The present invention relates to the construction of hyperbranched polytriazoles and linear and hyperbranched poly(aroyltriazole)s by Huisgen 1,3-dipolar polycycloaddition. The polymers were prepared by A2 + B3 methodology to avoid self-polymerization during monomer preparation and storage. A new cl.....

At the internet age, transmittal of video signal in digital form is very common. Among various video compression standards or processes established, Discrete cosine transform (DCT)- based block transform coding is one of the frequently used coding techniques for compression of still image. This meth.....
