  1. 1. Arbitrary motion Synthetic Aperture Radar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Filip Alberius; Erik Rolander; [2023]
    Nyckelord :RADAR; SAR; Synthetic Aperture Radar; Pulsed Coherent Radar; PCR; VR; Virtual Reality; IMU; Inertial Measurment Unit; VAA; Virtual Antenna Array; Obstacle detection; Signal Processing; Matched Filter Method.; Technology and Engineering;

    Sammanfattning : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. LÄS MER

  3. 2. Välkommen till Rapport, men först, det här är Dagens Eko : En kvantitativ innehållsanalys om vilka nyhetsgenrer som får plats i SVT:s Rapport kontra SR:s Ekot.

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för medier och journalistik (MJ)

    Författare :Simon Karlsson; [2022]
    Nyckelord :Public service; Rapport; Ekot; SVT; SR; broadcast; programme; news; radio; television; segment; Public service; Rapport; Ekot; SVT; SR; sändning; program; nyhet; radio; tv; segment;

    Sammanfattning : The aim of the study is to see what topics the news programmes Rapport on Swedish Television and Ekot on Swedish Radio report on in their broadcasts and to see how different news genres take their place in the programmes. Rapport and Ekot are two of Sweden's biggest news programmes and I want to analyse what is similar in their broadcasts and what is different. LÄS MER

  4. 3. Delivering sustainable energy transition : A techno-economic analysis on households, businesses and communities of the Keweenaw Peninsula

    Master-uppsats, KTH/Energiteknik

    Författare :Francesca Longobardi; Filippo Padovani; [2020]
    Nyckelord :;

    Sammanfattning : Energy security understood as the practice by which risks associated with interruptions to the energy supply are low, represents one of the main objectives of energy policies in many countries. In this context, Keweenaw County or Michigan's northernmost County is placed as locked in an unreliable, unsustainable and particularly wasteful energy system. LÄS MER

  5. 4. Drag based forecast for CME arrival

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Simon Jaklovsky; [2020]
    Nyckelord :CME; ICME; Halo coronal mass ejections; DBM; DBEM; solar wind; interplanetary medium; shock; space weather forecast; geoeffectivity; solar-terrestrial interaction;

    Sammanfattning :           Coronal Mass Ejections (CMEs) are considered to be one of the most energetic events in the heliosphere. Capable of inducing geomagnetic storms on Earth that can cause damage to electronics, a pillar which the modern society we live in leans heavily upon. LÄS MER

  7. 5. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Ludvig Sjöberg; [2019]
    Nyckelord :Weather Research and Forecasting Model; Large Eddy Simulation; Microscale Meteorology;

    Sammanfattning : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.
