The objectives of Human engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine Technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.

An analytic model for the performance evaluation of space-division Asynchronous Transfer Mode (ATM) switches is presented. This model assumes that the switch has a fixed capacity of m, where 12 is given. The result shows that the performance of switches with a small capacity can approach that of output queueing. The model and result can be used for switch design analysis and higher layer performance models. © 1996 IEEE

Using computer assisted collaborative learning for high quality distance education

Describes a high-quality distance learning course in undergraduate signals and systems which is being taught at the University of Massachusetts, Dartmouth and is being shared with the University of Massachusetts, Boston. The course uses computer-assisted collaborative learning techniques over two-way compressed video. Students in this course spend most of their class time working in groups on problems or interactive demonstrations. Often, they use simulators with audio input and output. This gives students an active learning experience during the class while also sharply reducing the amount of information which must be sent in broadcast fashion through the video system. By using collaborative learning methods, the negative impact of the video system is greatly reduced in the classrooms at both ends. There are many logistical issues in designing a distance learning course using collaborative learning methods for a subject like linear systems. This paper describes the layout of a computer-assisted learning studio. It also discusses the teaching methods used. These were optimized together for maximum effectiveness of this distance learning course.

Investigations of Microwave Absorption in Insulating Dielectric Ionic Crystals Including the Role of Point Defects and Dislocations

引用

MRS Online Proceedings Library 1996年第1期430卷 397-402页

作者： Benjamin D.B. Klein Binshen Meng Samuel A. Freeman John H. Booske Reid F. Cooper Department of Electrical and Computer Engineering University of Wisconsin Madison USA Materials Science Program University of Wisconsin Madison USA Department of Materials Science and Engineering University of Wisconsin Madison USA

A theoretical model of microwave absorption in linear dielectric (non-ferroelectric) ionic crystals that takes into account the presence of point defects was synthesized and verified using NaCl single crystals. In the next stage of this research, we will introduce a controlled density of dislocations into the single crystal NaCl samples and study the effect on the microwave absorption mechanisms (ionic conduction, dielectric relaxation and multi-phonon processes) both theoretically and experimentally. Qualitative outlines of this modified theory are presented. The loss factor ε’ has been measured in the dislocation-free case by a cavity resonator insertion technique and the experimental results are in good agreement with the theoretical model. We describe the sample preparation technique that will be used to produce a controlled dislocation density in single crystal samples that will also be studied in our cavity resonator insertion system.

Statistical Comparative Analyses of engineering Properties of Microwave and Conventionally Sintered Alumina

引用

MRS Online Proceedings Library 1996年第1期430卷 453-458页

作者： K.R. Binger S.A. Freeman D.J. Grellinger R.F. Cooper J.H. Booske Department of Electrical and Computer Engineering University of Wisconsin - Madison Madison USA Material Science Program University of Wisconsin - Madison Madison USA Department of Material Science and Engineering University of Wisconsin - Madison Madison USA

Processing conditions such as temperature, soak time, and heating rate affect the final density of conventionally-sintered and microwave-sintered ceramics. Of additional importance is the question of whether microwave-sintered ceramics display intrinsically superior macroscopic engineering properties compared with conventionally-sintered control specimens. An analysis using the Yates algorithm indicates that the processing condition which has the largest impact on the density of the specimen is the heating method (microwave vs. conventional). The microwave-sintered specimens resulted in higher densities and higher fracture strengths. However, it was determined that the higher fracture strengths were due to the higher sintered densities rather than a significantly different microstructure.

IEEE National Conference on Aerospace and Electronics (NAECON)

作者： F. Rahman F. Ahmed M.A. Karim Department of Electrical & Computer Engineering Western Michigan University Kalamazoo MI USA Yept. of Electrical Engineering and Electro-Optics Program University of Dayton Dayton OH USA

Estimation of the distortion parameters in pattern recognition applications is addressed. This paper reports a new technique for the estimation of distortion parameters using correlation techniques with a synthetic joint Fourier transform (JFT) correlator set-up. In particular, the degree of rotational distortion is studied with the synthesis of a composite estimation feature from a set of distorted targets. Simulation results are presented to show better estimation performance.

Body surface Laplacian maps were studied from a set of unipolar potential data in healthy human subjects. The present results indicate that body surface Laplacian maps can be obtained with high reproducibility in the human subjects studied, and can reveal detailed information regarding the underlying ventricular conduction process.

Fusion power plants-goals and technological challenges

Fusion power plants-goals and technological challenges

引用

Intersociety Conference on Energy Conversion engineering (IECEC)

作者： F. Najmabadi Department of Electrical & Computer Engineering and Fusion Energy Research Program University of California San Diego La Jolla CA USA

Fusion is one of a few future power sources with the potential to be both economically acceptable and have attractive safety and environmental characteristics. In addition fusion fuel is inexhaustible, readily available, and affordable. Fusion can be an important option in the energy mix for the future because of environmental, supply, and political difficulties associated with fossil fuels and present-day nuclear power. An overview of the technological requirements for fusion power plants is given and their economic, safety, and environmental features are explored. Conceptual design studies predict that fusion power plants will be capital intensive and will be used as central electric power station. The cost of electricity from these power stations is estimated be comparable to other sources of energy. In addition, by using "low-activation" materials and care in design, fusion safety and environmental advantages (with respect to consequences of accidents, waste-disposal, and air pollution, etc.) can be realized. These advantages of fusion will not, however, be achieved automatically and a significant science and technology development program.will be required for their realization.
