The pricing of seasonal and perishable crops such as tomatoes is of paramount concern to emerging economies. In this paper, we have formulated a model for the prices of tomatoes in the Ashanti Region of Ghana. We applied time series on the tomatoes price data recorded over the pe...

In this paper, we investigate the global stability and the existence of traveling waves for a delayed diffusive epidemic model. The disease transmission process is modeled by a specific nonlinear function that covers many common types of incidence rates. In addition, the global s...

Let N denote the set of non-negative integers. A set of non-negative, n-dimensional integral vectors, M⊂Nn, is said to be right-closed, if ((x ∈ M) ∧ (y ≥ x) ∧ (y ∈Nn)) ⇒ (y ∈ M). In this paper, we present a polynomial time algorithm for testing the convexity of a right-closed se...

In this paper, we study strong and weak convergence results of a two step iterative process with errors for a pair of asymptotically non-expansive mapping in the intermediate sense.Our results generalize the corresponding results due to Hou and Du [4] by taking the class of asymp...

A double-threshold system (DTS) is a system that is successful if and only if the weighted arithmetic sum of its successes/failures equals or exceeds a certain threshold T1 and is smaller than or equal to a certain threshold T2. Generally a DTS is neither symmetric nor coherent....
