The study showed that chickenpox cases in recent times have increased in Agona West Municipality with R0=2. We estimated the reproductive number of chickenpox with vaccination to be R0=0.3<1. This showed that after vaccination, the disease will die out. It was estimated that 4...

In this paper we will study the main properties of the set solutions of the paratingent equation (type differential inclusion) with delay of the form: (Ptx)(t) ⊂ F([x]t) for t ≥ 0 with the initial condition: x(t) = ξ(t) for t ≤ 0. We will be interested particularly in the topolog...

In this paper, a novel auxiliary equation: φ′′ = a + bφ + cφ3 which has mutiple function solutions including trigonometric function, hyperbolic function and other functions, is considered. It is applied to a series of partial differential equations easily and effectively. It he...

In this paper, we introduce the concept of the harmonically P-functions, give Hermite-Hadamard’s inequalities for harmonically P-functions and define a new identity. By using this identity, we obtain new estimates on generalization of Hadamard and Simpson type inequalities for ha...

Aims: Classic Petri nets also known as place transition nets provide many interesting and useful features for system modeling. However they are limited by the place types that are used. An approach is presented where a matrix vector transition net is used for modeling complex sys...

Two parameter families of sixth-order iterative methods for finding simple zeros of nonlinear equations are developed. The new methods have the order of convergence order of five or six. Per iteration these new methods require two evaluations of the function and two evaluations o...

B. Alspach, C.C. Chen and Kevin Mc Avaney [1] have discussed the Hamiltonian laceability of the Brick product C(2n, m, r) for even cycles. In [2], the authors have shown that the (m, r)-Brick Product C(2n + 1, 1, 2) is Hamiltonian-t-laceable for 1 ≤ t ≤ diamn. In [3] the authors...
