In this paper, we introduce a new model called the Type II half logistic Rayleigh (TIIHLR) with U-shaped, increasing and decreasing hazard rate function. Some structural properties of the current distribution are derived including; explicit expressions for moments, incomplete mom...

A one-step five off-grid implicit hybrid block method for the solution of stiff Second Order Ordinary Differential Equations is developed. The continuous hybrid linear multistep method was generated using power series approximation via interpolation and collocation at the grid po...

In this paper, a fault discovery structure is presented to increase the protection and reliability of the Elliptic Curve Digital Signature Algorithm (ECDSA) under practical considerations. As the ECDSA will work in real systems, which have their own arrangement of transient error...

In this work, the special solutions of the Restricted Three-Body Problem (RTBP) are presented which specify the locations of the equilibrium points. The periodic orbits around these libration points are obtained analytically and numerically. The Lissajous orbits around the collin...

In this paper, a deterministic mathematical model incorporating interference is developed and analysed to investigate the role of interference on the transmission dynamics and management of HIV and AIDS. The model is shown to be positively invariant as well as bounded. The endemi...

We construct exponential objects in categories of generalized uniform hypergraphs and use embeddings induced by nerve-realization adjunctions to show why conventional categories of graphs and hypergraphs do not have exponential objects.

In this paper, we propose a SEIR-SEI epidemic model for malaria transmission which describes the interaction between human and mosquito population, with the effects of antibodies produced by the incidence rates for humans and mosquitoes respectively and two optimal controls. We i...
