  • Software tools and biological databases for building hypothesis on protein-protein interactions after proteomics profiling

    The authors suggest two approaches to constructing hypotheses about the interactions of proteins on the basis of the results of tracking the changes in their levels during the studied biological process. The first approach is based on the use of machine mining of biological texts, which are freely available on the Internet. The second is related to the execution of database queries on binary protein-protein interactions . To specify the experimental context in obtained protein networks, filtering of the protein entities on the basis of needed ontology from database Gene Ontology was used.

    Keywords: text mining, data base, protein-protein interaction, protein networks

  • Use of Space Facilities for Positioning during Air and Space Information Processing

    Photometric principles of measurements have found a wide recognition and a wide application in different fields of human activity. It is stipulated by the introduction of photogrammetric works of new technology for obtaining primary information about the locality. At present for obtaining high quality and highly exact airophotographic data digital wide format photographic cameras are used and photogrammetric processing of digital pictures is carried out at special digital photogrammetric work stations.
    A great importance is attached to photogrammetric methods during the monitoring of lands for information providing of state realty cadastre. At present land state monitoring is a modern technical trend to provide this cadastre with the necessary graphic and digital documents.
    Photographing of small territories (dacha settlements, agricultural buildings etc.), when the scale of airophotography is ten or more times less than the scale of map-making, is quite possible because the object can be photographed on two pictures that is to be located on one stereo pair. This article is devoted to photogrammetric processing of a single stereo pair. At this space facilities for positioning (GLONASS, GPS) secure the coordinates and altitudes of points of photographic. When space signals are properly synchronized with the work of the photograph camera shutter and careful determination of the elements of adjustment of space antenna to the relative centre of projection (s) of camera is carried out the coordinates of projection centres can be used as supporting geodetic points.
    Point realization of the above-mentioned terms allows to decrease the number of supporting points necessary for outside orientation of model to one. It should be located at the end of stereo pair opposite its middle. While designing redundant supporting points (for control and improvement of exactness) they should be located in the corners of stereo pair.  

    Keywords: photogrammetry, stereo pair, single model, conditions of complanarity and collinearity, elements of orientation, points for photographing, GLONASS, GPS, theory, algorithm.

  • Psychosemantic modeling perception of political order by student of Grozny 2013

    The results of modeling perception psychosemantic political order among students of Grozny in 2013. The study involved 120 people. Modeling based on the classical method of semantic differential Charles Osgood . A comparative analysis of average semantic portraits. Calculated levels of emotional perception of the political order. Perception of order in the Republic: 0, 423052 , Russia: 0.351604 . The basis of the binding model is a theory of two ideal points (extended  method ideal point Coombs ): emotional attitude measured by proximity to the image of the real image of the ideal constructs in semantic space as a whole, rather than individual coordinates. In accordance with the general concepts of "good" and "evil" are calculated ideal "positive" and "negative" constructs. Further, under the theory of catastrophes developed model allows calculations on the ideal proximity to two points. Found that the level of perception described by the potential perception of the fourth degree. A stationary point - stationary states equation of the third degree. Potential itself depends on two factors: evaluation and activity. Based on a group approach, the method of calculation of the binding model and evaluation factors and the activity of the two proximity to two of the ideal points.

  • Magnetic properties of multiferroics BiFeO3, (BiLa)FeO3 and (BiNd)FeO3 electrets formed by corona discharge

    Recently, BiFeO3  multiferroics have drawn a great deal of attention due to their superior ferroelectric properties in epitaxial thin film form in comparison to counterpart bulk single crystals or ceramics. In this work we present the results on magnetic properties of multiferroic ultrathin films (30-300 nm) of BiFeO3, (BiLa)FeO3 and  (BiNd)FeO3  obtained by sputtering in transverse high frequency discharge, vacuum laser oblation and metalorganic chemical vapour deposition  on monocrystalline  substrates of (001) SrTiO3, (100) MgO and  (100) Al2O3. The concentration of Bi, La и Nd in dodecahedral sublattices was varied. A novel effect of treatment of multiferroic films in a negative corona discharge has been investigated. It is demonstrated that the magnetisation may be increased by up to 35%  whilst the change in    is not noticeable. This effect does not depend on neither film composition no technological method.

  • The motor vehicle model for integrated navigation systems

    Modern ultra-tight integration structure of strapdown inertial systems and global positioning system, based on the linearization of the navigation measurements and linearization of measurement errors models, are not not applicable for motor vehicles navigation. The adequate standard stochastic model of the vehicle perturbed motion has been synthesized. The model can be used for the integration Kalman filter. Such correlations can result in poor real-time estimation accuracy of navigation parameters of motor vehicle.

  • Simulation of failures and their elimination on financial markets with the events flow generated by a binary tree

    A financial market on a stochastic basis with a filtration generated by the binary tree is considered. A plugin simulating failures on this market is constructed. We mean by a failure the following situation on the financial market: when passing from a time moment  to the next one new events arise but discounted price of the fixed type stock does not change. A failure generates the incompleteness of the market (the set of martingale measures of this market is infinite). By modelling of a weak deformation it is possible to reduce the set of martingale measures to a unique measure. Thereby the price of every contingent claim is uniquely determined. This price may be considered as "fair price".

    Keywords: Stochastic basis, probability measure, financial market, binary tree, arbitrage free, completeness, weak deformation, martingale measure, plugin.

  • Deformed martingales and their properties

    With the help of so-called deformations (that is of probability measures families on sigma-fields forming a filtration) a notion of deformed martingale is introduced. This notion generalizes the classical concept of martingale with discrete time. We differ two sorts of deformed martingales: deformed martingales of the 1-st and the 2-nd type. Similarly deformed sub- and supermartingales of the 1-st and the 2-nd type are introduced. We prove that infimum of arbitrary family of deformed supermartingales is a supermartingale and that convexe function of deformed martingale is a deformed submartingale. In addition, for deformed martingales of the 2-nd type a telescopic property is obtained.

  • The algorithm for constructing the trajectories of moving objects in a video based on optical flow

    At present, the development of algorithms is particularly relevant high-level analysis of video sequences, including tracking of objects in a video stream and their implementation in information and communication systems. In the proposed approach the pretreatment step uses optical flow calculation for each frame video sequence, as well as low-level features (such as a representation of each pixel in the color space YIU). For moving objects optical flow is more important than for a stationary background and allows you to find the foreground objects in video sequences and adjust the weighting function in determining the histogram similar to the adjacent frames, taking into account the motion of objects.
