Deposits of clastic carbonate-dominated (calciclastic) sedimentary slope systems in the rock record have been identified mostly as linearly-consistent carbonate apron deposits, even though most ancient clastic carbonate slope deposits fit the submarine fan systems better. Calciclastic submarine fans are consequently rarely described and are poorly understood. Subsequently, very little is known especially in mud-dominated calciclastic submarine fan systems. Presented in this study are a sedimentological core and petrographic characterisation of samples from eleven boreholes from the Lower Carboniferous of Bowland Basin (Northwest England) that reveals a >250 m thick calciturbidite complex deposited in a calciclastic submarine fan setting. Seven facies are recognised from core and thin section characterisation and are grouped into three carbonate turbidite sequences. They include: 1) Calciturbidites, comprising mostly of highto low-density, wavy-laminated bioclast-rich facies; 2) low-density densite mudstones which are characterised by planar laminated and unlaminated muddominated facies; and 3) Calcidebrites which are muddy or hyper-concentrated debrisflow deposits occurring as poorly-sorted, chaotic, mud-supported floatstones.

Pellet: A practical OWL-DL reasoner

Data integration is the problem of combining data residing at different sources, and providing the user with a unified view of these data. The problem of designing data integration systems is important in current real world applications, and is characterized by a number of issues that are interesting from a theoretical point of view. This document presents on overview of the material to be presented in a tutorial on data integration. The tutorial is focused on some of the theoretical issues that are relevant for data integration. Special attention will be devoted to the following aspects: modeling a data integration application, processing queries in data integration, dealing with inconsistent data sources, and reasoning on queries.

Data integration: a theoretical perspective

Emergency and exploration missions are accomplished by remote stationary personnel and on-site responders that can deploy robots for dealing with situations involving hazard or inaccessibility. Thus, human-robot interaction (HRI) plays a key role in these kinds of applications. Intra-scenario operator mobility is often considered to be advantageous for acquiring situational awareness (SA) in the context of robot teleoperation, but non portable devices can provide a greater volume of processed information. This should not be discounted when trying to build more effective human-robot interaction (HRI) in search and rescue (SAR) or exploration missions. In this paper, we report a set of experiments comparing a desktop-based interface with a PDA-based interface for remote control of mobile robots. Our goal is twofold. First we aim at defining which kinds of operators have the best SA under different conditions. Second, we investigate a control transfer policy for determining when an operator should hand over to another, depending on the device, the task and the context.

Robots that are launched in the consumer market need to provide more effective human robot interaction, and, in particular, spoken language interfaces However, in order to support the execution of high level commands as they are specified in natural language, a semantic map is required Such a map is a representation that enables the robot to ground the commands into the actual places and objects located in the environment In this paper, we present the experimental evaluation of a system specifically designed to build semantically rich maps, through the interaction with the user The results of the experiments not only provide the basis for a discussion of the features of the proposed approach, but also highlight the manifold issues that arise in the evaluation of semantic mapping

Interactive semantic mapping: Experimental evaluation

In large-scale, complex domains such as space defense and security systems, situation assessment and decision making are evolving from centralized models to high-level, net-centric models. In this context, collaboration among the many actors involved in the situation assessment process is critical to achieve a prompt reaction as needed in the operational scenario.

In this paper, we propose a multiagent-based approach to situation assessment, where agents cooperate by sharing local information to reach a common and coherent assessment of situations. Specifically, we characterize situation assessment as a classification process based on OWL ontology reasoning, and we provide a protocol for cooperative multiagent situation assessment, which allows the agents to achieve coherent high-level conclusions. We validate our approach in a real maritime surveillance scenario, where our prototype system effectively supports the user in detecting and classifying potential threats; moreover, our distributed solution performs comparably to a centralized method, while preserving independence of decision makers and dramatically reducing the amount of communication required. © 2012 Wiley Periodicals, Inc. © 2012 Wiley Periodicals, Inc.

Cooperative situation assessment in a maritime scenario

Policy gradient learning for quadruped soccer robots

In this paper a framework for an airport ground traffic surveillance system based on visual information is presented. The framework is designed to improve state-of-the-art Advanced Surface Movement Guidance and Control Systems (A-SMGCS) adding an image processing module able to act as a “gap-filler” for airport zones that traditional systems fail to reliably cover due to reflections and blind spots. Results of the approach based on a set of videos is presented demonstrating that the proposed framework is a flexible and cost-effective solution for improving existing systems' performance.
