Performance assessment of the adaptive GoP-size extension of the wireless softCast video scheme

Anthony Trioux, François-Xavier Coudoux, Patrick Corlay, M Gharbi

The SoftCast video transmission scheme has been proposed as a promising alternative to traditional video broadcasting systems in wireless error-prone environments. However, in its original form, the scheme may introduce annoying artifacts such as temporal quality variations or the so-called ghost…

Atomic Layer Deposition of a Nanometer-Thick Li₃PO₄ Protective Layer on LiNi_0.5Mn_1.5O₄ Films: Dream or Reality for Long-Term Cycling?

Maxime Hallot, Borja Caja-Munoz, Clement Leviel, Oleg Lebedev, Richard Retoux, José Avila, Pascal Roussel, Maria Carmen Asensio, Christophe Lethien

LiNi0.5Mn1.5O4 (LNMO) is a promising 5V-class electrode for Li-ion batteries but suffers from manganese dissolution and electrolyte decomposition owing to the high working potential. An attractive solution to stabilize the surface chemistry consists in mastering the interface between the LNMO…

Sonification and Animation of Multivariate Data to Illuminate Dynamics of Geyser Eruptions

Anna Barth, Leif Karlstrom, Benjamin Holtzman, Arthur Paté, Avinash Nayak

Abstract Sonification of time series data in natural science has gained increasing attention as an observational and educational tool. Sound is a direct representation for oscillatory data, but for most phenomena, less direct representational methods are necessary. Coupled with animated visual…

Acoustic radiation force on small spheres due to transient acoustic fields

Qing Wang, Antoine Riaud, Jia Zhou, Zhixiong Gong, Michael Baudoin

Acoustic radiation force is a net force experienced by an object under the action of an acoustic wave. Most theoretical models require the acoustic wave to be periodic, if not purely monofrequency, and are therefore irrelevant for the study of acoustic radiation force due to acoustic pulses. Here,…

Defensive approximation: securing CNNs using approximate computing

Amira Guesmi, Ihsen Alouani, Khaled Khasawneh, Mouna Baklouti, Tarek Frikha, Mohamed Abid, Nael Abu-Ghazaleh

In the past few years, an increasing number of machine-learning and deep learning structures, such as Convolutional Neural Networks (CNNs), have been applied to solving a wide range of real-life problems. However, these architectures are vulnerable to adversarial attacks: Inputs crafted carefully…

Influence of ion implantation on the charge storage mechanism of vanadium nitride pseudocapacitive thin films

Etienne Le Calvez, Dmitri Yarekha, Laurent Fugère, Kévin Robert, Marielle Huvé, Maya Marinova, Olivier Crosnier, Christophe Lethien, Thierry Brousse

The influence of microstructural or structural defects is seldom investigated in pseudocapacitive electrodes. Indeed, most of the synthesized materials do present defects at every scales which contribute to the improvement of the charge storage. In this study VN thin films were deposited by…
