UDC 681.2 Towards a Universal Distributed Brain for Mobile Multi-Robot Systems / Sapaty P.S., Sugisaka M.// Mathematical Machines and Systems. - 2003. - N 3,4. - P.3-20. The paper describes a new concept for the creation of a universal distributed brain for mobile multi-robot systems. This brain spatially interprets a special high-level language in which mission scenarios can be efficiently formulated and implemented, with cooperative work of robots being a derivative of the parallel interpretation process. Due to the universal nature of the scenario language proposed, which navigates in a unity of physical and virtual worlds and operates with both information and physical matter, the approach may form a new basis for the development and massive production of advanced distributed multi-robot systems. The latter may have a variety of important applications in both civil and defense areas, especially for the support of complex operations in open, unpredictable, and hazardous environments. The presented technology extensively uses globally coordinated mobile program code on the implementation level, which provides its high flexibility and robustness. Figs.: 13.

The neural-like growing networks used in the intelligent system of analysis and prediction of tactic-technical characteristics of contradictory parties are under consideration in this paper. All operations on processing the image and also classification and storage of the information about the images and their further identification are made extremely by mechanisms of neural-like networks without usage of complex algorithms requiring considerable volumes of calculus. At the conforming hardware support the neural network methods allow considerably to increase the effectiveness of the solution of the given class of problems, saving a high accuracy of result and high level of response, both in a mode of training, and in a mode of identification.

In the paper on the basis of analysis of the existent languages and systems of programming from the point of view of subjectfields, data and structures, decomposition elements, static and dynamic of describing program modules, processes, technologies of programming and the level of intellectualization, the evolution of discussed program means has been traced. The prognosis of the future languages and systems of programming peculiarities is made on the base of studied evolution processes. Particularly, the future languages of programming, so as some existent, will combine different orientations, get the futher development of abstracting data, knowledge, structures, means of management, and will contain the nuclear and specialized means for adaptation and self-development. Structure- and subject-orinted technologies will be replaced by semantic (sense) programming, using the existent technologies. The future languages and systems of programming will contain means and mechanisms of supporting parallel, parallel / consecutive work and also mechanisms of providing the high level of fail-safety and failurestability Tabl.: 1.

We propose a new approach to associative memories using kernel machine methodology. Basing on Hopfield-type pseudoinverse associative memories we developed a series of kernel-based hetero- and auto-associative algorithms. There are convergence processes during examination procedures even for continuous data. Kernel approach enables to overcome capacity limitations inherent to Hopfield-type networks. Memory's capacity does not virtually depend on data dimension. We provide theoretical investigation for proposed methods and proved its attraction properties. Also we have experimentally tested them for tasks of classification and associative retrieval. Tabl.: 1. Figs.: 5. Refs.: 8 titles.

UDC 681.3 Simulation and Optimization of Large Scale Subsurface Environmental Impacts; Investigations, Remedial Design and Long Term Monitoring / Larry M. Deschaine, PE // Mathematical Machines and Systems. - 2003. - N 3,4 . - P.201-218. The global impact to human health and the environment from large scale chemical / radionuclide releases is well documented. Examples are the wide spread release of radionuclides from the Chernobyl nuclear reactors and the mobilization of arsenic in Bangladesh. The seriousness of these issues is represented by the activities of the World Health Organization, the Environmental Protection Agencies in Europe, the United States, and the like. The fiscal costs of addressing and remediating these issues on a global scale are astronomical, but then so are the fiscal and human health costs of ignoring them. An integrated complete methodology for optimizing the response(s) to these issues is presented. This work addresses development of global optimal response policy design for large scale, complex, environmental issues. It is important to note that “optimization” does not singularly refer to cost minimization, but to the effective and efficient balance of cost, performance, risk, management, and societal priorities along with uncertainty analysis. This tool integrates all of these elements into a single decision framework. It provides a consistent approach to designing optimal solutions that are tractable, traceable, and defensible. Subsurface environmental processes are represented by linear and non-linear, elliptic and parabolic equations. The state equations for multi-phase flow (water, soil gas, NAPL), and multicomponent transport (radionuclides, heavy metals, volatile organics, explosives, etc.) are solved using numerical methods such as finite elements. Genetic programming is used to generate simulators from data when simulation models do not exist, to extend the accuracy of them, or to replace slow ones. To define and monitor the subsurface impacts, geostatistical numerical models, Kalman filtering and optimization tools are integrated. Optimal plume finding is the estimation of the plume fringe(s) at a specified time using the least amount of sensors (i.e. monitoring wells). Long term monitoring extends this approach concept, and integrates the spatial-time correlations to optimize the decision variables of where to sample and when to sample over the project life cycle for least cost of achieving specified accuracy. The remediation optimization solves the multi-component, multiphase system of equations and incorporates constraints on life-cycle costs, maximum annual costs, maximum allowable annual discharge (for assessing the monitored natural attenuation solution) and constraints on where remedial system component(s) can be located. It includes management overrides to force certain solutions be chosen or precluded from the solution design. It uses a suite of optimization techniques, including the outer approximation method, lipschitz global optimization, genetic algorithms, and the like. A discussion of using the WAVE-WP algorithm for distributed optimization is included. This system process provides the full capability to optimize multi-source, multiphase, and multicomponent sites. The results of applying just components of these algorithms have produced savings of as much as $90,000,000(US), when compared to alternative solutions. This was done without loss of effectiveness, and received an award from the Vice President of the United States. Refs.: 45 titles.
