Investigation of the effect of elbow pipes of Ti6Al4V, 304 stainless steel, AZ91 materials on erosion corrosion by finite element analysis
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Corrosion is the degradation of metals caused by chemical or electrochemical reactions with their environment. As a result of these reactions, undesirable conditions occur in the physical, chemical, mechanical and electrical ... -
Optimised rotating energy-efficient clustering for wireless sensor devices by sewing training-based optimisation
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Wireless sensor networks (WSNs) have become well-known as innovative, active, and robust technology accepted in many real-world applications. Due to the power supply restrictions and the power limitations of sensors that ... -
Hydrothermal and mechanical performance of mortars containing waste brick powder
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)It is widely recognised that green building, environmental sustainability, and technical performance have recently become requirements in the field of civil engineering. For this reason, the new trend in research is to ... -
Effect of surface area on the wear properties of Al-based automotive alloy and the role of Si at eutectic level
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The efficiency of an engine material is closely correlated with its surface area. In order to investigate wear properties, effect of surface contact area as well as silicon addition at the eutectic level of Al-Cu-Mg alloy ... -
Investigation the plastic flows in the metal stamping-drawing process at the die corner
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The present investigation covers the study of the influence of metal-plastic flow on the die corner for the deformed state of the blank and energy-power parameters during stamping-drawing. The influence of workpiece size ... -
Non-homogeneity effect on the vibration of the rectangular visco-elastic plate subjected to the linear temperature effect with quadratic thickness variation in both directions
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The present work investigates the effect of non-homogeneity on the vibration of a rectangular visco-elastic plate. The plate is subjected to linear temperature variation in the x-direction with quadratic thickness variation ... -
Experimental investigation of an entropy production in a linear blade cascade
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The vortical structures in turbomachinery are crucial phenomena that significantly impact the machine’s efficiency. Therefore, investigating them is essential for a better understanding of the machine’s operation.The ... -
The load-transfer method as a tool for determining the load-displacement curve of piles
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The paper presents two applications (software packages) in which the load-transfer method is used for axially loaded Kelly drilled bored piles and displacement ductile iron piles. In the first, the ultimate friction is ... -
so(3) ⊂ su(3) revisited
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This paper reproduces the result of Elliot, namely that the irreducible finite dimensional representation of the Lie algebra su(3) of highest weight (m, n) is decomposed according to the embedding so(3) ⊂ su(3). First, a ... -
A new structural reconfiguration for multilevel inverters with fault tolerance capability
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Keeping electrical systems running is critical in industries especially in those that rely on static converters, for example in the case of inverters, continuous and safe of operation must be ensured even if one of the ...
