  • Patent number: 11934290
    Abstract: Certain aspects involve providing automated performance monitoring of statistical models. For example, a processing device is used for performing a statistical analysis on information in an archive to extract historical data, scores, and attributes. The processing device calculates performance metrics based at least in part on the historical data, scores, and attributes. The processing device pre-calculates summary performance data based at least in part on the performance metrics. The summary performance data is stored in files with predefined layouts, which are stored in a non-transitory, computer-readable medium. Segmented data is presented from a file to a user through a graphical user interface (GUI). In some aspects, various reports of the segmented data are presented interactively by detecting a selection by the user of a segmentation and displaying the corresponding segmented data.

  • Publication number: 20140102254
    Abstract: Disclosed is a method suitable for efficiently producing silver nanowires with high aspect ratio. In this method, silver nanowires with aspect ratio of more than 300 and purity of more than 80% are produced through an acid compound mediated microwave-assisted wet chemistry method. Such silver nanowires are especially suitable for the application in the flexible transparent electrodes, as they can simultaneously improve the electrical conductivity and transparency.

  • Patent number: 8623242
    Abstract: Disclosed is a method suitable for large-scale producing silver nanostructures including nanoparticles and nanowires with high crystallization and purity in a short period of time. In this method, silver particles with mean diameter less than 200 nm and silver nanowires with length in micrometers are produced through a microwave-assisted wet chemistry method. Tens to hundreds grams of silver nanoparticles and nanowires are obtained in minutes by microwave irradiation treatment to a precursor pre-made by highly concentrated silver salt solution and other additives. These silver nanoparticles and nanowires have good dispersibility and are ideal for forming conductive adhesives.
