Methods suitable for producing textured surfaces in surfaces of objects, by which the methods are able to achieve a desired three-dimensional surface topography and optionally a desired subsurface microstructure through the use of a controlled modulation machining technique. The methods include selecting a predetermined surface texture for a surface of a body, and then imposing a superimposed sinusoidal feed-modulation on a cutting tool so as to move the cutting tool in a feed direction relative to the body while machining the body with the cutting tool and generating a machined surface of the body. The surface texture of the machined surface is intentionally controlled by at least the modulation amplitude and the modulation frequency of the superimposed sinusoidal feed-modulation.

A HCPS (hierarchically clustered P2P streaming system) comprising peers grouped into clusters and hierarchies. The HCPS actively balances the uploading capabilities among clusters and executes an optimal scheduling algorithm within each cluster to ensure that system resources are optimally utilized. The HCPS comprises an architecture which can be used in practical applications, yet can achieve the streaming rate close to the theoretical upper bound.

The present invention discloses an FDD (Frequency Division Duplex) system based multi-user beamforming method and device. In the method, when two or more user terminals are at respective AOAs (Angles of Arrival), a transmit weight of a downlink signal of each user terminal is determined by using a null-widening algorithm, and the transmit weight is stored in a network side, the network side groups the user terminals based on AOA information reported by the user terminals, a corresponding transmit weight for the downlink signal of each user terminal in each group is selected based on the AOA information of the user terminals in the group, and the selected transmit weight is transmitted after multiplying it by a downlink data stream of the user terminal corresponding to the transmit weight.
