The book is divided into four topical areas: Artificial Intelligence section includes papers on Humatronics, Fuzzy Logic, Robotics, Cell, genetic and Probabilistic Algorithms, Incomplete Data and Similarity Relations, and Fast Neural Networks. Computer Security and Safety section includes a variety of issues, from Error Detection in Block cipher to Visual Cryptography Methods. Image Analysis, Graphics and Biometrics section deals with the extraction of meaningful information from images and methods for uniquely recognizing humans based on intrinsic physical traits or behaviors. Computer Simulation and Data Analysis section concerns a computer program that tries to simulate an abstract model of a particular system and change the data with the aim of extracting useful information and facilitating conclusions.
