The development of real-time quality estimator schemes for emerging Internet videos with different content types remains a significant challenge and is crucial for the success of wireless multimedia systems. However, currently in-service assessment schemes fail in capturing subjective aspects of multimedia content related to the user perception. Therefore, this paper proposes an on-the-fly parametric video quality estimator approach (called MultiQoE) for real-time video streaming applications. Experiments in a Wireless Mesh Network (WMN) scenario were carried out to show the accuracy, benefit, and impact of MultiQoE compared to widely used Quality of Experience (QoE) subjective, objective and parametric methods.

This paper highlights the survivability concerns in the design of ship service power systems. The paper gives a brief description of what constitutes a typical ship service electric power system and concentrates on electric power generation and associated controls. Established survivability design principles and guidelines are highlighted and the application of those guidelines are discussed. General Specifications (Gen Specs) for Ships of the U.S. Navy are cited as the cornerstone for design. Specific design criteria are cited as well as the rationale associated with the survivability design guidelines pertaining to power generation and distribution. The application of these survivability design guidelines plus the use of the deactivation diagram/damage tolerance analysis cited in the Gen Spec section 072e will enhance overall design and help ensure survivable electric power systems for surface combatants.

Test and Evaluation have become paramount in today's Department of Defense acquisition process. Therefore, the U. S. Navy requires both private and public facilities to accomplish the final goals of the “Fly before Buy” concept. Such a facility exists at the Naval Coastal systems Laboratory (NCSL); an integral part of the Chief of Naval Material's, Director of Navy Laboratories organization. This paper briefly addresses the Laboratory, its mission, and its history. This is followed by an in—depth facilities overview in order to create an understanding of the slow but steady evolution of NCSL's unique fixed facilities. These facilities, when coupled to the local natural environment, provide a unique in situ test and evaluation capability which is unequalled in the United States for assessing seagoing coastal systems. Of prime consideration is the Range Date Acquisition Center (RADAC) and Its ancillary subsystems for tracking, environmental monitoring, communications, and post run analysis. The paper is concluded with a discussion of both past and present use of the aforementioned facilities with an emphasis on user acceptance and future potential growth.

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

ENERGY-CONSERVATION FOR PROPULSION OF NAVAL VESSELS

NAVAL ENGINEERS JOURNAL 1981年第2期93卷 131-144页

作者： BRADY, EF THE AUTHOR:: has varied experience in the Marine Nuclear Design and Computer Design fields. His background also includes three years as an Associate Professor of Engineering at Widener College Chester Pa. Educated at the U.S. Merchant Marine Academy Kings Point N. Y. he served four years in the U.S. Merchant Marine and presently holds an active U.S. Coast Guard License as a First Assistant Engineering Officer for steam Ships. After graduation he worked in the early design of Naval Nuclear Submarine Power Plants (Bettis Plant) during which time he completed his graduate studies at the University of Pittsburgh. While at the Westinghouse Bettis Plant he was involved in the Design and Development of the first S5 W Nuclear Propulsion Plant. This experience included investigation into the steam blanketing of heat transfer and his work was related to the phenomenon of “Chemical Hideout.” At the present time Dr. Brady is engaged in Advanced Technology Investigations for the Ingalls Shipbuilding Division of Lit ten Systems Inc. in Pascagoula Miss.

Energy conservation for powering of U.S. Surface Ships continues to be of prime importance in their design. Depletion by consumption of world petroleum reserves, combined with rapidly rising petroleum fuel costs, intensifies the need for improving the efficiency of current gas turbine power plants. Present gas turbine power plants, with a capacity adequate for naval ship propulsion, have a fuel consumption rate approaching 0.42 lbs. per brake horsepower hour at full power. Using a waste heat recovery unit, system studies show this can be reduced to less than 0.32 Ibs/BHP-HR. This 24% reduction in fuel consumption rate at full power or 35% at part power can produce either a corresponding increase in cruising range (for the same fuel loading), or a reduction in the required fuel loading and tankage (for the same cruising range). Therefore, to evaluate the merits of COGAS systems for U.S. NAVY Surface Ship propulsion, a study was made to evaluate their benefits. Ship impact studies and “trade-off” evaluations were completed. The results show that ultimate fuel consumption rates of 0.28 Ibs./BHP-HR at full power may be achieved, using large, efficient gas turbine units. This study also showed that, to obtain this fuel consumption improvement, this system required additional space and weight. Ship arrangements are also impacted. However, the effect on ship stability is slight. The net gain justifies the use of COGAS propulsion on future naval surface ships.

The structural design of a ship's section is a complicated, repetitive and time consuming task. With the advent of new technology, high speed computers have enabled the ship designer to accomplish in a matter of seconds what would formerly take days to accomplish by hand. The Structural Synthesis Design Program (SSDP) is a N avy developed computer-aided design tool which is used to design (or to analyze) the longitudinal scantlings for a variety of ship cross sections, consisting of any practical combinations of decks, platforms, bulkheads and materials, i.e., various steel and aluminum alloys. The final hull section design will have the lowest practical weight for the chosen geometric configuration, structural arrangements, and imposed loadings. The scantling developed by the program will satisfy all U.S. N avy ship structural design criteria. An explanation of the objective and design elements of N avy ship structures is included. The rationale behind the SSDP design philosophy is developed along with the significant program capabilities. In an attempt to highlight the influence of automated design procedures on the current naval ship design process, the effect of the SSDP on the DDG 51 destroyer structural development is addressed.
