The flow generated by a disc turbine in a cylindrical unbaffled tank was numerically modeled. This study was carried out for shear-thinning fluids. Analyses concern the effect of impeller rotational speed, fluid rheology and impeller blade curvature on the mean…

In this article we introduce the notion of p-absolutely summable class of sequences of fuzzy real numbers with fuzzy metric, $\ell_p^F, 1 \leq p < \infty$. We study some of its properties like completeness, symmetricity, solidness and convergence free. We…

In this paper, we introduce the relatively new notion of ζ-open subset which is strictly weaker than open. We prove that the collection of all ζ-open subsets of a space forms a topology that is finer than the original one.…

In this article we introduce the notion of weakly b–continuous functions in bitopological spaces as a generalization of b–continuous functions. We prove several properties of these functions.

In this paper we have introduced the notion of fuzzy real-valued p-bounded variation double sequence space 2bvp/F(1 ≤ p < ∞). We have studied some important properties like completeness, convergence free, solid, symmetric. Some inclusion results are also established.  ,

Temperature distribution which occurs in pavement and bridge slabs heated for de-icing and snow melting during cold periods is determined by using vertical ground-source heat pump (GSHP) systems with U-tube ground heat exchanger (GHE). The bridge and pavement models (slabs)…

In this paper, a new kind of set called an αγ-open set is introduced and investigated using the γ-operator due to Ogata. Such sets are used for studying new types of mappings, viz. αγ-continuous, α(γ,β)-irresolute, etc. Finally, new separation axioms:…

Higher homotopy of graphs has been defined in several articles. However, the existence of a long exact sequence associated to a pair (G, A) has not been touched at. We treat it here. Applied to the discrete spheres, this lead…

In this paper, we introduce the concept of αγ-open sets as a generalization of γ-open sets in a topological space (X, τ). Using this set, we introduce αγT0, αγ-T½, αγT1, αγT2, αγD0, αγD1 and αγD2 spaces and study some of…

In this paper, the concepts of (∈γ,∈γ vqδ)-fuzzy fantastic ideals and (¯∈γ, ¯∈γ v ¯qδ)-fuzzy fantastic ideals in BCH-algebras are introduced and investigate some of their properties.
