CZECH WW2 CONCRETE FORTIFICATIONS: CORROSION PROCESSES AND REMEDIATION METHOD BASED ON CRYSTALLIZING COATING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Concrete is a relatively new structural material, hence the remediation of concrete structures is very rare. There are a lot of concrete fortifications in the Czech Republic, which were built just before WW2. These bunkers ... -
WAAM TECHNOLOGY OPTIMIZED BY OFF-LINE 3D ROBOT SIMULATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)WAAM (Wire + Arc Additive Manufacturing) is an alternative additive technology that combines an electric arc as a heat source, filler material in the form of a wire for welding and cladding individual weld passes so as to ... -
3D DIGITAL RECONSTRUCTION BASED ON ARCHIVED TERRESTRIAL PHOTOGRAPHS FROM METRIC CAMERAS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)The paper deals with the possibilities and limitations of the image processing of digitalized terrestrial photographs from analogue metric cameras. By the end of the 20th century, analogue metric cameras such as Zeiss UMK ... -
COMMON CROSSING CONDITION MONITORING WITH ON BOARD INERTIAL MEASUREMENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)A railway turnout is an element of the railway infrastructure that influences the reliability of a railway traffic operation the most. The growing necessity for the reliability and availability in the railway transportation ... -
THE CHARACTERISTICS OF Al-Si COATING ON STEEL 22MnB5 DEPENDING ON THE HEAT TREATMENT
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)The coating on the 22MnB5 steel is intended to protect it against oxidation during the forming process. This steel is hot-pressed. A preheating before the pressing and subsequent hardening in the tool affects the properties ... -
MECHANICAL PROPERTIES OF RAMMED EARTH WITH RESPECT TO CLAY MIXTURE COMPOSITION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Unfired earth is a traditional building material, but it is less used than other building materials, such as concrete or steel. But the use of unfired earth is experiencing a renaissance. ammed earth is a type of unfired ... -
A COMPARATIVE STUDY OF DATA-DRIVEN MODELING METHODS FOR SOFT-SENSING IN UNDERGROUND COAL GASIFICATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Underground coal gasification (UCG) is a technological process, which converts solid coal into a gas in the underground, using injected gasification agents. In the UCG process, a lot of process variables can be measurable ... -
HEAT FLUX JUMP METHOD AS A POSSIBILITY OF CONTACTLESS MEASUREMENT OF LOCAL HEAT TRANSFER COEFFICIENTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This article deals with the derivation of the temperature response of the finite thickness wall, which is heated by heat flow, as a possibility to measure the local values of the heat transfer coefficient with a very high ... -
A MULTIPHASE FLOW LOOP DESIGN FOR INVESTIGATING THE PARTIAL PHASE SEPARATION IN A PIPE TEE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This article presents a design and commissioning of a multiphase flow loop, which was developed for scrutinizing the partial phase separation characteristics of pipe Tees. Its length is 9m and its primary diameter is 0.078m ... -
EVALUATING SHEAR STRENGTH OF SAND- GGBFS BASED GEOPOLYMER COMPOSITE MATERIAL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Geopolymer has been emerging as a novel and sustainable replacement for the traditional soil improvement materials, such as ordinary Portland cement OPC and lime, which have severe environmental impacts. In this paper, a ...
