In many applications, such as structural testing or vehicle collision studies, rotational data are required. Modal analysis will mainly use it to identify rotational degrees of freedom (DOFs), where crash testing will mainly look into rotational inertia. Measuring rotational acceleration can be done by computing measurements from linear sensors, but this leads inevitably to an increase in measu...

In this project, we propose to develop a tracking based traffic performance measurement system for roundabouts and intersections. There are two main goals for the project. One is to be able to collect all types of traffic performance measurements by tracking each individual vehicle and to improve performance measurement accuracy. The other goal is to focus on roundabouts and intersections as tr...

Today human gait analysis systems are mainly laboratory optics based systems. Sometimes these devices could restric patients’ natural movements because of their construction and/or weight. Therefore [1, 2, 5] measurement results may be completed by some errors. Secondly, there are no fully-compact systems commercially available , which could provide mesurement of selected gait parameters heving...

Non-destructive measurement of acceleration-induced displacement fields within a closed object is a fundamental challenge. Inferences of how the brain deforms following skull impact have thus relied largely on indirect estimates and course-resolution cadaver studies. We developed a magnetic resonance technique to quantitatively identify the modes of displacement of an accelerating soft object r...

A controller using acceleration feedback has been applied to a flexible robot for which the position and velocity of the load are not measured. It is shown by using the Causal Ordering Graph (COG), that the motor can be controlled by using acceleration feedback and that it allows an exact tracking of the motor position, irrespective of the non-linear flexibilities of the axis and of the measure...
