  1. 1. Software Process Improvement Framework

    Författare :Natalja Nikitina; Mira Kajko-Mattsson; Pekka Abrahamsson; KTH; []
    Nyckelord :software process; process improvement; SPI; software method adoption; organizational change; change management; organizational aspects; social aspects; managerial aspects; SPI success factors; SPI checklist; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Many software development organizations today are keen on improving their software development processes in order to develop software products faster, cheaper or better. For that reason, Software Process Improvement (SPI) has received significant attention from the research community over the last few decades. LÄS MER

  3. 2. Software Process Assessment & Improvement in Industrial Requirements Engineering

    Författare :Tony Gorschek; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Process Assessment; Process Improvement; Requirements Engineering; Abstraction; Requirements; SPI; RE;

    Sammanfattning : Requirements Engineering (RE) is a crucial part of any product management and product development activity, and as such deficiencies in the RE process may have severe consequences. There are reports from industry that point towards inadequate requirements being one of the leading sources for project failure. LÄS MER

  4. 3. Simulations of Biomolecular Fragmentation and Diffraction with Ultrafast X-ray Lasers

    Författare :Christofer Östlin; Carl Caleman; Nicusor Timneanu; Helmut Grubmüller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray free-electron laser; X-ray imaging; Single particle imaging; Computer simulation; Radiation damage; Molecular dynamics; Diffraction theory; Coulomb explosion; Sample heterogeneity; Diffractive noise; XFEL; SPI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Studies of biomolecules have recently seen substantial developments. New X-ray lasers allow for high-resolution imaging of protein crystals too small for conventional X-ray crystallography. Even structures of single particles have been determined at lower resolutions with these new sources. LÄS MER

  5. 4. Polymer and Protein Physics : Simulations of Interactions and Dynamics

    Författare :Anna Sinelnikova; Johan Nilsson; Carl Caleman; Erik Lindahl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymers; proteins; Monte Carlo; molecular dynamics; phase diagram; renormalisation group; SPI; polymer effective model; coarse-graining; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Proteins can, without any exaggeration, be called the "building blocks of life". Their physical properties depend not only on the chemical structure but also on their geometric shape. In this thesis, I investigate protein geometry using several different methods.We start with a coarse-graining model to study the general behavior of polymers. LÄS MER

  7. 5. Late Holocene spatiotemporal hydroclimatic variability over Fennoscandia inferred from tree-rings

    Författare :Kristina Seftigen; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tree-rings; Fennoscandia; hydroclimate; SPEI; SPI; ring-width; maximum latewood density; stable isotopes; field reconstruction; point-by-point regression;

    Sammanfattning : There is a broad scientific consensus that the global climate is changing, and that human activity is a significant factor contributing to the change. The response of the hydrological cycle to the warming is far reaching, including increases in the intensification and frequency of extreme hydroclimatological events. LÄS MER
