Conversion of units of length from the Czech state standard to the geodetic baseline Javoriv
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
Modern society cannot do without high quality geospatial data. This need constantly strengthens with the growth of the information society and the emerging cyber society. Validity and quality of geospatial data is strongly ...
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 ...
Application of strut-and-tie models for assessing RC half-joints not complying with current code specifications
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)
The work described is concerned with an investigation of the effectiveness of the use of strut-and-tie models for the structural assessment of half joints. Such elements form a part of many existing bridges which, although ...
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 ...
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 ...
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 ...
MULTILAYER COATINGS Ti/TiN Cr/CrN AND W/WN DEPOSITED BY MAGNETRON SPUTTERING FOR IMPROVEMENT OF ADHESION TO BASE MATERIALS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
The paper deals with evaluation of single and multilayer layer PVD coatings based on Cr and Ti widely used in tool application. Additionally, W and WN based coating which are not so widespread were designed and deposited ...
Estimation of stresses in a massive granite using laser ultra-sonic testing and stress memory effect
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
This paper addresses in-situ stress-estimation methods based on the Kaiser effect. The physical and mechanical properties of granite, diorite, and granodiorite samples selected at different depth intervals of the core ...
Femtosecond laser processing of advanced technical materials
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
Ultra-short pulsed laser ablation may be used for high-precision machining with very low thermal influence on the processed materials. Due to this reason, lasers are increasingly used for processing of advanced materials, ...
FINITE ELEMENT ANALYSIS OF AORTAL BIFURCATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2015)
Arterial bifurcations loaded by internal pressure represent significant stress concentrators. Increased mechanical stress inside arterial wall probably accelerates pathogenic processes at these places. Stress concentration ...
