Powell-Sabin splines are C-continuous quadratic splines defined on an arbitrary triangulation. Their construction is based on a particular split of each triangle in the triangulation into six smaller triangles. In this article we give an overview of the properties of Powell-Sabin splines in the context of computer aided geometric design. These splines can be represented in a compact normalized ...

The effect toxic industrial discharge on the environment and ecosystem cannot be overlooked. This is owing to a partial combustion of hydrocarbon arising from activities human endeavours. As such, this investigation focuses pressure driven flow heat propagation combustible Prandtl-Eyring viscous heating fluid in horizontal device. combustion-reaction viscoplastic material considered inspired by...

A new theoretical model based on the local composition concept (TNRF-mNRTL model) was proposed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. This contribution of interaction along with the long-range contribution of interaction (Pitzer-Debye-Hückel equation), configurational entropy of mixing (Flory-Huggins relation)...

The analysis in view is proposed to investigate the impacts of entropy peristaltically flown Ree–Eyring fluid under stress a normally imposed uniform magnetic field non-uniform symmetric channel varying thickness. administering equations present flow problem are switched into non-dimensional form and then reduced by availing long wavelengths creeping regime restrictions. analytical treatment fo...

962142. 43 In this more recent work, McGinnis and Rappaport cite Powell to instruct us on the interpretive conventions of the founding generation. Id. at 8 (citing Powell, supra note 39). And Powell at least provides McGinnis and Rappaport some useful support when he announces: "Although the Philadelphia framers did not discuss in detail how they intended their end product to be interpreted, th...

We study spectral Galerkin approximations of an Allen–Cahn equation over the two-dimensional torus perturbed by weak space-time white noise of strength √ ε. We introduce a Wick renormalisation of the equation in order to have a system that is welldefined as the regularisation is removed. We show sharp upper and lower bounds on the transition times from a neighbourhood of the stable configuratio...
