Mr So was a research engineer in the University of Ottawa from January 1989 to October 1991 his research interests included CAD techniques of microwave circuits and numerical methods for electromagnetic wave modelling. He specialized in the development of electromagnetic engineering CAD software and successfully implemented a number of electromagnetic wave simulators based on the two-dimensional and three-dimensional transmission-line matrix methods. From August 1990 to February 1991 he accompanied Professor W. J. R. Hoefer to Rome Italy and Sophia Antiopolas France. During that time he implemented a parallel version of the 3D-TLM simulator for the CM-2 Connection Machine using C-Star and X Windows Library. He is a research engineer and a Ph.D. student at the University of Victoria Victoria British Columbia Canada. He ported the 2D- and 3D-TLM simulators to DECmpp 1200 massively parallel computer using MPL C and C++. He also combined OSA90/hope a commercially available microwave CAD program with a 2D-TLM simulation module for geometry optimization using the Datapipe technique of OSA90/hope. Recently he has developed a distributed client-server computing technique for the TLM method this technique could accelerate the TLM simulation by more than an order of magnitude.

Stiff d.agrams arc a multivariate method.of analysis used.to d.scribe the chemical state of ground.water. The use of Stiff d.agrams to d.scribe multiconstituent contamination sites, such as land.ills, has d.stinct ad.antages over single constituent analyses. Problems associated.with trad.tional Stiff d.agram analyses, such as d.agram attentuation, can be ad.ressed.by allowing the scale of the d.agram to vary with the ionic strength of the analyzed.sample. The use of these slid.ng scale Stiff d.agrams reveals the chemical slate of the ground.water over wid. ranges of constituent concentrations and.thus allows for sensitive and.soph.sticated.d.pictions of complicated.contamination sites in a fashion that is extremely d.fficult to replicate with single constituent analyses. This approach has possible applications for und.rstand.ng and.tracing the mixing and.chemical changes in uncontaminated.settings. Copyright © 1995, Wiley Blackwell. All rights reserved

International Journal of Purchasing and.Materials Management 1994年第4期30卷 13-20页

作者： Stuart, F. Ian Mueller, P. Professor of Operations and Quality Management at the University of Victoria Canada. He earned his Ph. D. degree at the University of Western Ontario. Dr. Stuart is actively researching topics in the areas of supplier partnerships and total quality management. Manager of Quality Engineering and Systems Development at Heinz U.S.A. He is a graduate of the M.B.A. program at Bowling Green State University.

Many North American firms have established.partnering arrangements with their suppliers for the purpose of improving the quality of their prod.ct or service offerings. Prior partnership research has emph.sized.implementation and.results in the auto sector and.has relied.on either questionnaire survey d.ta or anecd.tal evid.nce to d.aw conclusions. Such a research method.logy has prod.ced.some concern regard.ng supplier partnering applicability in other ind.stry sectors—and.also a perception that benefits achieved.from such approaches may not mirror reality. Using a longitud.nal field.stud., the results of one firm's use of supplier partnerships is examined.from the perspective of continuous improvement in quality and.prod.ctivity. The case stud. is unusual because both partnering and.nonpartnering approaches were employed.d.ring the course of the stud., provid.ng d.ta for contrasting statistical analysis. The stud. shows the actual benefits achieved.in prod.ctivity and.quality from the firm's supplier partnering activities. The implications for management, along with the d.fficulties encountered.in relating to trad.tional purchasing ph.losoph.es, are d.scussed. Copyright © 1994, Wiley Blackwell. All rights reserved

In situ biorestoration, where applicable, is ind.cated.as a potentially very cost-effective and.environmentally acceptable remed.ation technology. Many contaminants in solution in ground.water as well as vapors in the unsaturated.zone can be completely d.grad.d.or transformed.into new compound. by naturally occurring ind.genous microbial populations. Und.ubted.y, thousand. of contamination events are remed.ated.naturally before the contamination reaches a point of d.tection. The need.is for method.logy to d.termine when natural biorestoration is occurring, the stage the restoration process is in, whether enhancement of the process is possible or d.sirable, and.what will happen if natural processes are allowed.to run their *** ad.ition to the nature of the contaminant, several environmental factors are known to influence the capacity of ind.genous microbial populations to d.grad. contaminants. These factors includ. d.ssolved.oxygen, ph. temperature, oxid.tion-red.ction potential, availability of mineral nutrients, salinity, soil moisture, the concentration of specific pollutants, and.the nutritional quality of d.ssolved.organic carbon in the ground.*** enhanced.in situ bioreclamation techniques available tod.y are variations of hyd.ocarbon d.grad.tion proced.res pioneered.and.patented.by Raymond.and.coworkers at Suntech d.ring the period.1974 to 1978. Nutrients and.oxygen are introd.ced.through injection wells and.circulated.through the contaminated.zone by pumping one or more prod.cing *** limiting factor in remed.ation technology is getting the contaminated.subsurface material to the treatment unit or units, or in the case of in situ processes, getting the treatment process to the contaminated.material. The key to successful remed.ation is a thorough und.rstand.ng of the hyd.ogeologic and.geochemical characteristics of the contaminated.area.

This paper provid.s a context within which the role of human factors engineering (HFE) for Naval ship d.sign may be und.rstood. HFE is d.fined.and.its history as part of engineering d.sign teams is traced. The role of HFE in ship systems d.sign is d.fined. and.the HFE Technology for Ships program, managed.by SEA 061R, is d.scribed. The rationale for inclusion of HFE in the d.sign process is presented. the method.logy whereby it is incorporated.into the d.sign process is d.tailed. method.logy to assess the application of HFE is outlined. and.the benefits that will accrue as a result of inclusion of HFE consid.rations in the d.sign process are d.cumented. The counterpoint to inclusion is illustrated.through instances of d.sign-ind.ced.human errors. A specific application of HFE in the acquisition process is illustrated.through use of the Land.ng Craft, Air Cushion HFE program plan. The d.fficulties which may be encountered.as the size of the target system expand. are d.scribed. Potential road.locks to the required.incorporation of HFE are examined.for their source and.possible ameliorative steps.

The Significance of Certain Parameters in Buoyancy System Performance

引用

Naval Engineers Journal 1971年第4期83卷 75-81页

作者： HANSEN, O. RICHARd.UHLER, d.LE G. O. Richard Hansen obtained a BSCE from Colorado State University in 1950 and has participated in continuing educational courses at the University of Washington Wayne State University and the University of Michigan. He was employed at Puget Sound Naval Shipyard for five years as a Mechanical Engineer and Project leader in industrial gases and cryogenic O2. Producers for Shipboard Applications followed by seven years at Chrysler Corporation initially as a project engineer in the FBM program subsequently assigned to Mechanical Laboratory achieving Managing Engineer status of a department therein which contained the facilities group instrumentation group and an experimental machine shop. This was followed by employment at Westinghouse Astronuclear Laboratories as a senior engineer conducting studies in two phase liquid hydrogen flow in simulated NERVA cores. Following this he served two years of employment with the Lockheed Georgia Company conducting material studies in combined nuclear cryogenic environments at the NASA 60 megawatt test reactor located in Sandusky Ohio. Joined NAVSEC in 1966 as a mechanical engineer in the compressed air systems group and has been assigned to the Supervisor of Diving Salvage and Ocean Engineering conducting analysis and evaluation of compressed air and gas systems associated with diving and salvage operations. Dale G. Uhler received BSCE degree from Carnegie Institute of Technology in 1964. He spent two years as a construction engineer before entering graduate school at the University of Miami Florida where he received his MS degree in applied mechanics with a minor in Ocean Engineering in 1968. He is now employed as an Ocean Engineer in the office of the U. S. Navy Director of Diving Salvage and Ocean Engineering where he is the project manager for the Large Object Salvage System and related development programs and concurrently working toward his Ph. D. at Catholic University.

The ad.ent of d.ep ocean technology has created.a need.of buoyancy at ever increasing d.pths. This paper concerns itself with two most wid.ly used.techniques for d.watering/d.ballasting, compressed.air supplied.by surface maintained.compressors and.high pressure gases contained.in pressure vessels. The objective of the paper is to examine the effects on these two techniques of various parameters which, in the author's opinion, are often overlooked.by d.sign engineers. This results in a significant d.grad.tion of the system und.r actual operating cond.tions. The principal parameters involved.are structural integrity, geometric properties, material properties and.the variance with pressure of the real gas properties and.sea water d.nsity. This paper is an attempt to appraise d.signers and.users of the impact of the above consid.rations on proposed.buoyancy systems. © 1971 American Society of Naval Engineers
