Optimal control of a bioreactor for biofuel production
Roberta Ghezzi, Benedetto Piccoli
Dynamic flux balance analysis of a bioreactor is based on the coupling between a dynamic problem, which models the evolution of biomass, feeding substrates and metabolites, and a l…
BV functions and sets of finite perimeter in sub-Riemannian manifolds
Luigi Ambrosio, Roberta Ghezzi, Valentino Magnani
We give a notion of BV function on an oriented manifold where a volume form and a family of lower semicontinuous quadratic forms are given. When we consi…
Regularization of chattering phenomena via bounded variation control
Marco Caponigro, Roberta Ghezzi, Benedetto Piccoli +1
In control theory, the term chattering is used to refer to strong oscillations of controls, such as an infinite number of switchings over a compact interval of times. In this paper…
Hausdorff measures and dimensions in non equiregular sub-Riemannian manifolds
Roberta Ghezzi, Frédéric Jean
This paper is a starting point towards computing the Hausdorff dimension of submanifolds and the Hausdorff volume of small balls in a sub-Riemannian manifold with singular points.…
