Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents, copyright statements, title-page or half title-pages, blank pages, venue maps or other general information relating to the conference that was part of the original...
Integrated circuits and devices revolutionized particle physics experiments, and have been essential in the recent discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider at CERN [1,2]. Particles are accelerated and brought into collision at specific interaction points where detectors, giant cameras of about 40 m long by 20 m in diameter, take pictures of the collision...
This paper introduces control algorithm of three-phase seven level cascaded H-bridge operates as voltage source active rectifier. The proposed control strategy combines PI and PR controllers with mathematical model of converter current loop and provide direct current control with voltage balancing. The theoretical conclusions are verified by simulations made for small-scale laboratory prototype.
This paper deals with application of the diakoptic method in analyse of the switched circuits. There are a few methods for assembling of the matrix which is circuit described. Combination diakoptic method which combine the combined transformation method and the decomposition of the reduction formula into the capacitance matrix is described below. A simple illustrative example is given, too.
As there are also graph methods of circuit analysis in addition to algebraic methods, it is clearly possible in theory to carry out an analysis of the whole switched circuit in two-phase switching exclusively by the graph method as well. For this purpose it is possible to plot a Mason graph of a circuit, use transformation graphs to reduce Mason graphs for all the four phases of switching, and then...
This contribution examines the usage of low frequency components (< 5 Hz) in single trial EEG recordings obtained during right index finger movement for classification of reaching and grasping movements. These components contain delta band activity and Movement Related Potentials (MRPs) associated with the movements. Time-frequency development is used to classify the movements using Hidden Markov...
4G networks to utilize Voice over LTE (VoLTE). VoLTE uses similar authentication mechanisms such as HTTP. It is therefore possible that a web client on the mobile device will use for authentication mechanism originally designed for the VoLTE [10]. I.e. to use the AKA mechanism, which uses the UICC (USIM / ISIM). This mechanism authenticates the user to the mobile network. However, Web applications...
The article describes and compares various digital methods for measurement of short delay between fast analogue signals. A brief characterization of measured signals is given in the first chapter. In the second chapter, there are described various measurement methods. In the third chapter, there are compared various versions of each method and in the last chapter, there are the methods compared one...
This paper presents the implementation of the Preisach hysteresis model of a soft magnetic material. The model application is especially useful in the study of transition effects in power transformers like an inrush current or a ferroresonance. The main problem in the use of the Preisach model is to find a suitable weighting function. We considered two basic methods: estimation and systematic derivation...
This paper deals with the facial surface vibration measurement performed by three different methods. Facial vibrations were measured during performing the resonance voice exercises with different shape of vocal tract or with different length of the resonance tube. Vibrations were measured on the upper lip by vibrometer and on the ala of nose by accelerometer. The amplitude of oscillation was also...
Turbine blades suffer vibrations when they rotate inside a turbo machine. The measurement of those vibrations can indicate a problem in the working regime currently in use or can assess the quality of a manufactured rotating part. In order to evaluate the vibratory state of a spinning stage in a turbo machine, the measurement of the tip clearance and the time of arrival of the blades are computed...
