Abstract: Provided is a method for interference alignment applied to a multi-cell and multi-user Multiple Input Multiple Output (MIMO) system. The method includes that: a BS divides multiple users in a cell into a plurality of user groups, and notifies the multiple users of grouping information; and when one of the plurality of user groups is interfered by a neighbor cell, users in the one of the plurality of user groups cooperate with each other to perform interference alignment. The disclosure also provides a pre-coding method and system based on interference alignment. The disclosure, by means of grouping and cooperation of the users and designing of a receiving matrix of each user, achieves the effect of interference alignment in a signal transmission space of the BS.

Abstract: A functionalised graphene oxide and a method of making a functionalized graphene oxide comprising: (i) oxidizing graphite to form graphite oxide wherein the graphene sheets which make up the graphite independently of each other have a basal plane fraction of carbon atoms in the sp2-hybridised state between 0.1 and 0.9, wherein the remainder fraction comprises sp3-hybridised carbon atoms which are bonded to oxygen groups selected from hydroxyl and/or epoxy and/or carboxylic acid; and (ii) exfoliating and in-situ functionalizing the graphite oxide surface with one or more functional groups such that fictionalization of the surface is effected at a concentration greater than one functional group per 100 carbon atoms and less than one functional group per six carbon atoms. The functionalized graphene oxide is dispersible at high concentrations in appropriate solvents without aggregating or precipitating over extended periods at room temperature.

Abstract: Technologies are generally described for exploiting program phase behavior to duplicate most recently and/or frequently accessed tag entries in a Tag Replication Buffer (TRB) to protect the information integrity of tag arrays in a processor cache. The reliability/effectiveness of microprocessor cache performance may be further improved by capturing/duplicating tags of dirty cache lines, exploiting the fact that detected error-corrupted clean cache lines can be recovered by L2 cache. A deterministic TRB replacement triggered early write-back scheme may provide full duplication and recovery of single-bit errors for tags of dirty cache lines.
