  1. 21. Styrbar systemförvaltning : att organisera systemförvaltningsverksamhet med hjälp av effektiva förvaltningsobjekt

    Författare :Malin Nordström; Göran Goldkuhl; Ulf Melin; Anders G. Nilsson; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Systemförvaltning; Computer networks - Management; Computer science; Datavetenskap;

    Sammanfattning : Många organisationer som anvander IT-system i sin verksamhet bedriver ocksa någon form av systemförvaltningsverksamhet. Någon eller några aktörer har till uppgift att kontinuerligt vidmakthålla och vidareutveckla organisationers verksamhet med hjälp av IT-system. LÄS MER

  3. 22. Model-Driven Process Design : Aligning Value Networks, Enterprise Goals, Services and IT Systems

    Författare :Erik Perjons; Paul Johannesson; Anders G. Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; business process design; e-process design; model-driven methods; enterprise modelling; business modelling; enterprise goals; services; value networks; business-IT alignment; design science; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. LÄS MER

  4. 23. X-ray scattering and spectroscopy of supercooled water and ice

    Författare :Jonas A. Sellberg; Anders Nilsson; Lars G. M. Pettersson; Thomas Loerting; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supercooled water; ice; x-ray scattering; x-ray spectroscopy; free-electron laser; kemisk fysik; Chemical Physics;

    Sammanfattning : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. LÄS MER

  5. 24. Information and Communication Technology Applied for Developing Countries in a Rural Context : Towards a Framework for Analysing Factors Influencing Sustainable Use

    Författare :Susanne Sundén; Gudrun Wicander; John-Sören Pettersson; Anders G. Nilsson; Louise Yngström; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; Informatik; Information Systems; Informatik;

    Sammanfattning : Information and Communication Technology (ICT) has been considered a tool that can be used to achieve development goals in developing countries. In the same time, the majority of people living in developing countries, and especially those in rural areas lack access to ICT. LÄS MER

  7. 25. Simulation of Core-Level Spectra of H-bonded Systems

    Författare :Iurii Zhovtobriukh; Lars G.M. Pettersson; Anders Nilsson; Marcus Lundberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water; x-ray absorption; non-resonant x-ray emission; damped linear response theory; time-dependent density functional theory; semi-classical approximation to Kramers-Heisenberg formula; Reverse Monte-Carlo; kemisk fysik; Chemical Physics;

    Sammanfattning : The thesis consists of three related projects where attempts have been made to simulate X-Ray Absorption (XAS) spectra of water and hexagonal ice, static non-resonant X-ray Emission (XES) spectrum of water and to apply the semi-classical approximation to Kramers-Heisenberg formula (SCKH) formalism to calculate the non-resonant XES spectrum of water and methanol. The first project is devoted to an investigation of the performance of damped response theory in combination with the DFT electronic structure method (CPP-DFT) in XAS spectrum simulations of liquid water.
