摘要： A data storage system stores a set of codewords in memory. The set of codewords are encoded in accordance with a joint nesting matrix specifying multiple layers of integrated interleaved codes, including first, second and third layers of integrated interleaved codes, and the set of codewords stored in the memory include first, second and third layers of parity information corresponding to the first, second and third layers of integrated interleaved codes. When decoding a first codeword and a first subgroup containing the first codeword fail, the system decodes a group of codewords that include two more subgroups of codewords, including the first subgroup of codewords, using the third layer parity information for the group of codewords. The second and third layers of integrated interleaved codes are configured to enable decoding of two codewords, in a subgroup of codewords, having errors beyond the correction capability of the first layer codes.

摘要： A method constructs an image with improved peak signal-to-noise ratio (PSNR) from a scattered pixel set. The method generates an approximation function that is a linear combination of a plurality of Many-Knot (MK) spline basis functions, and constructs the image with improved PSNR by conducting a least squares treatment on the approximation function to minimize a residual of each pixel value in the scattered pixel set from the approximation function.

摘要： In one embodiment, a method for improving cardinality estimation of a join predicate between a fact table and an overloaded dimension table is provided. The method includes receiving a dimension table and a fact table in a join predicate of one or more SQL statements. The method further includes identifying a majority of records in the fact table that refer to a subset of records in the dimension table. The method further includes computing a filter factor of the join predicate between the dimension table and the fact table. The method further includes creating a statistical view using one or more relevant portions of the dimension table that are referred to by the fact table.

摘要： A database cluster is provided. The database cluster includes a plurality of nodes. When a change is implemented at a first given node of the database cluster, the change is communicated to other nodes of the database cluster to synchronize data between the nodes. For this purpose, the first given node generates information by applying a hash function to a database key indicative of where the change is to be implemented. Subsequently, the first given node includes the information generated by the hash function into the change, and communicates the change along with the information to a second given node of the database cluster.

摘要： Methods and apparatus are disclosed for symbolic methods using algebraic geometry (e.g., based on a Gröbner basis of tangent space polynomials of parametric curves). For example, the design, optimization and verification of silicon photonic wave guides using parametric polynomials and/or Gröbner basis functions can be used to perform envelope generation, rectification, manufacturability checking, singularity detection, reticle and etch processing model generation, tapering loss minimization, and bend loss minimization. In one example, a method of analyzing a layout to be manufactured using a photolithographic process includes producing an envelope of a curve representing a layout object based at least in part on a Gröbner basis and performing one or more analysis operations for the envelope to perform verification and manufacturability checks.
