1. 21. Reliability-based Assessment of Concrete Dam Stability

   Författare :Marie Westberg; Avdelningen för Konstruktionsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; stability; concrete dam; structural reliability analysis; probability; uplift; system reliability;

   Sammanfattning : Risk management is increasingly used in dam safety and includes risk analysis, risk evaluation and risk reduction. Structural Reliability Analysis (SRA) is a probabilistic methodology that may be used in the risk assessment process. LÄS MER

3. 22. Supporting complete vehicle reliability forecasts

   Författare :Julia Lindén; Ulf Sellgren; Anders Söderberg; Fredrik Elgh; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability forecast; interactive function; operating conditions; Machine Design; Maskinkonstruktion;

   Sammanfattning : Reliability is one of the properties that customers of heavy trucks value highest.Dependent on all parts and functions of the vehicle, reliability is a complexproperty, which can normally be measured only towards the end of a developmentproject. At earlier development stages, forecasts can give valuable decision supportfor project planning. LÄS MER

4. 23. Cooperative Communications : Link Reliability and Power Efficiency

   Författare :Tafzeel ur Rehman Ahsin; Ben Slimane; Xavier Lagrange; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. LÄS MER

5. 24. Performance and Reliability in Open Router Platforms for Software-Defined Networking

   Författare :Voravit Tanyingyong; Peter Sjödin; Markus Hidell; Jeong Woo Cho; Mats Björkman; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance; reliability; OpenFlow; software-defined networking SDN ; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The unprecedented growth of the Internet has brought about such an enormous impact on our daily life that it is regarded as indispensable in modern era. At the same time, the underlying Internet architecture is still underpinned by principles designed several decades ago. LÄS MER

7. 25. Reliability Assessment and Probabilistic Optimization in Structural Design

   Författare :Rami Mansour; Mårten Olsson; Xioping Du; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability-based design optimization RBDO ; First- and Second-Order Reliability Method FORM and SORM ; Response Surface Single Loop RSSL ; Probability of failure; Reliability Assessment; Probability of fatigue failure; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : Research in the field of reliability based design is mainly focused on two sub-areas: The computation of the probability of failure and its integration in the reliability based design optimization (RBDO) loop. Four papers are presented in this work, representing a contribution to both sub-areas. LÄS MER
