Subthreshold VO2 vertical switches for large-bandwidth millimeter-wave and sub-terahertz detection
Mihai Adrian Ionescu, Ali Gilani, Daesung Park, Fatemeh Qaderi Rahaqi
n-linear impedance characteristics of VO2 offer solutions to highly sensitive radio-frequency (RF), millimeterwave (mm-wave), and terahertz (THz) detectors. We demonstrate high-speed broadband sensibility of miniaturized VO2 switches by utilizing the nonli ...
IEEE2022A Bayesian Bandit Approach to Adaptive Delay-based Congestion Control
Pascal Frossard, Stefano D'Aronco
Adapting the transmission rate of video telephony Internet applications in order to guarantee the maximal communication quality is still an open and extremely challenging problem. The congestion control algorithm, which is the algorithm responsible for adj ...

Idiap2016Objective Speech Intelligibility Assessment through Comparison of Phoneme Class Conditional Probability Sequences
Hervé Bourlard, Raphaël Marc Ullmann
Assessment of speech intelligibility is important for the development of speech systems, such as telephony systems and text-to-speech (TTS) systems. Existing approaches to the automatic assessment of intelligibility in telephony typically compare a referen ...
2015Tunable Capacitors and Microwave Filters Based on Vanadium Dioxide Metal-Insulator Transition
Mihai Adrian Ionescu, Clara-Fausta Moldovan, Josef Andreas Schuler, Montserrat Fernandez-Bolanos Badia, Wolfgang Amadeus Vitale, Antonio Paone
We report the fabrication, modeling and characterization of novel microwave tunable capacitors based on the metal-insulator transition (MIT) of Vanadium Dioxide (VO2). We present the advantages of VO2-based capacitors over alternative technologies for micr ...
