  • 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.

  • Kinematic investigation of the mechanism of the ladle turning of the rope excavator

    The research devoted to the kinematic mechanism for turning rope of ladle excavator, in the article considered the part of the trajectory of the work process: this process make the turning of the grip relatively to the arrow with the same time turning ladle relatively to the grip. The ladle turning is made because of additional kinematic connection between the ladle and grip and / jr the arrow and implementing internal forces due to the mutual position of the corresponding arrow and grip.

    Keywords: the rope excavator, the ladle turning, kinematics, the analitical investigation

  • 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.
