Research ArticleOpen accessIn the keywordsExtraction of Arabic Standard MicromelodyA. Chentir, M. Guerti, D. J. HirstProblem statement: In the early days of speech synthesis research the obvious focus of attention was intelligibility. But many researchers agree that the major remaining obstacle to fully acceptable synthetic speech is that it continues to be insufficiently natural. Approach: In this study, we exploited microvariations of fundamental frequency (F0) of speech (intrinsic and co-intrinsic effects) to extract micromelody effect … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,291 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Bipolar Cockcroft-Walton Voltage Multiplier for Gas LasersShahid Iqbal, Rosli BesarA bipolar Cockcroft-Walton voltage multiplier (CWVM) is proposed as an attractive alternative to the symmetrical Cockcroft-Walton voltage multiplier for continuous wave gas lasers (e.g. carbon dioxide gas laser). The proposed CWVM formed by combining positive and negative voltage multipliers consisting of equal number of stages and driving in parallel by an ac voltage source. The proposed voltage multiplier needs only … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,274 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Empirical Study on E-Learning versus Traditional Learning among Electronics Engineering StudentsWai Kit Wong, Poh Kiat NgIn academia, it appears that many lecturers are still contented in using traditional lecturing methods. Cultivating the use of e-learning requires proper understanding of its difference with traditional learning. In this study, the difference between e-learning with traditional learning was descriptively and empirically investigated, with an emphasis on a module in Electronics Engineering known as Fundamentals of Operational Amplifier. This … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 27 Jun 2016 · 8,270 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn The Diophantine Equation xa + ya = pkzbKeng Yarn Wong, Hailiza KamarulhailiIn this study, we consider the Diophantine equation xa + ya = pkzb where p is a prime number, gcd(a, b) = 1 and k,a,b∈Z+. We solve this equation parametrically by considering different cases of x and y and find that there exist infinitely many nontrivial integer solutions, where the formulated parametric solutions solve xa + ya = pkzb completely … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 11 Mar 2017 · 7,295 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComputational Techniques for Stability Analysis of a Class of Dynamic Economic ModelsGeorge E. Halkos, Kyriaki D. TsilikaModern microeconomics and macroeconomics study dynamic phenomena. Dynamics could predict future states of an economy based on its structural characteristics. Dynamic models in discrete time discrete state economic systems may take the form of one single linear difference equation or a system of linear difference equations. In this study we use Xcas and Mathematica as software tools in order to … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 12 Dec 2012 · 7,388 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Importance of Numbers and the Need to Study Primes: The Prime QuestionsMatthew Curtis, Gurudeo A. TularamProblem statement: The study of prime numbers is important today as it was in ancient times. The level of interest in any form of mathematics of students in Australian high schools is decreasing and furthermore the level of interest in number theory is also less that it was before; prime numbers is not being considered as an area of interest … …Journal of Mathematics and Statistics, Vol. 7, Issue 4 · 14 Sep 2011 · 9,665 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLatent Dirichlet Allocation Model for Raga Identification of Carnatic MusicRajeswari Sridhar, Manasa Subramanian, B. M. Lavanya et al.Problem statement: In this study the Raga of South Indian Carnatic music is determined by constructing a model. Raga is a pre-determined arrangement of notes, which is characterized by an Arohana and Avarohana, which is the ascending and descending arrangement of notes and Raga lakshana. Approach: In this study a Latent Dirichlet Allocation (LDA) model is constructed to identify the … …Journal of Computer Science, Vol. 7, Issue 11 · 30 Aug 2011 · 7,741 accessesView PDFCite
Research ArticleOpen accessIn the keywordsKoch Curves: Rewriting System, Geometry and ApplicationMamta Rani, Riaz Ul Haq, Norrozila SulaimanProblem statement: Recently, new Koch curves have been generated by dividing the initiator into three unequal parts. There is no formal rewriting system to generate such kind of curves. Approach: It is required to measure the new changed geometrical properties. Generalized rewriting systems for the new Koch curves have been developed. Results: New formulas have been given to measure their … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,070 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIndividualization Training of Players on Positions at the Level of Handball Junior TeamsPitigoi GabrielProblem statement: Starting from the observation that for the handball players, who finished the junior state in hard to integrate in senior teams due to a low level of preparation. I hypothesized that at this level we can use all organizational forms of individual training (frontal relation, group level, individual).Using individual records, performance behavior characteristics of the players to positions, … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 7,238 accessesView PDFCite
