3D printing turns digital 3D models into solid objects by building them up in layers. The technology was first invented in the 1980s, and since that time has been used for rapid prototyping. Currently, it is possible to 3D ...
It is considered in this paper an opportunity to develop a permanent magnet synchronous motor (PMSM) vector control system with desired quality. A model reference adaptive control (MRAC) system based on hyper-stability theory ...
In this paper the possibilities for application of the variational approach for analysis of transient processes in linear and non-linear electric circuits are presented. It is based on two basic theorems, which were introduced ...
Software-Defined Networks is a brand new network concept that changes the way networks operate. In order to satisfy the network performance there are some issues that needs to be considered. Finding the best controller location ...
This paper presents a method for graph topology evaluation based on the Spectral graph theory, which is based on the analysis of Eigen values and Eigen vectors of the graph matrices. When doing Spectral graph analysis, the ...
This paper examines the payment of pensions in terms of the monopoly extent, rates of liberalization, competition and EU legislation in the field of services of general economic interest. The necessity of the obligation to ...
In this paper we present outdoor propagation of wireless sensor nodes in different scenarios. We observe some cases in which we measure Received Signal Strength (RSS) and then by calculations we find the Path Loss (PL) of ...
