Abstract: A method for handling communication data involving identifying available resources for applying compression tasks and estimating a throughput reduction value to be achieved by applying each of a plurality of different compression tasks to a plurality of media items. A cost of applying the plurality of different compression tasks to the plurality of media items is estimated. The method further includes finding an optimization solution that maximizes the throughput reduction value over possible pairs of the compression tasks and the media items, while keeping the cost of the tasks of the solution within the identified available resources and providing instructions to apply compression tasks according to the optimization solution.

Abstract: A system for compressing and decompressing sequential records to store only those parts of a record which differ from the previous record. The system for compressing includes a bit map which indicates which parts of a record if any are the same as the preceding record. The system enables compression and decompression of records without the need to access additional blocks and perform additional disk I/Os to obtain the expanded version of a given compressed record.

Abstract: Hard, infusible, discrete beads of crosslinked copolymer are prepared by free-radical catalyzed polymerization of a monomer mixture in aqueous dispersion wherein a minor amount of a modifier, specifically an organic compound containing acetylenic or allylic unsaturation having the ability to moderate the rate of polymerization, is incorporated in the monomer mixture. Ion exchange resins having improved mechanical strength are obtained by attaching functional groups to the copolymer.
