Creep rupture of materials: insights from a fiber bundle model with relaxation
, 2010 I adapted a model recently introduced in the context of seismic phenomena, to study creep rupture of materials. It consists of linear elastic fibers that interact in an equal load sharing scheme, complemented with a local viscoelastic relaxation ...

Predicted Device-Degradation Failure-Rate [PDF]
SAE Technical Paper Series, 2015 There is a concern that the continuing trend on miniaturization (Moore’s law) in IC design and fabrication might have a negative impact on the device reliability. To understand and to possibly quantify the physics underlying this concern and phenomenon, it is natural to proceed from the experimental bathtub curve (BTC) – reliability “passport” of the ...

Parameter Estimates of General Failure Rate Model: A Bayesian Approach [PDF]
, 2014 The failure rate function plays an important role in studying the lifetime distributions in reliability theory and life testing models. A study of the general failure rate model $r(t)=a+bt^{\theta-1}$, under squared error loss function taking $a$ and $b$

Patients' self-assessed functional status in heart failure by New York Heart Association class: a prognostic predictor of hospitalizations, quality of life and death. [PDF]
, 2010 BACKGROUND: Clinician-assigned New York Heart Association (NYHA) class is an established predictor of outcomes in heart failure. This study aims to test whether patients' self-assessment of functional status by NYHA class predicts hospital admissions ...

Failure Rate Estimation in a Dynamic Environment [PDF]
Economic Quality Control, 2015 Abstract We present a method to assess the reliability of a material operating in a dynamic environment. The dynamic environment is represented as a sequence of shocks governed by a self-exciting point process. The time-to-failure of the material is assumed to have a piecewise exponential distribution.

Detection Performance in Balanced Binary Relay Trees with Node and Link Failures
, 2012 We study the distributed detection problem in the context of a balanced binary relay tree, where the leaves of the tree correspond to $N$ identical and independent sensors generating binary messages.
