Emittance Characterization of Ion Beams Provided by Laser Plasma
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Laser ion sources offer the possibility to obtain ion beams useful for particle accelerators. Nanosecond pulsed lasers at intensities of the order of 108 W/cm2, interacting with solid matter in a vacuum, produce plasma of ... -
Emmy Noether and Linear Evolution Equations
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)Noether’s Theorem relates the Action Integral of a Lagrangian with symmetries which leave it invariant and the first integrals consequent upon the variational principle and the existence of the symmetries. These each have ... -
EMPLOYMENT, PRODUCTION AND CONSUMPTION WITH RANDOM UPDATE: NON-EQUILIBRIUM STATIONARY STATE EQUATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)In this work, we investigate the Model of Employment, Production and Consumption, as introduced in a series of papers by I. Wright [1–3] from the perspective of statistical physics, and we focus on the presence of equilibrium. ... -
Energetic Approach to Large Strain Gradient Crystal Plasticity
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)We formulate a problem of the evolution of elasto-plastic materials subjected to external loads in the framework of large deformations and multiplicative plasticity. We focus on a spontaneous inhomogenization interpreted ... -
Energy Accumulation by Hydrogen Technologies
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)Photovoltaic power plants as a renewable energy source have been receiving rapidly growing attention in the Czech Republic and in the other EU countries. This rapid development of photovoltaic sources is having a negative ... -
ENERGY EFFICIENCY OF PLANAR DISCHARGE FOR INDUSTRIAL APPLICATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)Diffuse Coplanar Surface Barrier Discharge has proven its capabilities as an industry-ready plasma source for fast, in-line and efficient plasma treatment at atmospheric pressure. One parameter required by industry is ... -
Energy Estimation of Distributed Phase-shift Beamforming
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)Ad-hoc and sensor networks are composed of small, low-power devices, which can connect between themselves without the help of an infrastructure. Research in this area has been both extensive and intensive and is still very ... -
