Creating a collimated ultrasound beam in highly attenuating fluids.
We have devised a method, based on a parametric array concept, to create a low-frequency (300-500 kHz) collimated ultrasound beam in fluids highly attenuating to sound. This collimated beam serves as the basis for designing an ultrasound visualization system that can be used in the oil exploration industry for down-hole imaging in drilling fluids. We present the results of two different approac...
متن کاملFinite-amplitude effects on ultrasound beam patterns in attenuating media.
Some problems relevant to medical ultrasonics are addressed through experimental measurements of focused, pure-tone beam patterns under quasilinear conditions where significant nonlinearities are manifested. First, measurements in water provide a comparison of the beam patterns of the fundamental and nonlinearly generated harmonics against recent theoretical predictions of others. The radial be...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولUnfocused Interaction in Distributed Workgroups
Face-to-face human interaction is divided into "focused" and "unfocused" types. Unfocused interaction often conveys important content and context information and contributes to group cohesiveness and effectiveness. Research in Computer Mediated Communication (CMC) and Computer Supported Collaborative Work (CSCW) is also concerned with human interaction. CMC tools, such as electronic mail, and C...
