Transporting video data thought a Wireless Sensor Network is inherently vulnerable to attacks due to the open nature of the physical media. To protect the authenticity of the received video data, we present a scheme that incorporates a blind video watermarking method and middleman detection algorithms to defend against correlation and middleman attacks. We uses a unique F-modulation method where each watermark bit is modulated by a local F bit to enable blind detection at the receiver side. A novel content based block selection algorithm is used to spreading the locations of marked blocks to prevent correlation attack. Copyright © 2010 Inderscience Enterprises Ltd.

READINESS BASED SPARING - IMPROVED READINESS AT REDUCED COST

引用

NAVAL ENGINEERS JOURNAL 1990年第2期102卷 43-50页

作者： BURDICK, L THE AUTHOR:: is the assistant deputy commander for fleet support corporate plans and logistics of the Naval Supply Systems Command Headquarters. Mr. Burdick has fifteen years of U.S. Navy supply and logistics experience. In addition to his current position he has been the deputy director for integrated logistics support and an operations research analyst in NavSupSys-ComHQ. Before his service in Washington D.C. he was an operations research analyst at the Fleet Material Support Office in Mechanicsburg Pa. Mr. Burdick's background includes ten years experience in readiness based sparing and twelve years experience in inventory policy and requirements model development. He chaired the Navy Working Group that implemented the Modified Fleet Logistics Support Inventory Program (MOD-FLSIP) which includes development of the OSD approved criteria for assignment of mission criticality codes (MCCs) to weapon systems on deployed ships. Mr. Burdick is currently cochairing a joint NavSea/NavSup working group that is prototyping the sparing of the entire DDG-52. Mr. Burdick received his M.A. in mathematics from the State University of New York at Stony Brook and his B.A. in mathematics from the State University of New York College at Potsdam. In addition he received a professional degree in operations research with a minor in engineering administration at George Washington University.

Since Fiscal Year 1979, Congress has required thai Defense Department budgets provide the relationship between resources and readiness. This required that the Navy establish a measure of material readiness. Operational availability, or Ao, became the measure of material readiness in 1981. In March of 1981, CNO approved the Availability Centered Inventory Model (ACIM) as the Navy spares optimization model for use in shipboard weapon systems and equipment applications. The early 1980s terminology of Sparing to Availability is currently termed Readiness Based Sparing. CNO mandated in August 1986, the universal application of readiness based sparing techniques to all nonnuclear ACAT I, II and III acquisition programs. RBS is not just a model into which data is input and an allowance of spare parts is printed out. RBS is a process that requires consistent and continuous integration and correlation of spares data to total system data, operating parameters and requirements. support requirements must be determined in conjunction with the total weapon system, and material readiness, measure of effectiveness and performance should be assessed against that same measure. Traditional measures of supply system effectiveness are only partial input data to the ultimate requirement of weapon system material readiness. The Readiness Based Sparing Process is a disciplined integration of design, configuration management, maintenance, and logistics support. RBS is system specific. Therefore, all data that is input to an RBS model must be system application specific. Today's data collection systems, and consequently the budget and execution processes, are not oriented to specific weapon system management. Consequently, the current and ongoing agenda in the implementation and institutionalization of Readiness Based Sparing - The Process, is directed towards the integration of logistics data bases, and the data within those data bases, to a weapon system management orientation.

SHIP DESIGN AND THE NAVY LABORATORY

NAVAL ENGINEERS JOURNAL 1981年第2期93卷 33-46页

作者： ELLSWORTH, WM CLARK, DJ Mr. William M. Ellsworth:is graduate of the State University of Iowa from which he received B.S. and M.S. degrees in Engineering majoring in Fluid Mechanics. Upon graduation in 1948 he joined the Staff of the David Taylor Model Basin (DTMB) and during the following ten years held various positions in the Hydromechanics Laboratory. In 1958 he left his position as Head of the Towing Problems Branch and joined Cleveland Pneumatic Industries which later became Pneumo Dynamics Corporation (PDC). He was General Manager of PDC's Systems Engineering Division and in 1961 became a corporate Vice President. In 1964 he returned to DTMB where he became the Technical Manager of the Hydrofoil Development Program Office. In October 1969 he was appointed to his present position of Associate Technical Director for Systems Development and Head Systems Development Department David W. Taylor Naval Ship Research and Development Center. He is a licensed Professional Engineer in the state of Maryland an Honorary Life Member of ASNE and a Fellow of ASME. He also has been the author of a number of papers and reports in the field of Naval Engineering and has served as a member of the ASNE Council from 1972 to 1974 was a member of the ASNE Flagship Section Council (1977-80) and is currently a member of the ASNE Honors and Awards Committee. He became a member of ASNE in 1960 and received his Honorary Life Membership when he was awarded the ASNE Gold Medal for 1973 at ASNE Day 1974. Dennis J. Clark:received his Bachelor's degree in Civil Engineering from City College of New York in 1963. Upon graduating he joined DTMB's Structural Mechanics Laboratory where he worked on a number of full-scale trials of surface ships evaluating the structural integrity of icebreakers sonar domes and Hydrofoils. He eventually was responsible for the entire structural research program in support of the Hydrofoil Advanced Development Office and in 1971 joined the Hydrofoil Program Office as the Manager of Systems Integration. In that capacity he

In today's environment of rapidly escalating costs, increasing technological complexity, and growing threat, we must actively seek ways to improve our effectiveness in applying limited resources to the design of Navy ships. One important aspect of this process involves the development and application of new technology to ship design. An exhaustive treatment of this subject is clearly beyond the scope of a single technical paper. It is the Authors' objective, however, to acquaint the reader with the nature and role of the Navy's Laboratory Community in general and DTNSRDC in particular; to examine some recent initiatives taken at DTNSRDC and some key issues; and, hopefully, to contribute in some small way to the building of a stronger constructive partnership between ship development and design activities. The view is that from the perspective of a Navy Laboratory and pertains to the design of the ship itself as opposed to the weapons system.
