Energetic wave equation for modelling diffuse sound fields. I: corridor case

In previous studies, we explored the effect of different ambient sounds (vocal vs. non- vocal) in such public areas as a car park and a metro station, and demonstrate the effect of

If ϕ does not vanish identically on any subset of [0, π] of positive measure then the undetermined case does not occur, the optimal control a (which is said bang-bang) is

In particular, we define and completely solve a convexified version of this problem, underline a generic non existence result with respect to the values of the measure constraint L,

In nine numbered sections, without words, with sub-titles, a similar version to the one in Shenqi mipu.. In twelve numbered sections, with words and sub-titles, a similar version to

We wish to make clear that our result, namely that Levinsons’ theorem is an index theorem, is quite different from a result encountered in supersymmetric quantum mechanics about

(W defines the angle of the wave vector with respect to f the normal of the layers figure 1). The main difficulty with traditional techniques such as Brillouin scattering
