The noise immunity of radio communication systems based on IEEE 802.15.4–2020 and 802.15.4z–2020 standards under interference effect variable-duration impulse is investigated. simulation model a channel for estimation the bit error rate with different parameters developed using MATLAB. estimates standard modes taking into account structure transmitted data are obtained. comparison between chara...

In this paper, we explore lifetime private mobility milestones in Greece and identify the factors that affect them, to everchanging landscape. total, five archetypal were examined: age of getting a car driving license period until following that; motorbike license; first bicycle as an adult; traveling by airplane. To end, duration modeling namely Kaplan-Meier Cox Proportional Hazards models dev...

This paper introduces frame-based Gaussian process regression (GPR) into phone/syllable duration modeling for Thai speech synthesis. The GPR model is designed for predicting framelevel acoustic features using corresponding frame information, which includes relative position in each unit of utterance structure and linguistic information such as tone type and part of speech. Although the GPR-base...

This study reports a case of consonant-induced duration compensation within a higher phonological unit in Korean. The main finding of this study is that longer duration in a consonant is partly compensated by shorter duration even in non-adjacent consonants. Results of experiments revealed that the shortening in non-adjacent consonants is a subsidiary compensation process to maintain constant d...

The large pronunciation variability of words in conversational speech is one of the major causes of low accuracy for automatic speech recognition (ASR). Many pronunciation modeling approaches have been developed to address this problem. Some explicitly manipulate the pronunciation dictionary as well as the set of the units used to define the pronunciations of words. Others model the pronunciati...

in order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the college of agriculture, shiraz university, shiraz, iran during 2010 and 2011 growing seasons. two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...

In this paper we analyze three different approaches to improving the quality of an HMM-based speech synthesizer by means of an external duration model. The first approach uses the external duration model in a standard way to define the phone duration during synthesis. The second is a novel approach that uses the phone duration to create additional context features for the decision trees cluster...

OBJECTIVE A growing number of studies indicate that shorter sleep durations could contribute to obesity in children. The objective of this article was to further examine the longitudinal relationship between sleep duration and body mass index (BMI) in children by using a growth mixture modeling approach. METHOD This article used prospective data from the Longitudinal Study of Australian Child...
