Innovations for adaptive compression and decompression for dictionaries of a column-store database can reduce the amount of memory used for columns of the database, allowing a system to keep column data in memory for more columns, while delays for access operations remain acceptable. For example, dictionary compression variants use different compression techniques and implementation options. Some dictionary compression variants provide more aggressive compression (reduced memory consumption) but result in slower run-time performance. Other dictionary compression variants provide less aggressive compression (higher memory consumption) but support faster run-time performance. As another example, a compression manager can automatically select a dictionary compression variant for a given column in a column-store database. For different dictionary compression variants, the compression manager predicts run-time performance and compressed dictionary size, given the values of the column, and selects one of the dictionary compression variants.

A guitar has a wrench tremolo bar thereon, replacing the standard tremolo bar, with the wrench tremolo bar having a desired wrench on at least one end of the wrench tremolo bar, to cooperate with the string fasteners on the guitar, which greatly facilitates tuning, changing or replacing of a guitar string.

In a method for analyzing the driving accuracy of a golfer, the number of fairway hits and the severity level of the number of fairway misses is adjusted based on a course rating and slope rating of the current and average courses in a database. An adjusted total stroke cost is applied to a driving accuracy handicap lookup table to produce a driving accuracy handicap. This handicap is graphically displayed to the user by itself, or compared to the driving accuracy handicap of users of the same or similar skill level. Finally, a hole-by-hole analysis can be graphically displayed to give a graphic representation of where the golfer needs improvement.
摘要:
In a method for analyzing performance of a golfer, a number greens hit in regulation by the golfer during at least one round of golf and a number of long game strokes taken by the golfer during the at least one round of golf are determined, a long game efficiency index of the golfer is calculated by dividing the determined number of long game strokes by the determined number of greens hit in regulation, and a long game handicap of the golfer is determined based at least in part upon the calculated long game efficiency index and a known relationship between long game handicap versus long game efficiency index. The method may be performed by a computer system if desired.
摘要:
A pattern can be identified in at least part of a query whose definition is received in a query request. The identified pattern can be matched with a set of pre-defined patterns, each of which has associated therewith at least one pre-compiled query execution sub-component of a plurality of pre-compiled query execution sub-components retained in a library. A plan for executing the query can be generated, for example by incorporating the pre-compiled query execution sub-component associated with the matched pattern into the plan based on a pseudo code representation of the plan derived from the definition.

A method of determining a time-dependent route parameter for a transportation network, for use in an automated routing system in connection with traffic, transportation, and logistics is provided. While shortest distances from all source nodes in S to all target nodes in T are time-independent, travel times are not. The method models the transportation network and computes travel costs from an arbitrary starting node to a plurality of intermediate way-points, and from intermediate way points to the target node.

The present invention relates to slowly digestible storage carbohydrates (starch, glycogen) having a branching degree of at least 8.5% and a side chain composition comprising at least 10% of DP 5-7. Said slowly digestible carbohydrates can be produced by treating the substrate (glycogen, starch) from a native source with a glycogen branching enzyme derived from Rhodothermus obamensis, Rhodothermus marinus, Deinococcus radiodurans or Deinococcus geothermalis.
