A COMPACTING PROCESS OF THE EN AW 6060 ALLOY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This study reports on an investigation of factors affect the process of compacting Al chips which are used to direct scrap processing through the forward extrusion method. EN AW 6060 chips of different geometry and types ...
EFFECTS OF INITIAL MOISTURE CONTENT ON THE PRODUCTION AND QUALITY PROPERTIES OF SOLID BIOFUEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
The moisture content of densified biomass is a limit parameter influencing the quality of the solid biofuel. It influences its calorific value, density, mechanical strength and dimensional stability as well as the production ...
CONDENSATION OF WATER VAPOR IN A VERTICAL TUBE CONDENSER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This paper presents an analysis of heat transfer in the process of condensation of water vapor in a vertical shell-and-tube condenser. We analyze the use of the Nusselt model for calculating the condensation heat transfer ...
PYROLYSIS OF BROWN COAL USING A CATALYST BASED ON W–Ni
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Tars from pyrolysis of brown coal can be refined to obtain compounds suitable for fuel production. However, it is problematic to refine the liquids from brown coal pyrolysis, because high molecular compounds are produced, ...
COVARIANT INTEGRAL QUANTIZATIONS AND THEIR APPLICATIONS TO QUANTUM COSMOLOGY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
We present a general formalism for giving a measure space paired with a separable Hilbert space a quantum version based on a normalized positive operator-valued measure. The latter are built from families of density operators ...
ON THE CONSTRUCTION OF PARTIAL DIFFERENCE SCHEMES II: DISCRETE VARIABLES AND SCHWARZIAN LATTICES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
In the process of constructing invariant difference schemes which approximate partial differential equations we write down a procedure for discretizing a partial differential equation on an arbitrary lattice. An open problem ...
EXPERIMENTAL CHARACTERIZATION OF AN OVERDENSE PLASMA IN A COMPACT ION SOURCE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Electron Cyclotron Resonance Ion Sources (ECRIS) are compact plasma-based machines able to feed particle accelerators with high intensity beams of multi-charged ions. ECRIS plasmas are density-limited, since they are ...
The Intriguing Nature of the Cataclysmic Variable SS Cygni
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
The classification of SS Cyg as a dwarf nova (DN), a subclass of the non–magnetic (NM) cataclysmic variable (CV) has been considered by most of the community as well established because of a paper appeared in Nature (Bath ...
A Study of the Properties of Electrical Insulation Oils and of the Components of Natural Oils
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper presents a study of the electrical and non-electrical properties of insulating oils. For the correct choice of an electrical insulation oil, it is necessary to know its density, dynamic viscosity, dielectric ...
X-ray Spectroscopic Characterization of Shock-Ignition-Relevant plasmas
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Experiments with multilayer plastic/Cu targets performed at a PALS laser system aimed at the study of matter at conditions relevant to a shock ignition ICF scheme, and, in particular, at the investigation of hot electrons ...
