  1. 1. Effects of Prolonged Electricity Supply Disruptions on Critical Entities

    University essay from Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : André Hansson; [2023]
    Keywords : vital societal function; VSF; critical entity; CE; vital societal entity; VSE; critical infrastructure; CI; critical flow; prolonged outage; electricity supply disruption; preparedness; total defence; civil defence; civil preparedness; crisis preparedness; grey zone; critical entities resilience; CER; hybrid warfare; energy security; societal resilience; cascading effect; dependencies; interdependencies; long-term disruption; power outage; power disruption; consequences; outage; samhällsviktig verksamhet; kritisk infrastruktur; totalförsvar; beredskap; Technology and Engineering;

    Abstract : This study investigates Swedish critical entities (CEs) ability to maintain function during up to three months of electricity supply disruptions. It also examines possible improvement measures, and how contextual cases (grey zone, heightened state of alert, war) influence CEs’ ability to maintain function during electricity supply disruptions.

  3. 2. Analysis of a high step-up gain DC-DC converter for fuel cell and battery application

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Kaj Törngren Sato; [2023]
    Keywords : Fuel cell; High step-up DC-DC converter; Boost converter; Coupled inductors; Coupling factor; CCM; DCM; Duty cycle;

    Abstract : In sustainable energy systems those using fuel cells, high step-up gain converters are widely used to increase the output voltage to levels that can be used by other converters, such as inverters for grid connection or powering other AC loads. In order to obtain a higher voltage gain, in comparison to a traditional boost converter, often different topologies techniques are involved. READ MORE

  4. 3. Spatial and temporal variability in grassland structure associated with different densities of the white rhinoceros (Ceratotherium simum) in a South African savanna

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Emilia Malmström; [2019]
    Keywords : white rhinoceros; african savanna; keystone species; herbivory; cascading effects; poaching;

    Abstract : The direct and indirect relationships between species in different trophic levels are referred to as trophic dynamics and are important in maintaining the function of ecosystems. Megaherbivores may have effects both directly and indirectly on other species since their impact may be disproportionately large relative to their population size. READ MORE

  5. 4. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : David Kymmell; [2019]
    Keywords : landscape of fear; forest fire effects; herbivore prey; camera trapping;

    Abstract : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

  6. 5. Room vs greenDAO for Android : A comparative analysis of performance of Room and greenDAO

    University essay from Mittuniversitetet/Institutionen för data- och systemvetenskap

    Author : Longho Bernard Che; [2019]
    Keywords : Android; persistence; database; Room; greenDAO; Lista i annat språk:Android; databas; persistence; Room; greenDAO;

    Abstract : Android developers often store relational data using databases. There are a couple of database frameworks from which an Android developer can choose. Application performance is often considered when developers choose libraries and frameworks for their applications. READ MORE
