rate of exponential decayexponential stabilityThe exponential decay rate of a Timoshenko beam system with boundary damping is studied. By asymptotically analyzing the characteristic determinant of the system, we prove that the Timoshenko beam system is a Riesz system; hence, its decay rate is ...
In this paper we estimate the worst rate of exponential decay of degenerate gradient flows \\dot x = -S x \\dot x = -S x , issued from adaptive control theory. Under persistent excitation assumptions on the positive semi-definite matrix S S , we provide upper bounds for this rate of ...
Moreover, the unique \\({2\\pi}\\) -periodic solution is (exponentially asymptotically stable) and its rate of exponential decay c /2 is sharp. The new criterion characterizes \\({g_{x}^{\\prime}(t, x) - c^2/4}\\) with L p -norms \\({(p \\in [1, \\infty])}\\) ...
λ = rate of decay constant t = time Taking the natural log of both sides of this equation (remember it is an exponential decay) will yield: Rate of Decay Formula Questions: 1. Calculate the rate of decay constant for U-238 if its half-life is 4.468 × 109years. Answer: If the pro...

Roughly, in the context of linear equations, it can be formulated as the problem of producing the exponential decay of solutions through the use of suitable dissipative feedback mechanisms. The main differences with respect to controllability problems are that: • in controllability problems the ...

Using a method developed by Foias and Temam [J. Funct. Anal.87, 359 (1989)], exponential decay of the spatial Fourier power spectrum for solutions of the incompressible Navier–Stokes equations is established and explicit rigorous lower bounds on a small length scale defined by the exponentia...
