Local impact of dust storms around a suburban building in arid and semi-arid regions: numerical simulation examples from Dubai and Riyadh, Arabian Peninsula

D. Doronzo, E. Khalaf, P. Dellino, D. de Tullio, F. Dioguardi, Lucia Gurioli, D. Mele, G. Pascazio, R. Sulpizio

Dust storms are common in arid and semi-arid regions, e.g., the Arabian Peninsula, where undisturbed wind can either weather the rocks and transport the grains for kilometers over the landscape or even overseas, or form dunes and ripples. We used a multiphase Eulerian–Lagrangian computational fluid...

AlGaN/GaN HEMT's photoresponse to high intensity THz radiation

Nina Diakonova, Dmytro But, Dominique Coquillat, Wojciech Knap, C. Drexler, P. Olbrich, J. Karch, M. Schafberger, S. D. Ganichev, Guillaume Ducournau, Christophe Gaquière, M. -A. Poisson, S. Delage, G. Cywinski, C. Skierbiszewski

We report on the photoresponse dependence on the terahertz radiation intensity in ALGaN/GaN HEMTs. We show that the ALGaN/GaN HEMT can be used as a THz detector in CW and in pulsed regime up to radiation intensity of several kW/cm2. The dynamic range in the pulsed regime of detection can be more...

Theoretical investigation of single dopant in core/shell nanocrystal in magnetic field

Abdelkrim Talbi, E. Feddi, A. Oukerroum, E. Assaid, F. Dujardin, M. Addou

The control of single dopant or ``solitary dopant'' in semiconductors constitute a challenge to achieve new range of tunable optoelectronic devices. Knowing that the properties of doped monocrystals are very sensitive to different external perturbations, the aim of this study is to...

Sub-10 nm-scale capacitors and tunnel junctions measurements by SMM coupled to RF interferometry

F. Wang, Thomas Dargent, D. Ducatteau, Gilles Dambrine, Kamel Haddadi, N. Clement, Didier Theron, Bernard Legrand

We have developed an adjustable Interferometer combined to a Scanning Microwave Microscopy (ISMM) to characterize the impedance of thousands of nanocapacitors. The adjustable interferometer allows the choice of the interference frequency within ± 50 MHz as well as the choice of the impedance range...

Energy Consumption of Networked Embedded Systems

Nadir Cherifi, Gilles Grimaud, Thomas Vantroys, Alexandre Boé

The Web of Things (WoT) defines the idea of addressing and requesting any surrounding connected device through web applications. These devices are for a large part, tiny, wireless and mostly battery-powered. Therefore, energy represents a critical limiting resource for their large scale deployment...

Experimental Analysis and Modelling of Coaxial Transmission Lines with Soft Shield Defects

Hossein Manesh, Abelin Kameni, Florent Loete, Jérôme Genoulaz, Lionel Pichon, Odile Picon

Significant research has focused on the diagnosis of “hard” faults (open and short circuits) in transmission lines, but there has been much less work on “soft” faults resulting from a very small change in line impedance. This research is based on one type of soft fault problems in electrical fault...
