  3. 17. Statistical advancements in analyzing accelerometer-measured physical activity intensity

    Författare :Jonatan Fridolfsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; accelerometry; cardiometabolic risk factors; cardiovascular disease; cardiorespiratory fitness; public health; statistics; multivariate; partial least squares; structural equation modelling;

    Sammanfattning : Physical activity (PA) is widely recognized as an important factor in preventing and treating cardiometabolic diseases and reducing mortality. Yet, the health implications of specific PA intensities and the intricate role of fitness in the relationship between PA and health remain less clear. LÄS MER

  7. 20. Rock Mass Characterisation Using Drill Performance Monitoring : Problems, Analysis challenges and Limitations

    Författare :Rajib Ghosh; Piyush Rai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : In open pit mining, it is important to know as much information as possible about rock masses to be mined for more cost-effective mining operation. In rock engineering perspective, information about rock mass characteristics usually includes hardness of the rock, geological features, fractures, faults, ore contacts, water bearing stratum. LÄS MER
