In this paper, we present a simple but effective color space conversion method for converting high precision YUV signals to 24-bit RGB signals. Compared to conventional color conversion method, our proposed method preserves more precisely the luminance information of the original YUV signal, while the chrominance difference is kept within a tolerable range. This method results in a smoother perception...
Overcomplete independent component analysis (ICA) is a challenge of ICA to estimate more sources from less mixtures. The statistical properties of the sources such as sparsity are often assumed to solve the problem. Other available information about the sources such as waveform, however, is scarcely used. Motivated by the fact that semi-blind ICA in complete case can improve the potential of ICA by...
We apply a new bootstrap statistical technique to distinguish between dasiaskillpsila and dasialuckpsila for individual funds. This methodology allows for non-normality in the idiosyncratic risk of the funds-a major issue when considering those funds which appear to be either very good or very bad performers, since these are the funds which investors are primarily interested in identifying. Our bootstrap...
PZT fibers have many important using in sensors, actuators and transducers. PZT fibers have been successfully fabricated by much technology, such as Sol-Gel method, extrusion method and so on, but for the micro-reactor method very little study work has been done. Porous, structurally-ordered active carbon was used in this work. Due to a high rate of pore with microns diameter, millimeters length,...
(Na0.5Bi0.5)0.94Ba0.06TiO3 (NBBT) powders are prepared by hydrothermal synthesis process. The effects of process conditions on the structure of NBBT are studied. In addition, effect of surface performance of NBBT powders is discussed with the amount of coupling agent increasing. The structure and property of the resulted powders were characterized by X-Ray diffraction (XRD). The granularity distribution...
