The invention discloses a distributed query method of spatial service data. The distributed query method of the spatial service data comprises querying and parsing a spatial querying and processing object to generate a parsed and optimized spatial query plan; submitting a spatial data query to a service data access and integrated-service end which supports spatial function development; performing interactive operation on query workflow and back-end data service resources which support spatial development and spatial-data storage and returning a query result to an access and integrated client which calls service to apply. The distributed query method of the spatial service data has the advantages of being capable of performing distributed query on the spatial service data based on service access and an access method of the spatial service data, performing integrated-query on geographically distributed data source through a data service request, combining a returned result data-set and guaranteeing the data-consistency of an access and integrated process in a data protocol.

A memory is encoded with a model of sensitivity of a distorted layout generated by simulation of a wafer fabrication process, with respect to a change in an original layout that is input to the simulation. The sensitivity model comprises an expression of convolution of the original layout with spatial functions (“kernels”) that are identical to kernels of a process model used in the simulation. A difference between the distorted layout and the original layout is computed, and the difference is divided by a sensitivity value which is obtained directly by evaluating the kemel-based sensitivity model, and the result is used to identify a proximity correction (such as serif size or contour movement) to be made to the original layout. Use of a sensitivity model based on a process model's kernels eliminates a second application of the process model to evaluate sensitivity, thereby to reduce memory and computation requirements.

A dimensionality reduction method and system for efficient color transform compression is disclosed. A multi-dimensional color transform with an n-dimensional input color space can be received. A projection operator can be derived and applied to the n-dimensional input color space to form a k-dimensional input color space. A functional approximation can be designed to the n-dimensional input color space and can be evaluated on the k-dimensional input color space to form an m-dimensional output color space. The projection operator and the approximation function can be combined to form a compressed transform by mapping the n-dimensional input color space to m-dimensional output color space. Such an approach provides a significant reduction in size of the color profile with respect to storage and speeds-up real-time computation.

The Radio Resource Management (RRM) operates in a cellular network either of the the 2 or 3 generation in order to bias TDMA traffic towards prefixed directions of sectored cells. The network is built up by replicating a network base element over a wide synchronised area. The base element includes one or more sectored cells either disjoint or superimposed to each other. The base stations exploit directive antennas able to cut out the gain for sectoring the cells and measuring the directions of arrival (DOA) of the users signals. The RRM plans the transmissions of the mobiles and the serving BTSs by allocating the available timeslots to sectors which don't overlap, as far as possible, the sectors of adjacent or superimposed cells during a same active timeslot. The last is also allocated to the users whose DOAs best match with the angular positions of the relevant sectors. A suitable configuration table is generated by mapping a subset of the possible allocations between cell/s, sectors, and timeslots. Starting from the selection of an initial configuration in the table, suitable spatial functions are generated to define the configurations of all the adjacent elements, in order to achieve maximum interference rejection.
