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 ... -
Reduction of torque pulsation in ultralight helicopter transmission
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Usually, 1–2 seats helicopters use piston engines. One of their disadvantages is a significant torque pulsation on the engine shaft. The main reason for such fluctuations is the change in parameters during the engine’s ... -
REDUCTION OF UNCERTAINTIES IN LASER STRIPE MEASUREMENT OF SOLID PARTICLES CONCENTRATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)Laser stripe measurement (LSM) is a relatively novel method for measuring a local concentration of coarse particles in a mixture with fluid. It is based on an analysis of camera records of the laser sheet penetration in ... -
RELATION BETWEEN LEFT VENTRICULAR UNLOADING DURING ECMO AND DRAINAGE CATHETER SIZE ASSESSED BY MATHEMATICAL MODELING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)The flow-dependent left ventricle overload is a well-known complication of the veno-arterial extracorporeal membrane oxygenation in a severe cardiogenic shock, which leads to a distension of the left ventricle and, frequently, ... -
RELATIONSHIP BETWEEN COMPACTING PRESSURE AND CONDITIONS IN PRESSING CHAMBER DURING BIOMASS PRESSING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)In this paper, we will present the impact of the conditions in pressing chambers during the pressing of wooden briquettes. The conditions in pressing chambers can significantly impact the resulting compacting pressure ... -
Remapping and simulation of EFI system for SI engine using piggyback ECU
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Electronic fuel injection (EFI) is a complex system, many parts are connected together from mechanical parts to electronic parts to control the internal combustion engine. It must ensure many different works and the most ... -
Replacing Natural Gas by Biogas — Determining the Bacterial Contamination of Biogas by PCR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)A promising way of using biogas is to upgrade it to natural gas, which is referred to as Substitute Natural Gas (SNG) or biomethane. Biomethane, or biogas, is produced by biological processes of harnessing the ability of ... -
