INHIBITION OF CANDIDA ALBICANS GROWTH ON SURFACES TREATED BY DIELECTRIC BARRIER DISCHARGE WITH VARIOUS BARRIERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Discharges generating low temperature plasma at atmospheric pressure have the potential to treat surfaces biologically contaminated by organic matter in a non-destructive manner. We have been studying ways of inhibiting ... -
INITIAL FOLLOW-UP OF OPTICAL TRANSIENTS WITH COLORES USING THE BOOTES NETWORK

It was originally devoted to the study of the optical ... -
INJECTION MOLDING AND STRUCTURAL ANALYSIS IN METAL TO PLASTIC CONVERSION OF BOLTED FLANGE JOINT BY CAE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)Many metal parts in various applications are being replaced by plastic parts. There are several reasons for that depending on actual application - minimize part cost, enhance corrosion resistance, integrating more components ... -
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, ... -
INTEGRAL METHODS FOR DESCRIBING PULSATILE FLOW
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)This paper presents an approximate solution of the pulsatile flow of a Newtonian fluid in the laminar flow regime in a rigid tube of constant diameter. The model is represented by two ordinary differential equations. The ... -
Integration of Autonomous UAVs into Multi-agent Simulation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)In recent years, Unmanned Aerial Vehicles (UAVs) have attracted much attention both in the research field and in the field of commercial deployment. Researchers recently started to study problems and opportunities connected ... -
Integration of the Watcher Telescope into the Sierra Stars Observatory Network – Lessons Learned for GLORIA
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The UCD Watcher robotic telescope is planning to participate in the Sierra Stars Observatory Network (SSON), a US-based organisation that provides astronomical images upon request to subscribing users, who are typically ... -
INTELLIGENT CONTROLLER FOR TRACKING A 14-INCH CELESTRON TELESCOPE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The paper proposes a design of two fuzzy and Proportional-Integral-Derivative (PID) controllers for a position tracking of the 1400 Celestron telescope. The position responses; right ascension and declination in such a way ... -
Intervals in Generalized Effect Algebras and their Sub-generalized Effect Algebras
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We consider subsets G of a generalized effect algebra E with 0∈G and such that every interval [0, q]G = [0, q]E ∩ G of G (q ∈ G , q ≠ 0) is a sub-effect algebra of the effect algebra [0, q]E. We give a condition on E and ... -
INVERTED PENDULUM WITH LINEAR SYNCHRONOUS MOTOR SWING UP USING BOUNDARY VALUE PROBLEM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Research in the field of underactuated systems shows that control algorithms which take the natural dynamics of the system’s underactuated part into account are more energy-efficient than those utilizing fully-actuated ... -
INVESTIGATING THE Ep, i –Eiso CORRELATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)The correlation between the spectral peak photon energy, Ep, and the radiated energy or luminosity (i.e., the “Amati relation” and other correlations derived from it) is one of the central and most debated topics in GRB ... -
INVESTIGATION OF COMPRESSIBLE FLOW THROUGH A TURBINE BLADE CASCADE FOR VARIOUS TRANSONIC FLOW REGIMES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)This paper deals with the numerical simulation of 2D transonic flow through the SE1050 turbine blade cascade at various flow conditions. The first one concerns the design operation with a zero incidence angle involved in ... -
INVESTIGATION OF THE DYNAMIC BEHAVIOUR OF NON-UNIFORM THICKNESS CIRCULAR PLATES RESTING ON WINKLER AND PASTERNAK FOUNDATIONS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The study of the dynamic behaviour of non-uniform thickness circular plate resting on elastic foundations is very imperative in designing structural systems. This present research investigates the free vibration analysis ... -
IS PT-SYMMETRIC QUANTUM THEORY FALSE AS A FUNDAMENTAL THEORY?
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)Yi-Chan Lee et al. claim (cf. Phys. Rev. Lett. 112, 130404 (2014)) that the “recent extension of quantum theory to non-Hermitian Hamiltonians” (which is widely known under the nickname of “PT-symmetric quantum theory”) is ... -
