A phononic crystal of aluminum rods with an asymmetric cross section in water is used for the study Anderson localization sound. Due to asymmetry, these scatterers may be arranged three different configurations: a periodic 2D structure, random structure disorder, and 1D disorder. The last configuration where are equally oriented within columns disoriented along rows fabricated experimental syst...

communication disorder is a widespread disabling problems and associated with adverse, long term outcome that impact on individuals, families and academic achievement of children in the school years and affect vocational choices later in adulthood. the aim of this study was to determine prevalence of speech disorders specifically stuttering, voice, and speech-sound disorders in primary school s...

In this paper, an extreme learning machine with an automatic segmentation algorithm is applied to heart disorder classification by heart sound signals. From continuous heart sound signals, the starting points of the first (S1) and the second heart pulses (S2) are extracted and corrected by utilizing an inter-pulse histogram. From the corrected pulse positions, a single period of heart sound sig...

Assisting physicians in the auscultation of the patients by providing less costly, automatic and accurate signal processing module for the heart event detection and recognition is of great importance. This paper presents a complete heart sound analysis system covering from the segmentation of beat cycles to the final determination of heart conditions. A basic task for the diseases diagnosis fro...

PURPOSE: The present study examined associations of 5 endophenotypes (i.e., measurable skills that are closely associated with speech sound disorders and are useful in detecting genetic influences on speech sound production), oral motor skills, phonological memory, phonological awareness, vocabulary, and speeded naming, with 3 clinical criteria for classifying speech sound disorders: severity o...

OBJECTIVE To identify a cutoff value based on the Percentage of Consonants Correct-Revised index that could indicate the likelihood of a child with a speech-sound disorder also having a (central) auditory processing disorder . METHODS Language, audiological and (central) auditory processing evaluations were administered. The participants were 27 subjects with speech-sound disorders aged 7 to ...
