An algorithm for fusing the alerts produced by multiple heterogeneous intrusion detection systems is presented. The algorithm runs in realtime, combining the alerts into scenarios; each is composed of a sequence of alerts produced by a single actor or organization. The software is capable of discovering scenarios even if stealthy attack methods, such as forged IP addresses or long attack latenc...

The academic picture of a globalized European countryside, and particularly rural areas in postsocialist, new member states the Union, is one huge increasing complexity, diversity, uncertainties about future. aim this research to construct alternative scenarios for Croatia 2030, acknowledging its postsocialist transition as an important framework. Future development were constructed by integrat...

The objective of this paper is to describe the process through which climate change scenarios were downscaled in an urban land use model and the results of this experimentation. The land use models (Urban Growth Model [UGM] and the Land Cover Deltatron Model [LCDM]) utilized in the project are part of the SLEUTH program which uses a probabilistic cellular automata protocol. The land use change ...

This paper presents a logic programming approach, based on the Event Calculus (EC), for representing and reasoning about triggered scenarios (TS), an expressive dialect of message sequence charts widely employed in software requirements engineering to specify system behaviour. We introduce a sound translation for triggered scenarios into an EC-based Answer Set Programming (ASP) representation, ...
