  1. 1. 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

  2. 2. 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).

  3. 3. Prototype of a dual-band radio unit

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Josef Lundberg; [2018]
    Nyckelord :;

    Sammanfattning : Surveillance and control have come a long way in the last years. Every new mobile phone, most cars, and smartwatches have a global positioning system tracking device built into it. This is just one of the technologies used in order to track and follow. Today it is hard to go anywhere without there being some sort of way of finding you. LÄS MER

  4. 4. City Margins and Exclusionary Space in Contemporary Egypt : An Urban Ethnography of a Syrian Refugee Community in a Remote Low-Income Cairo Neighborhood

    Master-uppsats, Stockholms universitet/Institutionen för Asien-, Mellanöstern- och Turkietstudier

    Författare :Samir Shalabi; [2017]
    Nyckelord :Egypt; Syria; Cairo; 6th of Uktūbar City; inequality; refugees; refuge; space; spatial; urban; city; neighborhood; justice; marginality; exclusion; locality; uneven development; ethnography;

    Sammanfattning : Drawing mainly on Lefebvre’s, Soja’s and Smith’s theorizations of space in order to understand the spatial dynamics of social inequality, this study investigates how a low-income Syrian refugee community negotiates its precarious location in a neighborhood on the periphery of one of Cairo’s desert ‘New Towns’. It also examines the way in which urban spatiality shapes the everyday lived reality of this particular community of Syrians. LÄS MER

  5. 5. Design, Fabrication and Modelling of Three Axis Floating Satellite Simulator

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Junaidh Shaik Fareedh; [2017]
    Nyckelord :;

    Sammanfattning : The Floating Satellite (FloatSat) system project which has been developed at the ‘Department of Aerospace Information Technology - University of Würzburg’ is used to test, develop and implement various attitude control algorithms and strategies for small satellites [1]. The FloatSat project is designed to operate on a Frictionless air bearing surface that works with compressed air flowing distributed on a hemisphere. LÄS MER
