This paper is focused on a novel design of stepped diaphragm for MEMS capacitive pressure sensor used in tire pressure monitoring system. The structure of sensor diaphragm plays a key role for determining the sensitivity of the sensor and the non-linearity of the output.First the structures of two capacitive pressure sensors with clamped square flatdiaphragms, with different thicknesses are inv...

in the current attempt, the relation between precipitation change in southern coasts of iran and sea level pressure data of ncep / ncar database were investigated through correlation method using environment to circulation approach in the period of 1960-2004. after calculating the correlation matrix between the percipitation amount and pressure, the precipitation-pressure correlation map for ea...

Laser-enhanced cavitation during high intensity focused ultrasound (HIFU) was studied in vivo using a small animal model. Laser light was employed to illuminate the sample concurrently with HIFU radiation. The resulting cavitation was detected with a passive cavitation detector. The in vivo measurements were made under different combinations of HIFU treatment depths, laser wavelengths, and HIFU...
