  2. 11. Dynamic Power System Load -Estimation of Parameters from Operational Data

    Author : Ines Romero; Industriell elektroteknik och automation; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 12. Cognitive load in dialogue interpreting : Experience and directionality

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

    Abstract : 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. READ MORE

  5. 13. Combining cognitive and physical work tasks: Short-term effects on fatigue, stress, performance and recovery

    Author : Susanna Mixter; Svend Erik Mathiassen; David Hallman; Petra Lindfors; Paul Jarle Mork; Högskolan i Gävle; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical; repetitive; cognitive; mental; load; variation; job rotation; restoration; allostatic load; fysisk; repetitiv; kognitiv; mental; belastning; variation; arbetsrotation; återhämtning; allostatisk belastning; Health-Promoting Work; Hälsofrämjande arbete;

    Abstract : Background: Although combinations of physical and cognitive work tasks occurs in working life (both concurrent and alternating), no one has summarized the research regarding such combinations. Very few studies have investigated the effects of alternating physical and cognitive tasks, which have been suggested as an alternative to classic job rotation. READ MORE

  6. 14. Dynamic Load Models for Power Systems - Estimation of Time-Varying Parameters During Normal Operation

    Author : Ines Romero; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage stability; Load modeling; modeling and identification; dynamic load models; normalization in reactive load models;

    Abstract : Economic and environmental concerns will slow down the expansion of the transmission system in many countries. The addition of new transmission lines will be few and far between. The de-regulation of the power supply will introduce new power flow patterns on the bulk transmission systems. READ MORE

  7. 15. The morselized and impacted bone graft. Animal experiments on proteins, impaction and load

    Author : Magnus Tägil; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; orthopaedics; Surgery; load; growth factors; graft healing; remodeling; allograft; Impaction grafting; morselized graft; Kirurgi; ortopedi; traumatologi; Immunology; serology; transplantation; Immunologi; serologi;

    Abstract : This thesis focuses on the healing and remodeling of the morselized and impacted bone allograft, commonly used in revision of loosened hip prostheses with osteolysis. The influence on remodeling by the impaction procedure per se was analyzed, as well as the effects of endogenous bone graft proteins, and an exogenously applied growth factor (OP-1). READ MORE
