In this paper, we provide an experimental approach to replace constants with learned contextual functions for Skype - a widely used real-time communication (RTC) application.  ...  We present Resonance, a system based on contextual bandits (CB). We describe experiences from three real-world experiments: applying it to the audio, video, and transport components in Skype.  ...  Discussion This paper introduces Resonance, a system for replacing application constants with context-aware models. We built and deployed this system for the real-time production scenarios of Skype.  ...

Resonances and poles in the second Riemann sheet [article]

Thomas Wolkanowski
2014 arXiv   pre-print
Besides that, we investigate the time evolution of a particle described by such a model.  ...  In this work we study basic properties of unstable particles and scalar hadronic resonances, respectively, within simple quantum mechanical and quantum field theoretical (effective) models.  ...  Besides the branch cut, we need to take the real poles on the first sheet with real renormalization constants into account.  ...

FSK-based Simultaneous Wireless Information and Power Transfer in Inductively Coupled Resonant Circuits Exploiting Frequency Splitting [article]

Peter A. Hoeher
2020 arXiv   pre-print
In the area of power electronics, tracking of one of the peak frequencies is state-of-the-art. In the data transmission community, however, the frequency splitting effect is often ignored.  ...  Inductively coupled resonant circuits are affected by the so-called frequency splitting phenomenon at short distances.  ...  For the purpose of analysis, the inner two-port network of the series-resonant circuit model shown on the left side in Fig. 2 can be replaced by the T-network structure depicted on the right.  ...
