  2. 6. Markov Regime Switching in Economic Time Series

    Author : Ulf Erlandsson; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; forecasting; Markov switching; exchange rates; interest rates; business cycle; economic policy; economic systems; economic theory; econometrics; Economics; currency crisis;

    Abstract : This dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. READ MORE

  4. 7. PROTEIN FOLD SWITCHING IN COARSE-GRAINED MODELS

    Author : Christian Holzgräfe; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Holzgräfe; coarse-grained model; protein folding; evolution; fold switching;

    Abstract : Proteins carry out the instructions encoded in genes and are crucial for many important tasks in the living organism. Often the specific three dimensional structure, or fold, of a protein enables it to carry out a given task. READ MORE

  5. 8. Design, analysis and simultion for optical access and wide-area networks

    Author : Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

    Abstract : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. READ MORE

  6. 9. On soft-switching isolated AC/DC converters without auxiliary circuit

    Author : Staffan Norrga; Stefan Östlund; Rik De Doncker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; voltage source converter; cycloconverter; isolated converter; medium frequency transformer; soft switching; modulation; commutation; wind power; electric traction; Elkraftteknik; Electric power engineering; Elkraftteknik;

    Abstract : The thesis is concerned with a class of power electronic converter systems that permit bidirectional AC/DC conversion with galvanic separation of the AC and DC sides by a transformer operating at elevated frequency. The systems consist of a capacitively snubbered voltage source converter and a cycloconverter, separated by the mentioned transformer. READ MORE

  7. 10. A Mode Switching Modelling Philosophy

    Author : Jan-Erik Strömberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The thesis presents a modelling methodology for the systematic derivation of mathematical behaviour mod els of engineering systems , i. e. systems constructed by engineers. The first part presents the theoretical and philosophical foundation underlying a dass of methods generally referred to as physical modelling. READ MORE
