  1. 1. Pre-biotic molecules and dynamics in the ionosphere of Titan : a space weather station perspective

    Författare :Oleg Shebanits; Jan-Erik Docent; Ingo Müller-Wodarg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Saturn; Titan; Ionosphere; Langmuir Probe; Space and Plasma Physics; Rymd- och plasmafysik;

    Sammanfattning : Saturn’s largest moon Titan (2575 km radius) is the second largest in the Solar system. Titan is the only known moon with a fully developed nitrogen-rich atmosphere with ionosphere extending to ~2000 km altitude, hosting complex organic chemistry. LÄS MER

  3. 2. Modelling Weather Dynamics for Weather Derivatives Pricing

    Författare :Emanuel Evarest Sinkwembe; Martin Singull; Xiangfeng Yang; Fredrik Berntsson; Erik Lindström; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This thesis focuses on developing an appropriate stochastic model for temperature dynamics as a means of pricing weather derivative contracts based on temperature. There are various methods for pricing weather derivatives ranging from simple one like historical burn analysis, which does not involve modeling the underlying weather variable to complex ones that require Monte Carlo simulations to achieve explicit weather derivatives contract prices, particularly the daily average temperature (DAT) dynamics models.

  4. 3. Snow deposit melt and atmospheric icing : analysis and modelling by weather station data

    Författare :Eva Sundin; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Snow deposit melt should be included when dealing with urban run off. Every winter structures experience atmospheric icing. The objective was to develop physically sound models based on weather station data for estimating snow melt and atmospheric icing. LÄS MER

  5. 4. Titan’s ionosphere and dust : – as seen by a space weather station

    Författare :Oleg Shebanits; Jan-Erik Wahlund; Wolf Dietrich Geppert; Olle Björneholm; Erik Vigren; Cesar Bertucci; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Titan; Cassini; Ionosphere; Dusty plasma; Ion-ion plasma; Langmuir probe; aerosols; tholins; Space and Plasma Physics; Rymd- och plasmafysik;

    Sammanfattning : Titan, the largest moon of Saturn, is the only known moon with a fully developed nitrogen-rich atmosphere, its ionosphere is detectable as high as 2200 km above its surface and hosts complex organic chemistry. Titan’s atmosphere and ionosphere has striking similarities to current theories of these regions around Earth 3.5 billion years ago. LÄS MER

  7. 5. Efficient Winter Road Maintenance : A Study of Technical and Contractual Issues

    Författare :Adel Abdi; Hans Lind; Björn Birgisson; Lars Silver; KTH; []
