Uncertainty in conceptual model structure and in environmental data is of essential interest when dealing with uncertainty in water resources management. To make quantification of uncertainty possible is it necessary to identify and characterise the uncertainty in geological and hydrogeological data. This paper discusses a range of available techniques to describe the uncertainty related to geo...

Cyber security is an interdisciplinary area that focuses on maintaining and reducing risks to the confidentiality, integrity, and availability of information and resources in computer and network systems. The complexity of modern systems and the diversity of threat vectors both social and technical, require intelligent, adaptive, multimodal solutions for which artificial intelligence approaches...

Automatic target recognition (ATR) is a computationally intensive problem that benefits from the abilities of the Connection Machine (CM), a massively parallel computer used for data-level parallel computing. The large computational resources of the CM can efficiently handle an approach to ATR that uses parallel stereo-matching and neural-network algorithms. Such an approach shows promise as an...

This article presents an algorithmic reconfiguration model, combining mechanisms of load balancing and fault tolerance in order to increase utilization of computer resources in a distributed multi-server, multitasking environment. The model has been empirically tested in a network of computers controlling telecommunication hubs and is compared to previous efforts to address this challenge.

Intrusions in computing environment are a very common undesired malicious activity that is going on since the inception of computing resources. A number of security measures have taken place for the last three decades, but as Technology has grown up, so as the security threats. With the whole world depending on computers, being directly or indirectly, it is a very important issue to prevent the...

This article proposes LOCARN: an alternative network architecture providing a packet connectivity layer, which is able to self-adapt its routing paths opportunistically according to both the network resources changes and the effective traffics fluctuations. Moving close to a global maximization of available resources usage and assuming high resiliency under failures, LOCARN focuses on component...

This paper reviews the growth behavior of a popular peer-to-peer network. We propose a dynamic hypothesis that the growth, overshoot, and collapse trajectories may be the result of complex causal interactions between inadequate resources, private provision of common goods, free riding, and membership dynamics. We draw parallels with other systems that are well-understood and known to exhibit si...
