Locking a block or an object is a time-consuming operation due to the nature of the underlying operating system-level operation involved (see concurrency control and lock granularity). As the Java library does not know which methods will be used by more than one thread, the standard library always locks blocks when needed in a multithreaded ...
Due to different speaking rates, a non-linear fluctuation occurs in speech pattern versus time axis, which needs to be eliminated. [31] DP matching is a pattern-matching algorithm based on dynamic programming (DP) , which uses a time-normalization effect, where the fluctuations in the time axis are modeled using a non-linear time-warping function.
The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; [2] the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of ...
The relative velocity of an object B relative to an observer A, denoted (also or ), is the velocity vector of B measured in the rest frame of A. The relative speed v B ∣ A = ‖ v B ∣ A ‖ {\displaystyle v_{B\mid A}=\|\mathbf {v} _{B\mid A}\|} is the vector norm of the relative velocity.
The radial speed or range rate is the temporal rate of the distance or range between the two points. It is a signed scalar quantity, formulated as the scalar projection of the relative velocity vector onto the LOS direction. Equivalently, radial speed equals the norm of the radial velocity, modulo the sign. [a]

The speed-dependence of the friction force is linear (()) at very low speeds (Stokes drag) and quadratic (()) at large speeds (Newton drag). [8] The transition between these behaviours is determined by the Reynolds number , which depends on object speed and size, density ρ {\textstyle \rho } and dynamic viscosity η {\textstyle \eta } of the ...
Travelling a greater distance in the same time means a greater speed, and so linear speed is greater on the outer edge of a rotating object than it is closer to the axis. This speed along a circular path is known as tangential speed because the direction of motion is tangent to the circumference of the circle.
