  1. 1. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Alexandros Bampis; [2023]
    Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER

    Kandidat-uppsats, Lunds universitet/Kemisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Fredrik Parnefjord Gustafsson; Jens Uhlig; Wilfred Fullagar; Amal El Nahhas; [2016]
    Nyckelord :pulse energy; pointing; TES; transmission-edge-sensor; EXAFS; spectrum; spectroscopy; absorption; emission; time-resolved; Brunel mechanism; vacuum heating; water-jet; CCD; andor; LPXS; x-ray; plasma; laser; fluctuations; stability; pixel detector; beam profile sensor; resonant absorption; beam position; Physics and Astronomy;

    Sammanfattning : The use of laser based plasma x-ray sources (LPXS) has quickly expanded during the past decades due to rapid development of ultrafast laser systems. These sources are used in many research applications such as emission, absorption and particularly time-resolved spectroscopy. LÄS MER

  4. 3. Minimizing CO2 emission by following ZEB strategies

    Master-uppsats, Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Författare :Elaheh Jalilzadehazhari; [2014]
    Nyckelord :;

    Sammanfattning : AbstractBuildings play an important role in formulating sustainable development, which can help todecrease environmental impacts, such as energy resource depletion, environmental deteriorationand climate change due to the use of fossil base fuels. The zero energy/emission concept isgaining interest as a renewable energy resource. LÄS MER

  5. 4. Optimization of a Predictive Drive Strategy for a Plug-In Hybrid Vehicle : Optimierung der vorausschauenden Antriebssteuerung bei einem Plug-In Hybrid

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Bastian Gindroz; [2014]
    Nyckelord :;

    Sammanfattning : As the world’s natural resources are depleting while the environment constraints on society become om- nipresent, new technological alternatives for transports are sought. Over the past years, the regulations in terms of pollutants stimulated the industries’ innovation in almost all regions of the world, using directives such as the European emission standards have managed to limit the carbon dioxide emissions up to 82% between Euro 1 and Euro 4.

  7. 5. Partially Premixed Combustion (PPC) for low loadconditions in marine engines using computationaland experimental techniques

    Master-uppsats, KTH/Mekanik

    Författare :Kendra Shrestha; [2013]
    Nyckelord :PPC; CFD; Split Injection; Ignition delay; EGR;

    Sammanfattning : Diesel Engine has been the most powerful and relevant source of power in the automobile industryfor decades due to their excellent performance, efficiency and power. On the contrary, there arenumerous environmental issues of the diesel engines hampering the environment. LÄS MER
