     Automated citation graph building from a corpora of scientific documents
     Computer Research and Modeling, 2012, v. 4, no. 4, pp. 707-719

     In this paper the problem of automated building of a citation graph from a collection of scientific documents is considered as a sequence of machine learning tasks. The overall data processing technology is described which consists of six stages: preprocessing, metainformation extraction, bibliography lists extraction, splitting bibliography lists into separate bibliography records, standardization of each bibliography record, and record linkage. The goal of this paper is to provide a survey of approaches and algorithms suitable for each stage, motivate the choice of the best combination of algorithms, and adapt some of them for multilingual bibliographies processing. For some of the tasks new algorithms and heuristics are proposed and evaluated on the mixed English and Russian documents corpora.

     Keywords: text mining, machine learning, information extraction, citation graph, bibliography, matching, record linkage, labeling, segmentation, conditional random fields.

     Computer simulation of plastic deformation of FCC copper nanocrystal in the process of uniaxial tension in a direction [001] is performed by methods of molecular dynamics and a static relaxation. It is shown that thermoelastic martensite transformation is responsible for plastic deformation, FCC lattice is reconstructed into HCP lattice. Orientation relationship of contacting phases is identified.

     Comparative analysis of optimization methods for electrical energy losses interval evaluation problem
     Computer Research and Modeling, 2013, v. 5, no. 2, pp. 231-239

     This article is dedicated to a comparison analysis of optimization methods, in order to perform an interval estimation of electrical energy technical losses in distribution networks of voltage 6–20 kV. The issue of interval evaluation is represented as a multi-dimensional conditional minimization/maximization problem with implicit target function. A number of numerical optimization methods of first and zero orders is observed, with the aim of determining the most suitable for the problem of interest. The desired algorithm is BOBYQA, in which the target function is replaced with its quadratic approximation in some trusted region.

     Keywords: optimization methods, electrical energy technical losses, distribution networks, BOBYQA.

     Motion control of a rigid body in viscous fluid
     Computer Research and Modeling, 2013, v. 5, no. 4, pp. 659-675

     We consider the optimal motion control problem for a mobile device with an external rigid shell moving along a prescribed trajectory in a viscous fluid. The mobile robot under consideration possesses the property of self-locomotion. Self-locomotion is implemented due to back-and-forth motion of an internal material point. The optimal motion control is based on the Sugeno fuzzy inference system. An approach based on constructing decision trees using the genetic algorithm for structural and parametric synthesis has been proposed to obtain the base of fuzzy rules.

     Keywords: optimal motion control, self-locomotion, genetic algorithm, structural-parametrical synthesis, decision tree, fuzzy logic.

     Calculation of magnetic properties of nanostructured films by means of the parallel Monte-Carlo
     Computer Research and Modeling, 2013, v. 5, no. 4, pp. 693-703

     Images of surface topography of ultrathin magnetic films have been used for Monte Carlo simulations in the framework of the ferromagnetic Ising model to study the hysteresis and thermal properties of nanomaterials. For high performance calculations was used super-scalable parallel algorithm for the finding of the equilibrium configuration. The changing of a distribution of spins on the surface during the reversal of the magnetization and the dynamics of nanodomain structure of thin magnetic films under the influence of changing external magnetic field was investigated.

     Keywords: Monte-Carlo method, super-scalable algorithm, Ising model, simulation of PMOKE-images.

     Phase transition from α-helices to β-sheets in supercoils of fibrillar proteins
     Computer Research and Modeling, 2013, v. 5, no. 4, pp. 705-725

     The transition from α-helices to β-strands under external mechanical force in fibrin molecule containing coiled-coils is studied and free energy landscape is resolved. The detailed theoretical modeling of each stage of coiled-coils fragment pulling process was performed. The plots of force (F) as a function of molecule expansion (X) for two symmetrical fibrin coiled-coils (each ∼17 nm in length) show three distinct modes of mechanical behaviour: (1) linear (elastic) mode when coiled-coils behave like entropic springs (F<100−125 pN and X<7−8 nm), (2) viscous (plastic) mode when molecule resistance force does not increase with increase in elongation length (F≈150 pN and X≈10−35 nm) and (3) nonlinear mode (F>175−200 pN and X>40−50 nm). In linear mode the coiled-coils unwind at 2π radian angle, but no structural transition occurs. Viscous mode is characterized by the phase transition from the triple α-spirals to three-stranded parallel β-sheet. The critical tension of α-helices is 0.25 nm per turn, and the characteristic energy change is equal to 4.9 kcal/mol. Changes in internal energy Δu, entropy Δs and force capacity c_f per one helical turn for phase transition were also computed. The observed dynamic behavior of α-helices and phase transition from α-helices to β-sheets under tension might represent a universal mechanism of regulation of fibrillar protein structures subject to mechanical stresses due to biological forces.

     Keywords: phase transition from α-helices to β-sheets, thermodynamics of transition from α-helices to β-sheets, molecular modeling, fibrinogen, fibrin fibers, Molecular Dynamics, GPU.
