Research ArticleOpen accessIn the abstractEvaluation on Score Reliability for Biometric Speaker Authentication SystemsDzati Athiar Ramli, Haryati Jaafar, Muhammad Hazim HasanProblem statement: Fusion weight tuning based on score reliability is imperative in order to ensure the performances of multibiometric systems are sustained. Approach: In this study, two variant of conditions i.e., different performances of individual subsystems and inconsistent quality of test samples are experimented to multibiometric systems. By applying multialgorithm scheme, two types of features extraction method i.e., Linear Predictive … …Journal of Computer Science, Vol. 8, Issue 9 · 16 Aug 2012 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeech Compression of Thai Dialects with Low-Bit-Rate Speech CodersSuphattharachai ChomphanProblem statement: In modern speech communication at low bit rate, speech coding deteriorates the characteristics of the coded speech significantly. Considering the dialects in Thai, the coding quality of four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions has not been studied. Approach: This study presents a comparative study of … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 14 Jul 2012 · 6,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Robust Dynamic Controller, Model Predictive Control BasedMohamed Adel Sellami, Elyes Maherzi, Mongi BesbesProblem statement: More advanced control techniques have been developed in recent decades following the great progress of calculations means. Without considering the constraints on system variables, the response of controlled system moves away from the desired response. Hence the control strategy must provide the ability to integrate these constraints in the design phase of the controller. Approach: This study presents … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 16 Mar 2012 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractCross Validation Evaluation for Breast Cancer Prediction Using Multilayer Perceptron Neural NetworksShirin A. Mojarad, Satnam S. Dlay, Wai L. Woo, Gajanan V. SherbetProblem statement: The presence of metastasis in the regional lymph nodes is the most important factor in predicting prognosis in breast cancer. Many biomarkers have been identified that appear to relate to the aggressive behaviour of cancer. However, the nonlinear relation of these markers to nodal status and also the existence of complex interaction between markers have prohibited an accurate … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 20 Feb 2012 · 7,699 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Study of High Pitch Delay Resolution Technique for Tonal Speech CodingSuphattharachai Chomphan, Chutarat ChompunthProblem statement: In tonal-language speech, since tone plays important role not only on the naturalness and also the intelligibility of the speech, it must be treated appropriately in a speech coder algorithm. Approach: This study proposes an analytical study of the technique of High Pitch Delay Resolutions (HPDR) applied to the adaptive codebook of core coder of Multi-Pulse based Code … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 23 Jan 2012 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractBitrate Scalability for Multi-Pulse Based Code Excited Linear Prediction Speech CoderSuphattharachai Chomphan, Chutarat ChompunthProblem statement: The bitrate scalability is an important functionality that is defined in the Moving Picture Expert Group (MPEG-4) requirements. Since the traffic in a communication network varies with time, the capability of varying the bitrate of a speech coder is needed. Approach: This study proposes an approach to vary the bitrate by using a bitrate scalable tool which is … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 14 Jan 2012 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeech Compression for Noise-Corrupted Thai DialectsSuphattharachai ChomphanProblem statement: Dialects of Thai are quite different in the speaking styles. Environmental noises play an important role in corrupting the communication speech quality. Two factors affect the coded speech in the present speech communication. It is necessary to investigate how the two factors influence on the speech compression. Approach: In this study, the Multi-Pulse based Code Excited Linear Predictive … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 9 Jan 2012 · 7,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractWhy the Dogs of the Dow Bark Loudly in ChinaCarol Wang, James E. Larsen, Fall M. Ainina et al.Problem statement: The Dogs of the Dow (Dow Dogs) strategy, which has gained widespread popularity in the U.S., is found to be considerably successful in China’s stock markets. This trading strategy contradicts the well-established efficient market hypothesis. Approach: This study examines the cross-sectional variations in the magnitude of the predictive power of the Dow Dogs strategy using Chinese stocks for … …American Journal of Economics and Business Administration, Vol. 3, Issue 3 · 4 Nov 2011 · 8,019 accessesView PDFCite
Research ArticleOpen accessIn the abstractIs Wright Test an Appropriate Screening Test for Diagnosis of Brucellosis?Behzad Mohsenpour, Shahla Afrasiabian, Katayoon Hajibagheri, Ebrahim GhaderiProblem statement: Diagnosis of brucellosis is generally based on culture, polymerase chain reaction and serology. The first two methods are not accessible in all parts of world and are expensive. The routine method for diagnosis of brucellosis is considering Wright test as the first screening test; if the results are Wright positive’ Wright would be the next choice otherwise 2ME … …American Journal of Infectious Diseases, Vol. 7, Issue 2 · 17 Sep 2011 · 16,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Adaptive Predictive Control to a Newborn IncubatorMed Aymen Zermani, Elyes Feki, Abdelkader MamiProblem statement: This study presents an application of Indirect Adaptive Generalized Predictive Control (IAGPC) of an incubator for newborn, in order to improve the performance of temperature control. Approach: Analysis of physical phenomena of incubator was involved together knowledge of the dynamic behavior. Incubator was identified by means of Recursive Least Square (RLS) technique associated with a projection of the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,242 accessesView PDFCite
