  1. 1. Inducing large-scale diffusion of innovation : An integrated actor- and system-level approach

    Author : Ingrid Mignon; Anna Bergek; Johanna Nählinder; Volker Hoffmann; Linköpings universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; SOCIAL SCIENCES; Innovation; large-scale diffusion; adopters; actor; system; drivers; challenges; motives; strategies; policies; renewable electricity; technology; intermediaries;

    Abstract : In order for the innovation process to be successful, not only do innovations need to be developed and reached the market, but, once they are available for users, they have to spread on a large scale. In the innovation literature, a complete explanation is lacking of why some innovations reach a phase of large-scale diffusion faster than others, including both actor- and system-level components.

  2. 2. On H-infinity Control and Large-Scale Systems

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

    Abstract : 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. READ MORE

  3. 3. Analysis of Binding Events and Diffusion in Living Cells

    Author : Markus Elsner; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : COPI; Golgi; Diffusion; Glycosyltransferases; Sorting; Molecular; Crowding;

    Abstract : It is well known that diffusion is the main mode of transport in living cells, but the consequences of diffusion in a complex cellular environment are not generally appreciated. In this thesis, we have investigated several aspects of how diffusion properties influence the observability of cellular binding kinetics and how they can be used to obtain information about the environment of proteins and other molecules.

  4. 4. Reaction and Diffusion Phenomena in Biomimetic Nanoscale Reactors and Networks

    Author : Kristin Sott; Chalmers University of Technology; []
    Keywords : artificial cell; restricted geometries.; enzymatic reactions; micromanipulation; biomimetic; nanotubes; diffusion; Vesicles; networks; liposomes;

    Abstract : Methods for construction of geometrically complex, fully connected surface-immobilized microscopic networks of phospholipid bilayer vesicles (1-50 µm in diameter) interconnected by lipid nanotubes (100-300 nm in diameter), have been developed. The networks have controlled connectivity and are well-defined with regard to the container size, content, angle between nanotube extensions, and nanotube length. READ MORE

  5. 5. Flow processing and gel formation for producing biopolymer drops with functional shapes and diffusion properties

    Author : Bernhard Walther; Chalmers University of Technology; []
    Keywords : drop deformation; 4-roll mill; biopolymer; agarose; shear; Kappa-carrageenan; elongation; microstructure; flow processing; drop-shaping; rheology; poly ethyleneglycol ; diffusion; gelatine; NMR; gel formation; TEM; flow channel;

    Abstract : This thesis focuses on the development of novel processes which combine flow-induced drop deformation and simultaneous temperature-induced gel formation in order to create shaped biopolymer drops. The drops are functional in terms of rheology and diffusion properties, factors strongly influencing the consistency of food products and flavour or drug release. READ MORE
