Competition of two Sulfurospirillum populations for tetrachloroethene

Tetrachloroethene (PCE) represents a major groundwater pollutant. Some bacteria are able to use PCE as electron acceptor in an anaerobic respiration process called organohalide respiration (OHR). An anaerobic enrichment culture (named SL2-PCEb) consisting ...

Amorphous silicon passivated contacts for diffused junction silicon solar cells

Aïcha Hessler-Wyser, Stefaan De Wolf, Bénédicte Demaurex

Carrier recombination at the metal contacts is a major obstacle in the development of high-performance crystalline silicon homojunction solar cells. To address this issue, we insert thin intrinsic hydrogenated amorphous silicon [a-Si: H(i)] passivating fil ...

Mixed Potentials for Planar Multilayered Structures Including Conductive Interfaces

Juan Ramon Mosig, Michael Mattes, Ioannis Koufogiannis

A complete and automatized strategy has been developed to derive the Vector and Scalar Potential Green’s Functions (GFs) of planar multilayered structures that include conductive sheets. The propagator matrix technique is enhanced to include conductive she ...

Architecture potentielle (Jonction, Genève)

Pauline Seigneur

“Fait frais ici non? Faut dire qu'on est presque à la campagne et puis y a l'eau… quand ils ouvrent les vannes en amont, ici t'as les pieds dans l'eau. J'venais souvent ici avant y avait moins de constructions, plus de terrains vagues…T'étais déjà venu? On ...

Charge collection in amorphous silicon solar cells: Cell analysis and simulation of high-efficiency pin devices

Christophe Ballif, Matthieu Despeisse, Michael Elias Stückelberger, Yannick Samuel Riesen, Brice Perruche

The drift length Ldrift=μτE within the i layer of a-Si:H solar cells is a crucial parameter for charge collection and efficiency. It is strongly reduced not only by light-induced reduction of μτ, but also by electric field deformation ΔE by charges near th ...

Phase extraction in speckle interferometry by a circle fitting procedure in the complex plane

Pierre Jacquot, Sébastien Equis

In speckle interferometry (SI), temporal signals are amplitude- and frequency-modulated signals and exhibit a fluctuating background. Prior to phase computation, this background intensity must be eliminated. Here our approach is to build a complex signal f ...

A NUMERICAL MANIFOLD METHOD FOR PLANE MICROPOLAR ELASTICITY

Hua Zhang, Jian Zhao, Gaofeng Zhao

A numerical manifold method (NMM) for plane micropolar elasticity is proposed in this paper to consider the microstructure influence of materials. First, the basic formulations of plane micropolar elasticity are briefly introduced. Then, the equations of s ...

Influence of bias voltage on the microstructure and physical properties of magnetron sputtered Zr–Si–N nanocomposite thin films

Rosendo Sanjines, Silviu Cosmin Sandu, David Oezer

e report an investigation concerning the influence of ion bombardment on the nanostructure and physical properties of Zr–Si–N nanocomposite thin films. The films were deposited by reactive magnetron sputtering from individual Zr and Si targets. The Si cont ...

On scalable source coding with decoder side informations

Suhas Diggavi

We consider the problem of scalable source coding with decoder side informations. Two special cases of this problem have been investigated in the literature, namely successive refinement Wyner-Ziv (SR-WZ) coding and side-information scalable (SI-Scalable) ...
