In this paper, we study the relationship between the standard cellular neural network (CNN) and the resonant tunneling diode (RTD)-based CNN. We investigate the functional and advanced capabilities of a new generation of CNNs that exploit the multiplicity of steady states. We also include in the analysis higher order CNNs. Furthermore, some methods for designing RTD-based CNNs with multiple ste...

Many chemical processes exhibit strong nonlinear dynamic behaviours which may present significant challenges to process operation and control, including input and output multiplicities. Input multiplicity refers to the phenomenon where different inputs (control action) result in the same steady state process output, which is commonly encountered in biochemical reactors. A process with input mul...

The nonlinear behavior of metabolic systems can arise from at least two different sources. One comes from the nonlinear kinetics of chemical reactions in metabolism and the other from nonlinearity associated with regulatory processes. Consequently, organisms at a constant growth rate (as experienced in a chemostat) could display multiple metabolic states or display complex oscillatory behavior ...
