1. 1. Wildfire growth modelling in Sweden - a suitability assessment of available data

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

   Författare :Henrik Hagelin; [2023]
   Nyckelord :Geography; GIS; Geographic Information Science; Physical geography; Prometheus; WiSE-FASS; The 2014 Västmanland wildfire; Wildfire growth modelling; Wildfire suppression support; Wildfire behaviour; MESAN; Earth and Environmental Sciences;

   Sammanfattning : Wildfires are worldwide problems that stress societies by damaging their economies and they cause serious, sometimes fatal, health implications among the populations. In recent years, the rate of wildfire occurrence has increased as the global average temperature has risen. Because of global climate change, this rate is expected to continue rising. LÄS MER

3. 2. Multi-scale Bark Beetle Predictions Using Machine Learning

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

   Författare :Albert Øhrman Wellendorf; [2023]
   Nyckelord :Geography; GIS; Geographically weighted regression; bark beetle; machine learning; Earth and Environmental Sciences;

   Sammanfattning : Bark beetle attacks have led to widespread tree disturbance and deaths in many parts of the world, and thereby also economic and biodiversity losses. Forest-rich Sweden has experienced periodic attacks, latest in 2018. LÄS MER

4. 3. Highway Traffic Forecasting with the Diffusion Model : An Image-Generation Based Approach

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Pengnan Chi; [2023]
   Nyckelord :Diffusion model; Traffic forecasting; Generative model; Image processing; Spatial temporal modelling; Diffusionsmodell; Trafikprognos; Generativ modell; Bildbehandling; Rumsligtemporal modellering;

   Sammanfattning : Forecasting of highway traffic is a common practice for real traffic information system, and is of vital importance to traffic management and control on highways. As a typical time-series forecasting task, we want to propose a deep learning model to map the historical sensory traffic values (e.g., speed, flow) to future traffic forecasts. LÄS MER

5. 4. Digital Model of a Mining Stacker for Material Tracking : Modelling a Mining Stacker with Forward Kinematics for Material Tracking

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Livia Maria Waller; [2023]
   Nyckelord :Mining; Material tracking; Bucket wheel stacker; Gruvteknik; Materialspårning; Skovelhjulsstaplar;

   Sammanfattning : The Fourth Industrial Revolution is reshaping the manufacturing industry with the emergence of interconnectivity, smart automation, and cyber-physical systems. A popular example of cyber-physical systems is the digital twin or digital model, which both create a virtual (cyber) representation of a system. LÄS MER

7. 5. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Benjamin Holmberg; [2022-09-01]
   Nyckelord :Tibetan Plateau; monsoon; westerlies; mesoscale; convection; precipitation; climate modelling; global reanalysis; regional downscaling; spatial resolution; re-initialization; spectral nudging; convective parameterization;

   Sammanfattning : The Tibetan Plateau (TP) is one of the world’s most important water towers. Convective precipitation systems play an important role by providing freshwater for the highly densely populated downstream regions, but they can also cause hazardous floods. LÄS MER
