The Fornberg-Whitham Equation Solved by the Differential Transform Method

Helena Nayar & Patrick Azere Phiri · Journal of Advances in Mathematics and Computer Science · 2020

The Differential Transform Method is a powerful analytical method that can solve nonlinear partial differential equations. Yet, the method cannot be used to solve time-dependent partial differential equations that involve more than one partial derivative with respect to the tempo...

Meta-Heuristic Solutions to a Student Grouping Optimization Problem faced in Higher Education Institutions

Kenekayoro Patrick & Biralatei Fawei · Journal of Advances in Mathematics and Computer Science · 2020

Combinatorial problems which have been proven to be NP-hard are faced in Higher Education Institutions and researches have extensively investigated some of the well-known combinatorial problems such as the timetabling and student project allocation problems. However, NP-hard prob...

Solution of Two-Point Linear and Nonlinear Boundary Value Problems with Neumann Boundary Conditions Using a New Modified Adomian Decomposition Method

Justina Mulenga & Patrick Azere Phiri · Journal of Advances in Mathematics and Computer Science · 2020

In this paper, we present the New Modified Adomian Decomposition Method which is a modification of the Modified Adomian Decomposition Method. The new method incorporates the inverse linear operator theorem into the modified Adomian decomposition method for the calculation of u0....

A Mathematical Modeling of Tuberculosis Dynamics with Hygiene Consciousness as a Control Strategy

Phineas Z. Mawira & David M. Malonza · Journal of Advances in Mathematics and Computer Science · 2020

Tuberculosis, an airborne infectious disease, remains a major threat to public health in Kenya. In this study, we derived a system of non-linear ordinary differential equations from the SLICR mathematical model of TB to study the effects of hygiene consciousness as a control stra...

Simulation of a Deterministic Model of HIV Transmission between Two Closed Patches

James Khobocha Mirgichan, Cyrus Gitonga Ngari & Stephen Karanja · Journal of Advances in Mathematics and Computer Science · 2020

Numerical simulation of a deterministic model of HIV transmission between major cities in Kenya is carried out. The model considered two closed patches connected by the commuter movements of truck drivers being the agents of HIV transmission. The transmission kernel being the fun...

A Theoretical Model of Corruption Using Modified Lotka Volterra Model: A Perspective of Interactions between Staff and Students

Mercy Kawira, Cyrus Gitonga Ngari & Stephen Karanja · Journal of Advances in Mathematics and Computer Science · 2020

Corruption is the misuse of power or resources for private gain. This undermines economic development, political stability, and government legitimacy, the society fabric, allocation of resources to sectors crucial for development, and encourages and perpetuates other illegal oppo...

On gω-Open Sets in Grill Topological Spaces

Amin Saif, Mohammed Al-Hawmi & Basheer Al-Refaei · Journal of Advances in Mathematics and Computer Science · 2020

The propose of this paper is to introduce and investigate a weak form of ω-open set in grill topological spaces. We introduce the notion of -open set as a form stronger than βω-open set and weaker than ω-open set and -open set. By using this form, we study the generalization prop...

Some Topological and Algebraic Features of Symmetric Spaces

Um Salama, Ahmed Abd Alla & A. Elemam · Journal of Advances in Mathematics and Computer Science · 2020

In this study, we introduce some approaches, geometrical and algebraic, which help to give further understanding of symmetric spaces. Symmetric space is a very important field for understanding abstract and applied features of spaces. We have introduced Riemannian Manifold, Lie g...

The Reciprocal Generalized Inverse Gaussian Frailty with Application in Life Annuity Business

Walter Onchere, Richard Tinega, Patrick Weke & Jam Otieno · Journal of Advances in Mathematics and Computer Science · 2020

Aims: As shown in literature, several authors have adopted various individual frailty mixing distributions as a way of dealing with possible heterogeneity due to unobserved covariates in a group of insurers. This research contribution is to generalize the frailty mixing distribut...

Regional Boundary Exact Controllability of the Wave Equation by Strategic Actuators on a Polygonal Domain with Cracks

Cheikh Seck, Ousmane Sène & Teuw Niane · Journal of Advances in Mathematics and Computer Science · 2020

In this work we prove the exact controllability of the wave equation by acting on a strategic zone of the border of a non-convex polygonal domain with crack. Indeed, by combining two methods: that of Grisvard on the exact controllability on domains with corners and that of EL. Ja...
