  1. 1. Designing Information Systems : A pragmatic account

    Författare :Jonas Sjöström; Pär Johan Ågerfalk; Göran Goldkuhl; Else Nygren; Richard Baskerville; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

    Författare :Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

    Sammanfattning : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. LÄS MER

  5. 4. Enabling Scalable Security in Internet of Things

    Författare :Zhitao He; Thiemo Voigt; Shahid Raza; Per Gunningberg; Mário Alves; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internet of Things; Wireless Sensor Networks; Radio Interference; Denial-of-service Attacks; Public Key Infrastructure; Electrical Engineering with Specialisation in Networked Embedded Systems; Elektroteknik med inriktning mot nätverksbaserade inbyggda system;

    Sammanfattning : The popular notion of Internet of Things (IoT) implies two salient features: 1. a diversity of small things, i.e., constrained devices; 2. LÄS MER

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

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

    Sammanfattning : 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.
