  2. 11. Drying of Multicomponent Liquid Films

    Author : Fabio Luna; KTH; []
    Keywords : ternary mixture; falling film; diffusion equation; gas-phase control; liquid-phase control; selectivity; stability analysis; polymeric solution; evaporation; azeotrope; batch drying; continuous drying;

    Abstract : The convective drying of thin layers of multicomponentliquid mixtures into an inert gas, and the influence ofdifferent process controlling mechanisms on drying selectivityis studied. Drying experiments under gas-phase-controlledconditions are performed by low intensity evaporation, fromfree liquid surfaces, of ternary mixtures without non-volatilesolutes. READ MORE

  4. 12. Diffusion of systemic innovations in the construction sector

    Author : John Lindgren; Stephen Emmitt; Kristian Widén; Fawzi Halila; Jack Goulding; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Sector; Innovation Diffusion; Systemic Innovation; Knowledge Integration; Knowledge Development;

    Abstract : The amount of research dealing with innovation has increased dramatically, construction management research included. This thesis focuses on innovations with inter-organizational effects, systemic innovations, which may radically change and improve the construction process. READ MORE

  5. 13. Flamelet modelling of soot formation in diffusion flames

    Author : Anne Simone Dederichs; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Emissions; Pollution; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar diffusion flames than in turbulent ones. READ MORE

  6. 14. Model reduction for diffusion systems

    Author : Bharath Bhikkaji; Torsten Söderström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Abstract : Diffusion phenomena has been studied with a lot of interest, for a long time, due to its historical and practical significance. In the recent days it has thrown a lot of interest among control engineers, as more and more practical systems, varying from stock markets to environmental pollution, have been observed to involve diffusion.

  7. 15. On Scalable H-infinity Control

    Author : Carolina Lidström; Institutionen för reglerteknik; []
    Keywords : ;

    Abstract : Many of the classical approaches to controller synthesis do not scale well for large and complex systems. This is mainly due to computational complexity and the lack of distributed structure in the resulting controllers. READ MORE
