In this paper, an adaptive inverse Gaussian stochastic process is developed to characterize the degradation process of condition monitored components. The knowledge of the degradation process is updated through the parameter of the process when new observations are available. The updating is performed through a general Bayesian filtering process within a state space model setting. The proposed ...

The Karhunen-Loève transform (KLT) is an optimal method for dimensionality reduction, widely applied in image compression, reconstruction and retrieval, pattern recognition and classification. The basic idea consists in evaluating, starting from a set of representative examples, a reduced space, which takes into account the structure of the data distribution as much as possible, and representin...

Australia has been cited as a weak link in anthropogenic models of megafauna extinction, but recent work suggests instead that the evidence for rapid extinction shortly after human arrival is robust. The global model is revisited, based on the contention that late Pleistocene megafauna extinctions took place rapidly on islands, and some islands (such as Australia and the Americas) are much larg...

We generalise Grabisch and Rusinowska (2013) to non-conformist societies. Agents in a network are iteratively picking yes/no opinion, where updating stems from mutual influence. introduce notion of groups based on the signs examine few canonical societies, namely, conformist, communitarian, with leaders, anti-conformist agents. investigate stability issues. Any kind opinion model can be hosted ...

In this paper, a formal model for antivirus update agent system is presented based on mobile agent technology and predicate/transition Petri nets. The mobile agent system contains two mobile agents called DCA and UNA. It sends out agents to update antivirus on client computers in a network. Each agent takes on a specified responsibility. First, DCA roams through the network and check the last d...
