In this paper the effects of rigid triangular passive vortex generators on a  hydrofoil were investigated numerically.  In the first step using the Finite Volume Method the bare hydrofoil  were modeled and the results of lift and drag coefficients were validated using experimental data. In the next step the hydrofoil armed with vortex generators was modeled and its effect on the hydrofoil perfo...

This study after reviewing  construction methods of generators in Archimedean copulas (AC),  proposes several useful lemmas related with generators of AC. Then a new trigonometric Archimedean family will be shown which is based on cotangent function. The generated new family is able to model the low dependence structures.

More than a billion people around the world have no access to electricity and about 85% of them residing in rural areas sub-Saharan Africa. The supply Nigeria right now is atrocious, dependence hospitals on on-grid unadvisable, hence need for suitable alternative. Solar cell refrigerators vaccine storage are offered as viable solution replace noisy eco-unfriendly gasoline diesel generators that...

We characterize infinitesimal generators of semigroups of holomorphic selfmaps of strongly convex domains using the pluricomplex Green function and the pluricomplex Poisson kernel. Moreover, we study boundary regular fixed points of semigroups. Among other things, we characterize boundary regular fixed points both in terms of the boundary behavior of infinitesimal generators and in terms of plu...
