A device transferring method and a device arraying method are provided for readily transferring a number of devices from a first substrate to a second substrate such that the devices are enlargedly spaced from each other with a pitch larger than an array pitch of the devices arrayed on the first substrate. A tablet may be placed within the vessel such that it is in thermal communication with the heat source to receive heat therefrom. In various embodiments, the adjusted read threshold is determined in a variety of described ways that are based on a number of described factors. Several dissimilar digital signature algorithms may be used to reduce vulnerability from algorithm compromise, and subsets of multiple digital signatures may be used to reduce the scope of any specific compromise. 5 turbine bucket chord lengths as measured at the hub from the trailing edge, and the central surface and the downstream section of the casing being at least substantially parallel or divergent from the trailing edge. Other embodiments are described and claimed.
