Unstructured peer-to-peer systems are loosely coupled, highly autonomous systems without hierarchy. Usually, flooding-based routing mechanisms are used for sending messages through the application layer overlay. Due to the limited scalability and high network load experiences, the paper suggests an improvement to reduce the traffic and overall performance: a peer remembers recently forwarded answers, so that he may route the next query messages with the same contents only to the relevant neighbor, not to all of them. Preliminary network simulations have shown promising results.","PeriodicalId":337983,"journal":{"name":"The IEEE Region 8 EUROCON 2003.

Generating units, the only controllable elements for which four variables are associated, were given special attention, since they influence to great extent both speed and robustness of any power flow method. In this paper, the standard procedure in which one sets the generator-bus active power output and voltage magnitude has been replaced by an innovative approach where generator-bus voltage magnitude and voltage angle are scheduled. The method relies on the bus admittance matrix, which due to applied bus ordering in layers has block tridiagonal sparse structure. A new technique for Gaussian elimination and back-substitution for such matrices has been developed. The results from five test systems have shown superiority in both time and robustness of the proposed method over the well-known fast decoupled power flow method.","PeriodicalId":337983,"journal":{"name":"The IEEE Region 8 EUROCON 2003.

Control functions are implemented on logic controller, which is a discrete event supervisory system for execution of parallel, synchronized and sequential control functions. To design a control logic of such a machine, appropriate specification and design methods have to be introduced. This paper introduces a matrix based modular logic controller design. The modular logic controller is specified and formalized using matrix representation of Petri Nets (PN). The matrix representation is supplemented with PN next-state function and discrete event controller equation which enables the simulation of the system and analysis of its performances before the target system is actually built. The target system in this paper is a cutting machine transport system. Using the proposed method, the properties of studied system are simulated and analyzed.","PeriodicalId":337983,"journal":{"name":"The IEEE Region 8 EUROCON 2003.
