GALACTIC AND EXTRAGALACTIC SUPERNOVA REMNANTS AS SITES OF PARTICLE ACCELERATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Supernova remnants, owing to their strong shock waves, are likely sources of Galactic cosmic rays. Studies of supernova remnants in X-rays and gamma rays provide us with new insights into the acceleration of particles to ... -
Generalized Continuity Equation for Quasi-Hermitian Hamiltonians
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The continuity relation is generalized to quasi-Hermitian one-dimensional Hamiltonians. As an application we show that the reflection and transmission coefficients computed with the generalized current obey the conventional ... -

(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The generators of the algebra gln+1 in the form of differential operators of the first order acting on Rn with matrix coefficients are explicitly written. The algebraic Hamiltonians for matrix generalization of 3−body ... -
GRB INVESTIGATIONS BY ESA GAIA AND LOFT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The possibility of studying GRBs with the ESA Gaia and LOFT missions is briefly addressed. The ESA Gaia satellite to be launched in November 2013 will focus on high precision astrometry of stars and all objects down to ... -
Growth and Physical Structure of Amorphous Boron Carbide Deposited by Magnetron Sputtering on a Silicon Substrate with a Titanium Interlayer
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Multilayer amorphous boron carbide coatings were produced by radiofrequency magnetron sputtering on silicon substrates. To improve the adhesion, titanium interlayers with different thickness were interposed between the ... -
High-Speed Monitoring of Dust Particles in ITER ELMs Simulation Experiments with QSPA Kh-50
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Dust generation under powerful plasma stream impacts has been studied in ITER ELM simulation experiments with QSPA Kh-50 plasma accelerator. Repetitive plasma exposures of tungsten have been performed by 0.25 ms plasma ... -
HIGHLIGHTS FROM THE LHC
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The Large Hadron Collider (LHC) and the two multi-purpose detectors, ATLAS and CMS, have been operated successfully at record centre-of-mass energies of 7 ÷ 8TeV. This paper presents the main physics results from proton–proton ... -
HYBRID SHEARWALL SYSTEM — SHEAR STRENGTH AT THE INTERFACE CONNECTION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Based on a series of alternating, displacement-controlled load tests on ten one-third scale models, to study the behaviour of the interface of a hybrid shear wall system, it was proved that the concept of hybrid construction ... -
ICECUBE OBSERVATORY: NEUTRINOS AND THE ORIGIN OF COSMIC RAYS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The completed IceCube Observatory, the first km3 neutrino telescope, is already providing the most stringent limits on the flux of high energy cosmic neutrinos from point-like and diffuse galactic and extra-galactic sources. ... -
Ignition Features of Plasma-Beam Discharge in Gas-Discharge Electron Gun Operation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The current paper presents the results of experimental researches to determine the mode features of plasma-beam discharge (PBD) generation by an electron beam injected by a low-vacuum gasdischarge electron gun (LGEG) with ... -
In memory of Alois Apfelbeck: An Interconnection between Cayley-Eisenstein-Pólya and Landau Probability Distributions
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The interconnection between the Cayley-Eisenstein-Pólya distribution and the Landau distribution is studied, and possibly new transform pairs for the Laplace and Mellin transform and integral expressions for the Lambert W ... -
Inactivation of Candida albicans by Corona Discharge: The Increase of Inhibition Zones Area After Far Subsequent Exposition
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The cold atmospheric pressure plasma generated by the negative corona discharge has inhibition effect on the microorganism growth. This effect is well-known and it can be demonstrated on the surface of cultivation agar ... -
INFLUENCE OF THE RESULTS OF UHECR DETECTION ON THE LHC EXPERIMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The cosmic ray energy region 1015 ÷ 1017TeV corresponds to LHC energies 1 ÷ 14TeV in the center-of-mass system. The results obtained in cosmic rays (CR) in this energy interval can therefore be used for developing new ... -
Inherited Properties of Effect Algebras Preserved by Isomorphisms
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We show that isomorphism of effect algebras preserves properties of effect algebras derived from effect algebraic sum ? of elements. These are partial order, order convergence, order topology, existence of states and other ... -
Instability Growth Rate Dependence on Input Parameters During the Beam–Target Plasma Interaction
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The two-stream instability without magnetic field is described by the well-known Buneman dispersion relation. For more complicated situations we need to use the Generalized Buneman Dispersion Relation derived by Kulhánek, ... -

Intervals in Generalized Effect Algebras and their Sub-generalized Effect Algebras
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We consider subsets G of a generalized effect algebra E with 0∈G and such that every interval [0, q]G = [0, q]E ∩ G of G (q ∈ G , q ≠ 0) is a sub-effect algebra of the effect algebra [0, q]E. We give a condition on E and ... -
