Multi-level and multidisciplinary optimisation of microelectromechanical systems

Michael Farnsworth
TL;DR: A comparative investigation into the role multi-level and multidisciplinary design optimisation can play in the automated design synthesis of microelectromechanical systems (MEMS) is presented and a novel modular soft computing framework is developed to house the multi-objective, multi- level and multiidisciplinary designs optimisation strategies.

The hydrid model for SAW filter

Trang Hoang, +4 more
TL;DR: The hybrid model is proposed and has a good agreement with measurement and would be helpful to design SAW filter that takes into account the distance between two IDTs, and therefore, is also helpful for design Sawsaw based pressure sensor in which the applied pressure will change thedistance between twoIDTs.
