Media acceleration for virtual computing services
Streaming media is problematic for thin clients using remoting protocols like RDP that were never designed to handle the volume of data associated with multimedia. The result is large demands on the host computer and thin client CPU and excessive bandwidth on the network, which results in a poor display quality. A process running on a host computer detects an existing multimedia acceleration channel to a thin client and also identifies unaccelerated media streams like Adobe Flash. The unaccelerated content is automatically re-encoded using a codec format supported by the thin client acceleration channel. This results in a significant improvement in the quality of the streaming media displayed on the thin client and overall reductions in host CPU load, network bandwidth and thin client CPU load. No additional software is required on the thin clients to support new media types including Adobe Flash. |

Solar cells fabricated from p-n junctions of boron nitride nanotubes alloyed with carbon are described. Band gaps of boron nitride carbon alloys are tailored by controlling carbon content in the boron nitride nanotubes. High efficiency solar cells can be fabricated by tailoring the band gap of boron nitride carbon alloy nanotubes, and using these nanotubes for fabricating solar cells u. Because boron nitride carbon alloy nanotubes are transparent to most wavelengths of light, the wavelengths not converted to electrons (i.e., absorbed) at a first p-n junction in a solar cell will pass through the stack to another p-n junction in the stack having a different band gap. At each successive p-n junction, each of which has a different band gap from the other p-n junctions in the stack, more wavelengths of light will be converted into electricity. This dramatically increases the efficiency of solar cells. |

The system uses a plurality of predictor variables stored in a plurality of data sets, to automatically create a business decision analytic model. The system includes a processor configured to process the data sets and determine the total number of records present in each of the data sets and the number of columns containing only numerical values. The processor selects a column containing only numerical values, from a dataset under consideration, and counts the number of unique numerical values in the selected column, and the total number of records present in the selected column. The two counts are compared and the selected column is transformed using a non-linear transformation to obtain a column of transformed values. The transformed values and corresponding time stamps are utilized for the purpose of model generation. |

Systems, apparatus and methods for labeling, packaging, and tracking surgical articles
Surgical articles, such as sponges, are provided in a pack which contains individual surgical articles having UHF RFID or other electronic labels which provide both (a) unique identification information for each article as well as (b) unique identification information for all articles in the pack. Prior to the surgical procedure, the labels are scanned and the identification information for all articles in the pack uploaded to a processor to create a list of available individual surgical articles. At the end of the surgical procedure, the surgical articles are collected and the electronic labels read and compared to the initial list to determine if there are any unaccounted individual surgical articles. The UHF RFID tag may then be used to determine a location of the unaccounted article outside the patient's body. |
