Usually the work crew at a power plant is limited and insufficient to start multiple units simultaneously. Computer simulation of the unit commitment process has traditionally excluded such constraints on maintenance crews at the plants. This paper addresses this limitation, presenting an extension to the Lagrangian relaxation algorithm that accounts for crew constraints in the resulting unit commitment solution. The technique has been implemented on a large scale power system, and results are shown using actual power system data.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

Such a distributed processing heavily depends upon the successful networking and sharing of the resources. It has been well documented that for concurrent engineering practices, to develop reliable products in minimum turn around time, information should be fed to the design phase continuously. Thus a virtual design center (VDC) concept using the distributed resources, with real time audio and video interfaces between individuals at the distributed locations, is of utmost importance. With digital connectivity techniques such as integrated services digital network (ISDN) and frame relay becoming available around the public switched telephone network, the virtual design center concepts can be implemented more efficiently using these methodologies. Screen sharing for visual observation and interaction, file sharing for information access, and voice interaction are the main requirements for the development of the virtual design center concept. The authors describe the concepts and methodologies under investigation at Florida International University for implementing virtual design center.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

State-of-the-art systems are capable of recognizing tens of thousands of words in complex domains such as newspaper correspondence and travel planning. A major part of this success is due to advances in language modeling and search techniques that support efficient, sub-optimal decoding over large search spaces. The benefit from focusing a recognition system on a particular domain has motivated a steady progression from static language models towards more adaptive models that consist of mixtures of bigrams, trigrams and long-distance n-grams. Similarly, the availability of multiple sources of information about the correct word hypothesis has led to the advent of efficient multi-pass search strategies. The result is a powerful pattern-matching paradigm that has applications to a wide range of signal detection problems. Future research in large vocabulary continuous speech recognition will be directed towards developing more efficient means of dynamically integrating such information.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.

This generates a natural partitioning of the parameter space based upon the operating points of the plant. As a result, it may be wise to generate local control strategies at, the operating points rather than a single global strategy. This article describes a modular neural network architecture that generates a piece-wise continuous control strategy designed to fuse local strategies together to form a single strategy. The modularity is achieved through a gating network that controls the competition and cooperation of local experts. The gating network is a high order dynamical system network, while the local expert is a multi-layer feedforward network. The capability of this technique is demonstrated by building a neurocontroller for the two-link robot manipulator with two revolute joints.","PeriodicalId":334874,"journal":{"name":"Proceedings IEEE Southeastcon '95.
