  1. 1. Studies on hybrid superconducting junctions

    Författare :Cecilia Holmqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Critical Current; Single-Electron Box; Attractive Correlations; Josephson Junction; Negative Charging Energy; Quasiclassical Superconductivity; Josephson Current;

    Sammanfattning : In the field of nanoelectronics, one seeks to combine quantum mechanical effects with macroscopic entities such as currents in order to find new ways of storing and manipulating information. One possibility to accomplish this is to use the quantum correlations found in superconductors. LÄS MER

  3. 2. Improving strategic decisions for real estate investors : Perspectives on allocation and management

    Författare :Sigrid Katzler; Svante Mandell; Inga-Lill Söderberg; Elias Oikarinen; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public real estate; private real estate; MPT; time-varying correlation; liquidity; mixed-asset portfolio; real estate portfolio; diversification; outsourcing; Fastigheter och byggande; Real Estate and Construction Management;

    Sammanfattning : Real estate is an attractive asset class in the mixed-asset portfolio due to favorable risk return characteristics and low correlations with other asset classes like stock and bonds. Unlike financial assets, real estate is a physical asset where large lot sizes/indivisibility, heterogeneity, low liquidity and high transaction costs make applying financial models like modern portfolio theory (MPT) challenging.

  4. 3. Electronic properties of double quantum wires in a magnetic field

    Författare :Sviatoslav Korepov; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : The electronic properties of double quantum wires (DQW) in presence of a per-pendicular magnetic field are investigated theoretically. Analytical solution of theproblem of electronic spectrum is obtained in the framework of the two-subbandmodel for the DQW. LÄS MER

  5. 4. Hidden Markov Models: Identification, Inverse Filtering and Applications

    Författare :Robert Mattila; Bo Wahlberg; Cristian R. Rojas; John Lygeros; Jan H. van Schuppen; Tobias Rydén; Ayca Özcelikkale; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden Markov models; HMM; inverse filtering; identification; estimation; method of moments; counter-adversarial autonomous systems; adversarial signal processing; belief estimation; abdominal aortic aneurysm; medical; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : A hidden Markov model (HMM) comprises a state with Markovian dynamics that is hidden in the sense that it can only be observed via a noisy sensor. This thesis considers three themes in relation to HMMs, namely, identification, inverse filtering and applications. LÄS MER

  7. 5. Modelling and Simulation of Thermal Radiation in Biomass Combustion

    Författare :Thomas Nilsson; Förbränningsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat load; gas turbine; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; porous media; fixed bed; biomass; wood; FG-DVC; combustion; DOM; P1-approximation; Mie theory; RDG-PFA; EWBM; thermal radiation; soot;

    Sammanfattning : This thesis presents numerical investigations and simulations of fixed bed combustion of wood, models for predicting thermal radiative properties of particles and gases related to the combustion of wood, and a review of heat load calculations in gas turbines. All subjects have a common factor in thermal radiation. LÄS MER
