VPP: Privacy Preserving Machine Learning via Undervolting

Md Shohidul Islam, Behnam Omidi, Ihsen Alouani, Khaled Khasawneh

Machine Learning (ML) systems are susceptible to membership inference attacks (MIAs), which leak private information from the training data. Specifically, MIAs are able to infer whether a target sample has been used in the training data of a given model. Such privacy breaching concern motivated…

Subsonic cavity flow control with Micro-Magneto-Mechanical Systems (MMMS) microvalves

Thomas Arnoult, Colin Leclercq, Cécile Ghouila-Houri, A. Mazzamurro, R. Viard, Eric Garnier, C. Poussot-Vassal, A. Merlen, Denis Sipp, Philippe Pernod, Abdelkrim Talbi

Flow control consists in modifying a flow natural state in order to converge towards another state which is considered as favorable, as drag or noise radiation might be reduced. In this paper, open-loop flow control experiments are carried out on a subsonic open-cavity flow. In the case of unstable…

Relation between thermal quenching of photoluminescence and negative capacitance on InGaN/GaN multiple quantum wells in p-i-n structure

Orhan Özdemir, Hanife Baş, Neslihan Ayarcı Kuruoğlu, Kutsal Bozkurt, Mustafa Aydın, Fahrettin Sarcan, Ayşe Erol, Bandar Alshehri, Karim Dogheche, El Hadj Dogheche

Temperature-dependent photoluminescence (PL) and surface photovoltage (SPV) measurements were carried out to detect radiative and non-radiative transitions on InGaN/GaN quantum well (QW) blue light-emitting device (LED). The emissions, peaking at 3.03 eV and 2.89 eV, were present in both PL and SPV…

Investigation of Current Collapse Mechanism on AlGaN/GaN Power Diodes

Martin Doublet, N. Defrance, Etienne Okada, Loris Pace, Thierry Duquesne, Bouyssou Emilien, Arnaud Yvon, Nadir Idir, Jean-Claude de Jaeger

In this paper, a methodology is proposed for studying the current collapse effects of Gallium Nitride (GaN) power diodes and the consequences on the dynamic on-resistance (RON). Indeed, the growing interest of GaN based, high frequency power conversion requires an accurate characterization and a…

Design and fabrication of an inverted hat antenna paired with a filled cavity for radio-navigation applications

Z. Hamouda, S. Azaizia, M. Hideche, A. Zemmam, T. Lasri

Antennas installed on aircraft are used for communications as well as for various radio navigation systems such as direction finders, distance measuring systems, and altimeters. Generally, these systems use blade antennas operating in the L frequency band. Recently, inverted-hat empty section…

Effect of different separation frequencies of the two-tone input signal on the output power of GaN on SiC HEMT

Mohammad Abdul Alim, Mayahsa Ali, Christophe Gaquière

This research aims to determine whether a GaN HEMT device made on SiC substrate has a memory effect. To accomplish this, the intermodulation distortion technique with the separation frequency (Δf) of the two-tone input signals was applied at three different frequency levels, one at f1 = 53 MHz and…

A novel cloud approach for connected vehicles

Geoffrey Wilhelm, Marwane Ayaida, Hacène Fouchal

Cooperative intelligent transport systems (C-ITSs) are being deployed all around the world. Shortly, in addition to vehicles, bicycles, pedestrians, buses, and all moving equipment will be compatible with C-ITS. These systems are connected through wireless local area networks based on WIFI IEEE 802…

Friction dynamics of elasto-inertial turbulence in Taylor–Couette flow of viscoelastic fluids

Masoud Moazzen, Tom Lacassagne, Vincent Thomy, S. Amir Bahrani

Dynamic properties of elasto-inertial turbulence (EIT) are studied in a Taylor–Couette geometry. EIT is a chaotic flow state that develops upon both non-negligible inertia and viscoelasticity. A combination of direct flow visualization and torque measurement allows to verify the earlier onset of…

Performance improvement with non-alloyed ohmic contacts technology on AlGaN/GaN High Electron Mobility Transistors on 6H-SiC substrate

Marie Lesecq, Yassine Fouzi, Ali Abboud, N. Defrance, Francois Vaurette, Saliha Ouendi, Etienne Okada, Marc Portail, Micka Bah, Daniel Alquier, Jean-Claude de Jaeger, Eric Frayssinet, Yvon Cordier

In this paper, non-alloyed ohmic contacts regrown by molecular beam epitaxy (MBE) are fabricated on AlGaN/ GaN high-electron-mobility transistors on 6H-SiC substrate. Low ohmic contact resistance of 0.13 Ω.mm is obtained. This paper demonstrates the high frequency and high power performance…

Development of nanomaterial enabling highly sensitive SALDI‐MS peptide analysis

Aline Cournut, Ioana Silvia Hosu, Flavie Braud, Paul Moustiez, Yannick Coffinier, Christine Enjalbal, Claudia Bich

RationaleSALDI-MS (Surface-Assisted Laser Desorption/Ionisation Mass Spectrometry) is an approach derived from MALDI-MS (Matrix-Assisted Laser Desorption/Ionisation) which overcomes the drawbacks associated with the use of organic matrices required to co-crystallize with the analytes. Indeed,…
