A new spectral index for the extraction of built-up land features from Landsat 8 satellite imagery

Rafik Bouhennache, Toufik Bouden, Abdelmalik Taleb-Ahmed, Abbas Cheddad

Extracting built-up areas from remote sensing data like Landsat 8 satellite is a challenge. We have investigated it by proposing a new index referred as built-up land features extraction index (BLFEI). The BLFEI index takes advantage of its simplicity and good separability between the four major…

Développement d'un microsystème étirable pour l'étude de l'activité électrique de cellules neuronales sous contrainte mécanique, Development of a stretchable microsystem for the study of electronic activity of neuronal cells under mechanical strain

Tiffany Baëtens

Alors que 50 million de personnes souffrent de traumatismes crâniens chaque année dans le monde entier, le choc (stress mécanique externe), engendré à cette occasion sur le réseau neuronal, peut amener à l’apparition de lésions cérébrales traumatiques. A moyen et long termes, ce processus peut…, 50 million people suffer from head trauma each year worldwide. The shock (external mechanical stress) acting on neural networks insided the brain can lead to the appearance of traumatic brain injuries (TBI). In the short term and long term, this process can lead to neuroinflammation and the…

Single-electron tunneling PbS/InP neuromorphic computing building blocks

P F Jarschel, J H Kim, Louis Biadala, Maxime Berthe, Yannick Lambert, R M Osgood, G. Patriarche, B. Grandidier, Jimmy Xu

We study single-electron tunneling (SET) characteristics in crystalline PbS/InP junctions, that exhibit single-electron Coulomb-blockade staircases along with memory and memory-fading behaviors. This gives rise to both short-term and long-term plasticities as well as a convenient non-linear…

Optomechanics: a key towards next-generation experiments in atomic force microscopy?

Lucien Schwab, Pierre Allain, Didier Theron, Marc Faucher, Benjamin Walter, Sébastien Hentz, Guillaume Jourdan, Ivan Favero, Bernard Legrand

Atomic Force Microscopy (AFM) is a versatile and ubiquitous technique based on a resonating tip probe that interacts with the sample to be analysed in terms of topography and mechanical properties. Next-generation investigations in molecular biophysics like protein folding/unfolding, receptor-…

Channel correlation-based approach for feedback overhead reduction in massive MIMO

Frédéric Challita, Pierre Laly, Marwan Yusuf, Emmeric Tanghe, Wout Joseph, Pierre Degauque, M. Lienard, Davy Gaillot

For frequency-division duplex multiple-input-multiple-output (MIMO) systems, the channel state information at the transmitter is usually obtained by sending pilots or reference signals from all elements of the antenna array. The channel is then estimated by the receiver and communicated back to the…

Heat treatment of commercial polydimethylsiloxane PDMS precursors: Part II. Thermal properties of carbon-based ceramic nanocomposites

Srisaran Venkatachalam, Stéphane Lenfant, Michael Depriester, Abdelhak Hadj Sahraoui, D. Hourlier

Organosilicon polymer-derived ceramic (PDC) materials have been extensively studied for their various properties such as mechanical, chemical and electrical properties. One of the least explored properties of PDC is their thermal properties, required for designing a heat energy converter. In this…
