  1. 1. Mechanics-based Design Framework for Flexible Pavements

    Författare :Yared H. Dinegdae; Björn Birgisson; David Newcomb; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanics-based; asphalt; fatigue; reliability; traffic; variability; Mekanik-baserade; utmattningssprickor; pålitlighet; lastbilstrafiken; variabilitet; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This paper presents a mechanics-based design framework in load and resistance factor design (LRFD) format for the top-down fatigue cracking performance evaluation of flexible pavements. LÄS MER

  3. 2. Uncertainty Management for Automated Diagnostics of Production Machinery

    Författare :Károly Szipka; Andreas Archenti; Giuliano Bissacco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty Management; Automated Diagnostics; Inertial Measurement Unit; SRA - Produktion; SRA - Production;

    Sammanfattning : Neither production machinery, nor production systems will ever become completely describable or predictable. This results in the continuous need for monitoring and diagnostics of such systems in order to manage related uncertainties. LÄS MER

  4. 3. Reliability Evaluation of Distribution Systems Considering Failure Modes and Network Configuration

    Författare :Sajeesh Babu; Patrik Hilber; Chanan Singh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Power distribution networks are recognized as the constituent part of power systems with the highest concentration of failure events. Even though the faults in distribution networks have a local effect when compared to the generation and transmission sides, major contingency escalation events are being more frequently reported from this section.
