We present an approximate solution of the Percus-Yevick integral equation for a binary mixture of hard spheres with non-additive diameters. Defining Rij the distance of closest approach between particles of species i and j by R12 = (R11 + R22) + ±, we obtain a closed set of equations ...
Thus, the Stern model considers that the distance of closest approach of a counterion to the charged surface is limited by the size of the ion. With this model, the addition of electrolyte results in not only a compression of the diffuse part of the double layer but also in a shift of ...
It is defined here using level set theory [63] equipped with a signed distance function – such as the Euclidean metric – to implicitly capture the domain’s geometry. For a given element, \(\Omega ^n\), of arbitrary type, three situations can occur depending on the level set sign at...
Every set contains distance, time passing on Earth and in the spaceship (only relativity approach), expected maximum velocity and corresponding kinetic energy (on the additional parameters section), and the required fuel mass (see Intergalactic travel — fuel problem section for more information). ...
A soap film stretched between two rings of unit radius centered at ±x0 will have its closest approach to the x-axis at x=0, with the distance from the axis given by c1, with x0 and c1 related by Eq. (22.26) or Eq. (22.29). (a) Show that dc1∕dx0 becomes infinite when x0...
The model-implied simulation-based power estimation (MSPE) approach is a new general method for power estimation (Irmer et al.,2024). MSPE was developed especially for power estimation of non-linear structural equation models (SEM), but it also can be applied to linear SEM and manifest models...

For example, in the solution of the equation of state, the positive real root is the one of interest. In any case, the physical constraints of the problem may dictate the feasible region of search where only a subset of the total number of roots may be indicated. Also, the physical ...
Details of discretization procedures related to the control-volume approach can be found elsewhere (see, for example, Patankar and Spalding, 1972) and shall not be repeated here. The final discretized equation takes the following form for a general nodal point P: (10.11)apφp=∑n=1Nanφn+b...
Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. As a plane curve, it may be defined as the path of a point moving so that its distance from a fixed line is equal
