This work studies the squeeze film effects in dynamic MEMS devices. The emphasis is on the development of compact analytical models due to their amenability in device level simulations using lumped parameters. To provide context to the current work first the computational efficacy of lumped parameter modelling of dynamic MEMS devices is demonstrated in MATLAB/Simulink software environment using a MEMS gyroscope and a MEMS microphone as examples. This is followed by a detailed comparative study of equivalent electrical circuit models for a MEMS microphone wherein the importance of accurate extraction of lumped mass, stiffness and damping due to squeeze film is brought into focus. Consistent expressions are derived for equivalent mass and stiffness of plate and beam structures using Rayleigh's energy methods. Discrepancies in modelling compressible squeeze film are brought out and the need for an in depth study of squeeze film behaviour is highlighted leading to a strong motivation for the development of compact squeeze film models.

The politics of cutting public spending or raising taxes (or both) has dominated politics in many democracies in recent years. A new era of conflict has developed, with old political alignments being tested and new battles emerging over whose expectations are to be disappointed and who should be blamed for fiscal squeeze.Do parties who cut spending always go down to defeat in elections? Are there 'best practice' cases that every government should follow when it has to cut spending or raise taxes to balance its public finances? Such issues have mainly been analysed from an economic or financial perspective and in the context of recent cases. By contrast, this book focuses on the politics of fiscal squeeze and takes a longer view.It combines quantitative and qualitative analysis to examine cases ranging from the fiscal squeeze in the United States in the 1830s/40s (when half of the states then in the Union defaulted) to the squeeze following the 2001 Argentinian default. It assesses who were the winners and losers, who got the blame and what were the longer-term effects on politics and government. It argues that 'how to do it' approaches to fiscal squeeze in democracies, based on apparently successful cases, often failto take into account profound differences in circumstances.

Vibrations of Elastic Systems
249,98 € *
ggf. zzgl. Versand

This work presents a unified approach to the vibrations of elastic systems as applied to MEMS devices, mechanical components, and civil structures.Applications include atomic force microscopes, energy harvesters, and carbon nanotubes and consider such complicating effects as squeeze film damping, viscous fluid loading, in-plane forces, and proof mass interactions with their elastic supports. These effects are analyzed as single degree-of-freedom models and as more realistic elastic structures. The governing equations and boundary conditions for beams, plates, and shells with interior and boundary attachments are derived by applying variational calculus to an expression describing the energy of the system. The advantages of this approach regarding the generation of orthogonal functions and the Rayleigh-Ritz method are demonstrated.A large number of graphs and tables are given to show the impact of various factors on the systems' natural frequencies, mode shapes, and responses.
