Numerical Study of Convective Heat Transfer in Flat Tube Heat Exchangers Operating in Self-Sustained Oscillatory Flow Regimes
… devices operating in flow regimes in which self-sustained oscillations occur were performed. The unsteady flow regimes were transition flow regimes characterized by cyclic variations of flow parameters such as stream-wise or cross-stream velocity. A computer code was developed to perform the …

Mechanistic models of oceanic nitrogen fixation
… I find, in certain parameter regimes, self-sustained oscillations in nitrogen fixation, community structure and biogeochemical cycles even with perfectly steady physical forcing. The period of the oscillations is strongly regulated by the exchange rate between the thermocline and …

Nonlinear Dynamics of solitary and optically-injected spin vertical-cavity lasers
… Various forms of oscillatory behaviour causing self-sustained oscillations in the polarisation of the spin-VCSEL subject to Continuous-Wave (CW) pumping are found. Additionally, this work is extended to study experimentally and theoretically the evolution of the output polarisation ellipticity, …

Modeling and simulation of non-linear bioelectronic systems applied to cell culture assays
… Stability Criterion (BSC) to ensure that self-maintained and self-sustained oscillations are generated. The technique is known as Oscillation Based Test (OBT) [1]. Instead of measuring the changes between the output and input signal, the oscillation frequency and amplitude are acquired …
