Mathematical modeling of infectious disease and designing vaccination law for control of this diseases
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2014, Vol 9, Issue 5
Abstract
In this paper, we propose the concept of partial stability instead of that of global stability to deal with the stability issues of epidemic models. The partial stability is able to provide a more meaningful analysis of the problem since it only focuses on the behavior of some of the variables (infected and infectious) instead of the complete population. It has been shown that the vaccination free SEIR model can still be partially stable even when a globally stability property does not hold, for two types of nonlinear incidence rates. By introducing the concept of partial stability and by designing a control vaccination based on it. Guarantee the eradication of an epidemic disease without requiring the global stability of the epidemic model.

New Analytical and Empirical Expressions for the Percentage of the Star's Flux Through TransparentAtmosphere Between Two Wave Lengths
In this paper, new analytical and empirical expressions for the percentage of the star's flux through transparent atmosphere between two wave lengths are developed. For the analytical developments, literal expressi...
Harmonic Matrix and Harmonic Energy
We define the Harmonic energy as the sum of the absolute values of the eigenvalues of the Harmonic matrix, and establish some of its properties, in particular lower and upper bounds for it.
Model Higgs Bundles in Exceptional Components of the Sp(4,R)-Character Variety
We establish a gluing construction for Higgs bundles over a connected sum of Riemann surfaces in terms of solutions to the Sp(4,R)-Hitchin equations using the linearization of a relevant elliptic operato...
A q-VARIANT OF STEFFENSEN'S METHOD OF FOURTH-ORDER CONVERGENCE
Starting from q-Taylor formula, we suggest a new q-variant of Stef-fensen's method of fourth-order convergence for solving non-linear equations.
Inventory Model with Time-Dependent Holding cost under Inflation when Seller Credits to Order Quantity
In this study an inventory model is developed under which the seller provides the retailer a permissible delay in payments, if the retailer orders a large quantity. In this paper we establish an inventory model for non d...
