• ### Unstructured modelling growth of Lactobacillus acidophilus as a function of the temperature

Unstructured modelling growth of Lactobacillus acidophilus as a function of the temperature: We present modelling software developed under MATLAB in which parameter estimations are obtained by using non-linear regression techniques. The different parameters appear in a set of non-linear algebraic and differential equations representing the model of the process. From experimental data obtained in discontinuous cultures a representative mathematical model (unstructured kinetic model) of the macroscopic behaviour of Lactobacillus acidophilus has been developed.

• ### STOCHASTIC DYNAMICS Modeling Solute Transport in Porous Media

We have attempted to explain the concepts which have been used and developed to model the stochastic dynamics of natural and biological systems. While the theory of stochastic differential equations and stochastic processes provide an attractive framework with an intuitive appeal to many problems with naturally induced variations, the solutions to such models are an active area of research, which is in its infancy. Therefore, this book should provide a large number of areas to research further.

• ### Mathematical Problems in Semiconductor Physics

The increasing demand on ultra miniturized electronic devices for ever improving performances has led to the necessity of a deep and detailed understanding of the mathematical theory of charge transport in semiconductors.

• ### PHYSICS AND FRACTAL STRUCTURES

The end of the 1970s saw the idea of fractal geometry spread into numerous areas of physics. Indeed, the concept of fractal geometry, introduced by B. Mandelbrot, provides a solid framework for the analysis of natural phenomena in various scientific domains. As Roger Pynn wrote in Nature, “If this opinion continues to spread, we won’t have to wait long before the study of fractals becomes an obligatory part of the university curriculum.”
