  • Publication number: 20110261349
    Abstract: A method for providing images using a multimodal nonlinear optical microscope is disclosed. The method includes providing a foundation femtosecond laser beam, generating a first femtosecond laser beam and a second femtosecond laser beam corresponding to the foundation femtosecond laser beam, combining the first femtosecond laser beam and the foundation femtosecond laser beam to generate a first combination femtosecond laser beam, and generating a coherent anti-Stokes Raman scattering (CARS) signal based on the first combination femtosecond laser beam. A multimodal nonlinear optical microscopy platform is also disclosed.

  • Publication number: 20110040786
    Abstract: A method is provided for handling synchrophasor measurements relating to an electrical power system. The method includes: (a) acquiring a plurality of synchrophasor measurements containing data representing at least one power system event; (b) inserting and storing the event related synchrophasor measurements in a database as a partitioned binary large object (BLOB); (c) reading and transferring the synchrophasor measurements related to a user selected current or historical event from the database to a client computer partition by partition; and (d) processing the event data at the client computer on a partition-by-partition basis such that the client computer will be able to start a replay of the event replay as soon as processing of the first partition of the event BLOB data is completed.
