Acoustic Waves in Bubbly Soft Media
There exists a special class of solid media called soft media (or weakly compressible media), for which the inequality ┣>>┤ is satisfied (┣ and ┤ are the Lamé coefficients) [1-6]. Such media with very small shear stiffness are dynamically similar to liquids to a great extent and exhibit strongly a “water-like” characteristic and, therefore, are also associated with the name of “water-like” medi...
متن کاملLocalization of Classical Waves I : Acoustic Waves
We consider classical acoustic waves in a medium described by a position dependent mass density %(x). We assume that %(x) is a random perturbation of a periodic function % 0 (x) and that the periodic acoustic operator A 0 = ?r 1 % 0 (x) r has a gap in the spectrum. We prove the existence of localized waves, i.e., nite energy solutions of the acoustic equations with the property that almost all ...
متن کاملExcitation and resonance of acoustic-gravity waves in a column of stratified, bubbly magma
Oscillations of magma in volcanic conduits are thought to be the source of certain seismic and infrasonic signals observed near active volcanoes. However, the multiphase and stratified nature of magma within the conduit complicates the calculation of resonant modes that is required to interpret observations. Here we present a linearized mathematical framework to describe small-amplitude oscilla...

هدف این رساله تحقیق در مورد یافتن ارتباط بین واحدهای درک مطلب (از قبیل پروسه واژگانی، پروسه ساختاری و پروسه تفسیر معنایی) از طریق تست کلوز چهار چوابی در بین دانشجویان سال آخر رشته زبان انگلیسی میباشد. در مرحله اول از 150 دانشجو (80 مونث و 70 مذکر) از بین دانشجویان کارشناسی و کارشناسی ارشد دانشگاههای علامه طباطبائی، دانشگاه شهید بهشتی و دانشگاه آزاد اسلامی واحد شمال تست نلسون (450 دی) گرفته شد. ...
15 صفحه اولImprovement of acoustic theory of ultrasonic waves in dilute bubbly liquids.
The theory of the acoustics of dilute bubbly liquids is reviewed, and the dispersion relation is modified by including the effect of liquid compressibility on the natural frequency of the bubbles. The modified theory is shown to more accurately predict the trend in measured attenuation of ultrasonic waves. The model limitations associated with such high-frequency waves are discussed.
