This work is devoted to development of hybrid geoinformation system for making forecasts of possible flooded areas in the downstream water of the Irkutsk hydroelectric station with damages evaluation in conditions of extreme water content for lake Baikal and for effluents of the Angara river. For 3D model construction of the Angaras bed they used Atlas Map of the Angara River in Irkutsk hydroelectric power station up to 142 km on scale of 1: 10000 General plan of Waterways of the East Siberian basin ", Irkutsk, 1994. Due to lack of a digital model (map), a paper-based map was digitized using vectorizer program Easy Trace 7.99. Depth contours, marks and bank lines were also digitized. To combine the data about land and underwater terrain a specific software was developed using Delaunay triangulation method. The role of data layers in the construction of triangulation is specified. The layers contain information about: land relief, standing water levels, shore lines, underwater topography. Auxiliary triangulation is made according to the data whereof further information is revealed regarding heights levels to which shore contours are attached and in reference to which depths are measured. Hybrid geographic information system allows to simulate different scenarios of flooding and to determine the flood zones with account for underwater and land relief.

The approach is based upon declarative specifications of database applications (SDA). The specifications of database applications contain all the information about database structure, which is required to build a typical AIS (automated information system). The information is represented in its pure form, so the specifications are rather concise. The AIS'es are implemented using general algorithms, which are directed by the specifications. We have developed algorithms for such tasks as: user interface generation, query building, report generation, GIS interaction. Using the specifications of database applications and the algorithms the software system GeoARM was implemented. The technology considered was well-tried by use of the system GeoARM for development of several dozens of true-life AIS for different purposes.

The problem of open information exchange substantiates the perspective of SOA paradigm for the creation of infrastructure that supports interdisciplinary research. The infrastructure solves problems of service and data cataloging, publication and multiuser editing of data, deployment and execution of services and theirs compositions. The developed infrastructure effectively utilizes resources, adapts to environment changes and solves problems in biology, geography and ecology sciences.

We calculate the tensor meson exchange contribution to the interaction operator of muon and proton, which is determined by the tensor meson coupling with two photon state. For the construction of transition form factor T → γγ we use the monopole parametrization over photon four-momenta and experimental data on the decay width ΓTγγ. It is shown that tensor meson f2(1270) exchange gives essential contribution to the Lamb shift in muonic hydrogen ΔΕLs (2P – 2S) which should be taken into account for a comparison with precise experimental data.
Propositional satisfiability (SAT) is at the nucleus of state-of-the-art approaches to a variety of computationally hard problems, one of which is cryptanalysis. Moreover, a number of practical applications of SAT can...
