Planar Micro-thermoelectric Generators Based on Cu55Ni45 and Ni90Cr10 Thermocouples for IoT Applications

Ibrahim Bel-Hadj, Zahia Bougrioua, K. Ziouche

In this work, we present our novel planar micro-thermoelectric generators (µTEGs) integrating an original “folded” thermopile topology, periodically distributed on suspended membranes. The thermopile integrates eco-friendly and low-cost materials as Constantan (Cu55Ni45) and Chromel (Ni90Cr10) that...

CNR-IEMN-CD and CNR-IEMN-CSD Approaches for Covid-19 Detection and Covid-19 Severity Detection from 3D CT-scans

Fares Bougourzi, Cosimo Distante, Fadi Dornaika, Abdelmalik Taleb-Ahmed

Since its appearance in late 2019, Covid-19 has become an active research topic for the artificial intelligence (AI) community. One of the most interesting AI topics is Covid-19 analysis from medical imaging. CT-scan imaging is the most informative tool about this disease.This work is part of the...

Detachment of immersed microparticles and the collective dynamics of microspheres in evaporating droplets, Décrochement de microparticules immergées et dynamique collective de microsphères dans une goutte en évaporation

Anna Ipatova

Dirts or microparticles are usually small enough to be invisible to the naked eye, but their effects may be substantial in our daily life. For instance, their presence is often undesirable in various domains such as in food industries where they may act as polluting agents or in microelectronics..., Les objets micrométriques sont généralement suffisamment petits pour qu'on puisse les distinguer à l'œil nu, mais leurs effets indésirables peuvent être majeurs dans notre vie quotidienne. Par exemple, dans l'industrie agroalimentaire, des bactéries micrométriques sont une source de...

Deep Learning Solution for Quantification of Fluorescence Particles on a Membrane

Abdellah Zakaria Sellam, Azeddine Benlamoudi, Clément Antoine Cid, Leopold Dobelle, Amina Slama, Yassin El Hillali, Abdelmalik Taleb-Ahmed

The detection and quantification of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) virus particles in ambient waters using a membrane-based in-gel loop-mediated isothermal amplification (mgLAMP) method can play an important role in large-scale environmental surveillance for early...

Multifractal analysis for improved osteoporosis classification

Ouardia Bouzeboudja, Boualem Haddad, Abdelmalik Taleb-Ahmed, Soltane Ameur, Mohammed El Hassouni, Rachid Jennane

Osteoporosis is characterized by decrease of bone mineral density and alterations of the bone microarchitecture, leading to bone fragility and an increased risk of fractures. Discrimination between osteoporotic and healthy subjects using X-ray images presents a major challenge for medical image...

Visual soft landing of an autonomous quadrotor on a moving pad using a combined fuzzy velocity control with model predictive control

Oussama Bouaiss, Raihane Mechgoug, Abdelmalik Taleb-Ahmed

Autonomous landing is a vital option for Unmanned Aerial vehicles (UAV), as it can be a fail-safe in many critical cases. This paper demonstrates a complete solution for the soft landing application of a fully autonomous quadrotor on a moving pad considering external disturbance, model...

Bound states in the continuum in circular clusters of scatterers

Marc Martí-Sabaté, Bahram Djafari-Rouhani, Daniel Torrent

ABSTRACTIn this work we study the localization of flexural waves in highly symmetric clusters of scatterers. It is shown that when the scatterers are placed regularly in the perimeter of a circumference, the quality factor of the resonances strongly increases with the number of scatterers in the...

Modeling and control of conducting polymer actuator

Lingxiao Xun, Gang Zheng, Sofiane Ghenna, Alexandre Kruszewski, Eric Cattan, Christian Duriez, Sebastien Grondel

Conducting polymer (CP) actuator has nonlinear dynamic characteristics during its charge process. In this study, we proposed an electromechanic model and an optimal controller for a type of ionic electroactive polymer (IEPA) actuator with submillimeter scale, which can produce large deformation...

Design and experimental analysis of a high force piezoelectric linear motor

Sofiane Ghenna, Yves Bernard, Laurent Daniel

In this paper, the design and experimental analysis of a piezo-motor for applications requiring compact size, high blocking and driving forces are presented. Mechanical design addresses difficulties associated with high integration flexibility and high blocking force for the motor. The technology...
