A symmetry analysis and a semi analytical exact model are proposed to describe the mechanical, piezoelectric and electronic properties of strained wurtzite quantum nanostructures (QNs) with axial symmetry. An expression of the piezoelectric polarization is given as a function of inhomogeneous strains. The 3D 8x8 strained k.p Hamiltonian is reduced to 2D using the total angular momentum represen...

Classes of‎ ‎Abaffy-Broyden-Spedicato (ABS) methods have been introduced for‎ ‎solving linear systems of equations‎. ‎The algorithms are powerful methods for developing matrix‎ ‎factorizations and many fundamental numerical linear algebra processes‎. ‎Here‎, ‎we show how to apply the ABS algorithms to devise algorithms to compute the WZ and ZW‎ ‎factorizations of a nonsingular matrix as well as...

Distributed video coding (DVC) is a new video coding paradigm based on two key Information Theory results: the Slepian-Wolf and Wyner-Ziv theorems. Recently, promising results were shown in Wyner-Ziv (WZ) video coding, a particular case of DVC. In the literature, many practical WZ coding approaches model the correlation noise between the original frame and the so-called side information by a gi...

Combining density functional theory and the nonequilibrium Green's function method, we investigate the thermoelectric properties of thin GaAs nanowires (NWs). After identifying the most stable structures for GaAs NWs, either in wurtzite (wz) or zinc blende (zb) stacking, we present a systematic analysis on the thermoelectric properties of these NWs and their dependence on stacking type (wz or z...

Wyner–Ziv (WZ) to scalable video coding (SVC) transcoding can offer a suitable framework to support scalable video communications between low-cost devices. In addition, the video delivery provided by SVC covers the needs of a wide range of homogeneous networks and different devices. Despite the advantages of the video transcoding framework, the transcoder accumulates high complexity and it must...

One or more heavy spin-1 fields may replace the Higgs boson in keeping perturbative unitarity up to a few TeV while at the same time account for the electroweak precision tests. We study the Drell-Yan production of heavy vector and axial-vector states in generic Higgsless models at hadron colliders. We analyse in particular the l+l−, WZ, and three SM gauge boson final states. In the l+l− case w...

In this paper the authors have carried out simulation experiment to study the opto-electric properties of p+-p-n-n+ structured WurtziteGaN (Wz-GaN) Reach-Through Avalanche Photodiodes (RAPDs). The photo responsivity and optical gain of the device are obtained within the wavelength range of 300 to 450 nm using a novel modeling and simulation technique developed by the authors. Two optical illumi...
