We propose the notion of nearly invariant set for an ordinary differential equation to give a clear mathematical meaning to the notion of quasi-steady state (QSS) in equations describing chemically reacting systems. We show that this approach is sensible in view of the intended applications. More...

We prove the existence of steady space quasi-periodic stream functions, solutions for the Euler equation in a vorticity-stream function formulation in the
(n = ∞). These photobleaching peaks align with those observed in the steady-state absorption spectrum. TA spectra of quasi-2D films closely resemble those of low-dimensional 2D perovskite films, except for the absence of the 740 nm peak in the 2D films. Therefore, TA measurements ...
The fourth stage: the storage energy in the microstructure is reduced, the DRX is gradually weakened, the curve should tend to flatten out and enter the steady state, but due to the emergence of the cavity, long-distance horizontal flow phenomenon, usually occurring in the nominal stress-...
The key of our analysis is a linearization around an approximation of the steady state of the problem, and the reduction of the dynamics to a one-dimensional motion, describing the slow convergence of the interfaces towards the equilibrium....
Right before the episode, we start to observe a steady increase in IR responses until approximately 9 weeks after an event, when the increase reaches its maximum. Then, the curve starts to decline to the baseline level at about 20 weeks after the event. Similar results were shown in ...

Upward and downward sweeps of the forcing frequency are performed and for each frequency 5000 (¼ 10Q1) cycles are simulated to reach the steady state regime and collect time history data. The time step adopted is 1/500 of the forcing period 2p=X. Results are plotted in Fig. 14a). ...
During steady-state operation, water mist104is sprayed into ambient air102of compressor106. This results in the outlet air temperature being almost the same as the inlet air temperature, making the compression “quasi-isothermal.” To achieve the benefits of the quasi-isothermal compressor, it may...
