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 ... -
An innovative iterative approach to solving Volterra integral equations of second kind
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Many scientists have shown great interest in exploring the realm of second-kind integral equations, offering many techniques for solving them, including exact, approximate, and numerical methods. This paper introduces the ... -
Numerical solution for stochastic Volterra-Fredholm integral equations with delay arguments
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)We present a method for computing the stochastic operational matrix of integration to advance the study of stochastic Volterra-Fredholm integral equations (SVFIEs) based on delay arguments. First, the method evaluates the ... -
Dowel bars – reinforcing elements of cement concrete pavements
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Our aim is to analyze the function of reinforcement elements (dowel bars) in cement concrete pavement to highlight the influence of these elements on the service life of the pavement as a whole and to find possible ... -
Tunisian engineers: protagonists of Tunisia’s modernisation. Two key moments: 1956 and 1987
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Engineers have played a key role in Tunisia’s modernisation process during and after its independence. They were crucial in almost all aspects of life. From the beginning of the reformist project, they were close to power ... -
