  • Publication number: 20150278076
    Abstract: A device may be configured to receive, from a first device, first test scripts for testing an application. The first test scripts may include information for reproducing interactions with the application on the first device. The device may generate second test scripts, for testing the application on a second device, that reproduce the interactions with the application on the second device. The second test scripts may be generated based on the first test scripts and mapping information that maps resources of the first device to resources of the second device. The first device and the second device may be different device types. The device may provide the second test scripts to the second device. The device may receive and store test results of executing the second test scripts on the second device that indicate results of reproducing the interactions on the second device.

  • Patent number: 9084989
    Abstract: Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PRFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.

  • Patent number: 9011309
    Abstract: An electromagnetic radiation activated device comprises a property changing material and at least one functionalized fullerene that upon irradiation of the functionalized fullerenes with electromagnetic radiation of one or more frequencies a thermally activated chemical or physical transformation occurs in the property changing material. The thermal activated transformation of the property changing material is triggered by the heating or combustion of the functionalized fullerenes upon their irradiation. The device can include a chemical agent that is embedded in the property changing material and is released when the material is heated by the functionalized fullerenes upon irradiation.

  • Patent number: 8986516
    Abstract: A method to release hydrogen from a material comprising hydrogen fixed fullerenes involves irradiating the hydrogen fixed fullerenes with electromagnetic radiation of sufficient intensity to release hydrogen rapidly upon irradiation. The intensity of the irradiation and/or the area of irradiation can be adjusted to control the rate and extent of hydrogen release. The hydrogen depleted material comprising hydrogen fixed fullerene can be hydrogenated to regenerate the material.

  • Patent number: 8974644
    Abstract: Electromagnetic irradiation of functionalized fullerenes in an oxygen-free environment induces conversion of the functionalized fullerenes to carbon nanotubes, carbon nanohorns, carbon onions, diamonds and/or carbon schwarzites. The carbon nanotubes can be multi-wall carbon nanotubes. Advantageously, the subject invention can be used for in-situ synthesis of carbon nanostructures within a matrix to form a carbon nanostructure composite, where positioning of the carbon nanostructures is controlled by the manner of dispersion of the functionalized fullerenes in the matrix. Carbon nanotube comprising features, such as electrical connects, can be formed on a surface by irradiating a portion of a functionalized fullerene coating with a laser beam.

  • Patent number: 8839031
    Abstract: Data consistency between a primary virtual machine and a recovery virtual machine may employ a resync engine to detect differences in data blocks stored on both virtual machines. For example, the resync engine may calculate a signature (e.g., hash value) for a primary data block and a corresponding signature for a recovery data block, and compare the signature and the corresponding signature to identify a difference between the primary data block and the recovery data block. In some instances, by identifying a difference between the primary data block and the recovery data block, a data block (e.g., primary data block or recovery data block) may be identified to be transferred from a virtual machine to another virtual machine.

  • Patent number: 8373139
    Abstract: Functionalized fullerenes, when excited at any of a broad range of wavelengths in an oxygen free environment, undergo luminescence. The oxygen sensitive luminescence of functionalized fullerenes is used for numerous applications including oxygen detection; irradiation induced healing of polymeric materials; and phosphors for optical location and display applications. The degradation of the functionalized fullerenes allows for the detection of oxygen by diminished luminescence when the fullerenes are exposed to an irradiation source, such as a laser beam, in the presence of oxygen. The luminescence from a portion of a surface of a material with functionalized fullerenes allows for the location of the surface containing a functionalized fullerene target in the absence of oxygen or to heat the object in the area irradiated that is exposed to oxygen. The localized heating can be used to repair defects to a material containing the functionalized fullerenes.

  • Publication number: 20120054027
    Abstract: A network based advertisement system includes an optimizer configured to forecast a supply of opportunities, forecast a supply of guaranteed contracts, and forecast a supply of non-guaranteed contracts. Each opportunity represents a user visiting a webpage. Each guaranteed contract guarantees the matching of an advertisement to a number of opportunities. Each non-guaranteed contract guarantees a user event associated with an advertisement. The optimizer then generates a plan for matching contracts to opportunities based on the forecasted supply of opportunities, the forecasted supply of guaranteed contracts, the forecasted supply of non-guaranteed contracts, and an objective function that balances a group of parameters that define the representativeness of contracts, a cost associated with not serving non-guaranteed contracts, and performance objectives associated with contracts.
