Research ArticleOpen accessIn the keywordsStudents’ Voices about Learning with TechnologyRuth Geer, Trudy-Ann SweeneyProblem statement: This study argues for the inclusion of student voice as a valid means of identifying 21st century pedagogical approaches to learning. Today’s students are increasingly living and thriving in a digital world and have a new “digital vernacular” which leads to differences in the way students think about learning. Approach: In Australia many students are already immersed in … …Journal of Social Sciences, Vol. 8, Issue 2 · 26 Mar 2012 · 11,679 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMultipath Adaptive Packet Dispersion for Voice ApplicationsJ. Faritha Banu, V. RamachandranProblem statement: The quality of Voice over IP applications is decided by the main factors like network capacity and technologies such as codec type, Packet Loss Concealment (PLC) and Forward Error Correction (FEC). Approach: In MPLS networks multiple Label Switched Paths (LSP) are established between MPLS ingress and egress nodes to enhance the network performance and QoS for subscribers. To … …Journal of Computer Science, Vol. 8, Issue 4 · 27 Jan 2012 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecognition of Pathological Voices by Human Factor Cepstral Coefficients (HFCC)Rabeh Hamdi, Salah Hajji, Adnene CherifHuman speech is a means of communication that is very important in our daily lives. It is characterized by its great ability to transmit our ideas, our emotions, our personality etc. So, any alteration of the voice can prevent the person from exercising his professional and daily life naturally. It is for these reasons that it is very necessary to … …Journal of Computer Science, Vol. 16, Issue 8 · 7 Aug 2020 · 6,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Approach to the Performance and Efficiency Power Analysis on Embedded Devices Using AsteriskAdauto Cavalcante Menezes, Toniclay Andrade Nogueira, Edward David Moreno Ordonez, Admilson de Ribamar Lima RibeiroVoice over IP (VoIP) communication will dominate the computing world for years to come. In order to perform VoIP communication, it is necessary to encode and decode the voice. This process consumes the main computational resources, as an example, it is possible to mention the processor and memory. The telecommunication industries provide equipment with high purchasing prices, which makes the … …Journal of Computer Science, Vol. 14, Issue 7 · 2 Aug 2018 · 8,258 accessesView PDFCite
