Entropy characterisation of overstressed capacitors for lifetime prediction [PDF]

open access: yes, 2016
We propose a method to monitor the ageing and damage of capacitors based on their irreversible entropy generation rate. We overstressed several electrolytic capacitors in the range of 33 µF–100 µF and monitored their entropy generation rate View the ...

Adolescent conscientiousness predicts lower lifetime unemployment. [PDF]

open access: yesJournal of Applied Psychology, 2017
Existing research on Big Five personality and unemployment has relied on personality measures elicited after the respondents had already spent years in the labor market, an experience that could change personality. We clarify the direction of influence by using the British Cohort Study (N = 4,206) to examine whether conscientiousness and other Big Five

Supergravity at Colliders [PDF]

open access: yes, 2004
We consider supersymmetric theories where the gravitino is the lightest superparticle (LSP). Assuming that the long-lived next-to-lightest superparticle (NSP) is a charged slepton, we investigate two complementary ways to prove the existence of ...

Remark on formation of colored black holes via fine tuning [PDF]

open access: yes, 1999
In a recent paper (gr-qc/9903081) Choptuik, Hirschmann, and Marsa have discovered the scaling law for the lifetime of an intermediate attractor in the formation of n=1 colored black holes via fine tuning.

Global sensitivity analysis towards non-invasive parameterization of the electrochemical-thermal model for lithium-ion batteries

open access: yesAdvances in Applied Energy
High-fidelity electrochemical-thermal models are essential for performance improvement, charge/discharge strategy optimization, and the safe operation of lithium-ion batteries. However, model performance significantly relies on the accuracy of parameters,

Monte Carlo-Based Reliability Estimation Methods for Power Devices in Power Electronics Systems

open access: yesIEEE Open Journal of Power Electronics, 2021
Monte Carlo simulation has been widely used for reliability assessment of power electronic systems. In this approach, multiple simulations are carried out during the lifetime estimation of the components in power converter, e.g., power devices, where the

Lifetime Difference and Endpoint effect in the Inclusive Bottom Hadron Decays

open access: yes, 2004
The lifetime differences of bottom hadrons are known to be properly explained within the framework of heavy quark effective field theory(HQEFT) of QCD via the inverse expansion of the dressed heavy quark mass. In general, the spectrum around the endpoint
