  2. 21. Resistive Wall Mode Stability and Control in the Reversed Field Pinch

    Author : Dmitriy Yadikin; Per Brunsell; Mikhail Gryaznevich; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resistive wall modes; RWM; active control; feedback; MHD modes; Reversed-Field pinch; RFP; intelligent shell; mode control; Electrophysics; Elektrofysik;

    Abstract : Control of MHD instabilities using a conducting wall together with external magnetic fields is an important route to improved performance and reliability in fusion devices. Active control of MHD modes is of interest for both the Advanced Tokamak and the Reversed Field Pinch (RFP) configurations. READ MORE

  4. 22. Project management ontology : the organizational learning perspective

    Author : Heli Aramo-Immonen; Kaj U. Koskinen; Jari Palomäki; Finland Tampere Tampere University of Technology; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mega-project; project learning; organizational learning; systems thinking; activity theory; management ontology;

    Abstract : In a recent interview with the Financial Times, the chief executive of Royal Dutch Shell, Mr. Jeroen van der Veer, said he “keeps faith in ‘elephant’ projects” referring to the Russian gas mega-project that Shell had fallen eight months behind schedule with and had cost overruns twice the original estimate. Mr. READ MORE

  5. 23. Magnetic Resonance Parameters of Radicals Studied by Density Functional Theory Methods

    Author : Lyudmyla Telyatnyk; KTH; []
    Keywords : electronic g-tensor; hyperfine coupling constant; nuclear shielding tensor; spin restricted DFT; restricted-unrestricted appoach;

    Abstract : The recent state of art in the magnetic resonance area putsforward the electron paramagnetic resonance, EPR, and nuclearmagnetic resonance, NMR, experiments on prominent positions forinvestigations of molecular and electronic structure. A mostdifficult aspect of such experiments is usually the properinterpretation of data obtained from high-resolution spectra,that, however, at the same time opens a great challenge forpure theoretical methods to interpret the spectral features.

  6. 24. (2,0) Theory and Higher Spin: Twisting, Turning and Spinning Towards Higher Energies

    Author : Hampus Linander; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates an enigmatic six-dimensional quantum theory known as (2,0) theory and a three dimensional conformal theory of higher spin. The former has resisted an explicit construction as a quantum field theory, yet its existence can be inferred from string theory and M-theory where it plays a prominent role. READ MORE

  7. 25. Theory of Random Matrices and Elasticity Applied to Nanowires and Mechanical Vibrations

    Author : Johan Grönqvist; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis presents work in several areas relating to Random Matrix Theory and Elasticity. It contains 4 papers presenting work on different issues. Paper I concerns correlations between eigenvalues in random matrices of real symmetric (GOE) or quaternion real (GSE) form. READ MORE
