  • Patent number: 9965516
    Abstract: A method and apparatus for outer-joined and/or cross-joined table elimination for duplicate-insignificant queries is provided. A query block of a query specifies a join between a first table and a second table. The join is one of an outer join and a cross join. A first determination is made that the query block contains no references to the second table to be processed after the join. A second determination is made that the query block is duplicate-insignificant. In response to making the first determination and the second determination, the query block is transformed into a transformed query, where the second table is eliminated from a corresponding query block in the transformed query.

  • Publication number: 20170351316
    Abstract: In some aspects, a method for adjusting an operating frequency of a memory controller is provided, wherein a graphics processing unit (GPU) accesses a memory via the memory controller. The method includes monitoring activity of the GPU to determine an active time of the GPU, comparing the determined active time with an active threshold, and, if the determined active time is greater than the active threshold, increasing the operating frequency of the memory controller.

  • Patent number: 9234189
    Abstract: The present invention provides a hybrid-type histidine kinase gene isolated from indica rice IR64, and being capable of osmosensing and inducible by multiple stresses, and hence, being capable of improving the multiple stress tolerance of the crop plants even in subsequent generations so as to make the plants capable of coping-up with the more than one environmental abiotic stress conditions, and therefore, increasing the economic value of the crop plants while maintaining the yield thereof. The present invention also provides a method of isolation of hybrid-type histidine kinase gene from indica rice IR64, and its functional characteristics and its sequence listing and cloning, at least, with yeast expression vector and the plant expression vector, and clones produced thereby, and method of improving multiple stress tolerance of crop plant and crop plants having improved multiple stress tolerance.

  • Patent number: 8490038
    Abstract: A system, method, and computer program product for automatically placing contact cuts in integrated circuit layouts, particularly in guard rings, inter-layer via connections, and various space-filling structures typically defined by polygons or paths. Areas to be filled with contact cuts are partitioned horizontally and vertically, and decomposed into shared and exclusive type regions that are sorted directionally. Contact cuts are placed in each region according to its type and according to relevant design rules on contact cut spacing and enclosure constraints. Contact cuts that may cause design rule violations are deleted. Narrow jogs or cuts, merged shared regions, and non-orthogonal edges or segments in the decomposed regions are handled by alternate embodiments. The result is automated contact cut placement, even for merged/chopped layout features, that is generally more symmetric, collinear, and adds an optimal number of contact cuts in most cases than with existing tools.
