Results from variants of the Fisher equation in the study of epidemics and bacteria
نویسنده
چکیده
The Fisher equation, which combines di/usive motion of individuals with nonlinearities arising from their growth and competition processes, is analyzed, generalized, and applied to the dynamics of bacteria, pattern formation, and the spread of epidemics. Analytic solutions are also presented for some exactly soluble and physically relevant variants of the equation. c © 2004 Elsevier B.V. All rights reserved. PACS: 87.17.Aa; 87.17.Ee; 87.17.Jj

New variants of the global Krylov type methods for linear systems with multiple right-hand sides arising in elliptic PDEs
In this paper, we present new variants of global bi-conjugate gradient (Gl-BiCG) and global bi-conjugate residual (Gl-BiCR) methods for solving nonsymmetric linear systems with multiple right-hand sides. These methods are based on global oblique projections of the initial residual onto a matrix Krylov subspace. It is shown that these new algorithms converge faster and more smoothly than the Gl-...
متن کاملQualitative Properties and Existence of Solutions for a Generalized Fisher-like Equation
This paper is devoted to the study of an eigenvalue second order differential equation, supplied with homogenous Dirichlet conditions and set on the real line. In the linear case, the equation arises in the study of a reaction-diffusion system involved in disease propagation throughout a given population. Under some relations upon the real parameters and coefficients, we present some existence ...
متن کاملThe comparison of optimal homotopy asymptotic method and homotopy perturbation method to solve Fisher equation
In recent years, numerous approaches have been applied for finding the solutions of functional equations. One of them is the optimal homotopy asymptotic method. In current paper, this method has been applied for obtaining the approximate solution of Fisher equation. The reliability of the method will be shown by solving some examples of various kinds and comparing the obtained outcomes with the ...
متن کاملFrequency of hospital-acquired methicillin resistant staphylococcus aureus nasal carrier patients, Kermanshah, Iran
Introduction: Methicillin resistant S. aureus nasal carriers may be acquired the bacteria from community or hospital. Hospital-acquired bacteria are antibiotic resistant and encourage the patient and his (her) family to infection. The aim of this study was to determine the frequency of hospital-acquired methicillin resistant Staphylococcus aureus nasal carrier patients. Methods: In this ...
متن کاملCompare Adomian Decomposition Method and Laplace Decomposition Method for Burger's-Huxley and Burger's-Fisher equations
In this paper, Adomian decomposition method (ADM) and Laplace decomposition method (LDM) used to obtain series solutions of Burgers-Huxley and Burgers-Fisher Equations. In ADM the algorithm is illustrated by studying an initial value problem and LDM is based on the application of Laplace transform to nonlinear partial differential equations. In ADM only few terms of the expansion are required t...
