JPEG2000, a newly developed international standard for still image compression. It can provide superior objective and subjective image quality and can reduce file size by 40% compared with JPEG while retaining the same visual quality.Rate control or rate allocation is of great necessity to control t.....

This invention discloses an alternative approach of electrically tuning silicon-based waveguide-coupled microresonators that employs photoaligned liquid crystals as cladding layers. Planar optical microresonators that partially confine light and support sharp optical resonances have long been demon.....

Electrorheological(ER) fluids are of high interest because potentially they can provide simple, quiet, and fast interfaces between electrical controls and mechanical systems. However, a problem with ER fluids to date is that the yield strength is too low for many practical applications. The main dra.....
