Flow control techniques can be defined as methods changing a flow natural dynamics. The control of a flow can be achieved with actuators affecting the flow momentum. Therefore, a MMMS microvalve was designed and characterized. The micro-actuators have then been integrated to a wind tunnel on the…

High temperature gradient micro-sensors for skin-friction measurement in flow control applications

Cécile Ghouila-Houri, Manon Benedito, Eric Garnier, Abdelkrim Talbi, Aurélien Mazzamurro, Romain Viard, Alain Merlen, Philippe Pernod, Thomas Arnoult, Quentin Gallas

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were designed and developed for flow separation control. Based on thermal principle, the transducers measure the amplitude and the sign of skin friction, making them particularly useful for flow separation detection. A…

Securing Deep Spiking Neural Networks against Adversarial Attacks through Inherent Structural Parameters

R. El-Allami, A. Marchisio, M. Shafique, Ihsen Alouani

Deep Learning (DL) algorithms have gained popularity owing to their practical problem-solving capacity. However, they suffer from a serious integrity threat, i.e., their vulnerability to adversarial attacks. In the quest for DL trustworthiness, recent works claimed the inherent robustness of…

Energy-efficient 1-bit feedback NOMA in wireless networks with no CSIT/CDIT

Hajar El Hassani, Anne Savard, E Veronica Belmega

In this paper, the energy efficiency of a two-user downlink non-orthogonal multiple access (NOMA) system is investigated. We consider a stochastic time-varying channel that is unknown at the transmitter side (in state and distribution) and propose an online learning method that is energy efficient…

Simultaneous Hydrolysis and Detection of Organophosphate by Benzimidazole Containing Ligand-Based Zinc(II) Complexes

Gaber Mersal, Hamdy El-Sheshtawy, Mohammed Amin, Nasser Mostafa, Amine Mezni, Sarah Alharthi, Rabah Boukherroub, Mohamed Ibrahim

The agricultural use of organophosphorus pesticides is a widespread practice with significant advantages in crop health and product yield. An undesirable consequence is the contamination of soil and groundwater by these neurotoxins resulting from over application and run-off. Here, we design and…

Experimental realization of a pillared metasurface for flexural wave focusing

Wan Wang, Julio Andrés Iglesias Martinez, Yabin Jin, Bahram Djafari-Rouhani, Abdelkrim Khelif

A metasurface is an array of subwavelength units with modulated wave responses that show great potential for the control of refractive/reflective properties in compact functional devices. In this work, we propose an elastic metasurface consisting of a line of pillars with gradient heights, erected…

Joint modeling of received power, mean delay, and delay spread for wideband radio channels

Ayush Bharti, Ramoni Adeogun, Xuesong Cai, Wei Fan, Francois-Xavier Briol, Laurent Clavier, Troels Pedersen

We propose a multivariate log-normal distribution to jointly model received power, mean delay, and root mean square (rms) delay spread of wideband radio channels, referred to as the standardized temporal moments. The model is validated using experimental data collected from five different…
