For example, the most widespread kind of reactors-that is cylindrical-in capacitively coupled plasma generators the excitation of plasma has a place at the center of the reactor, and in inductively coupled plasmas-on periphery. According to told, usage of the inductor and the capacitor of the resonator for connection the RF power source with the reactor we receive an opportunity to maintain a discharge in all volume of the reactor, increasing by this the power efficiency of the plasma generator. Combining a principle of hybrid plasma excitation with multiway discharge excitation with use of the distributed source of energy, one can maintain in the reactor with large linear dimensions a uniform plasma torch.","PeriodicalId":20531,"journal":{"name":"Proceedings KORUS 2000.

In the CAS system, the real 3-D position of the surgical probe is overlapped with the patient's pre-acquired 3-D image. This 3-D position detector is called a 3-D navigator and there are several techniques to detect the real 3-D position of the probe. In this research, the authors propose a new method using two camera system with one image grabber. Using this new method, simultaneous capture of a stereo image is possible by one frame grabber. So the authors can minimize errors due to time lag between images and further reduce costs. Left and right LEDs can be separated by a simple color processing algorithm on a PC. The authors are planning to separate three LEDs by applying further color information to each LED. This will offer faster calculation of the 3-D positions of the LEDs. And another approach which can eliminate the control line between system and probe is progressed. This cordless probe will provide convenience in surgical work.","PeriodicalId":20531,"journal":{"name":"Proceedings KORUS 2000.

The application of this method reduces the necessity of a nonlinear algebraic system solution. The special iterative algorithm of a solution of the indicated system is offered, in which for each step the solution of two linear systems is made. In this case the reconstruction error of the required factors is generated by an arbitrary enough choice of transfer function order of the shaping filter and by the iterative character of a nonlinear system solution.

Developing multi-user software seems a non-trivial problem for the necessity of providing parallel process interaction. The geoinformation AS (Markov and Ostrast, 1999) is of the following structure of process interaction. For each user connected, a session is created as a process. Each session has a time limit, after expiration of which the unused session is deleted. The main process carries out process creation/deletion and processing of the global session list. A lump of processes and the necessity of their synchronization have required modeling AS software for validating its correctness. The formalism of PS-nets has been used by the authors as the model of representing the parallel processes (Markov et al., 1997). With its help, the problems of validating AS software correctness have been analyzed.","PeriodicalId":20531,"journal":{"name":"Proceedings KORUS 2000.
