MULTISCALE ANALYSIS OF ELECTRORHEOLOGICAL FLUIDS
International Journal of Modern Physics B, 2002We construct a microscale model for a rigid particle suspension in a viscous fluid that includes Maxwell electrostatic forces. Via homogenization techniques we characterize the properties the material exhibits at the macroscale. The change in the effective constitutive equations is due to the highly oscillating electrostatic forces.

Projective invariant multiscale analysis
Proceedings of 3rd IEEE International Conference on Image Processing, 2002Summary: By using the camera model for images acquisition, we present here a multiscale analysis \((T^P_t)\), \(t \in \mathbb{R}^+\), \(P \in \mathbf P\), which is invariant under the projective group. This analysis depends on two parameters. For every choice of the projective parameter \(P\), the restricted analysis \((T^P_t)\), \(t\in \mathbb{R ...

Homogenization and multiscale analysis
2019This chapter presents a survey of the homogenization and multiscale analysis of periodic, masonry walls subjected to in-plane loading conditions. The scale of the structure, macroscale, and that of the material, microscale, are introduced, invoking the assumption of the separation of the scales.

Multiscale Analysis and Wavelets
2009In this chapter we will introduce the wavelet transform with the purpose of obtaining better representation of images using atomic decompositions in the space-frequency domain.

Multivariate Multiscale Analysis
1990Abstract : The principal investigator produced five published papers during the period of support. The work centered on questions of Fourier/wavelet analysis. This is an area which promises to have a major impact on signal processing and numerical analysis and requires careful theoretical underpinning. Dr.

Multiscale analysis of failure
2008This chapter has dealt with the notion of loss of sustainability of an equilibrium state with constant control parameters. It was shown that an equilibrium state was non sustainable if and only if at least one incremental loading direction exists that leads to the vanishing of the macroscopic second-order work defined on the specimen scale.

Multiscale and multiresolution analysis
In this chapter, we describe the Gaussian scale-space in the spatial and intensity parameters, and we discuss the scale-selection algorithms for blob and edge detections. Image resolution is to some extent an artifact of the camera used, and with no prior knowledge, we seldomly can predict the size of objects in pixels in images.openaire +2 more sources
