In this work we analyse operation of a services network which is built from processing nodes serving dedicated services and communication links transmitting required information resources. For task executions specific subsets of network resources – so called communication paths – are allocated. Execution of a task in communication paths is disrupted by occurring faults which are eliminated by renewal procedures leading to delays in task completion time or even to task cancellation. One of the method for overcoming the negative effects of the faults is to apply a path reconfiguration mechanism i.e. a redirection of the communication traffic which bypasses the damaged link. We propose a functional-reliability dependability model of the services network which takes into account possible path reconfigurations. We also define a network dependability parameter which evaluates network efficiency by finding the degree of task losses among all the jobs being executed in the network. © Springer International Publishing Switzerland 2015

The paper presents the current state of research on developing a computer-assisted surgical trainer to be used in a minimally-invasive surgery training program. Along with wide adoption of laparoscopic surgery a strong need for systematic training in the field of minimally-invasive surgery has developed. The goal of the described system is to provide surgeons specialising in minimally-invasive operating techniques an objective performance evaluation method and a safe setting for practicing elementary laparoscopic skills.

The scintillation index of the I0-Bessel-correlated beams generated as temporally incoherent superposition of Laguerre-Gaussian modes with different coherence states and different values of the Orbital Angular Momentum (OAM) index on propagation in atmospheric turbulence is reported. The scintillation index is shown to decrease with the increase in the OAM index. © 2015 Optics InfoBase Conference Papers. All rights reserved.

More safe optimal input signals for parameter estimation of linear systems described by ODE

IFIP Advances in Information and Communication Technology

引用

IFIP Advances in Information and Communication Technology 2014年 443卷 267-277页

作者： Rafajlowicz, Ewaryst Rafajlowicz, Wojciech Institute of Computer Engineering Control and Robotics Wroclaw Poland

Our starting point is the ascertainment that D-optimal input signals recently considered by the same authors [12] can be too dangerous for applying them to real life system identification. The reason is that they grow too fast in time. In order to obtain more safe input signals, but still leading to a good estimation accuracy of parameter estimates, we propose a quality criterion that is a mixture of D-optimality and a penalty for too fast growth of input signals in *** derivations are parallel to those in [12] up to a certain point only, since we obtain different optimality conditions in the form of an integral equation. We also briefly discuss a numerical algorithm for its solution. © IFIP International Federation for Information Processing 2014.

Agent approach to network systems dependability analysis in case of critical situations

Advances in Intelligent Systems and Computing

引用

Advances in Intelligent Systems and Computing 2015年 307卷 73-89页

The chapter describes the analysis and discussion of the network systems in case of the critical situation that happens during ordinary work. The formal model is proposed – based on the two types of real sophisticated network systems – with the approach to its modeling based on the system behavior observation. The agent approach to constant network monitoring is given using hierarchical structure. The definition of the critical situation sets are created by reliability, functional and human reasons. The proposed method is based on specified description languages that can be seen as a bridge between system description and an analysis tools. Using a multilevel-agent based architecture the realistic data are collected. Described architecture can be finding as a basis for a tool that can visualize and analyze data, with respect to real parameters. No restriction on the system structure and on a kind of distribution describing the system functional and reliability parameters is the main advantage of the approach. The proposed solution seems to be essential for the owner and administrator of the transportation systems. © Springer International Publishing Switzerland 2015

Deployment of sensors according to quasi-random and well distributed sequences for nonparametric estimation of spatial means of random fields

IFIP Advances in Information and Communication Technology

引用

IFIP Advances in Information and Communication Technology 2014年 443卷 306-316页

作者： Skubalska-Rafajlowicz, Ewa Rafajlowicz, Ewaryst Institute of Computer Engineering Control and Robotics Wroclaw University of Technology Wroclaw Poland

Our aim is to discuss advantages of quasi-random points (also known as uniformly distributed (UD) points [8]) and their sub-class recently proposed by the authors [17] that are well-distributed (WD) as sensors’ positions in estimating the spatial mean. UD and WD s sequences have many interesting properties that are useful both for wireless sensors networks (coverage an and connectivity) and for large area networks such as radiological or environment pollution monitoring *** opposite to most popular parameter estimation approaches, we consider a nonparametric estimator of the spatial mean. We shall prove the estimator convergence in the integrated mean square-error sense. © IFIP International Federation for Information Processing 2014.
