Project Evaluation and Review Technique (PERT) in conjunction with Monte Carlo simulation is no doubt a useful and an acceptable tool for the analysis of project networks. However, a common challenge in practice is the inability to confidently select appropriate input distributi...

In this paper, we establish the closedness and convexity of the fixed point set of asymptotically demicontractive mappings in the intermediate sense introduced by Olaleru and Okeke [Convergence theorems on asymptotically demicontractive and hemi-contractive mappings in the interm...

In this paper, the motion of a non-uniform elastic structure resting on exponentially decaying Vlasov foundation and under repeated rolling concentrated loads moving with constant velocity is analyzed. The governing equation is a fourth order partial differential equation. The so...

The effect of variable axial force on the deflection of thick beam under moving load is investigated in this research work. In order to obtain solution to the dynamic problem, a technique base on the method of Galerkin with the series representation of Heaviside function, was fir...

This study is focused on monotonicity and convexity properties of a generalized form of the Wallis’ cosine formula. Specifically, by using the integral form of the Nielsen’s β-function, we prove that the generalized Wallis’ cosine formula is logarithmically completely monotonic,...

In this article we consider identification of maximum safe dose (MSD) in a dose response study for distribution-free endpoints. Where the maximum safe dose is the highest dose level that does not exceed the median toxicity of the zero dose by a predetermined margin. A nonparametr...

We introduce and study a new continuous model so called, the length-biased weighted Erlang (LBWE) distribution. Some mathematical properties of the new distribution such as, raw and incomplete moments, generating functions, Rényi of entropy, order and record statistics are invest...

Fermat's Last Theorem states that there are no solutions to xn + yn = zn for n ≥ 3 and x; y; z non-zero integers. Fermat wrote down a proof for n = 4 [1]. In 1753, Lenohard Euler (1707{1783) wrote down a proof of FLT for the exponent n = 3 [1]. Since any integer n ≥ 3 is divisibl...

We study the strong consistency and asymptotic normality of the maximum likelihood estimator (MLE) of a drift parameter in a stochastic volatility model when both the asset price process and the stochastic volatility are driven by independent fractional Brownian motions. Long mem...

We introduce a “structure” of epic proportions – golden pyramid whose sacred geometry is “Fibonacci squared”. In terms of mathematical beauty, the golden pyramid will perhaps be found to be comparable to Pascal triangle.

Brahmagupta introduced zero into the genus of real numbers and discussed operations involving it. Of these the operation of division by zero has caused a lot of disputes among mathematicians. The ultimate aim of this work is to clarify and justify Bhaskara’s arithmetic operation...

The symmetric genus of a finite group G is defined as the smallest genus s of a compact connected oriented surface on which G acts faithfully via diffeomorphisms, which may be orientation-preserving or orientation-reserving. In this paper we determine a useful lower bound for the...
