LOW-MASS BINARY X-RAY SOURCES: MONITORING WITH VARIOUS SATELLITES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We show the importance of observing low-mass binary (LMXB) X-ray sources with the X-ray monitors onboard satellites. This enables us to study the physical processes governing the longterm activity of LMXBs. They are excellent ... -
ON OBSERVATIONAL PHENOMENA RELATED TO KERR SUPERSPINARS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We investigate possible signatures of a Kerr naked singularity (superspinar) in various observational phenomena. It has been shown that Kerr naked singularities (superspinars) have to be efficiently converted to a black ... -
OPTIMIZING THE WELDING OF PLASTICS WITH THE USE OF DIFFERENTIAL SCANNING CALORIMETRY AND THERMOGRAVIMETRIC ANALYSIS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Plastics have different thermal stability, depending on the structure of the polymer chains. It is therefore very important to know their thermal properties, which influence the temperature regime of processing equipment. ... -
PHOTOMETRIC ANALYSIS OF PI OF THE SKY DATA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Pi of the Sky is a system of two wide field of view robotic telescopes, which search for short timescale astrophysical phenomena, especially for prompt optical GRB emissions. The system was designed for autonomous operation, ... -
“PI OF THE SKY” OFF-LINE EXPERIMENT WITH GLORIA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)GLORIA is the first free and open-access network of robotic telescopes in the world. Based on the Web 2.0 environment, amateur and professional users can do research in astronomy by observing with robotic telescope, and/or ... -
SEGMENTING TAGGED CARDIAC MRI DATA USING A LOCAL VARIANCE FILTER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)We present a new method for segmenting tagged MRI data. It is based on the observation that the tagging grid vanishes almost immediately inside the ventricles because of the blood flow. Segmentation can be therefore driven ... -
STATIC TESTS OF UNCONVENTIONAL PROPULSION UNITS FOR ULTRALIGHT AIRPLANES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)This paper presents static tests of a new unconventional propulsion unit for small aviation airplanes. Our laboratory stand – a fan drive demonstrator – enables us to compare various design options. We performed experiments ... -
STIRRED FLUIDIZED-BED DRYER OF REGENERATED ION EXCHANGER PARTICLES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)This article describes intensification of the fluidized-bed drying process for regenerated spherical-shape ion exchanger particles in the batch mode, achieved by a mechanical stirrer in the fluidized bed layer of the dried ... -
X-RAY TRANSMISSION AND REFLECTION THROUGH A COMPTON-THICK MEDIUM VIA MONTE-CARLO SIMULATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)The spectral shape of an X-ray source strongly depends on the amount and distribution of the surrounding material. The spectrum of a primary source which is located in an optically thin medium with respect to Compton ...
