  • Patent number: 9882873
    Abstract: Systems and methods for MAC address allocation for virtual machines. An example method may include: initializing a virtual machine, determining that a network identifier has not been assigned to the virtual machine, in view of a determination that a network identifier has not been assigned to the virtual machine, transmitting, via a network, a network identifier request, receiving, via the network, one or more data packets, processing, by a processing device, the one or more data packets to identify a network identifier directed to the virtual machine, and assigning the network identifier to the virtual machine.

  • Publication number: 20170232245
    Abstract: The present invention provides a method for activating a pro-drug in vivo comprising the steps of: (a) administering a pro-drag to a subject; (b) locating a target site which has been at least partially dosed with the pro-drug at a predetermined concentration; and (d) exposing the target site to X-ray radiation. The step of exposing the target site to X-ray radiation is characterized by providing a converging X-ray of a controllable waist, substantially uniform at the target site, sufficient to convert the pro-drug to an active drug, whilst the X-ray photon dosage at the target site is higher than the X-ray photon dosage at an adjacent non target site.

  • Publication number: 20170032503
    Abstract: Images are processed to compensate for rolling shutter effects. A pair of images are registered. A set of pixel rows in the first image and a corresponding set of pixel rows in the second image are obtained. A parametric model is generated characterizing a transformation between pixels in the set of pixel rows in the first image with pixels in the corresponding set of pixel rows of the second image. Using the generated parametric model, the set of pixel rows in the second image is warped with respect to the set of pixel rows in the first image, reducing rolling shutter effects.

    Abstract: A computer-implemented system, method and computer readable medium to generate graphical visualizations corresponding to a data set populated in a web-based document, such as a spreadsheet. The spreadsheet is accessible in an interne or cloud-based system, and enables users to automatically create graphical visualizations or representations based on recommendations by a spreadsheet application. The graphical visualizations may be automatically ranked such that the system provides the recommendations to the user for display. Automatic ranking is accomplished, for example, by determining data types from identifying column type, differentiating column types, and extracting data sets having attributes corresponding to various graphical visualizations.
