Aizu International Symposium on Parallel Algorithms/Architecture Synthesis

作者： Jung-Sing Jwo Shi-Sen Chang Yi-Cheng Chen D.F. Hsu Department of Computer and Information Sciences Tunghai University Taichung Taiwan Graduate Program in Computer Science Fordham University New York NY USA

Proposes a distributed computing environment, called the Virtual Cube (VC), to support arbitrarily large binary hypercube computing on a cluster of homogeneous workstations that are interconnected by an Ethernet LAN. The embedding concept between binary hypercube parallel architectures is introduced, and the concept of a cluster of computers interconnected through a computer network. In VC, a SIMD parallel language called VCPL (VC Parallel Language) is provided. The advantages of the VC system are that (a) it can be considered as a practical and economical binary hypercube machine, and (b) it brings parallel solutions on a binary hypercube directly into distributed applications. Currently, a VC prototype is implemented on NeXT workstations.

A jamming game is considered. A transmitter encodes the data, in a product code (PC), and transmits it in a slow frequency-hopped spread-spectrum (FHSS) system. A hostile jammer attempts to block correct packet reception by adjusting the fraction of the total band in which it distributes the jam power, /spl rho/. Two cases are considered. In the first case, the transmitter declares his strategy and the jammer uses this information to select his best jamming fraction. In the second case, the jammer declares his strategy first and the transmitter uses this information to select his best rates. Results are obtained using asymptotic analysis of a product code using singly extended Reed-Solomon (RS) row and column codes whose size grows large. This asymptotic analysis leads to good choices of the row and column rates for the PC in both cases.

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.

This paper is a case study of how problem resolution can operate in the life cycle maintenance stage of a large tactical sonar system. Here, the system design agent is not the original designer, so the principles of operation, hardware and software architecture, and test tools need to be learned. To deal with this challenge, the system design agent evolved a team approach that integrates the talents of a program manager, a system engineer, a test engineer, and a software engineer to analyze fleet problems. This team has proven effective at localizing problems for repair. Lessons are drawn to further improve maintenance efficiency.

PERMUTATION ROUTING AND SORTING ON MESHES WITH ROW AND COLUMN BUSES

引用

Parallel Processing Letters 1995年第1期5卷 63-80页

作者： TORSTEN SUEL Department of Computer Science University of Texas at Austin Austin TX 78712 USA Supported by the Texas Advanced Research Program under Grant Nos. #003658–480 and #003658–461 and by a Schlumberger Graduate Fellowship.

We study the problems of permutation routing and sorting on several models of meshes with fixed and reconfigurable row and column buses. We describe two fast and fairly simple deterministic algorithms for permutation routing on two-dimensional networks, and a more complicated algorithm for multi-dimensional networks. The algorithms are obtained by converting two known off-line routing schemes into deterministic routing algorithms, and they can be implemented on a variety of different models of meshes with buses. We also give a deterministic algorithm for 1–1 sorting whose running time matches that for permutation routing, and another algorithm that matches the bisection lower bound on reconfigurable networks of arbitrary constant dimension.

Mr. Hall is a member of the American Institute of Physics and Sigma Pi Sigma (National Physics Honor Society).

A growing concern about the shrinking size of the U.S. Navy budget and the pool from which selections will be made to ''man'' U. S. Navy shipboard systems has led to investigations on achieving improvements in affordability and operational effectiveness. One such investigation has resulted in the development of the Standard Monitoring and Control System (SMCS), a modular, open architecture control system which includes the control system components for propulsion, electric plant, auxiliaries, and damage control. The first major technology upgrade to SMCS will entail the insertion of Artificial Intelligence (AI) technologies into HM&E monitoring and control applications. The Intelligent Machinery Control Integration Task (IMCI) was established to provide a structural approach for this major technology upgrade. As part of the first phase of IMCI, an identification of intelligent control requirements, an assessment of AI technologies, and a survey of intelligent control applications were performed. This paper lists those HM&E-related shipboard operational requirements from which intelligent machinery control requirements will be identified. Also, there is an initial assessment of AI-related reasoning and the following AI technologies, knowledge-based systems, fuzzy logic, neural nets, and genetic algorithms. The survey provided some insight into applying AI technologies to SMCS shipboard operational requirements.

Synthetic Ethology and the Evolution of Cooperative Communication

引用

Adaptive Behavior 1993年第2期2卷 161-188页

作者： Maclennan, Bruce J. Burghardt, Gordon M. Computer Science Department University of Tennessee Knoxville TN 37996 United States Psychology Department and Graduate Program in Ethology University of Tennessee Knoxville TN 37996 United States

Synthetic ethology is proposed as a means of conducting controlled experiments investigating the mechanisms and evolution of communication. After a discussion of the goals and methods of synthetic ethology, two series of experiments are described based on at least 5000 breeding cycles. The first demonstrates the evolution of cooperative communication in a population of simple machines. The average fitness of the population and the organization of its use of signals are compared under three conditions: communication suppressed, communication permitted, and communication permitted in the presence of learning. Where communication is permitted, the fitness increases approximately 26 times faster than when communication is suppressed;with communication and learning, the rate of fitness increase is nearly 100-fold The second series of experiments illustrates the evolution of a syntactically simple language, in which a pair of signals is required for effective communication. © 1993, Sage Publications.

UNDERWATER INSPECTION FOR WELDING AND OVERHAUL

引用

NAVAL ENGINEERS JOURNAL 1993年第5期105卷 37-42页

作者： MITTLEMAN, J SWAN, L John Mittleman:is a mechanical engineer at the Naval Surface Warfare Center Dahlgren Division Coastal Systems Station in Panama City Florida. His Primary Responsibilities are in the development of underwater nondestructive testing equipment for use by fleet divers and inspectors. He also performs research in the characterization of metal microstructure through ultrasonic scattering measurements. Mr. Mittleman received his BS from Cornell University in 1969 and science master's in ocean engineering from the Massachusetts Institute of Technology in 1970. His research currently supports doctoral studies with Iowa State University. Mr. Mittleman received the American Society of Naval Engineer's Solberg Award in 1981 for his contributions to underwater ship hull inspection. Mr. Mittleman is a member of ASNE ASNT ASTM IoD Sigma Xi Tau Beta Pi and Phi Kappa Phi. Lisa Swan:is a mechanical engineer at the Naval Surface Warfare Center in Panama City Florida. She is involved in nondestructive testing engineering primarily in the underwater arena. Ms. Swan holds a bachelor of science in materials engineering from North Carolina State University. She is a graduate of the Federal Women's Executive Leadership Program. Ms. Swan is a member of ASNT.

Significant progress has been made in making underwater ultrasonic thickness gauging and magnetic particle inspections available to the fleet. Under sponsorship from the Naval Sea Systems Command, Director of Ocean Engineering, Underwater Ship Husbandry Division (NavSea 00C5), the Coastal Systems Station has developed complete hardware packages supporting these two nondestructive test methods, and has introduced them to military inspectors at a shore intermediate maintenance activity, a destroyer tender, and a naval shipyard. Performance trials conducted prior to taking the systems to the field have been accepted by NavSea, Ships' Concepts Group, Materials Subgroup, Metals Division (NavSea 5142) as evidence that these inspections can reliably be performed underwater. Avenues for certifying specially trained divers and inspectors are being developed;for the first time the Navy will have all of the elements in place for underwater inspections satisfying the requirements of Mil-Std-271 (Requirements for Nondestructive Testing Methods) and the Naval Ships' Technical Manual Chapter 074. Underwater ultrasonic thickness gauging has also been slated for use in the fleet, as data from laboratory and field trials have consistently shown that reliable results can be obtained by a team comprising a certified topside inspector and a diver. In tests performed at the Ship Repair Facility (SRF), Yokosuka, underwater readings were compared to those taken in dry dock by SRF inspectors, and independently by contract inspectors. On the basis of approximately 800 locations, differences between the data sets were found to be randomly distributed, with a standard deviation on the order of 0.02''. This level of accuracy is largely sufficient to distinguish plate which will need replacement during overhaul, or plate which is thick enough to weld on.
