  1. 1. Top-down Fabrication Technologies for High Quality III-V Nanostructures

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Shagufta Naureen; KTH.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V nanostructures; colloidal lithography; top-down fabrication; dry etching; quantum well; multilayer structures; nanowires; nanopillars; nanodisks; mono-layer etching; surface passivation; photoluminescence; carrier life time; total reflectivity; photonic crystals; nanomesh;

    Abstract : III-V nanostructures have attracted substantial research effort due to their interesting physical properties and their applications in new generation of ultrafast and high efficiency nanoscale electronic and photonic components. The advances in nanofabrication methods including growth/synthesis have opened up new possibilities of realizing one dimensional (1D) nanostructures as building blocks of future nanoscale devices.

  2. 2. Top-Down Designers vs Bottom-Up Users : limitations of Heuristic Evaluations on Games

    University dissertation from Stockholm University

    Author : Björn Strååt; Stockholms universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Design; Heuristic evaluation; video games; expert analysis; user comments; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : Heuristic evaluations are a common way to measure software usability, both during development and to assess existing systems. Generic heuristic tools are aimed at productivity software, but many software domains require domain-specific heuristics. READ MORE

  3. 3. Anthropogenic impact on predator guilds and ecosystem processes Apex predator extinctions, land use and climate change

    University dissertation from Stockholm : Department of Zoology, Stockholm University

    Author : Marianne Pasanen Mortensen; Stockholms universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mesopredators; apex predators; top-down; bottom-up; interspecific killing; red fox; Eurasian lynx; grey wolf; wolverine; productivity; winter severity; cropland; zoologisk ekologi; Animal Ecology;

    Abstract : Humans affect ecosystems by changing species compositions, landscape and climate. This thesis aims to increase our understanding of anthropogenic effects on mesopredator abundance due to changes in apex predator status, landscape and climate. READ MORE

  4. 4. Flipping the pyramid lessons from converting top-down management of bleak-roe fishing

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Carl Rova; Luleå tekniska universitet.; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Statsvetenskap;

    Abstract : The fishing of vendace (Coregonus albula), in the northern part of the Gulf of Bothnia, is a good illustration of the presumption that institutional arrangements which are too inflexible to cope with changing ecological conditions are unlikely to prosper. The aim of this thesis is to contribute to the development of a better understanding of governance in a relatively small and clearly defined, but complex common-pool resource system. READ MORE

  5. 5. Modelling drivers of energy demand in the European Union building sector

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Eoin Ó Broin; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EU; Elasticities; Heating; Policy; Bottom-up; Top-down; Efficiency; Residential;

    Abstract : In the context of ongoing initiatives within the European Union (EU) to tackle global warming and to secure future energy supplies, the building sector is often cited as offering strong potential for energy savings. The primary aims of this thesis are to analyse the historical data related to EU building and to generate scenarios that highlight the technical and non-technical parameters that affect the energy demands (and thereby the potentials for savings) of the building sector.
