Stochastic Programming with Probability [PDF]

open access: yes, 2007
In this work we study optimization problems subject to a failure constraint. This constraint is expressed in terms of a condition that causes failure, representing a physical or technical breakdown.

Joint optimization method of failure probability and fiber-link load balancing in flexible bandwidth optical network

open access: yesTongxin xuebao, 2019
In order to gain insight into the relationship between the failure probability and the spectrum efficiency,both failure probability (FP) and load balancing (LB) were attempted to minimize in flexible bandwidth optical networks.An optimized FP-LB ...

Effects of Electrode Composition and Thickness on the Mechanical Performance of a Solid Oxide Fuel Cell

open access: yesEnergies, 2018
Mechanical damage is a major factor limiting the long-term stability of solid oxide fuel cells (SOFCs). Here, the mechanical stability of planar SOFCs consisting of Ni-YSZ anode/YSZ electrolyte/LSM-YSZ cathode (Ni=Nickel, YSZ=yttria-stabilized zirconia ...

Probabilistic metrology or how some measurement outcomes render ultra-precise estimates [PDF]

open access: yes, 2016
We show on theoretical grounds that, even in the presence of noise, probabilistic measurement strategies (which have a certain probability of failure or abstention) can provide, upon a heralded successful outcome, estimates with a precision that exceeds ...

Study of skills of examination engineer in ultrasonic examination of piping welds and acceptance criteria for grading based on damage probability

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Generally in Japan, high skilled UT engineer performed examination and high reliability of examination results are achieved. However, it is not confirmed how high skill and actual probability of detection (POD).

Prediction of corrosion failure probability of buried oil and gas pipeline based on an RBF neural network

open access: yesFrontiers in Earth Science, 2023
Risk assessment is critical to ensure the safe operation of oil and gas pipeline systems. The core content of such risk assessment is to determine the failure probability of the pipelines quantitatively and accurately.

Simplified modelling of the performance of concrete tunnels during fire and post-fire damage classification

open access: yesActa Polytechnica CTU Proceedings, 2022
The performance of concrete tunnel structures during and after fire is not well understood. This is an obstacle to the adoption of risk-based approaches for fire safety design of tunnel structures.

Multiple Organ Failure Complicating Probable Scrub Typhus [PDF]

open access: yesClinical Infectious Diseases, 2000
This report describes a case of life-threatening acute respiratory distress syndrome with multiple organ failure complicating probable scrub typhus. Favorable outcome was associated with fluoroquinolone therapy. Scrub typhus should be suspected in travelers returning from Southeast Asia presenting with unexplained respiratory manifestations.
