  1. 1. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

    Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport;

    Sammanfattning : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. LÄS MER

  3. 2. Multiple Time Scales and Longitudinal Measurements in Event History Analysis

    Författare :Danardono; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Cox regression; multiple events; proportiona hazards; random effects; survival analysis; time-dependent covariates; time origin; Statistik; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.

  4. 3. Time for Hyperons : Development of Software Tools for Reconstructing Hyperons at PANDA and HADES

    Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Laura Fabbietti; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hyperon; Track reconstruction; 4D tracking; Free-streaming data; Kinematic fitting; PANDA; HADES; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

    Sammanfattning : The PANDA experiment at FAIR offers unique possibilities for performing hyperon physics. The detector will enable the reconstruction of both hyperon and antihyperon, which will be created together in proton-antiproton collisions. This enables investigations of the strong interaction in the non-perturbative regime. LÄS MER

  5. 4. Att utforska sitt ursprung : Identitetsformande under adolescensen hos utlandsfödda adopterade: betydelsen av biologiskt och etniskt ursprung

    Författare :Malin Irhammar; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Development psychology; adolescence; Identity formation; adoptees born abroad; ethnical origin; biological origin; Utvecklingspsykologi;

    Sammanfattning : Within the Eriksonian identity tradition, exploration of different life domains is crucial to identity formation. This is a process supposed to start during adolescence and develop in a social context. LÄS MER

  7. 5. Gene : on the origin, function and development of sedentary Iron Age settlement in northern Sweden

    Författare :Per H. Ramqvist; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; sedentary; settlement; colonization; internal development; origin; development; three-aisled long-houses; house construction; room division; inter-regional structure; iron forging; bronze casting; Järnåldern;

    Sammanfattning : This thesis deals with questions concerning the sedentary settlement in central Norrland: its origins, function and development. This type of settlement appears at the start of our calendar. The material comprises an almost fully excavated farmstead from the Early Iron Age (1-600 A.D. LÄS MER
