Medical video coding based on 2nd-generation wavelets: performance evaluation

Merzak Ferroukhi, Abdeldjalil Ouahabi, Mokhtar Attari, Yassine Habchi, Abdelmalik Taleb-Ahmed

The operations of digitization, transmission and storage of medical data, particularly images, require increasingly effective encoding methods not only in terms of compression ratio and flow of information but also in terms of visual quality. At first, there was DCT (discrete cosine transform) then…

Thermal Stability of Oleate‐Stabilized Gd2O2S Nanoplates in Inert and Oxidizing Atmospheres

Clément Larquet, D. Hourlier, Anh-Minh Nguyen, Almudena Torres-Pardo, Andrea Gauzzi, Clément Sanchez, Sophie Carenco

Capping ligands play an important role in the chemistry of nanoparticles synthesized with organic surfactants. This is relevant to a number of device applications where heating may cause major modifications of crystalline nanoparticles including amorphization, surface rearrangements or sintering.…

Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals

Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present the realization of the topological valley-protected zero-order antisymmetric (A 0) or symmetric (S 0) and zero-order shear-horizontal (SH 0) Lamb waves at different domain walls based on topologically distinct asymmetric double-sided pillared phononic crystals. The elastic periodic…

Chapter 6 - One-dimensional magnonic crystals

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents examples of bulk and surface magnons of one-dimensional magnonic crystals, called also superlattices. The such man-made crystals considered here are grown out of semiinfinite stacks of two and also three different ferromagnetic slabs. Each slab is modeled by a simple cubic…

The Influence of Microstructure on the Passive Layer Chemistry and Corrosion Resistance for Some Titanium-Based Alloys

Nader El-Bagoury, Sameh Ahmed, Ola Ahmed Abu Ali, Shimaa El-Hadad, Ahmed Fallatah, G. Mersal, Mohamed Ibrahim, Joanna Wysocka, Jacek Ryl, Rabah Boukherroub, Mohammed A. Amin

The effect of microstructure and chemistry on the kinetics of passive layer growth and passivity breakdown of some Ti-based alloys, namely Ti-6Al-4V, Ti-6Al-7Nb and TC21 alloys, was studied. The rate of pitting corrosion was evaluated using cyclic polarization measurements. Chronoamperometry was…

Buffer breakdown in GaN-on-Si HEMTs: A comprehensive study based on a sequential growth experiment

Matteo Borga, Matteo Meneghini, Davide Benazzi, Eleonora Canato, Roland Püsche, Joff Derluyn, Idriss Abid, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to investigate the breakdown mechanisms of the layers constituting the vertical buffer of GaN-on-Si HEMTs; in addition, for the first time we demonstrate that the breakdown field of the AlN nucleation layer grown on a silicon substrate is equal to 3.2 MV/cm and evaluate its…

Chapter 3 - Magnon mono-mode circuits: serial loop structures

Housni Al-Wahsh, Abdellatif Akjouj, L. Dobrzynski, Bahram Djafari-Rouhani

In this chapter and in the frame of long-wavelength Heisenberg model, simple magnonic mono-mode circuits are designed to obtain transmission stop (pass) bands where the propagation of spin waves is forbidden (allowed). These simple devices are composed of infinite one-dimensional mono-mode…

Chapter 5 - Surface, interface, and confined slab magnons

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents simple examples of surface, interface, and confined slab magnons. It addresses also magnetic surface reconstructions due to soft surface magnons. The influence of surface-pinning fields on the spin contribution to the thermodynamic properties of a ferromagnet is also presented…
