    Teleoperated robots used to reduce employee exposure to radiation and to achieve measurable and often significant cost savings are described. The robots are mobile, people-machine systems, with a human in the loop guiding their movements and operation. They are remotely operated vehicles that consist of three systems: a computer, a sensor, and a mechanical structure. They go into controlled radiat... View full abstract»

    A generic design process that uses computer-aided, constraint-directed searches is outlined. The process is described as a search over a state space that holds all possible combinations of values of state variables representing facets of the design process; i.e. it holds all complete designs. The use of intelligent search to reduce the amount of effort and the role of the human navigator are discu... View full abstract»

  • Distribution automation experiments with generic software

    Publication Year: 1991 , Page(s): 27 - 31
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (821 KB)  

    Design experiments demonstrating that low-cost, simple, effective distribution energy management systems (EMSs) may be implemented with a minimum of vendor software are described. The experiments provide a relational database solution to distribution automation and define the database procedures necessary to generate a power flow database. The description of the database for the equipment as well ... View full abstract»

    An integrated, computerized monitoring system that provides for the capture and analysis of vibration data is described. The heart of the system is the Transient Data Manager (TDM) Communications Processor (CP), a computer interface that captures data during machine startup or coastdown. In addition, steady-state data are captured during online machine operation. Data captured include current stat... View full abstract»

    An approach that combines automation of table lookup heuristic methods with transient energy function (TEF) methodology and conventional time simulation, taking advantage of the merits of each, is presented. The TEF method, which belongs to the class of direct methods of stability analysis, is described. It can be thought of as a generalization of the conventional equal-area criterion, which appli...
