Modeling, analyzing and simulating the dynamics of Lassa fever in Nigeria
- 2022
AbstractLassa fever is an infectious and zoonotic disease with incidence ranging
between a hundred to three hundred thousand cases, with approximately five
thousand deaths reported yearly in West Africa. This disease has become endemic
in the Lassa belt of Sub-Saharan Africa, thus increasing the health burden in
these regions including Nigeria. A deterministic mathematical model is presented
to st...
Some nano topological structures via ideals and graphs
Tập 28 Số 1 - 2020
AbstractIn this paper, new forms of nano continuous functions in terms of the
notion of nano Iα-open sets called nano Iα-continuous functions, strongly nano
Iα-continuous functions and nano Iα-irresolute functions will be introduced and
studied. We establish new types of nano Iα-open functions, nano Iα-closed
functions and nano Iα-homeomorphisms. A comparison between these types of
functions and o...
Bifurcation analysis of a composite cantilever beam via 1:3 internal resonance
- 2020
AbstractIn this paper, we study a multiple scales perturbation and numerical
solution for vibrations analysis and control of a system which simulates the
vibrations of a nonlinear composite beam model. System of second order
differential equations with nonlinearity due to quadratic and cubic terms,
excited by parametric and external excitations, are presented. The controller is
implemented to cont...
On the inverse sum indeg index of some graph operations
- 2020
AbstractTopological indices are the molecular descriptors that describe the
structures of chemical compounds. They are used in isomer discrimination,
structure-property relationship, and structure-activity relations. The
topological indices are used to predict certain physico-chemical properties such
as boiling point, enthalpy of vaporization, and stability. In this paper, the
inverse sum indeg in...
Casson rheological flow model in an inclined stenosed artery with non-Darcian porous medium and quadratic thermal convection
AbstractThe current study investigates the combined response of the
Darcy–Brinkman–Forchheimer and nonlinear thermal convection influence among
other fluid parameters on Casson rheology (blood) flow through an inclined
tapered stenosed artery with magnetic effect. Considering the remarkable
importance of mathematical models to the physical behavior of fluid flow in
human systems for scientific, bi...

Generalized mixed equilibrium problems and quasi- ϕ-asymptotically nonexpansive multivalued mappings in Banach spaces
Tập 27 - Trang 1-16 - 2019
In this paper, we introduce two iterative algorithms for finding a common
element of the set of fixed points of a quasi- ϕ-asymptotically nonexpansive
multivalued mapping and the sets of solutions of generalized mixed equilibrium
problem in Banach space. Then, we prove strong and weak convergence of the
sequences to element in the mentioned set. Our results generalize and improve
recent results an...
An integer-order SIS epidemic model having variable population and fear effect: comparing the stability with fractional order
Tập 30 Số 1
AbstractThis paper investigates the dynamics of an integer-order and
fractional-order SIS epidemic model with birth in both susceptible and infected
populations, constant recruitment, and the effect of fear levels due to
infectious diseases. The existence, uniqueness, non-negativity, and boundedness
of the solutions for both proposed models have been discussed. We have
established the existence of...
Properties of neighborhood for certain classes associated with complex order and m-q-p-valent functions with higher order
Tập 30 Số 1 - 2022
AbstractIn this paper, by using q-calculus (Jackson’s q-derivative) $$D_{q,p}$$
D q , p we defined new operator $$D_{\lambda ,q,p}^{n}f^{(m)}(z)$$ D λ , q , p n
f ( m ) ( z ) . After that, we used this operator to introduce two new
subclasses of multivalent analytic functions with complex order. Also, we
obtained coefficients estimates and consequent inclusion relationships involving
the $$N_{j,\d...
