  3. 12. Observed and simulated changes in extreme precipitation and cold surges in China: 1961–2005

    Författare :Tinghai Ou; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate extremes; Precipitation; Cold surge; Siberian High; CMIP5; reanalysis; atmospheric circulation;

    Sammanfattning : In the present work, precipitation and temperature related climate extremes are examined, with a focus on Mainland China. The objectives of this study are a) to identify targeted climate extremes and their changes during the last decades, and b) to examine the ability of current global climate models to reproduce identified patterns of change.

  4. 13. Modeling and control of actuators and co-surge in turbocharged engines

    Författare :Andreas Thomasson; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The torque response of the engine is important for the driving experience of a vehicle. In spark ignited engines, torque is proportional to the air flow into the cylinders. Controlling torque therefore implies controlling air flow. LÄS MER

  5. 14. Auroral Electric Fields From Satellite Observations and Numerical Modelling

    Författare :Tomas Karlsson; KTH; []
    Nyckelord :Satellite measurements; electric fields; ionosphere; magnetosphere; diverging electric fields; downward current region; black aurora; westward travelling surge; auroral bulge; subauroral ion drifts SAID ; subauroral electric fields SAEF ; mid-latit; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is about electrodynamics of thehigh-latitude/auroral region of near-Earth space. The work ismainly based on electric field measurements made by the doubleprobe instrument on the Freja satellite at altitudes ofapproximately 800-1700 km, together with measurements fromother instruments on the same satellite, and ground-basedinstrumentation.

  7. 15. The Effects of Lightning on Low Voltage Power Networks

    Författare :Raul Montaño; Vernon Cooray; Marcos Rubinstein; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Lightning induced effects; Lightning Electromagnetic fields; Electromagnetic Compatibility EMC ; Surge Protective Devices SPDs ; Low voltage power networks; Elektroteknik; elektronik och fotonik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : The present society is highly dependant on complex electronics systems, which have a low damage threshold level. Therefore, there is a high risk of partial or total loss of the system’s electronics when they are exposed to a thunderstorm environment. LÄS MER
