Abstract: The theory of probabilistic automata is still evolving discipline of theory of information. As in classical theory of automata, it might be a base for computations, can be exploited in design and verification of circuits and algorithms, in lexical analyzers in compilers computers in future. Minimization of any type of automata gives always saving in resources and time, and is important problem that has been analyzed for almost sixty years. Different types of automata are used for modeling systems or machines with finite number of states. In this article we show few specific type of probabilistic automata, especially the reactive probabilistic finite automata with accepting states (in brief the reactive probabilistic automata), and definitions of languages accepted by it. We present definition of bisimulation relation for automata's states and define relation of indistinguishableness of automata states, on base of which we could effectuate automata minimization. Next we present detailed algorithm reactive probabilistic automata’s minimization with determination of its complexity and analyse example solved with help of this algorithm.

Keywords: minimization algorithm, reactive probabilistic automata, equivalence of states of automata, bisimulation relation.

Abstract: Blindly copying and mimicking evolutionary processes in animated nature along with well developed mathematical models for them looses its base, the inevitable evolution looses its meaning. Instead the evolution by choice more and more establishes itself and it has much greater perspectives to spread. The experiments of evolution by choice is in an abstract mathematical domain where the models include numerous number of elements, i.e. much too bigger in number than the biological evolutionary models. The paper introduces the idea of evolving-by-choice ontologies, a juxtaposition of evolving ontologies with an evolution by choice algorithm. A principle scheme of evolving-by-choice ontology is introduced and the starting options of the model are presented. In total the fundamental problem for biologically inevitable evolution – prove that the solution space exists – in the case of evolving-by-choice ontologies is replaced by the problem to find the shortest path to the solution space.

Abstract: Improving management systems is getting more and more important and topical, as the organizational structure of modern society consists of many features, peculiarities, relations, and is continuously getting more intricate. Although the society has been complex for a long time, it is only now that we are starting to comprehend its real complexity. It has become obvious that changing a characteristic can easily cause or require change to other parts of the system. Attempting to achieve an enterprise’s highest efficiency, each modern executive should use computer modeling from time to time, as it is an efficient tool for management system research that weighs qualitatively and quantitatively characteristics of system functioning. A prerequisite of modern management is to know the principles and capabilities of modeling, be able to create research and use such models. This report considers the role of business modeling for modern management tasks. Generalizing theory development in the area along with international practices and domestic experience, the author chooses the main directions of modeling for modern management and those fields of management where applying computer modeling is more efficient.. This paper weighs perspectives of modeling used to solve business problems; considers modern modeling approaches used to describe architecture, develop operational models and carry out reengineering; briefs on existing techniques and instrumental tools used in modern business modeling.

Abstract: This study is a continuation of the development of the “Electronic Mosquito,” a minimally-invasive blood sampling and analysis device. Wireless communication is a pivotal feature of the Electronic Mosquito in terms of usability and future applicability. The present article describes the design process used to construct a working wireless communication link using an established and reliable protocol. The resulting wireless link performed to specifications, with an empirically determined range of about 20 feet. Power consumption analysis indicated that the wireless system could operate for 100 days off of a CR2032 battery without any power control, and likely longer if power management is implemented in the software. The adopted communication protocol also appears to be a likely candidate for the creation of a Personal Area Medical Network standard which could greatly benefit modern medicine as well as the Electronic Mosquito.

Abstract: Main features of a new method of expert knowledge elicitation – method of generalized interval estimations – and peculiarities of its using in decision making are presented. Expert estimation of an analyzed quantitative parameter is defined in the framework of the method by a set of intervals. This set may be shown on a plane (X, Y) by a curvilinear trapezoid. If densities of probability distributions were defined on Y-axis (“weights” of different interval estimations at their set) and on X-axis (for all interval estimations at the set) we received generalized interval estimation (GIE) of the parameter. GIE method may be used at different directions. Firstly, we may reduce GIE to mono-interval estimation averaging distributions on X-axis, taking into account their weights, and use then famous probabilistic methods to analyze problem. The average distribution is in fact a probability mixture of distributions on intervals of their set. Secondly, we may study complete structure of interval estimations that reflects expert knowledge in details. Here we automatically receive for resulting diagrams (X -parameter value, Y - level of probability) such probability distributions that are boundaries of all distributions of GIE (probability tube, or box). Besides we may receive probability distributions for different sections of p-tube both for parameter values and for probability levels and use these curves in the process of decision-making. At last, we may use GIE method as an instrument of scenario analysis in decision-making. Illustrative examples are given in the paper to demonstrate the decision-making, expert knowledge and scenario analysis aspects of the proposed approach.

Abstract: The subsystem of simulation model completion is discussed. This subsystem is one of the components of computer-aided design and simulation system Triad.Net. Triad.Net is dedicated to computer systems design. And it is well-known, that very often investigators do not know about the behavior in details of each component of computer system being under design in the early stages of this process. The paper considers an ontology-based approach for the incomplete simulation model analysis and its automatic completion. A behavior procedure for the undefined element is searched for in special database and included in simulation model. The paper considers the method of model completion, namely, introduces the concept of a “semantic type” and some conditions that should be fulfilled for an appropriate behavior procedure to be chosen. The base ontology of simulation model representation is discussed and the choice of language OWL is explained. The presented example shows the process of simulation model automatic completion, illustrates the use of semantic type and additional conditions. Besides, the paper describes the programming tools which provide an ontology-based automatic completion, presents the semiautomatic completion of partly described simulation model in simulation system Triad and the architecture of the program subsystem being under consideration.

Abstract: In this paper we present different approaches to multi-source data integration for the solution of complex applied problems, in particular flood mapping and vegetation state estimation using satellite, modelling and in-situ data. Since these applications are data- and computation-intensive, we use Grid computing technologies. In such a case computational and informational resources are geographically distributed and may belong to different organisations. For this purpose, we also investigate benefits of different approaches to the integration of satellite-based monitoring systems.

Abstract: Swallowable capsule endoscopy is used for non-invasive diagnosis of some gastrointestinal (GI) organs. However, control over the position of the capsule is a major unresolved issue. This study presents a design for steering the capsule based on magnetic levitation. The levitation is stabilized with the aid of a feedback control system and diamagnetism. Peristaltic and gravitational forces to be overcome were calculated. A levitation setup was built to analyze the feasibility of using Hall Effect sensors to locate the in-vivo capsule. CAD software Maxwell 3D (Ansoft, Pittsburgh, PA) was used to determine the dimensions of the resistive electromagnets required for levitation and the feasibility of building them was examined. Comparison based on design complexity was made between positioning the patient supinely and upright.

Abstract: Digital watermarking (WM) is the process that embeds an additional, identifying message called a watermark into a host multimedia object, such as audio, image or video for authentication purpose. Recently, digital WM technique, an information hiding technique has been investigated as one of the key authentication methods to maintain authenticity and security of multimedia content. By adding a transparent watermark to the multimedia content, it can be possible to make any malicious alteration detected to verify the integrity and the ownership of the digital media. During the last several years various WM techniques for still image have been extensively invented for software implementations due to the low data rate of these signals. Although the software approach holds an advantage of flexibility, certain computational restrictions may arise when attempting to operate at video rate or in portable devices. The hardware-level design offers several distinct advantages over the software implementation in terms of lower power consumption, reduced area and reliability. Therefore, there is a strong motivation for a move toward the hardware-based implementation for digital video WM system. In order to give a help for future related research works, this paper presents an up to date overview of digital video WM techniques and discusses the important considerations involving in designing VLSI architecture for a novel WM system in many ways. First of all, it goes through a brief survey on WM theory, laying out common classification criterions, discussing the properties of video WM techniques including the specific requirements as well as the comparison to image WM schemes. Various applications of video WM in practice are discussed. Since each WM application has its own specific requirements, WM design must take the intended application into account. Furthermore, the features of video WM implementations in software and hardware and comparison on those two approaches are presented from several points of view: major advantages, drawbacks and differences through the description of several examples of previous works. In addition, a versatile development methodology for hardware WM implementation including the general scheme of a proposed digital video WM system and testing using the custom breadboard are described.
