He has served at the Philadelphia and Boston Naval Shipyards the headquarters of the Naval Sea Systems Command and its predecessor NAVSHIPS as staff officer to Commander Service Squadron Six in the Mediterranean in the USS Essex and with the Joint Military Assistance and Advisory Group Tehran. He is currently the director of Fleet Coordination Office at the Naval Ship Systems Engineering Station in Philadelphia.

The ship alteration (ShipAlt) process does not lend itself to the rapid accomplishment of small scale design changes to improve equipment performance and reliability. It is a necessarily lengthy and complex system, designed to deal with very large and costly projects. With one document, it causes replacement or modification of major ship systems. For this reason, ShipAlts are subjected to many reviews and design changes so that the final product will materially enhance the fleet's operational capabilities. The competition for scarce resources has left the Navy with a large number of needed design changes with no programmatic means to accomplish them. Various Navy communities have developed procedures to address this problem. This paper will show how the Naval Sea systems Command-sponsored machinery alteration (MachAlt) program addresses the small design change problem for hull, mechanical and electrical (HM&E) systems. MachAlts are design changes to equipments that do not require system interface changes and may be installed outside of industrial activities. The paper will discuss how the MachAlt concept was developed and will give a status report and assessment of the program to date.

NAVAL ENGINEERS JOURNAL 1984年第5期96卷 33-45页

作者： DETOLLA, JP FLEMING, JR Joseph DeTolla:is a ship systems engineer in the Ship Systems Engineering Division SEA 56D5 at the Naval Sea Systems Command. His career with the Navy started in 1965 at the Philadelphia Naval Shipyard Design Division. In 1971 he transferred to the Naval Ship Engineering Center. He has held positions as a fluid systems design engineer and auxiliary systems design integration engineer. Mr. DeTolla has worked extensively in the synthesis and analysis of total energy systems notably the design development of the FFG-7 class waste heat recovery system. He is NA VSEA's machinery group computer supported design project coordinator and is managing the development of a machinery systems data base load forecasting algorithms and design analysis computer programs. Mr. DeTolla has a bachelor of science degree in mechanical engineering from Drexel University and a master of engineering administration degree from George Washington University. He is a registered professional engineer in the District of Columbia and has written several technical papers on waste heat recovery and energy conservation. Jeffrey Fleming:is a senior project engineer in the Energy R&D Office at the David Taylor Naval Ship R&D Center. In his current position as group leader for the future fleet energy conservation portion of the Navy's energy R&D program he is responsible for the identification and development of advanced components and subsystems which will lead to reductions in the fossil fuel consumption of future ships. Over the past several years he has also directed the development and application of total energy computer analysis techniques for the assessment of conventional and advanced shipboard machinery concepts. Mr. Fleming is a 1971 graduate electrical engineer of Virginia Polytechnic Institute and received his MS in electrical engineering from Johns Hopkins University in 1975. Mr. Fleming has authored various technical publications and was the recipient of the Severn Technical Society's “Best Technical Paper of the Year” award in 1

In support of the Navy's efforts to improve the energy usage of future ships and thereby to reduce fleet operating costs, a large scale computer model has been developed by the David Taylor Naval Ship Research and Development Center (DTNSRDC) to analyze the performance of shipboard energy systems for applications other than nuclear or oil-fired steam propulsion plants. This paper discusses the applications and utility of this computer program as a performance analysis tool for design of ship machinery systems. The program is a simulation model that performs a complete thermodynamic analysis of a user-specified energy system. It offers considerable flexibility in analyzing a variety of propulsion, electrical, and auxiliary plant configurations through a component building block structure. Component subroutines that model the performance of shipboard equipment such as engines, boilers, generators, and compressors are available from the program library. Component subroutines are selected and linked in the program to model the desired machinery plant functional configurations. The operation of the defined shipboard energy system may then be simulated over a user-specified scenario of temperature, time, and load profiles. The program output furnishes information on component operating characteristics and fuel demands, which allows evaluation of the total system performance.

RATIONALE FOR AN ADA SOFTWARE engineering ENVIRONMENT FOR NAVY MISSION CRITICAL APPLICATIONS

引用

NAVAL ENGINEERS JOURNAL 1984年第4期96卷 133-145页

作者： PAIGE, KK CONVERSE, RA USN LCdr. Kathleen K. Paige USN:graduated with a BA from the University of New Hampshire in 1970. She received her commission from Officer Candidate School in April 1971 and performed her first tour of duty with VFP-63 NAS Miramar. LCdr. Paige then received her MS from the Naval Post Graduate School in June 1976 and returned to San Diego to serve as Head Support Software Division at the Fleet Combat Direction System Support Activity. In May 1981 she reported to NA VSEA (PMS-408) where she served initially as Chairman of the NAVMAT Software Engineering Environment Working Group. She has been assigned as Deputy AN/UYK-43 Acquisition Manager since October 1981. LCdr. Paige was designated a fully qualified Engineering Duty Officer in December 1983. Robert A. Converse:is presently the Acquisition Manager for the Ada Language System/Navy (ALS/N) for the Naval Sea Systems Command Tactical Embedded Computer Resources Project. As such he is responsible for the definition and development of the ALS/N to be provided as a Navy standard computer programming system for Navy mission critical applications. Mr. Converse received a Bachelor of Science degree in Physics from Wheaton College Wheaton II. He spent fourteen years with the Naval Underwater Systems Center Newport Rhode Island during which time he designed and developed the Fortran compiler for the Navy Standard AN/UYK-7 computer. Also during that period he received a Master of Science degree in Computer Science from the University of Rhode Island. His thesis for that degree was entitled “Optimization Techniques for the NUSC Fortran Cross-Compiler”. Mr. Converse started his involvement with the Ada program in 1975 with the initial “Strawman” requirements review. Subsequently he was named as the Navy Ada Distinguished Reviewer and was intimately involved in the selection and refinement of the Ada language as it evolved to become ANSI/MIL-STD-1815A.

The U.S. Navy introduced the use of digital computers in mission critical applications over a quarter of a century ago. Today, virtually every system in the current and planned Navy inventory makes extensive use of computer technology. Computers embedded in mission critical Navy systems are integral to our strategic and tactical defense capabilities. Thus, the military power of the U.S. Navy is inextricably tied to the use of programmable digital computers. The computer program is the essential element that embodies the system “intelligence”. In addition, it provides the flexibility to respond to changing threats and requirements. However, this very flexibility and capability poses a host of difficulties hindering full realization of the advantages. This paper describes the lessons learned about computer program development over the past twenty five years and discusses a software engineering process that addresses these lessons. It then describes how Ada and its related Ada Programming Support and Run-Time Environments foster this software engineering process to improve computer program productivity and achieve greater system reliability and adaptibility. Finally, the paper discusses how the use of Ada and its environments can enhance the interoperability and transferability of computer programs among Navy projects and significantly reduce overall life cycle costs for Navy mission critical computer programs.

He is a member of Tau Beta Pi the National Engineering Honor Society Pi Tau Sigma the National Mechanical Engineering Honor Fraternity and the ASME the American Society of Mechanical Engineers. Mr. Barnett has been a civilian employee of the Navy Department since 1967 and is currently employed as a navigation systems engineer at the Naval Air Development Center Warminster Pa. For the past nine years Mr. Barnett has specialized in and has been technically responsible for the development of ship and submarine speed sensors for U.S. Navy Fleet applications. Samuel H. Cheney:holds a Bachelor of Science in Electrical Engineering degree from Drexel University Philadelphia Pa. June 1974 where he specialized in electronics and communications. He is a member of the Institute of Electrical and Electronics Engineers (IEEE). Mr. Cheney is currently employed as an Electronics Engineer at the Naval Air Development Center (NAVAIRDEVCEN) Warminster Pa. where he is currently assigned as Project Engineer for the High Speed Velocity Log Program prior to coming to NAVAIRDEVCEN in September 1977 he was employed by the Department of the Army Frankford Arsenal where he was involved in development of electronic fire control systems.

Advanced high speed ships (surface effect ships, hydrofoils and air cushioned vehicles) under development will operate at speeds which are considerably higher than conventionally hulled ships. Precise velocity sensing and measuring techniques that provide the required accuracy throughout their operating speed range do not currently exist. This paper will discuss the Navy's development of a High Speed Velocity Log (HSVL), which will provide self contained, two-axis velocity measurement for these advanced high speed hulls. The system selected by the Navy for an exploratory development program uses microwave doppler radar technology. The paper will discuss reasons why an FM-CW doppler radar technique was chosen over other candidate technologies. The doppler radar technique involves the transmission of narrow beam radar signals down toward the water surface. Frequency of backscattered energy from the water surface is compared with the frequency of transmission to determine the “doppler” frequency shift from which ship's velocity relative to the water surface is computed. The paper will present test results of the HSVL feasibility model aboard the hydrofoil USS High Point (PCH-1) and aboard the Amphibious Assault Landing Craft Jeff (B). In addition, a summary of an intensive analysis phase to determine HSVL critical design parameters will be described.

Full-System (FS) simulation is essential for performance evaluation of complete systems that execute complex applications on a complete software stack consisting of an operating system and user applications. Nevertheless, they require careful fine-tuning against real hardware to obtain reliable performance statistics, which can become tedious, error-prone, and time-consuming with typical trial-and-error approaches. We propose a novel, streamlined, component-level calibration methodology to address these shortcomings to validate FS simulation models. Our methodology greatly accelerates the validation process without sacrificing accuracy. It is Instruction Set Architecture (ISA)-agnostic, and can tackle hardware specifications at different levels of detail. We demonstrate its effectiveness by validating FS models against both open-hardware and IP-protected (closed hardware) RISC-V silicon, achieving a mean error of 19-23% for the SPEC CPU2017 suite in the two cases. We introduce the first open-source RISC-V-based FS-validated simulation models with a complete and replicable methodology.

Mixed-Level Modeling and Evaluation of a Cache-less Grid of Processing Cells

ACM Transactions on embedded Computing systems 1000年

Modern processors experience memory contention when the speed of their computational units exceeds the rate at which new data is available to be processed. This phenomenon is well known as the memory wall and is a great challenge in computer engineering. The reason for this phenomenon is the unequal growth rate in memory access speeds compared to processor clock rates. In order to mitigate the memory bottleneck in classic computer architectures, a scalable parallel computing platform called the Grid of Processing Cells (GPC) has been proposed. To evaluate its effectiveness, the GPC is modeled at the instruction-level and functional-level using SystemC TLM-2.0, with a focus on memory contention. Individual GPC cells can be switched between the two abstraction levels. Our mixed-level system model enables fast and accurate simulations. We test multiple streaming applications on the GPC, analyze software-based optimization methods and their effects on the GPC, at both abstraction levels. The performance is then compared against the traditional shared memory processor (SMP) architecture. Experimental results show improved execution times on the GPC primarily due to a large decrease in main memory contention.
