A method of distributed control of a wireless mesh network without knowledge of global topology. The method includes: a station joining the network with any current member by propagating the join-request, or two meshes merging using the steps of: one mesh joining the other as a whole and then re-synchronizing its timing. The method further includes: first, each station periodically transmits a beacon; second, in response to a beacon being no longer detected, a station transmitting a bitmap of stations that it can still receive; third, each station responds by adding stations that it can receive with all of the bitmaps received from other members, and retransmitting the updated bitmap; fourth, after time for all stations to respond, all stations base current membership on the bitmap. The method further includes: determining sharable time slots that will not interfere with neighbors or other slot sharers, using and then releasing those slots.

In a model editing apparatus, a model transformation function transforms SM (source model) 0 into TM (target model) 0, and generates TDM (transformation dependency model) 0. Moreover, when an SM editor generates SM1 by updating SM0, the model transformation function transforms SM1 into TM1 and generates TDM1. When a TM editor generates TM0_n by editing TM0 independently of the change in SM0, a Change element registration function registers a difference Δ2 between TM0 and TM0_n in TDM0, thereby generating TDM0_n. Then, in response to a call, a merge function merges a difference Δ1 between TDM0 and TDM1 extracted by a Δ1 extraction function, and a difference Δ2 extracted from TDM0_n, according to prestored processing patterns.

The invention provides a method of preparing vitamin E acetate. The method includes the steps of: feeding hydrogen halide gas as a catalyst, supporting a metal halide and elementary metal on a molecular sieve to obtain a cocatalyst and a stabilizing agent, and performing a reaction to 2,3,5-trimethylhydroquinone diester (TMHQ-DA) and iso-phytol (IPL) to produce the vitamin E acetate (VEA). The method has high catalyst activity and has low corrosion on equipment, wherein the raw material is converted into the vitamin E acetate directly through one step. The product has good stability and the method is easy to carry out in industrial enlarged production.

A planned schematic for an electronic system is hierarchically divided into base-level schematic blocks which may be designed individually. In accordance with a plurality of sets of design requirements, variant overlays are designed for each base-level schematic block, each overlay including variant parameter values which may replace corresponding parameter values of the schematic blocks. The schematic blocks are integrated to generate a system-level schematic, and the variant overlays for a given set of design requirements are merged to generate a system variant overlay. Parameter values of the system variant overlay may then replace corresponding parameter values of the system-level schematic to generate a variant schematic for the given set of design requirements. Using this system and methodology, variant designs may be collaboratively generated by multiple designers each with expertise in particular schematic blocks and / or variant requirements, and may be shared either at the system level or at lower levels.

Feature points included in input images are extracted and matching information indicating mapping relationships for feature points included in different input images is generated. A reference image is selected among the input images based on the matching information. Valid images are determined among the input images by excluding noise images from the input images based on the matching information. A two-dimensional bundle adjustment is performed to generate synchronized images by aligning the valid images to the reference image. A merged image is generated by merging the reference image and the synchronized images. Image merging performance is enhanced by selecting the reference image highly correlated with the other input images and estimating exact homography based on the reference image.

The present invention relates to a method of efficiently managing dynamic multicast groups. In the method of efficiently managing dynamic multicast groups a hierarchical structure is used as a network structure for a multicast service. Accordingly, there are advantages in that groups can be merged or divided efficiently and overload depending on group management can be reduced.
