CONTEXT Acoustic radiation force impulse imaging is an emerging imaging modality. The study of the pancreas is a new and promising application of ultrasound acoustic radiation force impulse imaging. CASE REPORT We present the first case of pancreatic serous cystadenoma which mimics a solid neoplasm at conventional imaging (US and CT), correctly diagnosed as cystic at ultrasound acoustic radia...

In this paper, we propose an acoustic model training technique which is robust against outliers such as clipping, unexpected noise, poorly pronounced word segments, or mistranscriptions, which deteriorate the quality of the acoustic models and in turn decrease speech recognition performance. The outlier-robust acoustic model training technique is based on a maximum likelihood (ML) criterion and...

Most studies on speech-based emotion recognition are based on prosodic and acoustic features, only employing artificial acted corpora where the results cannot be generalized to telephone-based speech applications. In contrast, we present an approach based on utterances from 1,911 calls from a deployed telephone-based speech application, taking advantage of additional dialogue features, NLU feat...

As a child acquires language, he or she: perceives acoustic information in his or her surrounding environment; identifies portions of the ambient acoustic information as languagerelated; and associates that language-related information with his or her perception of his or her own language-related acoustic productions. The present work models the third task. We use a semisupervised alignment alg...

Received Jan 16, 2018 Revised Mar 18, 2018 Accepted Mar 31, 2018 Piezoelectric Acoustic Transducer (PAT) is a transducers used in many application such as medical diagnostic, medical ultrasonic imaging and underwater acoustic applications. Latest research, PAT were investigated in marine application and underwater acoustic imaging. Conventional PAT is design based on sensing element, Piezoelect...

This paper presents a newly developed hybrid simulation technique for coupled structural-acoustic analysis, which applies a wave based model for the acoustic cavity and a modally reduced finite element model for the structural part. The resulting hybrid model benefits from the computational efficiency of the wave based method, while retaining the finite element method’s ability to model the str...

Methods and systems for identifying and spatially localizing tissues having certain physiological properties or producing certain biological responses, such as the sensation of pain, in response to the application of intense focused ultrasound (acoustic probing or palpation) are provided. In some embodiments, targeted acoustic probing is employed to iden tify the scope and severity of chronical...

background: the primary goal of antenatal testing is to identify fetuses at risk of intrauterine neurologic injury or death so that these adverse outcomes can be prevented. we want to assess nonstress test (nst) results and some parameters before and after vibro-acoustic stimulation and acupressure. we did a randomized controlled clinical trial in shahid-beheshti hospital in isfahan in 2011. ma...
