The objective of this paper is to solve the equation of motion of semilunar heart valve vibrations. The vibration of the closed semilunar valves are modeled by a Caputo ...

An open web-based tool for automatic discovery in elementary Euclidean geometry, webDiscovery, is described. It is based in recent findings in automatic discovery in ...

With the help of Mathematica, many travelling for a class of nonlinear evolution equations u (subscript)u + au(subscript)xx + bu + cu^2 + du^3 = 0 are obtained by using ...

Strategies for reducing the effect of cumulative rounding errors in geometric numerical integration are outlined. The focus is, in particular, on the solution of separable ...

Curvilinear-axis Gaussian electron optical properties and aberration characteristics of wide electron beams for combined immersion magnetic-electrostatic lenses are studied. ...

A 1m thick slab is initially at 100°C. The front face temperature is fixed at 0°C. The back surface of the slab is insulated. We use the Schmidt numerical method to find ...

The flow of the Riemann zeta function, _ s = (s), is considered, and phase portraits are presented. Attention is given to the characterization of the flow lines in the ...

This volume provides the basic theory and principles behind imaging the subsurface of the Earth using reflection and refraction seismology, how to improve these images via ...

Many fascinating facts are known relating the roots of a polynomial to the roots of its derivatives. And whereas many of these facts are easily accessible to an undergraduate ...

We calculate stationary configurations of superposed states "soliton + cnoidal wave lattice" of the vector nonlinear Schrödinger equation, using the Darboux transformation ...
