Automatic Detection of the Common and Non-common Frequencies in Congruent Discrete Spectra. A Theoretical Approach
Cezar Doca, Constantin Paunoiu
Both sampling a time-varying signal, and its spectral analysis are activities subjected to theoretically compelling, such as Shannon's theorem and the objectively limiting of the f…
Limit points and Hopf bifurcation points for a one - parameter dynamical system associated to the Luo - Rudy I model
Cătălin Liviu Bichir, Adelina Georgescu, Bogdan Amuzescu +5
A one - parameter dynamical system is associated to the mathematical problem governing the membrane excitability of a ventricular cardiomyocyte, according to the Luo-Rudy I model.…
Approximation of pressure perturbations by FEM
Cătălin Liviu Bichir, Adelina Georgescu
In the mathematical problem of linear hydrodynamic stability for shear flows against Tollmien-Schlichting perturbations, the continuity equation for the perturbation of the velocit…
Limit cycles by FEM for a one-parameter dynamical system associated to the Luo-Rudy I model
Cătălin Liviu Bichir, Adelina Georgescu, Bogdan Amuzescu +5
An one-parameter dynamical system is associated to the mathematical problem governing the membrane excitability of a ventricular cardiomyocyte, according to the Luo-Rudy I model. L…
A new modified Galerkin method for the two-dimensional Navier-Stokes equations
Anca-Veronica Ion
We present a new type of modified Galerkin method. It is a construction with several (inductively defined) levels, that provides approximate solutions of increasing accuracy with e…
