Research ArticleOpen accessIn the abstractEffects of Noises on Fujisaki’s Model of Fundamental Frequency Contours for Thai DialectsSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Modeling of fundamental frequency (F0) contour plays an important role on the natural speech processing, since F0 is an important speech feature defining the human speech prosody. In Thai, there are four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions. Environmental noises are also plays an important role … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 6,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Study of Fujisaki’s Model of Fundamental Frequency Contour for Thai TonesSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Tone of a tonal language is an important feature of a prosodic syllable to identify the meanings of that syllable or that part of word. Ii is very crucial to model the feature related to tone of speech to achieve the most naturalness in speech communication. Approach: The study presents an approach to analyze the model parameters of … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 6,997 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneral Circulation in the Malacca Strait and Andaman Sea: A Numerical Model StudySyamsul Rizal, Peter Damm, Mulyadi A. Wahid et al.In the Andaman Sea and Malacca Strait, as in other parts of the Indian Ocean, the seasonal change of the wind plays a most important role: the south-west (hereafter SW) is monsoon active from June through September and the north-east (hereafter NE) monsoon is active from December through February. During the NE monsoon the winds are directed from the north … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 11 Aug 2012 · 18,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractFujisaki’s Model of Thai’s Fundamental Frequency Contours with Environmental NoisesSuphattharachai Chomphan, Chutarat ChompunthProblem statement: An important human speech feature is the fundamental frequency (F0) contour which represents the speech prosody. It indicates the naturalness and intelligibility of the speech. Modeling of fundamental frequency contour was an essential procedure in the natural speech processing. In speech communication, environmental noise plays an essential role in damaging the digital communication quality. The study of effects … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractGinger Supplementation Enhances Working Memory of the Post-Menopause WomenNaritsara Saenghong, Jintanaporn Wattanathorn, Terdthai Tong-Un et al.Problem statement: Cognitive impairment is one important problem in post-menopausal women. Although hormone therapy can improve this condition, it also produces adverse effect. Recent findings showed that this condition could be mitigated by the herb. Ginger or Zingiber officinale Roscoe, a plant in a family of Zingiberaceae, was previously demonstrated the neuroprotection and cognitive enhancing effects. Therefore, this study was … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 10 Oct 2011 · 10,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractFujisaki's Model of Fundamental Frequency Contours for Thai DialectsSuphattharachai ChomphanProblem statement: In general, there are a number of rural dialects in Thai. However, four dialects are mainly spoken by Thai people residing in four core region including central, north, northeast and south regions. Recognizing and synthesizing Thai speech with different dialects are consequently difficult. Approach: Prosody is an important factor that must be taken into account, since the prosody … …Journal of Computer Science, Vol. 6, Issue 11 · 19 Nov 2010 · 7,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractSH Waves Diffusion in Fluid-Saturated MediumC.C. Dennis Ling, S. Y. Faisal, A. A. ZainalProblem statement: Characteristics of the seismic waves have been studied mainly the amplitudes, attenuation, frequency, porosity and the velocity of the waves. In this study, the SH-waves were studied for the diffusion which was related to the diffraction of SH-waves in the saturated medium. Approach: The elastic wave equation was being used to show the SH-waves. A comparison was made … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 7,336 accessesView PDFCite
Research ArticleOpen accessIn the abstractFull Model Wind Tunnel Study on the Xia-Zhang Bridge Under Operation StageAyad Thabit Saeed, Zhang Liang Liang, Yang Zhuan Yun et al.Problem statement: Long-span cable-stayed bridges under service and particular construction conditions are very susceptible to wind action due to their great flexibility, so the aerodynamic stability is becoming a major concern in the design and construction phrases. Cable-stayed bridges may exhibit wind-induced vibration phenomena such as flutter, buffeting and vortex oscillation under wind excitation. The study concentrated on the issues … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Study on Fundamental Frequency Contours of Thai Expressive Speech Using Fujisaki's ModelSuphattharachai ChomphanProblem statement: In spontaneous speech communication, prosody is an important factor that must be taken into account, since the prosody effects on not only the naturalness but also the intelligibility of speech. Focusing on synthesis of Thai expressive speech, a number of systems has been developed for years. However, the expressive speech with various speaking styles has not been accomplished. … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Ibuprofen and Paracetamol in Binary Mixture Using Chemometric-Assisted Spectrophotometric MethodsWafaa S. HassanThree methods are presented for simultaneous determination of ibuprofen and paracetamol without previous separation. The first method depends on first derivative UV spectrophotometry, with zero-crossing measurement. The first derivative amplitudes at 230 and 290 nm were selected for the assay of ibuprofen and paracetamol, respectively. The second method depends on first derivative of the ratio-spectra by measurements of the amplitudes … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,205 accessesView PDFCite
