The designing of PID controllers is a frequently discussed problem. Many of design methods have been developed, classic (analytical tuning methods, optimization methods etc.) or not so common fuzzy knowledge based methods which are designed to achieve good setpoint following,…

Despite integration of advanced functions that enable Femto Access Points (FAPs) to be deployed in a plug-and-play manner, the femtocell concept still cause several opened issues to be resolved. One of them represents an assignment of Physical Cell Identifiers (PCIs)…

Development of economy based on knowledge in Poland is determined by the market of electronic communication services that is hardly competitive and at the same time in efficient, what is expressed in a low access level tothe broad-band services and…

This calculation is based on calculation of torque components of induction machines. Basic torque components are expanded, using knowledge of machine’s geometry, to the periphery of machine’s rotor. Using Fourier analysis of torque components it is possible to calculate forces…

For the expansion of PLC systems, it is necesssary to have a detailed knowledge of the PLC transmission channel properties. This contribution shortly discusses characteristics of the PLC environment and a classification of PLC transmission channels. A main part is…

Contemporary Next Generation Networks (NGN) are mainly built on the Internet Protocol (IP) and Ethernet. Major challenge for emerging types of wired and wireless IP-based networks is to provide an adequate Quality of Service (QoS) for different services. The quality…

This article takes down the knowledge with determination of criteria weights in the terms of computer software of superconductive materials. This software relieves processing of considerable enters data. The criteria of the weights were determinated by Fuller triangle and Saaty´s…

This paper presents comparison study of two different deblurring methods: Wiener filter and TSVD decomposition. Wiener filter is a method giving the best results when variance of the noise incorporated in blurring process is known a priori. In TSVD decomposition…

This paper introduces the basic knowledge about magnetoelastic torque sensor designed for non-contact measurements. The paper brings results of Institutional project “The development and realization of torque sensor with appropriate equipment.” The optimization of torque sensor working conditions and sensor…

High-speed superexpresses (HSST) developed by Japanese airlines (JAL) are based on the electrodynamics principle of magnetic suspension. The track contains short-circuited coils and interaction between them and superconductive coils in the vehicle produces its suspension. The paper includes a mathematical…
