  2. 2. Tracking Theory for Preventive Safety Systems

    Författare :Lars Danielsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle tracking; sensor data fusion; automotive; active safety systems; sensor models; warning integration; motion models; fusion strategies; human machine interface; preventive safety systems;

    Sammanfattning : Preventive safety systems rely on accurate information from a sensing system regarding the current traffic situation to make decision whether to inform, warn or intervene to avoid an impeding collision or to mitigate its consequences. This thesis mainly considers tracking algorithms to enhance these systems through making the best use of the information supplied by on-vehicle sensors, such as radar and vision sensors. LÄS MER

  3. 3. Validity considerations in the study of language learning aptitude

    Författare :Lars Bokander; Kristina Danielsson; Jan H. Hulstijn; Linnéuniversitetet; []
    Nyckelord :HUMANIORA; HUMANITIES; language aptitude; language testing; individual differences; Swedish vocabulary; test validation; Lingvistik; Linguistics;

    Sammanfattning : Language learning aptitude is a hypothesized psychological construct that has been used to explain differences in how fast and how well people can acquire a second language (L2). It is generally assumed that language learning aptitude is a multidimensional phenomenon, meaning that it consists of sub-constructs that are not necessarily interrelated. LÄS MER
