THERMAL AND CHEMICAL EVOLUTIONS OF GALAXY CLUSTERS OBSERVED WITH SUZAKU
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)We studied the properties of the intracluster medium (ICM) of galaxy clusters to outer regions observed with Suzaku. The observed temperature dropped by about ~30% from the central region to the virial radius of the clusters. ... -
Thermal properties of mineral wool insulation recovered from construction and demolition waste
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Mineral wool is one of the most commonly used types of thermal insulation in the European Union at the present, however, it generates massive amounts of waste. From an environmental standpoint, recycling or reuse of ... -
THERMAL-HYDRAULIC ANALYSIS OF IRT-4M IN REACTIVITY INSERTION ACCIDENT AT VR-1 REACTOR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)The paper deals with thermal-hydraulic analysis during reactivity insertion accident, i.e. a step increase of nuclear system reactivity by 0.7 eff, at VR-1 Reactor. The reactor utilizes IRT-4M type of fuel assemblies, and ... -
THERMO-MECHANICAL FATIGUE ANALYSIS OF A STEAM TURBINE SHAFT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)Increasing demands on the flexibility of steam turbines due to the use of renewable energy sources substantially alters the fatigue strength requirements of components of these devices. Rapid start-ups as well as the ... -
THERMO-MECHANICAL MODEL FOR CONCRETE PAVEMENT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)This paper describes a numerical thermo-mechanical model for concrete pavement, implemented in OOFEM software. The thermal part is a heat transfer problem with appropriate initial and boundary conditions (sun irradiation, ... -
THERMO-VISCOELASTIC CHARACTERIZATION OF POLYMER LAMINATE FILMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2016)The investigated material - laminate is intended as a substrate for small electronic components, electrodes and printed circuits, which are processed onto the laminate prior to thermoforming. The placement of the electronic ... -
THERMOCHEMICAL CALCULATIONS USING SERVICEORIENTED ARCHITECTURE IN THE WEB SERVICE FORM
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The subject of this article is the service-oriented architecture utilization in the design and implementation of a web service that is intended to perform selected thermochemical calculations for chemical reactions. Computing ... -
Thermomechanical calculation within the HERA programme
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)HERA (High Burnup Experiments in Reactivity Initiated Accident) is one of the programmes which should replace closed Halden reactor. As the name implies HERA is focused on the tests simulated RIA (Reactivity Initiated ... -
Thin concrete overlays wit carbon reinforcement on deteriorated concrete pavements
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)In many countries, concrete pavements are normally built as Jointed Plain Concrete Pavements. Due to a lack of alternatives, repairing deteriorated concrete pavements usually requires the replacement of the complete pavement ... -
THIN NITRIDE LAYERS AS PERMEATION BARRIERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)Permeation barriers represent one of the crucial fields in materials development for thermonuclear fusion.
