Research ArticleOpen accessAll words, across the recordEffects of Noises on the Analysis of Fundamental Frequency Contours for Thai SpeechSuphattharachai ChomphanProblem statement: In speech communication, noises from surrounding environments affect the communication quality with various aspects. The received speech quality should be analyzed to see how the important noises reduce the speech quality so that we can eliminate them in an appropriate way. Approach: This study presents a study on the analysis of the noise effects on Thai speech. Four … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 6,833 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHighly-Available, Collaborative, Trainable Communication – a Policy – Neutral ApproachChristian Schreibaumer, Isabella Stein, Eberhard DobermannScalable theory have led to many advances. Data flow is constantly growing and systems are expanding. Theoretical principles of red-black trees can help to build a scalable system, where data easily can expand and in the end energy is saved. We propose a novel solution, an organizational platform, an algorithm for the analysis of agents, which we call Mop. With … …Journal of Computer Science, Vol. 14, Issue 6 · 5 Apr 2018 · 9,778 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCongestion Free Routing in Adhoc NetworksT. Senthil Kumaran, V. SankaranarayananProblem statement: A Mobile Ad-Hoc Network (MANET) is a temporary network; the mobile devices in an ad-hoc network are communicating through wireless links without any pre-existing infrastructure. The one major problem of this network is network congestion, it may take place at any intermediate nodes when data packets are traveling from source to destination.
