    • Application of the Source-Jerk method using a neutron generator in a subcritical reactor 

      Author: Rataj, Jan; Mátl, Jakub; Suk, Pavel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      This paper describes the application of the Source-Jerk method using a neutron generator in the VR-1 reactor. The experiments were carried out on a shutdown reactor with subcriticality greater than -10 βeff. A D-D neutron ...

    • Fake face detection based on a multi discriminator deep CNN architecture (MDD-CNN) 

      Author: Bencheriet, Chemesse Ennehar; Abdelmoumène, Hiba; Sebbagh, Abdennour; Yahiyaoui, Abdennour; Taba, Zahra
      (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 

      Author: Hadidi, Nacer; Bouaziz, Mohamed; Mahfoudi, Chawki; Zaharuddin, Mohamed
      (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 ...

    • Improving QoS in mobile multimedia streaming with SCTP-PQ 

      Author: Hüseynli, Alisettar; Şimşek, Mehmet; Akcayol, M. Ali
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      The Stream Control Transmission Protocol (SCTP) is often the preferred transport layer protocol in streaming applications. This protocol combines the best aspects of Transmission Control Protocol (TCP) and User Datagram ...

    • PAPR reduction in CP-OFDM (5G) using hybrid technique 

      Author: Yusof, Azlan; Idris, Azlina; Abdullah, Ezmin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      The Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) is a 5G multicarrier waveform that offers great data speeds and improvements in spectrum utilisation. The primary CP-OFDM’s weakness is its excessive ...

    • Stator current signal crossing for fault diagnosis of self-excited induction generators 

      Author: Belynda, Fares; Abdelli, Radia; Bouzida, Ahcene
      (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. ...

    • The effect of ambient temperature on the delay time of perimeter protection 

      Author: Ďurica, Jakub; Sovjak, Radoslav; Boroš, Martin; Kuffa, Radoslav
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)
      Perimeter security defines the private space from the public space and also serves as the first barrier between the intruder and the protected interest. Delay time is one of the input parameters used in a quantitative ...
