This paper presents a new polyhedral approximation for the quadratic cost curve of thermal units for the unit commitment problem. The approximation is tight, can be represented by rational numbers, and its size grows ...

We use the regularization theory in a Bayesian framework to derive a quadratic cost function for denoising fringe patterns. As prior constraints for the regularization problem, we propose a Markov random field model that ...

This paper deals with the problem of regional guaranteed cost control design for, possibly open-loop unstable, nonlinear quadratic systems with a delayed state. Control methods based on the Razumikhin and Lyapunov-Krasovskii ...

We study the probabilistic behaviour of the continued fraction expansion of a quadratic irrational number, when weighted by some "additive" cost. We prove asymptotic Gaussian limit laws, with an optimal speed of convergence. ...
