  2. 1. Averaging level control in the presence of frequent inlet flow upsets

    Author : Peter Rosander; Alf J. Isaksson; Johan Löfberg; Morten Hovd; Linköpings universitet; []
    Keywords : Averaging level control; PI control; Surge tanks; Optimal control; Robust MPC; Process control;

    Abstract : Buffer tanks are widely used within the process industry to prevent flow variations from being directly propagated throughout a plant. The capacity of the tank is used to smoothly transfer inlet flow upsets to the outlet. Ideally, the tank thus works as a low pass filter where the available tank capacity limits the achievable flow smoothing. READ MORE

  4. 2. High-resolution measurement of the ¹⁶O(γ,pn) reaction

    Author : Lennart Isaksson; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pn ; E_gamma = 67-76 MeV; resolved states; cross-sections; Nuclear physics; Kärnfysik; Fysicumarkivet A:1996:Isaksson; 16O gamma; Photonuclear reaction;

    Abstract : The 16O(gamma,pn) reaction has been measured with a resolution high enough to resolve individual low-lying states in the residual 14N nucleus. The relative population of the states provides detailed information about the quantum numbers of the proton-neutron pairs on which photons are absorbed. READ MORE

  5. 3. On the quantitative analysis of electronic energy transfer/migration in proteins studied by fluorescence spectroscopy

    Author : Mikael Isaksson; Lennart Johansson; Bo Albinsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysical Chemistry; Biophysical chemistry; Biofysikalisk kemi;

    Abstract : Two recently developed theories of electronic energy transfer/migration were for the first time applied to real protein systems for extracting molecular distances. The partial donor-donor energy migration (PDDEM) is an extension to the previously developed donor-donor energy migration (DDEM, F Bergström et al PNAS 96, 1999, 12477) which allows using chemically identical but photophysically different fluorophores in energy migration experiments.
