  1. 11. On Spectrum Sensing for Secondary Operation in Licensed Spectrum : Blind Sensing, Sensing Optimization and Traffic Modeling

    Författare :Mohamed Hamid; Ben Slimane Slimane; Niclas Björsell; Octavia Dobre; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cognitive Radio; Spectrum Sensing; Sensing Optimization; Blind Sensing; Traffic Modelling; Energy detection; Maximumum-minimum Eigenvalue Detection; Discriminant anlysis; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : There has been a recent explosive growth in mobile data consumption. This, in turn, imposes many challenges for mobile services providers and regulators in many aspects. One of these primary challenges is maintaining the radio spectrum to handle the current and upcoming expansion in mobile data traffic. LÄS MER

  3. 12. Embodied Pedagogical Agents: From Visual Impact to Pedagogical Implications

    Författare :Magnus Haake; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; masculinity; role modelling; cognitive styles; stereotypes; education; pedagogical implications; visual style; virtual characters; visual design; Virtual pedagogical agents; femininity; gender; androgynities;

    Sammanfattning : Embodied pedagogical agents – visually represented, computer generated characters in pedagogical roles, such as virtual instructors, mentors and learning companions – populate the digital society in increasing numbers. They are found in educational programmes from preschool to university, as well as in broader educational contexts in the form of medical counsellors, virtual health coaches, information guides, etc. LÄS MER

  4. 13. Characterisation of inputs and outputs of striatal medium spiny neurons in health and disease

    Författare :Marko Filipović; Jeanette Hellgren Kotaleski; Arvind Kumar; Gilad Silberberg; Ad Aertsen; Andrew Sharott; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; basal ganglia; striatum; medium spiny neurons; subthalamic nucleus; globus pallidus; Parkinson s disease; in vivo; oscillations; spectral analysis; response variability; networks; simulations; modelling; Numerical Analysis; Numerisk analys; Computer Science; Datalogi; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Striatal medium spiny neurons (MSNs) play a crucial role in various motor and cognitive functions. They are separated into those belonging to the direct pathway (dMSNs) and the indirect pathway (iMSNs) of the basal ganglia, depending on whether they express D1 or D2 type dopamine receptors, respectively.

  5. 14. Human-Robot Interaction and Mapping with a Service Robot : Human Augmented Mapping

    Författare :Elin Anna Topp; Henrik I. Christensen; Benjamin J. Kuipers; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Human-Robot Interaction; Cognitive modelling; Representation of space; Computer science; Datavetenskap;

    Sammanfattning : An issue widely discussed in robotics research is the ageing society with its consequences for care-giving institutions and opportunities for developments in the area of service robots and robot companions. The general idea of using robotic systems in a personal or private context to support an independent way of living not only for the elderly but also for the physically impaired is pursued in different ways, ranging from socially oriented robotic pets to mobile assistants.

  7. 15. Having a New Pair of Glasses : Applying Systemic Accident Models on Road Safety

    Författare :Yu-Hsing Huang; Erik Hollnagel; Pietro Carlo Cacciabue; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accident model; road safety; accident prevention; accident analysis; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : The main purpose of the thesis is to discuss the accident models which underlie accident prevention in general and road safety in particular, and the consequences of relying on a particular model have for actual preventive work. The discussion centres on two main topics. LÄS MER
