  1. 16. Improving Short-Range Cloud Forecasts in Harmonie-Arome Through Cloud Initialization Using Mesan Cloud Data

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Joakim Pyykkö; [2019]
    Nyckelord :cloud initialization; HARMONIE-AROME; MESAN; satellite product; synoptic weather station;

    Sammanfattning : Previous studies, such as van der Veen (2012) and White et al. (2017), have demonstrated the potential of using measurement-based cloud data to improve Numerical Weather Prediction (NWP) based cloud forecasts. This can be done through cloud initialization; a process of injecting cloud data after the regular data assimilation in an NWP model. LÄS MER

  3. 17. Spacecraft & Hybrid Rocket Motor Flight Model Design for a Deep Space Mission : Scalable Hybrid Rocket Motor for Small Satellite Propulsion

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Pau Molas Roca; [2019]
    Nyckelord :Scalable; Hybrid Rocket Motor; Simulation Algorithm; Small Satellites; Space exploration;

    Sammanfattning : In this thesis, the design and particularities of a unique and revolution- ary scalable propulsion system are presented. A spacecraft mechanical design is included together with a mission definition, aiming to provide a context for a technology demonstration in space of an Hybrid Rocket Motor (HRM) as satellite thruster.

  4. 18. EM emissions test platform implementationfor satellite electric propulsion systems andelectronic subsystems

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Siiri Talvistu; [2019]
    Nyckelord :Electromagnetic compatibility; electromagnetic emissions; compliance; ion thruster;

    Sammanfattning : Modern gridded ion thrusters for CubeSats operate by generating high power and canpose challenging problems with Electromagnetic Interference (EMI). In order to verifycompatibility with neighbouring equipment, strict standards such as the militarystandard MIL-STD-461G, are required to be followed to achieve ElectromagneticCompatibility (EMC).

  5. 19. The effect of snow-cover area change, precipitation and temperature on streamflow in Tärnaån drainage basin, northern Sweden

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Kristin Röja; [2019]
    Nyckelord :;

    Sammanfattning : Snow cover is a fundamental component of the world’s cryosphere and plays an important role in the hydrological cycle. It is significant as a human water resource but can also be an influencing factor in flood and drought generation. LÄS MER

  7. 20. Disaggregating economic inequality from space

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Neija Maegaard Elvekjær; [2019]
    Nyckelord :Visible Infrared Imaging Radiometer Suite VIIRS ; night-time lights; Gross Domestic Product GDP ; economic inequality; regional inequality; spatial inequality; Gini coefficient; spatial scale; Social Sciences; Earth and Environmental Sciences;

    Sammanfattning : Reducing inequality is number 10 of the United Nations sustainable development goals. Inequality in society affect economic growth, development and poverty reduction, and through these indirectly affect environmental degradation, food security and other major problems facing society today.
