  1. 16. Bias in prediction : on correction methods

    Författare :Sven Rydberg; Stockholms universitet; []
    Nyckelord :;

    Sammanfattning : .... LÄS MER

  3. 17. Satellite microwave measurements of cloud ice properties

    Författare :Bengt Rydberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sub-mm; cirrus; upper troposphere; Odin; remote sensing; CloudSat; data retrieval;

    Sammanfattning : Upper tropospheric cloud ice and water vapour are two intimately connected components of the atmosphere, that influence the Earth's energy budget. The response of these components to a warming climate is not well understood. LÄS MER

  4. 18. Satellite microwave measurements of ice cloud properties

    Författare :Bengt Rydberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cirrus; radiative transfer; CIWSIR; microphysical properties; inversions; Odin;

    Sammanfattning : Ice clouds play an important role in Earth's radiation balance and climate because they reflect incoming sunlight and trap outgoing infrared radiation. There is still an uncertainty about how ice clouds will respond to the effects of global warming. Many climate models use prognostic cloud mass schemes to represent cloud feedbacks. LÄS MER

  5. 19. Gravitational lensing as a probe of the first stars and galaxies

    Författare :Claes-Erik Rydberg; Erik Zackrisson; Lise Christensen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stars: Population III; first stars; Galaxies: high-redshift; Galaxies: Population III; dark ages; reionization; techniques: photometric; Astronomy; astronomi;

    Sammanfattning : This thesis investigates the potential for detection and identification of primordial stars, galaxies, and supernovae at high redshift.Simulations indicate that the first Population III stars should appear in minihalos of mass M = 105-106 Msol at z ≈ 10-30. LÄS MER

  7. 20. Partially Coherent Laser Radiation - Modeling and Application to Optical Microlithography

    Författare :Christer Rydberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microlithography; coherence; temporal speckle; partial coherence; optical propagation; number of degrees of freedom; dynamic speckle;

    Sammanfattning : This work deals with a type of light that has properties somewhere between blackbody radiation and conventional laser light; such light is referred to as partially coherent. One example is the radiation from the pulsed excimer laser, which is used in the manufacturing of most of the worlds integrated circuits. LÄS MER
