Processing Complex Aggregate Queries over Data Streams

Two key parameters for query processing over continuous data-streams are (1) the amount of memory made available to the on-line algorithm, and (2) the per-item processing timerequired by the query processor. The former constitutes an important constraint on the design of stream processing algorithms, since in a typical

Efficient Processing of Aggregates in Probabilistic Databases

While the need is there, the speed of processing aggregates over probabilistic data has to be comparable with the speed current system achieves when computing aggregates over non-probabilistic data. Should the former be much slower, the appeal of probabilistic processing is significantly diminished.

Mineral Processing Wastes User Guidelines Asphalt

Over the years, there have been numerous examples of the use of mineral processing wastes, notably waste rock and mill tailings, in asphalt paving applications. The current use of mineral processing wastes as aggregate in hot mix asphalt is not a common practice, due in great part to the relatively remote location of many sources of these wastes.

Removing Aggregates in Monoclonal Antibody Purification

First, aggregates may cause a decrease in product efficacy due to lowering the effective concentration of the drug product. Second, aggregates increase the risk of an immunogenic response in patients, including anaphylaxis. For these reasons, the removal of aggregates is a focus of downstream processing.
