To encourage a mental flow state, I listen to 'zone music'. Whenever I have to concentrate, I turn this music on.
The songs below are also a Pomodoro 25min so it's break time when the song ends.

Totally off topic, but it relates to a few posts I made 5-10 years ago.  INFOMANIA. ALIVE & WELL. One of my interests is the study of “Infomania”, a syndrome described by Hewlett Packard R…

Learning-Based Stable Optimal Control for Infinite-Time Nonlinear Regulation Problems
Infinite-time nonlinear optimal regulation control is widely utilized in aerospace engineering as a systematic method for synthesizing stable controllers. However, conventional methods often rely on linearization hypothesis, while recent learning-based approaches rarely consider stability guarantees. This paper proposes a learning-based framework to learn a stable optimal controller for nonlinear optimal regulation problems. First, leveraging the equivalence between Pontryagin Maximum Principle…

Well--posedness for the biharmonic scattering problem for a penetrable obstacle
We address the direct scattering problem for a penetrable obstacle in an infinite elastic two--dimensional Kirchhoff--Love plate. Under the assumption that the plate's thickness is small relative to the wavelength of the incident wave, the propagation of perturbations on the plate is governed by the two-dimensional biharmonic wave equation, which we study in the frequency domain. With the help of an operator factorization, the scattering problem is analyzed from the perspective of a coupled bou…
