  • Integral robust features based technique for optical identification of railway vehicles

    Identification of railway vehicles is relevant for the conversion from automatic control systems with manual data input to automatic modeling environment of train and vehicle. The most effective and economic inventory number recognition is optical recognition. But there is question about veracity in such technology. This paper represent the qualitatively new approach for optical recognition based on building integral robust constructive features of vehicles and allowed to significantly increase level of recognition veracity. Proposed technique investigated in introduction subject of automatic vehicle number recognition system (ARNV).  Computational experiments demonstrated relevance of proposed technique for using in optical recognition of vehicle numbers.

    Keywords: Automatic systems, number identification, vehicle, optical recognition, ARNV, robust features

  • Visa-free regime of Russia with Finland as a factor of influence on business life of Finland

    Estimates by the Finnish experts of prospects of introduction of a visa-free regime of Russia with Finland are considered. Estimates of its influence on business life of Finland are given. It is shown that 60% of respondents expect obtaining benefit by the companies from introduction of a visa-free regime, about 30% don't expect any consequences, and only 8% assume emergence of problems.

    Keywords: visa-free mode, business life, Russia, Finland.

  • Technique of microinjection in axons of nerve cells, surrounded by dense glial sheath, using ultrasound vibration of microcapillary

    Intracellular microinjection - a method of direct introduction of cellular organelles and solutions of substances into living cells. The technique of microinjection into nerve cells by puncturing their processes - axons , which are often surrounded by a dense glial sheath, are described. To puncture the sheath a special injector transmitting microvibrations of ultrasonic frequency on the injection capillary was designed. The results of using the proposed microinjection technique for introducing fluorescent marker in large axons of model object - crayfish ventral nerve cord, to visualize the morphology of axons, were shown.

    Keywords: intracellular microinjection, neuron, axon, glial sheath, ultrasound vibration, piezoelectric transducer

  • 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.

  • Channeling of X-ray fluorescence excited in hollow microcapillaries.

    The possibility of channeling X-ray fluorescence inside the hollow microvascular at the energy of the exciting radiation in the vicinity SiL2, 3 - absorption edge has been researched. Theoretically obtained the angular distribution of the field passing through the microchannels. The calculation model of inhomogeneous waveguide layer with the generation of X-ray fluorescence inside the walls of the microchannels shows the possibility of escape of radiation at large angles.
