摘要： For most large 3D engineering models, the instance positions of repeating instances of connected components show significant multiple spatial aggregation. The invention uses several KD-trees, each for one cluster of points which are spatially aggregated. The multiple KD-trees generate a relatively short data stream, and thus improve the total compression ratio. A method for encoding points of a 3D mesh model comprises steps of determining that the mesh model comprises repeating instances of a connected component, and determining for each repeating instance at least one reference point, clustering the reference points of the repeating instances into one or more clusters, and encoding the clustered reference points using KD-tree coding, wherein for each cluster a separate KD-tree is generated.

摘要： Common 2D or 3D mesh models comprise redundancy in the form of symmetries, such as repetitive structures. For complexity reduction, the redundant structures must be detected. An improved method for sampling mesh models comprises sampling the model (710) using an initial sampling step size, detecting (720) a representative of a repeating structure, instances of the repeating structure and a remainder of the model, and sampling (780) the remainder and the representative using a first reduced sampling level according to a first reduced sampling step to size. The method comprises detecting (730) a size of said representative of a repeating structure, a size of the instances of the repeating structure and a size of said remainder, and calculating (740) the first reduced sampling step size based on the size of the instance and the total size of the model. The method can be repeated recursively.

摘要： A system and method for minimizing interference for mobile devices in a communication network that includes a macrocell base station and a femtocell having a base station. The method receives initialization data on a backhaul connection between the femtocell base station and the macrocell base station, and uses that data to configure the femtocell base station transmitting power. The method receives a user equipment identifier from a macrocell user equipment in the communication network, and determines whether the macrocell user equipment is authorized. If authorized, the macrocell user equipment is granted access to the femtocell base station. If unauthorized, user equipment information for the macrocell user equipment received on the backhaul connection is used to adjust the femtocell base station transmitting power to minimize the interference for mobile devices.

摘要： A system and method for minimizing interference for mobile devices operating in a communication network that includes a centralized controller and a number of femtocells, each femtocell including a base station. The method calculates a power assignment priority for each femtocell, and determines a priority order of the femtocells, the priority order based on the power assignment priority calculated for each femtocell. The method calculates a power to assign to the base station for each femtocell based on the priority order. The method allocates a first portion of the power assigned to the base station for each femtocell as required for real-time traffic, and a second portion of the power assigned to the base station for each femtocell as required for non-real-time traffic.
