Distraction (in most cases, text messaging) had a significantly negative impact on traffic flow, such that participants exhibited greater fluctuation in speed, changed lanes significantly fewer times, and took longer to complete the scenario.
The influence of wake variation, ship motions, RPM fluctuations and speed loss is studied.
Any fluctuations in speed should be uncorrelated with anything the driver can see.
The original was made on a 78 r.p.m. recording marred by fluctuations in speed and audible clicks and pops.
Instead of a consistent pulse, Mr. Eschenbach leaned toward fluctuations of speed that seemed to fluster rather than inspire the players.
Both pieces call on performers to mimic speech on their instruments with extended technique and constant fluctuations of speed and meter.
Here's a summary of their findings from a news release: The research found that tiny fluctuations in speed, always existing when drivers want to keep appropriate headway space, have a cumulative effect.
One has to absorb all of this - the tiniest fluctuations of speed, fingerings, bowings, colours - until it becomes completely natural, and then the music can come alive in a way that is not complex or studied to the listener, but, rather, fluid and improvised-sounding.
Single and double integration of acceleration from IMU provides information about short-term fluctuations in speed and position, but suffers from integration error over a longer period of time.
To exclude the possibility that the physiological differences between coactivation and non-coactivation bilateral trials were due simply to random fluctuations in speed, we compared BOLD response on the fastest and slowest 20% of unilateral trials.
