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

    Author : Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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.

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

    Author : Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Laura Fabbietti; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Per H. Ramqvist; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. A class of origin : The school class as a social context and health disparities in a life-course perspective

    Author : Ylva Almquist; Viveca Östberg; Michael Gähler; Bjørn Holstein; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children; School class; Social structure; Social networks; Health inequalities; Longitudinal; Sociology; Sociologi; Sociology; sociologi;

    Abstract : The aim of the present thesis is to examine various aspects of the school-class structure and their links to health in a life-course perspective. The empirical studies are based on two longitudinal data materials of cohorts born in the 1950s, followed up until middle age. READ MORE
