This book, dedicated to Professor Georgi M. Dimirovski on his anniversary, contains new research directions, challenges, and many relevant applications related to many aspects within the broadly perceived areas of systems and control, including signal analysis and intelligent systems. The project comprises two volumes with papers written by well known and very active researchers and practitioners. The first volume is focused on more foundational aspects related to general issues in systems science and mathematical systems, various problems in control and automation, and the use of computational and artificial intelligence in the context of systems modeling and control. The second volume is concerned with a presentation of relevant applications, notably in robotics, computer networks, telecommunication, fault detection/diagnosis, as well as in biology and medicine, and economic, financial, and social systems too.

This paper presents a new template matching algorithm in which the central moments are used as the matching features and the idea of integral image are used to decrease the time for image matching process. The algorithm also combines coarse-fine two-stage searching methods to effectively solve the problem of finding the peak point of the correlation functions accurately and robustly. It is different with traditional methods in which pixels are used as matching features. Experiment results show that the image process procedure can be finished within 40 ms, which is the rate of image signal send from TV camera for real time object tracking. The results has broad applications in the fields of real time moving object tracking, pattern recognition and the machine vision, etc.

The governing equations are the Navier-Stokes equations for viscous calorically perfect gas. Second order finite volume discretization is applied to the problem on arbitrary unstructured grids with implicit temporal treatment. The problem is solved using the Newton-Raphson method. Such methods require the solution of large linear systems with iterative solvers and require a preconditioning operator to converge. In this paper a well known Lower-Upper Symmetric Gauss Seidel (LU-SGS) preconditioner is applied. The new method is based on the tricky reordering for the factored Jacobi matrix that allows one to execute block triangular matrix solvers on GPUs in parallel without the loss of algebraic properties of the original non-factored operator. Good convergence properties are demonstrated for large scale problems of external aerodynamics with Courant number around 1000 - 10000 for flows with Mach number around 13-25. The influence of the non-orthogonal corretions on the fluxes for highly scewed anisotropic grids is demonstrated at Mach numbers around 20. It is shown that the non-orthogonality corrections are of the second infinitesimal order compared to the effects of the shock fix influence on the heat fluxes on the body. © 2020 Institute of Physics Publishing.

Today, the operating TAIGA (Tunka Advanced Instrument for cosmic rays and Gamma Astronomy) experiment continuously produces and accumulates a large volume of raw astroparticle data. To be available for the scientific community these data should be well-described and formally characterized. The use of metadata makes it possible to search for and to aggregate digital objects (e.g. events and runs) by time and equipment through a unified interface to access them. The important part of the metadata is hidden and scattered in folder/files names and package headers. Such metadata should be extracted from binary files, transformed to a unified form of digital objects, and loaded into the catalog. To address this challenge we developed a concept of the metadata extractor that can be extended by facility-specific extraction modules. It is designed to automatically collect descriptive metadata from raw data files of all TAIGA formats. © 2019 CEUR-WS. All rights reserved.

On the inversion of multiple matrices on GPU in batched mode

Supercomputing Frontiers and Innovations 2018年第2期5卷 23-42页

作者： Evstigneev, Nikolay M. Ryabkov, Oleg I. Tsatsorin, Eugene A. Federal Research Center 'Informatics and Control' Institute for System Analysis Russian Academy of Science Moscow Russia Lomonosov Moscow State University Moscow Russia

In this research we are considering the benchmarking of batched matrix inversion and solution of linear systems. The problem of multiple matrix inversion with the same fill sparsity is usually considered in problems of fluid mechanics with chemistry. In this case the system is stiff, and an implicit method is required to solve the problem. The core of such method is the multiple matrix inversion. We benchmark different methods based on cuSPARSE and MAGMA libraries and CPU LAPACK version depending on the matrix filling. We also provide our own experimental code that implements GaussJordan elimination on GPU using register shuffle. It is shown that the fastest method is the QR matrix inversion for single precision calculations. We also show that the suggested Gauss-Jordan elimination method looks promising being about 8-10 times faster than cuSPARSE QR method. We also demonstrate the application of batch solvers in the coupled reactive flow problem. © The Author 2018.

The subscription language is an important design decision for distributed event notification services (DENS). In order to minimize resource consumption and enable applications to use rich and complex subscription languages only when they are really needed, we have developed a DENS that separates the concerns of delivering subscriptions and notifications from the subscription specification and event filtering, i.e., the subscription language. To resolve the conflict between subscription language independence in DENS and a strict decoupling of publishers and subscribers through the DENS, we request that for each new subscription language three language specific plug-ins are provided. In this paper, we present the technical details of this solution and describe our proof-of-concept implementation that supports a simple attribute-value based subscription language and a fuzzy concept-based language.

The aim of SETH is to give end-users specific advice concerning treatment and monitoring of adult drug poisoning. SETH is developed with an off the shelf expert system shell (KBMS) and runs on a microcomputer. Technical choices were done according to this analysis, financial considerations and portability. Currently, the database contains 1000 French drugs from 75 different toxicological classes. The SETH expert system simulates the expert reasoning, taking into account for each toxicological class delay, signs and dose. Two phases of evaluation were performed. The experimental implementation of Seth began in April 1992 in our Poison control Centre. Since then, 1100 cases inputted by residents were analysed by SETH. The extension of the knowledge base to child poisoning began in March 1993.

To create a platform for the Marine IoT for ensuring the interaction and digital navigation of heterogeneous marine robotic agents, it is necessary to combine into one network heterogeneous robotic agents, active and passive means of communication and illumination of the underwater and surface environment (marine communication buoys, underwater sonar stations, coastal connection posts). For their joint work, it is necessary to create a communication system unifying all elements of the platform, an integrated navigation and information management system for solving complex problems of navigation and motion control of robotic agents included in the platform to implement a joint mission. To do this, it is necessary to define the architecture of the platform to use a unified approach to data exchange.

The paper proposes an approach to position-force control in the underwater vehicle-manipulator systems. There are two different strategies to realize position-force control systems: through a decoupled or coupled controller. The first one is more flexible and is used in the present article as a PID-controllers array. The paper considers the generalized system design methodology applicable to control objects of any kinematic structure. Compensation blocks for manipulator disturbances and calculation of additional end-effector offset to maintain a constant force on the operating point are proposed. The system also utilizes the desired underwater vehicle position calculation based on the relativity of the vehicle position and operating point for a heading set point. The modeling results showed that the system is able to perform qualitatively force operations in a given point of the working space. In addition, the graphs revealed the compensator unit efficiency and confirmed the necessity of the additional offset calculation unit.
