The required configuration management and the necessary control of the Surface Ship Combat System elements demand that they be considered as integrated and tested in accordance with an integrated test plan utilizing an integrated test organization. The sometimes used approach of implementing a combat system test program based upon the individual combat system elements being independent, has proven to be less than satisfactory. Then is no question that some of the early testing at the unit, subsystem, and subprogram levels can be planned and conducted independent of a specific “end-item” combat System. This paper addresses the planning and implementing of combat system test with the emphases being upon the integrated phase of test and primarily the lead ship of a class. Information is presented to facilitate planning and implementing a combat system test program including use of shore facilities and integrating these activities with shipboard activities; when to form the test organization and what types of expertise are required; what are the key technical management tools; the proofing of test documentation; the need fordetailed “step-by-step” procedures and traceability of the specifiedrequirements; how to assist Ships Force; planning and stat using the conduct of the tests; integrating computer program and special testing into the test program; and the significance of early decisions on administrative and contractual arrangements.

CAMPBELL, JSTHE AUTHOR was born in Porterville. Calif.
in 1928 and joined the U.S. Nary in 1945 in the “Aviation Midshipman” Program. He received his designation as a Naval Aviator in 1950 and flew combat missions in Korea while still a Midshipman followed by participation in various operational and training squadrons until 1958 when he completed the Naval Test Pilot School Program. After a tour as an Engineering Test Pilot. he attended the Naval Postgraduate School Monterey. Calif. and was then assigned to the Fleet Computer Programming Center as a part of the NTDS development. Later he had operational tours as CIC Officer in the USS Enterprise and as AAW Officer on the Staff of Commander Task Force SEVENTY-SEVEN in Vietnam. During an interceding tour of duty he was the Program Manager for the TACDEW Training Facilities at San Diego Calif: and Dam Neck Va. After completing his active duty in the U.S. Navy Mr. Campbell joined Logicon Inc. and during the six years with the Tactical and Training Systems Division held various positions including Project Manager Department Head Assistant Director and Division Director prior to leaving in 1976 to join the Assistant Secretary of the Nary for R&D as Special Assistant for Weapons Systems Integration. In 1978 he joined the Staff at the Naval Ocean Systems Center as Associate Director for Command Control and Communications and Acting Head of the C3I Systems Department where he is charged with the development and operation of the C3Systems Integration Test and Evaluation Laboratory.

The increasingly important role of land-based test sites (LBTSs) in military command, control, and communications (C 3 ) is discussed, with particularreference to system integration, r&d, and testing. The LBTS at the Naval Ocean systemscenter (NOSC), San diego, is described in detail, and lessons learned from the operation of the and other LBTSe are considered in terms of both their tactical and strategic implications.

HAY, rAHOLTYN, CHMr. Robert A. Hayis currently a Welding Consultant
and prior to his retirement in 1977 was the Director of Welding. Engineering & Technical Services Department. Reynolds Metals Company a position he had held since 1974. He received his formal education in Pennsylvania and New Jersey with additional studies in Welding Metallurgy at the University of California Los Angeles (UCLA). after which he spent seven years at the New York Naval Shipyard where he was a Welding Supervisor in charge of underwater welders (divers) and other specialized welding applications. Subsequent thereto he worked for the Linde Company Division Union Carbide Corporation in the R&D Laboratory on the development of the inert gas-welding processes TIG and MIG and as a Technical Sales Representative. In 1959. he joined the Engineering Services Department Reynolds Metals Company as a Welding Engineer where he specialized in cryogenic applications welder training programs and marine construction and was the Resident Welding Engineer in New Orleans. La. during the construction of the 306-foot all-aluminum Trailer shipSacal Borincano.In 1963 he accepted a position with Aero jet General Von Karman Center Azusa Calif. as a Process Engineer on the development of the aluminum and stainless steel propulsion systems for the APOLLO and ABLESTAR Space Vehicles. during which time he promoted the use of an electron beam welding system and a high strength aluminum alloy to produce the reliability required of the APOLLO Space Unit. Mr. Hay rejoined the Reynolds Metals Company as Chief Welding Engineer where he produced the first high speed technical movie “The Effect of Arc Variation on Aluminum Welds” and also developed the widely used technical comic book “MIG Welding Aluminum”with Pete and Harry which was later translated into the Parsi language for use in the Mideast. A Life Member of the American Welding Society a Past Chairman of the Welding and Joining Committeeand a Past Member of SNAME. he has contributed numerous technical papers

Various thermal practices may be usedduring metal fabrication. Although certain operations are routine for steel, they are not for aluminum. The properties of aluminum are different from those of steel, and the effect of high temperature on each metal is different. Aluminum does not experience any color change while being heated to the melting point. Temperature control is essential in order to prevent damage, to minimize the loss of mechanical properties, and to safeguard against reduced corrosion resistance. Hot forming and flame straightening can be used effectively to fabricate aluminum provided adjustments are made to the shipyard's routine steel practices. Even with the best procedures the post thermal properties of thick, heavy, aluminum parts may be below the published minimums. Accordingly, parts that are exposed to high temperatures for extended periods of time should be designed with reduced properties in mind. Ship structures must meet prescribed fairness tolerances. distorted aluminum assemblies can be brought within standards through the use of a flame/quench technique. The shipyard's procedures must be approved for Navy work and scrupulously followed by trained crews in order to obtain acceptable results.

These proceedings contain the papers presented at the 4th International S- posium on Location and Context Awareness (LoCA) during May 7–8, 2009 in Tokyo,***-generation mobile and pervasive computing systems. Pervasive computing is a model of computing in which computation is everywhere and computer functions are - tegrated into everything. The ultimate aim is to make information, applications and services available anywhere and at anytime in the human environment in a ?uid manner appropriate to our current context. Once away from the desktop, we ?nd ourselves in a wide variety of contexts and hence situations. For computing to be relevant and useful in these emerging situations we must rely on a range of contextual cues. Context includes phys- logical, environmental, and computational data, whether sensed or inferred. In addition, context includes details of a user’s activities, goals, abilities, pref- ences, a?ordances, and surroundings. With location and context awareness we can expect computers to deliver information, services, and entertainment in a way that maximizes convenience and minimizes intrusion.
