Face Sketch Synthesis using Generative Adversarial Networks

Mahfoud Sami, Daamouche Abdelhamid, Bengherabi Messaoud, Boutellaa Elhocine, Abdenour Hadid

Face Sketch Synthesis is crucial for a wide range of practical applications, including digital entertainment and law enforcement. Recent approaches based on Generative Adversarial Networks (GANs) have shown compelling results in image-to-image translation as well as face photo-sketch synthesis....

Spectrum Sensing Using Software Defined Radio for Cognitive Radio Networks: A Survey

Julio Manco-Vasquez, Iyad Dayoub, Amor Nafkha, Mohammad Alibakhshikenari, Hayfa Ben Thameur

Cognitive radio (CR) network has emerged as a potential solution to the under-utilization problem of the allocated radio spectrum, where spectrum sensing (SS) plays a key role to enable the coexistence between primary and secondary users. It has attracted research interests, and several works have...

Frequency response optimization of P-I-N photodiode based on InGaAsN lattice matched to GaAs for High-Speed photodetection applications

R. Amraoui, Abdelkader Aissat, Jean-Pierre Vilcot, Didier Decoster

This paper reports on pin photodiode frequency response optimization based on InxGa1-xAs1-yNy quaternary lattice matched to GaAs. Two transparent layers are placed on p-side and n-side in order to manage the photodiode frequency response limitations. The lattice matching condition is calculated in...

Catch and release strategy of matrix metalloprotease aptamers via thiol–disulfide exchange reaction on a graphene based electrochemical sensor

Vladyslav Mishyn, Merve Aslan, Adrien Hugo, Teresa Rodrigues, Henri Happy, Rana Sanyal, Wolfgang Knoll, Florence Baudoux, Vincent Bouchiat, Rostyslav Bilyy, Rabah Boukherroub, Amitav Sanyal, Sabine Szunerits

Matrix metalloproteases (MMP) are a large family of proteases, which synergistically degrade abundant extracellular matrix and play an essential role in tissue degradation and remodelling. Sensing of MMP levels, notably the pro- and activated matrix metalloproteinases (MMP-2 and MMP-9), would...

Elaboration and characterization of porous ultrathin gold films grown by ion beam assisted deposition

Abdelhanin Aassime, Marc Duquennoy, Frédéric Hamouda, Tahar Kadi, Frédéric Mahut, Mohammadi Ouaftouh

The growth of ultrathin gold layers on a silicon substrate is performed with an unconventional ion beam assisted deposition. In this setup, evaporated gold flow and ion beam flux are perpendicular. 5 and 10 nm thick gold were deposited on tilted samples with the assistance of an argon ion beam at...

Electrochemical H2 Production using Polypyrazole based Zinc(II) Complex in Alkaline Medium

Mohamed Ibrahim, Gaber A.M. Mersal, Ahmed Fallatah, Rabah Boukherroub, Safaa Abdou, Mohammed Amin

A zinc(II) complex of polypyazole containing ligand namely, [Tp*ZnCl] (Zn1) {Tp* = tris(3,5-dimethylpyrazolyl)borate}, along with its zinc(II) bound hydroxo complex [Tp*Zn–OH] (Zn2) were synthesized and characterized by FT-IR, Raman, 1H NMR techniques and elemental analysis. In alkaline solution (0...

A comparison of pad metallization in miniaturized microfabricated silicon microcantilever-based wafer probes for low contact force low skate on-wafer measurements

Khadim Daffe, Jaouad Marzouk, Christophe Boyaval, Gilles Dambrine, Kamel Haddadi, S. Arscott

Miniaturized, microfabricated microelectromechanical systems (MEMS)-based wafer probes are used here to evaluate different contact pad metallization at low tip forces (<mN) and low skate on the on-wafer pads. The target application is low force RF probes for on-wafer measurements which cause...

Nanostructures wetting evaluation using ultra high frequency ultrasound

Abbas Salhab, Julien Carlier, Malika Toubal, Pierre Campistron, Marc Neyens, Bertrand Nongaillard, V. Thomy

Ultrasounds are a great tool for defects detection particularly for optically non-transparent materials. Hence, working at very high frequency (#GHz) allows the detection of nanoscale contact defects at the interface between two materials and especially in the presence of air, which has negligible...

Can classical surface plasmon resonance advance via the coupling to other analytical approaches?

David Geilfuss, Rabah Boukherroub, Jakub Dostalek, Wolfgang Knoll, Jean-Francois Masson, Antje Baeumner, Sabine Szunerits

For nearly 40 years, surface plasmon resonance (SPR) analysis has been used to better understand the binding interaction strength between surface immobilized bioreceptors and the analytes of interest. The advantage of surface plasmon resonance, over other affinity sensing approaches such as Western...

Wafer-level vapor cells filled with laser-actuated hermetic seals for integrated atomic devices

Vincent Maurice, Clément Carlé, Shervin Keshavarzi, Ravinder Kumar Chutani, Samuel Queste, Ludovic Gauthier-Manuel, Jean-Marc Cote, Rémy Vicarini, Moustafa Abdel Hafiz, Rodolphe Boudot, Nicolas Passilly

Atomic devices such as atomic clocks and optically-pumped magnetometers rely on the interrogation of atoms contained in a cell whose inner content has to meet high standards of purity and accuracy. Glass-blowing techniques and craftsmanship have evolved over many decades to achieve such standards...
