On an Algorithm for Multiperiodic Words
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We consider an algorithm by Tijdeman and Zamboni constructing a word of length k thathas periods p1, . . . , pr, and the richest possible alphabet. We show that this algorithm can be easilystated and its correctness briefly ... -
ON RENORMALIZATION OF POISSON–LIE T-PLURAL SIGMA MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Covariance of the one-loop renormalization group equations with respect to Poisson–Lie T-plurality of sigma models is discussed. The role of ambiguities in renormalization group equations of Poisson–Lie sigma models with ... -
On Some Statistical Properties of GRBs with Measured Redshifts Having Peaks in Optical Light Curves
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We studied the subset of optical light curves of gamma-ray bursts with measured redshifts and well-sampled R band data that have clearly detected peaks. Among 43 such events, 11 are promptoptical peaks (P), coincident with ... -
On the Solvability of Some Partial Differential Inequality
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The Dulac criterion is a classical method for ruling out the existence of periodic solutions in planar differential equations. In this paper the applicability and therefore reversibility of this criterionis under consideration. -
OPERA HIGHLIGHTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The OPERA experiment is a long baseline neutrino oscillation experiment aimed at observing the νμ → ντ neutrino oscillation in the CERN neutrino to Gran Sasso beamline in the appearance mode by detecting the τ-decay. Here ... -
OUR GALACTIC CENTER – THE NEAREST BURNING DISK
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)This short presentation will update my more than 25 years long attempts at understandingthe actions of the Central Engine at our Galactic Center. -
Particle Dynamics in the RMP Ergodic Layer under the Influence of Edge Plasma Turbulence
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The complex processes in edge tokamak plasma are affected (among others) both by resonant magnetic perturbation (RMP) and by plasma turbulence. RMP is nowadays considered to be a candidate for the mitigation of the ... -
Photometric Analysis of Pi of the Sky Data
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Two fully automatic Pi of the Sky detectors with a large field of view, located in Spain (INTA) and in Chile (SPDA) observe the sky in search of rare optical phenomena, and also collect observations which include many kinds ... -
Physical and Electrical Properties of Yttria-Stabilized Zirconia Thin Films Prepared by Radio Frequency Magnetron Sputtering
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)This paper presents the electrophysical characteristics of a 7 mol.% yttria-stabilized zirconia (YSZ) thin film deposited by radio-frequency magnetron sputtering. In order to form the crystallinestructure, the deposited ... -
Pin Hole Discharge Creation in Na2SO4 Water Solutions
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)This work deals with the diaphragm discharge generated in water solutions containing Na2SO4 as a supporting electrolyte. The solution conductivity was varied in the range of 270 ÷ 750 µScm-1. The batch plasma reactor with ... -
Plasma–Surface Interactions Under High Heat and Particle Fluxes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The plasma-surface interactions expected in the divertor of a future fusion reactor are characterized by extreme heat and particle fluxes interacting with the plasma-facing surfaces. Powerful linear plasma generators are ... -
POPULATION OF BLACK HOLES IN THE MILKY WAY AND IN THE MAGELLANIC CLOUDS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In this review, I will briefly discuss the different types of black hole (BH) populations (supermassive, intermediate mass and stellar mass BHs) both in the Galaxy and in the Magellanic Clouds and compare them with each other. -
Positioning of the Precursor Gas Inlet in an Atmospheric Dielectric Barrier Reactor, and its Effect on the Quality of Deposited TiOx Thin Film Surface
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Thin film technology has become pervasive in many applications in recent years, but it remains difficult to select the best deposition technique. A further consideration is that, due to ecological demands, we are forced ... -

The apparatus was designed to conduct precision studies of charged cosmic radiation over a wide energy range, from tens of MeV up to ... -
Predictive Models in Diagnosis of Alzheimer’s Disease from EEG
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The fluctuation of an EEG signal is a useful symptom of EEG quasi-stationarity. Linear predictive models of three types and their prediction error are studied via traditional and robust measures. The resulting EEG ... -
