International Conference on VLSI Design

作者： R. Nagalla G. Hellestrand Computer and System Technology Laboratory School of Computer Science and Engineering University of New South Wales Sydney Australia

In this paper we present a novel method to eliminate logic hazards, in particular dynamic hazards, in asynchronous circuits synthesized from the signal transition graph (STG) specifications. The existing hazard removal techniques work with the logic implementation derived from the STG specifications. This paper describes algorithms to detect and eliminate dynamic hazards without implementing the logic. Our algorithms have the advantage of directly operating on the STG specifications. In order to implement logic, an STG needs to satisfy the complete state coding (CSC) property. We first review a relationship between the causal relations of the signal transitions and the resultant logic (two-level sum-of-products or product-of-sums) implementations. Using this relationship, we identify the causes of dynamic hazards and remove the hazards by adding appropriate internal signal transitions to the STG.

Common geometric models for proteins and other molecules are the space filling diagram, the solvent accessible surface, and the molecular surface. We describe software that computes metric properties of these models, including volume and surface area. It also measures voids or empty space enclosed by the protein, and it keeps track of surface area contributions of individual atoms. The software is based on 3-dimensional alpha complexes and on inclusion-exclusion formulas with terms derived from the simplices in this complex. © 1995 IEEE.

This paper reports the application of evolutionary computation in the automatic generation of a neural network architecture. It is a usual practice to use trial and error to find a suitable neural network architecture. This is not only time consuming but may not generate an optimal solution for a given problem. The use of evolutionary computation is a step towards automation in architecture generation. In this paper a brief introduction to the field is given as well as an implementation of automatic neural network generation using genetic programming.< >

Interlaboratory reproducibility of an absorbed enzyme-linked immunosorbent assay (ELISA) kit for detection of bovine serum antibodies to Mycobacterium paratuberculosis was evaluated. A panel of 30 bovine sera (15 positives and 15 negatives) was tested in triplicate microtiter wells on each of 2 days at 8 different laboratories. One laboratory had invalid results because of positive or negative serum control optical density (OD) readings beyond the acceptable range specified by the kit. The coefficient of variation (CV) for mean OD values was influenced by low ODs on test negative sera at 2 laboratories, thus the CVs on positive sera were considered a more representative measure of kit reproducibility. Between-well CVs averaged 6.7% +/- 2.8% (mean +/- standard deviation), and between-day CVs averaged 14.5% +/- 9.8% among the 7 laboratories with valid assays on the 15 positive sera. The OD values were converted to positive or negative classifications for each assay well, and the results were compared. Among 1,392 assays in 7 laboratories, 98.6% were in agreement. Eleven of 18 discrepant results were due to a sample that consistently gave OD values near the cutoff for a positive test. Exclusion of that serum from the analysis resulted in a 99.8% rate of agreement among laboratories. Results indicated that the absorbed ELISA kit provided reproducible results within and between laboratories.

Immunophenotyping is widely used in immunology research as well as clinical diagnosis. Combinations of cluster designation (CD) markers are used to determine the stage of leukemia progression and arrive at a diagnosis. Implementing this process using relational databases with or without temporal extensions is extremely cumbersome. However, using an expert system environment such as the knowledge engineering environment (KEE) for implementing the immunophenotyping process, simplifies data management issues. An expert system model for immunophenotyping has been developed. The system uses CD marker values obtained from flow cytometric analysis in order to characterize cell maturation stages and thereby diagnose the disease state using known facts. This work discusses the implementation of the knowledge base and the diagnosis process involved in it.< >

A finger-shaped tactile sensor consisting of a charge-coupled device (CCD) and a semispherical optical waveguide covered with an elastic sheet and connected to a light source is proposed. The principle of the sensor is based on producing the scattering light at the sensor-object contact. The contact location is recognized using a CCD to detect light. By a simple calculation of the equation derived from the sensor surface geometry, the sensor can also provide the surface normal of the touched object. Through experiments using a prototype sensor, the fundamental characteristics of the sensor are evaluated and the principle of the sensor is confirmed.< >

This paper sets forth computer systems architecture concepts for the combat system of the 2010–2030 timeframe that satisfy the needs of the next generation of surface combatants. It builds upon the current Aegis computer systems architecture, expanding that architecture while preserving, and adhering to, the Aegis fundamental principle of thorough systems engineering, dedicated to maintaining a well integrated, highly reliable, and easily operable combat system. The implementation of these proposed computer systems concepts in a coherent architecture would support the future battle force capable combat system and allow the expansion necessary to accommodate evolutionary changes in both the threat environment and the technology then available to effectively counter that threat. Changes to the current Aegis computer architecture must be carefully and effectively managed such that the fleet will retain its combat readiness capability at all times. This paper describes a possible transition approach for evolving the current Aegis computer architecture to a general architecture for the future. The proposed computer systems architecture concepts encompass the use of combinations of physically distributed, microprocessor-based computers, collocated with the equipment they support or embedded within the equipment itself. They draw heavily on widely used and available industry standards, including instruction set architectures (ISAs), backplane busses, microprocessors, computer programming languages and development environments, and local area networks (LANs). In this proposal, LANs, based on fiber optics, will provide the interconnection to support system expandability, redundancy, and higher data throughput rates. A system of cross connected LANs will support a high level of combat system integration, spanning the major warfare areas, and will facilitate the coordination and development of a coherent multi-warfare tactical picture supporting the future combatant command st

GROUND WATER MONITORING AND REMEDIATION 1986年第4期6卷 49-55页

作者： SCHEINFELD, RA ROBERTSON, JB SCHWENDEMAN, TG Raymond A. Scheinfeld is a geologist with Roy F. Weston Inc. He holds a B. A. and an M. S. in geology from Temple University and is working on a Ph. D. in geology at the University of Delaware. His areas of specialization include organic and biogeochemistry sedimentology clay mineralogy karst hydrogeology aquifer testing and underground storage tank management. Todd G. Schwendeman is presently the underground storage system coordinator of the American Petroleum Institute. He has a B. S. in biology from Colgate University and an M. S. in civil engineering from Montana State University. From 1982 to 1983 he was employed by the Research and Technical Laboratory for Texaco USA. His responsibilities included ground water surface water and hazardous waste investigations and assessments. His experience includes chemical/soil science hydrogeology geology and ground water contamination computer modeling. Prior to working for Texaco Schwendeman was employed by the U. S. Forest Service to investigate the water quality impact of select dust suppressants as well as performing technical analyses for a soils engineering firm. John B. Robertson is vice president and director of National Ground Water Programs for Roy F. Weston Inc. Robertson holds a geological engineering degree from the Colorado School of Mines with advanced studies in ground water hydrogeology at the University of Arizona. Before joining Weston he served more than 20 years with the U. S. Geological Survey conducting research on the fate and behavior of organic and radioactive wastes in ground water ground water modeling and management of nationwide radioactive and hazardous waste hydrogeology programs. At Weston Robertson directs several underground storage tank technology projects ground water modeling studies and serves as senior technical advisor on major nuclear waste disposal programs remedial investigations and ground water protection programs.

A growing number of state and local governments and petroleum-related companies require the use of release detection systems for underground petroleum storage tanks. This has resulted in a confusing array of commercially available petroleum product detection devices, many of which have not been extensively field-tested. These systems, which are installed in ground water observation wells, vapor wells or U-tubes, include hydrocarbon-detecting paste, bailers, interface probes, electrical resistivity sensors, thermal-conductivity sensors, hydrocarbon-soluble devices, hydrocarbon-permeable materials and vapor detectors. This paper describes the available state-of-the-art technology for leak detection and the application for which each system is best suited.
