The focus of this work is on the estimation of quality of service (QoS) parameters seen by an application. Our proposal is based on end-to-end active measurements and statistical learning tools. We propose a methodology where the system is trained during short periods with application flows and probe packets bursts. We learn the relation between QoS parameters seen by the application and the st...

A novel instrumented baffle surrounding the suspended end mirror in input mode cleaner cavity of Virgo interferometer was installed Spring 2021. Since then, device has been regularly operated experiment, and data collected show good stability. The will operate upcoming O4 observation run, serving as a demonstrator technology designed to instrument baffles front main mirrors time for O5. In this...

We present an end-to-end approach to generalize the classical theory of R-D optimized mode selection for point-to-point video communication. We introduce a. notion of global distortion by taking into consideration of both the path characteristics and the receiver behavior, in addition to the source behavior. We derive, for the first time, a set of accurate global distortion metrics for any pack...

– The software-defined-radio concept received increasing attention due to necessity of multi-mode/multi-system capable terminals for next generation communication systems. This paper summarizes the requirements of a multi-mode compliant digital-front-end (DFE) and describes concepts for cellular terminal implementations on silicon. A partitioning is proposed wherein functionality, normally loca...
