  2. 11. Dynamic enforcement of decentralized security policies

    Author : Jonas Magazinius; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamic; enforcement; security; policies; decentralized;

    Abstract : This thesis explores defining security policies in a decentralized setting and dynamic methods of enforcing such policies. In a decentralized setting, principals are free to trust or distrust other principals. The key challenge is to provide possibilities for expressing and enforcing expressive decentralized policies.

  4. 12. Dynamic Sulfur Chemistry : Screening, Evaluation and Catalysis

    Author : Rémi Caraballo; Olof Ramström; Nicolas Giuseppone; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dynamic combinatorial chemistry; dynamic sulfur chemistry; thioglycoside; mutarotation; disulfide metathesis; hemithioacetal formation; 1H STD-NMR; inhibition; phosphine; Concanavalin A; beta-galactosidase; dynamic drug discovery.; Chemistry; Kemi; Organic chemistry; Organisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Abstract : This thesis deals with the design, formation and evaluation of dynamic systems constructed by means of sulfur-containing reversible reactions, in organic and aqueous media and under mild conditions. In a first part, the synthesis of thioglycoside derivatives, constituting the biologically relevant starting components of the dynamic systems, is described. READ MORE

  5. 13. Diffusion of dynamic innovations : A case study of residential solar PV systems

    Author : Emrah Karakaya; Cali Nuur; Antonio Hidalgo; Anna Bergek; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dynamic innovations; diffusion; residential solar; photovoltaics; time; space; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Abstract : In the literature on diffusion of innovations, it is widely known that the characteristics and socio-environmental settings of adopters do evolve in space and time. What about innovations themselves? During the diffusion process, don’t some innovations continuously alter in space and time? If so, how does the dynamic character of an innovation influence the diffusion process? In previous research, it has been often assumed that innovations do not continuously alter or get modified when diffusing from a source to potential adopters. READ MORE

  6. 14. Dynamic and meta-dynamic recrystallization of Ni-based superalloy Haynes 282

    Author : Emil Eriksson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot compression; EBSD; dynamic recrystallization; meta-dynamic recrystallization; Ni-base superalloys;

    Abstract : Thermomechanical processes are a crucial manufacturing step because they can “reset” the microstructure, and set the starting point for all following steps. In turn, the microstructure can be used to tailor the mechanical properties of the material. READ MORE

  7. 15. Modeling Complex Engines as Dynamic Powertrain Members

    Author : Sixten Berglund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle; diesel engine; simulation; supercharging; drivability; toolbox; fuel economy; transient; modeling; turbocharging; control system; powertrain; emissions; performance; dynamic; system;

    Abstract : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. READ MORE
