The adoption of cooperative intelligent transportation systems (cITSs) improves road safety and traffic efficiency. Vehicles connected to cITS form vehicular ad hoc networks (VANET) exchange messages. Like other systems, cITSs are targeted by attackers intent on compromising disrupting system integrity availability. They can repeatedly spoof false information causing bottlenecks, jams even acci...

Application of Bayesian belief networks in systems that interact directly with human users, such as decision support systems, requires eeective user interfaces. The principal task of such interfaces is bridging the gap between probabilistic models and human intuitive approaches to modeling uncertainty. We describe several methods for automatic generation of qualitative verbal explanations in sy...

Belief systems, which are one of the four levers control, play a vital role in an organization. This study is primarily aimed at examining effects belief systems on managerial performance. Since control jointly function management we extend our by investigating whether contingent-fit between strategic risk, uncertainty, and other three (i.e., boundary diagnostic interactive control) strengthens...

In this paper, we focus on diagnosis in distributed computer systems using end-to-end transactions, or probes. Diagnostic problem is formulated as a probabilistic inference in a bipartite noisy-OR Bayesian network. Due to general intractability of exact inference in such networks, we apply belief propagation (BP), a popular approximation technique proven successful in various applications, from...

We give a model for a multi-agent system which describes how the knowledge and beliefs of agents should change when they receive new information. The formal tool we use for this description is a combination of modal and dynamic logic. Two core notions in our model of belief update are the expansion of the knowledge and beliefs of an agent, and the processing of new information by an agent. An e...

The evolution of belief systems has always been a focus of cognitive research. In this paper, we delineate a new model describing belief systems as a network of statements considered true. Testing the model with a small number of parameters enabled us to reproduce a variety of well-known mechanisms ranging from opinion changes to development of psychological problems. The self-organizing opinio...
