  1. 6. InP High Electron Mobility Transistors for Cryogenic Low-Noise and Low-Power Amplifiers

    Författare :Eunjung Cha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indium channel content; electrical stability.; dc power dissipation; noise temperature; scaling; low-noise amplifier LNA ; InP high-electron mobility transistor InP HEMT ; cryogenic;

    Sammanfattning : The InAlAs/InGaAs/InP high-electron mobility transistor (InP HEMT) is the preferred low-noise device in cryogenic low-noise amplifiers (LNAs) operating at 5-15 K. Such LNAs are utilized in microwave and millimeter-wave detection in radio astronomy. LÄS MER

  3. 7. Evaluation of Students' Attitudes Towards Vocational Education in Jordan

  5. 9. Reduction of Aerodynamic Forcing inTransonic Turbomachinery : Numerical Studies on Forcing Reduction Techniques

    Författare :Florian Fruth; Torsten Fransson; Damian Vogt; Ronald Mailach; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forced Response; Aerodynamic Forcing; Efficiency; Blade Count Ratio; Clocking;

    Sammanfattning : Due to more and more aggressive designs in turbomachinery, assuring the structural integrity of its components has become challenging. Also influenced by this trend is blade design, where lighter and slimmer blades, in combination with higher loading, lead to an increased risk of failure, e.g. in the form of blade vibration.
