Most neural network models are energy based models and there is no guarantee that the network converges to a global optimal solution. A new neural shortest path network model is proposed in which no special convergence procedure needs to be performed. The network can work in a purely asynchronous mode, and is guaranteed to reach the global optimal solution.< >

We present ExPro—a real-time knowledge based system for process management. This system is designed to provide process setup, monitoring, and supervisory control capabilities for a real-time semiconductor manufacturing environment. The specific process selected for development and demonstration purposes is rapid thermal oxidation (RTO), a technique used in the controlled formation of thin silicon dioxide layers for silicon integrated circuits. This is an ideal application domain for process management system development since we can readily obtain direct process variable feedback in real-time from the equipment. ExPro demonstrates several novelties, not the least of which is a modular design. It includes an integrated analytical simulator whose primary responsibilities are to predict process parameters a priori and to provide the necessary information on the growth of the oxide during the process. The knowledge base, in cooperation with the simulator, achieves a high degree of accuracy for control of the thickness of the wafer.
A tasking query language (TQL) for aiding very general analysis of Ada tasking in a Petri-net-based environment is discussed. An important principle of TQL's design is that of hiding the formalism upon which the a...

An intelligent hybrid system architecture is proposed for the design of plastic parts. To facilitate the concept of concurrent engineering, an object-oriented design environment is recommended. Problems with previous intelligent design systems are discussed. Using neural networks in conjunction with expert systems may provide the route to a more flexible design space. The necessary architecture to achieve these goals is described. A working model of the system was created. This model is discussed in detail.
This paper critically studies approaches that use the theory of fuzzy sets for multi objective decision making with linear programming. Two main approaches are distinguished: one that converts the problem into a singl...

A tasking query language (TQL) for aiding very general analysis of Ada tasking in a Petri-net-based environment is discussed. An important principle of TQL's design is that of hiding the formalism upon which the analysis framework is built. Instead, TQL defines a language by which queries of Ada interactions themselves can be expressed. Examples of TQL's capabilities are presented, and a sample analysis session using the gas station program is described.< >

A method for automating the search for codes that have particular structural features is described. A pattern language is used to specify the pattern of desired code. The benefits of using a pattern language include a higher level of abstraction in specifying patterns and the power to specify complex patterns which are impossible to express in grep type languages. A system that accepts these patterns and locates code fragments in C source files is described.< >
The neural-network model based on the theory proposed by Wilson and Cowan has been simulated by using digitized real images. Mathematically, the model is based on coupled nonlinear differential equations that describe...
