Magnetic Target Linear Location Method Using Two-Point Gradient Full Tensor

IEEE Transactions on Instrumentation and Measurement, 2021
Presently used magnetic target location methods are greatly affected by geomagnetism and involve complex solution processes. To address these problems, herein, a linear location method based on the two-point magnetic gradient full tensor is proposed ...

Shape from focus based on 3D structure tensor using optical microscopy

Microscopy research and technique (Print), 2020
Shape from focus (SFF) is a widely used passive optical method for 3D shape reconstruction. In SFF, a focus measure, which is used to estimate the relative focus level, plays a critical role in depth estimation.

ExTensor: An Accelerator for Sparse Tensor Algebra

Micro, 2019
Generalized tensor algebra is a prime candidate for acceleration via customized ASICs. Modern tensors feature a wide range of data sparsity, with the density of non-zero elements ranging from 10-6% to 50%.

The Amygdala in Schizophrenia and Bipolar Disorder: A Synthesis of Structural MRI, Diffusion Tensor Imaging, and Resting-State Functional Connectivity Findings

Harvard Review of Psychiatry, 2019
Frequently implicated in psychotic spectrum disorders, the amygdala serves as an important hub for elucidating the convergent and divergent neural substrates in schizophrenia and bipolar disorder, the two most studied groups of psychotic spectrum ...

Tensors in special relativity

2009
Abstract Tensors in a general coordinate system are introduced. When a tensor is expanded in terms of a set of basis (or inverse basis) vectors, the coefficients of expansion are its contravariant (or covariant) components with respect to this basis.

An Effective Tensor Completion Method Based on Multi-linear Tensor Ring Decomposition

Asia-Pacific Signal and Information Processing Association Annual Summit and Conference, 2018
By considering the balance unfolding scheme does help to catch the global information for tensor completion and the recently proposed tensor ring decomposition, in this paper a weighted multilinear tensor ring decomposition model is proposed for tensor ...

Tensors in general relativity

2009
Abstract Differentiation of tensor components in a curved space must be handled with extra care. By adding another term (related to Christoffel symbols) to the ordinary derivative operator, we can form a “covariant derivative”; such a differentiation operation does not spoil the tensor property.

Relativity, Tensors, and Curvature

2011
Heuristics of Einstein's Theory What does g00 have to do with gravitation? The Metric Potentials Einstein's general theory of relativity is primarily a replacement for Newtonian gravitation and a generalization of special relativity. It cannot be “derived”; we can only speculate, with Einstein, by heuristic reasoning, how such a generalization ...
