    Sammanfattning : Firms use management accounting, controls and performance measurement to ensure that employee activities are aligned with organizational goals and strategies. Performance is measured at different levels: industry, firm, project and activity. LÄS MER

  4. 8. Predicting IT Governance Performance : A Method for Model-Based Decision Making

    Författare :Mårten Simonsson; Pontus Johnson; Wim Van Grembergen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IT governance; IT governance maturity; IT governance performance; Enter-prise Architecture; Bayesian networks.; Informatics; computer and systems science; Informatik; data- och systemvetenskap;

    Sammanfattning : Contemporary enterprises are largely dependent on Information Technology (IT), which makes decision making on IT matters important. There are numerous issues that confuse IT decision making, including contradictive business needs, financial constraints, lack of communication between business and IT stakeholders and difficulty in understanding the often heterogeneous and integrated IT systems.

  5. 9. Statistical Downscaling of Precipitation from Large-scale Atmospheric Circulation : Comparison of Methods and Climate Regions

    Författare :Fredrik Wetterhall; Sven Halldin; Chong-Yu Xu; Lars-Christer Lundin; Deliang Chen; Hans von Storch; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Statistical; Downscaling; Precipitation; Large-scale circulation; PCA; TWS; Weather pattern; Regression; Weather generator; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : A global climate change may have large impacts on water resources on regional and global scales. General circulation models (GCMs) are the most used tools to evaluate climate-change scenarios on a global scale. They are, however, insufficiently describing the effects at the local scale. LÄS MER

  7. 10. Performance Analysis of Application-Specific Multicore Systems on Chip

    Författare :Iyad Al Khatib; Axel Jantsch; Jari Nurmi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multicore; System on Chip; Performance; Information technology; Informationsteknik;

    Sammanfattning : The last two decades have witnessed the birth of revolutionary technologies in data communications including wireless technologies, System on Chip (SoC), Multi Processor SoC (MPSoC), Network on Chip (NoC), and more. At the same time we have witnessed that performance does not always keep pace with expectations in many services like multimediaservices and biomedical applications. LÄS MER
