USING THE AUTOMATIC VECTORISATION METHOD IN GENERATING THE VECTOR ALTIMETRY OF THE HISTORICAL VLTAVA RIVER VALLEY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The article describes, in detail, the generation procedure of vector altimetry of an upper and middle course of the Vltava River historical valley. By the historical valley, the shape of the river valley before the ... -
SENSITIVITY ANALYSIS OF INPUT PARAMETERS FOR LOAD CARRYING CAPACITY OF MASONRY ARCH BRIDGES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The article deals with an analysis of railway masonry arch bridges. Typical attributes of these bridges are pointing loss and backfill. Therefore, the material - masonry - behaviour can be described only by a non-linear ... -
EXTERNAL ROLLING OF A POLYGON ON CLOSED CURVILINEAR PROFILE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The rolling of a flat figure in the form of an equilateral polygon on a curvilinear profile is considered. The profile is periodic. It is formed by a series connection of an arc of a symmetrical curve. The ends of the arc ... -
PILE SETTLEMENT INDUCED FROM SOIL MOVEMENT DUE TO BREAKDOWN OF RETAINING WALL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Very few studies measured the settlement of retaining wall supported piles foundation under a soil movement. This study explores the pile settlement induced from the sudden breakdown of a closely located retaining wall ... -
COMPLEXITY REDUCTION OF CYCLOSTATIONARY SENSING TECHNIQUE USING IMPROVED HYBRID SENSING METHOD
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)In cognitive radio system, the spectrum sensing has a major challenge in needing a sensing method, which has a high detection capability with reduced complexity. In this paper, a low-cost hybrid spectrum sensing method ... -
EXPERIMENTAL INVESTIGATION OF THE POZZOLANIC POTENTIALS OF MILLET AND RICE HUSK ASH AS MINERAL ADDITIVE IN SELF-COMPACTING CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Self-compacting concrete (SCC) is a new concept of concrete mix which flows in a formwork and consolidates itself without the need for compaction. Effectively compacting concrete can be very difficult especially in areas ... -
CHAOTISED POLYMERIC HOLLOW FIBRE BUNDLE AS A CROSSFLOW HEAT EXCHANGER IN AIR-WATER APPLICATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Fifteen years ago, polymeric hollow fibre heat exchangers were presented for the first time. Nowadays there are not only the shell-and-tube types as there were at the beginning. In this paper, six chaotised polymeric hollow ... -
DEFORMATION ANALYSIS OF LAYERED REINFORCED CONCRETE - FOAM CONCRETE FLOOR SLABS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)This article presents a theoretical study of a stress-strain state of layered reinforced concrete - foam concrete floor slabs (hereinafter called as the LRFCS), with the use of a deformation analysis. Compressive and tensile ... -
STRUCTURE FROM MOTION PROCESSING OF ANALOGUE IMAGES CAPTURED BY ROLLEI METRIC CAMERA, DIGITIZED WITH VARIOUS SCANNING RESOLUTION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)SfM processing of archived analogue images gives an opportunity to efficiently create new and valuable 2D and 3D results. The SfM processing of digitized analogue images brings some challenges. How to digitize negatives ...
