    Sammanfattning : Electromagnetic transients impinging on electromagnetic power devices - such as electric machines, transformers and reactors - can stress the design severely. Thus the magnitudes of the transients are often decisive for the design of the devices. Further, the operation of a device can be transient in itself. LÄS MER

  3. 3. Sources and Diagnostics for Attosecond Science

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Miguel Miranda; Lunds universitet.; Lund University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pulse Compression; High-order Harmonic Generation; Ultrafast; Ultrashort; Attosecond; Femtosecond; Pulse Characterization; Fysicumarkivet A:2012:Miranda;

    Sammanfattning : Popular Abstract in English What is a photographic camera flash good for? The easy answer is “to illuminate”. There is more to it though: the duration of a camera flash is usually much shorter than the shutter speed of the camera. This allows us to take sharp pictures of fast objects with an inexpensive camera. LÄS MER

  4. 4. Thermal Conductivity of Materials under Conditions of Planetary Interiors

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Zuzana Konôpková; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; high pressures-high temperatures; thermal conductivity; diamond anvil cell; laser-heating; planetary cores; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap;

    Sammanfattning : The presented thesis focuses on study of transport and thermoelastic properties of materials under conditions of planetary interiors by means of high-pressure experimental tools and finite element modeling, and their role in the dynamics and states of cores of terrestrial planets.Experiments in laser-heated diamond anvil cell (LHDAC) in combination with numerical simulations of heat transfer in DAC are shown to yield information on thermal conductivity of a pressurized sample.
