may do when present during crystal growth. Initial results are consistent with CuZn being involved in the copper red and copper green emissions in ZnSe but not in the if exitonic emission. © 1997 American Institute of Physics.

An Analog Integrated Circuit For Continuous-Time Gain And Offset Calibration Of Sensor Arrays, Yu Ming Chiang, John G. Harris Jan 1997

An Analog Integrated Circuit For Continuous-Time Gain And Offset Calibration Of Sensor Arrays, Yu Ming Chiang, John G. Harris

Electrical and Computer Engineering Faculty Research & Creative Works

Parameter variations cause unavoidable nonuniformities in Infra-Red Focal Plane Arrays and other integrated sensors. Since these nonuniformities change slowly with time, calibrating sensors one-time only is not suitable-much more frequent calibration is required. We have developed an algorithm that continually calibrates an array of sensors that contain gain and offset variations. This algorithm has been mapped to analog hardware and designed and fabricated with a 2um CMOS technology. Measured results from the chip show that the system achieves invariance to gain and offset variations of the input signal.

Prediction Of Yarn Strength From Fiber Properties Using Fuzzy Artmap, Raonak Zaman, Donald C. Wunsch Jan 1997

Prediction Of Yarn Strength From Fiber Properties Using Fuzzy Artmap, Raonak Zaman, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

The count-strength-product (CSP) of cotton yarn is a complex function of fiber properties and spinning performance. The traditional way of predicting yarn CSP is using linear multiple regression. The correlation coefficient between actual CSP and predicted CSP obtained from linear regression is almost always less than 0.9. In this paper, we used a Fuzzy ARTMAP network to predict yarn CSP from fiber properties and spinning performance. Fiber properties and spinning data were used as inputs to ARTa, and yarn CSP was used as ARTb input. Our objectives are: better prediction of the quality of the end product, …

Stability Of Discrete-Time Matrix Polynomials, Khanh Tu Ngo, Kelvin T. Erickson Jan 1997

Stability Of Discrete-Time Matrix Polynomials, Khanh Tu Ngo, Kelvin T. Erickson

Electrical and Computer Engineering Faculty Research & Creative Works

This paper derives conditions for the stability of discrete-time systems that can be modeled by a vector difference equation, where the variables are m x 1 vectors and the coefficients are m x m matrices. Stability of the system is related to the locations of the roots of the determinant of a real m x m matrix polynomial of nth order. In this case, sufficient conditions for the system to be stable are derived. The conditions are imposed on the infinity norm of two matrices constructed from the coefficient matrices and do not require the computation of the determinant polynomial. …

The Supreme Court's Rejection Of Government Indemnification To Agent Orange Manufacturers In Hercules, Inc. V. United States: Distinguishing The Forest From The Trees?, Kacey Reed Jan 1997

The Supreme Court's Rejection Of Government Indemnification To Agent Orange Manufacturers In Hercules, Inc. V. United States: Distinguishing The Forest From The Trees?, Kacey Reed

University of Richmond Law Review

In recent years, the Supreme Court clarified the scope of immunity afforded to contractors for damages resulting from the performance of a government contract. However, the extent of the government's responsibility to indemnify third party claims resulting from a government contract has remained relatively obscure. Without clear direction, courts rejected government indemnification, relying upon a variety of detailed points of contract law which often concealed larger issues. In an appellate court dissent, Judge Plager criticized this result, warning that "undue attention to trees . . . often hides the forest."' Recently, in Hercules, Inc. v. United States, the Supreme Court …

A Law Professor’S Guide To Natural Law And Natural Rights, Randy E. Barnett Jan 1997

A Law Professor’S Guide To Natural Law And Natural Rights, Randy E. Barnett

Georgetown Law Faculty Publications and Other Works

Law professors nowadays mention natural law and natural rights on a regular basis, and not just in jurisprudence. Given that the founding generation universally subscribed to the idea of natural rights, this concept regularly makes a prominent appearance in discussions of constitutional law. One simply cannot avoid the concept if one is to explain Justice Samuel Chase's well-known claim in Calder v. Bull that "[t]here are certain vital principles in our free Republican governments, which will determine and over-rule an apparent and flagrant abuse of legislative power .... An ACf of the Legislature (for I cannot call it a law) …

Some Reflections On Copyright Management Systems And Laws Designed To Protect Them, Julie E. Cohen Jan 1997

Some Reflections On Copyright Management Systems And Laws Designed To Protect Them, Julie E. Cohen

Georgetown Law Faculty Publications and Other Works

Copyright management systems (CMS)—technologies that enable copyright owners to regulate reliably and charge automatically for access to digital works—are the wave of the very near future. The advent of digital networks, which make copying and distribution of digital content quick, easy, and undetectable, has provided the impetus for CMS research and development. CMS are premised on the concept of "trusted systems" or "secure digital envelopes" that protect copyrighted content and allow access and subsequent copying only to the extent authorized by the copyright owner. Software developers are testing prototype systems designed to detect, prevent, count, and levy precise charges for …

Adaptive Critic Design In Learning To Play Game Of Go, R. Zaman, Danil V. Prokhorov, Donald C. Wunsch Jan 1997

Adaptive Critic Design In Learning To Play Game Of Go, R. Zaman, Danil V. Prokhorov, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

This paper examines the performance of an HDP-type adaptive critic design (ACD) of the game Go. The game Go is an ideal problem domain for exploring machine learning; it has simple rules but requires complex strategies to play well. All current commercial Go programs are knowledge based implementations; they utilize input feature and pattern matching along with minimax type search techniques. But the extremely high branching factor puts a limit on their capabilities, and they are very weak compared to the relative strengths of other game programs like chess. In this paper, the Go-playing ACD consists of a critic network …

Hydro Unit Commitment In Hydro-Thermal Optimization, Chao-An Li, E. Hsu, Chung-Li Tseng, A. J. Svoboda, R. B. Johnson Jan 1997

Hydro Unit Commitment In Hydro-Thermal Optimization, Chao-An Li, E. Hsu, Chung-Li Tseng, A. J. Svoboda, R. B. Johnson

Engineering Management and Systems Engineering Faculty Research & Creative Works

In this paper, the authors develop a model and technique for solving the combined hydro and thermal unit commitment problem, taking into full account the hydro unit dynamic constraints in achieving overall economy of power system operation. The combined hydrothermal unit commitment problem is solved by a decomposition and coordination approach. Thermal unit commitment is solved using a conventional Lagrangian relaxation technique. The hydro system is divided into watersheds, which are further broken down into reservoirs. The watersheds are optimized by network flow programming (NFP). Priority-list-based dynamic programming is used to solve the hydro unit commitment (HUC) problem at the …

A Biologically Inspired Connectionist Architecture For Directing Attention To Salient Visual Field Objects, David Lee Enke Jan 1997

A Biologically Inspired Connectionist Architecture For Directing Attention To Salient Visual Field Objects, David Lee Enke

Engineering Management and Systems Engineering Faculty Research & Creative Works

In an attempt to incorporate basic visual attention abilities into existing artificial vision systems, a neural model of the bidirectional interactions within and between the brain regions believed to be involved in human visual attention has been developed. This model currently gives an artificial vision system the ability to attend to salient, or pop-out features and objects within the vision system''s field of view. After a review of the physiology of human visual attention, a network model of the aforementioned neural interactions is presented, followed by a demonstration of its performance.

An Object-Based Evolutionary Algorithm For Solving Rectangular Piece Nesting Problems, Kanchitpol Ratanapan, Cihan H. Dagli Jan 1997

An Object-Based Evolutionary Algorithm For Solving Rectangular Piece Nesting Problems, Kanchitpol Ratanapan, Cihan H. Dagli

Engineering Management and Systems Engineering Faculty Research & Creative Works

Nesting problems have been tackled by researchers using a vast number of algorithms in the past. Most of the algorithms, however, need to perform on a one-dimensional space. Therefore, the problem must be transformed into a one-dimensional space problem similar to the travelling salesman problem. Consequently, loss of solutions due to the dimensional reduction may occur. In this study, an object-based evolutionary algorithm for rectangular piece nesting problems is proposed. This methodology is created on truly two-dimensional space, allowing new mechanisms (i.e., individual representation, initialization, etc.) and new object-based genetic operators (i.e., hill-climbing, mutation, and recombination operators) to perform effectively …

Derivation Of Fuzzy Membership Functions Using One-Dimensional Self-Organizing Maps, Thomas E. Sandidge, Cihan H. Dagli Jan 1997

Derivation Of Fuzzy Membership Functions Using One-Dimensional Self-Organizing Maps, Thomas E. Sandidge, Cihan H. Dagli

Engineering Management and Systems Engineering Faculty Research & Creative Works

This paper discusses a system of self-organizing maps that approximate the fuzzy membership function for an arbitrary number of fuzzy classes. This is done through the ordering and clustering properties of one-dimensional self-organizing maps and iterative approximation of conditional probabilities of nodes in one map being the winner given that a node in the other map is the winner. Application of this system reduces fuzzy membership design time to that required to train the system of self-organizing maps.

Short-Term Resource Scheduling With Ramp Constraints [Power Generation Scheduling], Chung-Li Tseng, Chao-An Li, A. J. Svoboda, R. B. Johnson Jan 1997

Short-Term Resource Scheduling With Ramp Constraints [Power Generation Scheduling], Chung-Li Tseng, Chao-An Li, A. J. Svoboda, R. B. Johnson

Engineering Management and Systems Engineering Faculty Research & Creative Works

This paper describes a Lagrangian relaxation-based method to solve the short-term resource scheduling (STRS) problem with ramp constraints. Instead of discretizing the generation levels, the ramp rate constraints are relaxed with the system demand constraints using Lagrange multipliers. Three kinds of ramp constraints, startup, operating and shutdown ramp constraints are considered. The proposed method has been applied to solve the hydro-thermal generation scheduling problem at PG&E. An example alone with numerical results is also presented
