Dynamic textures: models and applications
"Temporal or dynamic textures are video sequences that are spatially repetitive and temporally stationary. Dynamic textures are temporal analogs of the more common spatial texture. They are a family of visual phenomena where the texture elements, or the spatially repeating elements, undergo …

Synthesis, Editing, and Rendering of Multiscale Textures
The study of textures---images with repeated visual content---has produced a number of useful tools and algorithms for analysis, synthesis, editing, rendering, and a variety of other applications. However, the recent rapid growth in data storage and computational abilities has expanded the notion …

Surface textures and other features of diamonds
… are reported. Forty-one pristine surface textures are distinguished, including twelve which are described for the first time. Only two surface textures are ascribed to crystal growth. The others are considered to result from crystal resorption and etching although internal features, such …

Textures and Entanglements of Contemporary Afrikaner Cinema
During the apartheid era, white Afrikaner cinema largely served the purpose of placating, soothing, and bolstering the white middle class. Today, more than twenty years after the end of this regime, scholars are intrigued by the large amount of escapist, paradoxical, and ineffectual works still …

Studying Electronic Textures with Coherent Lensless Imaging
X-ray microscopes have opened our collective eyes to the richness of nanoscale texture in systems such as correlated and quantum materials. These microscopes draw their power from the combination of short wavelengths, which provide high resolution, and interaction with atomic resonances, which …

An investigation of the deformation textures of titanium
… This study was undertaken (1) to determine the textures developed in titanium during cold rolling, (2) to determine why the observed textures of titanium differ from those of other hexagonal metals, and (3) to develop a satisfactory explanation of the deformation textures of …

Manipulation of spin textures by unconventional spin torques
… The manipulation of nonuniform magnetization textures such as domain walls and skyrmions provide both a means to control magnetism in devices, and to gain new fundamental insights into spin-charge and spin-orbital interactions in magnetic materials. In this thesis, we examine novel mechanisms …

Haptic simulation of naturally occuring textures and soil properties
Methods for developing realistic haptic (force feedback) simulations of soils and rocks are presented. Mathematical models of the dynamics of a virtual probe mechanically interacting with a virtual object are developed to provide the basis for analysis and simulation. The models then incorporate …

Evaluation of TIN extraction methods for various terrain textures
… 90th percentile errors for all types of terrain textures and Drop Heuristic was second best in most instances. The Hierarchy method was superior to VIP when less than 12% of the original DEM points were selected. When 12% of the original DEM points were selected, VIP outperformed the Hierarchy …

Using Metamorphic Textures to Infer Deformation and Thermodynamic Histories
Garnet porphyroblasts are commonly used to determine P-T conditions in metamorphic rock assemblages. However, the actual process of porphyroblast nucleation is still poorly understood and garnet growth may occur at different conditions than those predicted by equilibrium thermodynamics. It is …

Aqueous & Non-Aqueous Phase Tracer Migration Through Differing Soil Textures
The National Grid Transco Company sponsored this project in order to promote the understanding of NAPL migration through b-horizon soils and retarding effects upon non aqueous species migration. Soil structure and texture was also studied using conservative (Bromide) and non-conservative …
