  2. 1. Designing Information Systems : A pragmatic account

    Author : Jonas Sjöström; Pär Johan Ågerfalk; Göran Goldkuhl; Else Nygren; Richard Baskerville; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; information systems; design; pragmatism; design research; it artefact; Informatics and systems science; Informatik och systemvetenskap; Computer and systems science; Data- och systemvetenskap; Informatics; Informatik; Data- och systemvetenskap; Computer Systems Sciences;

    Abstract : Information technology (IT) plays an increasingly important role for individuals, organizations, markets, and society as a whole. IT systems are artefacts (human made objects) designed for various purposes. READ MORE

  4. 2. Self-Management for Large-Scale Distributed Systems

    Author : Ahmad Al-Shishtawy; Vlassov Vlassov; Seif Haridi; Per Brand; Leandro Navarro Moldes; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURAL SCIENCES; NATURVETENSKAP; Self-Management; Autonomic Computing; Control Theory; Distributed Systems; Grid Computing; Cloud Computing; Elastic Services; Key-Value Stores; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Autonomic computing aims at making computing systems self-managing by using autonomic managers in order to reduce obstacles caused by management complexity. This thesis presents results of research on self-management for large-scale distributed systems. READ MORE

  5. 3. 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.

  6. 4. Distributed Peer Discovery in Large-Scale P2P Streaming Systems : Addressing Practical Problems of P2P Deployments on the Open Internet

    Author : Raul Jimenez; Seif Haridi; Björn Knutsson; Arnaud Legout; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Peer-to-peer (P2P) techniques allow users with limited resources to distribute content to a potentially large audience by turning passive clients into peers. Peers can self-organize to distribute content to each other, increasing the scalability of the system and decreasing the publisher’s costs, compared to a publisher distributing the data himself using a content delivery network (CDN) or his own servers.

  7. 5. 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
