Research ArticleOpen accessAll words, across the recordAutonomous Online Predictive Monitoring System for Hazardous Air Pollution Prediction: A Case StudyAyed A. Salman, Fawaz S. Al-AnziEnvironment is increasingly becoming an important issue in the world of politics and global economy as well as people's life. Environmental deterioration resulted from human activity; misuse of natural resources. Pollution is now a global issue that ecologically, economically and politically requires imminent, intelligent and global solutions. This paper present findings and results of a real project, supported by the … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 31 May 2016 · 7,529 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Comparison of Spatio-Temporal Bayesian Models for Reconstruction of Rainfall Fields in a Cloud Seeding ExperimentSujit k. sahu, Giovanna Jona Lasinio, Arianna orasi, Kanti V. MardiaIn response to the drought experienced in Southern Italy a rain seeding project has been setup and developed during the years 1989-1994. The initiative was taken with the purpose of applying existing methods of rain enhancement technology to regions of south Italy including Puglia. The aim of this study is to provide statistical support for the evaluation of the experimental … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,813 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThai Expressive Speech Processing Technology: A ReviewSuphattharachai ChomphanProblem statement: The studies on Thai expressive speech or emotional speech have been conducted for years. Most of them are expected to analysis the characteristics of Thai expressive speech. However, the conclusive reviews on these studies have not been conducted for further study on the speech technology or application of Thai expressive speech. Approach: The review of research on Thai … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 12 Jan 2012 · 6,736 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSpeech Compression for Noise-Corrupted Thai Expressive SpeechSuphattharachai ChomphanProblem statement: In speech communication, speech coding aims at preserving the speech quality with lower coding bitrate. When considering the communication environment, various types of noises deteriorates the speech quality. The expressive speech with different speaking styles may cause different speech quality with the same coding method. Approach: This research proposed a study of speech compression for noise-corrupted Thai expressive … …Journal of Computer Science, Vol. 7, Issue 10 · 6 Aug 2011 · 6,231 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAnalysis of Fundamental Frequency Contour of Coded Speech Based on Multi-Pulse Based Code Excited Linear Prediction AlgorithmSuphattharachai ChomphanProblem statement: In low-bit-rate speech communication, speech coding deteriorates the characteristics of the coded speech significantly. An important feature of the speech is the fundamental frequency contour which determines the pitch information of the speech. It has been known that pitch information is one of the core parameter of the multi-pulse based code excited linear prediction (MPCELP) speech coder. Therefore … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,463 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordMulti-Pulse Based Code Excited Linear Predictive Speech Coder with Fine Granularity Scalability for Tonal LanguageSuphattharachai ChomphanProblem statement: The flexible bit-rate speech coder plays an important role in the modern speech communication. The MP-CELP speech coder which is a candidate of the MPEG4 natural speech coder supports a flexible and wide bit-rate range. However, a fine scalability had not been included. To support finer scalability of the coding rate, it had been studied in this study. … …Journal of Computer Science, Vol. 6, Issue 11 · 24 Nov 2010 · 7,194 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPerformance Evaluation of Multi-Pulse Based Code Excited Linear Predictive Speech Coder with Bitrate Scalable Tool over Additive White Gaussian Noise and Rayleigh Fading ChannelsSuphattharachai ChomphanProblem statement: In the modern speech communication technology, the speech coding with bitrate scalability was needed. However, various types of noises in the communication channels cause damages in the transmitted information especially speech data. Tonal-language speech was also affected by this situation. Approach: Based on the high pitch delay resolution technique, the MPCELP speech coding was proposed over the environment … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,090 accessesView PDF Cite
