  3. 2. Simulation of Relaxation Processes in Fluorescence, EPR and NMR Spectroscopy

    Författare :Pär Håkansson; Per-Olof Westlund; Yehudi K. Levine; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; EPR; NMR; Energy migration; bicontinuous cubic phase; Stochastic Liouville Equation; Brownian Dynamics; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Relaxation models are developed using numerical solutions of the Stochastic Liouville Equation of motion. Simplified descriptions such as the stochastic master equation is described in the context of fluorescence depolarisation experiments. Redfield theory is used in order to describe NMR relaxation in bicontinuous phases. LÄS MER

  4. 3. Challenged Networking : An Experimental Study of new Protocols and Architectures

    Författare :Erik Nordström; Per Gunningberg; Brian Levine; Uppsala universitet; []
    Nyckelord :Challenged networking; Network Architecture; Wireless Ad hoc Networks; Delay Tolerant Networks; Opportunistic Networks; Testbeds.;

    Sammanfattning : With the growth of Internet, the underlying protocols are increasingly challenged by new technologies and applications. The original Internet protocols were, however, not designed for wireless communication, mobility, long disconnection times, and varying bandwidths. LÄS MER

  7. 5. A new approach to the analyses of fluorescence depolarisation experiments in the presence of electronic energy transport

    Författare :Oleg Opanasyuk; Lennart B-Å Johansson; Per-Olof Westlund; Yehudi Levine; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; electronic energy transfer; donor-donor energy migration; extended Förster theory; fluorescence depolarisation; two-photon excitation; computer simulations; genetic algorithms; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : A new and general procedure is described for a detailed analysis of time-resolved fluorescence depolarisation data in the presence of electronic energy migration. An isotropic ensemble of bifluorophoric molecules (D1-R-D2) has been studied to demonstrate its utility. LÄS MER
