    Abstract : The contemporary computers typically consist of multiple computing cores with high compute power. Such computers make excellent concurrent asynchronous shared memory system. READ MORE

  4. 2. Information Systems Actability : Understanding Information Technology as a Tool for Business Action and Communication

    Author : Pär J. Ågerfalk; Göran Goldkuhl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; information systems; information systems actability; Internet-based information systems; language action perspective; Information technology; Informationsteknologi;

    Abstract : This dissertation is devoted to a perspective from which IT-based information systems are conceived as information technological artefacts intended for business action and communication. The perspective has been made concrete through the concept of information systems actability, which is the main concept under scrutiny. READ MORE

  5. 3. Talk the walk : Empirical studies and data-driven methods for geographical natural language applications

    Author : Jana Götze; Johan Boye; Martin Raubal; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pedestrian wayfinding; salience; route instructions; reference resolution; Computer Science; Datalogi;

    Abstract : Finding the way in known and unknown city environments is a task that all pedestrians carry out regularly. Current technology allows the use of smart devices as aids that can give automatic verbal route directions on the basis of the pedestrian's current position. READ MORE

  6. 4. Design of Energy-Efficient High-Performance ASIP-DSP Platforms

    Author : Andréas Karlsson; Dake Liu; Andreas Ehliar; Jarmo Takala; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In the last ten years, limited clock frequency scaling and increasing power density has shifted IC design focus towards parallelism, heterogeneity and energy efficiency. Improving energy efficiency is by no means simple and it calls for a reevaluation of old design choices in processor architecture, and perhaps more importantly, development of new programming methodologies that exploit the features of modern architectures.

    Abstract : During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing.
