  1. 21. Waves and rays in open billiards

    Författare :Torbjörn Blomquist; John B. Delos; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Semiconductor systems where the deBroglie wavelength of the electron is comparable to the size of the system are called mesoscopic. Such systems are readily produced in laboratories, and have been studied extensively. These systems offer possibilities to study the borderline between quantum and classical physics, chaos and more.

  3. 22. Targeting and driving somatosensory neurons

    Författare :Fabio Freitag; Malin C. Lagerström; Andrew Todd; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pain; Itch; GRPR interneurons; dorsal horn; trigeminal nucleus caudalis; Barrel field;

    Sammanfattning : Pain and itch are two distinct sensations, but the fundamental question of how our nervous system distinguishes the processing and encoding of their related information is still far to be clearly delineated. At the spinal cord level, evidences have pointed out specific groups of neurons expressing the gastrin releasing peptide (Grp) and its receptor (Grpr) as responsible for carrying specifically itch-related information.

  4. 23. InP HEMT Technology and Applications

    Författare :Anders Mellberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Indium phosphide InP ; cryogenic LNA; high electron mobility transistor HEMT ; metal-insulator-metal capacitor; MODFET; thin film resistor; semiconductor device fabrication; MMIC;

    Sammanfattning : Indium phosphide high electron mobility transistors (InGaAs/InAlAs/InP HEMTs) exhibit the highest cut-off frequencies and the lowest microwave noise figures of all transistor technologies. Both InP HEMT technology and associated circuit demonstrators are therefore interesting to explore further. LÄS MER

  5. 24. Efficient Simulation and Optimal Control for Vehicle Propulsion

    Författare :Anders Fröberg; Lars Nielsen; Karl-Henrik Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : Efficient drive cycle simulation of longitudinal vehicle propulsion models is an important aid for design and analysis of power trains. Tools on the market today mainly use two different methods for such simulations, forward dynamic or quasi-static inverse simulation. LÄS MER

  7. 25. Identification of Time Varying Systems and Application of System Identification to Signal Processing

    Författare :Alf Isaksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Time varying systems; Signal processing;

    Sammanfattning : Part IA new approach to identification of time varying systems is presented, and evaluated using computer simulations. The new approach is built upon the similarities between recursive least squares identification and Kalman filtering. LÄS MER
