In this paper the problem whether or not a human being can plan a tour for a mobile robot with a camera so that all changes in the room are detected within a time limit is investigated. A tour simulator and a game based on it are developed. The plan of the winner of the game is used for a driving real robot. It is shown that this plan is two times shorter(More)
Mobots (mobile robots) remote–controlled by human operators are more and more widely used for watching and guarding. A mobot should not be controlled by an occasional person. A human being has to show specific ability to be a good mobot operator. This ability is individual for each person and can be discovered with the help of an experiment which is(More)
Scalability and fault tolerance are important features of modern applications designed for the distributed, loosely-coupled computer systems. In the paper, two-layer scalable structures for storing data in a distributed RAM of a multicomputer (SD2DS) are introduced. A data unit of SD2DS (a component) is split into a header and a body. The header identifies(More)
– The paper presents resource allocation optimization in Critical Chain Project Management (CCPM). The cheapest project schedule is searched with respect to time constraints. The algorithm originally developed for the hardware-software co-design of heterogeneous distributed systems is adapted to work with human resources and CCPM method. The results of the(More)
The main purpose of this research is adaptation of critical paths method [1] to the processes defined in BPEL. The critical path method is the specification based and simulation oriented method. In the paper it is show that under some assumptions the BPEL process may be considered as an embedded system, in which tasks are like services and communication(More)
