For comparison, peak human aortic velocity is on the order of 1.0 1.7 m/second (DeMaria and Blanchard, 2007), which corresponds to ∼1 body length per second.
As a point of reference, human mucus velocity has previously been measured to be 40 μm/s in the main bronchi and 92 μm/s in the trachea in healthy subjects [ 41].
In the experimental study, despite of the continuous oscillation during the walking, the parameters estimation was precise and unbiased, showing also repeatability with human linear velocities changes.
For comparison, human blood velocities at the mitral and tricuspid valves are in the order of 0.6 1.3 m/second and 0.3 0.7 m/second, respectively (DeMaria and Blanchard, 2007), both of which are less than one body length per second (adult human body length is ∼1.7 m) (Kuczmarski et al., 2000).
Two higher velocity human subject tests using the Volvo Whiplash Injury Protection System (WHIPS) seat were also conducted.
In the social force model at each time step, their motion is described by the superposition of 2 types of force: With an internal motivation to the goal, a human adapts his/her velocity v to an intended direction by.
In human medicine, maximal velocity and pressure half-time of the regurgitant blood flow can be related to the severity of its consequences such as ventricular volume overload.
For both tasks (implicit, explicit) and for both stimuli (dot, human), the actual velocities were linearly related to the stimuli velocities.
We exploited this sensitivity to perform tissue Doppler-imaging-based heart wall velocimetry (Fig. 3), in analogy with clinical, ultrasound-based tissue Doppler imaging of human heart wall velocities (Ho and Solomon, 2006; Marcucci et al., 2008).
In humans, the peak velocity of an eye saccade is determined by the size of the actual eye movement rather than the size of target movement and is thus a ballistic movement generated without the need of sensory feedback during its execution (Bahill and Stark, 1979).
