  2. 1. On the effect of repetitive loading on the spine of young elite athletes. Clinical and experimental studies

    Author : Olof Thoreson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spine; intervertebral disc; athlete; young adult; low back pain; magnetic resonance imaging; porcine; repetitive loading; failure; fatigue;

    Abstract : Introduction: The human spine is exposed to many different loads during daily activities and especially during sporting activities. The spine has different biomechanical properties during the lifetime and thereby responds differently to repetitive and sudden loads. READ MORE

  4. 2. Automation of Navigation During the Short-loading Cycle Using Machine Vision

    Author : Carl Borngrund; Ulf Bodin; Fredrik Sandin; Jerker Delsing; Henrik Andreasson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Automation; Short-loading cycle; Construction equipment; Deep Learning; Computer Vision; Cyber-Physical Systems; Cyberfysiska system;

    Abstract : Earth-moving machines are machines used in a wide range of industries, such as the construction industry, to perform tasks related to earthworks.Currently, the vast majority of earth-moving machines are human-operated where expert operators perform these industry vital tasks.

  5. 3. Towards Deep-learning-based Autonomous Navigation in the Short-loading Cycle

    Author : Carl Borngrund; Ulf Bodin; Fredrik Sandin; Henrik Andreasson; Jerker Delsing; Juha Röning; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyberfysiska system; Cyber-Physical Systems;

    Abstract : Earth-moving machines, such as wheel loaders, are a type of heavy-duty machinery used within the construction industry to perform vital tasks, such as digging, transporting, and mining applications. One of these tasks is the short-loading cycle, where an operator manoeuvres the wheel loader to move material from a pile to the tipping body of a dump truck, through navigation, scooping, and dumping.

  6. 4. On methods of evaluation of lower extremity eccentric muscle performance and loading

    Author : Pär Westblad; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Biomechanics; eccentric; electromyography; isokinetic; methods; muscle endurance; pilot projects; reproducibility of results; strain; thigh; tibia.;

    Abstract : This investigation has developed and evaluated methods for measuring eccentric muscle function and loading of the human lower extremity, including isokinetic tests of knee extensor muscle performance and a comprehensive in vivo method for conditions of functional loading. For measurement of knee extensor muscle performance, a protocol of 100 repetitive maximal actions at 90° was applied using a Biodex isokinetic dynamometer. READ MORE

  7. 5. Modeling and Optimal Control of Heavy-Duty Powertrains

    Author : Vaheed Nezhadali; Lars Eriksson; Giorgio Rizzoni; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Powertrain; transmission system; optimal control; modeling for control;

    Abstract : Heavy duty powertrains are complex systems with components from various domains, different response times during transient operations and different efficient operating ranges. To ensure efficient transient operation of a powertrain, e.g. READ MORE
