93Hagen-Poiseuille flow from the Navier-Stokes equations — The flow of fluid through a pipe of uniform (circular) cross section is known as Hagen Poiseuille flow. The Hagen Poiseuille flow is an exact solution of the Navier Stokes equations in fluid mechanics. The equations governing the Hagen Poiseuille …

96Spin tensor — In mathematics and mathematical physics, the Euclidean group :SE(d) of direct isometries is generated by translations and rotations. Its Lie algebra is written:mathfrak{se}(d). Noether currentsThe Noether currents for the translations make up the …
97Oblique shock — A small scale X 15 placed in a NASA supersonic wind tunnel produces an oblique shock wave at the nose of the model (along with other shocks). An oblique shock wave, unlike a normal shock, is inclined with respect to the incident upstream flow… …
98Kuramoto model — The Kuramoto model, first proposed by Yoshiki Kuramoto (蔵本 由紀 Kuramoto Yoshiki ), is a mathematical model used to describe synchronization. More specifically, it is a model for the behavior of a large set of coupled oscillators. Its formulation… …
99Aortic valve area calculation — is an indirect method of determining the area of the aortic valve. The calculated aortic valve orifice area is currently one of the measures for evaluating the severity of aortic stenosis. A valve area of less than 0.8 cm² is considered to be… …
