  - Przegląd Telekomunikacyjny + Wiadomości Telekomunikacyjne - Year 2017

  SDN is the approach in telecommunication networks that separates control plane from data forwarding plane by specifying a single network entity as a controller that defines rules (called flows) of traffic forwarding for the switches connected to it. The time that is required for installation of these rules might be a hindrance for the overall performance of SDN network. In the paper, a model for testing and evaluating the influence...

  - Roads and Bridges - Drogi i Mosty - Year 2011

  Przedstawiono opis badań pali i kolumn wkręcanych typu SDP i SDC na terenowym poletku doświadczalnym, wykonanych w ramach projektu badawczego MNiSW. Badania statyczne pali i kolumn wykonano z pomiarem rozdziału siły w trzonach i w powiązaniu z badaniami CPT podłoża gruntowego. Określono wartości oporów jednostkowych gruntów niespoistych wzdłuż pobocznicy i pod podstawą pali wkręcanych oraz przedstawiono je w relacji do oporów gruntu...

  - JOURNAL OF COMPOSITE MATERIALS - Year 2022

  Due to their high density-specific stiffnesses and strength, fibre reinforced plastic (FRP) composites are particularly interesting for mobility and transport applications. Warp-knitted non-crimp fabrics (NCF) are one possible way to produce such FRP composites. They are advantageous because of their low production costs and the ability to tailor the properties of the textile to the reinforcement and drape requirements of the application....

  Technologia Wieloprotokołowej Komutacji Etykietowej (MPLS – MultiProtocol Label Switching) dostarcza odpowiednie mechanizmy wspierające proces zachowania jakości usług, jednak wymaga nadrzędnego elementu sterującego. Takim elementem może być kontroler zrealizowany w koncepcji Sieci Definiowanych Programowo (SDN – Software Defined Networking), wprowadzający abstrakcję, rozdzielającą płaszczyznę przekazywania od płaszczyzny sterowania....

• Performance Evaluation of a 650V E-HEMT GaN Power Switch

  Publication

  • P. Czyż

  - Year 2015

  GaN power switches have better characteristics compared to the state-of-the-art Si power transistors. These devices offer high operating temperature and current densities, fast switching and low on-resistance. However, currently only a few producers offer technology of high voltage GaN transistors. Immaturity of this technology is the reason why experimental evaluation of GaN parameters must be performed to properly exploit their...
