On the right are trending stocks based on velocity of conversation.
Analysing the complex flow pattern in the aorta solely based on velocity information is difficult.
In experiment 1, they identified saccades based on a velocity threshold of 30°/s, and determined the start and end of a saccade as having a velocity of at least two standard deviations higher than the velocity of the previous fixation (see also van der Steen & Bruno, 1995).
In-house software allowed monitoring of eye movement data both for off-line analysis and for on-line change of the visual display synchronised to the primary saccade (detection of this saccade was based on a velocity threshold of 70−90°/sec).
We develop the handoff algorithm based on an optimal velocity threshold.
Initial fixations were defined as the fixation following the first fixation during onset of the image (based on an adaptive velocity threshold method; see Nyström & Holmqvist, 2010; Smeets & Hooge, 2003).
Saccades were detected automatically with an algorithm based on an initial velocity threshold of 30°/s, a saccade peak cutoff of 15% and a minimum duration of 30 ms. Additionally, visual inspection of each saccade was done to validate saccade onset and offset and to correct for possible errors of the algorithm.
Each informed bee uses its updated location estimate to compute an intermediate velocity vector based on a threshold computation.
A simple method based on safety threshold of vibration velocity for rock mass to restrict the damage depth of rock mass under blasting excavation is presented.
Detailed estimates of the uncertainty that propagates through the calculation based on the friction velocity thresholds (e.g. following Richardson and Hollinger 2007) was beyond the scope of this paper.
