  1. 6. Attrition in Studies of Cognitive Aging

    Författare :Maria Josefsson; Xavier de Luna; Lars Nyberg; Anders Lundquist; Mattias Villani; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attrition; missing data; age-related cognitive change; non- ignorable dropout; monotone missing pattern; mixture models; pattern- mixture models; imputation; Statistics; statistik;

    Sammanfattning : Longitudinal studies of cognition are preferred to cross-sectional stud- ies, since they offer a direct assessment of age-related cognitive change (within-person change). Statistical methods for analyzing age-related change are widely available. LÄS MER

  3. 7. Automated Creation of Safety Cases for Highly Configurable Systems

    Författare :Damir Nešić; Mattias Nyberg; Ewen Denney; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

    Sammanfattning : Regardless of the domain, the size and complexity of software-intensive systems is constantly increasing. At the same time, to satisfy the needs of different customers, systems are more frequently being engineered as configurable, where individual customers can select the configuration that suits them best.

  4. 8. Probabilistic Fault Diagnosis with Automotive Applications

    Författare :Anna Pernestål; Mattias Nyberg; Gautam Biswas; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The aim of this thesis is to contribute to improved diagnosis of automotive vehicles. The work is driven by case studies, where problems and challenges are identified. To solve these problems, theoretically sound and general methods are developed. The methods are then applied to the real world systems. LÄS MER

  5. 9. Residual Generation Methods for Fault Diagnosis with Automotive Applications

    Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

    Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER

  7. 10. A Decision Support System for Integration Test Selection

    Författare :Sahar Tahvili; Markus Bohlin; Daniel Sundmark; Stig Larsson; Wasif Afzal; Mattias Nyberg; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Software testing generally suffers from time and budget limitations. Indiscriminately executing all available test cases leads to sub-optimal exploitation of testing resources. Selecting too few test cases for execution on the other hand might leave a large number of faults undiscovered. LÄS MER
