In-plane measurements of microelectromechanical systems vibrations with nanometer resolution using the correlation of synchronous images
TL;DR: In this article, the authors report on the development of a versatile vibrometer for characterizing in-plane microelectromechanical systems (MEMS) motion, which combines conventional optical components (microscope objective or macrozoom lens) and a home-made light-emitting diode (LED) stroboscope with incremental phase shifts.
Torque ripple, vibrations, and acoustic noise in switched reluctance motors
TL;DR: The paper presents a state of the art review on the subject of torque ripple, vibrations, and acoustic noise in Switched Reluctance Motors (SRM).
Journal ArticleDOI
Effect of concentration and ignition position on vented methane–air explosions
TL;DR: In this article, the effect of methane concentration and ignition position on pressure buildup and flame behavior was investigated in a 1m3 vessel with a top vent to investigate the effect on pressure.

Experimentally Characterizing the Dynamics of 0.5m+ Diameter Doubly Curved Shells Made From Thin Films
TL;DR: In this article, the results of a series of measurements made to experimentally determine the dynamics of doubly curved very thin film shells are presented first, followed by details of in-vacuum and in-nitrogen tests of the 1.0m diameter sample.

Dynamic stiffness analysis of axially loaded non-uniform Timoshenko columns
Andrew Y. T. Leung,W.E. Zhou +1 more
TL;DR: In this article, a dynamic stiffness matrix is formed by frequency-dependent shape functions which are exact solutions of the governing differential equations of a non-uniform column and the natural frequencies of the nonuniform beams under axial force can be found by equating to zero the determinant of the dynamic stiffness matrices of the system.
