Anotace:

Biological dynamic systems can be modeled by analytical approaches or by computer supported optimization techniques. Analytical approaches may result in models of population dynamics, bioreactor, epidemiological models, artificial neurons, arterial CO2, or the model explaining chaos in heart rate. The computational intelligence based approaches will be like the prediction of real lung motion during respiration or adaptive monitoring of ECG.
