A right A-module M is a -module provided that M is self-small and any exact sequence 0 → N → L → Q → 0, with L, Q ∈ Stat(M) remains exact after applying the functor HomA(M, -) if and only if N ∈ Stat(M). A right A-module M is called a -module if it is self-small, (n + 1)-quasi-...

A large eddy simulation (LES) of a turbulent channel flow is performed by using the Smagorinsky subgrid scale model and the effects of Smagorinsky constants in LES are discussed. The computation is performed in the domain of 2πδ x 2δ x πδ with 32 x 64 x 32 grid points at a Reynol...

In paper [1] Ahmad et al. investigated the use of sharp function, known from functional analysis, in image processing. The sharp function gives a measure of variations of a function and can be used as an edge detector [2]. We extend the classical notion of sharp function to prove...
