The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank...
Evaluation conferences such as TREC, CLEF, and NTCIR are modern examples of the Cranfield evaluation paradigm. In the Cranfield paradigm, researchers perform...
Many applied problems resulting in hyperbolic conservation laws are nonstrictly hyperbolic. As of yet, there is no comprehensive theory to describe the...
It is known that metallic nanostructured materials possess mechanical properties far in excess of those predicted by standard models such as the Hall-Petch...
The surface crack in flexure method features a small, well-defined crack commensurate in size with natural flaws in structural ceramics. Lateral cracks may...

Changes in phase separation morphology occurring in thin polymer blend films is discussed. These changes are especially large when the films are thinner than...
Using a modified Marciniak biaxial stretching test, we are able to produce large samples with uniform amounts of balanced biaxial strain. The sheets were fully...

A calcium phosphate cement (CPC) sets to hydroxyapatite and has been used in dental and craniofacial applications. However, when CPC was used in periodontal...
The superelastic deformation of shape memory alloys has intrinsic instability as a result of incompatibility between martensite and austenite phases at stress...
A microsecond-resolution technique was used to measure the heat of fusion, specific heat capacity and electrical resistivity of niobium and titanium in the...
Over the last thirteen years the Versailles Advanced Materials and Standards (VAMAS) project has conducted five full fledged, international round robins on...
Cluster expansion Hamiltonians derived from pseudopotential total energies were used to predict ground-state (GS) cation configurations for some A(B^{3+}1⁄2B'^...
Calcium phosphate cement (CPC) sets to form hydroxyapatite and has been used in medical and dental procedures. However, the brittleness and low strength of CPC...

High nitrogen stainless steels (HNSS) are a class of materials that demonstrate an attractive combination of strength, ductility, and corrosion resistance...
Relatively little attention has been devoted to the direct electrodeposition of transition metal-aluminum alloys in spite of the fact that isothermal...
Research at NIST on the production of metal powder by gas atomization has focused on the development of sensors for use in PC based control systems. The...
