  1. 1. Computer Experiments Designed to Explore and Approximate Complex Deterministic Models

    University dissertation from Linköping : Linköpings universitet

    Author : Davood Shahsavani; Linköpings universitet.; Linköpings universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES Statistics; computer and systems science; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap;

    Abstract : Computer experiments are widely used to investigate how technical, economic, and ecological systems respond to changes in inputs or driving forces. This thesis is focused on design of computer experiments that can help us better understand the output from complex computer code models. READ MORE

    Abstract : There is a rising proportion of aging population worldwide. The high vulnerability of older adults to morbidity and mortality introduces an enormous health and economic burden to themselves and the society. The established leading cause of death among older adults is due to chronic and vascular diseases. READ MORE

  5. 5. Defining and applying surrogate safety measures and behavioural indicators through site-based observations

    University dissertation from Department of Technology and Society, Lund University

    Author : Tim de Ceunynck; Lunds universitet.; Lund University.; [2017-09-29]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surrogate safety measures; behavioural indicators; traffic safety; site-based observations; traffic conflicts; traffic conflict techniques; road user interactions;

    Abstract : This dissertation looks into surrogate safety measures and behavioural indicators that are collected through site-based observations. Surrogate safety measures are defined as measurements that are used to describe the relationship between two road users in a traffic event for the purpose of quantifying the crash probability and/or the potential crash severity in a meaningful way.
