  • 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.

  • Methodology to evaluate the feasibility and effectiveness of remediation of soils contaminated by oil and oil products, the biological indicators

    To evaluate the effectiveness of remediation of soils contaminated with petroleum or petroleum products, it is advisable to use the method for determining the integral indicator of biological condition (IPBS) of the soil, calculated on the most informative biological indicators. If, before reclaiming the difference between the IPBS contaminated and uncontaminated (background) soil is less than 10%, it is advisable not to carry out remediation. If the value of IPBS re-cultivated soil and uncontaminated soil IPBS value differ by less than 10%, then reclamation carried out efficiently.

  • 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.
