We have focused on the investigation of the impact of Ce, Eu, Tm, Eu2O3 and Tm2O3 addition in LPE growth process on the properties of InP layers in the context of their application in detector structures.

The paper describes the possibilities of genetic algorithm application by the reactive power flows’ optimization in Slovak power transmission system. The methods of reactive power flow calculation and the utilization of genetic algorithms for their minimalization are indicated in the…

The article presents one of the methods of location (DCM), which is suitable for using in urban environments, where other methods are less accurate. The principle of this method is in comparison of measured samples of signal with samples stored…

Ceramics materials infringe human life from early years of the humankind. Together with the progress of the science and engineering, various materials and technologies have been used. Suitable materials and technologies have been used in the proper applications. This paper…

The article presents a method of calculating efficiency of squirrel-cage induction motor. This efficiency depends on frequency of the voltage supplied to the motor and on electrical power. Results of laboratory testing of the motor's efficiency are presented.

This paper introduces experiment of 3D reconstruction NMR images scanned from magnetic resonance device. There are described methods which can be used for 3D reconstruction magnetic resonance images in biomedical application. The main idea is based on marching cubes algorithm. For…

In this paper a fuzzy logic based fault diagnosis system for a deaerator in a power plant unit is presented. The system parameters are obtained using the linearised state space deaerator model. The fuzzy inference system is created and rule…

Operation states analysis of a series-parallel converter working above resonance frequency is described in the paper. Principal equations are derived for individual operation states. On the basis of them the diagrams are made out. The diagrams give the complex image…

Oscillations of an elastic two-mass system with all known parameters may be suppressed by suitable feedback signal. An observer enables to estimate this feedback without measurement of load mechanism speed. This article contains application of genetic algorithms for identification of…

The conditions under which breakdown of composite liquid - solid insulation can be occurred, e.g. in transformer, play an important role in designing of such insulation. The initial state of breakdown development is explained based on development of streamers in…
