One example being, an improved downhole tool and method for transmitting data signals from a downhole environment to surface, the downhole tool comprising a fluid actuated flow restrictor; a first fluid flow path for flow of actuating fluid to actuate the flow restrictor; a second ...

A yield management method and system for maximising revenue obtained from a given capacity that is offered by a cargo flight. The capacity is defined by the weight and the volume of the freights that may be transported by the cargo flight. A set of historical profiles of the capacity reserved by each category is stored for different previous instances of the cargo flight. Corresponding potential p...

Provided is a computation apparatus that is able to adequately obtain a relative value of an incentive point issued by each shop, by computing an exchange rate used in exchanging shop points of the shop into common points. The computation apparatus ( 25 ) stores a function for defining the exchange rate ( 250 ), and internally maintains, for rate computation, the used house point (UHP) that repres...

In a processor, an ALU or a decode portion comprises a sign reversal portion 101 for reversing the sign of a first input value, a sign determination portion 102 for determining the sign of a second input value, and an output selection portion 103 for selectively outputting the first input value, if the determination result of the sign determination portion 102 is positive, selectively outputting t...

The decision to prefetch inodes is based upon the detecting of access patterns that would benefit from such a prefetch. Once the decision to prefetch is made, a plurality of inodes are prefetched in parallel. Further, the prefetching of inodes is paced, such that the prefetching substantially matches the speed at which an application requests inodes.
