  1. 1. Cooperative Communications : Link Reliability and Power Efficiency

    Author : Tafzeel ur Rehman Ahsin; Ben Slimane; Xavier Lagrange; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. READ MORE

    Abstract : In response to technological advances, especially in the field of information and communication technology (ICT), the so called revolution in military affairs (RMA) and later the concept of network-centric warfare (NCW) emerged as a theory to further utilize technology for military command and control (C2). Advocates of the Swedish ROLF 2010-vision and the concept of NCW have made claims and assumptions that future technology will improve mission effectiveness by, for example, increasing the understanding of a current situation and its development, the speed of command, and providing means to utilize more efficient forms of organizations.

  3. 3. Opinion-Based Systems : The Cooperative Perspective on Knowledge-Based Decision Support

    Author : Göran Forslund; Linköpings universitet; []

    Abstract : During the last fifteen years expert systems have successfully been applied to a number of difficult problems in a variety of different application domains. Still, the task of actually developing these systems has been much harder than was predicted, and among systems delivered many have failed to meet user acceptance. READ MORE

  4. 4. Supporting the Cooperative Design Process of End-User Tailoring

    Author : Jeanette Eriksson; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; End-user tailoring; Software evolution; Participatory design;

    Abstract : In most business areas today, competition is hard and it is a matter of company survival to interpret and follow up changes within the business market. The margin between success and failure is small. Possessing suitable, sustainable information systems is an advantage when attempting to stay in the front line of the business area. READ MORE

  5. 5. Design for Places of Collaboration

    Author : Alexandra Petrakou; Linnéuniversitetet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; NATURAL SCIENCES; NATURVETENSKAP; Boundary Objects; Collaborative Settings; Computer-Supported Cooperative Work CSCW ; Design; Place; Places of Collaboration; Space; Collaboration; Computer-Supported Cooperative Work; Design; Design; Computer Science; Datavetenskap; Information Systems; Informatik;

    Abstract : This thesis reports a research effort that comprises six papers and a cover paper. In essence, the thesis contributes to the understanding of collaborative settings by introducing the perspective of 'places of collaboration‘. This perspective is particularly important when designing computer-based technologies that support collaborative settings. READ MORE
