  1. 1. Multi-Sensor Data Synchronization using Mobile Phones

    Författare :Jonas Wåhslén; Thomas Lindh; Jens Eliason; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless body sensor networks; wireless personal area network; sport technology; Bluetooth performance; time synchronization; data fusion; mobile phone application.;

    Sammanfattning : Body sensor networking is a rapidly growing technology. Today wearable sensors are used to measure and monitor e.g. pulse, temperature, skin conductance, heart activity, and movement (through GPS or inertial measurement units). LÄS MER

  3. 2. Bringing Augmented Reality to Mobile Phones

    Författare :Anders Henrysson; Anders Ynnerman; Kari Pulli; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile Phone; Augmented Reality; HCI; Ubiquitous Computing; 3D Interaction; Computer Vision; Image analysis; Bildanalys;

    Sammanfattning : With its mixing of real and virtual, Augmented Reality (AR) is a technology that has attracted lots of attention from the science community and is seen as a perfect way to visualize context-related information. Computer generated graphics is presented to the user overlaid and registered with the real world and hence augmenting it. LÄS MER

  4. 3. Mode choice modelling of long-distance passenger transport based on mobile phone network data

    Författare :Angelica Andersson; Maria Börjesson; Ida Kristoffersson; Clas Rydergren; Leonid Engelson; Jonas Westin; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand model; Mode choice; Latent class; Mobile phone network data; Travel behaviour; Long-distance travel;

    Sammanfattning : Reliable forecasting models are needed to achieve the climate related goals in the face of increasing transport demand. Such models can predict the long-term behavioural response to policy interventions, including infrastructure investments, and thus provide valuable pre-dictions for decision makers. LÄS MER

  5. 4. Large scale and mobile group communication systems

    Författare :Roland Parviainen; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distribuerade datorsystem; Mobile and Pervasive Computing;

    Sammanfattning : This doctoral thesis examines different attributes of large scale group communication systems such as scalability, security and mobility by studying two different prototype systems - mIR (multicast Interactive Radio) and MES (Mobile E-meeting Services). mIR is a system for large scale real-time music distribution, designed as an interactive radio system for the Internet.

  7. 5. Studies of Three Different Methods to Estimate the Up-link Performance of Mobile Phone Antennas

    Författare :Sathyaveer Prasad; Peter Händel; Claes Beckman; Jan Carlsson; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna measurements; mobile phones; total radiated power; reverberation chamber; anechoic chamber; Telia Scattered Field Method; Maximum likelihood Estimator; Telecommunication; Telekommunikation;

    Sammanfattning : Antennas play an important role in determining the overall radio performance for wireless communications. If all other radio components perform according to their specifications, the performance of a mobile phone can be entirely determined by measuring the efficiency of its antenna. LÄS MER
