Motivated by the periodic behaviour of regulatory networks within cell biology and neurology, we have studied the periodic solutions of piecewise-linear, first- order differential equations with identical relative decay rates. The flow of the solution trajectories can be represented qualitatively by a di...
This optimal decay rate is possible because normal meshes automatically generate a polyline (piecewise linear) approximation of each discontinuity, unlike the blocky piecewise constant approximation of tensor product wavelets. In this way, the proposed nonlinear multiscale normal mesh decomposition is an ...
2.2.2 Piecewise constant reduction of the full Mumford–Shah model The piecewise constant active contour model (Chan and Vese, 2001a; Chan et al., 2000; Cohen, 1997) is a practical variant of the full Mumford–Shah model. Instead of using a piecewise smooth function f to approximate the ...

It should be mentioned, the zero decay of edge modes is due to the way we choose the imaginary part of the on-site energies. However, even if we choose the imaginary part in a different way so that edge modes also decay, both the real and imaginary spectrum of edge modes are still ...
For all examples, we set e = 1 / 2 and the number of points per partition to be constant, i.e., m k ( i ) = m = 2 N + 1 . A precision of 200 digits is used. 5.1. Norms The supremum norm has a theoretical advantage. However, its computation is slower than that of the ...
For a higher air velocity in the tunnel (𝑣𝑥=𝑣𝑥𝑚≥3vx=vxm≥3 m/s), parameter k(vx) is nearly constant and equal to a mean value of 1.1 m/s, with an error <5%, thus substantially confirming the results found by [17] and the validity of the third assumption (c) “...

The steady-state response of an infinite Euler–Bernoulli beam resting on a homogeneous and linear Winkler foundation to a moving constant load was derived using different methods (e.g., time-domain method, transform method) in, for example, [42]. Accounting also for the viscous damping of ...
