Quality assessments in multiplexing

Considering low bit rate sources the quality of speech suffers mainly by a factor, such as quantization noise. Multiplexing efficiency is therefore, based upon the encoding sources bit rates. Lower the coding rates, better the efficiency but on the expense of quality. The quality in multiplexing is assessed by two means, objectively and subjectively.

An Empirical Investigation Of How To Increase User Engagement On Facebook Business Pages

With the raging trend of networking on social networking sites such as Facebook, almost all businesses are trying to reach their consumers using the social networking site.
