Finite-element folds of similar geometry

Tectonophysics, 1976
Abstract Model folds of similar geometry have been produced by using the finite-element method and the constitutive relations of a layer of wet quartzite embedded in a marble matrix with an initially sinusoidal configuration and a 10° limb dip. The power law for steady-state flow of Yule Marble (Heard and Raleigh, 1972) is used for the matrix and our

Open-Circuit Fault Diagnosis Method for Grid-Connected Bidirectional T-Type Converter Based on Geometrical Similarity Measurement

IEEE transactions on power electronics, 2022
Grid-connected bidirectional T-type converter (GBTC) is widely used in power generation, vehicle-to-grid, and other applications because of its bidirectional energy flow and superior performance.

Geometry-Aware Graph Embedding Projection Metric Learning for Image Set Classification

IEEE Transactions on Cognitive and Developmental Systems, 2022
By describing image sets as linear subspaces on the Grassmann manifold, image set classification has received persistent attention. Despite the success made so far, the unhelpfully intraclass diversity and interclass similarity remain two key challenges ...

Network geometry

Nature Reviews Physics, 2020
Networks are finite metric spaces, with distances defined by the shortest paths between nodes. However, this is not the only form of network geometry: two others are the geometry of latent spaces underlying many networks and the effective geometry ...

Self-Similarity and Fractal Geometry

1995
If you cut a limb off a tree, the resulting object will resemble—in miniature—the tree itself. If you cut a branch off this limb, the shape of the resulting object will be similar to the limb and to the entire tree. If you cut a twig off this branch, it too will resemble the entire tree.

Harnessing the Universal Geometry of Embeddings

arXiv.org
We introduce the first method for translating text embeddings from one vector space to another without any paired data, encoders, or predefined sets of matches.

Geometry of Self-similar Sets

2014
Self-similar sets form a well-defined class of fractals which are relatively easy to study. This talk introduces their main features with a lot of examples. We explain the need of a separation condition for the tangential structure. Hausdorff measure is the natural concept of volume. Under certain conditions Hausdorff measures define also the “surface”

Generalizing Spatial Transformers to Projective Geometry with Applications to 2D/3D Registration

International Conference on Medical Image Computing and Computer-Assisted Intervention, 2020
Differentiable rendering is a technique to connect 3D scenes with corresponding 2D images. Since it is differentiable, processes during image formation can be learned. Previous approaches to differentiable rendering focus on mesh-based representations of

IGICP: Intensity and Geometry Enhanced LiDAR Odometry

IEEE Transactions on Intelligent Vehicles
Point matching and pose optimization are two important processes in LiDAR odometry. The former one is prone to noise and initial pose estimation, while the latter often falls into local minima due to improper matched points.

Geometry-based similarity retrieval of rotational parts

Proceedings. Second International Conference on Data and Knowledge Systems for Manufacturing and Engineering, 2003
In available retrieval and classification systems, parts are described using attributes comparable to those in traditional database systems. The authors suggest a system for retrieval of parts having geometric similarity which accesses a database system storing the geometric data provided by the CAD system.
