We have been using a phone-based cepstral system with polynomial features in NIST evaluations for the past two years. This system uses three broad phone classes, three states per class, and third-order polynomial features obtained from MFCC features. In this paper, we present a complete analysis of the system. We start from a simpler system that does not use phones or states and show that the a...

Introduction: With the increase in mobile phone usage in public places, the use of mobile phone jammer has also increased therefore, the aim of this study was to evaluate the effects of mobile phone jammer on the level of anxiety in mice. Methods: Forty male and 40 female naive mice (25-30 g) were randomly divided into four groups (control, 900 MHz, 1800 MHz and 900+1800 MHz exposures). Ani...

The main objective of this paper is to argue how the mobile phones have transformed the Iranian lifestyle and how the arrival of mobiles has been a catalyst for revolting behavior, and has launched a new consumer behavior and has changed our relationships. The paper explains how the people's behavior has developed a whole new social code in Iran. It is argued that the social value of being able...

background: mobile phone is one of the most important necessary tools in today’s life which can threaten people’s health in some conditions. the present study was carried out to compare the effect of educational intervention by short message and pamphlet on the behavior of steel factory staff in ardakan, yazd province, iran.materials and methods: the present study was experimentally carried out...

This paper presents a novel framework for HMM-based automatic phonetic segmentation that improves the accuracy of placing phone boundaries. In the framework, both training and segmentation approaches are proposed according to the minimum boundary error (MBE) criterion, which tries to minimize the expected boundary errors over a set of possible phonetic alignments. This framework is inspired by ...

background the increasing use of mobile phones in recent years has caused concerns about the effects of electromagnetic waves of mobile phonesonhuman biological processes. objectives this study was conducted in order to survey the effects of mobile electromagnetic waves on electro cardiogram parameters as heart rate, tp segment, pr interval, time of qrs and t waves, and voltage of r wave. patie...

The majority of research on cell phone use has focused on adolescent and young adult users with less attention on cell phone use by those older than 25 years of age. In this study, adult participants from 18 to 68 years completed a survey about their own use of cell phones and the contexts in which they considered cell phone use appropriate. There were age and gender differences in beliefs abou...

Psychologists typically rely on self-report data when quantifying mobile phone usage, despite little evidence of its validity. In this paper we explore the accuracy of using self-reported estimates when compared with actual smartphone use. We also include source code to process and visualise these data. We compared 23 participants' actual smartphone use over a two-week period with self-reported...

Uroflowmetry, urethrocystoscopy and urethrography are either not readily available or the cost is prohibitive for many patients in low-resource countries. This paper examines the use of clinical history in post-urethroplasty follow-up. We retrospectively reviewed the outcome of 54 post-urethroplasty patients. Preoperative diagnostic work-up included simple blood tests and a retrograde urethrogr...

In this paper, we propose word-level hidden Markov models (HMMs) to supplement state-of-the-art phone-based acoustic modeling in order to enhance the performance of automatic speech recognition (ASR) system. Each word in a vocabulary is initially modeled by well-trained triphone models. Maximum a posteriori adaptation is then applied to generate models for words with a large number of occurrenc...
