Permafrost is sensitive to climate change and anthropogenic activities. The interferometric synthetic aperture radar (InSAR) is a new technology allowing us to explore the interaction between the permafrost change and human infrastructures. In this paper, the deformation of the Qinghai-Tibet Railway (QTR) in Beiluhe of the Tibet Plateau (TP) between Jun. and Dec. 2014 is detected using the new mode...
Generally speaking the permafrost in the Tibet region is influenced by the global climate change. The synthetic aperture radar interferometry (InSAR) could detect the surface uplift/subsidence in millimeter-level resolutions, which is powerful for the permafrost monitoring. In recent years, high-resolution synthetic aperture radar (SAR) with centimeter-level resolution makes it possible to explore...
For electrostatically actuated parallel-plate tunable Microelectromechanical System (MEMS) capacitors in traditional theory, pull-in occurs when the deflection of the movable plate is one-third of the original air gap. In this paper, we fabricated the parallel-plate tunable MEMS capacitors and used WYKO NT1100 optical surface profiler to measure the displacement related with deformation. The results...
