Quartiers résidentiels périurbains en transition : Comparaison multicritère de scénarios prospectifs à l'horizon 2050
Since the Industrial Revolution, urban spaces have undergone a profound reorganisation in parallel with a transformation of society and lifestyles. Urban sprawl has become widespread in Switzerland, as in countless countries, due to continuous innovations ...
EPFL2019Growth kinetics and morphological analysis of homoepitaxial GaAs fins by theory and experiment
Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Martin George Friedl, Lea Ghisalberti
Nanoscale membranes have emerged as a new class of vertical nanostructures that enable the integration of horizontal networks of III-V nanowires on a chip. To generalize this method to the whole family of III-Vs, progress in the understanding of the membra ...
AMER PHYSICAL SOC2018Sample and population exponents of generalized Taylor's law
Andrea Rinaldo, Andrea Giometto, Amos Maritan
Taylor's law (TL) states that the variance V of a nonnegative random variable is a power function of its mean M; i.e., V = aM(b). TL has been verified extensively in ecology, where it applies to population abundance, physics, and other natural sciences. It ...
Natl Acad Sciences2015An experimental comparison of silica gel and quartz sand grains as sediment media for growing vegetation at the laboratory scale
Paolo Perona, Peter Molnar, Zhe Jiang
In this technical note we compare silica gel grains and quartz sand as sediment media for vegetation root growth in laboratory experiments for ecohydrology and ecohydraulics. Silica gel grains become quite transparent when saturated with water. This would ...
Springer Verlag2009Site-Controlled InGaAs Quantum Dots with Tunable Emission Energy
Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Marco Felici, Arun Mohan
Semiconductor quantum-dot (QD) systems offering perfect site control and tunable emission energy are essential for numerous nanophotonic device applications involving spatial and spectral matching of dots with optical cavities. Herein, the properties of or ...
2009Growth parameters and shape specific synthesis of silicon nanowires by the VLS method
In this paper the effect of varying temperature, pressure and chemical precursors on the vapour-liquid-solid (VLS) growth of silicon nanowires (Si NWs) have been investigated. Some aspects of nucleation and growth mechanisms are discussed. Control on Si NW ...
2008Colloidal strategies for preparing oxide-based hybrid nanocrystals
A review. Recent progress of colloidal chem. in the prepn. of multimaterial nanostructures incorporating transition-metal oxides is reviewed. Attention is focused on the emerging class of hybrid nanocrystals (HNCs), in which domains of different materials ...
2008Dynamic feature selection for hardware prediction
Most hardware predictors are table based (e.g. two-level branch predictors) and have exponential size growth in the number of input bits or features (e.g. previous branch outcomes). This growth severely limits the amount of predictive information that such ...
2006Study of symbiotic, serological and antibiotic resistance characteristics of different Rhizobium cicerii strains
The symbiotic performance of 24 isolates of Rhizobium Cicerii, collected from different Tunisien soils, were studied in a growth room and compared to the performance of two international strains (Som and 43). The antibiotic and serologic tests showed a lar ...
1996Mechanism of the Transition from Fractal to Dendritic Growth of Surface Aggregates
THE similarity of many patterns formed in non-equilibrium growth processes in physics, chemistry and biology is conspicuous, and many attempts have been made to discover common mechanisms underlying their formation(1). A central question is what causes som ...
