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 ...
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.
COULOMB SCATTERING IN NON-COMMUTATIVE QUANTUM MECHANICS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Recently we formulated the Coulomb problem in a rotationally invariant NC configuration space specified by NC coordinates xi, i = 1, 2, 3, satisfying commutation relations [xi, xj ] = 2iλεijkxk (λ being our NC parameter). ...
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 ...
PROPOSAL OF NEW OPTICAL ELEMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
A overview of our patented proposals of new optical elements is presented. The elements are suitable for laser pulse analysis, telescopy, X-ray microscopy and X-ray telescopy. They are based on the interference properties ...
THE INFLUENCE OF SIZE FRACTION ON THE COMPRESSIBILITY OF PINE SAWDUST AND THE EFFECTIVENESS CRITERION FOR DENSIFICATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Particulate matter from biomass, e.g. wood sawdust, is very diverse. The basic parameter describing the densification process of particulate matter is its compressibility, quantified by the coefficient of compressibility. ...
SPECIFIC EMISSIONS FROM BIOMASS COMBUSTION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
This paper deals with determining the specific emissions from the combustion of two kinds of biomass fuels in a small-scale boiler. The tested fuels were pellets made of wood and pellets made of rape plant straw. In order ...
LABORATORY EQUIPMENT FOR AUTOTHERMAL REFORMING OF ORGANIC MATTER IN SUPERCRITICAL WATER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The ability of water to dissolve organic substances is very limited. However, its ability to dissolve them changes if pressure and temperature values reach the so-called critical point (p = 22.06MPa, T = 373.95 °C). Fluid ...
EXPERIMENTAL VERIFICATION OF THE STRUCTURAL AND TECHNOLOGICAL PARAMETERS OF THE PKS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
This paper presents the theoretical design for experimental verification of the structural and technological parameters of the Parallel Kinematic Structure. The experimental equipment was developed at the Faculty of ...
NOx PREDICTION FOR FBC BOILERS USING EMPIRICAL MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Reliable prediction of NOx emissions can provide useful information for boiler design and fuel selection. Recently used kinetic prediction models for FBC boilers are overly complex and require large computing capacity. ...
