    • An activatable functionalised Nth generation dendrimer having: a core comprising a first monomer having at least two carboxylic acid functional groups; and N successive generations, where N=0 to 10, wherein each generation comprises: a second monomer having at least two alcohol functional groups, wherein at least one alcohol group is bonded to a carboxylic acid group of the first monomer of the prior generation, and an additional first monomer attached to a second alcohol function group of said second monomer of that generation; and the final generation having attached thereto at said second alcohol functional group of said second monomer, a moiety having a dicarboxylic acid functional group, activatable by treatment with a carboxylic acid activating reagent such that reactivity of the carboxylic acid functional group is increased. The dendrimer, when activated, may be used in applications such as polymer crosslinking and/or nanoshell production.

    • An auction method is operable in a first computing device that is arranged to communicate with a plurality of second computing devices across a network, each of the second computing devices being controlled by a respective party. The auction method comprises, at the first computing device, generating a request for an offer comprising at least one negotiable parameter, the request being sent to a plurality of parties participating in the auction. The first computing device is responsive to a respective offer being received from a plurality of the parties, each offer comprising a value for each of one or more parameters including the at least one negotiable parameter, to identify a current best offer by combining the parameter values to provide a ranking value for each offer. Responsive to the current best offer failing to be identified as a successful offer, a request for a better offer is sent to at least some of the parties.

    • A method for determining clock skew in a packet-based telephony session is disclosed. A telephony device receives RTCP SR packets from a remote telephony device transmitting RTP packets in a telephony session. Each control packet includes an NTP time-stamp and a RTP time-stamp. The device determines from two or more of the received SR packets a first relative rate of a remote media card clock to the remote system clock rate. Further, the device determines from two or more transmitted RTCP SR packets, a second relative rate of a local media card clock to the local system clock rate. The device can then be adjusted to take into account the first and second relative rates for optimum buffer management and to more accurately adjust the quality of a session based on one-way packet delay.
    • 公开了一种用于确定基于分组的电话会话中的时钟偏差的方法。 电话设备从电话会话中发送RTP分组的远程电话设备接收RTCP SR分组。 每个控制分组包括NTP时间戳和RTP时间戳。 设备从两个或更多个接收的SR分组确定远程媒体卡时钟的第一相对速率与远程系统时钟速率。 此外,设备从两个或更多个发送的RTCP SR分组确定本地媒体卡时钟的第二相对速率到本地系统时钟速率。 然后可以调整设备以考虑用于最佳缓冲器管理的第一和第二相对速率,并且基于单向分组延迟更准确地调整会话的质量。

    • A method for the quantitative characterization of a seabed sediment composition and a seabed's layered subbottom structure from at least one normal-incidence, single-channel reflection acoustic amplitude time series seismogram is disclosed. The method detects a plurality of reflections from subbottom interfaces in said seismograms, determines the traveltime, the polarity and the reflectivity of each detected reflection, determines the intrinsic attenuation of the sediment layer between pairs of adjacent reflections, and determines the acoustic properties, layer thicknesses and material properties of the seabed's layered subbottom structure as a function of said traveltimes, polarities and reflectivities of the detected reflections and said intrinsic attenuation of the sediment layer between pairs of adjacent reflections. A forward model describing the physical relationship between the material properties and the acoustic properties of seabed sediments is also disclosed.
