The ability to measure six degrees of freedom (6 DOF) head kinematics in motor vehicle crash conditions is important for assessing head-neck loads as well as brain injuries. A method for obtaining accurate 6 DOF head kinematics in short duration impact conditions is proposed and validated in this study. The proposed methodology utilizes six accelerometers and three angular rate sensors (6aω con...

in this paper, the mean value of strain energy density criterion has been used to predict the critical fracture load in specimens with u-shaped notch under bending loads. an equation for calculation of averaged strain energy density in this zone has been presented. bending loads under mode i have been considered. two cases have been studied: 1) the control volume only includes the semicircular ...

BACKGROUND Longitudinal meniscus tears are commonly encountered in clinical practice. Meniscus repair devices have been previously tested and presented; however, prior studies have not evaluated repair construct designs head to head. This study compared a new-generation meniscus repair device, SpeedCinch, with a similar established device, Fast-Fix 360, and a parallel repair construct to a cros...

During operation in transit, rails are exposed to the combined effects of various loads (power, temperature, atmospheric), under influence which complex and usually interrelated processes occur rail metal: plastic deformation metal, development types irregularities on surface rolling head. The occurrence injuries their development, internal defects contact fatigue origin. All this leads signifi...

Pumped Hydropower Storage (PHS) is the maturest and most economically viable technology for storing energy regulating electrical grid on a large scale. Due to growing amount of intermittent renewable sources, necessity maintaining stability increases. Most PHS facilities today require geographical topology with differences in elevation. The ALPHEUS H2020 EU project has aim develop flat topologi...

1.Introduction Following several methods of some past publications, among these we refined an important idea that related queries could be derived from queries submitted within the same session. As the browsers not just provide the previous queries but more informations,so we could use these informations to build a expert database for a special user, base on the database ,we could analysis some...

This paper presents an insole FSR (Force Sensing Resistor) to dynamically detect weight variations in an exoskeleton system. The proposed methodology is intended for tasks of lifting and lowering heavy weights with an industrial exoskeleton to substantially reduce spinal loads during these manual handling activities. Instead of extensively placing high-dense force sensors by covering the whole ...
