  3. 2. 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.

    Sammanfattning : Attaining Whiteness is the first book-length sociological study of how ideas about race resonate in post-Soviet Russia. The book charts how tropes of self, hybridity, and maturity constitute important symbolic vehicles for applying the idea of race to the drawing of differences. LÄS MER

  5. 4. Essays on Unit-Root Testing and on Discrete-Response Modelling of Firm Mergers

    Författare :Nikolay Angelov; Per Johansson; Steinar Strøm; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; unit root; structural break; LR test; stationary alternative; matching; firm mergers; discrete choice; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : Essay 1 investigates the time-series properties of the price of iron ore. The focus is on unit-root testing in the presence of a structural break. Unit-root tests with or without structural breaks are applied to historical prices of five different qualities of Swedish and Brazilian iron ore. Tests with exogenous or endogenous breaks are analyzed. LÄS MER

  7. 5. The Integrated Distributed Hydrological Model, ECOFLOW- a Tool for Catchment Management

    Författare :Nikolay Sokrut; Roger Thunvik; Tuomo Karvonen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrogeology; Multiple-scale hydrological modelling; Bayesian algorithm; Parameter estimation; Groundwater management; Statistical analysis; Hydrogeologi; Hydrology; Hydrologi;

    Sammanfattning : In order to find effective measures that meet the requirements for proper groundwater quality and quantity management, there is a need to develop a Decision Support System (DSS) and a suitable modelling tool. Central components of a DSS for groundwater management are thought to be models for surface- and groundwater flow and solute transport. LÄS MER
