In this randomized, cross-over cadaver study, we determined whether a new airway device, the ProSeal laryngeal mask airway (PLMA; Laryngeal Mask Company, Henley-on-Thames, UK), prevents aspiration of regurgitated fluid. We studied five male and five female cadavers (6-24 h postmortem). The infusion set of a pressure-controlled, continuous flow pump was inserted into the upper esophagus and liga...

The design and test of a frequency channel selection MEMS filter implemented on a commercial CMOS technology is presented. Mechanical coupling between two clamped-clamped beams is used to obtain 0.5% frequency bandwidth in a tunable 26 MHz bandpass filter with a very low bandpass distortion (less than 0.1 dB), which makes the filter suitable for wireless super-hetherodyne transceivers in commun...

Abstract In this paper, free vibration and transmission response for the torsional of circular annular plate are presented. To author’s knowledge, few studies can be found from wave standpoint. For purpose, in study, natural frequencies with clamped–clamped free–free boundaries calculated. The obtained by approach compared those derived classical method. Furthermore, transmissibility curves per...

-In this paper, comparative evaluation of different techniques for harmonic reduction in input current of ac-dc converter is presented. Converters employing ac side switching, resonant converter, active clamped boost converter are simulated in PSIM and their performance under varying load condition with load voltage regulation is evaluated. The results revealed that active clamped boost convert...

Based on analysis of basic cubic spline interpolation, the clamped cubic spline interpolation is generalized in this paper. The methods are presented on the condition that the first derivative and second derivative of arbitrary node are given. The Clamped spline and Curvature-adjusted cubic spline are also generalized. The methods are presented on the condition that the first derivatives of arb...
