Location optimized hybrid damping for one-dimensional flexible structures

Damping vibrations of flexible structures is a subject of importance in several industries, as the aerospace and high-tech industry. Especially when the ratio of damping over weight needs to be high. In literature optimization of this ratio is achieved in several manners, through optimization of individual damping methods, ie. active and passive...

Routing strategy including time and carbon dioxide emissions: effects on network performance

Traffic congestion leads to delays and increased carbon dioxide (CO2) emissions. Traffic management measures such as providing information on environmental route costs have been proposed to mitigate congestion. Multi-criteria routing dynamic traffic assignment (MCR-DTA) models are needed to evaluate the effectiveness of such measures. This paper...
