GALACTIC AND EXTRAGALACTIC SUPERNOVA REMNANTS AS SITES OF PARTICLE ACCELERATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Supernova remnants, owing to their strong shock waves, are likely sources of Galactic cosmic rays. Studies of supernova remnants in X-rays and gamma rays provide us with new insights into the acceleration of particles to ...
EFFECT OF IMPERATA CYLINDRICA REINFORCEMENT FORM ON THE TENSILE AND IMPACT PROPERTIES OF ITS COMPOSITES WITH RECYCLED LOW DENSITY POLYETHYLENE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Composites of recycled low-density polyethylene obtained from waste water-sachets and imperata cylindrica were produced with particulate and long-fibre unidirectional mat reinforcements. Comparison was made of the tensile ...
UPDATED VERSION OF THE SIMPLIFIED MODEL OF INTENSIVELY BLASTED ELECTRIC ARC
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The article deals with an improvement of a simplified model of intensively blasted electric arc burning in argon in an anode channel of a modular-type arc heater. Gradually gained experience in the application of the model ...
ANALYSIS OF DALLARA T12 RACE CAR FRONT WING VIBRATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
This work investigates aerodynamic elements’ vibrations of high-speed vehicles on the example of the Dallara T12 race car front wing. Made up energy spectrums of wing vibrations for three specific cases arising during ...
THE TIME DIFFERENCE IN EMISSION OF LIGHT AND PRESSURE PULSES FROM OSCILLATING BUBBLES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Oscillations of spark-generated bubbles are studied experimentally. In this work, an attention is paid to the time difference in the radiation of light flashes and pressure pulses from a bubble at the final stages of the ...
Use of thermal analysis for the detection of calcium oxalate in selected forms of plastering exposed to the effects of Serpula lacrymans
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The article discusses the interaction of metabolic products of a wood-destroying fungus of the dry rot species (Serpula lacrymans (Wulfen) P. Karst.) with a commonly used lime mortar. Mortar samples used in the presented ...
Assessment of the effectiveness of lubrication of Ti-6Al-4V titanium alloy sheets using radial basis function neural networks
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The aim of the research presented in this article was to determine the value of the friction coefficient using a simple tribological test and to build an empirical model of friction with the use of radial basis function ...
An Investigation of corrosion of friction welded and post-weld heat-treated AA6061/SiC/graphite hybrid composites
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
The aluminium-based hybrid metal matrix composites have noteworthy applications in sub-sea installations, structures of deep-sea crawlers, submarine parts, engine cylinders, drum brakes etc., as they possess high strength, ...
Utilization of agricultural waste adsorbent for the removal of lead ions from aqueous solutions
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
This work investigated the potentiality of using chemically modified onion skin waste (CMOSW) as an adsorbent for the removal of lead ions (Pb2+) from an aqueous solution. The material properties were characterized using ...
The impact of the air temperature on measuring the zenith angle during the year in the ground layer of the atmosphere for the needs of engineering surveying
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
This paper presents the results of over a year-long experiment dealing with a temperature measurement to calculate the theoretical effect of the atmosphere on the measured zenith angle in engineering surveying. The ...
