Method of and base station for controlling beam forming in a mobile cellular network

The invention concerns a method and a base station (21) for controlling beam forming in a mobile cellular network: Antenna units (212) of base stations (21) of a cluster of neighbored base stations (21) apply a respective beam pattern sequence on each sector of a cell served by the respective base station (21). The beam pattern sequence is selected from a respective predefined set of beam pattern sequences and each beam pattern sequence defines a sequence of beam subsets used for communication with mobile units (41, 42, 43, 44). One of the base stations (21) of the cluster which acts as trigger base station informs all neighbored base stations of the cluster of neighbored base stations (21, 22, 23, 24, 25, 26, 27) not to change their beam pattern sequences. The trigger base station (21) controls the antenna unit (212) of the trigger base station (21) to change the beam pattern sequence applied on the sectors of the cell and sequently apply two or more different beam pattern sequences of the predefined set of beam pattern sequences on the respective sector. The trigger base station (21) triggers one or more mobile units (41, 42, 43, 44) located in the cluster of neighbored base stations to calculate one or more signal quality parameters for currently applied beam pattern sequences of the trigger base station (21). The trigger base station (21) selects an optimal beam pattern sequence from the set of the predefined beam pattern sequences based on the one or more calculated signal quality parameters and the antenna unit (212) of the trigger base station (21) applies the optimal beam pattern sequence as a new beam pattern sequence on the respective sector.

Method and system for entropy decoding for scalable video bit stream

A method, program product and apparatus for decoding from a scalable bit stream the binarization results of a video sequence by selectively decoding syntax elements and avoiding redundancy in coding. The result is a decrease in the size of the compressed bit stream of an enhancement layer bit stream. One method includes determining whether a skipping flag in the base layer macro block of the video data is set, and decoding a skipping flag from an enhancement layer macro block of the video data, corresponding to the base layer macro block, only if the base layer macro block skipping flag is set. Another method includes determining which of a plurality of blocks in a base layer macro block contain zero coefficients, decoding an abbreviated coded block pattern (CBP) of an enhancement layer macro block, where the CBP includes a number of digits equal to the number of blocks in said base layer macro block containing only zero coefficients, and then generating a complete CBP for the enhancement layer based on the results of said decoding. Yet another method includes decoding a CBP value of a base layer macro block and differentially decoding a CBP value for an enhancement layer macro block relative to the CBP of the base layer macro block. An additional method includes determining the zero-value coefficients in a block of a base layer, decoding a coded block flag for a corresponding block in an enhancement layer, and determining, based on the value of said encoded block flag, whether any of the zero-coefficients become non-zero coefficients in said enhancement block.

Method for repairing a cold section component of a gas turbine engine

A method for forming a wear-resistant hardfaced contact area on the shroud section of a gas turbine engine blade. A predetermined contact area of a shroud section of a gas turbine engine blade is selectively coated with a high-density hardface coating material. The hardface coating material is capable of forming a diffusion boundary between the hardface coating material and the shroud section. A hot isostatic heat treatment process is performed to form the diffusion boundary between the hardface coating material and the shroud section to form a wear-resistant hardfaced contact area diffusion bonded to the shroud section. Depending on the coating process, and the necessity for doing so, the predetermined contact area can be masked off before the step of selectively coating. A sintering heat treatment can be perfomed before the step of performing the hot isostatic heat treatment to limit the occurrence bubbles on the surface of the hardface coating material after the isostatic heat treatment step. The sintering heat treatment may be performed at a temperature substantially the same as the temperature of the hot isostatic heat treatment. The hardface coating material may comprise an alloy with substantially no oxide forming constituents so as to avoid the formation of oxide inclusions in the coating material.

Aluminum-containing and sulfur-containing series gear steel smelting process

The invention discloses an aluminum-containing and sulfur-containing series gear steel smelting process. Liquid iron is required to contain 0.20-0.50% of Si, less than or equal to 0.035% of S, and less than or equal to 0.110% of P, and at a temperature T greater than or equal to 1250 DEG C; lime for an electric furnace and refining is required to contain greater than or equal to 90% of CaO and less than or equal to 1.2% of SiO2, and has the activity degree of greater than or equal to 300 and the granularity of 10-40mm; a low-silicon refining agent is required to contain greater than or equal to 45% and less than or equal to 55% of CaO, less than or equal to 2.0% of SiO2, and greater than or equal to 35% and less than or equal to 40% of Al2O3. The liquid iron hot charge ratio of the electric furnace reaches up to 90%; for LF refining, a first strong and later weak deoxidization manner is adopted; at the middle-late stages, a weak deoxidizer is adopted for furnace slag maintenance to realize further deoxidization. Meanwhile, deoxidization and S removal are performed, and then an S wire is fed to obtain a certain S content; in addition, the S wire is allowed to be fed only in more than 5 minutes after the denaturalization treatment of feeding a calcium-iron wire into VD liquid steel, and therefore, the formation of CaS inclusion in a clogging material at other water gap is prevented; and at last, the castability of the liquid steel is guaranteed while excellent structural properties of the steel product are obtained, and the purity of the liquid steel is improved.

Constraint based routing with non-transitive exceptions

In a multiple element network, a method and network element for providing a constraint based routing system to accommodate non-transitive exceptions. The method and network element receive a connection request for an end to end connection. The network element can select routing information having a pair of adjacent links associated with the multiple elements of the network, where each link of the pair of links has a shared network resource. The shared network resource is compared to a database of exception sets, the exception sets including at least one non-transitive exception predetermined from a plurality of network resources. The network element confirms whether the shared network resource of the selected pair of links is contained within the exception database. A router designs a pathway over the network for the end to end connection using the results of the shared network resource comparison, wherein inclusion in the pathway is inhibited for the shared network resource matching the predetermined exclusion set contained in the database. Accordingly, the list of exception sets is accessible by a constraint based routing algorithm as input to exclude the selected link pair of a pathway for the end to end connection over the network, if the shared network resource of the link pair is contained within the exception sets.
