Rational extension of many particle systems
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In this talk, we briefly review the rational extension of many particle systems, and is based on a couple of our recent works. In the first model, the rational extension of the truncated Calogero-Sutherland (TCS) model is ... -
Recommended procedure for headroom design according to geometric parameters of building structures
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The system of Czech technical standards for geometric accuracy assumes that the designer determines the functional geometric parameters for a specific building. By calculation, he verifies them in the so-called “geometric ... -
Reduction of pavement thickness using a subgrade layer treated by different techniques
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)A range of stabilisers for poor quality subgrade soils have been developed to promote road constructions. Many of them are becoming more popular depending on their effectiveness. The purpose behind this research is to ... -
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 ... -
Stone Topography – Useful Tool in Monuments Restoration Process
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The surface of building stone on historic buildings often bears the original traces of craftsmanship processing. These are an integral part of the visual appearance of the monument and thus its value, which needs to be ... -
Study of surface roughness with MHD and couple stress fluid on porous curved annular plates
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The purpose of this article is to examine the effect of surface roughness on porous curved annular plates lubricated with couple stress fluid in the presence of magnetic field. The MHD-Stochastic Reynolds equation is derived ... -
Swanson Hamiltonian revisited through the complex scaling method
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In this work, we study the non-hermitian PT-symmetry Swanson Hamiltonian in the framework of the Complex Scaling Method. We show that by applying this method we can work with eigenfunctions that are square-integrable both ... -
The engineering performance of eco-friendly concretes containing diatomite fly ash and ground granulated blast furnace slag
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Approximately 10 % of CO2 is emitted from an ordinary Portland cement production. In cement and concrete production, CO2 emissions can be greatly reduced by using Supplementary Cementitious Materials (SCMs). In addition, ... -
Theoretical analysis of the influence of the chevron inclination angle on the thermal performance of a gasket plate heat exchanger
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Different models are applied for an experimental and theoretical determination of the thermal and hydraulic performance of gasket plate heat exchanger. One of the relevant aspects of recent works is the influence of the ... -
Theoretical and experimental study of water vapour condensation with high content of non-condensable gas in a vertical tube
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This article deals with the possibility of separating water vapour from flue gases after oxyfuel combustion using condensation processes. Those processes can generally be described as condensation of water vapour in the ... -
Time-dependent mass oscillators: constants of motion and semiclasical states
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)This work reports the construction of constants of motion for a family of time-dependent mass oscillators, achieved by implementing the formalism of form-preserving point transformations. The latter allows obtaining a ... -
Time-dependent step-like potential with a freezable bound state in the continuum
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In this work, we construct a time-dependent step-like potential supporting a normalizable state with energy embedded in the continuum. The potential is allowed to evolve until a stopping time ti, where it becomes static. ... -
ZnO-Zeolite nanocomposite application for photocatalytic degradation of procion red and its adsorption isotherm
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In this paper, the photocatalytic degradation of procion red dye, one of the most frequently used dyes in the textile industry, was studied. The objective of the research is to study the ZnO-Zeolite nanocomposite application ...
