  2. 26. 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

  4. 27. High Performance Hybrid Memory Systems with 3D-stacked DRAM

    Author : Evangelos Vasilakis; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DRAM caches; Data migration; 3D-stacked DRAM; Hybrid memory systems;

    Abstract : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. READ MORE

    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.

  6. 29. Flexible Composition of Robot Logic with Computer Vision Services

    Author : Oleksandr Semeniuta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; data flow; service-oriented architecture; distributed systems; machine learning; discrete-event systems; Machine vision; publish-subscribe;

    Abstract : Vision-based robotics is an ever-growing field within industrial automation. Demands for greater flexibility and higher quality motivate manufacturing companies to adopt these technologies for such tasks as material handling, assembly, and inspection. READ MORE

  7. 30. Exploiting Energy Awareness in Mobile Communication

    Author : Ekhiotz Jon Vergara Alonso; Simin Nadjm-Tehrani; Daniele Puccinelli; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless transmission energy; energy consumption; mobile devices; power measurements; application energy; data pattern; trace-based simulation;

    Abstract : Although evolving mobile technologies bring millions of users closer to the vision of information anywhere-anytime, device battery depletions hamper the quality of experience to a great extent. The massive explosion of mobile applications with the ensuing data exchange over the cellular infrastructure is not only a blessing to the mobile user, but also has a price in terms of rapid discharge of the device battery.
