  1. 1. Electronic and Vibrational Coherence in Photosynthetic and Model Systems

    Detta är en avhandling från Chemical Physics, Lund University

    Författare :Mirianas Chachisvilis; Lund University.; Lunds universitet.; [1996]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Ultrafast relaxation; Porphyrins; Delocalization; Anisotropy; Wavepacket; Vibrational Coherence; Excitons; Electronic coherence; Energy transfer; Femtosecond spectroscopy; Photosynthesis;

    Sammanfattning : Ultrafast optical response and excitation energy dynamics in light harvesting pigment-protein complexes and in a few model systems have been studied both experimentally and theoretically. Femtosecond light pulses were employed to excite the system and monitor the subsequent time evolution of the transient absorption kinetics and anisotropy. LÄS MER

  2. 2. Quantum Coherence for Light Harvesting

    Detta är en avhandling från Chemical Physics, Lund University

    Författare :David Palecek; Lund University.; Lunds universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coherent two-dimensional spectroscopy; Quantum coherence; Light harvesting; Photosynthetic reaction center; Energy transfer;

    Sammanfattning : Almost all life on Earth depends on the products of photosynthesis — the biochemical process whereby solar energy is stored as chemical-rich compounds. The energy of captured photons is transferred through a network of pigment-protein complexes towards the reaction center. LÄS MER

  3. 3. On State-Space Models in System Identification

    Detta är en avhandling från Linköping : Linköping University

    Författare :Tomas McKelvey; Linköpings universitet.; Linköpings universitet.; [1994]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis considers identification of multivariable discrete time linear systems by using time-invariant state-space models of finite dimension. A new model structure is introduced that is fully parametrized, i. e. all matrices are filled with parameters. LÄS MER

  4. 4. Identification of State-Space Models from Time and Frequency Data

    Detta är en avhandling från Linköping : Linköping University

    Författare :Tomas McKelvey; Linköpings universitet.; Linköpings universitet.; [1995]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This dissertation considers the identication of linear multivariable systems using finite dimensional time-invariant state-space models.Parametrization of multivariable state-space models is considered. A full parametrization, where all elements in the state-space matrices are parameters, is introduced. LÄS MER

  5. 5. Advanced process monitoring and analysis of machining

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Peter Norman; Luleå tekniska universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : Milling is a processing technology massively applied in the metal manufacturing industry. The continuous demand for higher productivity and product quality asks for better understanding and control of the machining process. LÄS MER
