RISInterpolating Three-Dimensional Kinematic Data Using Quaternion Splines and Hermite Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Kinematic interpolation is an important tool in biomechanics. The purpose of this work is to describe a method for interpolating three-dimensional kinematic data, minimizing error while maintaining ...
An Algorithm for Estimating Acceleration Magnitude and Impact Location Using Multiple Nonorthogonal Single-Axis Accelerometers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accelerations of the head are the likely cause of concussion injury, but identifying the specific etiology of concussion has been difficult due to the lack of a valid animal or computer model. ...
Gender Differences in Capitate Kinematics are Eliminated After Accounting for Variation in Carpal Size
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous studies have found gender differences in carpal kinematics, and there are discrepancies in the literature on the location of the flexion∕extension and radio-ulnar deviation rotation axes ...
Static and Dynamic Error of a Biplanar Videoradiography System Using Marker-Based and Markerless Tracking Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of biplanar videoradiography technology has become increasingly popular for evaluating joint function in vivo. Two fundamentally different methods are currently employed to reconstruct 3D ...
An Investigation of the NOCSAE Linear Impactor Test Method Based on In Vivo Measures of Head Impact Acceleration in American Football
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance characteristics of football helmets are currently evaluated by simulating head impacts in the laboratory using a linear drop test method. To encourage development of helmets ...
