  1. 1. Assessment of active commuting behaviour : walking and bicycling in Greater Stockholm

    Författare :Erik Stigell; Peter Schantz; Andreas Nilsson; Maria Hagströmer; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; walking; cycling; commuting; validity; reproducibility; distance; duration; velocity; frequency; seasonality; Sports; Idrott; Samhällsvetenskap Humaniora; Social Sciences Humanities; Sports Science;

    Sammanfattning : Walking and bicycling to work, active commuting, can contribute to sustainable mobility and provide regular health-enhancing physical activity for individuals. Our knowledge of active commuting behaviours in general and in different mode and gender groups in particular is limited. LÄS MER

  3. 2. Active school transportation : Understanding the parental decision-making process

    Sammanfattning : Few children and adolescents reach the recommended levels of daily physical activity. This trend is evident in the countries examined in this thesis: Sweden and Spain. LÄS MER

  4. 3. Capabilities of Convolutional Codes: Unequal Error Protection and More

    Författare :Victor Pavlushkov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektronik och elektroteknik; Electronics and Electrical technology; systemteori; Informatik; Informatics; systems theory; woven codes; unequal error protection; active input-distance; active output-distance; maximum slope; active distances; Convolutional codes; error-correcting capability;

    Sammanfattning : Many communication systems obtain enhanced performance by using concatenated coding schemes. Turbo codes and woven convolutional codes are two examples of such schemes. LÄS MER

  5. 4. Towards energy efficient protocols for active RFID

    Författare :Björn Nilsson; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RFID; active RFID; protocol; back-off; carrier sense; energy efficient; wireless networks; active tag; energy consumption; Computer engineering; Datorteknik;

    Sammanfattning : The absence of a global standard is a bottleneck when using Radio Frequency Identification (RFID) technology. This thesis explores data communication protocols for Active-RFID regarding their energy efficiency and how they can be suited to fit a large variety of applications. LÄS MER

  7. 5. Tales of Tailbiting Codes

    Författare :Marc Handlery; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum-likelihood decoding algorithm; minimum distance; active distance; woven convolutional code; tailbiting termination method; convolutional code; tailbiting code; Informatics; systems theory; Informatik; systemteori;

    Sammanfattning : Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. LÄS MER
