How can the Gradual Development of More Sustainable Energy Systems Be Integrated in Urban Planning in China?

Great efforts have been made in China to reduce coal consumption over the last decade. However, the energy transition to more sustainable energy systems will be gradual and take a longer time than expected. This paper discusses how sustainable development of energy systems on the local level can be gradually achieved. A challenge will be to...

A new robust design for imperfection sensitive stiffened cylinders used in aerospace engineering

A knock-down factor is commonly used to take into account the obvious decline of the buckling load in a cylindrical shell caused by the inevitable imperfections. In 1968, NASA guideline SP-8007 gave knock-down factors which rely on a lower-bound curve taken from experimental data. Recent research has indicated that the NASA knock-down factors...

Chaotic Dynamics in Smart Grid and Suppression Scheme via Generalized Fuzzy Hyperbolic Model

This paper presents a method to control chaotic behavior of a typical Smart Grid based on generalized fuzzy hyperbolic model (GFHM). As more and more distributed generations (DG) are incorporated into the Smart Grid, the chaotic behavior occurs increasingly. To verify the behavior, a dynamic model which describes a power system with DG is...
