  1. 1. Exploring Perceptions of Route Environments in Relation to Walking

    Författare :Dan Andersson; Peter Schantz; Lina Wahlgren; Eva Andersson; Maria Johansson; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology;

    Sammanfattning : Background: Every walk takes place in a route environment, which can play an important role in deterring or facilitating walking. The focus of this thesis is on the perceptions of environmental variables, and how they relate to appraisals of route environments as hindering – stimulating for walking and unsafe – safe for reasons of traffic, in two metropolitan environments.

  3. 2. Segmented HPGe detectors for post-irradiation examination of nuclear fuel : Design and demonstration in gamma emission tomography

    Författare :Vikram Rathore; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Andrew Boston; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmented HPGe detector; Nuclear fuel; Post-irradiation examination; Nuclear fuel diagnostics; Gamma emission tomography; Gamma spectroscopy; Non-destructive fuel testing; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : Gamma emission tomography (GET) is a proven non-invasive technique for post-irradiation examination of nuclear fuel. In the past, collimated HPGe detectors were used for GET measurements due to their good energy resolution. LÄS MER

  4. 3. Gamma radiation techniques for non-destructive post-irradiation examination of nuclear fuel : Predicting performance and optimizing instrument design

    Författare :Lorenzo Senis; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Fabiola Cappia; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collimated gamma spectroscopy; Gamma emission tomography; Gamma transmission micro-densitometry; Pareto optimization; Post-irradiation examination; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : Collimated gamma-based techniques are widely used to study nuclear fuel, especially for non-destructive post-irradiation examination (PIE). Examples of such techniques include gamma emission tomography (GET) and gamma transmission densitometry (GTD). LÄS MER

  5. 4. Peter Weiss filmer : från de korta små lekfulla kopparslagen till kommersiell långfilmsdebut: filmer - filmidéer - utkast

    Författare :Jan Christer Bengtsson; Astrid Söderbergh Widding; Lars Gustaf Andersson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Filmhistoria; Peter Weiss; 1950-talet; lång- och kortfilm; experiment- och dokumentärfilm; filmförsök; Film; Filmvetenskap; filmvetenskap; Cinema Studies;

    Sammanfattning : This doctoral thesis deals with Peter Weiss’ (1916-1982) films and some of his never finished attempts. The focus is in general on Weiss’ film work activities in the 1950’s, when film held the very central place in his works of art. LÄS MER

  7. 5. Adaptive Forgetting through Multiple Models and Adaptive Control of Car Dynamics

    Författare :Peter Andersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive forgetting; Multiple models; Adaptive control; Car dynamics;

    Sammanfattning : A new recursive identif ication method, Adaptive Forgetting through Multiple Models - AFMM, is presented and evaluated using computer simulations. AFMM is specif ically suited for identification of systems with jumping or rapidly changing parameters. LÄS MER
