  1. 16. Computer Experiments Designed to Explore and Approximate Complex Deterministic Models

    Författare :Davood Shahsavani; Anders Grimvall; Stefano Tarantola; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; computer and systems science; Statistik; data- och systemvetenskap;

    Sammanfattning : Computer experiments are widely used to investigate how technical, economic, and ecological systems respond to changes in inputs or driving forces. This thesis is focused on design of computer experiments that can help us better understand the output from complex computer code models. LÄS MER

  3. 17. Statistical Methods for Computational Markets : Proportional Share Market Prediction and Admission Control

    Författare :Thomas Sandholm; Magnus Boman; Mark Baker; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Grid Computing; Performance Analysis; Workload Modeling; Middleware; Quality of Service; Prediction; Admission Control; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. LÄS MER

  4. 18. Essays on financial time series models : Stochastic volatility and long memory

    Författare :Jonas Andersson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; statistik; Statistics;

    Sammanfattning : This work consists of five articles about the statistical aspects of financial time series models. The first three papers investigate and develop the inverse normal Gaussian stochastic volatility (NIGSV) model, initially suggested by Barndorff- Nielsen (1997). LÄS MER

  5. 19. Safety-oriented communication in mobile networks for vehicles

    Författare :Ioan Chisalita; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vehicular communication; active safety systems; collision warning and avoidance; safety-related information; Computer science; Datavetenskap;

    Sammanfattning : Accident statistics indicate that every year a large number of casualties and extensive property losses are recorded due to traffic accidents. Consequently, efforts are directed towards developing passive and active safety systems that help reducing the severity of crashes or prevent vehicles to collide with each other. LÄS MER

  7. 20. Resource Lean and Portable Automatic Text Summarization

    Författare :Martin Hassel; Hercules Dalianis; Viggo Kann; Kerstin Severinson Eklundh; Horacio Saggion; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; holsum; language independent; holistic; summarization; lexical semantics; co-occurrence statistics; word space model; bag-of-words; bag-of-concepts; random indexing; swesum; news corpus; extract corpus; Computer science; Datalogi;

    Sammanfattning : Today, with digitally stored information available in abundance, even for many minor languages, this information must by some means be filtered and extracted in order to avoid drowning in it. Automatic summarization is one such technique, where a computer summarizes a longer text to a shorter non-rendundant form. LÄS MER
