QxLab has two papers at the Irish Signals and Systems Conference in Maynooth University today. MSc student, Tong Mo presented work of speech Quality of Experience. Her research investigated how computer models for speech quality prediction in systems such as Skype or Google Hangouts. She developed an algorithm to minimise errors in the presence of jitter buffers.
A second paper was presented by PhD candidate Hamed Jahromi entitled, “Establishing Waiting Time Thresholds in Interactive Web Mapping Applications for Network QoE Management.” Hamed’s work looked at the perception of time in web applications. Is an additional delay of half a second noticeable if you have already waited 5 seconds for a Google Map page to load? Time is not absolute and Hamed wants to understand the impact of delays on web applications in order to optimise network resources for interactive applications other than speech and video streaming. This work was co-authored with Delcan T. Delaney from UCD Engineering and Brendan Rooney from UCD Psychology.
This research was sponsored by UCD School of Computer Science and the SFI CONNECT Centre for Future Networks.
