Eigenvalue Analysis and Model Reduction in the Treatment of Disc Brake Squeal

By Volker Mehrmann , Christian Schröder
Disc brake squeal is a frequent and annoying phenomenon. To improve the situation, a group initiated a joint project to develop a mathematical model of a brake system with all effects that may cause squeal and to generate a small-scale reduced-order model that can be used for optimization.

Leveraging Noise to Control Complex Networks

By Daniel K. Wells, William L. Kath, Adilson E. Motter

Despite stochasticity's far-reaching outcomes, noise has been regarded as little more than a nuisance in the development of methods to control real network systems. Here the authors illustrate ways through which noise can be accounted, and in fact exploited, to control network dynamical systems.

Energy Optimization (Rain Is Free, or Isn’t It?)

By Claudia Sagastizábal

Electricity poses a difficult challenge, as an electrical network should carry power in an amount that is “enough” without being “too much.” Given these constraints, how can one generate electricity in a manner that is both satisfactory for consumers and efficient from the network point of view? Optimization provides an answer.
