20130323730 | METHOD FOR DETERMINING PLOIDY OF A CELL - A method for determining the ploidy of a test genome is provided. In some embodiments, the method may comprises: a) obtaining a plurality of ratios for polymorphisms that are distributed throughout a test genome, wherein each of the ratios is a ratio of the measured copy number of uncut allele in a polymorphic site relative to the measured copy number of the uncut allele in the reference sample; b) taking the log of the ratios and plotting a distribution of the reference corrected log ratios of the SNP probes; and c) determining the ploidy of said the genome based on the number of peaks in that distribution. | 12-05-2013 |

20120030739 | METHOD AND APPARATUS FOR SECURITY OF MEDIUM INDEPENDENT HANDOVER MESSAGE TRANSMISSION - A method and an apparatus for securing media independent handover message transportation are provided. The method for securing media independent handover message transportation, include: performing an authentication procedure by a terminal with an access router to generate a master session key; transmitting the generated master session key and address information of the terminal to an information server by the access router; generating an information server key to be used in transmitting and receiving a message by the information server with the terminal using the received master session key and the address information of the terminal; and forming a secure channel by the terminal and the information server using the generated information server key. Since a key formed at a layer 2 is used in an MIH authentication step being a layer 3 not to repeatedly create a secure key, a security procedure may be rapidly performed. | 02-02-2012 |

20110080952 | SYSTEM AND METHOD FOR ADAPTIVE INTRA REFRESH RATE SETTING IN A VIDEO ENCODER - A system and method for adaptive intra refresh rate setting for each video frame in a video encoder is disclosed. In one embodiment, a video encoding method includes computing channel induced distortion values at multiple intra refresh rates for a coded video frame as a function of channel loss and spatiotemporal content, computing source coding distortion values at the multiple intra refresh rates for the coded video frame as a function of the spatiotemporal content and an operating bit-rate, selecting an intra refresh rate value for one or more video frames subsequent to the encoded video frame as a function of the sum of the corresponding computed channel induced distortion values and the source coding distortion values, and encoding the one or more video frames using the selected intra refresh rate value. | 04-07-2011 |

20080247469 | METHOD AND DEVICE FOR TRACKING ERROR PROPAGATION AND REFRESHING A VIDEO STREAM - A method and device for tracking error propagation and refreshing a video stream is provided. The proposed subject matter comprises of an error propagation tracking method that works in the sub-sampled domain to reduce computational cycles and memory bandwidth. Further, the tracking based update of the error propagation metric is done differently for static and non-static regions to avoid unnecessary refresh of static areas. Through suitable thresholding of the metric at a macroblock (MB) level, a set of refresh MBs are selected for each frame. These refresh MBs are coded either as an intra MB or as an inter MB that is predicted from one or more reliable reference frames (—frames that are known to be available at the decoder with negligible errors—). Such inter coding of refresh MBs improves the compression efficiency when compared to pure intra coding of refresh MBs. Further, variants to the threshold selection are presented that result in temporally uniform distribution of the number of refresh MBs and a strict refresh scheme wherein all MBs are guaranteed to be with negligible errors following a packet loss within a committed refresh period. In addition, to using the error propagation metric, spatial connectivity to already chosen refresh MBs is used in the selection of additional refresh MBs within a frame and across frames; this reduces the rate of error propagation due to part of a macroblock predicting from older, erroneous neighboring MBs and in turn requiring more refresh MBs on the average per frame. | 10-09-2008 |

20110066847 | Just In Time Trust Establishment and Propagation - Trust relationships in an online service system are established at a domain level, and propagated to components of domains as they attempt cross domain communication. In attempting to communicate across domains, a first component in a first domain attempts to validate a certificate of a second component in a second domain. Where the attempt to validate the certificate indicates that a trust relationship does not exist between the first component and the second domain, the first component determines whether a domain level trust relationship exists between the two domains. The first component propagates the trust status between the first and second domains to itself. If there is an existing trust relationship between the first and second domains, the first component validates the certificate of the second component in response. The second component executes the same process to complete the connection. | 03-17-2011 |

20160044609 | REPORTING USER EQUIPMENT TRANSMISSION POWER HEADROOM (UPH) OF A SECONDARY UPLINK CARRIER - The present disclosure presents a method and an apparatus for reporting a user equipment (UE) transmission power headroom (UPH) of a secondary uplink carrier at the UE. For example, the method may include activating the secondary uplink carrier upon receiving a message from a base station in communication with the UE to activate the secondary uplink carrier, determining whether the UE has data available for transmission from the UE to the base station, computing a UPH value of the secondary uplink carrier in response to determining that the UE has data available for transmission, and transmitting the computed UPH value to the base station. As such, timely reporting of a secondary uplink carrier UPH to improve performance may be achieved. | 02-11-2016 |
