The present paper tries to determine the spatial structure and the time behaviour of cell renewal systems. For this purpose a computer model for the two-dimensional cell space was developed, which is described by a set of specifications and growth statements.
Regarding the development of this model special emphasis was given to -the existence of several cell systems with different mean life spans, -the variability of the initial configuration of cell patterns, -the description of cell-to-cell interactions, -the perturbation of normal cell growth by tumor cells and their elimination, in medicine comparable with a removal by surgery or by irradiation, -the consideration of the loss of tumor cells, In the future it seems to be possible to partly substitute long and expensive biological experimental test series by simulation with the help of these models.

In this study, we use the cell dynamics method to test the validity of the Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory of phase transformation. This cell dynamics method is similar to the well-known phase-field model, but it is a more simple and efficient numerical method for studying various scena
We investigate the optical and electrical properties of thin-®lm silicon solar cells by means of numerical simulations. The optical design under investigation is the encapsulated-V texture, which is capable of absorbing sunlight corresponding to a maximum short-circuit current density of 35 mA cm À2
