This work explores the benefits of using user models for plan recognition problems in a real-world application. Selfinterested agents are designed for the prediction of resource usage in the UNIX domain using a stochastic approach to automatically acquire regularities of user behavior. Both sequential information from the command sequence and relational information such as system’s responses an...

This survey is mainly motivated by the increased availability and use of panoramic image acquisition devices, in computer vision and various of its applications. Different technologies and different computational models thereof exist and algorithms and theoretical studies for geometric computer vision (“structure-from-motion”) are often re-developed without highlighting common underlying princi...

The River Basin Authority of Basilicata (AdB) is an interregional agency dealing with land protection and the planning of water resources. Its territory (which covers an area of about 9000 km in the south of Italy) is very abundant in environmental resources, but also very fragile and extremely rich in hydrogeological disturbances such as landslides and floods, due to its geological, geomorphol...

We discuss coupling from the past techniques (CFTP) for perturbations of interacting particle systems on Z with a finite set of states, within the framework of the graphical construction of the dynamics based on Poisson processes. We first develop general results for what we call CFTP times with ambiguities. These are analogous to classical coupling (from the past) times, except that the coupli...

In this paper, we optimize the search and rescue (SAR) in disaster relief through agent-based simulation. We simulate rescue teams’ search behaviors with the improved Truncated Lévy walks. Then we propose a cooperative rescue plan based on a distributed auction mechanism, and illustrate it with the case of landslide disaster relief. The simulation is conducted in three scenarios, including “fat...

The problem addressed here can be concisely formulated as follows: Given a stable surface orientation with a known reconstruction and given a direction in the plane of this surface, find the atomic structure of the steps oriented along that direction. We report a robust and generally applicable variable-number genetic algorithm for determining the atomic configuration of crystallographic steps,...

Population Identity: Based on studies of mitochondrial DNA, Cook Inlet belugas are genetically distinct from the other four beluga populations that occur in western and northern Alaska (O’Corry-Crowe et al. 1997; O’Corry-Crowe, pers. comm.). There have been only two beluga sightings recorded in the region between Cook Inlet and the nearest beluga population in Bristol Bay (Frost and Lowry 1990;...

Timeline-based planning techniques have demonstrated wide application possibilities in heterogeneous domains. However, a problem for a wider diffusion of such technology still stems in the reduced community that has been studying formal properties of this planning approach. In this sense, we are currently studying the connection between plan generation and execution from the particular perspect...
