Modern detectors of cosmic gamma-rays are a special type of imaging telescopes (air Cherenkov telescopes) supplied with cameras with a relatively large number of photomultiplier-based pixels. For example, the camera of the TAIGA-IACT telescope has 560 pixels of hexagonal structure. Images in such cameras can be analysed by deep learning techniques to extract numerous physical and geometrical parameters and/or for incoming particle identification. The most powerful deep learning technique for image analysis, the so-called convolutional neural network (CNN), was implemented in this study. Two open source libraries for machine learning, PyTorch and TensorFlow, were tested as possible software platforms for particle identification in imaging air Cherenkov telescopes. Monte Carlo simulation was performed to analyse images of gamma-rays and background particles (protons) as well as estimate identification accuracy. Further steps of implementation and improvement of this technique are discussed. © 2018 Evgeny B. Postnikov, Igor V. Bychkov, Julia Y. Dubenskaya, Oleg L. Fedorov, Yulia A. Kazarina, Elena E.

A distributed data warehouse system is one of the actual issues in the field of astroparticle physics. Famous experiments, such as TAIGA, KASCADE-Grande, produce tens of terabytes of data measured by their instruments. It is critical to have a smart data warehouse system on-site to store the collected data for further distribution effectively. It is also vital to provide scientists with a handy and user-friendly interface to access the collected data with proper permissions not only on-site but also online. The latter case is handy when scientists need to combine data from different experiments for analysis. In this work, we describe an approach to implementing a distributed data warehouse system that allows scientists to acquire just the necessary data from different experiments via the Internet on demand. The implementation is based on CernVM-FS with additional components developed by us to search through the whole available data sets and deliver their subsets to users' computers.

Abstract. We consider problem of Quality Management system (QMS) development for Irkutsk Regional Oncological Dispancery. The system is intended to organize the process management of medical treatment according to the standard ISO 9001:2015. QMS software subsystems are synthesized as a result of a logical inference of a set of subgoals (a scenario) with a hierarchy of modules represented in the LogTalk programming language within Model Driven Architecture (MDA) paradigm. The source Computational Independent Model is represented as a set of BPMN2.0, SysML and CMMN diagrams. The models are imported and stored as ontology A-boxes on an ontology server. The models are transformed into Platform Specific Models with following source code and initial data population. Additional data for the transformation are provided from Linked Open Data compliant sources. Usage of such kind of MDA allows us to develop QMS on the abstract model level in most cases and involve domain specialist in the formal part of the development. Rengineering business processes of the medical institution should result in patient treatment quality improvement, as well as formalizing the processes, giving ideas for automation, data accumulation and processing. © 2018 CEUR-WS.

Intrinsic multipole moments of the non-Gaussian wave packets

arXiv

arXiv 2018年

作者： Karlovets, Dmitry Zhevlakov, Alexey Faculty of Physics Tomsk State University Lenina Ave. 36 Tomsk634050 Russia Matrosov Institute for System Dynamics and Control Theory SB RAS Lermontov str. 134 Irkutsk664033 Russia

The charged wave packets with non-Gaussian spatial profiles are shown to possess intrinsic multipole moments. The magnetic dipole moment and the electric quadrupole moment are found for a wide class of the packets, including the vortex electrons with orbital angular momentum l, the Airy beams, the so-called Schrödinger's cat states, and their generalizations. For the packets with no phase vortices, the electric quadrupole moment is shown to grow quadratically with the packet's width, |Qaß| ∼ e • s?2 , while it is also |l| times enhanced for the vortex beams. For available beams of electron microscopes, these multipole moments are relatively easily adjusted and can be quite large, which affects the packets' electromagnetic fields and also allows one to develop new diagnostic tools for materials science, atomic and molecular physics, nuclear physics, and so forth.

Journal of Physics: Conference Series 2019年第5期1368卷

作者： I V Bychkov G A Oparin A G Feoktistov I A Sidorov S A Gorsky R O Kostromin A V Edelev Matrosov Institute for System Dynamics and Control Theory SB RAS Lermontov Street 134 Irkutsk Russia 664033 Melentiev Energy Systems Institute SB RA Lermontov Street 130 Irkutsk Russia 664033

We represent a new approach to the development and use of a subject-oriented heterogeneous distributed computing environment for solving large-scale problems of energy security research. Both the development of scalable applications (distributed applied software packages) and the computing resources integration are conducted using the Orlando Tools framework. It supports the collaborative application development based on the continuous integration of their software. Computation management tools in Orlando Tools are integrated with a multi-agent system. We propose special multi-agent tools for the heterogeneous resource allocation in the environment. These tools apply knowledge about the subject domain specifics of solved-problems and computing environment characteristics. The effectiveness of such management is highlighted by the results of solving practical problems of energy security research.

Studying the natural gas market under demand uncertainty using a heterogeneous distributed computing environment

Journal of Physics: Conference Series 2019年第7期1333卷

作者： V I Zorkalzev A V Edelev S M Perzhabinsky I A Sidorov A G Feoktistov Melentiev Energy Systems Institute Lermontov St. 130 Irkutsk Russia 664033 Matrosov Institute for System Dynamics and Control Theory SB RAS Lermontov St. 134 Irkutsk Russia 664033

In the paper, we propose a new model of the natural gas market simulation. It takes into account the random nature of the natural gas demand that depends, for example, on temperature fluctuations during the heating period. The natural gas supplier strategy is optimized with the reservation of the necessary amount of fuel to compensate for demand fluctuations. To implement simulation modeling, we developed a scalable application with the DISCOMP framework. We apply DISCOMP to develop and use scalable applications in a heterogeneous distributed computing environment. The application significantly increases the number of model runs and improves the simulation accuracy in comparison with the Mathcad computations on a personal computer.

Scientific Visualization 2017年第2期9卷 102-119页

作者： Korshunov, S.A. Nikolaychuk, O.A. Pavlov, A.I. Matrosov Institute for System Dynamics and Control Theory of Siberian Branch of RAS Irkutsk Russia

The paper describes the main principles of visualization software development, as well as implemented by this software approach, which is based on the use of ontologies to describe both the rendered domain, and the rules of its 3Ddisplaying. This approach allows the user to avoid programming the 3Dscene and describe it in terms of the research area. The paper set out a formal model of a software tool, its architecture, basic modules and ontology structure. The process of visual scene design and creation is described, including the steps of ontology modelling, visual objects creation, formation of scene describing rules, code generation, visualization, organization of data exchange between visualization software and data source. WebGLbased library was chosen as primary means for 3D graphics rendering, which allows to create visual scenes in the user's web browser. Examples of generated scenes and the question of its performance are also discussed in the article.
