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 ...
ANALYSIS OF STATIC ANGLE OF REPOSE WITH RESPECT TO POWDER MATERIAL PROPERTIES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
This paper investigates the Angle of Repose (AoR) of powder materials with respect to their morphological and rheological properties. Glass beads, sand, flour and semolina of different particle sizes were used as the ...
THE EFFECT OF THE FILLING RATIO ON THE OPERATING CHARACTERISTICS OF AN INDIRECT DRUM DRYER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
This article investigates the effect of the filling ratio of the indirect rotary dryers on their operating characteristics. For moist biomass drying before combustion, the use of indirect drum dryers heated by a low pressure ...
INFLUENCE OF CHEMICAL POLYMER ADDITIVE ON THE PHYSICAL AND MECHANICAL PROPERTIES OF EXPANDED POLYSTYRENE CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
This research investigated the effect of Renolith chemical polymer additive (RCPA) on the properties of expanded polystyrene (ESP) concrete. Renolith chemical additive is a polymer-based product in a liquid form made up ...
THE INFLUENCE OF THE FIBRES ARRANGEMENT ON HEAT TRANSFER AND PRESSURE DROP OF POLYMERIC HOLLOW FIBRE HEAT EXCHANGERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
Polymeric hollow fibre heat exchangers are the new alternative to common metal heat exchangers. These heat exchangers provide advantages, such as low weight, corrosion resistance, easy shaping and machining. Moreover, they ...
SIMILARITY SOLUTIONS AND CONSERVATION LAWS FOR THE BEAM EQUATIONS: A COMPLETE STUDY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
We study the similarity solutions and we determine the conservation laws of various forms of beam equations, such as Euler-Bernoulli, Rayleigh and Timoshenko-Prescott. The travelling-wave reduction leads to solvable ...
EXTRACTION AND EVALUATION OF OIL FROM GREEN ALGAE CLADOPHORA GLOMERATA BY HEXANE/ETHER MIXTURE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)
The overall aim of this study was to grow green algae Cladophora glomerata, extract oil from it, and characterize the extracted oil to gain insight into its physicochemical properties. The effects of parameters affecting ...
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 ...
