Abstract: This work deals with the calculation of a class of Gaussian integral of the form where Completing the squares of the exponential and changing variables led to the solution where denotes the cumulative standard normal distribution function. An equation which corresponds to pay-off at expiry for European option was derived. Key words: Gaussian integral, Euler-Poisson integral, multivariabl... PubDate: Thu, 31 Mar 2022 00:00:00 +010
Abstract: In this paper, we propose a model for estimating population proportion of a personality possessing two related sensitive attributes in survey sampling by extending Warners Randomized Response Technique (RRT). The proposed estimators are more efficient than Lees simple model estimators as the population proportion escalates. Our proposed model performs better than Lees crossed model estimator...

Abstract: This paper represents a continuation of a previous study on Analysis of a Sliding Frictional Contact Problem with Unilateral Constraint. This study considers a mathematical model which describes the equilibrium of an elastic body in frictional contact with a moving foundation. The contact is modeled with a multivalued normal compliance condition with unilateral constraints, associated to a s... PubDate: Wed, 30 Jun 2021 00:00:00 +010
Abstract: In the current paper, the concept of one-dimensional Shehu Transform have been generalized into three-dimensional Shehu Transform namely, Triple Shehu Transform (TRHT). Further, some main properties, several theorems and properties related to the TRHT have been established. Triple Shehu transform was used in solving fractional partial differential equations, with the fractional derivative de... PubDate: Wed, 30 Jun 2021 00:00:00 +010
Abstract: A sunflower (or ∆-system) with k petals and a core Y is a collection of sets S1,⋯, Sk such that SiSj=Y for all ij; the sets S1\Y,⋯, Sk\ Y, are petals. In this paper, we first give a sufficient condition for the existence of a sunflower with 2 petals. Let F={A,B,C} be a family of subsets of a set { a1,⋯,am , b1,⋯,bn , c1,⋯,cn } with and A={a1,⋯,am}, B={ b1,⋯,bn } and C={ c1,⋯,cn } are non-inc... PubDate: Sun, 31 Jan 2021 00:00:00 +010
Abstract: Riemanns hypothesis, formulated in 1859, concerns the location of the zeros of Riemanns Zeta function. The history of the Riemann hypothesis is well known. In 1859, the German mathematician B. Riemann presented a paper to the Berlin Academy of Mathematic. In that paper, he proposed that this function, called Riemann-zeta function takes values 0 on the complex plane when s=0.5+it. This hypoth... PubDate: Mon, 30 Nov 2020 00:00:00 +010
Abstract: A two-parameter weighted Monsef distribution (WM) is proposed in this paper. WM is flexible and has the property that the hazard rate function can accommodate both increasing and bathtub shapes. Most of its mathematical properties, such as probability density function, hazard function, moments and mean residual life function, are derived. The maximum likelihood method is used to estimate the... PubDate: Mon, 31 Aug 2020 00:00:00 +010
Abstract: This paper is concerned with the solution of a class of fourth order initial value problems in ordinary differential equation by the integrated formulation of the Tau method. The initial focus is the class with a maximum of third degree overdetermination. The matrix equations were constructed based on the degree of overdetermination and for purpose of automation. The automated Tau system was... PubDate: Mon, 31 Aug 2020 00:00:00 +010
Abstract: Sanchez et al. (2005) have shown the structure of vector space genetic code over the Galois field GF(4) which relate to the physicochemical properties of the genetic code on proteins. From this vector space, an automorphism can be constructed to reflect the mutation process in the genetic code. This study investigates a type of transformation in the LK_ITB5a lipase gene mutation. The result ... PubDate: Fri, 31 Jul 2020 00:00:00 +010
Abstract: Mathematics is the science that deals with the logic of shape, quantity and arrangement, and mathematical sciences have become important aspects of everyday life. It underpins many fields that provide benefits for humanities including but not limited to Internet search, medical imaging, computer animation, numerical weather predictions, and all types of digital communications (Hu, 2016) PubDate: Sun, 31 May 2020 00:00:00 +010
