  1. 11. Comparison of operational limit estimations for FRP laminates – effects of material modelling and stochastic behaviour

    Författare :Luis Felipe Sanchez Heres; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety.; FRP; reliability; probability;

    Sammanfattning : Transport companies need vehicles with higher efficiency to remain competitive and comply with environmental regulations. Lightweight construction is one way to increase the efficiency of a vehicle. In some vehicles, lightweight construction can reduce the fuel consumption, increase the cargo capacity and reduce the environmental footprint. LÄS MER

  3. 12. Program Analysis for Performance and Reliability

    Författare :Jacob Lidman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; static dynamic program analysis; abstract interpretation; performance; reliability;

    Sammanfattning : The increased demand for computing power has lead designers to put an ever increasing number of cores on processor dies. This advance has been made possible through miniaturization and effectivization of the underlying semi-conductor technology. As a by-product, however, the resulting computer systems are more vulnerable to interference. LÄS MER

    Sammanfattning : Wave energy, with five times the energy density of wind and ten times the power density of solar, offers a compelling carbon-free electricity solution. Despite its advantages, ongoing debates surround the reliability and economic feasibility of wave energy converters (WECs). LÄS MER

  5. 14. Projective methods and longitudinal developmental research : considerations of data's nature and reliability

    Författare :Harald Janson; Bertil Mårdberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Longitudinal studies; projective methods; reliability; temporal stability; interrater agreement; epistemology; measurement; psykologi; Psychology;

    Sammanfattning : A projective method is viewed in the present work as a psychological test, by which is understood a standardized task that is set before a person, the solution of which is used for making inferences about psychological quantities. The present research was designed to shed light on several aspects of the usefulness of projective methods in longitudinal research, particularly with regard to reliability and to the distinction between measurement and theory-free empirical-comparison data.
