  2. 2. Modelling the transient response of windings, laminated steel coresand electromagnetic power devices by means of lumped circuits With special reference to windings with a coaxial insulation system

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pär Holmberg; Uppsala universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Transient response; frequency response; electromagnetic transient analysis; circuit modeling; eddy currents; skin effect; windings; coils; magnetic cores; cables; electric machines; rotating electric machines; transformers; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

    Abstract : 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. READ MORE

  3. 3. Sources and Diagnostics for Attosecond Science

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

    Abstract : 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. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

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

    Abstract : 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.
