This report presents the results of the development of method of forming of motion laws for mechatronics objects (MO) along trajectories with the desired speed. Desired trajectories are described by third order parametric splines. Analytical expressions describing the dependence of the rate of change of the parameter from the laws of change of given speed and information about the parametric form of a trajectories are obtained. They allow to move the program point along the trajectory accurately at a given speed. The described approach does not require iterative calculations and allows to perform all necessary calculations in real-time even on low-power onboard robots' computers.

We present a method for building and texturing a continuous watertight mesh using a hole filling algorithm based on volume diffusion. A multilevel octree-based technique with the weight function being built along both the normal and line of view is proposed. A parallelized computational procedure for a multicore processor is presented which enables significant reduction in computation time. © 2015 institute of Physics and Technology.

The comparative study of static estimators (soft sensors) for a multicomponent distillation process based on the industrial and calibrated rigorous model datasets is considered. The sequence of distillation columns of an FFC unit is analyzed as an industrial case study. The contribution of the paper is to develop a method aimed at incorporating a priori knowledge about process in terms of rigorous models for static estimator design when the training sample is small and contains measurement errors. The superiority of a constrained optimization approach for SE design over conventional robust M -estimator is reported. The system of constraints is derived from a calibrated rigorous model of an industrial plant. © 2016

Porous silicon (PS) layers were formed on silicon substrates treated with compression plasma flow. Lateral size and density of pores formed on the substrates treated with plasma are by 25% larger than that on untreated substrates. Photoluminescence intensity of the PS layers, formed on the plasma treated substrates (PT PS), is twice higher than that of the PS layers, formed on untreated substrates. Three month exposure of normal PS and PT PS layers to the air led to the photoluminescence intensity increase by 3 and 5.7 times, respectively, as well as to the peak position shifting towards long wavelength region by 3.1 nm, in the case of PT PS layer. The photoluminescence intensity increase is attributed to the reduction of the dangling bond density because of passivation by oxygen. © (2016) Trans Tech Publications, Switzerland.

Detection of acoustic emission waves in composite plates by fiber optic sensors

AIP Conference Proceedings 2017年第1期1909卷

The paper provides an analysis of acoustic emission signals recorded with fiber optic sensors during the propagation of ultrasonic waves in a polymer composite material. The fiber optic sensors for acoustic emission were constructed according to the scheme of an adaptive holographic interferometer. Unlike piezoelectric sensors, fiber optic sensors are distributed type sensors. This imposes certain features on the detection of signals in plates in which fiber optic sensors are embedded. It is established that the spectrum of acoustic emission signals differs in different directions of wave propagation. The local maxima of the spectrum are determined by the mode of wave propagation in the plate in different directions and the location of fiber optic sensors.

Optical absorption of one-particle electron states in quasi-zero-dimensional nanogeterostructures: Theory

作者： Sergey I. Pokutnyi Yuriy N. Kulchin Vladimir P. Dzyuba Chuіko Institute of Surface Chemistry National Academy of Sciences Ukraine Institute of Automation and Control Processes FEB Russian Academy of Sciences Russia

The paper is devoted to the theory for the interaction of an electromagnetic field with one-particle quantum-confined states of charge carriers in semiconductor quantum dots. It is demonstrated that the oscillator strengths and dipole moments of the transitions for one-particle states in quantum dots are large parameters, exceeding the corresponding typical parameters for bulk semiconductor materials. In the context of the dipole approximation, it is demonstrated that the large optical absorption cross sections in the quasi-zero-dimensional systems enable the use of such systems as efficient absorbing materials.

In the paper we examine the problem of optimization of parameters of technological process for obtaining a molten pool with a needed depth on the surface of the metal sample under the thermal local laser treatment. A mathematical model of heat distribution during thermal laser treatment is simplified to a linear problem of heating a half-space, that can be used for plates of finite thickness. Despite a number of assumptions, this approach gives satisfactory qualitative and quantitative understanding of the heating stage. The accepted model allows us to control the quality criteria of the surface layer and, above all, its main feature - the depth of the molten pool by selecting the optimal parameters of laser radiation. To solve the optimization problem the algorithm based on the scanning method of the search space (the zero-order method of conditional optimization) has been built. The obtained results can be used both as preliminary recommendations for setting variable parameters of the real technological process and as prediction of phase and structural states of the irradiated material.

Smoldering of porous media: numerical model and comparison of calculations with experiment

引用

Journal of Physics: Conference Series 2017年第1期894卷

作者： N A Lutsenko V A Levin Institute of Automation and Control Processes FEB RAS Vladivostok 690041 Russia Far Eastern Federal University Vladivostok 690950 Russia Institute of Mechanics Lomonosov Moscow State University Moscow 119991 Russia

Numerical modelling of smoldering in porous media under natural convection is considered. Smoldering can be defined as a flameless exothermic surface reaction; it is a type of heterogeneous combustion which can propagate in porous media. Peatbogs, landfills and other natural or man-made porous objects can sustain smoldering under natural (or free) convection, when the flow rate of gas passed through the porous object is unknown a priori. In the present work a numerical model is proposed for investigating smoldering in porous media under natural convection. The model is based on the assumption of interacting interpenetrating continua using classical approaches of the theory of filtration combustion and includes equations of state, continuity, momentum conservation and energy for solid and gas phases. Computational results obtained by means of the numerical model in one-dimensional case are compared with the experimental data of the smoldering combustion in polyurethane foam under free convection in the gravity field, which were described in literature. Calculations shows that when simulating both co-current combustion (when the smoldering wave moves upward) and counter-current combustion (when the smoldering wave moves downward), the numerical model can provide a good quantitative agreement with experiment if the parameters of the model are well defined.

The most important factors influencing the processes of the PD are: the properties of the insulation, picture of the electric field in the core of the transformer, the location of the inclusions as potential defects (its “energy coordinates”), the electrical and physical properties of the potential defects (defect size, breakdown and extinction voltages of the PD, the discharge volt-amps diagram). Report focuses on analytical describing of the PD arising process. There are used both the circuit theory and the theory of electric field. First, permittivity, joule and polarization losses are used as the parameters of the insulation. Second, inclusion charge and area of field distortion are estimated in terms of analytical description of the electric field around inclusion. Further, the equivalent impedance of the environment relative to inclusion seeks in terms of analysis of two electric field modes (breakdown mode and short circuit mode) and with Thévenin theorem. Inclusion during PD time regards as a two-pole circuit element. The impedance together with the inclusion discharge volt-amps diagram are used for formalization of the description of PD current and estimation of the extinction voltage value.
