  1. 11. Developments in Feedstock Analysis and Process Control for Biogas Production

    Author : Sten Strömberg; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Abstract : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. READ MORE

  2. 12. Sensing and Control of Dynamical Systems Over Networks

    Author : Ali Abbas Zaidi; Mikael Skoglund; Tobias J. Oechtering; Nuno Martins; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Rapid advances in sensing, computing, and wireless technologies have led to significant interest in the understanding and development of wireless networked control systems. Networked control systems consist of spatially distributed agents such as plants (dynamical systems), sensors, and controllers, that interact to achieve desired objectives. READ MORE

  3. 13. Of Pipes and Bends

    Author : Jacopo Canton; Philipp Schlatter; Ramis Örlü; Dwight Barkley; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear instability; bifurcation; flow control; Engineering Mechanics; Teknisk mekanik;

    Abstract : This work is concerned with the transition to turbulence of the flow in bent pipes, but it also includes an analysis of large-scale turbulent structures and their use for flow control.The flow in a toroidal pipe is selected as it represents the common asymptotic limit between spatially developing and helical pipes.

  4. 14. Effects of Flow Structure on Particle Separation in Dissolved Air Flotation

    Author : Måns Lundh; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; Teknik; Technological sciences; modelling; retention time distribution; acoustic doppler velocimeter; flow structure; separation; water treatment; wastewater treatment;

    Abstract : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

  5. 15. Metabolism-dependent taxis and control of motility in Pseudomonas putida

    Author : Sofia Österberg; Vicky Shingler; Caroline Harwood; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Motility; c-di-GMP; metabolism-dependent taxis; receptors; transcription; Pseudomonas putida; molekylärbiologi; Molecular Biology;

    Abstract : Bacteria living in soil and aquatic habitats rapidly adapt to changes in physico-chemical parameters that influence their energy status and thus their ability to proliferate and survive. One immediate survival strategy is to relocate to more metabolically optimal environments. READ MORE
