Influences of variables on ship collision probability in a Bayesian belief network model
Maritime accidents Bayesian networks Sensitivity analysis Mutual information Causation probability
2012/4/15
The influences of the variables in a Bayesian belief network model for estimating the role of human factors on ship collision probability in the Gulf of Finland are studied for discovering the variabl...
Towards automatic and robust adjustment of human behavioral parameters in a pedestrian stream model to measured data
Cellular automaton Pedestrian simulation Fundamental diagram Calibration Parameter sensitivity
2012/3/26
People die or get injured at mass events when the crowd gets out of control. Urbanization and the increasing popularity of mass events, from soccer games to religious celebrations, enforce this trend....
Hybrid reliability model for nuclear reactor safety system
Hybrid reliability model Markov process Reliability block diagram Shutdown system Belgian reactor 2
2012/4/16
The dependability of critical safety systems needs to be quantitatively determined in order to verify their effectiveness, e.g. with regard to regulatory requirements. Since modular redundant safety s...
Subset Simulation of a reliability model for radioactive waste repository performance assessment
Radioactive waste repository Performance assessment Reliability model Subset Simulation Markov Chain Monte Carlo
2012/4/22
In this paper, we show an original application of the Subset Simulation (SS) technique on a model for the performance assessment of a near surface radioactive waste repository. The logic of the protec...
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...
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,...
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...

2012/4/22
ontribution to sample variance plot? a natural extension of the ontribution to the sample mean plot? which is a graphical tool for global sensitivity analysis originally proposed by Sinclair. These gr...
Long-term prediction model of rockburst in underground openings using heuristic algorithms and support vector machines
Underground openings Rockburst Prediction Classification Genetic algorithm (GA) Particle swarm optimization algorithm (PSO) Support vector machines (SVMs)
2012/3/27
Rockburst possibility prediction is an important activity in many underground openings design and construction as well as mining production. Due to the complex features of rockburst hazard assessment ...
Investigation into the nonlinear damage model of coal containing gas
Nonlinear Damage model Coal containing gas Outburst of coal and gas
2012/4/12
By taking the nonlinear deformation properties of coal into consideration, the nonlinear constitutive equation was founded. And in view of the compressible property of gas, the idea of compressive ene...
