An assessment of regulation, education practices and socio-economic perceptions of non-native aquatic species in the Balkans

2021

Alongside climate change, the introduction of non- native species (NNS) is widely recognized as one of the main threats to aquatic biodiversity and human wellbeing. Non-native species and biodiversity are generally low priority issues on the political agendas of many countries, particularly in European countries outside the European Union (EU). The objectives and tasks of this study were to address the policy regulation, education level, education practices, and socioeconomic perceptions of NNS in the Balkans. A questionnaire based survey was conducted in Albania, Bosnia and Herzegovina, Montenegro, North Macedonia and Turkey (Balkan EU candidate and potential candidate members), in Croatia…

A calculus for robot inner speech and self-awareness

2019

The inner speech is the common mental experience the humans have when they dialogue with themselves. It is widely acknowledged that inner speech is related to awareness and self-awareness. The inner speech reproduces and expands in the mind social and physical sources of awareness. In this preliminary work, a calculus based on a first-order modal logic to automate inner speech is presented. It attempts to make the existing inner speech theories suitable for robot. By making robot able to talk to itself, it is possible to analyze the role of inner speech in robot awareness and self-awareness, opening new interesting research scenarios not yet investigated.

Multisensor Data Fusion in Pervasive Artificial Intelligence Systems

Intelligent systems designed to manage smart environments exploit numerous sensing and actuating devices, pervasively deployed so as to remain invisible to users and subtly learn their preferences and satisfy their needs. Nowadays, such systems are constantly evolving and becoming ever more complex, so it is increasingly difficult to develop them successfully. A possible solution to this problem might lie in delegating certain decisions to the machines themselves, making them more autonomous and able to self-configure and self-manage. This work presents a multi-tier architecture for a complete pervasive system capable of understanding the state of the surrounding environment, as well as usi…

Context-awareness for multi-sensor data fusion in smart environments

2016

Multi-sensor data fusion is extensively used to merge data collected by heterogeneous sensors deployed in smart environments. However, data coming from sensors are often noisy and inaccurate, and thus probabilistic techniques, such as Dynamic Bayesian Networks, are often adopted to explicitly model the noise and uncertainty of data. This work proposes to improve the accuracy of probabilistic inference systems by including context information, and proves the suitability of such an approach in the application scenario of user activity recognition in a smart home environment. However, the selection of the most convenient set of context information to be considered is not a trivial task. To thi…

Memoria e coscienza storiografica nella “praefatio” all’«Ystoriola Langobardorum Beneventum degen-tium» di Erchemperto

2023

In this intervention the reading of the "praefatio" at the «Ystoriola Langobardorum Beneventum degentium» by Erchempert, a Lombard historian of the IXth century, is conducted. The examination allows us to observe, as a preliminary, a historian of the High Middle Ages at his “work table”, in the reference to the sources and models and, at the same time, in the clear awareness of the innovative elements that he proposes to highlight through the story of the tragic and fatal decline of the Lombard people of southern Italy. To this are added other connotations that refer to a precise historiographical awareness, such as the high judgment of himself, the profession of truthfulness of the narrati…

Apprendere una seconda lingua da analfabeti tra ricerca e didattica. Una esperienza con i minori stranieri non accompagnati a Palermo

This contribution presents data and experiences acquired within the frame of the “Inclusion Project Linguistic School of Italian Language for Foreigners” of the University of Palermo. The program, created five years ago, has designed and managed educational courses for adults and unaccompanied minors (msna) of low and very low schooling level, most of them between 16 and 18 years old, and developed a series of social initiatives related to the insertion of these minors in Sicilian Society. These youths are part of a large number of unaccompanied adolescents who, in recent years, have come ashore to the port of Palermo along with thousands of refugees and asylum seekers. A significant number…

L’importanza dei prerequisiti e dello screening precoce nella scuola dell’infanzia

2016

Questo contributo si propone di sottolineare l’importanza di alcune competenze cognitive, detti prerequisiti, che sono implicate nell’acquisizione delle abilità di lettura e scrittura come ad esempio: la conoscenza dell’alfabeto; la consapevolezza fonologica; la denominazione rapida automatica (RAN); la memoria fonologica e la processazione visiva. Numerose ricerche, anche internazionali, mostrano l’importanza dell’esercizio di tali abilità all’interno della scuola dell’infanzia anche ai fini della prevenzione dello sviluppo di difficoltà di apprendimento e/o di veri e propri disturbi nella successiva carriera accademica del bambino. Inoltre, la realizzazione di interventi didattici mirati …

Channel Gain Cartography via Mixture of Experts

2020

In order to estimate the channel gain (CG) between the locations of an arbitrary transceiver pair across a geographic area of interest, CG maps can be constructed from spatially distributed sensor measurements. Most approaches to build such spectrum maps are location-based, meaning that the input variable to the estimating function is a pair of spatial locations. The performance of such maps depends critically on the ability of the sensors to determine their positions, which may be drastically impaired if the positioning pilot signals are affected by multi-path channels. An alternative location-free approach was recently proposed for spectrum power maps, where the input variable to the maps…

Aerial Spectrum Surveying: Radio Map Estimation with Autonomous UAVs

2020

Radio maps are emerging as a popular means to endow next-generation wireless communications with situational awareness. In particular, radio maps are expected to play a central role in unmanned aerial vehicle (UAV) communications since they can be used to determine interference or channel gain at a spatial location where a UAV has not been before. Existing methods for radio map estimation utilize measurements collected by sensors whose locations cannot be controlled. In contrast, this paper proposes a scheme in which a UAV collects measurements along a trajectory. This trajectory is designed to obtain accurate estimates of the target radio map in a short time operation. The route planning a…

Social Media Data in an Augmented Reality System for Situation Awareness Support in Emergency Control Rooms

2021

AbstractDuring crisis situations, emergency operators require fast information access to achieve situation awareness and make the best possible decisions. Augmented reality could be used to visualize the wealth of user-generated content available on social media and enable context-adaptive functions for emergency operators. Although emergency operators agree that social media analytics will be important for their future work, it poses a challenge to filter and visualize large amounts of social media data. We conducted a goal-directed task analysis to identify the situation awareness requirements of emergency operators. By collecting tweets during two storms in Germany we evaluated the usefu…
