This article discusses the issue of interaction with the custom task workflows on clusters their execution. Since tasks on multiprocessor systems can be performed for long periods of time, they should be quasi-interactive, allowing the occasional appearance of the user to input corrective instructions. In this article a proxy service is proposed that is an extension of the event-driven job management subsystem on the cluster. When launching computational experiments with event control, then the event control subsystem agent executed on the computational nodes prepares the environment for tracking the events of the experiment by operational system means. After the computations are done the event control subsystem agent clears up operational system settings for tracking events. The role of proxy service is to interact with the event control subsystem, listen to events and output streams that come from the parallel program, keep track of changes in the parallel program filesystem in its own database, and when is asked return information on the parallel program state and files to a user interface, or feed input data back to the parallel program. The article also discusses an I/O agent that is launched on each node of the computational cluster immediately before starting the computational process. The agent normally intercepts stdin and stdout streams from the controlled process, but can also interact with it via sockets, increasing the capabilities of the computing process to interact with the user.

The study of the optical properties of BaSi2 films grown on n-type silicon by solid-phase epitaxy showed that the band gap of BaSi2 is about 1.20 eV. Formed Al/BaSi2/Si mesa-diodes showed the presence of two maxima in the photoresponse spectra at 1.15-1.20 eV and 1.5-1.6 eV at 300 K and spectra expansion to 0.7 eV at 80 K. Analysis of the I-V characteristics and photoresponse spectra at two biases showed that a BaSi2-n/Si-n isotype heterojunction is formed with a double barrier layer, quasi-linear I-V characteristics, and contribution of defect states to the photoresponse at 80 K. Band diagrams of the BaSi2-n/Si-n heterojunction with surface states at zero, forward and reverse biases were constructed, which made it possible to explain features in the photoresponse spectra at energies of 1.0-2.1 eV and the first detected IR photoresponse at 0.7-1.0 eV based on charging and photogeneration of defect states at 80 K. © 2020 The Japan Society of Applied Physics.

Gd2O2S:Tb is promising for energy-efficient lighting and display applications due to its high luminescence efficiency (LE). This work explores the use of reactive spark plasma sintering (SPS) to synthesis Gd2O2S:Tb nanocrystalline phosphors (NPs). It allows precise control over dopant concentration of Tb3+ and particle size over a streamlined simplify processing compared to conventional multi-step liquid-phase synthesis. Homogenous composition and structure, as well as enhanced LE of the as-sintered Gd2O22S:Tb NPs with 2-20nm particle size were demonstrated. Bright green emission occurs at 545 nm with a LE reaching 52.8 lm/W under UV excitation of 245 nm. Further consolidation of the as-sintered Gd2O2S:Tb NPs via non-reactive SPS can also be expected to yield highly dense ceramics. The innovative reactive synthesis strategies provide valuable insights into the design and development of high-performance NPs and ceramics. © 2024, The Authors. All rights reserved.

作者： Sergey S. Fetsov Alina S. Kim 1Institute of Automation and Control Processes FEB RAS 5 Radio st. Vladivostok Russia 2Far Eastern Federal University 10 p. Ajax Vladivostok Russia

A novel computational model based on the finite volume method is proposed for studying processes in heat-evolutional porous media. The developed model is implemented in OpenFOAM software. The problem of one-dimensional time-dependent gas flow through a porous heat-releasing medium is considered for testing the model. The computational results are compared with those obtained by the previously developed numerical procedure based on the finite difference method, and it is found that the performance of the proposed method is better than that of previously developed one.

The problem of sensor fault identification in mechatronic systems described by linear and nonlinear dynamic models is considered. To address the problem, sliding mode observers are used. The suggested approach for constructing sliding mode observers is based on the reduced order model of the initial system. This allows to reduce complexity of sliding mode observers and relax the limitations imposed on the initial system.

Recent progress in hybrid nanomaterials composed of dissimilar constituents permitted to improve performance and functionality of novel devices developed for optoelectronics, catalysis, medical diagnostic and sensing. However, the rational combination of such contrasting materials as noble metals and semiconductors within individual hybrid nanostructures via a ready-to-use and lithography-free fabrication approach is still a standing challenge. Here, we report on a two-step synthesis of Au-Si microspheres generated by laser ablation of silicon in isopropanol followed by laser irradiation of the produced Si nanoparticles in presence of HAuCl4 . Thermal reduction of [AuCl4] − species to metallic gold phase, along with its subsequent mixing with silicon under laser irradiation creates a nanostructured material with a unique composition and morphology revealed by electron microscopy, tomography and elemental analysis. Combination of such basic plasmonic and nanophotonic materials as gold and silicon within a single microsphere allows for efficient light-to-heat conversion, as well as single-particle SERS sensing with temperature feedback modality and expanded functionality. Moreover, the characteristic Raman signal and hot-electron induced nonlinear photoluminescence coexisting within Au-Si hybrids, as well as commonly criticized randomness of the nanomaterials prepared by laser ablation in liquid, were proved useful for realization of anti-counterfeiting labels based on physically unclonable function approach. © 2022, CC BY.

Data Quality Assessment for System Identification in the Age of Big Data and Industry 4.0

IFAC-PapersOnLine 2020年第2期53卷 104-113页

作者： Yuri A.W. Shardt Xu Yang Kevin Brooks Andrei Torgashov Technical University of Ilmenau Ilmenau Thüringia Germany University of Science and Technology Beijing Peking China BlueSP and University of the Witwatersrand South Africa Institute of Automation and Control Processes FEB RAS Vladivostok Russia

As the amount of data stored from industrial processes increases with the demands of Industry 4.0, there is an increasing interest in finding uses for the stored data. However, before the data can be used its quality must be determined and appropriate regions extracted. Initially, such testing was done manually using graphs or basic rules, such as the value of a variable. With large data sets, such an approach will not work, since the amount of data to tested and the number of potential rules is too large. Therefore, there is a need for automated segmentation of the data set into different components. Such an approach has recently been proposed and tested using various types of industrial data. Although the industrial results are promising, there still remain many unanswered questions including how to handle a priori knowledge, over- or undersegmentation of the data set, and setting the appropriate thresholds for a given application. Solving these problems will provide a robust and reliable method for determining the data quality of a given data set.

Solving nonstationary boundary value problems with piecewise linear boundary conditions for one-dimensional dynamics of deformable heteromodular elastic solid

引用

AIP Conference Proceedings 2021年第1期2448卷

process of propagating one-dimensional deformations in a heteromodular isotropic elastic half-space under nonstationary boundary loading is under consideration. Nonstationary boundary problems are solved with using an algorithm based on piecewise linear approximation of nonlinear boundary conditions. It is shown that this approach preserves the physical nonlinearity of model and at the same time allows us to pass to a related sequence of simpler problems with analytical solutions; all these solutions together are an approximation of a continuous solution of the original problem. Earlier the question concerned with freedom of choice of the number and position of the nodes of the approximating function was investigated for various forms of boundary conditions. The paper presents the solution of one-dimensional boundary value problem for nonstationary loading the heteromodular half-space in the “tension – compression – stop” mode. It is shown that the solution can have several non-intersecting branches due to the various positions of nodes in the piecewise linear function of boundary motion.

A silicon heterostructure with four layers of embedded gallium antimonide nanocrystals was formed on a Si(111) substrate by co-deposition of Ga and Sb using solid-phase epitaxy. Si(111)2 1-Sb surface reconstruction formed prior to the GaSb nanocrystal growth, which kept the nanocrystals from decomposition during the silicon epitaxial layer formation. P- and n-type structures were obtained using silicon of different conductivity types. In the 200-550 K temperature range they showed increases in both electrical conductivity and Seebeck coefficient compared with the bulk samples, which was explained by the peculiarities of the heterointerface band alignment and density of states at the Fermi level. The results open the way for creating multilayer structures with enhanced thermoelectric performance. © 2020 The Japan Society of Applied Physics.

The oxide layers on titanium were formed by plasma electrolytic oxidation technique in acid aqueous electrolytes containing sodium tungstate and copper acetate. The coatings with WO3-CuO or WO3-CuWO4 oxide layers have been formed in the electrolytes with H2C2O4 (pH~6) or H2SO4 (pH~4) accordingly. The coatings with WO3-CuWO4 have a developed surface architecture. The surface is constructed from coral-like structures with lamellar nanocrystals containing copper tungstate and tungsten oxide. The layers of tungsten oxide nanocrystals occupy the depressions between these structures. The band gap of the mixed WO3-CuWO4 oxide layers is 2.8 eV. © 2019 Trans Tech Publications Ltd, Switzerland
