The two-electron problem for the helium-like atom/ions in S-state is considered. The basis containing the integer powers of lnr, where r is a radial variable of the Fock ...

This notebook considers the problem of an inviscid flow past a stationary sphere. Solutions are obtained using both a potential function and a stream function. The pressure ...

A class of doubly periodic waves for several nonlinear evolution equations is studied by the Hirota bilinear method. Analytically these waves can be expressed as rational ...

The influence of partial slip, thermal radiation, chemical reaction and temperature-dependent fluid properties on heat and mass transfer in hydro-magnetic micropolar fluid ...

In this study, the problem of geoid correction based on GPS ellipsoidal height measurements is solved via symbolic regression (SR). In this case, when the quality of the ...

A predictive marker is a baseline variable in a randomized trial that is used to determine subgroups in which the effect of treatment is greater than average. This software ...

The authors present a surprisingly efficient random number generator that applies in principle to any discrete univariate probability mass function without alteration.

The package extends the built-in function NDSolve to deal with delay differential equations.Updated package -- March 8, 2004

Version 2.0's new Module function permits true static scoping. Also: using pipes to enhance functional programming.

The use of rational approximants to simulate the natural boundary of a function is examined. Determination of the poles of the approximants illustrates the enormous power of ...
