A new concept of a robot manipulator with passive mobile base is proposed which can be safely used in a human-robot cooperation environment. A joint-based control scheme is developed to control the end-effector position of the manipulator which is tolerant to unexpected contact force with the manipulator's environment. The mobility the of base of the manipulator is passively exploited to attenuate the dynamic disturbance of the contact force and the joint configurations are re-adjusted according to the evolution of the position of the base to maintain performance of the given task. Effectiveness of the proposed method is verified by computer simulation and experimental evaluation is currently underway.

An aluminum layer of about 55 nm thickness has been awarding Compact discs the well-known shiny appearance. The layer serves as a reflector for the pick-up laser system reading out the digital information. In state of the art single disc coaters, deposition could be done within 1.1 s by means of dC magnetron sputtering although polycarbonate, from which Cds are made, withstands only very limited temperatures. Industrial demands on productivity, reliability, low energy consumption, high target utilisation and a constant layer quality require special design considerations on sputtering sources.

The criteria to be used in the construction of an efficient computerized man machine interface were studied and experimented in order to optimize plant management. These criteria concern choosing symbols, colours and browsing methods not only on the basis of consolidated ergonomic know-how, but also by experimentation and various tests with expert plant management staff. It was seen that this new type of interface allows the plant to be run in two ways: one with highly summarized plant information, and another with a more detailed analysis, should the operator require, which allows greater awareness in plant management.< >

One of the most interesting and important problems, met during the development of non‐pressurized impregnated paper cables for high voltage direct current, arose from the introduction of a long‐duration type test at thermal cycles under a dC steady voltage of twice the working voltage. dC cables manufactured according to a traditional paper insulating technique showed during the cooling phase of a thermal cycle a catastrophic fall of the dielectric strength of the order of 50 %. The reason for this fall is analysed both theoretically and experimentally and the way to overcome the obstacle is explained and discussed. Copyright © 1993 John Wiley & Sons, Ltd.

The rechargeable lithium/cobalt oxide electrochemistry is examined for its use in powering underwater vehicles. It has been successfullv developed in 30 amp hour capacity cells. A comparative studv with the silver oxide/zinc technology, most frequently used for this application, revealed lithium's superior performance. Lithium/cobalt oxide gave more charge-discharge cycles with 40-50% higher energy density. Lithium's advantage was especiallv marked at -2-degrees-C, where it cycled four times longer than silver cells. Projections indicate that, at the 600 amp hour cell size, the battery will have an energy density of 120 watt hours per pound resulting in a more durable and cost effective power source for naval vehicles than currentlv possible.

Advanced computing technology development now allows considerable computational power to be packaged in small, modular components for low costs. In particular, vector and array processor add-on boards offer a way to incorporate modern parallel capabilities into existing hardware systems. In addition to cost efficiency, the fact that these boards may be able to plug-in to existing computer systems provides both design flexibility and a more rapid way of upgrading deployed computer hardware. To take advantage of such processing capabilities, however, algorithm analysis must be performed to determine what functions can be efficiently off-loaded to the vector processing board, and to decide what parts of the original serial algorithm should be redesigned to take advantage of the new hardware architecture. This paper presents a case study of how these issues are being addressed in a real-time active sonar data processing system. Vector processing technologies are being analyzed for application to correlation sonar systems used for estimating ship velocity on submarines, surface ships, and autonomous underwater vehicles. Such a system is deployed on Trident II SSBNs and is meeting its current design objectives. However, real-time operation of the correlation sonar is computationally intensive and fully utilizes the processing power of the fielded computing hardware. Expansions in the accuracy and operating envelope of the system are desirable and are not limited by the physics or practical operation of the sonar system, but rather by the speed at which processing of hydrophone returns can be performed. This analytic feasibility study investigates the possibility of expanding the operating envelope through the use of vector processing technology, within the constraint that any hardware or software changes would have minimal impact on the deployed system. It is predicted that significant speedups and operating envelope expansions can be achieved by introducing vectorized ha

作者： COMSTOCK, EN BALES, SL GENTILE, dM Mr. Edward N. Comstock:is currently Head of the Hull Form Design and Performance Branch (SEA 3213) of the Naval Sea Systems Command. He received his B.S.E. degree in Naval Architecture and Marine Engineering in 1970 and his M.S.E. degree in Ship Hydrodynamics in 1974 both from the University of Michigan. Mr. Comstock began his career with theU.S. Navyin 1974 as a Seakeeping Specialist in the Hull Form and Fluid Dynamics Branch of the former Naval Ship Engineering Center. Achieving his present position in January 1982 Mr. Comstock was previously Head of the Surface Ship Hydrodynamics Section of SEA 3213 being responsible for recent hull form designs including DDG-51 MCM-1 and ARS-50. Before obtaining that position in 1979 Mr. Comstock's efforts were primarily aimed at developing and establishing seakeeping performance assessment and design practices. Prior to his employment by the Navy Mr. Comstock worked in the Structural and Hydrodynamics Group of General Dynamics' Electric Boat Division. A member of ASNE he is also a member of ASE and SNAME and has been active in supporting the efforts of the SNAME H-7 (Seakeeping) Panel SNAME HS-12 (Hull Instrumentation) Panel the National Science Foundation (NSF) and the NATO Armaments Group IEG6/Sub-Group 5 (Seakeeping). Ms. Susan L. Bales:has been associated with the David W. Taylor Naval Ship R&D Center (DTNSRDC) and its predecessor organizations throughout her professional career. She is currently Head of the Ocean Environment Group of the DTNSRDC Surface Ship Dynamics Branch (1561) and also serves as the DTNSRDC Program Manager of the Navy's Exploratory Development Program on Surface Waves. Her work documented by more than fifty technical publications has been directed primarily to ship seakeeping ocean environment and ship performance assessment problems. An internationally recognized authority in her field she is also active in several professional societies as well as the SNAME H-7 (Seakeeping) Panel the National Science Foundation (NSF) and the NA

The on-going debate regarding the merits of large versus small aircraft carriers raises several issues concerning the ability of various ship configurations to support sea based air operations. One such issue is the question of the relative seakeeping performance of ship alternatives. In an effort to shed some light on the matter, a comparative seakeeping assessment of nine air capable ships covering a wide range of size and hull form was performed. An evaluation of the impact of aircraft and ship motion limitations on sea based air operations and a comparison of the relative ability of the ships to conduct air operations while in a seaway are presented. The specific air operations considered are launch, recovery, and support of aircraft. The ships evaluated are CVN-71, CVA-67 (Mr), CVV, LHA-1, VSS-d, ddV-2, ddV-1d, dd-963, and SWATH-6. These ships have the combined capability to operate Vertical Takeoff and Landing (VTOL), Conventional Takeoff and Landing (CTOL), Short Takeoff and Arrested Landing (STOAL), and Short Takeoff and Vertical Landing (STOVL) type aircraft. results indicate that seakeeping performance generally degrades with decreasing displacement, that SWATH-6 performance is the least degraded, that elevator wetness can be an important degrader for ships with lower freeboards, that roll motion can be an important degrader for ships under 60,000 tons, and that percent time of operation is strongly dependent on the prevailing wave and wind environment.

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.
