It is very difficult to shield low frequency sound waves. This is mainly because in order to cause wave scattering or reflection, the usual wisdom is that the size of the scatterers must be on the order of the wavelength. Since low frequency sound has long wavelength, it follows that the shielding m.....

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.....

Zeolites are microporous crystalline aluminosilicate molecular sieve that have pore sizes ranging from about 0.3 to 1 mm. Due to their uniform, molecular-sized pores, they can separate molecules based on their size, shape and polarity. They can therefore act as ''molecular sieves''. Membranes made o.....
