An intelligent and robust voting service is proposed. The novel voting service, is capable of forming a consensus based on performance of redundant applications in the value, time and reliability *** voter is distributed using a hot backup approach to ensure timely recovery in the event of voter failure. Specification diversity is advocated in order to improve upon the effectiveness of design diversity. The voter is designed to be a system building block, embedded in a framework of design tools which will allow the developer to express control concepts, such as deadlines, priorities, re-plication and voting.

An improved SSDA (sequential similarity detection algorithm), which may be used to determine similarity in a more efficient manner than the SSDA currently in use, is introduced. The algorithm saves computation time and improves performance compared to the current SSDA. The problem of target tracking, used as an example, and calculation of performance indexes of SSDA are introduced to optimally implement the algorithm. Two series of frame images are simulated from real data to demonstrate the efficiency of the improved SSDA for target tracking.< >

Some teaching works on the course of Artificial Intelligence (AI) at Purdue University given by Professor King-Sun Fu are introduced. Especially, some research works on expert systems at the AI course made by the graduate students and directed by Prof. Fu are dealt with. Three examples of expert systems, in quality control, robot programming, and product evaluation, are given respectively. In this way, the author want to cherish his emotion for Dr. ***.
This paper uses the concepts and technologies of the expert systems to the robot planning. Some examples of these planning systems have been presented. Finally, the planning performances of these systems have been com...

LUEDEKE, GFARNHAM, RBJR.George Luedeke
Jr.: received his BS degree in Mechanical Engineering from Massachusetts Institute of Technology and his MS degree in Product Design from Illinois Institute of Technology. Early in his career Mr. Luedeke joined General Motors Corporation as a designer responsible for development of people mover and rail rapid transit systems. From 1964 to 1974 he was with Hughes Aircraft Company. At Hughes he performed analyses and developed designs for a wide variety of program and proposal efforts such as: High Speed Ground Transportation (DOT) Task Force Command Center (NAVY) Panama Canal Marine Traffic Control Center (Panama Canal Co.) Royal Iranian Navy Command Center (Iran) Tactical Information Processing and Interpretation Center (Air Force) and WALLEYE CONDOR and PHOENIX Missile Systems (NAVY). He also had marketing development responsibilities related to the diversification of Hughes resources in civil business areas such as: Automatic train control (WMATA BARTD SCRTD) water/sewage treatment plant automation (Santa Clara County) Aqueduct Control (SWR) Hydrometeorological data collection (BPA WMO) and Salton Sea basin systems analysis (Dept. of the Interior). He was responsible for combat system integration for the Hughes 2000T Surface Effect Ship (SES) proposal. He also conducted detailed studies concerning ship flexure for the Improved Point Defense Target Acquisition System Program and for the definition of operational High Energy Laser weapon installations on a series of conventional monohulls (DLG DD and CVN). Since 1974 Mr. Luedeke has been employed at RMI Inc. (formerly Rohr Marine Inc.). During this time he has held several positions. His responsibilities have included directing a number of studies on advanced SES concepts managing activities defining mission/cost effectiveness of military and commercial SES's including defining the operational benefits and enhanced survivability characteristics of cargo SES's for high speed military sealiftfor NA TO and Southeast Asia

This paper will present the results of a marketing, engineering, and economic analysis of advanced marine vehicles done by IMA Resources, Inc. and RMI, Inc., in support of a Maritime Administration project to study “Multimode Express Shipping”. The study was conducted in 1981 and examined the economic benefits of using advanced marine vehicles as express cargo vessels in domestic and international service. Commodity characteristics, desirable express carrier rates, and potential high payoff service and route alternatives were identified. Advanced marine vehicles were surveyed and sized to meet desirable deadweight and block speed objectives. The costs of operating these craft on a variety of trade routes were calculated using an advanced marine vehicle economic analysis program. Revenues, expenses, break-even, profit and loss, cash flow requirements, tax summary and economic indicators (i.e., cost/ton – mile, etc.) were projected over the expected life of the vehicles as was return on investment. Traffic density and market penetration considerations narrowed the field of choice to smaller sized advanced marine vehicle carriers (i.e., 50 and 250 ton deadweight) and to three international and five domestic routes.
