  1. 6. A Critical Review of the Observational Method

    Författare :Johan Spross; Stefan Larsson; Fredrik Johansson; Joakim Jeppsson; Lars Rosén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock mechanics; observational method; Eurocode 7; reliability analysis; dam safety; tunnelling; system reliability; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Building a sustainable structure in soil or rock that satisfies all predefined technical requirements implies choosing a rational and effective construction method. An important aspect is how the performance of the structure is verified. LÄS MER

  3. 7. Setting occupational exposure limits : Practices and outcomes of toxicological risk assessment

    Författare :Linda Schenk; Christina Rudén; Alan Boobis; Michael Gilek; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Assessment Factor; DNEL; Euroepan Union; Occupational Exposure Limit; REACH; Risk Assessment; Regulatory Toxicology; SCOEL; Uncertainty Factor; Toxicology; Toxikologi;

    Sammanfattning : Occupational Exposure Limits (OELs) are used as an important regulatory instrument to protect workers’ health from adverse effects of chemical exposures. The main objective of this thesis is to study risk assessment practices in the setting of OEL in order to produce knowledge that will help improve the consistency and transparency of OELs. LÄS MER

  4. 8. Assessment of Concrete Structures Including Corrosion and Cracks

    Författare :Mattias Blomfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reinforced concrete; corrosion; nonlinear FE analysis; reinforcement bond; assessment; cracks;

    Sammanfattning : Reinforced concrete (RC) structures constitute a major proportion of the built environment and society relies continuously on their service. Many of these structures were built in the era following the Second World War and are thus approaching the end of their intended service life. LÄS MER

  5. 9. Holistic approach in engineering design - controlling risks from accidental hazards in bridge design

    Författare :Ivar Björnsson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design; codes; accidental; extreme; bridges; holistic; approach; robustness; risk; reliability; uncertainty;

    Sammanfattning : Engineering design, in concise terms, is what engineers do using what they know. It is the underlying decision making activity that determines what is to be built and how it should be built. An ever present requirement in engineering design is that the structure should be safe.

  7. 10. On the Precision Grip in Manual Transport

    Författare :Nasser Hosseini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The aim of the present study was to investigate the grip and load force relations in the precision grip (between thumb and index finger) in static and dynamic situations, and to develop automatic procedures for the analysis of position and force data from tests involving the precision grip. The goal of the work was to create physiologically based methods for identification and quantitative determination of disturbances in the nervous control of hand motor function. LÄS MER
