An equation for the characteristic curves of photographic plates used in astronomical work is presented along with the procedure used to fit the experimental data to the equation. Its accuracy in calculating line intensities is discussed. (Author)Krueger, T. K...
In this paper, we extend to the non-convex case the affine invariant geometric heat equation studied by Sapiro and Tannenbaum for convex plane curves. We prove that a smooth embedded plane curve will converge to a point when evolving according to this flow. This result extends the analogy betw...
For δ,∊ combinations that fall in the grey areas, the solutions of the Mathieu equation are stable. The δ,∊ points in white regions and on the boundary curves correspond to unstable solutions. The diagram is symmetric about the δ axis; for our purposes it is sufficient to show ...
The exponential of a complex number, ea+ib, can be defined by using Taylor series (1086). So, applying the property ex+y=exey, then this means that ea+ib=eaeib. Therefore, if we can compute eib, we can find the complex root. For this, the Euler's method is used (Euler method,...
The current research presents a novel technique for numerically solving the one-dimensional advection-diffusion equation. This approach utilizes subdivision scheme based collocation method to interpolate the space dimension along with the finite differen
Second, [Math Processing Error] should be designed such that it essentially compensates the linear order error term (15). The main idea for the latter is to adapt [Math Processing Error] through [Math Processing Error] to the different location of the interface of the varifold solution. Of ...

The surface charge and the sublayers of compact and diffuse counterions (ions of opposite charge to the surface charge) constitute what is commonly called the double layer. In 1924, Stern made corrections to the theory accounting for the layer of counterions nearest the surface. When ...
Thus, the form of the macroscopic system of equations can now be studied in terms of the properties of these tensors. In this subsection, we begin by describing the general form of the anisotropic system of equations, which serves as a generalization for both the isotropic and subsequent ...
