Motion-Compensated Spatio-Temporal Wavelet Compression Of Video Data With Optimised Permutation Of The Frames

In video encoding, the video frames are spatio-temporally filtered for reduction of spatial and temporal redundancy before they are entropy encoded. Known filtering schemes consider temporally successive frames and are static. It is probable but not necessary that successive frames are most efficient to encode. Therefore, a plurality or all possible frame order permutations are considered for a group of frames (GOP) and evaluated based on a global criterion, which is the sum of local criterion values computed over successive subsets of permuted frames. The local criterion value is deduced from motion estimation processed on each considered set of frames. The best ordering is chosen as the one that minimizes the global criterion value.

The spread of HIV has caused and continues to cause serious health problems throughout the world. A number of HIV inhibitory drugs have been developed that currently are used to combat the virus. These drugs have proven out to be effective in suppressing the virus, in particular when used in combination therapy. However no therapy is capable of completely eliminating the virus from the body.Several classes of HIV inhibitors at present are available and new ones are being explored. One such class is that of that of the non-nucleoside reverse transcriptase inhibitors (NNRTIs). This class comprises a number of drugs that are used in anti-HIV therapy while other NNRTIs are in various stages of development. One of these is the compound 4-[[4-[[4-(2-cyanoethenyl)-2,6-dimethylphenyl]-amino]-2-pyrimidinyl]-amino]-benzonitrile, also known as TMC278.

Process for control of molecular weight distribution in polymers

This invention provides a polymerization process for producing polymers with narrow molecular weight distributions. It comprises addition of monomer and initiator to a reaction vessel using a monomer feed profile and an initiator feed profile wherein the feed profiles are such that the ratio of monomer concentration to initiator concentration is determined in accordance with a polymerization kinetics relationship between a selected degree of polymerization and monomer concentration, initiator concentration, reaction temperature and a polymerization efficiency factor to obtain an approximately constant degree of polymerization for polymer produced during the polymerization process. The polymerization efficiency factor accounts for deviations from ideal kinetics relationships.
