We investigated whether differences in formants and their bandwidths, previously reported comparing small sample population of healthy individuals and patients with obstructive sleep apnea (OSA), are detected on a larger population representative of a clinical practice scenario. We examine possible indirect or mediated effects of clinical variables, which may shed some light on the connection between...
Online gaming connects players from all over the world together for fun and entertainment, and has been regarded as one of the most profitable and popular Internet services. Besides, there is a growing trend towards moving local applications to remote data centers: this is often referred to as the cloud. With the purpose of studying the impact of Cloud Gaming on the access network load, in this paper...
So far latency has been regarded as a minor issue in Passive Optical Networks (PONs). However it may become a key factor for the commercial success of PON and WDM-PON. In this work we review the relevance of very-low latency in the access as the enabler of new higly-interactive cloud services. Then, we propose an approach for delay-based differentiation in PON that causes the delay variance to become...
This article describes the architecture of two broadband satellite communication systems using a very small aperture terminal which have been installed on two Spanish oceanographic research vessels. The potential use, equipment and their characteristics are studied and compared. Analysing four parameters (jitter, round time trip, package loss and throughput), system configuration has been modified...
One of the main drawbacks of ultrasonic transducers is the difficulty to determine the bearing angle of echoes coming from an obstacle placed in front. Echoes often provide only the distance to the reflector inside the emission cone of the transducer, so some applications associate several transducers with the same scanning area to obtain more information about the common reflectors. This work proposes...
