20090171921 | Accelerating Queries Based on Exact Knowledge of Specific Rows Satisfying Local Conditions - A method, computer program product, and system are provided for accelerating a query in a database system. For example, an embodiment of the method may include generating a data structure identifying a set of rows that satisfy conditions local to a table prior to an evaluation of a query and modifying the query based on the data structure. In addition, the method may include repeating the steps with respect to generating the data structure and modifying the query, if one or more additional local conditions are inferred from modifying the query based on the data structure. With respect to the step of modifying the query based on the data structure, in the case where no rows satisfy the local conditions in the data structure, an always false prefilter condition may be migrated as high as possible within the query. When only one row satisfies the local conditions in the data structure, a column may be replaced by a constant value from within that column in that one row. Further, in the case where a moderate number of rows satisfy the local conditions in the data structure and if sensible from a cost basis analysis, an IN condition may be inferred for each column from that table involved in a join condition. Application of these modifications prior to a determination of a query execution plan allows a query to be executed more efficiently and with far lower risk of applying a suboptimal execution plan. | 07-02-2009 |
20090171936 | System, Method, and Computer Program Product for Accelerating Like Conditions - A system, method, and computer program product are provided for optimizing LIKE-condition based queries on a table in a database system. | 07-02-2009 |
20110238677 | Dynamic Sort-Based Parallelism - A system, method, and computer program product are provided for sorting a set of records in a sort run. As the records are sorted, metadata regarding the sort run is gathered, and subsequently used to determine bounds of two or more disjoint subsets of the sort run. This enables the parallelization of several tasks over the sort run data using efficient, dynamic bounds determination, such as the outputting of sorted data from the disjoint subsets in parallel. | 09-29-2011 |
20120078880 | Accelerating Database Queries Containing Bitmap-Based Conditions - Systems, methods and articles of manufacture for accelerating database queries containing bitmap-based conditions are described herein. An embodiment includes determining a bitmap, where the bitmap represents a set of rows that have satisfied one or more conjunctive conditions which preceded a conjunct that is a disjunction in a query expression and restricting evaluation of a disjunct within the disjunction to the set of rows represented by the bitmap. Another embodiment includes determining a satisfaction bitmap, where the bitmap represents the result of one or more preceding disjuncts in a disjunction within a query expression and restricting scope of evaluation of a disjunct to a set of rows that are not within the determined satisfaction bitmap. In this way, embodiments of the present invention enable the acceleration of queries containing disjunctions of conditions on a database table, as well as reduce the temporary resources consumed for such queries. | 03-29-2012 |

20090001974 | Torque and load monitoring using magnetic sensor arrays - An apparatus for the nondestructive measurement of materials that includes at least two layers of electrical conductors. Within each layer, a meandering primary winding is used to create a magnetic field for interrogating a test material while sense elements or conducting loops within each meander provide a directional measurement of the test material condition. In successive layers extended portions of the meanders are rotated so that the sense elements provide material condition in different orientations without requiring movement of the test circuit or apparatus. In a bidirectional implementation the angle is 90° while in a quadridirectional implementation the relative angles are −45, 0, 45, and 90°. Multidirectional permeability measurements are used to assess the stress or torque on a component. These measurements are combined in a manner that removes temperature effects and hysteresis on the property measurements. This can be accomplished through a correction factor that accounts for the temperature dependence. After the corrections, the permeability measurement is then used to assess the local stresses and strains in the material of interest. | 01-01-2009 |
20090315540 | PRIMARY WINDINGS HAVING MULTIPLE PARALLEL EXTENDED PORTIONS - Reference standards or articles having prescribed levels of damage are fabricated by monitoring an electrical property of the article material, mechanically loading the article, and removing the load when a change in electrical properties indicates a prescribed level of damage. The electrical property is measured with an electromagnetic sensor, such as a flexible eddy current sensor, attached to a material surface, which may be between layers of the article material. The damage may be in the form of a fatigue crack or a change in the mechanical stress underneath the sensor. The shape of the article material may be adjusted to concentrate the stress so that the damage initiates under the sensor. Examples adjustments to the article shape include the use of dogbone geometries with thin center sections, reinforcement ribs on the edges of the article, and radius cut-outs in the vicinity of the thin section. | 12-24-2009 |
