摘要： The present invention relates to a method for preparing graphene oxide by cutting an end face of a 3-dimensional carbon-based material by electrochemical oxidation and the graphene oxide prepared by the method. The method comprises connecting a piece of a 3-dimensional carbon-based material as an electrode and another piece of a 3-dimensional carbon-based material or inert material as another electrode to the two electrodes of a DC power supply. A working face of one piece of 3-dimensional carbon-based material contacts the surface of an electrolyte solution, and the two pieces are electrified for electrolysis, during which the working face is between -5 mm below and 5 mm above the surface of the electrolyte solution. The graphite lamella on the end face of one piece of the 3 dimensional carbon-based material used as an electrode is expansion-exfoliated and cut into graphene oxide by electrochemical oxidation, to obtain a graphene oxide-containing electrolyte solution.

摘要： The present invention relates to a method for preparing graphene oxide by cutting an end face of a 3-dimensional carbon-based material by electrochemical oxidation and the graphene oxide prepared by the method. The method comprises: connecting a piece of a 3-dimensional carbon-based material as an electrode and another piece of a 3-dimensional carbon-based material or inert material as another electrode to the two electrodes of a DC power supply respectively, wherein an end face of at least one piece of a 3-dimensional carbon-based material serves as the working face and is positioned in contact and parallel with the liquid surface of an electrolyte solution; then electrifying the two pieces for electrolysis, during which the working zone for the end face serving as the working face is between −5 mm below and 5 mm above the liquid surface of the electrolyte solution; and intermittently or continuously controlling the end face within the working zone, such that the graphite lamella on the end face of the at least one piece of the 3-dimensional carbon-based material as an electrode is expansion-exfoliated and cut into graphene oxide by electrochemical oxidation, to obtain a graphene oxide-containing electrolyte solution. The method has a higher expansion-based exfoliating and cutting ability by oxidation, and can produce high-quality graphene oxide having fewer layers and more uniform particle-size distribution with low energy consumption and no contamination.

摘要： Systems and methods provide a parameterized scheduling system that incorporates end-user application awareness and can be used with scheduling groups that contain data streams from heterogeneous applications. Data packets are analyzed at multiple protocol levels to detect characteristics associated with communicating the packets. The data packets are filtered so that detecting the characteristics is efficiently performed. The detected characteristics can be used for scheduling transmission of the packets. The detected characteristics can be used to dynamically change scheduling parameters. The dynamic scheduling parameters can maximize user Quality of Experience (QoE) in response to recurring network patterns, one-time events, application characteristics, protocol characteristics, device characteristics, service level agreements, or combinations thereof. Scheduling parameters may also incorporate notions of “duration neglect” and “recency effect” in an end-user's perception of video quality in order to manage video traffic during periods of congestion.

摘要： Automatic detection of the virtual circuit setting and encapsulation type of a DSL line. A DSL modem determines the correct virtual path identifier (VPI) and virtual channel identifier (VCI) by sending OAM loopback requests to different VPI/VCI pairs until a valid loopback reply is received. PPPoA encapsulation is detected when a valid reply is received to a PPP LCP configuration request or echo request. PPPoE encapsulation is detected when a valid reply is received to a PPP LCP termination request or a PPPoE discovery offer (a PADO packet) is received in response to a PPPoE discovery initiation request (a PADI packet).
