coding theory, fuzzy finite state machines, and fuzzy languages. In this paper, we introduce the concept of an (􀟙, 􀟚)-fuzzy filter of an ordered semigroup 􀜵, where 􀟙, 􀟚 􀗐 􁈼􀗐, 􀝍, 􀗐􀗩 􀝍, 􀗐􀗨 􀝍􁈽 with 􀟙 􀵍􀗐􀗨 ...

In the present article, we focus on the numerical approximation of stochastic partial differential equations of Itˆo type with space-time white noise process, in particular, parabolic equations. For each case of additive ...

In this work we deal with the question: how can one improve the approximation level for some nonlinear integral equations? Good candidates for this aim are semi orthogonal B-spline scaling functions and their duals. ...

Biofacies and palaeoecology of the limestone of the Jahrum Formation in the Lar area in the southwest of Iran (Zagros Basin) is addressed in this paper. Our detailed analysis of biofacies and palaeoecology shows that ...

The treatment equimolar quantities of carboxylic acids with acid chlorides in the presence of ZnO brings abouthighly efficient unsymmetrical anhydrides at room temperature in solvent-free condition. Reactivity trendsfavored ...

In this paper, an effective direct method to determine the numerical solution of linear and nonlinear Fredholm and Volterra integral and integro-differential equations is proposed. The method is based on expanding the ...

Fennel (Foeniculum vulgare Mill.) is widely cultivated for its edible, strongly-flavored leaves, fruits, seeds andmedicinal uses. As the wild and cultivated plants are influenced by environmental stresses, the effects of ...

Highly active Cu (II) complex with 1,4-dihydroxy anthraquinone as a cheap and accessable ligand could be used as a catalyst for the preparation of structurally different propargylamines from a one-pot, three-component reaction ...
