  2. 1. Real-Time Optimization of Cone Crushers

    Author : Erik Hulthén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process optimization; crushing; CSS; real-time optimization; eccentric speed; cone crusher;

    Abstract : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation and production of rock materials. Cone crusher control systems are widely used for machine protection, wear compensation and, to some extent, increasing production. These systems ordinarily focus on the crusher and not the yield of production process. READ MORE

  4. 2. Muscle injury and pain : effects of eccentric exercise, sprint running, forward lunge and sports massage

    Author : Sven Jönhagen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Muscle injury; muscle pain; DOMS; eccentric; massage; sprint runner; EMG;

    Abstract : Muscle injuries are the most common injury in sports and both athletes and non-athletes are commonly seen in general practice and in the emergency department. Muscle pain is a common cause for absence from work and the cost to society is high. READ MORE

  5. 3. Velocity controlled dynamometry and gait analysis : development of methods and applications

    Author : Lennart Gransberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Dynamometry; torque; measurement error; overshoot; isokinetic; concentric; eccentric; gait analysis; three-dimensional; electrogoniometer; electromagnetic tracking;

    Abstract : The isokinetic systems developed in the present study can measure torque in maximal voluntary and passive movements. The torque recordings may be combined with surface EMG recordings from pairs of antagonistic muscles involved in the movement. Healthy subjects and patients with spastic paresis have been examined.

  6. 4. Asymmetric lateral loading of the human trunk

    Author : Qiang-Min Huang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Eccentric; concentric; isokinetic; electromyography; co-activation; trunk; spinal biomechanics; contraction patterns; lateral bending; lifting and lowering; balance; kinematics; postural control; IAP; support translation.;

    Abstract : The overall aim of this thesis was to characterize the biomechanics and neuromuscular control of the human trunk in response to asymmetric lateral loading. The pulling force and strength capacities as well as muscle activation patterns, trunk kinematics and postural balance in relation to lateral trunk flexion and loading were given special consideration.

  7. 5. REAL TIME OPTIMIZATION OF ROCK CRUSHERS

    Author : Erik Hulthén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crushing plant; cone crusher; real time optimization; rock crusher;

    Abstract : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materials. Cone crusher control systems are widely used for wear compensation and machine protection. These systems ordinarily focus on the crusher and not the crushed products. READ MORE
