  1. 1. I-girder Composite Bridges with Lateral Bracing : Improved load distribution

    Författare :Victor Vestman; Peter Collin; Robert Hällmark; Hans Petursson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assessment; bridge; composite bridge; steel-concrete composite; I-girder; case study; horizontal trusses; lateral bracing; rehabilitation; strengthening; torsional stiffness; upgrading; Byggkonstruktion; Structural Engineering;

    Sammanfattning : This thesis deals with the subject of lateral bracing between the bottom flanges of I-girder composite bridges. The focus is on the impact of adding lateral bracing on existing bridges, as well as on new bridges. LÄS MER

  3. 2. Damage Tolerance of Impacted Composite Sandwich Structures

    Författare :Moeen ud din Saeed Rajput; Malin Åkermo; Stefan Hallström; Magnus Burman; Christian Berggreen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite sandwich; cellular; polymer; material characterization; modulus; non-crimp fabric; low velocity impact; vibration; uncertainty analysis; drop-weight impact; fractography; barely visible impact damage; X-ray microtomography; compression-after-impact; bending-after-impact; high speed image processing; damage resistance; damage tolerance; Aerospace Engineering; Flyg- och rymdteknik;

    Sammanfattning : This thesis deals with damage tolerance of impacted sandwich structures for load bearing applications. Composite sandwich structures find wide application as lightweight solutions in aerospace components, since weight reduction and less fuel emissions are primary concerns for aircraft manufactures.

  4. 3. On Possibilities of Using Smart Meters for Compulsory Load Shedding Supported by Load Forecasting

    Författare :Yasir Arafat; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power quality; Remote switching; Electrical distribution system; Smart meter; Compulsory load shedding; Load forecasting;

    Sammanfattning : The smart meter rollout is progressing in several parts of the world with early adoption in some parts, e.g., Europe. Remote ON/OFF control switch of the smart meter allows distribution system operators to switch the smart meter of any customer remotely. LÄS MER

  5. 4. Dynamic Power System Load -Estimation of Parameters from Operational Data

    Författare :Ines Romero; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; large disturbances; Load modeling; normal operation; voltage stability; dynamic load models; modeling and identification; normalization in reactive load models; Elektronik och elektroteknik; Electronics and Electrical technology; Automatiska system; robotteknik; reglerteknik; Electrical engineering; Elektroteknik;

    Sammanfattning : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. LÄS MER

  7. 5. Cognitive load in dialogue interpreting : Experience and directionality

    Författare :Aleksandra Adler; Elisabet Tiselius; Birgitta Englund Dimitrova; Christopher D. Mellinger; Agnieszka Chmiel; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; dialogue interpreting; cognitive load; interpreting experience; directionality; cognitive translation and interpreting studies; disfluency; eye-tracking; mixed-methods; översättningsvetenskap; Translation Studies;

    Sammanfattning : This dissertation investigates the effect of experience and language direction on cognitive load in dialogue interpreting. The general objective of the study is to contribute to a better understanding of cognitive processes involved in dialogue interpreting. LÄS MER
