In the following equations, p, v, ρ, t, c, and u are the acoustic pressure (the local deviation from the ambient pressure), velocity, density, time, the speed of sound, and the vector field particle velocity r
where ψ is the electrical potential, F is the Faraday constant, R is the universal gas constant, T is temperature, v is the average velocity of convective solvent flow, and Ci, x, zi and Di are, respectively, the concentration, position in the membrane, valence of charge and diffusion ...

Results show that the GP can predict the solution of the seismic wave equation with a lower level of error, while our developed neural network is more accurate for velocity (P- and S-wave) and density inversion. Keywords: Gaussian process (GP), Physics informed machine learning (PIML) ,...
aThe velocity used in the force equation is evaluated at each integration step by linear interpolation within the appropriate segment. 用于力量等式的速度在适当的段之内被评估在每综合化步由线性插值法。 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译 葡萄牙...
Its roots and main applications are in Statistical Mechanics, but many other domains benefit from its versatility to model various phenomena, where a probability density function (PDF) of the velocity of a particle evolves in time under the action of both deterministic and random fields of force....
If an object moves through a fluid, it experiences a resisting force, the drag force. The value of this force depends on the size and shape of an object, the density of the fluid, and the relative velocity of the object and the fluid. The equation is: Fd = 1/2 ×ρ× u² × ...
in which f represents external force per unit volume. In the derivation of the homogeneous, linearized, wave equation in Chapter 3, the linearized equation of conservation of mass was differentiated with respect to time and the linearized equations of conservation of momentum were differentiated with...
That is, the force acts in a direction opposite to the spatial change of potential, similar to an induced current in a coil producing a magnetic field to counter the temporal change of the magnetic field linking the coil. This is an act of conservation of energy; without the minus sign, ...
Equation of motion, mathematical formula that describes the position, velocity, or acceleration of a body relative to a given frame of reference. Newton’s second law, which states that the force F is equal to the mass m times the acceleration a, is the
