Image segmentation is the process to capture the object from the background and it is a difficult task when a vision of the object is in stochastic region. Here introduce in this paper extension of stochastic random walker segmentation method. In stochastic random walker segmentation, a weighted graph is built from the image, where the each pixel considered as a node and edge weights depend on ...

We consider a model of pollution accumulation in which a catastrophic environmental event occurs once the pollution stock exceeds some uncertain critical level. This catastrophic event is irreversible in the sense that once it has occurred economic activities become impossible. Usually, in this type of model, the variable of interest, i.e. the critical pollution threshold, is modelled as a real...

Value at risk is a device to measure the maximum possible loss when right tail distribution ignored. Since uncertain random variables provide tool deal with phenomena in which uncertainty and randomness simultaneously exist, this paper proposes computational approach for value of variables. In fact, chance can be expressed based on expectation respect probability functions. Thus, distributions ...
