Measuring second-order time-average pressure
نویسندگان
چکیده
Measurements of the spatial distribution of the time-averaged second-order pressure in a plane standing wave in atmospheric air are reported. Several measurement pitfalls are identified, and solutions are described. These include accounting for slight nonlinearity of the piezoresistive transducer and careful mounting of the transducer. Streaming causes extra complication when a capillary-connected manometer is used. With the proper technique and instrumentation, results are in good agreement with theory. © 2001 Acoustical Society of America. @DOI: 10.1121/1.1382615#

In this research, the reaction kinetics of TiH2 powder in contact with pure aluminum melt at various temperatures on the basis of measuring the released hydrogen gas pressure was studied. To determine the mechanism the reaction, after Solidification of samples, interface of TiH2 powder in contact with melt was studied. The results showed that PH2-time curves had three regions. In the first and...
متن کاملSystematic Approach to Design a Finite Time Convergent Differentiator in Second Order Sliding Mode Controller
This paper presents a systematic approach to design a Lyapunov based super twisting differentiator. The differentiator will be shown convergent in a finite time whilst the relevant time is accurately estimated. This differentiator is the main part to establish the sliding surface in higher order sliding mode. The differentiator is used in the prescribed control structure to regulate pressure...

متن کاملLower esophageal sphincter pressure measurement under standardized inspiratory maneuveurs.
BACKGROUND Through rhythmic variations, the diaphragm influence lower esophageal sphincter (LES) pressure acting as an external sphincter. LES pressure recording is characterized by increased pressure in inspiration due to contraction of the diaphragmatic crura that involves the sphincter. AIM To describe a method of measuring LES pressure during standardized inspiratory maneuvers with increa...
