  1. 16. Development of a method for studying cascading effects between critical infrastructures

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

    Author : Björn Arvidsson; [2015]
    Keywords : Cascading effects; critical infrastructure protection; incident investigation; conditions; counterfactual reasoning; empirical method; flooding; Technology and Engineering;

    Abstract : Most current methods for studying cascading effects rely on written sources to extract information. This thesis presents an empirical method for studying cascading effects, when little written information of the event is available. The method presented has been influenced by incident investigation methods. READ MORE

  2. 17. Ecotoxicological effects on a food-web exposed to pharmaceuticals : Uptake and effects of oxazepam, fexofenadine and a mixture of both in algae, zooplankton and sticklebacks.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Sundelin; [2015]
    Keywords : Bioconcentration; Bioaccumulation; Behaviour; Pharmaceutical mixtures.;

    Abstract : Complex mixtures of biologically active pharmaceutical residues continuously enter aquatic environments via wastewater, where it can affect species through preserved human drug targets or cause unexpected effects in non-target species. Benzodiazepines and antihistamines are two highly consumed groups of pharmaceuticals that have been shown to bioconcentrate in aquatic organisms and induce behavioural alterations affecting individual fitness.

  3. 18. Hydropower in Sweden : An investigation of the implications of adding detail to the modelling of hydropower in OSeMOSYS

    University essay from KTH/Energisystemanalys

    Author : Cecilia Flood; [2015]
    Keywords : OSeMOSYS; hydropower; hydropower storage; energy modelling optimisation;

    Abstract : The purpose of this thesis is to generate a deeper understanding of the representation of hydropower in long-term models. This is done by mapping and modelling (cascading) hydropower in Sweden with the Open Source energy MOdelling SYStem (OSeMOSYS). READ MORE

  4. 19. The suitability of using Landsat TM-5 Images for estimating chromophoric dissolved organic matter in subarctic Lakes

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Jakobsson; [2014]
    Keywords : CDOM; dissolved organic carbon; colored dissolved organic matter; Chromophoric; landsat thematic mapper 5; subarctic lakes; Stordalen; empirical algorithm.; Abisko; DOC; remote sensing; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : Recent trends of permafrost thawing in the subarctic are expected to cause increased release of dissolved organic carbon (DOC) to inland waters, which might have cascading effects on downstream aquatic ecosystems and release of CO2 to the atmosphere. This study therefore aimed at evaluating the applicability of an empirical band ratio algorithm for estimating chromophoric dissolved organic matter (CDOM; a proxy for DOC) from the easily accessible satellite images Landsat TM-5, to counter the inaccessibility of the region in general.

  5. 20. Investigation of Large Signal Effects onCascaded Travelling Wave ElectroAbsorption Modulator (CTWEAM)Performance and Optimization

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Hamidul A. B. M. Islam; [2012]
    Keywords : ;

    Abstract : In this thesis work large signal model of cascaded travelling wave electroabsorption modulator (CTWEAM) has been studied. The effect of input modulating voltage, input optical power, biasing voltage, and circuit parameters on bandwidth, extinction ratio and overshooting of this modular carefully investigated. READ MORE
