Advanced Computer Systems

Advanced Computer Systems is a collection of forty selected papers presented to the Eighth International Conference on Computer Systems, October 2001 in Mielno, Poland. These papers provide a comprehensive summary of practice and research progress in information technologies: Recognition, Security and Safety concentrates on the widely-known problems of information systems security. These chapters show the new cryptographic data protection algorithms, methods for recognition of individual biometric characteristics, which can be easily used in authorizing secure procedures for the users information systems. Methods of Artificial Intelligence presents methods and algorithms which are the basics for the applications of artificial intelligence environments. These chapters include fuzzy classifiers to analyze statistical data in the economic area, genetic algorithms applications to synthesize neuron and fuzzy regulators, and the fuzzy set theory for experts systems. Intelligent Agents and Distributed Activities includes laboratory research on multiagent intelligent systems as well as upon their applications in searching information, negotiating and supporting decision. An adaptive knowledge system is also presented here as a basis of a multiagent system. Tools for creating remote teaching systems (XML language, Petri Networks) and problems to support remote teaching by means of a knowledge base are also discussed. Distributed Productions Networks and Modeling Complex Systems present production processes in distributed shared virtual environment, virtual solution of integer optimization problems, and a queuing approach to performance optimization in the distributed production network. Attention is also paid to complex dynamic economic and engineering systems.
