Light Field Tensor Recovery
Pierre Vandergheynst, Mahdad Hosseini Kamal
This paper presents a novel approach to capture light field in camera arrays based on the tensor recovery framework. Light fields are acquired by a linear array of cameras with overlapping field of view. We represent the light fields in shape of a tensor t ...
2012Low-rank tensor Krylov subspace methods for parametrized linear systems
Daniel Kressner, Christine Tobler
We consider linear systems A(alpha)x(alpha) - b(alpha) depending on possibly many parameters alpha = (alpha(1), ... , alpha(p)). Solving these systems simultaneously for a standard discretization of the parameter range would require a computational effort ...
Society for Industrial and Applied Mathematics2011Spinning conformal correlators
We develop the embedding formalism for conformal field theories, aimed at doing computations with symmetric traceless operators of arbitrary spin. We use an index-free notation where tensors are encoded by polynomials in auxiliary polarization vectors. The ...
Springer2011Differential geometry applied to crystallography
The mathematical facet of modern crystallography is essentially based on analytical geometry, linear algebra as well as group theory. This study endeavours to approach the geometry and symmetry of crystals using the tools furnished by differential geometry ...
EPFL2009Determination of chemical shift anisotropy tensors of carbonyl nuclei in proteins through cross-correlated relaxation in NMR
The principal components and orientations of the chem. shift anisotropy (CSA) tensors of nearly all 13C carbonyl nuclei in a small protein have been detd. in isotropic soln. by a combination of three complementary cross-correlation measurements. [on SciFin ...
2004Efficient scattering calculations in complex backgrounds
The utilization of the Green's tensor associated with a complex optical background (surface, cavity or stratified medium) leads to a dramatic reduction of the computation effort associated with scattering calculations in that background. This approach is i ...
2004Induced magnetic fields in aromatic [n]-annulenes-interpretation of NICS tensor components
The components of nucleus-independent chem. shift (NICS) tensors for Dnh n-annulenes are discussed as indexes of the arom. character of electronic pi systems. The component corresponding to the principal axis perpendicular to the ring plane, NICSzz, is fou ...
2004Green's tensor technique for scattering in two-dimensional stratified media
We present an accurate and self-consistent technique for computing the electromagnetic held in scattering structures formed by bodies embedded in a stratified background and extending infinitely in one direction (two-dimensional geometry), With this fully ...
2001Accurate solution of the volume integral equation for high-permittivity scatterers
We present a formalism based on the method of moment to solve the volume integral equation using tetrahedral (3-D) and triangular (2-D) elements. We introduce a regularization scheme to handle the strong singularity of the Green's tensor. This regularizati ...
Institute of Electrical and Electronics Engineers2000Gauge freedom for gravitational wave problems in tensor-scalar theories of gravity
A specific choice of gauge is shown to imply a decoupling between the tensor and scalar components of gravitational radiation in the context of Brans–Dicke-type theories of gravitation. The comparison of the predictions of these theories with those of gene ...
