  3. 7. Building a coherent hydro-climatic modelling framework for the data limited Kilombero Valley of Tanzania

    Författare :Alexander Koutsouris; Steve W. Lyon; Jan Seibert; Mekonnen Gebremichael; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Recession analysis; End - member mixing analysis; EMMA; GLUE; HBV; down scaling; Quantile mapping; CFSR; CMORPH; CRU; GPCC; ERA - i; MERRA; TRMM; UDEL; Satellite; Reanalysis; Kilombero; Tanzania; Eastern Africa; Africa; Physical Geography; naturgeografi;

    Sammanfattning : This thesis explores key aspects for synthesizing data across spatiotemporal scales relevant for water resources management in an Eastern Africa context. Specifically, the potential of large scale global precipitation datasets (GPDs) in data limited regions to overcome spatial and temporal data gaps is considered. LÄS MER

  4. 8. Some Results On Optimal Control for Nonlinear Descriptor Systems

    Författare :Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []

    Sammanfattning : I denna avhandling studeras optimal återkopplad styrning av olinjära deskriptorsystem. Ett deskriptorsystem är en matematisk beskrivning som kan innehålla både differentialekvationer och algebraiska ekvationer. LÄS MER

  5. 9. On Kinematic Modelling and Iterative Learning Control of Industrial Robots

    Författare :Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Geir Hovland; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; kinematics; Maple; modelling; iterative learning control; experiments; Automatic control; Reglerteknik;

    Sammanfattning : Good models of industrial robots are necessary in a variety of applications, such as mechanical design, performance simulation, control, diagnosis, supervision and offline programming. This motivates the need for good modelling tools. In the first part of this thesis the forward kinematic modelling of serial industrial robots is studied. LÄS MER

  7. 10. Modeling nutrient cycling and sustainable forest growth in a changing world

    Författare :Patrik Wallman; LUCSUS; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nutrients; sustainability; ForSAFE; Chemical technology and engineering; forestry technology; forestry; Silviculture; system dynamics; forest growth models; dynamic modeling; Kemiteknik och kemisk teknologi; skogsbruk; skogsteknik; Skogsvetenskap;

    Sammanfattning : It took 70-80 years to realize the width of the impact of industrialization on the forest ecosystems since a forest ecosystem is a "slow system" as seen from a human perspective. An anticipated future climate change and increasing carbon dioxide and ozone levels will change the conditions even more with time and the widely used statistical forest growth models will not be applicable anymore.
