  1. 1. Design of a 2-D Lattice Flower Constellation for Earth observation applying the twin satellite concept

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Julia Martín-Fuertes Brañas; [2023]
    Keywords : 2D Lattice Flower Constellation design; number of satellites; number of planes; revisit time; coverage; optimized constellation; target list; twin satellite concept; FreeFlyer; 2D Lattice Flower Constellation design; antal satelliter; antal plan; återbesökstid; täckning; optimerad konstellation; mållista; tvilling-satellit-koncept; FreeFlyer;

    Abstract : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. READ MORE

  3. 2. Near-Real Time Forest Fire Monitoring System From an UAV

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : August Näsman; Daniel Nedlich; [2023]
    Keywords : ;

    Abstract : The purpose of this thesis is to implement a payload system on a drone to help fire towers in near-realtime survey forests for wildfires. The payload system should be able to communicate with a groundstation through a mobile network and the survey should be tagged with relevant metadata. READ MORE

  4. 3. Mot ett mer hållbart lantbruk : En kartläggning av hur livsmedelsaktörer arbetar med miljömässig hållbarhet på gårdsnivå.

    Abstract : Förhöjda havsnivåer, extremväder, översvämningar och skogsbränder är några av de konsekvenser som hotar vår planet på grund av klimatförändringarna. Denna oroande utveckling har lett till en ökad uppmärksamhet kring hållbar utveckling, inte bara i Sverige utan även globalt. READ MORE

  5. 4. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

    University essay from Lunds universitet/Matematisk statistik

    Author : Marcus Gehrmann; [2023]
    Keywords : Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

    Abstract : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

  6. 5. To clear-cut or not to clear-cut; Cost-benefit analyses of post-fire management approaches in the Ljusdal fire-complex

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Bella Blomqvist; [2023]
    Keywords : Clear-cut forestry; Continous cover forestry; Nature reserve; Cost-benefit analysis; Wildfires; Sweden; Ljusdal; Post-fire management; Earth and Environmental Sciences;

    Abstract : Wildfires causes natural disturbances to ecosystems which can have potentially damaging results for ecosystem services and economic income from timber production. The post-fire management approach can be essential for the environmental work regarding the recovery of ecosystems and maintaining ecosystem services. READ MORE
