In this paper we study a general family of skew-symmetric distributions which are generated by the cumulative distribution of the normal distribution. For some distributions, moments are computed which allows computing asymmetry and kurtosis coefficients. It is shown that the range for asymmetry ...

An integral approach is presented to strengthen the teaching and learning processes in the environment of the undergraduate course Numerical Analysis (NA) for engineering, examining tha advantages of combining the symbolic and numeric paradigms. In particular, the methodology is illustrated with ...

Ranging from Re=100 to Re=20,000, several computational experiments are conducted, Re being the Reynolds number. The primary vortex stays put, and the longterm dynamic behavior of the small vortices determines the nature of the solutions. For low Reynolds numbers, the solution is stationary; for ...

We study the univalence of fa,define as a integral of the power á of f', in terms of the values of á when f belongs to certain subclasses of univalent functions.

In this paper, we introduce a new class of skew-symmetric distributions which are formulated based on cumulative distributions of skew-symmetric densities. This new class is an extension of other skew-symmetric distributions that have already been studied. We give special attention to a family fr...

With in-depth refinement, the condition number of the incremental unknowns matrix associated to the Laplace operator is p(d)O(1/ H2)O( logd<sup/>h 3) for the first order incremental unknowns, and q(d)O(1/H2) O((logdh)2) for the second order incremental unknowns, where d is the depth of the refine...
