  1. 1. Identification and Simulation Methods for Nonlinear Mechanical Systems Subjected to Stochastic Excitation

    Författare :Andreas Josefsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear structural dynamics; system identification; simulation; non-deterministic excitation; zero-memory nonlinear systems; wave power engineering;

    Sammanfattning : With an ongoing desire to improve product performance, in combination with the continuously growing complexity of engineering structures, there is a need for well-tested and reliable engineering tools that can aid the decision making and facilitate an efficient and effective product development. The technical assessment of the dynamic characteristics of mechanical systems often relies on linear analysis techniques which are well developed and generally accepted. LÄS MER

  3. 2. Prognostic markers in prostate cancer : studies of a watchful waiting cohort with long follow up

    Författare :Andreas Josefsson; Anders Bergh; Pernilla Wikström; Pär Stattin; Anders Bjartell; Umeå universitet; []

    Sammanfattning : Background: Prostate Cancer (PC) is a common and highly variable disease. Using current diagnostic methods, the prostate specific antigen (PSA) blood test and histological grading of prostate tissue needle biopsies, it is often difficult to evaluate whether the patient has a PC that requires active treatment or not.

  4. 3. Synthesis and spectroscopic characterization of emerging synthetic cannabinoids and cathinones

    Författare :Andreas Carlsson; Johan Dahlén; Martin Josefsson; Peter Konradsson; Simon Dunne; Mikael Hedeland; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The application of different analytical techniques is fundamental in forensic drug analysis. In the wake of the occurrence of large numbers of new psychoactive substances possessing similar chemical structures as already known ones, focus has been placed on applied criteria for their univocal identification.

  5. 4. Quantum Electro- and Acoustodynamics in Waveguides

    Författare :Andreas Josefsson Ask; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The study of light-matter interaction in superconducting quantum circuits has seen remarkable progress over the last $20$ years. By engineering artificial atoms, novel quantum phenomena have been demonstrated, and old ideas have come into a new light. LÄS MER

  7. 5. En framgångsrik främling : Filadelfiaförsamlingen i Stockholm - självbild i historieskrivning och verksamhet 1910-1980

    Författare :Andreas K.G. Thörn; Christina Carlsson Wetterberg; Ulrik Josefsson; Håkan Forsell; Lars-Åke Skalin; Daniel Lindmark; Örebro universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Historical narrative; group identity; Swedish Pentecostal Movement; church history; Free Churches; Historia; History;

    Sammanfattning : The aim of the thesis is to examine how a group’s self-image is created, sustained and if necessary changed during the revolutionary 20th century. The study takes its point of  eparture in the idea that a self-image is essential for an organisation’s cohesion and collective identity. LÄS MER
