Differentiation of computed sum of hourly and daily reference evapotranspiration in a semi-arid climate [PDF]

Journal of Applied Research in Water and Wastewater, 2017
Electronic weather stations have increased the availability of weather data for computing hourly and daily reference evapotranspiration (ETo). There is a rational question applied for different climate conditions whether the sum of hourly ETo computation

On The Direct Sum Of Min(Max) - CS Modules

Journal of Kufa for Mathematics and Computer, 2013
In this paper, we study the direct sum of min (max)-CS modules. We show that the direct sum of min (max)-CS modules need not be min (max)-CS module. So we give many sufficient conditions under which the direct sum of min (max)-CS modules become min (max)

Direct sum of Intuitionistic fuzzy quasi injective s-act

Academic Science Journal
In order to define the intuitionistic fuzzy s-act of the direct sum Ai ⨁ Aj, we first introduce the idea of the direct sum of intuitionistic fuzzy s-act (L = Li ⨁ Lj) of A and go over a few associated properties if Li and Lj are intuitionistic fuzzy s ...

A Hyperstructural Approach to Semisimplicity

Axioms
In this paper, we provide the basic properties of (semi)simple hypermodules. We show that if a hypermodule M is simple, then (End(M),·) is a group, where End(M) is the set of all normal endomorphisms of M. We prove that every simple hypermodule is normal

Order Ideals on Lexicographic Direct Sum of Three Totally Ordered Abelian Groups

Cauchy: Jurnal Matematika Murni dan Aplikasi
Order ideals play an important role in the study of abstract algebra, especially in the study of ordered groups. In this paper, we focus on the study of order ideals in lexicographic direct sums of totally ordered Abelian groups.

Semicomplete Leibniz Algebras

Mathematics
We study the notion of semicomplete Leibniz algebras and investigate their fundamental properties. In particular, we classify all non-Lie Leibniz algebras of dimension at most three according to their semicompleteness and establish structural results ...

CHARACTERIZATIONS OF INTUITIONISTIC FUZZY SUBSEMIRINGS OF SEMIRINGS AND THEIR HOMOMORPHISMS BY NORMS

Journal of New Theory, 2017
In this paper, we introduce the notion of intuitionistic fuzzy subsemirings, level subsets of of intuitionistic fuzzy subsemirings, intersection and direct sum of intuitionistic fuzzy subsemirings under norms and investigate many properties of them.

$G$-amenability for Direct Sum, Tensor Product and Free Product of von-Neumann Algebras [PDF]

ریاضی و جامعه
For a family of $W^*$-dynamical systems $(M_i, G, \alpha_i)_{i\in I}$, where $G$ is a locally compact group, we prove that if the direct sum $\bigoplus_{i \in I} M_i$ is $G$-amenable, then each $M_i$ is also $G$-amenable.Conversely, if all $M_i$'s form a

System of Non-Linear Volterra Integral Equations in a Direct-Sum of Hilbert Spaces

Journal of Nigerian Society of Physical Sciences, 2022
We use the contraction mapping theorem to present the existence and uniqueness of solutions in a short time to a system of non-linear Volterra integral equations in a certain type of direct-sum H[a; b] of a Hilbert space V[a; b].

Two-interval even order differential operators in direct sum spaces with inner product multiples

上海师范大学学报. 自然科学版, 2017
We study two-interval singular differential equations and show that their self-adjoint operator realizations in direct sum Hilbert spaces can be enlarged by using inner product multiples.
