  1. 11. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale

    Författare :Gustav Silfversparre; KTH; []
    Nyckelord :Large-scale; E.coli; fed batch; concentration gradients; mixing;

    Sammanfattning : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. LÄS MER

  3. 12. Compositional optimization of large-scale discrete event systems

    Författare :Fredrik Hagebring; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Event Systems; Automation; Large-scale optimization; Discrete Optimization; Compositional Optimzation;

    Sammanfattning : Optimization of industrial processes such as manufacturing cells can have great impact on their performance. Finding optimal solutions to these large-scale systems is, however, a complex problem. They typically include multiple subsystems, and the search space generally grows exponentially with each subsystem. LÄS MER

  4. 13. On H-infinity Control and Large-Scale Systems

    Författare :Carolina Bergeling; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity Control; Decentralized Control; Large-Scale Systems; Infinite-Dimensional Systems;

    Sammanfattning : In this thesis, a class of linear time-invariant systems is identified for which a particular type of H-infinity optimal control problem can be solved explicitly. It follows that the synthesized controller can be given on a simple explicit form. LÄS MER

  5. 14. 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. 15. Short-Term Traffic Prediction in Large-Scale Urban Networks

    Författare :Matej Cebecauer; Erik Jenelius; Wilco Burghout; Balázs Kulcsár; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel time prediction; short-term travel time prediction; traffic prediction; clustering; partitioning; spatio-temporal partitioning; large-scale prediction; PPCA; 3D speed map; Transportvetenskap; Transport Science;

    Sammanfattning : City-wide travel time prediction in real-time is an important enabler for efficient use of the road network. It can be used in traveler information to enable more efficient routing of individual vehicles as well as decision support for traffic management applications such as directed information campaigns or incident management.
