  1. 1. Simulating Earthquake Rupture and Near-Fault Fracture Response

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Billy Fälth; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Sammanfattning : Sweden is presently a low seismicity area where most earthquakes are small and pose no serious threat to constructions. For the long-term perspectives of safety assessments of geological repositories for spent nuclear fuel, however, the effects of large earthquakes have to be considered. LÄS MER

  2. 2. Three Phase Controlled Fault Interruption Using High Voltage SF6 Circuit Breakers

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Richard Thomas; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; controlled switching; high voltage; hypothesis testing; circuit breakers; fault interruption; least mean squares regression; power system protection;

    Sammanfattning : A method is presented for implementing controlled fault interruption,using high voltage, SF6 circuit breakers on three phase high voltage powernetworks. The main goal of the method is to synchronize the opening or tripcommands to each phase of a circuit breaker with respect to target currentzero times so that each phase will interrupt with a preselected arcingtime.

  3. 3. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Stavros Tzilis; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

    Sammanfattning : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.

  4. 4. Performance Studies of Fault-Tolerant Middleware

    Detta är en avhandling från Institutionen för datavetenskap

    Författare :Diana Szentiványi; Linköpings universitet.; Linköpings universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Programming; aspect-oriented programming; software engineering; distribution transparently; Common Object Request Broker Architecture COBRA ; algorithm; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : Today’s software engineering and application development trend is to take advantage of reusable software. Much effort is directed towards easing the task of developing complex, distributed, network based applications with reusable components. To ease the task of the distributed systems’ developers, one can use middleware, i.e. LÄS MER

  5. 5. Dynamic threshold generators for robust fault detection

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Michael Bask; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Detection of faults, such as clogged valves, broken bearings or biased sensors, has been brought more and more into focus during the last few decades. There are two main reasons why faults are important to detect at an early stage. LÄS MER
