AN EXPERIMENTAL ASSESSMENT OF THE PLATE HEAT EXCHANGER CHARACTERISTICS BY WILSON PLOT METHOD
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
An aim of this paper is suggestion of the evaluation method based on the experimental data and the Wilson plot method for the Plate Heat Exchangers (PHE). For the purpose of the project the new experimental loop was built ...
A METHOD FOR MEASURING THE SENSITIVITY OF BUILDING STRUCTURAL MEMBERS TO FIRE DECAY PHASES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
Firefighters face a major threat when intervening in a building during a fire: the possibility of structural collapse during the cooling phase of the fire, or soon thereafter. At present, this threat is amplified by the ...
OPTIMALIZATION OF AFTERBURNER CHANNEL IN BIOMASS BOILER USING CFD ANALYSIS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)
This contribution presents the results of parametrical studies focused on the mixing process in a small rectangular duct within a biomass boiler. The first study investigates the influence of a local narrowing located in ...
Structural Variability of 3C 111 on Parsec Scales
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
We discuss the parsec-scale structural variability of the extragalactic jet 3C111 related to a major radio flux density outburst in 2007. The data analyzed were taken within the scope of the MOJAVE, UMRAO, and F-GAMMA ...
The Optical Transient Search in the Bamberg Southern Sky Survey: Preliminary Results
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
A large fraction of gamma-ray bursts temporarily emit optical light, i.e. optical afterglows and optical transients. So far, optical transients have only been detected after related gamma-ray satellite detection. However, ...
BOOTES Observation of GRB 080603B
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
We report on multicolor photometry of long GRB080603B afterglow from BOOTES-1B and BOOTES-2. The optical afterglow has already been reported to present a break in the optical lightcurve at 0.12 ± 0.2 days after the trigger. ...
Ultra Low Dispersion Spectroscopy with Gaia and Astronomical Slitless Surveys
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
The ultra-low dispersion spectroscopy to be applied in the ESA Gaia space observatory and the ground-based objective-prism plate surveys represent a similar type of astrophysical data. Although the dispersion in plate ...
S5 1803+78 Revisited
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
We report on our optical monitoring of the BL Lac object S5 1803+78 from 1996 to 2011. The source showed no clear periodicity, but a time scale of about 1 300 days between major flares is possibly present. No systematic ...
On the Relation Between GRB Classes and Xray Flashes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
Gamma-ray bursts are usually classified into either short-duration or long-duration bursts. Going beyond the short-long classification scheme, it has been shown on statistical grounds that a third, intermediate population ...
Advanced Functions of a Modern Power Source for GMAW Welding of Steel
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
This paper evaluates the use of a modern welding power source equipped with advanced arc control functions. At the Laboratory of Welding Technologies of CTU in Prague we have focused on GMAW welding of steel using Sigma ...
