X-ray induced fluorescence measurements, using high energy synchrotron radiation generated on the Sector 1 Insertion Device beamline at the Advanced Photon
Two MgO-doped Si3N4 specimens (Norton, NC-132) were tested in ultra-long flexure stress rupture experiments with an external load of 266 MPa, i.e., 14.941 and
We document methods for the quantitative evaluation of systems that produce a scalar summary of a biometric sample¿s quality. We predicate this on the idea that
We present magnetization and magnetoresistance data at liquid-helium and liquid-nitrogen temperatures for wire materials commonly used for instrumentation
For weighted means estimators of the common mean of several normal populations associated (conservative) confidence intervals are constructed. These intervals
The elastic constants and internal friction of induction hardened and unhardened SAE 1050 plain-carbon steel were determined by acoustic resonance spectroscopy
