Embodiments of the present invention relate to invoking and managing a failover of a storage account between partitions within a distributed computing environment, where each partition represents a key range of data for the storage account. Deformation is provided by an electrostatic force between two of the layers. The user is enabled to sense one or more of the error conditions prior to the periodic sampling of the condition in the error log to thereby bypass the error log sampling to provide for a possible real-time response to a sensed error condition. With the length of the control rod guide thimble represented by L, the effective length of the small diameter section is selected to lie within a range of from 0. The handle is attached to a proximal end of the measurement member. A level-1 soft judgment target signal is produced by using soft judgment target signals that are outputted by two sets of level-0 cells respectively and, similarly, a level cell is formed by using two sets of level-N cells, whereby a soft judgment target signal creation portion with a hierarchical structure is constituted.
