Some Properties of Statistical Reliability Functions

open access: yesThe Annals of Mathematical Statistics, 1966
Networks with independent components are considered. Assuming all components to have a probability $p$ of functioning we study the properties of the reliability function $R(p)$ that the network functions. In particular, we investigate networks of high order.

Improving the reliability of functional localizers

open access: yesNeuroImage, 2011
A critical assumption underlying the practice of functional localization is that the voxels identified by functional localization are essentially the same as those activated in the main experiment for a particular anatomical area. Violations of this assumption bias the resulting analyses and can dramatically increase the likelihood of both Type I and ...

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Bayesian Estimation of Reliability of the Electronic Components Using Censored Data from Weibull Distribution: Different Prior Distributions

open access: yesInternational Journal of Industrial Engineering and Production Research, 2014
The Weibull distribution has been widely used in survival and engineering reliability analysis. In life testing experiments is fairly common practice to terminate the experiment before all the items have failed, that means the data are censored.

Estimation of the two-parameter Weibull distribution parameters using the coefficient of variation

open access: yesVojnotehnički Glasnik, 1996
This paper presents a method for estimating the reliability function parameters when reliability function is the 2-parametar Weibull regression. This model is often used in a reliability analysis in wide variety of situations to approximate successfully ...

Multivariate reliability modelling with empirical Bayes inference [PDF]

open access: yes, 2007
Recent developments in technology permit detailed descriptions of system performance to be collected and stored. Consequently, more data are available about the occurrence, or non-occurrence, of events across a range of classes through time.

Algorithms and formulas for conversion between system signatures and reliability functions [PDF]

open access: yes, 2015
The concept of signature is a useful tool in the analysis of semicoherent systems with continuous and i.i.d. component lifetimes, especially for the comparison of different system designs and the computation of the system reliability.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

An optimal scale for the comparison of air pollution in east and west Tehran [PDF]

open access: yesعلوم محیطی, 2018
Introduction: Air pollution in the metropolis of Tehran is a serious environmental issue. Assigning an optimal budget to deal with air pollution problems in the East (no.4) and West (no.22) regions of Tehran, determining the optimal proportion of green ...
