  1. 26. Non-Uniform Sampling in Statistical Signal Processing

    Författare :Frida Eng; Fredrik Gustafsson; Paulo Ferreira; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; signal processing; sampling; stochastic analysis; frequency transform; Automatic control; Reglerteknik;

    Sammanfattning : Non-uniform sampling comes natural in many applications, due to for example imperfect sensors, mismatched clocks or event-triggered phenomena. Examples can be found in automotive industry and data communication as well as medicine and astronomy. LÄS MER

  3. 27. Ship Behaviour and Ship Bridge Allision Analysis

    Författare :Axel Hörteborn; SSPA Sweden AB; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship domain; ship simulations; AIS data; failure statistics; risk modelling;

    Sammanfattning : The demand for maritime transport has increased with the growing demand for worldwide trade. This has led to a major increase in maritime traffic and ship sizes over the last decades, which raises the probability of accidents. LÄS MER

  4. 28. System identification in alternative shift operators with applications and some other topics

    Författare :Britta Fischer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : This thesis mainly concentrates on two issues of system identification, namely identification for controller design and identification with orthonormal basis functions. In identification for controller design one seeks to obtain sufficient knowledge about the plant to design a high-performance controller. LÄS MER

  5. 29. Identification and investigations of leucine-rich repeats and immunoglobulin-like domains protein 2 (LRIG2)

    Författare :Camilla Holmlund; Håkan Hedman; Roger Henriksson; Monica Nistér; Umeå universitet; []
    Nyckelord :LRIG; PDGF; oligodendroglioma; MEDICINE; MEDICIN; onkologi; Oncology;

    Sammanfattning : Receptor tyrosine kinases (RTKs) constitute a family of proteins controlling cell growth and proliferation and whose activities are tightly controlled in normal cells. LRIG1 is a negative regulator of RTK signaling and is a proposed tumor suppressor. The aim of this thesis was to identify and study possible paralogs of LRIG1. LÄS MER

  7. 30. Dynamic response reconstruction using passive components

    Författare :Anders Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; substructuring; controllability; experimental methods; model calibration; passive control; response reconstruction; model updating; drive signal identification; Time Waveform Replication;

    Sammanfattning : In many testing applications within the field of structural dynamics, such as noise and vibration harshness, rattle and squeak, or durability testing in the automotive and truck industries, large hydraulic or electromagnetic actuators are used to excite the tested structure. Such actuators are mounted in the laboratory in a fixed configuration referred to here as a test rig. LÄS MER
