  • Publication number: 20160203424
    Abstract: The present disclosure is related to methods, systems, and machine-readable media for information technology (IT) cost calculation in a software defined data center. A cost of infrastructure IT objects in a software defined data center can be calculated. The infrastructure IT objects can be mapped to an IT service construct over time, during runtime of the infrastructure IT objects. A portion of the cost of the infrastructure IT objects can be allocated to the IT service construct according to the map. A non-infrastructure IT cost can be allocated to the IT service construct. A total cost of the IT service construct can be calculated based on the allocations.

  • Publication number: 20150228866
    Abstract: Certain dithio-compounds have been found to be superior capping ligands for quantum dot (QD) nanoparticles. Example dithio-ligands include dithiocarbamate ligands. These strongly binding ligands are capable of coordinating to both positive and negative atoms on the surface of the nanoparticle. The ligands are bi-dentate and thus their approach to the QD surface is not as sterically hindered as is the approach of mono-dentate ligands. These ligands can therefore completely saturate the QD surface.

  • Patent number: 8190715
    Abstract: A storage area network push install performs SAN agent installation on a plurality of hosts according to a host install list. The target hosts may employ different operating systems, or platforms, and the installer selectively copies an install kit corresponding to the operating system on the target host The install kit includes an agent specific install script for identifying agent specific parameters on the target host. The installer initiates and remotely responds to the execution of the install script, or configuration script, in lieu of manual intervention by an operator, to provide the agent specific parameters for the agents being installed on the target host. The execution of the install script generates an agent initialization file for installing the agents in the appropriate locations on the target system. The agent initialization file establishes folders for locating the agent executable files and associated support files, as well as other runtime parameters.

  • Patent number: 8007757
    Abstract: A method of synthesizing nanostructures. In one embodiment, the method includes the step of heating a reaction mixture at an elevated temperature, T, for a period of time effective to allow the growth of desired nanostructures. The reaction mixture contains an amount, P, of a carboxylate salt and an amount, L, of a fatty acid ligand, defining a molar ratio of the fatty acid ligand to the carboxylate salt, ?=L/P, and a hydrocarbon solvent. The reaction mixture is characterizable with a critical ligand protection, ?, associating with the chemical structure of the carboxylate salt such that when ?<?, the reaction mixture is in a limited ligand protection (LLP) domain, and when ?>?, the reaction mixture is in a sufficient ligand protection (SLP) domain.

  • Patent number: 7668877
    Abstract: A system and method for providing a canonical query expression employable by a plurality of application tasks which may be invoked by a SAN management application avoids successive regeneration of extensive queries Each of the application tasks employs the canonical form of the same query, allowing multiple reports and actions to be invoked without reentry of the query by the user. In this manner, a user need not repeat the query entry for each invocation of a report or task. Rather, the canonical query form is provided to each application task for which a report or action is requested. Each of the application tasks, therefore, employs the canonical query expression. The canonical form defines a set of identifiable portions of a syntactical expression. The application tasks invoke some or all of the portions of the query expression derived from the initial syntax. Users or operators invoke the application tasks for providing a report, action, or other result.

  • Patent number: 7531149
    Abstract: A general, reproducible, and simple synthetic method that employs readily available chemicals permits control of the size, shape, and size distribution of metal oxide nanocrystals. The synthesis entails reacting a metal fatty acid salt, the corresponding fatty acid, and a hydrocarbon solvent, with the reaction product being pyrolyzed to the metal oxide. Nearly monodisperse oxide nanocrystals of Fe3O4, Cr2O3, MnO, Co3O4, NiO, ZnO, SnO2, and In2O3, in a large size range (3-50 nm), are described. Size and shape control of the nanocrystals is achieved by varying the reactivity and concentration of the precursors.

  • Patent number: 7284011
    Abstract: An agent generates a multidimensional database including file object characteristics, also known as a datacube, on each of a plurality of hosts, and employs a common server for aggregating each of the smaller datacubes into a collective datacube, or multicube, representative of all of the smaller datacubes from each of the hosts. Each individual host, therefore, contributes only a portion of the larger multicube and therefore processes and stores only the multicube portion of the file objects it represents. Each of the smaller datacubes is a potentially inclusive form representative of the entire multicube, however occupies a much smaller space due to the sparsity of storing only a subset of file object entries. Each of the hosts transmits a respective datacube to an aggregation server (aggregator) operable to aggregate, or sum, each of the datacubes from the plurality of hosts into the aggregate multicube.
