    Author : Simon Lindroth [formerly Tyrberg]; Mats Leijon; Brian Holmes; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; Measurement systems; Marine technology; Energy conversion; Renewable energy; Energy absorption; Wave resource; Oceanic engineering; Linear generators; Point absorbers; Sea trials; Camera systems; Accelerometers; Offshore experiments; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

  4. 2. Gait Event Detection in the Real World

    Author : Siddhartha Khandelwal; Nicholas Wickström; Thorsteinn Rögnvaldsson; Brian Caulfield; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gait analysis; gait event detection; wearable sensors; accelerometers;

    Abstract : Healthy gait requires a balance between various neuro-physiological systems and is considered an important indicator of a subject's physical and cognitive health status. As such, health-related applications would immensely benefit by performing long-term or continuous monitoring of subjects' gait in their natural environment and everyday lives. READ MORE

  5. 3. Micromachined Three-Axis Accelerometers and Sensor Readout Electronics

    Author : Henrik Rödjegård; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three axis accelerometer; sensor readout; inertial sensors; gyroscope; MEMS; digital feedback; capacitive readout;

    Abstract : Miniaturized, MEMS-based, inertial navigation systems are used to track the position of moving objects without an external reference system. Several existing and future applications such as indoor navigation, stability control of vehicles, active prostheses or training aids for sportsmen would benefit from the small size and the low cost of micromachined inertial sensors.

  6. 4. Vibroacoustic performance of wooden buildings : Prediction and Perception

    Author : Juan Negreira; Teknisk akustik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction tools; Low frequency vibrations; Vibroacoustics; Wooden buildings; Impact sound insulation; Finite element method; Vibration measurements; Flanking transmission; Elastomers; Design indicators; Vibration acceptability; Vibration annoyance; MEMS accelerometers;

    Abstract : When the Swedish building regulations in 1994 allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. READ MORE
