Fuzzy Fault Tree Analysis of Crane Wire Rope
Wire rope is a very useful and long lasting structural element when properly used and maintained. For a failure such as that of crane wire rope, it is often very difficult to estimate precise failure rates or failure probabilities of individual components or failure events. Conventional fault tree analysis (FTA) is based on the probability assumption. When the failure probability of a system is...
متن کاملProbability Density Estimation Using Entropy Maximization
We propose a method for estimating probability density functions and conditional density functions by training on data produced by such distributions. The algorithm employs new stochastic variables that amount to coding of the input, using a principle of entropy maximization. It is shown to be closely related to the maximum likelihood approach. The encoding step of the algorithm provides an est...
متن کاملProbability Density Function Estimation using theMinMax
| The problem of initial probability assignment consistent with the available information about a probabilis-tic system is called a direct problem. Jaynes' maximum en-tropy principle (MaxEnt) provides a method for solving direct problems when the available information is in the form of moment constraints. On the other hand, given a probability distribution, the problem of nding a set of constra...
متن کاملProbability density estimation using artificial neural networks
We present an approach for the estimation of probability density functions (pdf) given a set of observations. It is based on the use of feedforward multilayer neural networks with sigmoid hidden units. The particular characteristic of the method is that the output of the network is not a pdf, therefore, the computation of the network’s integral is required. When this integral cannot be performe...
متن کاملWire Rope Sheave Friction Effects
When a takeup weight is offset to the side of a conveyor, a wire rope is commonly routed from the take-up weight through a series of sheaves to the take-up carriage. The friction developed from a series of wire rope sheaves can effect the actual belt tension at the take-up carriage. Through real-time testing the actual tension on a takeup carriage was recorded with data acquisition using an int...
