"This work contains the results from the simulations performed according to two computational models. The first one referrs to a chemical system within a Continuosly tirred Tank Reactor (CSTR), while the second deals with a physico-chemical system of self-assembling pieces under different conditions. In addition, two mathematical analyses are also included. One is for waves along microtubules at the brain scale and the other is a wavelet processing of data from time series of Elementary Cellular Automata (ECA). The results of this thesis are mainly based on cellular automata as a tool for modeling and producing complex spatio-temporal dynamics"
