  • Publication number: 20100094921
    Abstract: A system and method are provided for peer-to-peer distributed file storage in a network of connected clients. The method transmits data file peer-storage information from a first peer node to a network-connected backup manager. The backup manager creates a mapping plan, for mapping data file segments to a peer group, which typically includes a plurality of network-connected peer nodes. The backup manager transmits the mapping plan to the first peer node. The first peer node distributes the data file segments to the peer group in accordance with the mapping plan, for storage in tangible memory media. Typically, the first peer node accepts a data file and encrypts the data file. In one aspect, the backup manager creates a mapping plan for distributing (n+x) erasure-coded segments. After receipt of the mapping plan, the first peer node creates the (n+x) erasure coded file segments in preparation for distribution.

  • Publication number: 20090312856
    Abstract: A method for determining the task load in real-time. The method takes a difference in real-time between a first count value from a free running counter prior to a task executing, and a second count value after the task stops running. The task load may then be determined by using an accumulator to accumulate the difference between the first count value and the second count value over a reference interval and dividing the sum by a configurable reference interval. The individual task load computed in real-time may be used in scheduling an audio task.

  • Patent number: 6858588
    Abstract: The present invention relates to a novel nitrile glycoside of Formula I named NIAZIRIDIN and to analogues and derivatives thereof. The present invention also relates to a process for the isolation of a novel nitrile glycoside of Formula I below named NIAZIRIDIN and its derivatives and analogues by bioactivity-guided fractionation from the pods of Moringa oleifera. The present invention particularly relates to the bioenhancing activity of the novel nitrile glycoside of Formula I below named NIAZIRIDIN and its derivatives and analogues in enhancing bioactivity of commonly used antibiotics such as rifampicin, tetracycline and ampicillin against Gram (+) and (?) bacteria. The biomolecule also enhances the absorption of drugs, vitamins and nutrients through the gastro-intestinal membrane increasing their bio-availability. Therefore niaziridin can be used in combination therapy with drugs and nutrients resulting in reduced drug associated toxicity, reduced cost and duration of chemotherapy.

  • Patent number: PP15595
    Abstract: A new and distinct variety of Cymbopogon commutatus grass is provided. The new variety was discovered during a mass selection program that was carried out in India in a cultivated area, and offers significant advantages over a typical plant of the species. More specifically, the new variety exhibits superior drought tolerance, a vigorous perennial growth habit, and lighter green leaves than typically exhibited by the species. The plant produces an essential oil having an enhanced geraniol and geranyl acetate content that is useful to form perfumes and in flavor applications. Asexual reproduction can be readily carried out by the rooting of slips.
