Determinación de parámetros del modelo exponencial mediante una aplicación móvil

Abstract

This work, shows the development of a mobile application for the Android Operative System, which calculates many parameters of exponential model (or Malthusian model) if the number of microorganisms in two different times is known. From the solution of a differential equation and the properties of the exponential function, a button is programmed to determine the constant of growth, the doubling time, the initial population, and the quantity at a different time, with the data entered by the user. An example shows the validity of the results of the app when compared with those that are obtained manually.
