Research ArticleOpen accessEvery word in the titleStructural Modeling of Fundamental Frequency contour for Thai TonesSuphattharachai ChomphanProblem statement: In Thai, tone is an essential feature of a prosodic syllable to identify the meanings of that syllable or that part of word. To generate the tonal speech with natural prosody, it is needed to manage the fundamental frequency (F0) of the speech appropriately. A successful approach of structural modeling from Mandarin Chinese has been adapted to model … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 7,127 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Environmental Noises on Fundamental Frequency Contours of Thai Expressive SpeechSuphattharachai Chomphan, Chutarat ChompunthProblem statement: The expressive speech of Thai had been studied for a short period of time. An important feature of speech was fundamental frequency (F0) which defines the human speech prosody. It could be used to distinguish the difference between several types of expressive speech. The environmental noises affect the F0 contour for Thai dialects as concluded in the previous … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 6,909 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Control of Fundamental Frequency Contour for Hidden Markov Model-Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: In the conventional HMM-based speech synthesis system for Thai, there is no control of fundamental frequency control in the synthesis stage. The tone correctness of the synthesized speech is unacceptable due to the imbalance of training data of all tones. Approach: This study proposes a mathematical model to control the F0 contour of the synthesized speech. This control … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,057 accessesView PDFCite
Literature ReviewOpen accessEvery word in the titleFundamental Questions about γδT CellsMoulay Yassine Belghali, Saadia Ba-M’hamed, Mouna Khouchani, Brahim AdmouγδT cells is a minor subgroup of T lymphocytes expressing γδ-T Cell Receptor (TCR), with many subsets, dominated by Vδ2 and Vδ1. γδT cells recognize antigens independently of the context of MHC class I, MHC class II, or CD1 presenting molecules. However, this recognition requires the expression of the transmembrane Butyrophilin proteins by the presenting cells. Their activation is controlled … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 15 Dec 2020 · 6,384 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleConversion of Carbon Dioxide: Opportunities and Fundamental ChallengesSajeda A. Al-Saydeh, Syed J. Zaidi, Muftah H. El-NaasThe rising atmospheric levels of carbon dioxide is one of the most urgent challenges facing societies nowadays. There is also great potential in energy carriers and other materials from CO2, with many challenges to overcome. The way to reduce greenhouse gas emissions should be using carbon free sources that do not generate carbon dioxide to the atmosphere. This article reviews … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 17 Jan 2018 · 7,637 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePossible Physical Determination of the Mass, Size, Doubling Time and Density of the Unicellular Organisms Based on the Fundamental Physical ConstantsAtanas Todorov AtanasovIn manuscript the hypothesis 'that the mass, size, doubling time and density of the unicellular organisms (Prokaryotes and Eukaryotes) are determined by the gravitational constant (G, N·m2/kg2), Planck constant (h, J·s) and growth rate vgr (m/s)' is investigated. By scaling analyses it is indicated that the growth rate of the unicellular organisms ranges in a narrow window of 1.0×10-11–1.0×10-10 m/s, … …Physics International, Vol. 7, Issue 2 · 20 Nov 2016 · 8,256 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFundamental Elements to Produce Sesame Yoghurt from Sesame MilkIbrahim Afaneh, Khaled Abu-Alruz, Jihad M. Quasem et al.Problem statement: In previous work sesame milk was developed. The developed milk had slightly acceptable flavor and limited shelf life. Fermentation of sesame milk is one way to overcome these problems. Approach: Sesame yoghurt experiments were carried out using pasteurized sesame milk (75°C for 5 min) with 14% initial sesame seed concentration and 2.7% glucose with different dairy products: lactose, … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 23 Sep 2011 · 8,716 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFundamental Properties of the Galois CorrespondenceAyinde S. Olukayode, Oyekan E. AbiodunProblem Statement: Let K is the splitting field of a polynomial f(x) over a field F and αn be the roots of f in K. Let G be embedded as a subgroup of the symmetric group ς. We determined the Galois group G, and the subgroup. Approach: computed some auxiliary polynomials that had roots in K, where the permutation of … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,296 accessesView PDFCite
Research NotesOpen accessIn the keywordsA Note on a New Method of Investigation of Solutions of Boundary Value Problems for the Elliptic Type Equations of the First OrderNihan A. Aliyev, Alexander A. Katz, Metanet B. MursalovaThe paper deals with investigation of the solutions of the boundary value problem for the Cauchy-Riemann equation on the curvelinear strip in the real plane. Here the boundary conditions are in the special type and are fundamental with respect to the direction solutions are used. An analytic form of the solution of considered boundary value problem is obtained. …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 17 Jan 2018 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDerivation of Potentially Important Masses for Physics and Astrophysics by Dimensional AnalysisDimitar ValevThe Hubble constant has been added in addition to the three fundamental constants (speed of light, gravitational constant and Planck constant) used by Max Planck, for derivation of the Planck mass by dimensional analysis. As a result, a general solution is found for the mass dimension expression m = γp m0, where m0 ≡ mp is the Planck mass, γ … …Physics International, Vol. 8, Issue 1 · 25 Oct 2017 · 9,141 accessesView PDFCite
