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 ...

Internet advertising to recruit respondents for a web-based survey on the mobility of teenagers. Effectiveness in five European countries

Emmanuel Pierre Jean Ravalet, Antoine Lohou

To study mobility behaviours and images of transport modes of teenagers in Europe, we organized a web-based survey in 2016. The population concerned is composed of teenagers (14-17 years old) living in five European countries (France, Germany, Great-Britai ...

Utilisation d'un excitateur électrodynamique en mode capteur/actionneur et ses applications en vibro-acoustique

Romain Boulandet, Philippe Herzog

L’analyse des principaux modes vibratoires d’une structure mince, et notamment de ses caractéristiques de mobilité, permettent de prédire son comportement dynamique lorsqu’elle est soumise à une excitation mécanique ou acoustique, et de définir un contrôle ...

Explanatory Variables for per Capita Stocks and Flows of Copper and Zinc

Claudia Rebeca Binder Signer

A number of potential explanatory variables for the stocks and flows of copper and zinc in contemporary technological societies are co-analyzed with the tools of exploratory data analysis. A one-year analysis (circa 1994) is performed for 50 countries that ...

Modulation Frequency Features For Phoneme Recognition In Noisy Speech

Hynek Hermansky, Sriram Ganapathy, Samuel Thomas

In this letter, a new feature extraction technique based on modulation spectrum derived from syllable-length segments of sub-band temporal envelopes is proposed. These sub-band envelopes are derived from auto-regressive modelling of Hilbert envelopes of th ...

Hilbert Envelope Based Spectro-Temporal Features for Phoneme Recognition in Telephone Speech

Hynek Hermansky, Sriram Ganapathy, Samuel Thomas

In this paper, we present a spectro-temporal feature extraction technique using sub-band Hilbert envelopes of relatively long segments of speech signal. Hilbert envelopes of the sub-bands are estimated using Frequency Domain Linear Prediction (FDLP). Spect ...
