At low bit-rates, the conventional image coding standards, e.g., JPEG and JPEG 2000, do not have good compression performance due to the insufficiency of coding bits. A common solution to this problem is downsampling before encoding and reconstruction after decoding. Inspired by the wavelet domain downsampling-based compression scheme, we establish an enhanced low bit-rates coding framework by making...
A new analysis method was suggested based on the numerical solutions of the 3-dimensional flow field to analyze accurately the strength of impeller in the flat hydrodynamic torque converter for passenger car. The 3-dimensional flow govern equations were solved numerically by means of a computational fluid dynamics (CFD) software, and on the basis of the obtained numerical solution of the flow velocity...
A transgenic strain of the nitrogen-fixing filamentous cyanobacterium Anabaena PCC 7120 protected expressed -endotoxin proteins of Bacillus thuringiensis subsp. israelensis from damage inflicted by UV-B, a sunlight component that penetrates Earths ozone layer. This organism, which serves as a food source to mosquito larvae and could multiply in their breeding sites, may solve the environment-imposed...
