A novel approach to nonlinear fractional volterra integral equations
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Nonlinear Fractional Volterra integral equations (FVIEs) of the first kind present challenges due to their intricate nature, combining fractional calculus and integral equations. In this research paper, we introduce a novel ... -
Optimising load transfer using temporary supports in monolithic construction
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)When constructing a ceiling slab, it is essential that the load is effectively transferred to the lower floors. However, challenges arise when the lower ceiling slabs do not meet the specified design strengths, potentially ... -
The effect of a malfunctioning braking system on the behaviour of a special vehicle during an emergency braking in a curvilinear movement
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Vehicle mobility is an increasingly important issue today, even in the military field. Mobility depends on the condition of the vehicle, the route and, of course, the experience of the driver. Vehicle failures and damage ... -
Modelling and analysis of three-dimensional chemically reacting, radiating Casson-nanofluid flow: thermophoresis and Brownian motion effects
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)In the presence of a porous material and a magnetic field, the authors of this work must evaluate the combined effects of chemical reaction and thermal radiation on a Casson-nanofluid flow in three dimensions towards a ... -
Acoustic Radiation Patterns of Different Polygon Piston Surfaces
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Transducers are used in acoustic remote sensing and several other modern applications. The radiating surface geometry of a single acoustic transducer affects its beam pattern and has a cumulative effect on the overall ... -
The application of 3D printing technology in the design of sandwich panels
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Composite materials including sandwich panels can offer a number of advantages such as excellent strength to mass ratio or stiffness to mass ratio. Sandwich panels can find their application in many industrial sectors where ... -
Study of non-stationary cutting processes in power skiving
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The paper presents the results of the modelling and study of the cutting process in the cut-in phase during the machining of external gears by the power skiving. The studies were carried out on the basis of the previously ... -
Investigation of the impact of product thickness and strain on cold forging processes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This study investigates the impact of sheet metal thickness and strain generated on a cold forging process. A cold forging die was manufactured based on a numerically modelled product design that considered stress concentration ... -
Drece method for continuous severe plastic deformation of CuZn37 sheets
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This paper presents a continuous severe plastic deformation (SPD) process for sheet metal called Dual Rolls Equal Channel Extrusion (DRECE) is introduced. The DRECE process achieves maximum sheet metal deformation by ... -
The effect of the inlet chamber and diffuser on the reverse aerodynamic performance of an axial flow fan
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Flow reversal in axial fans is usually carried out by changing the direction of rotation of the fan and rotating the stator vanes. The total pressure losses of selected inlet fan chambers were determined using CFD data for ...
