The alternative to depending on training sites for classification is to apply the concept of signature extension. This term refers to the assumption that a single, more or less constant, spectral signature may be defined as characteristic of any class, and that this signature has broad(universal) applicability to any scene in a region, or even worldwide. As a specific example, the signature for winter wheat at its maturation should be essentially the same for fields in the U. S. Great Plains, Argentina, the Ukraine, and Australia-provided such variables as differing air masses, Sun position, soil types, soil moisture, etc. are compensated for. If that proves true, then an unknown feature or class in a given scene anywhere should be classifiable by comparing its spectral properties(for a Landsat pixel, its multiband digital number [DN] values) to a "data bank" containing standard values for each of many classes. The closest fit of the unknown's DN [digital number] values to those of some one class in the bank is assumed to identify it.  3, record 1, English, - signature%20extension

Transient liquid phase(TLP) bonding is a joining process in which a liquid-forming interlayer is placed between the substrates to be joined. At the bonding temperature, the interlayer initially liquates. Subsequently, interdiffusion between the liquid interlayer and the adjacent substrates results in a change in the overall composition of the joint, such that isothermal resolidification of the joint takes place. Standard models of the TLP process assume the sequential occurrence of discrete dissolution, isothermal solidification, and homogenization processes. This study uses edge-on transmission electron microscopy investigations to challenge the general applicability of such standard models to the TLP bonding of a variety of systems involving the B2 type intermetallic compound NiAl as a substrate material.  2, record 2, English, - transient%20liquid%20phase%20bonding
