Adaptive and robust media streaming over multiple channels with bursty losses

Pascal Frossard, Jean-Paul Wagner

This paper addresses the problem of efficiently delivering a layered media stream from multiple senders to a single receiver, over channels that present correlated packet loss patterns. Using a digital fountain approach, the performance of a distributed st ...

High Speed Flow Visualisation of an Impinging Jet on a Pelton Turbine Bucket

François Avellan, Mohamed Farhat, Alexandre Perrig

This paper deals with flow investigations using endoscopes in a single-injector reduced scale Pelton turbine performed with a CMOS high-speed camera. Both onboard and external visualizations techniques of the flow in a bucket are presented. The flow observ ...

Hydrodynamics of the free surface flow in Pelton turbine buckets

Alexandre Perrig

The design of Pelton turbines has always been more difficult than that of reaction turbines, and their performances lower. Indeed, the Pelton turbines combine 4 types of flows: (i) confined, steady-state flow in the piping systems and injector, (ii) free w ...

Tradeoffs in Design of Low-Power Gated-Oscillator CDR Circuits

Yusuf Leblebici, Seyed Armin Tajalli, Paul Victor Georges Muller

This article describes some techniques for implementing low- power clock and data recovery (CDR) circuits based on gated- oscillator (GO) topology for short distance applications. Here, the main tradeoffs in design of a high performance and power-efficient ...

Analysis and modeling of jitter and frequency tolerance in gated oscillator based CDRs

Yusuf Leblebici, Seyed Armin Tajalli, Paul Victor Georges Muller

This paper presents an approach for analyzing and modeling of gated-oscillator (GO) -based CDRs and predicting their performance aspects such as jitter tolerance (JTOL) and frequency tolerance (FTOL). It is shown that high JTOL of this topology in addition ...
