Shock wave configuration in a transonic flow through a mid-section of a last stage turbine blade cascade equipped with a part-span connector
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
This paper deals with the study of a flow field and namely the configuration of shock waves in a blade cascade equipped with a part-span connector called tie-boss. The cascade consists of prismatic blades formed from the ...
Compression behaviour and failure mechanisms of a safety culvert made of hollow high-performance concrete blocks
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
The safety culvert composed of hollow high-performance concrete blocks is designed to reduce the risk of injury in the event of a collision. This work presents a new design with an opening for water flow, tests it, identifies ...
Effect of cross-sections data on calculated static neutronic parameters of PWR MOX/UO2 core transient benchmark case using NODAL3 code
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
This paper describes the effect of cross-section data generated by several codes on calculated neutronic parameters. The Pressurized Water Reactor Mixed Oxide and Uranium Oxide (PWR MOX/UO2) Core Transient Benchmark case ...
A comparative experimental investigation of high-temperature effect on fibre concrete and high strength concrete using UT and CM methods
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
In this paper, a 28-day compressive strength test has been performed on samples including normal fibre concrete and high-strength concrete. The ultrasonic test (UT) as a non-destructive and compression machine (CM) as a ...
3D CFD model for the analysis of the flow field through a horizontal axis wind turbine (HAWT)
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
With the world’s growing demand for energy, renewable energy production has become important in providing alternative sources of energy and in reducing the greenhouse effect. This study investigates the aerodynamics and ...
Mechanical and physical properties of cement mixtures for 3D processing
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
In this paper, information about cementitious composite materials for further 3D processing is discussed and supplemented. Many of the research in this area focuses primarily on cement composites suitable for 3D printing. ...
Construction of angular-dependent potentials from trigonometric Pöschl-Teller systems within the Dunkl formalism
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
We generate solvable cases of the two angular equations resulting from variable separation in the three-dimensional Dunkl-Schrödinger equation expressed in spherical coordinates. It is shown that the Dunkl formalism ...
Stator current signal crossing for fault diagnosis of self-excited induction generators
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
This paper presents a novel method for modelling and diagnosis of electrical and mechanical faults in fixed-Speed Self-Excited Induction Generators (SEIGs) operating in autonomous mode in a small-scale wind energy system. ...
Fake face detection based on a multi discriminator deep CNN architecture (MDD-CNN)
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
Due to the robustness of the deep learning tools used to design these applications, fakes are becoming increasingly common as these applications become more widely available and accessible to the general public. These fakes ...
Geometric approach to solving inverse kinematics of six DOF robot with spherical joints
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
Inverse kinematics is a fundamental concept in robotics that plays a crucial role in a robot’s ability to perform tasks. In this contribution, we propose a novel geometric approach based on vector calculus to solve the ...
