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. ***.

In this paper, we present algorithms and experimental results for an automated layout synthesis procedure that is used in a high-level silicon compiler. The techniques consist of a unique approach to generalized cell synthesis, together with a novel solution of the placement and routing problem. Our algorithms take advantage of a larger space of possible solutions than is available in conventional, fixed-cell approaches to achieve compact and efficient ***, our techniques for cell synthesis are presented. Then, we describe our placement algorithm, in which the locations of the cells are determined by signal-flow considerations. Next, our pin permutation procedure is described. These permutations are not limited to the relatively few cases of logically equivalent pins, but rather, can exploit a much larger set of transformations involving the re-arrangement of the inner structure of the cells themselves. Finally, our techniques for both global and channel routing are discussed. Experimental results for a complete chip layout are included.

In this paper, we describe the YASC high-level silicon compiler which synthesizes compact chip layouts from hierarchical behavioral descriptions. A logic synthesis procedure generates sets of Boolean equations, including multi-phase clocks and any necessary interface logic. A novel technique for layout generation yields cells whose densities approach hand-crafted designs. Two-layer metal NMOS and CMOS technologies are supported, with flexible design rules. In addition to layout synthesis, logic, schematic and graph diagrams are generated directly from a powerful internal data base. The compiler, which runs under the UNIX^^ operating system, includes a menu-driven multi-windowing user environment.

The orthogonal collocation approach is now well known to solve, effectively, the state constrained optimal control problems. Mathematical programming technique was also used as an effective tool to construct the optimal trajectories. In this paper, a study is done on the efficiency and accuracy requirements of the combined orthogonal collocation and mathematical programming approach, as regarding the employed optimization algorithm, and the number of orthogonal collocation points. It is shown, by experimentation with numerical examples that Fletcher-Powell optimization algorithm is much more faster to produce convergence than Fletcher-Reeves algorithm. The efficiency can be a ratio of six-to-one. The results are compared with an alternative approach to solve the same problem. It is shown that the present algorithm is less costly than the alternative approach, although requiring more computation time. The choice is then a compromise one. As the number of orthogonal points increases, the resulting solutions are more accurate, but the convergence speed decreases. Experimentation with N, shows a save of five-to-one in computing time can be achieved with almost the same cost function. Finally, it is shown, by a numerical example, that uniformly distributed collocation points result in non-optimal solutions, which also violate the problem constraints. It is a numerical proof of the superiority of the orthogonal collocation approach.

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.
This paper presents a method of identification of nonlinear system with unknown time varying parameters based on an idea of orthogonal approximation of function. Here, block-pulse functions are chosen as the orthogona...
