Dépôt par couche atomique spatiale (SALD)
Innovations technologiques, 2016L’ALD Spatial (SALD) est une variation de l’ALD ou les precurseurs sont injectes en des endroits differents, et separes par une region inerte. La croissance du film est realisee par exposition du substrat a des emplacements contenant des precurseurs ...

Spatial Variation in Abundance
Ecology, 1995To quantify the magnitude and pattern of spatial variation in local population density within a single species, we analyzed large numbers of samples, representing a large geographic area or a wide range of ecological conditions. Our analyses focused on, but were not limited to, censuses of birds recorded in the North American Breeding Bird Survey ...

SPATIAL VARIATION IN ABUNDANCE CREATED BY STOCHASTIC TEMPORAL VARIATION
Ecology, 1997A central question in ecology is explaining spatial variation in the abundance of species. Patterns of spatial variation in abundance can often be explained by spatial variation in the environment, including resource availability, climatic variables, and other factors that influence a species’ reproduction and survival. We show that spatial patterns in

Mimas’ far-UV albedo: Spatial variations
Icarus, 2012We present Cassini Ultraviolet Imaging Spectrograph (UVIS) observations of Mimas at far-ultraviolet wavelengths (170–190 nm) which show an interesting albedo gradient across the anti-saturnian hemisphere. We discuss the photometric behavior of Mimas in the far-UV and review the important exogenic processes and their expected effects, relevant over a ...

Hydroclimate spatial variations
2008Spatial scale Hydroclimate displays notable variations from place to place in response to multiple influences exerted by the Earth's climate system on the hydrologic cycle. These spatial variations exist on a continuum and produce an infinite number of hydroclimatic expressions.

Spatial variations in seismic motions
Canadian Journal of Civil Engineering, 1976A method for evaluating the spatial variations in strong seismic motions for a linear, homogeneous, and horizontally stratified soil layer system is presented. The procedure accounts for the focal depth and the epicentral distance, the corresponding angle of incidence, and the relative contributions of both shear and Rayleigh waves.

Spatial Variational Principles in Continuum Mechanics
Archive for Rational Mechanics and Analysis, 1984In this paper the author proposes a correction of the original variational principle of \textit{J. W. Herivel} [Proc. Camb. Philos. Soc. 51, 344-349 (1955; Zbl 0068.188)] taking into account the constraint expressing the conservation of the identity of the particle. The thermodynamic considerations are left out and only simplest boundary conditions are

Spatial and Temporal Indoor Radon Variations
Health Physics, 1992This paper examines the ability of standard radon measurement protocols to predict long-term radon concentrations in houses located in the upper Midwest. It was observed that: (1) significant radon variations can occur on a spatial scale as small as a single floor; (2) radon measurements that integrate for periods less than 3 mo are reliable only to ...
