Stochastic analysis of the influence of tower shadow on fatigue life of wind turbine blade
Wind turbine blades Stochastic fatigue damage Tower shadow Tower design Monte Carlo simulation
2012/4/26
Fatigue damage accumulation in upwind turbine blades is primarily influenced by turbulence in the inflow. However, the stress reversals during blade passages through the stagnating and deflected mean ...
Joint distribution model for prediction of hurricane wind speed and size
Hazard Risk Hurricane Wind speed Storm size Simulation Performance-based engineering
2012/4/26
This paper suggests a methodology for characterizing the joint distribution of hurricane intensity (maximum wind speed) and size (radius of maximum winds). Such a model represents an extension of trad...
Establishment of generic transformations for geotechnical design parameters
Transformation uncertainty Geotechnical design parameter Reliability-based design Correlation CPTU tests Undrained shear strength
2012/4/26
Geotechnical design parameters are typically estimated based on the transformations from site investigation results. In general, one expects the transformation uncertainty to change depending on the n...
Estimating Human Error Probability using a modified CREAM
Human Error Probability Human reliability CREAM Common performance condition
2012/4/22
Human Error Probability (HEP) point estimation is important for Probabilistic Safety Assessment (PSA) of socio-technical systems. We present a modified basic method of CREAM to provide the point estim...
Data survivability vs. security in information systems
Data survivability Data security Protection Redundancy Attack Optimization
2012/4/16
A multiple objective problem formulation and solution methodology is presented to select optimal information and data storage configurations considering both data survivability and data security, as w...
A novel tool for organisational learning and its impact on safety culture in a hospital dispensary
Safety culture Organisational learning Safety management Patient safety Healthcare
2012/4/16
Incident reporting as a key mechanism for organisational learning and the establishment of a stronger safety culture are pillars of the current patient safety movement. Studies have suggested that inc...
Modified Weibull model: A Bayes study using MCMC approach based on progressive censoring data
Modified Weibull distribution Progressive type-II censoring Balanced loss Maximum likelihood estimation Bayesian estimation Gibbs and Metropolis–Hasting samplers Hybrid MCMC approach Bootstrap
2012/4/22
In this paper, we investigate the problem of point and interval estimations for the modified Weibull distribution (MWD) using progressively type-II censored sample. The maximum likelihood (ML), Bayes,...
An analytical formulation for the fatigue damage skewness relating to a narrowband process
Fatigue damage Uncertainty Skewness Narrowband process Linear oscillator
2012/4/26
In spectral fatigue analysis, the expected fatigue damage is customarily used to ascertain the design fatigue life. The uncertainty of the damage induced by the underlying stochastic process is typica...
Out-of-plane seismic performance and fragility analysis of anchored brick veneer
Brick masonry veneer Metal tie connections Fragility analysis Nonlinear dynamic analysis
2012/4/26
The out-of-plane seismic fragility of single-story brick veneer walls built over a wood frame backup was evaluated analytically. Two-dimensional (2-D) finite element (FE) brick veneer wall strip model...
Ergodicity of forward times of the renewal process in a block-based inspection model using the delay time concept
Forward time Delay time Inspection Limiting distribution Ergodic Markov chain
2012/4/16
The delay time concept and the techniques developed for modelling and optimising plant inspection practice have been reported in many papers and case studies. For a system subject to a few major failu...
Measuring direct and indirect treatment effects using safety performance intervention functions
Intervention models Full Bayes estimation Poisson–lognormal regression Random parameters models Treatment effectiveness index
2012/4/14
Recent traffic safety research has advocated the use of the Full Bayes (FB) approach to conduct controlled before–after safety evaluations. The FB approach was shown to offer both methodological and d...
On the critique of Beck’s view on risk and risk analysis
Risk Probability Ulrich Beck Critique Foundational issues
2012/4/12
Ulrich Beck’s stand on risk and risk analysis has been challenged by many researchers. In this paper we look closer into some of the arguments used, with a main focus on the fundamental analysis carri...
