Replacing ṽ′(x0,τ) by J̇(x0,τ) because of (9) we can write the last equation as ∂τln(ñJ)=0 and get for the Lagrangian density by integration (13)ñ(x0,τ)=n0(x0)J(x0,τ), where n0(x0) is a constant with respect to τ, representing the initial dens...

A boundary integral equation representation for the non-constant-α force-free field in space outside the Sun was investigated by Yan & Sakurai, who introduced a local parameter λ instead of the force-free factor α which should satisfy a proposed condition. Then the field at any point in ...
ρg is the gravitational force on the element per unit volume, kg/m2/s2; g is the acceleration of gravity (9.807 m/s2); [∇ τ] can be revised in terms of the fluid viscosityμ, assuming constant μ and constant ρ. (2.4)[∇·τ]=μ∇2υ For the case of constant μ and ...

(General Physics) an equation used in wave mechanics to describe a physical system. For a particle of massmand potential energyVit is written (ih/2π).(∂ψ/∂t) = (–h2/8π2m)∇2ψ + Vψ, where i = √–1,his the Planck constant,tthe time, ∇2the Laplace operator, and...
1.An expression of Newton's second law that relates forces, displacements, and their derivatives for a mechanical system. 2.For the respiratory system, an equation that relates the forces involved in breathing to the displacements they produce. Typically, pressure differences are used to represent ...
It is important to be aware that an assumption of the steady-state heat transfer cannot be used for modeling thermal processes of induction hardening because, according to the steady-state approach, the temperature would remain constant at a given point of heated component, for all time. However...
