Per-COVID-19: A Benchmark Dataset for COVID-19 Percentage Estimation from CT-Scans

Fares Bougourzi, Cosimo Distante, Abdelkrim Ouafi, Fadi Dornaika, Abdenour Hadid, Abdelmalik Taleb-Ahmed

COVID-19 infection recognition is a very important step in the fight against the COVID-19 pandemic. In fact, many methods have been used to recognize COVID-19 infection including Reverse Transcription Polymerase Chain Reaction (RT-PCR), X-ray scan, and Computed Tomography scan (CT- scan). In…

Three-dimensional trapping and dynamic axial manipulation with frequency-tuned spiraling acoustical tweezers: a theoretical study

Zhixiong Gong, Michael Baudoin

Holographic acoustical tweezers based on Archimedes-Fermat spiraling interdigitated transducers (SIDTs) are a versatile tool for the selective manipulation of microparticles [Baudoin et al., Sci. Adv. 5, eaav1967 (2019)] and cells [Baudoin et al., Nat. Commun., 11, 4244 (2020)] in a standard…

Event-Driven Continuous-Time Feature Extraction for Ultra Low-Power Audio Keyword Spotting

S. Mourrane, Benoit Larras, A. Cathelin, Antoine Frappé

In the context of autonomous keyword spotting and sound detection, this paper proposes a low power feature extraction unit generating spectrograms that represent a unique signature allowing the classification of audio signals. This system is composed of a continuous-Time digital signal processing…

Experimental and theoretical study of group delay times and density of states in one-dimensional photonic circuit

S. Khattou, M. Amrani, A. Mouadili, E.H. El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Bahram Djafari-Rouhani

We present a comparative study of density of states (DOS) and group delay times for a one-dimensional (1D) coaxial photonic crystal made of N cells attached horizontally along a waveguide. Using the interface response theory of continuous media, we derive exact analytical expressions relating the…

Experimental full wavefield reconstruction and band diagram analysis in a single-phase phononic plate with internal resonators

N. Kherraz, M. Radzieński, M. Mazzotti, P. Kudela, F. Bosia, A. S. Gliozzi, D. Misseroni, N. M. Pugno, W. Ostachowicz, M. Miniaci

Research on phononic crystal architectures has produced many interesting designs in the past years, with useful wave manipulation properties. However, not all of the proposed designs can lead to convenient realizations for practical applications, and only a limited number of them have actually been…

21 - Layered Photonic Crystals with Left-Handed Materials

Abdellatif Akjouj, El Houssaine El Boudouti, L. Dobrzynski, Bahram Djafari-Rouhani

We theoretically investigate the photonic band structure of layered photonic crystals composed of alternating layers of right- and left-handed materials (RHMs and LHMs). The dispersion curves are mainly studied by assuming that the dielectric permittivity and magnetic permeability are constant in…

Angular characteristics of multipath propagation in an indoor industrial environment

Aliou Bamba, Emmeric Tanghe, Aladji Kamagate, Pierre Laly, Frederic Challita, Adama Konate, Wout Joseph, M. Lienard, Davy Gaillot

The characteristics of multipath components (MPCs) are addressed in an industrial environment at 1.3 GHz by means of measurements with a multidimensional channel sounder. The maximum likelihood estimator, RiMAX, is used to determine the MPCs parameters and takes into account the diffuse scattering…

Non-Binary Parallel Turbo LDPC Codes Associated with High Order Constellation

Latifa Mostari, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Since the non-binary LDPC (Low-Density Parity-Check) codes offer better performance than binary LDPC codes for a system using high order constellations such as the QAM (Quadrature Amplitude Modulation), one proposes in this paper a high non-binary LDPC code, called a parallel nonbinary turbo LDPC…
