  1. 1. Manual Motor Development in Infancy : Execution and Observation of Actions

    Author : Therese Ljunghammar Ekberg; Gustaf Gredebäck; Claes von Hofsten; Jeffrey J. Lockman; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Infancy; Motor development; Reaching; Actions; Motor prediction; Prospective motor control; Social cognition; Stereopsis; Mirror neuron system; Mu rhythm; Motor impairment; Autism Spectrum Disorder; High-risk siblings; Psychology; Psykologi;

    Abstract : Of all motor skills, manual reaching might be the one ability that matters most for infants’ perceptual, cognitive and social development. Reaching allows infants to learn about object properties, but also gives opportunities for socializing with others. READ MORE

  2. 2. Design and Evaluation of a Compact 15 kW PM Integral Motor

    Author : Peter Thelin; KTH; []
    Keywords : integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

    Abstract : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. READ MORE

  3. 3. Stochastic modeling of motor proteins

    Author : Martin Lindén; Mats Wallin; Dean Astumian; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; molecular motor; motor protein; Markov process; fluctuations; statistical mechanics; microscopic reversibility; Physics; Fysik;

    Abstract : Motor proteins are microscopic biological machines that convert chemical energy into mechanical motion and work. They power a diverse range of biological processes, for example the swimming and crawling motion of bacteria, intracellular transport, and muscle contraction. READ MORE

  4. 4. Motion interactive games for children with motor disorders : motivation, physical activity, and motor control

    Author : Marlene Sandlund; Charlotte Häger; Eva Lindh Waterworth; Lena-Karin Erlandsson; Ann-Christin Eliasson; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Children; parents; cerebral palsy; physical training; home training; motivation; physical activity; motor control; virtual reality; video games.; Physiotherapy; Sjukgymnastik fysioterapi; sjukgymnastik; Physiotherapy;

    Abstract : As motion interactive games have become more widespread the interest in using these games in rehabilitation of children with motor disorders has increased among both clinical professionals and the families of these children. The general aim of this thesis was to evaluate the feasibility of using interactive games in rehabilitation of children to promote motivation for practice, physical activity, and motor control.

  5. 5. Muscle Thixotropy : Implications for Human Motor Control

    Author : Hans Axelson; Karl-Erik Hagbarth; Mikael Elam; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Motor control; Skeletal muscle; Thixotropy; History-dependent; EMG; Voluntary contractions; Neurovetenskap; Neurology; Neurologi;

    Abstract : Human skeletal muscles possess thixotropic, i.e. history-dependent mechanical properties. This means that the degree of passive muscle stiffness and resting tension is dependent on the immediately preceding history of contractions and length changes. READ MORE
