INTEGRATION OF SHIP CONTROL-SYSTEMS FOR TOTAL SHIP SURVIVABILITY

NAVAL ENGINEERS JOURNAL 1992年第4期104卷 114-116页

作者： SIMPSON, HL FAMME, JB TAYLOR, B Joseph Famme:is the manager of marine systems CAE-Link Silver Spring Maryland. Mr. Famme joined Link in 1983 where he is responsible for developing marine products including digital control and monitoring systems for ships and submarines. Prior to joining Link then Commander Famme served in the U.S. Navy in all shipboard assignments including command of an FF-1052 class frigate. His engineering duties included supervising new construction sea trials and major mid-life ship overhauls. Mr. Famme has written concept papers defining architectures for future platform control systems and has worked within the simulation industry to introduce the use of distributed computer-based systems for training. He is currently working with various naval organizations and shipbuilding companies to develop the next generation of integrated digital control systems for ships and submarines. Barry Taylor:is the manager of marine systems at CAE Electronics Montreal Canada. CAE is currently supplying the integrated control systems for four classes of ships: the Canadian Patrol Frigate the DDH-280 the USN MHC-51 Minehunter and the SA'AR 5 corvette under construction at Litton - Ingalls Shipbuilding. Prior to joining CAE Electronics in 1987 then Commander Taylor served in the Canadian Navy as an engineering duty officer. His tours included sea duty as the engineering officer on five ships and shore duty assignments including one in the Directorate responsible for ship machinery control systems in the Canadian Navy. Commander Taylor was also the program manager for the Shipboard Integrated Machinery Control System Advanced Development Model (SHINMACS ADM). He has had numerous papers published on integrated ship control systems.

Effective damage control in naval ships has always been an important element of the naval combat equation. After receipt of battle damage, the ship's offensive operational capability depends upon its ability to support or restore vital systems. This in turn depends on the degree of initial damage, the damage control readiness condition of the ship, and effectiveness of the crew in applying the ship's damage control doctrine. In addition to conventional shell, mine, and torpedo threats, the speed and lethality of modern weapon systems presents an increased requirement for damage control readiness. New technology for the monitoring and control of the ship's hull, mechanical, electrical, and damage control (HME&DC) systems is now available with the potential for improving damage control readiness and for aiding the ship's commander in executing his damage control doctrine. This paper will describe the evolution of ship control systems, and discuss the application of current ship control systems technologies to damage control. It will recommend an optimum approach to meeting the requirements of damage control readiness posed by modern day threats, working within the U.S. Navy concept called Total Ship Survivability (TSS).

Induction machine drives with squirrel‐cage rotor will more and more replace the DC motor for its various advantages. The additional motor losses are essentially copper and iron losses in stator and rotor. Iron losses are significantly influenced by machine construction, magnetic materials used and supply type. Different formulae and estimations are given in the literature for these losses. In this contribution a method is presented for the calculation of additional iron losses in induction machines with PWM inverter. Two limits are deduced for the calculation of eddy‐current losses, within which the losses lie, and which agree with the theoretical basis and most empirical formulae given in the previous works. Similarly a new method is proposed for the additional hysteresis losses. The proposed methods give good results compared with the other known methods. Copyright © 1991 John Wiley & Sons, Ltd.

ADVANCED TECHNOLOGY IN NAVY LOGISTICS SUPPORT

引用

NAVAL ENGINEERS JOURNAL 1990年第3期102卷 111-118页

作者： HOUTS, RE The Author:is the director of the Advanced Logistics Technology Division in the Naval Supply Systems Command (NavSup) Engineering and Quality Directorate. He is responsible for managing Nav-Sup's lead role Navy-wide in the research and development of techniques processes and systems to improve Navy readiness and productivity. In this role his office serves as the Navy's Computer-aided Acquisition and Logistics Support (CALS) primary support office. Mr. Houts has more than 19 years of government service as a career logistics manager including a year-long assignment in OSD. Prior to being selected for the senior executive service in December 1985 and accepting his current position Mr. Houts spent 15 years at the Naval Air System Command. He has had extensive experience in logistics program initiation on major aircraft systems and in the development of contractual documents to implement logistics programs. He holds a B.S. degree in aerospace engineering from the University of Michigan and an M.S. degree in systems management from the University of Southern California.

In the face of present and foreseeable budget constraints which will severely restrict the amount of funding available to provide logistics support to the Navy's operating forces, the Naval Supply Systems Command's Advanced Logistics Technology Division is actively pursuing a number of efforts to apply current and emerging technology to improve logistics systems and methodologies. The engineering Data Management Information and Control System (EDMICS) Program will automate the technical information process from initial acquisition through delivery to the end user, addressing the inability of current paper-based systems to cope with the tidal wave of information requirements for the effective management of weapon and logistics systems. Rapid Acquisition of Manufactured Parts (RAMP) Program is applying computer integrated manufacturing (CIM) technology to the production of spare parts which are normally available only at great cost and with extensive lead time. The Standard Hardware Acquisition and Reliability Program (SHARP) will standardize electronic system hardware (i.e., modules, power supplies, enclosures and batteries) to decrease development and logistics costs, while providing dramatic increases in component and system reliability. The Integrated Diagnostic Support System (IDSS) project is integrating diagnostic design into the weapon system development process to enhance the ability of the organizational level technician to detect and isolate system/equipment failures. This paper discusses each of these ongoing projects as well as a number of new initiatives being explored for future funding.

STANDARD HARDWARE ACQUISITION AND RELIABILITY PROGRAM - CONCEPTS, BENEFITS, AND POTENTIAL

引用

NAVAL ENGINEERS JOURNAL 1989年第3期101卷 231-239页

作者： WEAVER, LW The author:is a program manager with Naval Weapons Support Center Crane Indiana. Mr. Weaver graduated from Indiana State University in 1969 where he received a B.S. degree with a mathematics major and a minor in physics. He began his career with the Naval Weapons Support Center in 1969 where he worked as a physicist and as an electronics engineer before entering various management positions. In the past ten years he has provided engineering and technical support to fleet ballistic missile guidance programs and to Navy standard computer and standard signal processor programs. He recently completed an assignment as manager of an electronics systems development division with responsibility for development of electronic control systems for fleet applications using standard electronic modules. Currently he is the program manager for the Standard Hardware Acquisition and Reliability Program (SHARP) managed through the Naval Sea Systems Command Sea-06. He is a member of the American Society of Naval Engineers and the Federal Managers Association.

The Standard Hardware Acquisition and Reliability Program (SHARP) includes three major categories of hardware standards. They are Standard Electronic Modules (SEM), Standard Power Supplies (SPS), and Standard Electronic Enclosures (SES). SHARP responsibilities include development and testing of these standards and their integration into electronic systems. The purpose of SHARP is to reduce development, production, and logistics support costs of electronic systems; to improve system operational availability; and to shorten the system acquisition cycle. The basic concepts applied towards this purpose are: functional standardization; functional specification; a disciplined quality program; design flexibility; and emphasis on design for maintenance and repair. The paper describes the application of these concepts in the SHARP program and how they result in: — improved performance and supportability; — multisystem application of functional standards: — standard interfaces between system elements; — competitive procurement of hardware; — improved system readiness; — interchangeability of spares; — introduction of new technology into deployed systems; — improved testability; and — reduced cost to the Department of Defense (DoD). SHARP experience and benefits to the user are described, including specific applications of SHARP hardware in DoD systems and examples of multimillion dollar cost savings to these systems. The status of current SHARP initiatives and potential savings through broader application of SHARP in system developments are then discussed.

NAVAL ENGINEERS JOURNAL 1988年第4期100卷 191-199页

作者： KAYE, AR STARCHUK, GJ A. Roger Kaye:is a professor in the Department of Systems and Computer Engineering at Carleton University Ottawa Canada. His research interests are in computer-communication networks and expert systems for their management. He spent many years in both industrial and government research laboratories prior to joining Carleton. He holds the Ph.D. and M.Eng. degrees from Carleton and the B.Sc. (Eng.) from the University of London England. Gary J. Starchuk:received the B.Eng. degree in engineering management at the Royal Military College of Canada in 1973 the M.A.Sc. degree in management sciences from the University of Waterloo in 1979 and the M.Sc. degree in information and system science from Carleton University in 1987. He holds the rank of lieutenant commander in the Canadian Forces and is currently serving as a project manager in a major project.

The paper presents performance results for the SHINPADS serial data bus operating in the environment of a modern, frigate-class ship using a combination of point-to-point links for certain major applications systems and the shared, SHINPADS bus for others. The traffic model used is representative of experience in the design of new ships of this type. It is shown that the bus has adequate performance for the expected traffic load. In addition it is shown that, as traffic increases, delay problems will show up in the application processor environment before there is any significant degradation of the performance of the bus. The value of the provision of several classes of priority on the bus is also investigated.

NAVAL engineering ANALYSIS

引用

NAVAL ENGINEERS JOURNAL 1988年第3期100卷 306-316页

作者： PACE, DK HUNT, RJ Dale K. Pace:is a member of the Principal Professional Staff of The Johns Hopkins University Applied Physics Laboratory (APL). He currently serves as the APL liaison with the Hopkins School of Advanced International Studies and with the Naval War College. His professional responsibilities have included various leadership roles in the Military Operations Research Society chairmanship of the Physical and Engineering Sciences Group for the Summer Computer Simulation Conference and chairmanship of the ASNEJournalCommittee. Richard J. Hunt:is head of the Naval Warfare Analysis Department of The Johns Hopkins University Applied Physics Laboratory (APL). A graduate of the Loyola College in Baltimore (B.S. in mathematics) in the 1950s Mr. Hunt was involved with development and use of the first digital computer simulation of Navy AAW. Since then he has played major roles in all aspects of analyses of surface ship AAW and of many other naval warfare topics. Currently he is a member of the FOSAD the Federation of Systems Analysis Directors for Navy R&D Centers and APL.

Analysis pervades all aspects of naval engineering. It is used to determine requirements for new or upgraded systems and to explore concepts for their employment. It is used to evaluate performance. It is used to establish design characteristics. And it comes in many varieties. This paper addresses use and misuse of analysis in naval engineering. The paper is oriented toward managers of analytic endeavors rather than the practitioners of analysis. It does not deal in depth with how to perform particular analytic techniques. Instead it discusses general principles that should guide both the selection and application of analytic techniques. The paper identifies problems which are frequently encountered in analyses related to naval engineering and suggests ways to ameliorate their deleterious effects. These problems are addressed from both the perspective of the manager of analysis and that of the user or consumer of results from the analysis. Some of the challenges that face naval engineering analyses as a consequence of hardware and software improvements and of more sophisticated systems are also discussed.

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.

GROUND WATER MONITORING AND REMEDIATION 1986年第2期6卷 92-98页

作者： KENNEDY, KG HOLLINGSHEAD, SC LEECH, REJ Keith G. Kennedy (Gartnet Lee Associates Ltd. Toronto-ButtonuilleAirport Markham Ontario L3P3J9 Canada) has been working in the earth sciences petroleum and environmental fields since 1967. He received his B.Sc. (geology)from the University of Manitoba in 1971 and his M.Sc. (hydrogeology) from the University of Waterloo in 1974. He began working in the consulting business in 1973. He has workedprincipally withfour major consulting companies since that time on projects in Canada the United States Europe and the MiddleEast. His specialties are in the areas ofwell test interpretation hazardous waste disposal technology and flow systems analysis. Stephen C. Hollingshead received his BA.Sc. in geologicgl engineerirtg from the Unioersity of Toronto. He subsequently attended Queen's University in Kingston Ontario where he completed his M.Sc. (English) in engineering geology. His master's thesis was directed by Gurtner Lee Associates Ltd. and involved the use of computer modeling to evaluate the hydrogeology performance of landfills. Since his graduation he has joined Gartner Lee as an engineering geologist and has continued to work on the application of hydrogeologic modeling to practical problems. Robert E.J. Leech has 15 years of experience in hydrogeological investigations. He received his B.Sc. (Hons) in geology and chemistry from the University of Aston U.K. and his M. Eng. SC. in hydrogeology from the University of New South Wales Australia. He spent nine years working for the Geological Survey of Western Australia mainly in the area of ground water resources evaluation in arid and semiarid ctimates. Since moving to Canada in 1979 he has worked on numerous hydrogeological studies related to hazardous and radioactive waste. Leech is currently a principal with Gartner Lee Associates Ltd. and is responsible for their work in deep well testing andformation evaluation.

There has been increased interest in low transmissivity formations as barriers to, and hosts for, different hazardous waste. Long periods of time are generally required to measure their in situ pressures or hydraulic heads. Sites need extensive instrumentation and monitoring schemes, which may be costly and may require long periods of time prior to providing well documented site-specific data. A method has been developed that allows pressure and head distribution to be determined based on limited formation testing. This distribution can then be used to refine the final design of the borehole monitoring instrumentation. Recent work on shallow and deep, hazardous and nuclear waste disposal studies in Canada and Europe has provided the opportunity to investigate different methods for extrapolating and estimating the distribution of pressure and equivalent hydraulic head of the pore water in tight formations. The result is an approach that is cost-effective, technically reasonable and relatively rapid. The technical basis of the method is not new. However, its application to determining profiles of either formation pressure or hydraulic head has not been well documented. This approach has potential for use in many site investigation studies. The method determines the profile of head or pressure between two “input” layers or formations, which have been well characterized with respect to their pressures or hydraulic heads and associated fluid characteristics. The pressure profile between the two layers is a function principally of the transmissivity of the tight formations between the input layers. Therefore, the primary objective of testing of the zones between the two input layers is designed to quantify this parameter. This testing can be relatively rapid compared to the time required to measure a representative formation pressure or water level. The technique is computerized for efficient tabulation and graphical data display. This paper presents the rationale associa

What should a computer‐literate physician know?. How should he or she come to know it?

引用

Möbius: A Journal for Continuing Education Professionals in Health Sciences 1983年第4期3卷 43-52页

作者： Tuttle, Mark S. Mark S. Tuttle M.D.:Mark S. Tuttle is a lecturer in the Computer Science Division of the Dept. of Electrical Engineering and Computer Sciences at the University of California Berkeley and in the Section on Medical Information Science at the University of California San Francisco. His major research interest is in the process of inference especially medical inference. He is also at work on an introductory computer scence text devoted to conceptual foundations.

In spite of the rapid growth and evolution of information technology, it is possible to identify certain core skills, concepts, and powerful ideas that physicians should possess if each of them is to answer, competently and on a continuing basis, the question, “Where, if at all, should information technology be used in my professional activities?” It is argued that these skills and many of the concepts should be acquired experientially (by using computers), that the powerful ideas can be appreciated with time, and that much of this knowledge, particularly that relating to the nature and limits of “symbolization,” will defy rapid obsolescence. For many physicians, the most straight‐forward path to computer literacy begins with exploratory use of a personal computer.
