Pin Hole Discharge Creation in Na2SO4 Water Solutions
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
This work deals with the diaphragm discharge generated in water solutions containing Na2SO4 as a supporting electrolyte. The solution conductivity was varied in the range of 270 ÷ 750 µScm-1. The batch plasma reactor with ...
Instability Growth Rate Dependence on Input Parameters During the Beam–Target Plasma Interaction
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
The two-stream instability without magnetic field is described by the well-known Buneman dispersion relation. For more complicated situations we need to use the Generalized Buneman Dispersion Relation derived by Kulhánek, ...
Systems of Electronic Overcurrent Protection in Pulse Power Generator Operating on Plasma Load
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)
Schematic peculiarities of pulsed power source and modulator-shaper for working on high instability plasma load are discussed. In its construction should be provided for several levels of overcurrent protection. First of ...
ON TWO WAYS TO LOOK FOR MUTUALLY UNBIASED BASES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Two equivalent ways of looking for mutually unbiased bases are discussed in this note. The passage from the search for d+1 mutually unbiased bases in Cd to the search for d(d+1) vectors in Cd2 satisfying constraint relations ...
DIRAC AND HAMILTON
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Dirac devised his theory of Quantum Mechanics and recognised that his operators resembled the canonical coordinates of Hamiltonian Mechanics. This gave the latter a new lease of life. We look at what happens to Dirac’s ...
LOCAL VELOCITY PROFILES MEASURED BY PIV IN AN VESSEL AGITATED BY RUSHTON TURBINE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
The hydrodynamics and flow field were measured in an agitated vessel using 2-D Time Resolved Particle Image Velocimetry (2-D TR PIV). The experiments were carried out in a fully baffled cylindrical flat bottom vessel 300 ...
INFRARED PHOTOLUMINESCENCE SPECTRA OF PBS NANOPARTICLES PREPARED BY LANGMUIR–BLODGETT AND LASER ABLATION METHODS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
We optimized the optical setup originally designed for the photoluminescence measurements in the spectral range 400‒1100 nm. New design extends the spectral range into the near infrared region 900‒1700 nm and allows the ...
OBLIQUE MAGNETIC FIELDS AND THE ROLE OF FRAME DRAGGING NEAR ROTATING BLACK HOLE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Magnetic null points can develop near the ergosphere boundary of a rotating black hole by the combined effects of strong gravitational field and the frame-dragging mechanism. The induced electric component does not vanish ...
INFLUENCE OF SUBSTRATE THICKNESS ON DIFFUSE COPLANAR SURFACE BARRIER DISCHARGE PROPERTIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
In presented work the influence of dielectric barrier thickness on the parameters of Diffuse Coplanar Surface Barrier Discharge was investigated. The discharge was operated at atmospheric pressure laboratory air. The ...
DEPOSITION CARBON NANOSTRUCTURES BY SURFATRON GENERATED DISCHARGE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)
Carbon nanostructures were deposited by surface wave discharge using various Ar/CH4/ CO2 gas mixture ratios. The morphology was controlled by adjusting of gas concentration and was investigated by scanning electron microscopy ...
