Bottom fishing equipment employed by scallopers and trawlers routinely damage or break important Navy Oceanographic cables resulting in substantial repair coats and unacceptable system interruption. The Civil engineering Laboratory (CEL), sponsored by the Naval Facilities engineering Command (NAVFACENGCOM), has been developing and validating an engineering concept for a Deep Ocean Cable Burial (DOCB) system. This DOCB system will providethe Navy with an efficient, effective and reliable means of burying cables 3-feet deap in ocean mediments, at speeds not less than one knot, to water depths of 6,000 feet. The DOCB system b a remotely controlled machine which underruns and buries existing (previously laid) cables. It is powered and controlled from a surface ship via an electromechanical umbilica cable. The machine is self-propelled by ducted thrusters and supported on water lubricated skids. The excavation system computer an orbital vibrating plowshareand a vertical waterjet. Full-scale field testing at CEL baa keyed on three areas: •. Quantifying the reduction in drawbar force achieved by applying orbital vibration to an upward cutting plowshare. •. Evaluating a Vertically impinging jet nozzle for depth of a cut M a function of jet operating parameters. •. Demonstrating the effect on the soil drag of a flat-bottomed skid due to forcing a thin layer of water between the skid and the seafloor. The field teats of an orbital vibratory plow were performed in a 1 to 2 psi clay simllar to that found on the ocean floor. The results showed that a 70% reduction in drawbar force was achieved by applying an elliptical orbital vibration. It was also shown that the vibration feature would split or push aside buried rocks which would have stalled a conventional stationary plow. The water jet tests demonstrated that a 2 1/2-in. nozzle cuts 36-in. deep in 1 to 2 psi clay. The nozzle pressure was 75 psi and flow was 1,200 gpm. The water jet did not produce a clearly defined trench, b

Dynamic Simulation is defined as the hardware and software required to present to the student operator visual and audible cues and responses that are the same as those encountered when operating the control Consoles aborad ship. This type of simulation is considered essential to the development of operator skills for critical tasks. Less critical tasks can be practiced using static simulation devices. This paper discusses the utilization of these types of training devices to train Navy crews. An overview of the Machinery control systems of the FFG 7 and AO 177 Class ships is discussed to provide an understanding of state‐of‐the‐art equipment development. The training programs for these two ship Classes are then reviewed to show how simulation devices are currently used by the Training Community, and this is followed by a brief discussion of the additional benefits that also are derived. © 1980 by the American Society of Naval Engineers, Inc.

Lower Fleet operating costs and independence from foreign fossil fuel resources are the goals of energy conservation efforts for Navy surface ship. This paper describes an evaluation of a wide variety of energy conservation approaches. A standard 20-knot, 300-hour Destroyer mission is established so that all of the approaches can be compared on a total fuel required basis. The approaches studied include use of aluminum hull construction; light weight machinery; trail-shaft or cross-connect operation for twin screw ships; improved performance propulsors; advanced power plant types, such as COGAS or cruise engines; use of energy storage techniques to improve ship service generator performance; electrical load reductions; improved performance ship service generators; hull drag reductions; crew size reductions; design margin reduction; reduced performance requirement (such as top speed); and habitability standard reductions. The overall results can be effected by reductions in range requirements as well. Mission duration was held constant at 45 days throughout the study. The results of the study indicate that the combination of these various possible improvements may reduce the fuel used to be as low as one-third of the current levels. Weight reductions are very effective for achieving significant fuel savings.

A pattern recognition system is divided into two parts, a receptor and a categorizer. In this research, a creative receptor is designed, and then an effective pattern recognition system based on the receptor is constituted. The receptor is composed of a set of unique matrix operators which allow it to perform efficient feature measurement extraction. The feature measurements are ranked in effective order, based on another function of the receptor. For the categorizer, a well-known optimization theory is applied. To evaluate the performance of this system, some evaluation functions are defined. Therefore, the receptor mechanism is optimized by the functions. This system is experimentally evaluated by computer simulations.

THE SHINPADS SERIAL DATA BUS

引用

Naval Engineers Journal 1979年第2期91卷 164-172页

作者： KUHNS, RICHARD C. The Author received his BS degree in Electrical Engineering from the South Dakota State University in June 1960. He joined SPERRY UNIVAC Defense Systems Division in June 1960 where he is now Manager of the Surface Combat Systems Group in the Navy Systems Engineering Department. He is currently active in the development of Navy Command and Control Systems. He has been active in the field of Navy systems computer digital communications analysis and design and was responsible for the system design of the NTDS Serial Interface specified in Military Standard MIL-STD-1397.

The Shipboard Integrated Processing And Display system (SHINPADS) Serial Data Bus is a high speed digital interconnect system designed to provide a real time data bus communication facility for Naval Electronic systems. The Serial Data Bus (SDB) can be used to interconnect devices currently using Military Standard MIL‐STD‐1397 Input/Output Interfaces and it has been designed to suit the needs of Naval Combat systems. The SHINPADS Serial Data Bus was specified with an eye to the future. A large growth margin was designed into the system, while minimizing costs, by properly distributing functions between software, firmware, and hardware. The Serial Data Bus protocol enables future evolution to Fiber Optic Transmission without impacting system software. The Serial Data Bus provides the potential for accomplishing many of the features attributed to Distributed Processing systems. However, the accomplishment of Distributed Processing improvements can only occur through proper and enlightened system design. © 1979 American Society of Naval Engineers

His earlier experience with the Department of the Navy included the Engineering Interface Management Office in the Bureau of Ships the Foreign Ship Systems Engineering Office and Switching Systems Design Office at RCA Service Company and he served for four years in the U.S. Navy as an Electronic Technician Petty Officer. In addition to ASNE he is a member of the Association of Scientists and Engineers and is the Executive Director (NAVSEA) for the 1978-79 term. In addition to several outstanding performance awards and citations for achievement Mr. Ryan received the Navy Meritorious Civilian Service Award for exceptional contribution to the development of the AEGIS Weapon System. Mr. Jack Berlin received his Bachelor's degree in Electrical Engineering from the City College of New York and his M.S. degree in Electrical Engineering from Columbia University. He spent eight years in the Radar and Microwave Electronics Section of the Naval Material Laboratory. Subsequently. he has had extensive experience in Radar and Fire Control Systems. This has included responsibility for the design and field evaluation of the GFCS MK 87 Radar. From 1972 to 1973 he was the Sperry Program Manager for the Fire Control System (FCS) MK 92. His current assignment is Assistant Manager for New Developments of Missile and Gun Fire Control Systems for the U.S. Navy. He is a member of the Tau Beta Pi and Eta Kappa Nu Honorary Societies.

The MK 92 Fire control system (FCS) & a new, integrated, highly reliable and light-weight U.S. Navy Fire control system for missile and gun control. This system, which is in production for the FFG, PCG, PGG and PHM Ship Classes, provides the detection and automation required for modern naval warfare. Search radar data & presented at a very high rate at the operator's console, a highly integrated man-machine interface. Utilization of monopulse and “track-while-scan” techniques result in multiple target tracking capability. The system console(s) offer a self-contained command and control capability and, in addition, standard digital computer channels provide the versatile interface with the ship's command and control, integrating the complete engagement process. Error cancellation techniques are employed to obtain high performance accuracy even under severe environmental conditions. The low manning requirement for both operation and maintenance is a key system attribute for all applications. Comprehensive “at-sea” evaluations, performed by the U.S. Navy, demonstrated successful system operation in all modes of surveillance, multi-target tracking and simultaneous missile and gun engagements. The “at-sea” performance record of the FCS MK 92 was cited by the Chief of Naval Operations to have established new standards for Naval Surface Weapons systems.

作者： GUPTA, V.K. RAMANI, N. Geological Branch Division of Mines Ministry of Natural Resources Toronto Ontario Canada System Dynamics and Control Group Department of Electrical Engineering University of New Brunswick Frederiction New Brunswick Canada

Gupta, V. K., and Ramani, N., 1978, A Note on Convolution and Padding for Two‐Dimensional Data, Geophysical Prospecting 26, 214–217. Filtering of gridded data by means of two‐dimensional generalized convolution results in a loss of data along the edges of the map. This loss can be counteracted by ‘padding’– filling the surrounding of the input map with some kind of data. Padding by algebraic extrapolation is assumed to be better than surrounding the maps with zeroes. A Føsrtran IV routine for padding by algebraic extrapolation is available from the authors.

Facilities Maintenance (FM), as currently performed by shipboard personnel, requires a considerable expenditure of man—hours and material resources and is not performed efficiently nor effectively. Potential solutions to underlying problems were studied on portions of an operational ship of the FF 1052 Class. The study indicated that: 1) a significant reduction in man—hour expenditure and cost to the Navy is feasible through a systematic innovation program, 2) skill and knowledge of FM Team personnel is improved, and 3) shipboard spaces are cleaner and better maintained with FM innovations. The next phase of the project includes the total ship, and it is planned to commence in July 1978 aboard FF 1052, FFG 7, and LST 1179 Class ships. © 1978 American Society of Naval Engineers

An Approach to Analyzing Biped Locomotion Dynamics and Designing Robot Locomotion controls

引用

IEEE Transactions on Automatic control 1977年第6期22卷 963-972页

作者： Golliday, C. Leslie Hemami, Hooshang Communication and Control System Laboratory The Ohio State University Columbus OH 43210 United States Department of Electrical Engineering The Ohio State University Columbus OH 43210 United States

An approach to analyzing biped locomotion problems is presented. This approach applies the principles of Lagrangian dynamics to derive the equations of motion of locomotion gaits, state-variable techniques to analyze locomotion dynamics, and multivariable feedback to design locomotion controls. A robot model which has no knee joints or feet and is constrained to motion in the sagittal plane is chosen as a sufficiently simple model of a biped to illustrate the approach. A goal of the analysis is the design of a locomotion control for the robot which produces a walking gait having a velocity and stride length similar to those of a human walking gait. The principle feature of the approach is a much deeper understanding of the dynamics of biped locomotion than previous approaches have provided.

作者： K. Fujii N. Takeda Y. Kogure T. Neda H. Kawahara M. Abe Power Generation Control System Engineering Tokyo Shibaura Electric Co. Ltd Fuchu Works Tokyo Japan Control and Instrumentation Department Power Tokyo Shibaura Electric Co. Ltd Tokyo Japan

This paper presents a description of recent computerized power generation plant automation and advanced man-machine interface systems. The automation software system is called COPOS (Computerized Optimum Plant Operation system), and the advanced man-machine interface software system is called PODIA (Plant Operation by Displayed Information and Automation). The authors describe, first of all, practical methods applied to the full automation of a fossil fired power plant by COPOS. For example, there is the fundamental philosophy of plant operation phases separation, sub-control systems separation, modes separation and WCD (Work control Drive). Also described is the COPOS software system, which features the problem oriented language (FILL IN BLANKS) called PLANT TABLES. Lastly, the authors describe the development of the displayed control panel, which makes effective use of many graphic color CRTs for advanced man-machine interface. The fundamental philosophy described in the paper is throughly useful and applicable to other process plants
