  • Publication number: 20170247359
    Abstract: A process for the preparation of canagliflozin. The process may be effectively implemented on an industrial scale. Several compounds useful as intermediates for the synthesis of canagliflozin (Formula 4, Formula 4a, Formula 4b and Formula 5) are also disclosed. The process involves the reduction of the compound of formula 3 in the presence of a metal hydride and an organic solvent to obtain the compound of formula 4, converting this into a compound of formula 5 which in turn is converted into canagliflozin.

  • Publication number: 20170228453
    Abstract: Photograph organization based on facial recognition is described. In one or more embodiments, a photograph organization module obtains multiple photographs having images of faces and recognizes the faces in the multiple photographs. The module builds a population by attempting to distinguish individual persons among the faces in the multiple photographs, with each person of the population corresponding to a group of multiple groups. After a first pass through the faces, the population includes a number of duplicative persons. With a second pass, the photograph organization module reduces the number of duplicative persons in the population by merging two or more groups of the multiple groups to produce a reduced number of groups. The merging is performed based on comparisons of the faces corresponding to the two or more groups. The multiple photographs are organized based on the reduced number of groups. Organization can include tagging or displaying grouped photographs.

  • Publication number: 20140198793
    Abstract: A method, system and non-transitory computer-readable medium for forwarding data packet traffic in a point multi-point link aggregation using a link selector data table. A data packet is received at a device having a point multi-point link aggregation comprising a plurality of physical links. It is determined whether data extracted from the received data packet can be matched to one of a plurality of records in a link selector data table, where each record comprises data to identify a communication flow and data to identify one of the physical links, each record being generated from a data packet sampled in a transmission coming to the device along ones of the physical links. The received data packet is forwarded on the physical link identified by the one record, where the extracted data is matched to one of the plurality of records.

  • Publication number: 20120219727
    Abstract: The formation of a barrier layer within individual channels or cavities of a microfluidic device is described. The barrier layer is effected through a gas phase deposition process, desirably implemented in a plasma environment using a gas plasma reactor. Judicious selection of a precursor compound used within the gas plasma reactor can provide for generation of a layer on the individual surfaces. Desirably the surface or barrier layer is generated through the chemical adsorption of a metalloid oxide such as a silicon oxide layer on the surface of the individual channels or cavities.
