Dispersion curves characterize the frequency dependence of phase and group velocities propagating elastic waves. Many analytical numerical techniques produce dispersion from physics-based models. However, it is often challenging to accurately model engineering structures with intricate geometric features inhomogeneous material properties. For such cases, this paper proposes a novel method estim...

Introduction: The prevalence of hearing loss in neonates is 2-5 out of every 1,000 live births. Global Health Committee, American Academy of Otolaryngology, and American Academy of Pediatrics have recommended that hearing loss in infants be identified, and treated when possible, prior to 6 months of age. This study was designed with the aim to screen the hearing of neonates in Mashhad, Iran. Me...

Abstract: A new frequency response identification method is presented to estimate frequency responses of discrete-time processes. It provides exact frequency response data sets for any desired frequency. This method incorporates various process signal types such as both initial and final steady state, initial steady state and final cyclic steady state and both initial and final cyclic steady st...

The objective of this study is development of driver’s sleepiness using Visually Evoked Potentials (VEP). VEP computed from EEG signals from the visual cortex. We use the Steady State VEPs (SSVEPs) that are one of the most important EEG signals used in human computer interface systems. SSVEP is a response to visual stimuli presented. We present a classification method to discriminate between...

BACKGROUND The auditory steady-state response, which measures the ability of neural ensembles to entrain to rhythmic auditory stimuli, has been used in human electroencephalogram studies to assess sensory processing and electrical oscillatory deficits. Patients with schizophrenia show a deficit in auditory steady-state response at 40 Hz, and therefore this may be a useful biomarker to study thi...
