Abstract: various metaheuristics, such as method of simulated annealing, are currently used for solving the tasks of resource usage optimization and computation scheduling. Simulated annealing is a serial method and it is difficult to parallelize it. However, different methods of parallelization have been developed recently in order to improve the quality of the solutions and the time of algorithm execution. The subjects of the study are the methods of parallelization for annealing simulation, in particular, the method of independent starts with and without synchronization. As an example of simulated annealing implementation the authors select the method with thermal scheme “quenching” as the fastest one. The article shows analytical review of simulated annealing parallelization, with a selection of the most promising methods, for which a series of computational experiments was carried out. Scientific novelty of the work is in the discovery of new dependencies and trends that were not described previously in similar studies. In discussing the parallelized annealing simulation with synchronization the authors raise a question of the existence of the dependence of the quality of the solutions with not only the number of computing devices, but also with the frequency of the solutions exchanges. For asynchronous parallel simulated annealing the article shows a tendency to solutions improvement with the increase of the number of computing devices, while for synchronous simulated annealing a similar dependence was not found.

Abstract: Medical diagnostics is one of the most difficult tasks of practical health care. Currently, there is a need for appliance of information and communication technologies in medicine, especially in solving the task of creating diagnostic telemedicine systems. This is the cheapest and easiest way to organize telemedical diagnosis at any distance. A user-patient sends medical information to the system via telecommunication channels. The system prepares the diagnostic conclusion based on a set of symptoms received in real time and outputs the solutions to a patient. If the patient does not accept the decision, he may request the system solution from expert physicians. In that case the system organizes the dialogue with physicians in delayed mode. Then the system automatically generates and sends questionnaires to doctors of the assumed specialty. Then doctors form the diagnostic answers to the questions and send them by email. Thus, the telemedicine expert system for differential diagnosis is to perform a medical diagnosis in a reasonable time after the patient enters detected symptoms. Also, the system should allow the patient to communicate with physicians through the use of web technologies that allow patients to receive medical diagnosis outside the clinic. The authors suggest that architecture for this system should be based on the principles of creating web applications and describe the basic levels of web-based systems. The article presents a scheme of a database with a description of the tables for creating the system. This work is useful for software implementation of the medical expert system of differential diagnosis.

Abstract: In this paper the author concretizes the principles of modeling border activities and considers the sequence of development of methods and models for border security and their classification. The basic approach (the set of methods and techniques) to development of the concept of automation is in consistent decomposition of the domain based on the classification of measures. The elements of the domain are combined into a single system by identifying flow through processes, by the use of cycles of border activity and border control. The suggested classification of management methods for regime, prevention and border measures allows obtaining a complete and consistent list of border tasks to be automated. The article also reviews a methodology of automation of border activity, based on the decomposition of the process of border security. Building the automation concept for border activity involves the use of methods of systems analysis and systems engineering, ETOM methodology, the main provisions of the theory of law, criminology, theories of security, border studies and border metrics. In order to create a highly effective decision support systems in the field of border security management the author classifies the methods of border security. The article considers and substantiates the structure of regime, prevention, security, control and operational security measures. The block diagram of the processes of the first level is build and includes two parts: border security management processes and border units’ management processes.

Abstract: The subject of the study of movements of an administrative unit tax base are methods for constructing simulation models of the process of the tax base state management both as an object in the composition of the administrative unit and as the possibility of simulation of tax base movements for studying its’ behavior in further complicating of market relations both in between enterprises of administrative units and in between its administration and a single enterprise. Information technology of the state management of taxable base in its imitation models (being a tool in its composition) is necessary for the administrative unit of power and consists of a set of methods, ways and means for providing optimal allocation of resources in the process of giving a real taxable base a desired state. The study of taxable base motion as a real part of an administrative unit is founded on state management methodology for any object considered in any subject area, presented in the form of a structural model of the logical organization of methods and tools: - observation of the motion parameters of the object; measuring the value of at least one parameter of the motion of the object; simulation of the motion of the object; estimate of the parameters of motion of the object; the choice of alternative and decision making; forming a control action on the process of movement of the object out of the available resource. Scientific novelty of the proposed instrument in the form of a simulation model is in a new logical organization (i.e., the process of establishing new logical connections) of methods and tools that are part of the management process for specific object as taxable base movements proceeding under the influence of the external environment of competing subjects, systems and technologies from the infrastructure of the city and the district. The benefits of the proposed simulation model of the management process for the state of taxable base as part of the administrative unit is in the ability to successfully solve the problem of expansion of taxable base today, because the decision is needed by the authorities of any city, town, district and region. A tool allowing the authorities of the administrative unit gathering knowledge about the options for solving the problem of taxable base expansion is the mentioned above “Statistical Simulation Dynamic (SSD) model of the taxable base management process”. The basis of mathematical “decision support system” software, which is a part of the “Statistical Simulation Dynamic (SSD) model of the taxable base management process” can be formed of algorithms using the methods of statistical decisions, game theory, fuzzy sets and several methods of dynamic programming.

Abstract: In this paper, we present an extended stream processors texture generation model for displaying educational content in 3D virtual worlds. The model suggests conducting image-processing tasks on stream processors in order to reduce the load on CPU. The main objective of the paper is to provide the evaluation results of the suggested extended model based on a series of tests. The extension of the model consists of using fixed pipeline features of stream processors. The obtained results of performance evaluation confirm high efficiency and veracity of the generalized mathematical and programming models for image processing. High performance can be explained by specificity problem of generating educational content for virtual words because the source data for the synthesis of images and the data area for the resultant images are in the local memory of stream processors.

Abstract: the article describes a parameterization of models of radar images of groups of “string” and “cluster” point objects. The authors study probabilistic characteristics of sufficient statistics for their distinction, necessary for the selection of decision rules optimal according to specified criteria under different conditions of observation. The article reviews a method of modeling the distortion of observed reference chains that reduced all the diversity of observations down to two parameters: curvature of the trajectory of the chain and degree of deviations of observed coordinates of point objects from their reference position. This technique allows formalizing and reducing the complexity of comparing competing methods of identification chains. The paper lists features of software for testing competing algorithms of distinguish group of objects. The authors suggest using ratio of the diameter of the graph of hierarchical grouping of objects detected to the total length of the edges of this graph as the statistics of distinguishing. Based on these mathematical models by statistical experiments the authors obtained sample estimates of the laws of probability for distribution of the sufficient statistic for distinguishing different values of model parameters. Taking into account the complexity and the properties of the mentioned method of distinguishing chains and groups the authors recommend it to be used in the construction of systems of recognition of group of point objects in high priori uncertainty regarding the parameters of the conditions of observation for groups with power not less than 10. The proposed architecture of the software package allows testing detection algorithms with signature having various number and type of parameters.
