  1. 1. Topics in Modeling, Control, and Implementation in Automotive Systems

    Författare :Magnus Gäfvert; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

    Sammanfattning : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. LÄS MER

  3. 2. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

    Författare :Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []

    Sammanfattning : This thesis concerns two related data analysis pipelines, using topological and geometrical methods respectively, to extract relevant information. The first pipeline, referred to as the topological data analysis (TDA) pipeline, constructs a filtered simplicial complex on a given data set in order to describe its shape. LÄS MER
