Analysis of changes in medical images is one of the most important areas of computer use, which ensures the progress of the diagnostic process at the moment. Along with the quality of visualization, automated diagnostic methods are being developed, CADs are being increasingly used. Today, medical imaging is the most common diagnostic tool in modern medical practice. The most relevant areas for the implementation of medical image analysis in connection with the specificity of the objects under study are methods based on mathematical methods for processing input information, for example, on a fractal analysis (analysis of self-similarity of image parts), which can be realized by calculating the fractal dimension and Hurst index. The obtained data in world practice become the basis for creating new algorithms for qualitative analysis and image processing for creating new algorithms.

The results of heat transfer dynamic processes during the breathing are presented. The study is relevant for investigation of health in the extreme conditions of the Arctic. For estimation of this processes the measurement system of temperature, pressure and velocity pulsations in nostrils are developed. It has been shown that for respiratory system diagnostic it is necessary to analyze such dynamic characteristics as the power spectral density and entropy.

This paper presents the trajectory-tracking control of a Vertical Take-off and Landing (VTOL) rotorcraft endowing a two Degrees of Freedom (DoFs) manipulator arm. The research considers endogenous (parametric) and exogenous (external disturbances) uncertainties as lumped disturbance, which is estimated via an Extended-State Observer (ESO). A feedback controller is synthesized through the control Lyapunov Function (CLF) aided by feedforward terms composed of the ESO estimates. The compound system, the rotorcraft, and the manipulator dynamics are mathematically modeled based on the energy-based Euler-Lagrange (EL) formalism. The system’s stability is analyzed within the Input-State Stability (ISS) framework, guaranteeing closed-loop stability for the overall design (controller-ESO-UAV+arm). Results from an extensive simulation stage prove the effectiveness of the proposed control strategy.

Blockchain, which is a new technology of distributed data storage in the form of a chain of blocks, has become one of the most popular topics in the field of information technology for today. Although the term 'blockchain' is often associated with operations in cryptocurrencies (Bitcoin, for example), its application is not limited to this area. The algorithm for automatic confirmation of transactions has already been successfully applied in accounting, postal services, and smart devices. Additionally, people can participate in the confirmation of transactions. This article considers the possibility of using the technology in creating distributed networks of industrial equipment, i.e. creation of a backbone network for cyber-physical production systems. The proposed approach is detailed and discussed with the support of relevant use cases. A number of architectures of support networks based on blockchain technology are proposed, the positive and negative aspects of this approach are considered. © 2018 IEEE.

With the substantial growth of logistics businesses the need for larger and more automated warehouses increases, thus giving rise to fully robotized shop-floors with mobile robots in charge of transporting and distributing goods. However, even in fully automatized warehouse systems the need for human intervention frequently arises, whether because of maintenance or because of fulfilling specific orders, thus bringing mobile robots and humans ever closer in an integrated warehouse environment. In order to ensure smooth and efficient operation of such a warehouse, paths of both robots and humans need to be carefully planned;however, due to the possibility of humans deviating from the assigned path, this becomes an even more challenging task. Given that, the supervising system should be able to recognize human intentions and its alternative paths in real-time. In this paper, we propose a framework for human deviation detection and intention recognition which outputs the most probable paths of the humans workers and the planner that acts accordingly by replanning for robots to move out of the human's path. Experimental results demonstrate that the proposed framework increases total number of deliveries, especially human deliveries, and reduces human-robot encounters. Copyright © 2020, The Authors.

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://***/about/policies/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief. A journal-wide investigation by Elsevier's Research Integrity & Publishing Ethics team identified violations of the journal's policies on conflict of interest related to the submission and review of this paper. Review of this submission was handled by Guest Editor Elena-Niculina Dragoi despite an extensive recent record of collaboration, including co-publication, with two of the paper co-authors (Ceren Karaman, Nevin Erk). In addition, there was a significant increase of citations of papers authored by the Guest Editor and by author Karaman between the original submission and the revised version; 6 papers by Dragoi and 8 by Karaman were added in the revised version of the paper. This compromised the editorial process and breached the journal's policies. The authors disagree with this retraction and dispute the grounds for it.

This paper proposes a new chattering-free Fixed-time Observer-Based Sliding Mode control (FOBSMC) scheme for synchronization of two bilateral teleoperations under unknown time-varying delay. The system is subjected to unknown disturbances which are estimated in a fixed time by utilizing the Disturbance Observer-based SMC scheme. The fixed-time State Observer-based SMC is designed to estimate the unmeasured velocity state, while the position state is assumed to be available. Fixed-time stability method is used to provide the system convergence time independently of initial states. A FOBSMC scheme is first designed for master system of bilateral teleoperation under unknown time-varying delay to track the environmental torque by the human operating torque in the presence of time delay in the communication channel, as well as estimating the unknown disturbances and unmeasured states. A FOBSMC scheme is designed to synchronize slave system to master system in the presence of time delay in the communication channel, as well as estimating disturbances and states. The stability analysis is performed for closed-loop system of combined controller-observer by using Lyapunov theory. The efficacy of the proposed method to fulfill a good transparency and stability under time-varying communication delays is tested by performing numerical simulation in Simulink/MATLAB. © 2020 John Wiley & Sons Ltd.

A globally convergent state observer for multimachine power systems with lossy lines

arXiv 2020年

作者： Bobtsov, Alexey Ortega, Romeo Nikolaev, Nikolay Schiffer, Johannes Department of Control Systems and Robotics ITMO University Kronverkskiy av. 49 Saint Petersburg197101 Russia LSS-Supelec 3 Rue Joliot-Curie Gif-sur-Yvette91192 France Fachgebiet Regelungssysteme und Netzleitechnik Brandenburgische Technische Universität Cottbus Senftenberg Germany

We present the first solution to the problem of estimation of the state of multimachine power systems with lossy transmission lines. We consider the classical three-dimensional "flux-decay" model of the power system and assume that the active and reactive power as well as the rotor angle and excitation voltage at each generator is available for measurement-a scenario that is feasible with current technology. The design of the observer relies on two recent developments proposed by the authors: a parameter estimation based approach to the problem of state estimation and the use of the dynamic regressor extension and mixing technique to estimate these parameters. Thanks to the combination of these techniques it is possible to overcome the problem of lack of persistent excitation that stymies the application of standard observer designs. Simulation results illustrate the performance of the proposed observer. Copyright © 2020, The Authors. All rights reserved.

IFAC-PapersOnLine 2019年第29期52卷 43-48页

The design of an adaptive active flux observer is an open problem, which attracts a lot of scientists from adaptive control and electric drive societies. The design of new observer for the interior permanent magnet synchronous motor is based on the ”linear regression plus gradient search” approach. It is proved that the flux observer provides asymptotic convergence of estimation errors to zero. In comparison with known solutions proposed approach gives improved results with guaranteed performance (monotonicity, convergence rate regulation) and allows to regulate the convergence rate via the selection of the adaptation gains. The main feature of the proposed observer, compared to existing ones, is that it is well defined in all operating modes, improving its robustness properties.
