The rapidly spreading Covid-19 that affected almost all countries, was first reported at the end of 2019. As a consequence its highly infectious nature, countries over world have imposed extremely strict measures to control spread. Since earliest stages this major pandemic, academics done huge amount research in order understand disease, develop medication, vaccines and tests, model Among these studies, great deal effort has been invested estimation epidemic parameters early stage, for by...
Abstract We investigate the self-modulation of Love waves propagating in a nonlinear half-space covered by layer. assume that constituent material layer is nonlinear, homogeneous, isotropic, compressible, and hyperelastic, whereas for half-space, it heterogeneous, compressible different hyperelastic material. By employing thin approximation, problem wave propagation layered reduced to one heterogeneous with modified homogeneous boundary condition on top surface. This new analyzed relevant...
The propagation of dispersive shock waves (DSWs) is investigated in the cylindrical Gardner (cG) equation, which obtained by employing a similarity reduction to two-space one-time ($2+1$) dimensional Gardner-Kadomtsev-Petviashvili (Gardner-KP) equation. We consider steplike initial condition along parabolic front. Then, cG-Whitham modulation system, description DSW evolution cG terms appropriate Riemann-type variables derived. Our study supported numerical simulations. comparison given...
In the standard Susceptible-Infected-Removed (SIR) and Susceptible-Exposed-Infected-Removed (SEIR) models, peak of infected individuals coincides with inflection point removed individuals. Nevertheless, a survey based on data 2009 H1N1 epidemic in Istanbul, Turkey \citep{bib19} displayed time shift between hospital referrals fatalities. An analysis recent Covid-19 \citep{ahmetolan2020can} records for Spanish flu (1918-1919) SARS (2002-2004) epidemics confirm this observation. We use...
Essential properties of the standart Susceptible-Infected-Removed (SIR) model are characterized in terms parameter, R_0, known as basic reproduction number.In present work, we investigate dependency R_0 on contact rates two distinct cases, 2009 A(H1N1) pandemic for Netherlands and Istanbul, Covid-19 federal states Germany. For data from pandemic, encompassing seven European countries (including Netherlands) Turkey, show that number is proportional to population density. We observe particular...

Opinion dynamics of a group individuals is the change in members' opinions through mutual interaction with each other. The related literature contains works which modeled as continuous system, behavioral patterns are analyzed regard to parameters contained system. These models constructed by assumption that independent. Besides, decisions only affected two forces: self-bias force and influence force. In this work we consider nonlinear dynamical system evolution decision under existence...
