STORING AND QUERYING SPATIALLY VARYING DATA QUALITY INFORMATION USING AN INTEGRATED SPATIAL RDBMS
quality spatial variation metadata sub-feature variation spatial database

2015/9/28
Current representations of spatial data quality (SDQ) do not adequately represent the spatial variation of SDQ. For example, a user who wants to know the positional accuracy of a feature usually has t...
Shear band in sand with spatially varying density
Bifurcation Digital Image Correlation Heterogeneous sand Shear band Strain localization

2015/7/1
Bifurcation theory is often used to investigate the inception of a shear band in a homogeneously deforming body. The theory predicts conjugate shear bands that have the same likelihood of triggering. ...

This paper considers control design for distributed systems, where the controller is to adopt and preserve the spatial structure of the system. Specifically systems that vary spatially are considered;...
Spatially varying predictors of teenage birth rates among counties in the United States

Background: Limited information is available about teenage pregnancy and childbearing in rural areas, even though approximately 20 percent of the nation’s youth live in rural areas. Identifying whethe...

Wind direction plays an important role in the spread of pollutant levels over a geographical region. We discuss how to include wind directional information in the covariance function of spatial models...

We discuss a class of lasing modes created by a spatially inhomogeneous gain pro le. These lasing modes are \extra modes", in addition to, and very di erent from, conventional lasing modes,which arise...
Fluid-induced pattern-formation in 3D photonic crystals with spatially varying surface functionalization
3D photonic spatially varying surface functionalization
font style='font-size:12px;'>
2010/12/28
We introduce a 3D porous photonic crystal whose inner surfaces are chemically functionalized in arbitrary spatial patterns with micro-scale resolution. We use this platform to demonstrate pattern-form...
Variational Denoising of Partly Textured Images by Spatially Varying Constraints
image denoising texture processing spatially varying fidelity term nonlinear diffusion variational image processing
font style='font-size:12px;'>
2010/1/7
Denoising algorithms based on gradient dependent regularizers, such as nonlinear-diffusion processes and total variation denoising, modify images towards piecewise constant functions.
Although edge s...
Graphically dependent and spatially varying Dirichlet process mixtures
local clustering global clustering mixture models nonparametric Bayes Dirichletprocess Gaussian process graphical model spatial dependence
font style='font-size:12px;'>
2010/3/9
We consider the problem of clustering grouped and functional data, which are indexed by
a covariate, and assessing the dependency of the clustered groups on the covariate. We assume
that each observ...
