Sentence examples for evolution of a quantity from inspiring English sources

A projection is a potential future evolution of a quantity or set of quantities, often computed with the aid of a model.

The latter describes the evolution of a quantity, obtained by the difference of the two solutions, corresponding to coherent and mixed mode transport.

This allows us to calculate exactly the complete time evolution of any quantity as well as their mean values averaged over an infinite time.

The difference between the classical and quantum evolution of a given physical quantity goes to zero corresponding to ϵ 2, as evaluated by an inference, known in the mathematical literature as Egorov's theorem  [26,27].

The differential equations describing the time evolution of the quantity Q i of a substance in liver, fat, and poorly perfused or well perfused tissues were of the form where F i is blood flow through tissue i (i – 1,..., 4), V i is its volume, P i is the corresponding tissue/blood partition coefficient, and Cart is the arterial blood concentration.

High-resolution spectra are chracterized by the energy of the peak of nu Fnu, and the evolution of this quantity is examined relative to the emission intensity.

A quantity is called a "conserved quantity" when its amount is constant during the temporal evolution of a system.

Thus we obtain a reduced description for the evolution of a pattern boundary solely in terms of quantities on the boundary itself.

Accurate estimation of Ne relies on an idealized model that closely mimics the evolution of the calibration quantity in the natural population [7].

The main contribution of this work is a detailed experimental investigation of the evolution of turbulent quantities relevant to noise production, performed in the close vicinity of the airfoil leading edge subjected to grid turbulence, by means of stereoscopic Particle Image Velocimetry measurements.
