DEFECT LINES, DUALITIES AND GENERALISED ORBIFOLDS [PDF]
XVIth International Congress on Mathematical Physics, 2010 Defects are a useful tool in the study of quantum field theories. This is illustrated in the example of two-dimensional conformal field theories. We describe how defect lines and their junction points appear in the description of symmetries and order-disorder dualities, as well as in the orbifold construction and a generalisation thereof that covers ...

Potts Models with a Defect Line [PDF]
Communications in Mathematical Physics, 2018 We provide a detailed analysis of the correlation length in the direction parallel to a line of modified coupling constants in the ferromagnetic Potts model on $\mathbb{Z}^d$ at temperatures $T>T_c$. We also describe how a line of weakened bonds pins the interface of the Potts model on $\mathbb{Z}^2$ below its critical temperature. These results are

A scaling limit for line and surface defects
Journal of High Energy Physics, 2022 We study symmetry-breaking line defects in the Wilson-Fisher theory with O(2N + 1) global symmetry near four dimensions and symmetry-preserving surface defects in a cubic model with O(2N) global symmetry near six dimensions.

Development status and improvement strategy of in-line inspection technology and management
You-qi chuyun, 2020 Pipeline defects have always been the dominant factor leading to pipeline failure. Using in-line inspectiontechnology to inspect and identify various pipeline defects has become a widely acknowledged practice in Chinaand abroad.

Characterization of defect structures in nanocrystalline materials by X-ray line profile analysis [PDF]
, 2007 X-ray line profile analysis is a powerful alternative tool for determining dislocation densities, dislocation type, crystallite and subgrain size and size-distributions, and planar defects, especially the frequency of twin boundaries and stacking faults.

On-linesurface defect detection for steel rails based on multi-line lasers
工程科学学报, 2021 Multi-line lasers were applied to the on-line defect detection for steel rails instead of single-line laser,which solved the problem of "pseudo defects" due to the vibration of rails under the mode of single-line laser.

Detection and Evaluation Method of Transmission Line Defects Based on Deep Learning
IEEE Access, 2020 The issues of existing research on transmission line detection include the following three: only detects a few categories, no open transmission line component dataset, and no unified, comprehensive evaluation index.

Line-defect calibration for line-scanning projection display
Optics Express, 2009 A method of line-defect calibration for line-scanning projection display is developed to accomplish acceptable display uniformity. The line scanning display uses a line modulating imaging and scanning device to construct a two-dimensional image. The inherent line-defects in an imaging device and optical lenses are the most fatal performance-degrading ...

Pseudospin-Polarized Topological Line Defects in Dielectric Photonic Crystals [PDF]
IEEE Transactions on Antennas and Propagation, 2019 Electromagnetic (EM) topological insulators have been extensively explored due to the robust edge states they support. In this work, we propose a topological EM system based on a line defect in topologically nontrivial photonic crystals (PCs).
