  1. 1. The effectiveness of a full-mobility architecture for wireless mobile computing and personal communications

    Författare :George Yuejin Liu; Gerald Maguire; Randy Katz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile Computing; Mobile-API; Mobile Agent; Mobile Floating Agent; Intelligent Agent; Full-Mobility; Mobility Architecture; Mobility Awareness; Location Awareness; Location Prediction; Mobile Personal Communications.;

    Sammanfattning : The emergence of wireless mobile computing, especially the mobility of computers, introduces challenging new problems that were encountered in neither the design and implementation of conventional mobile networks or in fixed computer networks. A critical and challenging problem, for mobile computing and personal communications, is how to fully cope with the special characteristics of the mobile wireless environment, i. LÄS MER

  3. 2. Multi-Agent Mission Planning

    Författare :Branko Miloradović; Alessandro Papadopoulos; Baran Curuklu; Mikael Ekström; Luis Merino; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Multi-Agent Systems (MASs) have been utilized in various settings and frameworks, and have thus been successfully applied in many applications to achieve different goals. It has been shown that MASs are more cost-effective as compared to building a single agent with all the capabilities a mission may require. LÄS MER

    Sammanfattning : In both physical and virtual environments, small group interactions significantly shape our social experiences. Understanding and replicating situated group interactions with virtual agents or physical robots pose possibilities and challenges. LÄS MER

  7. 5. Expressiveness in virtual talking faces

    Författare :Gunilla Svanfeldt; Björn Granström; Francisco Lacerda; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Language technology; Språkteknologi;

    Sammanfattning : In this thesis, different aspects concerning how to make synthetic talking faces more expressive have been studied. How can we collect data for the studies, how is the lip articulation affected by expressive speech, can the recorded data be used interchangeably in different face models, can we use eye movements in the agent for communicative purposes? The work of this thesis includes studies of these questions and also an experiment using a talking head as a complement to a targeted audio device, in order to increase the intelligibility of the speech.
