Aktract-This paper gives a detailed account of a system environment for the treatment of general problems of image and speech understanding. It provides a framework for the representation of declarative and procedural knowledge based on a suitable definition of a semantic network. The syntax and semantics of the network are clearly defined. In addition, the(More)
Computer aided systems based on image analysis have become popular in zoological systematics in the recent years. For insects in particular, the diicult taxonomy and the lack of experts greatly hampers studies on conservation and ecology. This problem was emphasized at the UN Conference of Environment, Rio 1992, leading to a directive to intensify eeorts to(More)
The paper describes experimental results of a mediumvoltage, modular, 35 MW drive for Oil & Gas applications realized by interconnecting voltage-source three-level converters equally sharing the motor current. Drives rated for tens of Megawatts are increasingly needed as torque helpers for gas turbines in the Oil & Gas industry and one envisions that they(More)
This paper introduces a knowledge-based vision system for industrial environments. It is designed to control a cell in an assembly system. The images from the environment are taken as gray scale images. Based on a single image, the system has to recognize type and position of the recorded parts and to control their placement in the environment for further(More)
