system-on-Chip solid state circuits that sense, receive, transmit, and process signals are the sensors, or eyes and ears, of the medical field of the millennium. The goal and design of the system-on-Chip (SOC) program for industry will be to provide affordable, reproducible, and reliable front-end instrumentation, components and subsystems for medical systems. To process/store/analyze the signals acquired from these medical sensors, analog/digital systems are used to provide data fusion and information extraction. These biomedical smart sensors cover the hybrid domains of mixed-technology (electrical, mechanical, optical, thermal, biochemical) and mixed-concept (electrical, control, digital signal processing). These significant domain design differences impose robust design challenges for medical sensor technology.

The fast switching speed, snubberless turn-off capability and voltage controlled turn-off property enable the emitter turn-off (ETO) thyristor the capability of high switching frequency-about 5-10 times as high as its GTO counterpart. A one-megawatt ETO-based voltage source inverter system is constructed with a switching frequency up to 3-5 kHz. Experimental results have shown that the ETO is a promising device for use in high frequency systems.

C4ISR architectures: I. Developing a process for C4ISR architecture design

The C4ISR architecture Framework document issued by the Department of Defense specifies three views of an information architecture and defines a set of products that describe each view. These architecture views are to serve as the basis for C4ISR system development and acquisition. The Framework does not provide a process for architecture design. In this paper, information architectures are described in the context of Structured Analysis, and then the architecture views of the Framework and the related products are interpreted in that context. A methodology for architecture design is developed that is then implemented using Structured Analysis and object orientation in two companion papers. © 2000 John Wiley & Sons, Inc.

Switch scheduling in the multimedia router (MMR)

International Symposium on Parallel and Distributed Processing (IPDPS)

作者： D. Love S. Yalamanchili J. Duato M.B. Caminero F.J. Quiles School of Electricaland Computer Engineering Georgia Institute of Technology Atlanta GA USA Department of Information Systems and Computer Architecture Universidad Politecnica de Valencia Valencia Spain Department of Computer Science Escuela Politecnica Superior Universidad de Castilla La Mancha Albacete Spain

The primary goal of the Multimedia Router (MMR) project is the design and implementation of a router optimized for multimedia applications. The router is targeted for use in cluster and LAN interconnection networks which offer different constraints and therefore differing router solutions than WANs. This paper describes and evaluates a switch scheduling algorithm based on a priority biasing scheme for dynamically updating the priorities of the connections established through the router. Unlike existing schemes that simply use the age of a flit as its priority, the novel feature of the proposed approach is that the priority is biased using the measured quality of service (QoS) values for the connection. Furthermore, the structure of the switch scheduling algorithm is motivated by opportunities for pipelined and concurrent operation so that scheduling decisions could be made at switching speeds. The performance of two of the many possible biasing functions is evaluated.

A new integrated method is presented to recognize the emotional expressions of human using both voices and facial expressions. For voices, we use such prosodic parameters as pitch signals, energy, and their derivatives, which are trained by hidden Markov model for recognition. For facial expressions, we use feature parameters from thermal images in addition to visible images, which are trained by neural networks for recognition. The thermal images are observed by infrared ray which is not influenced by lighting conditions. The total recognition rates show better performance than that obtained from each single experiment. The results are compared with the recognition by human questionnaire.

Security assessment is to predict a power system's ability to withstand a set of next contingencies. An ANN-based pattern recognition method is used to perform static security assessment for power systems due to its potential in terms of speed and accuracy for online application. With the input pattern for ANN be composed of power system pre-contingency state described in busbar power injections (P, Q), the output pattern of ANN is composed of the performance index (PI) values of power system post-contingency state to a list of next contingencies. So the output vectors of ANN will indicate not only either 'secure' or 'insecure' state of the current system but also the severity of security limit violations under contingencies. To cope with the curse of dimensionality and improve efficiency of ANN, R-ReliefF algorithm is introduced to extract those variables that are with more discriminatory information from (P, Q) set to realise the nonlinear mapping from input space to output space. The proposed algorithm is tested on a 77-busbar practical power system with promising results.

Many discussions and articles address the business and military changes supporting implementation of Joint Vision 2010 and its system-of-systems approach. The dynamics of international military operations and commitments, coupled with accelerating information technologies, can lead to confusion and uncertainty Customary rules recommend caution, even stopping, when confusion and uncertainty are present, yet the needed changes counsel toward accelerated efforts. Currently, systems engineering does not completely address delivering "operational war fighting capabilities," or foster commanders' confidence to fully exploit those capabilities upon delivery. Acquisition reform supports accelerating delivery of systems. likewise, accelerated delivery of "war fighting capabilities" within any opponents' fielding and deployment cycle is imperative. Technical advances in modeling and simulation, utilization concepts, and innovative evaluation methods create an opportunity to facilitate codevelopment of doctrine, operations, and training prior to producing hardware systems. On-line simulation and evaluation tools can overcome the need for physical systems. Specifically, this paper lays out the opportunity to evolve systems engineering to another level, operational engineering, which leverages from the modeling and simulation environment, prior to hardware production. That modeling and simulation paired with coevolution of procedures and on-line analysis will produce a trained customer base, fully prepared for deliveries of "operational war fighting capabilities".
