Quantum description of angles in the plane
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
The real plane with its set of orientations or angles in [0, π) is the simplest non trivial example of a (projective) Hilbert space and provides nice illustrations of quantum formalism. We present some of them, namely ...
Analytic and Algebraic Methods in Physics

A comparative study of ferrofluid lubrication on double-layer porous squeeze curved annular plates with slip velocity
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This article makes an effort to present a comparative study on the performance of a Shliomis model-based ferrofluid (FF) lubrication of a porous squeeze film in curved annular plates taking slip velocity into account. The ...
Performance of a hydromagnetic squeeze film on a rough circular step bearing: a comparision of different porous structures
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This investigation deals with a comparative analysis of the impact of spongy structure based on the model of Kozeny-Carman and Irmay on a hydromagnetic squeeze film in a rough circular step bearing. Christensen and Tonder’s ...
Analysis of output voltage ripple for dual randomized PWM buck converter operating in continuous and discontinuous conduction modes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
Dual Randomized Pulse Width Modulation (DRPWM) is renowned for its better effectiveness than Simple Randomized Pulse Width Modulation (SRPWM) in reducing conducted Electro-Magnetic Interferences (EMI) in power converters. ...
CFD modelling of a secondary settling tanks: generalization based on database relations
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
The modelling of a secondary settling tank area using numerical methods has been quite extensively explored and researched by numerous authors and papers. These developed models utilize different approaches, from efforts ...
A model of isotope transport in the unsaturated zone, case study
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This work deals with a groundwater flow and solute transport model in the near-surface (predominantly unsaturated) zone. The model is implemented so that it allows simulations of contamination transport from a source located ...
Effect of pigments on bond strength between coloured concrete and steel reinforcement
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
The effect of pigments on mechanical properties of coloured concrete intended for structural applications, including the bond stress-slip behaviour to embedded steel bars, is not well understood. Series of concrete mixtures ...
Results of research on backlash compensation in a power electric drive by low-power electronic device
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This article considers the feasibility of restoring and maintaining the kinematic accuracy of the support-rotary device drives by introducing a backlash compensation device into the control system. The power electromechanical ...
Functional aerodynamics and its influence on the energy and thermal mode of a naturally ventilated double-skin transparent façade
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
This article deals with the dynamics of airflow through a cavity. In windless conditions, where a natural flow causes the flow of air in the cavity, the overall aerodynamic resistance of the cavity is the important aerodynamic ...
