Textural singularities in superfluid3He-B
Journal of Low Temperature Physics, 1977The absorption signal occasionally found missing in the middle of resonance absorption lines in NMR is explained on the basis of a textural singularity of the anisotropy axis in the B phase of3He. The singularity combines with the field gradient present to give rise to an asymmetric hole in the signal with a singularity on the high-frequency side.

Physica B: Condensed Matter, 1992
Abstract By separation of the soft degrees of freedom in the Leggett equations of spin dynamics, the equations of motion for textures in 3He-B are derived. These equations are applied to the analysis of motions of spatially uniform textures in magnetic field in a bulk liquid and in a slab geometry.

Texture Analysis of Ultrasound B-Mode Images by Segmentation
Ultrasonic Imaging, 1984B-mode texture characterization by supervised methods of pattern recognition is subject to the following drawbacks: precise localization of the lesion to characterize is often difficult and, even when the lesion is well isolated, its texture can be corrupted by the presence of tumor non specific structures.

Collective-mode spectroscopy of textures in superfluid3He-B
Journal of Low Temperature Physics, 1989A phenomenological theory for the propagation of the real squashing modes in superfluid3He-B is presented. This allows one to calculate the splitting of the real squashing (rsq) mode spectrum caused by the combined effects of magnetic field, dispersion, and texture in the experimentally important range of magnetic fields from 0 to 103 Gauss.

Synthesis of fine details in B picture for dynamic textures
2017 IEEE International Conference on Image Processing (ICIP), 2017Dynamic textures are characterized with irregular motions that are often challenging for motion compensation as applied in the state of the art video codecs. Due to rapid and randomly evolving nature of such a signal, it is accompanied with very high energy in the residual.

NMR measurement on textures in rotating superfluid 3He-B
AIP Conference Proceedings, 1983Results from cw NMR measurements on superfluid 3He‐B in rotation are discussed. The measurements have been performed with the magnetic field oriented at different angles with respect to the rotation axis. The results illustrate the effect of rotation on different order parameter textures in a cylindrical container.

Texture Development in Dual Phase a/B-Brass - Part II: Recrystallization Textures
International Journal of Materials Research, 1995The development of the crystallographic texture in two phase α/β-brass Cu-40 % Zn containing 20 vol.% β phase was investigated separately for both phases by means of 3-dimensional orientation distribution functions (ODFs). The results were compared to those of the single phase alloy Cu-37% Zn and to literature data of Cu-30% Zn. Whereas the development

Textures and spin waves in rotating superfluid3H3-B
Journal of Low Temperature Physics, 1983The spin wave modes in rotating superfluid3He-B have been calculated for a texture of cylindrical symmetry. The textural configuration is determined by minimizing the appropriate free energy and solving the resulting Euler-Lagrange equations for then vector. The texture determines the effective potential entering the spin wave equation.

Rolling texture in the intermetallic compound Ni76Al24(B)
Materials Science and Engineering: A, 1998The development of cold rolling texture in the intermetallic compound Ni3Al(B) has been investigated as a function of rolling reduction, using the conventional pole figure as well as the orientation distribution functions (ODF) method. The textures at low degrees of deformation have been found to be similar to the rolling texture of pure Ni cold rolled
