  • Publication number: 20160234333
    Abstract: A system and method for joint dynamic interest request forwarding and dynamic cache placement and eviction and provided within the context of the Named Data Networking (NDN) architecture. The system and method employ a virtual control plane that operates on the user demand rate for data objects in the network, and an actual plane that handles Interest Packets and Data Packets. Distributed algorithms within the virtual plane achieve network load balancing through dynamic forwarding and caching, thereby maximizing the user demand rate that the NDN network can satisfy. A method of congestion control is also provided to achieve optimal network fairness using the VIP framework.

  • Publication number: 20160085316
    Abstract: Embodiments of the present invention discloses an input method of Chinese pinyin. The method comprises: obtaining an operation position and an operation duration of inputting a character through a character input platform; determining a combination of pinyin letters corresponding to the operation position according to mapping relationships between operation positions of the character input platform and character information; selecting a pinyin letter from the combination of pinyin letters corresponding to the operation position or selecting the combination of pinyin letters corresponding to the operation position as a character input through the character input platform according to mapping relationships between operation durations each corresponding to one of the operation positions of the character input platform and character information. The embodiments of the present invention further discloses a terminal.

  • Patent number: 8535830
    Abstract: The present invention relates to electrochemical storage devices, such as supercapacitors, batteries, etc., and more particularly to such devices that comprise an electrochemically active coaxial nanowire. The invention particularly concerns such devices in which the coaxial nanowire comprises an inner core of a transition metal oxide and an axially surrounding outer shell composed of an electroconductive organic polymer, such as poly(3,4-ethylenedioxythiophene) (PEDOT). The invention particularly relates to a facile method for achieving the self-assembly of such coaxial nanowires.
