This paper aims to describe a benchmarking methodology for testing the performance of IP protocols in industrial and control networks with regard to the deployment of Smart Grids. Based on the ITU recommendation and definitions, the paper summarizes the general communication requirements for ICT networks and confronts them with the requirements set out in the standards for specific types of industrial and control network implementations such as electrical power industry, water industry, transport industry, etc. The paper provides qualitative parameters, which aim to characterize the transmission characteristics of IP protocol based on confrontation of the communication requirements. It is necessary to define general data streams that are typical for industrial and control networks and measurement scenarios for measuring these transmission characteristics. Finally, the paper defines the minimum topology of test network and minimal configuration of network elements where the methodology for testing IP protocols is demonstrated.

The EPDB is a set of two Electrical Power Distribution Boxes (EPDB) intended for small utility/commuter aircraft of the CS-23category, powered with two engines from a 28 Vdc electrical power system. EPDB's main function consists in the intelligent management of electrical energy, thus ensuring the distribution of the power from airborne electrical sources to airborne electrical loads. This paper deals with the concept design of the EPDB, describes the basic architecture and considers the regulation aspects.

The contribution deals with sensitivity analysis of a mechatronic system with flexibility and its control using the tool for scientific computation - Matlab. There are different methods of a mechatronic system control design used in this article. The system sensitivity is analysed on the basis of absolute differential (parametric) and relative differential sensitivity. Also, the influence of variability in selected parameters on the shape of step response and frequency-response characteristic is studied.

Technical textile materials can be successfully used also as a protection against external electromagnetic field. There are available technologies to improve the material surface - with use of different (galvanize, plate, etc.) technologies. The paper deals with woven textiles - compound of cotton, polyester and conductive fibers. The paper presents the impact of electromagnetic field on special woven textile materials and describes the shielding principles. The measurement technique used at FEL CTU in Prague is also described and the base measuring technologies are discussed. Nevertheless, the major part of the paper is dedicated to experience of authors with numerical (FE) modeling of shielding textiles and to description of designed and used methodology of FE model evaluation. The numerical results are compared to measurement and to mathematical (Matlab) model results.

Many mechanical systems are characterized by flexible joints. These kinds of systems are often exposed for mechanical oscillations. These objects are represented by cranes, long manipulator's arms or conveyors drives. All these objects can be approximated by multi-mass systems. To avoid the oscillations the input shaper method can be used. The main control strategies are usually based on PID controllers. The paper shows possible structures of interaction between PID controllers and input shaping.

Civilian or military operational centers are typical for their specific set of activities according to solved problems. Operational personnel have to perform procedural as well as positive kind of control of its controlled entities. To help these personnel with their decisions, we propose to build an automated system based on knowledge structure. This paper deals with procedural reasoning multi agent system designed to take over certain kind of task at operational center like firefighting operational center or military air operations center.

This article explores cooperation of different mathematical models in the same system if the Particle Swarm Optimization (PSO) method is used for system parameter identification. Four different realistic system mathematical models of the second order were used to create different state spaces of the agents' positions. All the experiments were evaluated in wide and narrow intervals around the fitness function global minimum with two different PSO method initial agents' setup. Better results can be seen in some special cases when comparing model cooperation to single model optimization.

The most important stress factors for electric machines insulation in the automotive environment can be summarized by the mnemonic expression TEAM (thermal, electrical, ambient, and mechanical stress). Even already each individual of the above mentioned stresses can be fatal for the electric machine insulation they generally act simultaneously making even worse deterioration process and so faster ageing of insulation. In automotive applications, the electrical machines are designed to be smaller and lighter, with increased torque and power to volume ratio and in the same time these machines are often short-term overloaded during driving cycle. The aim of the paper is to estimate the impacts of these short-term over loadings (TEAM stresses) on insulation aging and on electrical machine life time period. After a brief review of the four most influential stresses in automotive environment we propose a method for an accelerated multi-factor stress insulation testing. In conclusion, there is an example how the proposed multi-factor stress ageing model can be integrated into optimization procedure and further into new e-machine lifetime estimator.
