P2P live scalable video streaming with ALTO service
(2012-10)It has been measured that, as high as 80% of the average Internet traffic is now from peer-to-peer (P2P) applications, and upwards of 90% during peak hours. These results tell us that a significant portion of the traffic ... -
Parkinson’s disease diagnosis using machine learning and voice
(IEEE, 2018)Biomarkers derived from human voice can offer in-sight into neurological disorders, such as Parkinson's disease (PD), because of their underlying cognitive and neuromuscular function. PD is a progressive neurodegenerative ... -
