Traditional approaches like MIL-HDBK, Telcordia, and PRISM etc. have limitation in accurately predicting the reliability due to advancement in technology, process, materials etc. As predicting the reliability is the major concern in the field of electronics, physics of failure approach gained considerable importance as it involves investigating the root-cause which further helps in reliability ...

The combined topics of reliability and security are briefly traced in relation to the past and present endeavors of the Air Force Research Laboratory’s Information Directorate. 1. The Past and the Future Prior to being integrated into the Air Force Research Laboratory, the former Rome Laboratory had for many decades a distinguished reliability research program. Because many of the electronic sy...

Bending fatigue tests with stress ratio R = -1 and 0 of as welded (AW) relieved (SR) root-failed plug weld (PW) specimens toe-failed out-of-plane gusset (GW) T-joint (TJ) are performed. The welding residual (WRS) at the root notch toe AW SR measured by XRD method. mean effect test results analyzed using modified MIL-HDBK-5D equivalent σeq based on hot spot (HSS) 'root local (RLS)' determined tw...

The application of parametric reliability analysis methods for repairable units, such as Power law process, is quite clear and straightforward for a single repairable unit. However, in practice, the analyst needs to know the reliability characteristics of units at a fleet level. The application of parametric reliability analysis methods at the fleet level, even if it is limited in scope, is qui...

The reliability of power electronic devices and components is very important to manufacturers. In recent years, many researchers have conducted reliability assessments of power electronic devices, yet the reliability of numerous circuits used widely has not been evaluated. This paper presents a comprehensive reliability evaluation of fundamental multilevel inverters. The reliability of the mult...

Achieving a high level of reliability is of utmost importance in military applications. A given military grade part is extremely more expensive than its commercial counterpart. This great price difference is mainly due to the differences in design, manufacturing and the quality of parts used in commercial versus military products. Moreover, design of military grade products is much more difficu...

DATA QUALITY AND PEDIGREE Introduction Data are scientific or technical measurements represented by numbers or other means [1]. Their importance in scientific and engineering work can never be stressed enough. The heart and soul of statistical analysis are the data. It is well known that bad data induces the so-called GIGO model: Garbage In, Garbage Out. In plain English, no statistical procedu...

The robust gallium carboxylate Ga(OH)(btec)·0.5H2O (MIL-61) is selected as a parent MOF to prepare Ln-MIL-61 by PSM. This work investigates the luminescence of Ln-doped MIL-61 (Ln = Eu3+, Tb3+, Sm3+, Dy3+) in the visible light region. Upon 314 nm excitation, the emission spectra of Eu-MIL-61, Tb-MIL-61 and Eu/Tb-MIL-61 all exhibit their respective strong sharp emission bands. However, Sm-MIL-61...
