Isotopic compositions of U and Pb were determined for relict zircon inclusions recovered from Muong Nong-type tektites from the Australasian and North American strewn fields. These inclusions are generally opaque white with granular textures, probably representing mechanical disaggregation and/or local melting and recrystallization. All zircons have strongly discordant U–Pb isotopic ratios and ...

BACKGROUND Early discrimination between transient and persistent par-solid ground-glass nodules (PSNs) at CT is essential for patient management. The objective of our study was to retrospectively investigate the value of texture analysis in differentiating pulmonary transient and persistent PSNs in addition to clinical and CT features. METHODS This retrospective study was performed with IRB a...

The purpose of this study was to find the effect purple sweet potato flour (Ipomoea batatas L.) and wheat ratio produce cilok with best characteristics. This used a Completely Randomized Design 5 levels ratio, namely 0%:100%, 10%:90%, 20%:80%, 30%:70%, 40%:60%. treatment repeated 3 times obtain 15 experimental units. Parameters observed were water content, ash protein fat carbohydrate crude fib...

The purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof Nodushan, Yazd. The plant species cover and the environmental variables were measured at 9 sites. Soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. Vegetation was classified using twowayindicator species analysis (TWINSPAN). Data was analyzed u...

Research on the comparative morphology of pollen grains depends crucially on the application of appropriate microscopy techniques. Information on the performance of microscopy techniques can be used to inform that choice. We compared the ability of several microscopy techniques to provide information on the shape and surface texture of three pollen types with differing morphologies. These techn...

Multi−View display technology allows the presentation of a 3D video by showing simultaneously several views of the same scene. One approach to render these multiple views is to synthesize novel views using a Depth Image Based Rendering (DIBR) algorithm. Consequently, for the efficient transmission of 3D video signals, the compression of texture and also the depth images is required. Since the r...

COMPLEX DIRECTIONAL WAVELET TRANSFORMS: REPRESENTATION, STATISTICAL MODELING AND APPLICATIONS AN PHUOC NHU VO, Ph.D. The University of Texas at Arlington, 2008 Supervising Professor: Soontorn Oraintara The thesis presents an new image decomposition for feature extraction, which is called the pyramidal dual-tree directional filter bank (PDTDFB). The image representation has an overcomplete ratio...

This paper proposes a novel 9/7 wavelet filter bank for texture image coding applications based on lifting a 5/3 filter to a 7/5 filter, and then to a 9/7 filter. Moreover, a one-dimensional optimization problem for the above 9/7 filter family is carried out according to the perfect reconstruction (PR) condition of wavelet transforms and wavelet properties. Finally, the optimal control paramete...
