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

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Henrik Hagelin; [2023]
   Keywords : 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;

   Abstract : 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. READ MORE

3. 2. Low Power Current Sensing Node Powered by Harvested Stray Electric Field Energy

   University essay from Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

   Author : Björn Holby; Carl-Fredrik Tengberg; [2015]
   Keywords : Energy Harvesting; Low Power; Sensor; Wireless Communication;

   Abstract : In this thesis, the possibility of harvesting energy from a multicore power cableconnected to a power outlet is presented and evaluated. By surrounding a powercable with a conductive material connected to ground, it is shown that the dif-ference in potential between the power cable and the conductive material causesa capacitance which can charge a capacitor that in combination with an energymanagement circuit can be used to wirelessly transmit data with an interval de-pending on factors like the length of the surrounding material and the type ofcable it is placed around.

4. 3. Assessing the Potential of Embedding Vegetation Dynamics into a Fire Behaviour Model : LPJ-GUESS-FARSITE

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Efren Lopez Blanco; [2014]
   Keywords : mediterranean ecosystem; LPJ-GUESS-FARSITE; FARSITE; fire modelling; fire behaviour prediction; dynamic fuel model; geography; fire recurrence; fuel loading; LPJ-GUESS-SPITFIRE; fuel moisture; physical geography; GEM; Earth and Environmental Sciences;

   Abstract : Disturbances such as wildfires are key players involved in the shape, structure and function of the ecosystems. Fire is rarely included in Dynamic global vegetation models due to their difficulty in implementing its processes and impacts associated. READ MORE

5. 4. Past and present Scots pine (Pinus sylvestris L.) regenaration along site type gradients in Bialowieza Forest, Poland

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Lina Behrens; [2011]
   Keywords : Pinus sylvestris regeneration; oak-lime-hornbeam forest Tilio-Carpinetum; regeneration pulses; forest and fire history; traditional forest utilization;

   Abstract : Since 1921 the Białowieża National Park (BNP)/Poland strictly protects one of the bestpreserved ancient lowland forests of the European temperate zone, with many stands close tonatural character. Within the reserve, old Pinus sylvestris trees grow on fertile soils in a mixeddeciduous forest (oak-lime-hornbeam forest Tilio-Carpinetum) with a very rich and densefield layer. READ MORE

6. 5. Skador orsakade av törskatesvamp på ungskog av tall Pinus sylvestris samt förekomst av kovall i hyggesbrända respektive mekaniskt markberedda bestånd

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Emma Tillberg ; [2010]
   Keywords : Törskate; Cronartium flaccidum; peridermium pini; resin-top; tall; pinus sylvestris; melampyrum; kovall; cronartium rust; brand; hyggesbränning;

   Abstract : Törskatesvamp förekommer i två former, en värdväxlande (Cronartium flaccidum) och en icke värdväxlande (Peridermium pini). Genetiska analyser har visat att ingen övergripande genetisk differentiering finns mellan de två formerna och att de därför tillhör samma art. READ MORE
