EFFECT OF TUBE PITCH ON HEAR TRANSFER IN SPRINKLED TUBE BUNDLE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Water flowing on a sprinkled tube bundle forms three basic modes: the Droplet mode (the liquid drips from one tube to another), the Jet mode (with an increasing flow rate, the droplets merge into a column) and the Membrane ...
CHANGES IN THE SURFACE LAYER OF ROLLED BEARING STEEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
This paper describes changes observed in bearing steel due to roller burnishing. Hydrostatic roller burnishing was selected as the most suitable method for performing roller burnishing on hardened bearing steel. The ...
COMPARISON OF MATHEMATICAL MODELS FOR HEAT EXCHANGERS OF UNCONVENTIONAL CHP UNITS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
An unconventional CHP unit with a hot air engine is designed as the primary energy source with fuel in the form of biomass. The heat source is a furnace designed for combustion of biomass, whether in the form of wood logs ...
ON PARTIAL DIFFERENTIAL AND DIFFERENCE EQUATIONS WITH SYMMETRIES DEPENDING ON ARBITRARY FUNCTIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
In this note we present some ideas on when Lie symmetries, both point and generalized, can depend on arbitrary functions. We show a few examples, both in partial differential and partial difference equations where this ...
APPLICATION OF DIMENSIONAL ANALYSIS IN HEAT LOSS DETERMINING IN DISTRICT HEATING SYSTEMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
Existing procedures for determining the heat loss in heat distribution use balance relations, or rather they are based on the theory of heat and mass transfer. Dimensional analysis enables a new point of view that demonstrated ...
ON CUBATURE RULES ASSOCIATED TO WEYL GROUP ORBIT FUNCTIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
The aim of this article is to describe several cubature formulas related to the Weyl group orbit functions, i.e. to the special cases of the Jacobi polynomials associated to root systems. The diagram containing the relations ...
Optimization of Fuzzy Logic Controller for Supervisory Power System Stabilizers
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper presents a powerful supervisory power system stabilizer (PSS) using an adaptive fuzzy logic controller driven by an adaptive fuzzy set (AFS). The system under study consists of two synchronous generators, each ...
Teaching Management at Technical Universities Business Reality in the Academic Environment
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Students of technical universities often do not understand why their studies should include learning management skills (in addition to the study of economics). However, not only the experience of graduates but also the ...
Modeling of Concrete Creep Based on Microprestress-solidification Theory
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Creep of concrete is strongly affected by the evolution of pore humidity and temperature, which in turn depend on the environmental conditions and on the size and shape of the concrete member. Current codes of practice ...
Angular Distribution of GRBs
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
We studied the complete randomness of the angular distribution of BATSE gamma-ray bursts (GRBs). Based on their durations and peak fluxes, we divided the BATSE sample into 5 subsamples (short1, short2, intermediate, long1, ...
