Hudsonlhudson@swin.edu.auThis research investigates the potential usefulness of the transmuted<br />modified Weibull distribution for modelling lifetime data. We<br />attain the diagnostic shapes of the density and hazard functions. We<br />formulate the expressions for the moments,incomplete moments, Renyi<br />entropy and q- entropy. We estimate the mean, variance, coefficient<br />of variation, coefficient of skewness and coefficient of kurtosis based<br />on moment approach. The method of maximum likelihood is used for<br />estimating the model parameters. We illustrate the use of transmuted<br />modified Weibull distribution with an application to survival data.2018-04-27T20:04:11+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://www.ejpam.com/index.php/ejpam/article/view/3209The Proofs of Product Inequalities in Vector Spaces2018-04-27T20:04:11+00:00Benedict Barnesewiekwamina@gmail.comE.D.J. Owusu-Ansahdgraftt@gmail.comS.K. Amponsahewiekwamina@gmail.comC. Sebilewiekwamina@gmail.comIn this paper, we introduce the proofs of product inequalities:<br />u v ≤ u + v , for all u, v ∈ [0, 2], and u + v ≤ u v , for all<br />u, v ∈ [2, ∞). The first product inequality u v ≤ u + v holds for<br />any two vectors in the interval [0, 1] in Holder’s space and also valid any<br />two vectors in the interval [1, 2] in the Euclidean space. On the other<br />hand, the second product inequality u + v ≤ u v ∀u, v ∈ [2, ∞)<br />only in Euclidean space. By applying the first product inequality to the<br />L p spaces, we observed that if f : Ω → [0, 1], and g : Ω → R, then<br />f p g p ≤ f p + g p . Also, if f, g : Ω → R, then f p + g p ≤<br />f p g p .<br /><br />2018-04-27T20:04:11+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://www.ejpam.com/index.php/ejpam/article/view/3223On the Elementary Solution for the Partial Differential Operator $\circledcirc_c^{k}$ Related to the Wave Equation2018-04-27T20:04:11+00:00Sudprathai Bupasirisudprathai@gmail.com<p>In this article, we defined the operator $\diamondsuit _{m,c}^{k}$ which is iterated $k$-times and is defined by<br />$$\diamondsuit _{m,c}^{k}=\left[\left(\frac{1}{c^2}\sum_{i=1}^{p}\frac{\partial ^{2}}{\partial x_{i}^{2}} +\frac{m^{2}}{2}\right)^{2} - \left(\sum_{j=p+1}^{p+q}\frac{\partial ^{2}}{\partial x_{j}^{2}} - \frac{m^{2}}{2}\right)^{2}\right]^{k},$$<br />where $m$ is a nonnegative real number, $c$ is a positive real number and $p+q=n$ is the dimension of the $n$-dimensional Euclidean space $\mathbb{R}^{n}$, $x=(x_{1},\ldots x_{n})\in\mathbb{R}^{n}$ <br />and $k$ is a nonnegative integer.

There is numerous research about secret sharing schemes. However there is little research on secret sharing schemes based on extension fields. In this paper, we study secret sharing schemes based on extension fields over finite fields. We use two methods to recover the secret. We define the access structure and the accessibility degree for these secret sharing schemes. We also describe our theorems, definitions and a corollary2018-04-27T20:04:11+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://www.ejpam.com/index.php/ejpam/article/view/3246Subalgebras and Ideals in BCK/BCI-algebras Based on Uni-hesitant Fuzzy Set Theory2018-04-27T20:04:11+00:00G.

Characterizations of uni-hesitant fuzzy algebras and uni-hesitant fuzzy (closed) ideals are considered, and a new uni-hesitant fuzzy algebra (resp. uni-hesitant fuzzy (closed) ideal) from old one is established. Relations between uni-hesitant fuzzy algebras and uni-hesitant fuzzy (closed) ideals are discussed, and conditions for a uni-hesitant fuzzy ideal to be hesitant closed are provided.</p>2018-04-27T20:04:11+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://www.ejpam.com/index.php/ejpam/article/view/3229On M-Principally Injective and Projective S-acts2018-04-27T20:04:11+00:00Javed Hussainjaved.brohi@iba-suk.edu.pkMuhammad Shabirjaved.brohi@iba-suk.edu.pkIn this paper, we have introduced the notions of M-cyclic S-acts,<br />M-principally projective and injective S-acts, semi-projective S-acts and co-<br />cyclic S-acts, whereMis a right S-act.

The opposite is also true that when special conditions occur. The aim of this paper is to prove several theorems on Lie algebras with $BCL$ algebras. I introduce the notion of a "pseudo-association'' which I propose as the adjoint notion of $BCL$ algebra in the abelian group.2018-04-27T20:04:12+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://www.ejpam.com/index.php/ejpam/article/view/3193Almost Prime Ideal in Gamma Near Ring2018-04-27T20:04:12+00:00Waheed Ahmad Khanganitaouti@yahoo.com.auAdnan Muhammadganitaouti@yahoo.com.auAbdelghani Taoutiganitaouti@yahoo.com.auJameel Makiganitaouti@yahoo.com.au<p>In this manuscript we introduce the notion of almost prime ideals in -near-rings along with few of their characterizations.

It is important that a secret key, passwords, information of the map of a secret place or an important formula must be kept<br />secret. The main problem is to divide the secret into pieces instead of storing the whole for a secret sharing. A secret sharing scheme is a way of distributing a secret among a nite set of people such that only some distinguished subsets of these subsets can recover the secret. The collection of these special subsets is called the access structure of the scheme.<br />In this paper, we propose a new approach to construct secret sharing schemes based on field extensions.</p>2018-04-27T20:04:12+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://www.ejpam.com/index.php/ejpam/article/view/3266On Semilattice Congruences on Hypersemigroups and on Ordered Hypersemigroups2018-04-27T20:04:12+00:00Niovi Kehayopulunkehayop@math.uoa.grWe prove that if $H$ is an hypersemigroup (resp. ordered hypersemigroup) and $\sigma$ is a semilattice congruence (resp. complete semilattice congruence) on $H$, then there exists a family $\cal A$ of proper prime ideals of $H$ such that $\sigma$ is the intersection of the semilattice congruences $\sigma_I$, $I\in\cal A$ ($\sigma_I$ is the known relation defined by $a\sigma_I b$ $\Leftrightarrow$ $a,b\in I$ or $a,b\notin I$). Furthermore, we study the relation between the semilattices of an ordered semigroup and the ordered hypersemigroup derived by the hyperoperations $a\circ b=\{ab\}$ and $a\circ b:=\{t\in S \mid t\le ab\}$. We introduce the concept of a pseudocomplete semilattice congruence as a semilattice congruence $\sigma$ for which $\le\subseteq\sigma$ and we prove, among others, that if $(S,\cdot,\le)$ is an ordered semigroup, $(S,\circ,\le)$ the hypersemigroup defined by $t\in a\circ b$ if and only if $t\le ab$ and $\sigma$ is a pseudocomplete semilattice congruence on $(S,\cdot,\le)$, then it is a complete semilattice congruence on $(S,\circ,\le)$.

The proposed method is implemented to different models having system of partial differential equations (PDEs). The results obtained by proposed method are compared with Homotopy Analysis Method (HAM) and closed form solutions. The comparisons of these results show that MOHAM is simpler in applicability, effective, explicit, control the convergence through optimal constants, involve less computational work. The MOHAM is independent of the assumption of initial conditions and small parameters like Homotopy Perturbation Method (HPM), HAM, Variational Iteration Method (VIM), Adomian Decomposition Method (ADM) and Perturbation Method (PM). </p>2018-04-27T20:04:12+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematics
