  1. 21. Photoluminescence Studies of Single Quantum Dots

    Författare :Nikolay Panev; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stranski-Krastanow; photoluminescence; laser spectroscopy; antibunching; random telegraph noise; blinking; Physics; Fysik; Fysicumarkivet A:2004:Panev; solid immersion lens; quantum dots; low-dimensional structures;

    Sammanfattning : This thesis presents photoluminescence (PL) spectroscopy studies of single III-V semiconductor quantum dots (QDs). The electronic properties of the QDs, as well as, the dynamics of the processes taking part inside and in the surroundings of the QDs have been studied by single quantum dot photoluminescence spectroscopy, time resolved spectroscopy, and correlation spectroscopy.

  3. 22. On the Bone Tissue Response to Surface Chemistry Modifications of Titanium Implants

    Författare :Byung-Soo Kang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osseointegrated titanium implants; Magnesium and Calcium Incorporated Bioactive Titanium Oxide; Metal Plasma Immersion Ion Implantation and Deposition; Micro Arc Oxidation; Clinical Implants; In Vivo Bone Response;

    Sammanfattning : Background: Surface properties of titanium implants play an important role in osseointegration. From 1990, a lot of engineering techniques have been applied to dental implant productions for improving their clinical performance by changing surface properties. LÄS MER

  4. 23. Mind the Gap : Exploring the social capability of non-player characters

    Författare :Henrik Warpefelt; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data- och systemvetenskap; Computer and Systems Sciences;

    Sammanfattning : Among the most important factors governing enjoyment of computer games is immersion, or the feeling the player has of being in the game world. This feeling allows the player to be transported into the world of the game, where they can experience grand adventures and riveting tales. LÄS MER

  5. 24. On some positive effects of swirling flow for the continuous cast mould billets

    Författare :Shavkat Kholmatov; Pär Jönsson; Simon Lille; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; swirling flow; round mould; divergent angle; aspect ratio; temperature distribution; velocity fluctuations; continuous casting of steel; mathematical modeling; CFD; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : Continuous caster moulds are the last and most important stage in the steelmaking process, where inclusions can either be generated or removed. With increasing casting speed using conventional immersion nozzles critical problems, such as unstable bulk mould flow have been noticed. LÄS MER

  7. 25. Cardiovascular and hematological responses to voluntary apnea in humans

    Författare :Robert de Bruijn; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organism biology; Organismbiologi;

    Sammanfattning : This thesis deals with cardiovascular and hematological responses to voluntary apnea in humans, with a special focus on O2 usage and storage. Humans, and many other air‐breathing animals, respond to apnea (breath holding) with a collection of interacting cardiovascular reflexes, which are collectively called the diving response. LÄS MER
