Both these scans were performed with more time for one rotation compared to the third, dynamic scan described next, so they could be reconstructed with a higher signal-to-noise ratio. Finally, a fast dynamic scan was taken of the rock, starting from the situation where the pores were filled...
Now that we have the angular velocityw, the next step is to calculate the time derivative of the rigid body orientation with angular velocityw. There are two ways to store orientation: using a rotation matrix or using a quaternion. We choose to use a quaternion, which is ...
Added option to gradually correct small time errors instead of adjusting the time in one hit - thanks to code provided by Julien Blitte Added log file rotation - also thanks to Julien Blitte. Fixed a problem with high CPU usage when a lot of logging activity taking place. ...
The breakdown of time-reversal symmetry and the departure from the Boltzmann distribution are responsible for a rich phenomenology in active systems, with no counterparts in equilibrium. In the presence of obstacles or external potentials, the departure from the Boltzmann distribution is reflected by a...
UTC signifies Coordinated Universal Time. Think of this as the true time on planet Earth thatneverchanges (except for minor leap seconds here and there to account for changes in the planet's rotation). For more information about UTC, seeCoordinated Universal Time. ...
Time has been measured by the planet’s rotation for thousands of years; however, it was not until 1949 that scientists developed a clock that kept perfect time. The IERS atomic clock keeps time by measuring the vibrations of atoms. As far as scientists know, the cesium atom—which vibrate...
This historical decision is why GMT is still occasionally used as a substitute for UTC today. At the time, GMT wasbased on Earth’s rotation—specifically, on the mean solar time at theprime meridian, which runs through the Royal Observatory in Greenwich,London. ...
uptime- a period of time when something (as a machine or factory) is functioning and available for use work time- a time period when you are required to work time off- a time period when you are not required to work; "he requested time off to attend his grandmother's funeral" ...
rotation - The rotation angle in degrees between0 and 360. camera - A Camera object that defines the observer for the scene. Viewpoint::Viewpoint(const Esri::ArcGISRuntime::Point ¢er, double scale, double rotation) A constructor that creates a Viewpoint with center point, scale, and ro...
However, simply selecting one of the two faces generally gives acceptable results.Finally, it is important to realize that when very large time steps are used, quantities can "leak" through boundaries during advection. For this reason we add an additional constraint to the...
