Abstract: 3D contents have great potential in improving the communication and fruition of Cultural Heritage (CH). The visiting experience on an archaeological site or historical building can be improved by digital contents that help visitors to discover and learn how they once appeared. Augmented Reality (AR) is one of the technologies nowadays used for CH exploitation and it has the great quality of superimposing digital contents on elements of the reality. This paper shows a new interactive application on the archaeological site of Forum Sempronii: thanks to SLAM technology it allows the visitors to see several virtual reconstructions superimposed on the ruins walking around the site, so that they can see how anciently the roman city was. Great attention has been given to the creation of 3D contents: after the creation of high poly models they have been decimated and optimized in terms of number of polygons and textures in order to be fluently managed on mobile devices. The fruition of real scale contents on the real context increases immersive users’ experiences.

Abstract: Personal Health Systems (PHS) are mobile solutions tailored to monitoring patients affected by chronic non communicable diseases. In general, a patient affected by a chronic disease can generate large amounts of events: for example, in Type 1 Diabetic patients generate several glucose events per day, ranging from at least 6 events per day (under normal monitoring) to 288 per day when wearing a continuous glucose monitor (CGM) that samples the blood every 5 minutes for several days. Just by itself, without considering other physiological parameters, it would be impossible for medical doctors to individually and accurately follow every patient, highlighting the need of simple approaches towards querying physiological time series. Achieving this with current technology is not an easy task, as on one hand it cannot be expected that medical doctors have the technical knowledge to query databases and on the other hand these time series include thousands of events, which requires to re-think the way data is indexed. Anyhow, handling data streams efficiently is not enough. Domain experts’ knowledge must be explicitly included into PHSs in a way that it can be easily readed and modified by medical staffs. Logic programming represents the perfect programming paradygm to accomplish this task. In this work, an Event Calculus-based reasoning framework to standardize and express domain-knowledge in the form of monitoring rules is suggested, and applied to three different use cases. However, if online monitoring has to be achieved, the reasoning performance must improve dramatically. For this reason, three promising mechanisms to index the Event Calculus Knowledge Base are proposed. All of them are based on different types of tree indexing structures: k-d trees, interval trees and red-black trees. The paper then compares and analyzes the performance of the three indexing techniques, by computing the time needed to check different type of rules (and eventually generating alerts), when the number of recorded events (e.g. values of physiological parameters) increases. The results show that customized jREC performs much better when the event average inter-arrival time is little compared to the checked rule time-window. Instead, where the events are more sparse, the use of k-d trees with standard EC is advisable. Finally, the Multi-Agent paradigm helps to wrap the various components of the system: the reasoning engines represent the agent minds, and the sensors are its body. The said agents have been developed in MAGPIE, a mobile event based Java agent platform.

Abstract: Telerehabilitation in older adults is most needed in the patient environments, rather than in formal ambulatories or hospitals. Supporting such practices brings significant advantages to patients, their family, formal and informal caregivers, clinicians, and researchers. This paper presents a focus group with experts in physiotherapy and telerehabilitation, debating on the requirements, current techniques and technologies developed to facilitate and enhance the effectiveness of telerehabilitation, and the still open challenges. Particular emphasis is given to (i) the body-parts requiring the most rehabilitation, (ii) the typical environments, initial causes, and general conditions, (iii) the values and parameters to be observed, (iv) common errors and limitations of current practices and technological solutions, and (v) the envisioned and desired technological support. Consequently, it has been performed a systematic review of the state of the art, investigating what types of systems and support currently cope with telerehabilitation practices and possible matches with the outcomes of the focus group. Technological solutions based on video analysis, wearable devices, robotic support, distributed sensing, and gamified telerehabilitation are examined. Particular emphasis is given to solutions implementing agent-based approaches, analyzing and discussing strength, limitations, and future challenges. By doing so, it has been possible to relate functional requirements expressed by professional physiotherapists and researchers, with the need for extending multi-agent systems (MAS) peculiarities at the sensing level in wearable solutions establishing new research challenges. In particular, to be employed in safety-critical cyber-physical scenarios with user-sensor and sensor-sensor interactions, MAS are requested to handle timing constraints, scarcity of resources and new communication means, crucial to providing real-time feedback and coaching. Therefore, MAS pillars such as the negotiation protocol and the agent's internal scheduler have been investigated, proposing solutions to achieve the aforementioned real-time compliance.

Abstract: Since Artificial Intelligence (AI) applications became mature, there has been growing interest in employing them into complex real equipment, especially in order to implement “Cyber-Physical Systems” (CPS). Since its dawn as a discipline, AI focused on simulating and reproducing human-like mental processes using formal structures, chasing the high-quality of reasoning. However, with the challenges posed by CPS, AI needs to take into account concrete real “timing performances” in addition to abstract reasoning about “time”. The AI definition of “intelligent agent” seems to perfectly apply to CPS. Nevertheless, to be real, intelligent agents need to deal with, reason about and act in time. This paper motivates such needs by deriving the roots of the definition of Real-Time Agent in Philosophy, Control Theory, and AI. Moreover, some examples are provided to demonstrate why Real-Time agents are required in the “real world” of CPS. The paper concludes listing the desiderata of Real-Time Agents, wishing for the convergence of Multi-Agents Systems and Real-Time Systems.

2018 Multi-agent systems' negotiation protocols for cyber-physical systems: Results from a systematic literature review

Abstract: Cyber Physical Systems (CPS) require a multitude of components interacting among themselves and with the users to perform automatic actions, usually under unpredictable or uncertain conditions. Multi-Agent Systems (MAS) have emerged over the years as one of the major technological paradigms regulating interactions and negotiations among autonomous entities running under heterogeneous conditions. As such, MAS have the potential to support CPS in implementing a highly reconfigurable distributed thinking. However, some gaps are still present between MAS' features and the strict requirements of CPS. The most relevant is the lack of reliability, which is mainly due to specific features characterizing negotiation protocols. This paper presents a systematic literature review of MAS negotiation protocols aiming at providing a comprehensive overview of their strengths and limitations, examining both the assumptions and requirements set during their development. While this work confirms the potential of MAS in regulating the interactions among CPS components, the findings also highlight the absence of real-time compliance in current negotiation protocols. Strongly characterizing CPS, the capability to face strict time constraints could bridge the gap between MAS and CPS

Abstract: Some recent trends in distributed intelligent systems rely extensively on agent-based approaches. The so-called Multi-Agent Systems (MAS) are taking over the management of sensitive data on behalf of their producers and users (e.g., medical records, financial investment, energy market). Therefore, trusted interactions are needed more than ever, while accountability and transparency among the agents seem crucial characteristics to be achieved. To do so, recent trends advocate the use of blockchain technologies (BCT) in MAS. The blockchain is a distributed ledger technology that can execute programmable transaction logic, and provides a shared, immutable, and transparent append-only register of all the actions happening in the network. Although a few theoretical approaches have already been proposed, the quest for such a system consolidating BCT and MAS to guarantee privacy, scalability, transparency, and efficiency continues. This paper presents a reconciling system including BCT within the dynamics of a MAS. Such a system aims at (i) building a solid ground for trusted interactions and (ii) enabling more characterizing feature-based and trustworthy ways of computing agent reputation. The system has been tested in four scenarios with different configurations (regular executions and involving down-agents or malicious behaviors). Finally, the paper summarizes and discusses the experience gained, argues about the strategic choice of binding MAS and BCT, and presents some future challenges

Abstract: Ambient assisted living (AAL) is focused on providing assistance to people primarily in their natural environment. Over the past decade, the AAL domain has evolved at a fast pace in various directions. The stakeholders of AAL are not only limited to patients, but also include their relatives, social services, health workers, and care agencies. In fact, AAL aims at increasing the life quality of patients, their relatives and the health care providers with a holistic approach. This paper aims at providing a comprehensive overview of the AAL domain, presenting a systematic analysis of over 10 years of relevant literature focusing on the stakeholders’ needs, bridging the gap of existing reviews which focused on technologies. The findings of this review clearly show that until now the AAL domain neglects the view of the entire AAL ecosystem. Furthermore, the proposed solutions seem to be tailored more on the basis of the available existing technologies, rather than supporting the various stakeholders’ needs. Another major lack that this review is pointing out is a missing adequate evaluation of the various solutions. Finally, it seems that, as the domain of AAL is pretty new, it is still in its incubation phase. Thus, this review calls for moving the AAL domain to a more mature phase with respect to the research approaches

Abstract: The complexity of cyber-physical systems (CPSs) poses new challenges in their design, model checking and maintenance. The hardware and software designers are in search, more than ever, for simple and interoperable approaches that render the complexity of CPSs a treatable matter. In this work, database language is suggested as an enabling technology and a lean technique to the purpose. An example with best available embedded database technology is conducted by means of a deployment test on tiny embedded electronics.

Abstract: The number of proposals involving ICT-based intelligent solutions for the Ambient Assisted Living (AAL) is continuously increasing. Thus, tests and a validation process are crucial for implementing effective systems. However, testing and validating software systems for the AAL in real environments are onerous and safety-critical tasks. Problems often arise when the software is being installed in a real smart home: unpredicted scenarios can occur, thus forcing the designer to perform complex fixing when it is too late. This paper proposes the adoption of a 3D simulator to speed up the development and testing phases of software for AAL systems, by restricting possible issues occurring during the tests in real scenarios. The paper describes the architecture of the simulator and the implemented virtual environment. Moreover, it presents a use case, highlighting how the simulator allows decoupling the software to manage a smart home from the hardware components

Abstract: We present a touchless interface based on gesture recognition for the control of an elevator. Interacting with the interface, a user can select and confirm the desired floor without touching any physical device. The interface has to guarantee a usability comparable to the habitual button panels: the users are supposed to use the elevator without any specific training, and its functionality has to be the same of traditional elevators. In addition to describing three possible implementations of the touchless interface, the paper provides two contributions: a comparison of two different technologies used as the interface inputs, and the results from 10 preliminary user tests performed to measure the perceived usability. The results are promising: two implementations out of three got an average score around 84 on the "Usability Metrics for User Experience"

Abstract: Robots interacting with human beings are widespread in modern environments, and those performing intelligent tasks without human supervision need to take into account potential criticalities. Making robots compete enable their evaluation with respect to navigation, mapping, object recognition, tracking and manipulation capabilities. Robot competitions date back to the early '80s proving to be useful for educational and research purposes. Several competitions are focused on human-robot interaction, even though they rarely produce as outcome robots capable to seamlessly interact with human beings. The main reason for this is the lack of understanding of human intentions and the failure to rapidly react to human actions. In other words, an ideal robot must be able to communicate and coordinate with humans or with other robots, to act autonomously, and to react under real-Time constraints. This paper proposes a new framework to simplify the development of intelligent robots, testing them in a real robot competition. The framework combines (i) a multi-Agent system to interact with humans, other robots and perform object identification and pathfinding, and (ii) a real-Time motion control deployed on the Erika RTOS, to move the robot and react in a timely fashion to changes in the environment. In the considered competition scenario, the robot is required to identify and collect common objects in a bounded arena with dynamic obstacles in a limited amount of time, receiving commands from humans and competing with other robots. This approach confirms the powerful combination of multi-Agent systems, computer vision, and real-Time systems.

2015 Towards multi-agent Health Information Systems
INTERNATIONAL JOURNAL OF E-HEALTH AND MEDICAL COMMUNICATIONS
Autore/i: Claudi, Andrea; Sernani, Paolo; Dragoni, Aldo Franco
Classificazione: 1 Contributo su Rivista
Abstract: One of the key challenges in the healthcare sector is to adapt Health Information Systems to requirements coming from changing societies. In recent years, governments and international healthcare organizations defined a series of requirements for new generation Health Information Systems: they have to preserve past investments on legacy systems, but must also integrate new technologies, include the patient among their users, and ensure that clinical information are available at all times, even in places far from where information are physically stored. This paper proposes a multi agent-oriented architecture for Health Information Systems, which uses international standards for communication and management of clinical documents. The architecture tries to effectively model a generic healthcare organization, and aims at being easily extensible and adaptable to the particularities of specific healthcare systems. The authors present two experimental scenarios to test the proposed multi-agent health information system. In the first, they show how to model a specific use case, a radiology workflow, using agents and well-known standards; in the second one the authors demonstrate how a mobile application can use the services provided by the agents to support the medical staff in an emergency situation.

2015 Combining Artificial Intelligence and NetMedicine for Ambient Assisted Living: A distributed BDI-based expert system
INTERNATIONAL JOURNAL OF E-HEALTH AND MEDICAL COMMUNICATIONS
Autore/i: Sernani, Paolo; Claudi, Andrea; Dragoni, Aldo Franco
Classificazione: 1 Contributo su Rivista
Abstract: World population is shifting towards older ages: according to recent estimates there will be 1.5 billion people over 65 years old in 2050. Local governments, international institutions, care organizations and industry are fostering the research community to find solutions to face the unprecedented challenges raised by population ageing. A combination of Artificial Intelligence and NetMedicine could be ideal to face these challenges: they provide the means to develop an intelligent system and simultaneously to distribute it over a network, allowing the communication over the internet, if needed. Hence, the authors present a Multi-Agent Architecture for Ambient Assisted Living (AAL): it is the model for a system to manage a distributed sensor network composed by ambient and biometric sensors. The system should analyse data and pro-active ly decide to trigger alarms if anomalies are detected. The authors tested the architecture implementing a prototypical Multi-Agent System (MAS), based on Belief-Desire-Intention (BDI) paradigm: the Virtual Carer

Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: Despite the progress in ambient assisted living (AAL), the general audience is still mostly unaware of this term as well as of its purpose, enabling technologies, and potential. As a consequence, there are often misconceptions about AAL and smart homes, and the acceptance of AAL technologies is still too low. To cope with these problems, this paper presents a publicly available awareness game called Smart Tales, whose goal is to enhance the familiarity of its players with the notion and core concepts of AAL. In Smart Tales, the player has the role of an assisted patient in a smart home, and gets to learn about AAL and its technologies while trying to cheat the sensors that are placed in the house. In addition to presenting the design of the game following the Serious Games Design Assessment framework from the literature, we present results on engagement and learning that we obtained through a formative evaluation with ten users.

Abstract: Ambient Assisted Living (AAL) and Ambient Intelligence (AmI) aim at building safe, smart and interconnected environments around people. Nevertheless, the testing phase of intelligent software systems managing smart homes, in real environments, requires an enormous effort in terms of time, work and money. With this paper, we discuss the possibility to use 3D virtual environments during the developing and preliminary tests of such systems, as it happens in robotics with 3D simulators. Even if this approach cannot totally replace the need of real user trials, it can speed up the implementation of prototypes, decoupling software from hardware.

Abstract: Obstacle detection is one of the most important tasks for mobile robots moving along a plane, and it is critical to avoid damages, either to the robot or to human operators. In the past decades, several techniques were proposed for visual navigation of mobile robots, relying on different kind of sensors and algorithms: sonar sensors, laser stripes, and stereo vision are commonly used techniques. Even if these techniques are well-established and used in commercial robots, different and better sensors are now widespread, such as depth sensors. This work proposes an algorithm based on the use of an active 3D depth sensor for obstacle detection and avoidance. The algorithm, conceived to be used in embedded systems with low processing power, underwent several experiments and proved to be robust to Gaussian white noise.

Abstract: As a requirement engineering technique i* has been used to model requirements for a single system. In this paper, we consider whether i* can be used to explore and map user needs and requirements for an entire application domain rather than for a single system. A domain-wide requirements model can be used to assess the suitability of various technology architectures and solutions for that domain. The domain of Ambient Assisted Living (AAL) is characterized by a large variety of stakeholders with different professional and socio-cultural backgrounds. The domain is highly heterogeneous and thus suitable for our purpose of demonstrating domain exploration. We discuss the challenges in mapping that domain, and our attempts to adapt i* concepts and usage for this purpose.

Abstract: This article describes projects in the domain of artificial intelligence and law, which resulted from the research of the five authors listed, when they formed teams (of the first author named and each one of the other authors). Therefore, the present paper offers a subjective perspective, from the viewpoint of personal trajectories within AI & Law. Several, though not all, of the projects concerned dealt with facets of legal evidence. These projects include: ALIBI (an AI planner generating exonerating accounts); a representation of Italy’s regional constitutions in a nested-relation representation (a precursor of XML); the application of kappa calculus and a probabilistic interpretation to a Scandinavian approach to evidential strength; the application of Petri Nets for representing temporal relations in mutual wills; Daedalus (Judge Asaro’s software assisting Italy’s examining magistrates with inquiries, and then when they turn prosecutors); a study in occurrences in court of allegations echoing the pretext archetype “The dog ate my homework” (even when the claim was not pretextuous); an application of Wigmore Charts to an analysis of both the argumentation and the rhetoric of an Italian arringa (final submissions to the court) from a real court case; editorial projects which promoted the emergence of evidence as a conspicuous field within AI & Law (thus overturning previous neglect); and a magnum opus (Nissan 2012a) which presents the state of the art of computational applications to legal evidence, police inquiries, or argumentation.

Abstract: A shift in the distribution of population towards older ages is occurring in almost every country of the world and it is becoming a major problem in Europe, Japan and USA, due to the high dependency ratio of these countries. Ambient Assisted Living (AAL) and Ambient Intelligence (AmI) are polarising the attention of the research community, trying to improve the quality of life of elderly people promoting their autonomy, self-confidence and mobility. Artificial Intelligence (AI), developing intelligent and adaptable systems, can play a considerable role in AAL and AmI to cope with the changing needs that characterize the life of people with chronic diseases. To show a possible contribution of AI in these fields, this paper introduces the multi-agent architecture of an expert system for Ambient Assisted Living: the Virtual Carer (VC). Based on the Belief-Desire-Intention (BDI) paradigm, it models the behaviours of a human caregiver. The main goal of the Virtual Carer is to help an elderly patient in his daily activities, while his health conditions are monitored, in order to ensure his security. To show the main capabilities of the system, the paper describes some simulations of the proposed agency, highlighting the architecture of the reasoning component.

Abstract: Due to the aging of the population western world need technological solutions to improve the quality of life of the elderly/disabled people, helping them to stay independent and autonomous at home. Technologies for e-health need to be tested on real before going to the market. Unfortunately, testing solutions for “Active Assisted Living” in a domotic house requires an enormous effort in terms of work, time and money, especially because we’d need to test them with real inhabitants. Therefore we developed a 3D simulator for AAL, with the goal to model different virtual scenarios, controlled in an autonomous way by a virtual caregiver able to take decisions from information received from the sensors/inhabitants, and able to return an output in the form of services. The interface with the simulator is provided by a mobile application, while the built-in sensors of the smartphone make it an element that integrates the simulated environment.

Abstract: The Ambient Assisted Living (AAL) domain is associated with a large number of stakeholders such as patients, their relatives, caregivers and physicians. This variety introduces a great heterogeneity in system requirements, which sometimes results in conflicting needs that must be considered when developing effective AAL systems. In this work we adopt a Goal-Oriented Requirements Engineering (GORE) approach to map out needs and requirements for the AAL domain. Following the requirements mapping, we also propose a preliminary architecture for a home care system (named e-Ward) to assist patients in their domestic environment as if they are in a hospital room.

Abstract: Cyber-physical systems are now widespread in applications of paramount importance, from traffic control to healthcare and robotics applications. Modelling cyber-physical systems making use of artificial intelligent methodologies is very difficult, because of unpredictability in AI algorithms timing performances. This paper proposes a methodology to model Intelligent Cyber-Physical Systems, relying on hierarchical hybrid models. The proposed modelling method is used to develop an autonomous robot for face-detection and face-recognition, and some experiments were proposed to validate its performances. © 2013 University of Applied Science, Regensburg.

Abstract: The interest towards biometric approach to identity verification is high, because of the need to protect everything that could have a value for some purpose. Face recognition is one of these biometric techniques, having its greater advantage in requiring a limited interaction by user. We present a Face Recognition System (FRS) based on multiple neural networks using a belief revision mechanism. Each network is associated to an a-priori reliability value for each identity stored in database, modelling the specific skill of the modules composing the system with the recognition of a given subject. Every time a network is in conflict with the global response, it is forced to retrain itself, subjecting the system to a continuous learning. The main goal of this work is to carry out some preliminary tests to evaluate accuracy and robustness of FRS with “subject-dependent” reliability values, when some changes can affect the considered features. Tests over digitally aged faces are also conducted.

Abstract: The healthcare domain is wide and characterized by system and data herogeneity. To achieve high quality and efficiency standards, interoperability between different information systems is strongly required. The aim of this paper is to propose an agent oriented architecture to address this kind of issues, which is compliant with the European Union (EU) guidelines and with requirements issued by the italian Ministry of Health. To validate and to show the capabilities of our system, we developed on such architecture a typical emergency-response scenario, where a first aid medical staff urgently needs to retrieve, through mobile devices, the Patient Summary (PS) of a citizen, which is part of his Electronic Health Record (EHR).

Abstract: The GSM voice channel is the world's most widely used mobile communication network. Unfortunately these networks are affected by serious vulnerability from hardware-based attacks and communications can be easy to intercept. This paper describes a prototype implementation of a device which enables secure data and voice transmission over GSM voice channel network. The proposed system is supposed to interact with every cell phone or mobile device connected to the GSM network, differentiating itself from the best-known crypto-phone category. In the following, we will highlight the particular modulation strategy used to generate a specific wave-form that allows the receiver to correctly decipher data with a very low BER. In conclusion, this work aims to define the principles to model a secure infrastructure over a GSM network.

2013 Universal Access to Health Services Through the Digital Terrestrial Television
JOURNAL OF INFORMATION TECHNOLOGY RESEARCH
Autore/i: Dragoni A. F.
Classificazione: 1 Contributo su Rivista
Abstract: The Western World has almost completed the transition toward the Digital Television (DTV), and in particular toward the Digital Terrestrial Television (DTT). In every home there is at least one decoder for the DTT. Some of them have a modem, to connect to a telephonic return line, and a Smart Card reader, both required by the “Pay TV” channels. Since those readers are compatible with the Governmental Smart Cards, a new access for the masses to secure and confidential digital services is nowadays available in our Information Society. “T-Government” defines the set of services provided by Governments or private entities via DTT. “Multimedia Home Platform” is the standard for DTT applications. A Local Health will be no more justified for offering services only through the Web disregarding both the broadcast and the return channels of the DTT since by doing so it would contribute to deepen the “digital divide” between skilled (young) people and unskilled (elder) people. The author defines a scenario for providing such T-Health Services both for patients (T-monitoring health parameters) and healthy citizens. These latter will have a bunch of services over DTT, not only informative or interactive applications on the Set top Box, but also transactional services through the secure return channel. However, much effort has to be spent to guarantee the usability of that new interface which is quite different from that of a Web application. The author designed, tested and redesigned a suite of DTT applications as a “proof of concept” to show the potential of this new platform for health information services. DTT may represent a real contribution to bring social healthcare and wellness.

Abstract: The ageing process of population of the First World countries is increasing the interest towards solutions to improve the quality of life of elderly or disabled people and their families, providing an economically sustainable healthcare. Thus Ambient Assisted Living (AAL) and Ambient Intelligence (AmI) are moving towards the Artificial Intelligence field to develop modular, adaptable and intelligent systems to cope with changing needs that characterize the life of people with chronic diseases. These systems should find smart and simple ways to improve the patient quality of life, enhancing at the same time the communication between the system, the assisted person, his family and the medical staff, acting also as a filter of information that provides useful and significant data. This paper introduces the basic architecture of an expert system for AAL: the Virtual Carer (VC). It has to be understood as an IT system modelling a distributed, reliable and modular sensor network composed by biometric and ambient sensors, being able to communicate with an assisted person, to monitor his health conditions and to control the environment around him. The main goal of the system is to help an elderly patient with his daily activities ensuring his security. The proposed system is based on a multi-agent architecture to ensure its flexibility and interoperability: new devices or sensors can be added simply adding new agents, thanks to the standardization of agent communication. The system includes also a reasoning part based on Belief-Desire-Intention (BDI) paradigm, trying to model the behaviours of a human caregiver.

Distribution, high modularity, robust- ness are features of agent oriented architectures, making Multi- Agent Systems (MAS) ideal for Health Information Systems (HIS), as the healthcare domain is characterized by system and data heterogeneity. This paper presents an agent oriented architecture to address this kind of issues, capable to access geographically distributed data to allow health professionals to retrieve/update any patient’s record efficiently and reliably. The proposed architecture is composed by three layers, to allow local data storage keeping clinical information available by authorized facilities and physicians.

Abstract: In view of the rapidly progressive increase in the average population age, “Ambient Assisted Living” (AAL) defines the actions and policies needed to promote the improvement of living conditions within domestic spaces to foster autonomy, safety and social inclusion for the elderly or disabled. The idea is to design an innovative and comprehensive information system for AAL, an ICT-based “Virtual Caregiver”, which is informed, intelligent and friendly, and which constantly monitors the health warning, informing and advising the elderly while controlling the environment and then asking for help when needed. The system will have the ability to establish interactive communication with the person but also extend it automatically outside the house in times of need. Virtual Caregiver will be able to enable the software protocols that activate the emergency phone calls to the family, medics or even first aid in emergencies.

Abstract: The use of automated surveillance systems is common in several application domains, from transport and commerce to military. Surveillance systems evolved through the years: first and second generation systems use fixed or semi-mobile cameras, while third generation systems make use of autonomous robots. This way intelligent surveillance systems turn into distributed systems, and their configuration can vary to take into account particular environmental conditions or to compensate for one or more malfunctioning sensors. This paper describes MARVIN, a mobile autonomous robot to be used in a video surveillance system. Using well-established face-detection and face-recognition methods, MARVIN can track and follow human faces in the monitored environment. This paper proposes also an experimental evaluation of the real-time performances of the system, under conditions specified in a well-defined reference scenario.

One or more neural nets could no longer be able to properly operate, due to partial changes in some of the characteristics of the individuals. We assume that each network has a reliability factor that can be dynamically re-evaluated on the ground of the global recognition operated by the overall group. Since the net's degree of reliability is defined as the probability that the net is giving the desired output, in case of conflicts between the outputs of the nets the re-evaluation of their degrees of reliability can be simply performed on the basis of the Bayes Rule. The new vector of reliability will be used for making the final choice, by applying two algorithms, the Inclusion based and the Weighted one over all the maximally consistent subsets of the global outcome

Abstract: An ontology is a representation in a logical language of a domain. An ontology can change; a changing ontology can became inconsistent, thus preventing its further use for machine reasoning. We analyze what an ontology is from a computer science perspective, why it can change, and how to manage inconsistency in changing ontologies. The belief revision approach is not the only possible approach to maintain consistency during evolution: an ontology reengineering can rationally prefer to discard incoming information, or to refine the nature of conflicting implication axioms to derive meaningful answer from inconsistent ontology using paraconsistent logic.

Abstract: Surveillance systems frequently use fixed or semimobile cameras. However, in many cases, the use of intelligent mobile sensors is preferrable over fixed sensors, because the system configuration can be modified according to particular environmental conditions or adapted to compensate for one or more malfunctioning sensors. This paper proposes a real-time surveillance system based on a mobile sensor. Using an Android smartphone and a face-tracking algorithm, the system can move autonomously to track the human face with the longest presence in the video field. In addition, the system can be connected to a computer performing face-recognition through a wireless connection provided by the smartphone. This way the mobile sensor can track a determined human face. The paper provides some experimental results to validate system performance.

Testing is even more important in real-time systems, because they are used in environments where a single failure could lead to serious damages. The first efforts to change the Linux kernel, introducing in it some real-time features, are dating back more than ten years ago. Nevertheless, up to now there's not a comprehensive test suite able to assesses the functionality and the conformance to the real-time operating systems standards for the Linux kernel and for the real-time nanokernels that rely on it. This paper discusses an ongoing work on Lachesis, an automated test suite for real-time Linux features. Lachesis's main goals are: to provide a standard and simple API to develop new tests; to provide a set of functional, regression, performance and stress test, either developing or porting them from other test suites; to design and experiment a series of build tests; to make the test suite extensible and portable. Up to now Lachesis is used to test Linux, PREEMPT RT, RTAI and Xenomai real-time features and performances. It provides some tests for SCHED DEADLINE patch, too. Lachesis is under active development: extensions to other real-time systems and more tests are planned to be added in the near future

2011 A Continuos Learning for a Face Recognition System
Proceedings of the 3rd International Conference on Agents and Artificial Intelligence
Autore/i: DRAGONI A.F.; VALLESI G; BALDASSARRI P.
Classificazione: 4 Contributo in Atti di Convegno (Proceeding)
Abstract: A system of Multiple Neural Networks has been proposed to solve the face recognition problem. Our idea is that a set of expert networks specialized to recognize specific parts of face are better than a single network. This is because a single network could no longer be able to correctly recognize the subject when some characteristics partially change. For this purpose we assume that each network has a reliability factor defined as the probability that the network is giving the desired output. In case of conflicts between the outputs of the networks the reliability factor can be dynamically re-evaluated on the base of the Bayes Rule. The new reliabilities will be used to establish who is the subject. Moreover the network disagreed with the group and specialized to recognize the changed characteristic of the subject will be retrained and then forced to correctly recognize the subject. Then the system is subjected to continuous learning.

2011 La Riviera delle Palme su Internet
Autore/i: A. F. Dragoni; F. Isopi; G. Vallesi
Luogo di pubblicazione: Roma
Classificazione: 5 Altro
Abstract: Internet ha modificato l’organizzazione del turismo riducendone l’intermediazione. Il web, grazie alla sua natura ipermediale sovranazionale è diventato “Il" luogo per eccellenza dove posizionare l'offerta turistica, non solo in quanto vetrina di prodotti ma anche come strumento d'erogazione di servizi transattivi. La Riviera delle Palme attrae da sempre turisti stranieri, ed i suoi operatori sono ogni giorno più attenti all’uso del web, ma la nostra sensazione era che la promozione rimanesse molto legata al passaparola ed alla fidelizzazione affettivo/familiare. Abbiamo quindi inteso effettuare un'analisi per valutare come si stia attrezzando la Riviera al cambiamento epocale in atto, confrontando il posizionamento su Internet della sua offerta turistica con quello della più importante riviera romagnola. Dal confronto nascono alcuni consigli su come far risalire le posizioni dei siti piceni piuttosto “sepolti" nei motori di ricerca: creazione di portali di categoria, innovazione siti esistenti, internazionalizzazione dei contenuti, cross-referencing e aggiornamento continuo.

Abstract: Testing is a key step in software development cycle. Error and bug fixing costs can easily exceed development costs without a full and comprehensive test on the system. First efforts to introduce real-time features in the Linux kernel are now more than ten years old. Nevertheless, no comprehensive testsuites is able to assess the functionality or the conformance to the real-time operating systems standards of the Linux kernel and of real-time nanokernels that rely on it. In this paper we propose Lachesis, an automated testsuite derived from the LTP (Linux Test Project) real-time tests. Lachesis main goals are: to provide extensive and comprehensive testing of real-time Linux features; to provide a set of functional, regression, performance and stress test, either developing or porting them from other testsuites; to design and experiment a series of build tests; to minimize development time for new tests; to make the testsuite extensible and portable. Lachesis can be used to test Linux, PREEMPT_RT, RTAI and Xenomai real-time features and performances. It provides some tests for SCHED_DEADLINE patch, too. Lachesis is now under active development: extensions to other real-time systems and more tests are planned to be added in the near future.

Abstract: Hepatic cancer is one of the most common solid cancers in the world. As surgery of hepatic cancer is seldom applicable, different solutions have been found to cure this disease. One of these is Liver Radiofrequency Ablation. This technique consists in a needle insertion inside the liver parenchyma in order to reach the tumor and in an injection of a radiofrequency current to cause tumor cell necrosis for hyperthermia. The needle placement task is really difficult because surgeon uses ultrasound, CT or MRI two-dimensional image to guide the needle. In this paper we present an Augmented Reality system to help the surgeon to place the needle as best as possible; the application can also help the surgeon during the preoperative planning because it offers various visualization modality of 3D models of the patient's organs obtained from the medical images

Abstract: We propose a Hybrid System for dynamic environments, where a “Multiple Neural Networks” system works with Bayes Rule to solve a face recognition problem. One or more neural nets may no longer be able to properly operate, due to partial changes in some of the characteristics of the individuals. For this purpose, we assume that each expert network has a reliability factor that can be dynamically re-evaluated on the ground of the global recognition operated by the overall group. Since the net’s degree of reliability is defined as the probability that the net is giving the desired output, in case of conflicts between the outputs of the various nets the re-evaluation of their degrees of reliability can be simply performed on the basis of the Bayes Rule. The new vector of reliability will be used to establish who is the conflict winner, making the final choice (the name of subject). Moreover the network disagreed with the group and specialized to recognize the changed characteristic of the subject will be retrained and then forced to correctly recognize the subject. Then the system is subjected to continuous learning.

Abstract: There are different proposals to extend RDF model theory allowing a treatment of uncertainty within the language. This works proposes a unified approach for RDF graph and statement labeling. This approach is more general than fuzzy and temporal labels and can be used to label RDF graphs with membership degrees, timestamps, or with a combination of labelings. Starting from a definition of labeled sets and labeled logic, we define labeled RDF and labeled RDF Schema. A partial ordering among labels allows qualitative treatment of uncertainty.

The MIRTES architecture and implementation focusing on data-centric services is here proposed together with its experimental validation. At the state of the art for data-centric middleware, packages succeed in providing a database like abstraction of the network supporting SQL-like queries spawned at Service Access Points hosted in high-end devices like PCs. Anyhow none of these packages tackles with the timeliness issue, being developed on top of non real-time technologies for operating systems and network protocols.

Abstract: A knowledge management system is more than an archive of textual documents; it provides context information, allowing to know which documents where used by people with a common goal. In the hypothesis that a set of textual documents with a common context can be assimilated to the long term memory of a human expert executor, we can use on them mining techniques inspired by the mechanic of human comprehension in expert domains. Text mining techniques for KM task can use a model of the long-term memory to extract meaningful keywords from the documents. The model acts as a dynamic and non-stationary dimensionality reduction strategy, allowing the clustering of context documents according to keyword presence, the classification of external documents according to local criteria, and a better understanding of document content and relatedness

Abstract: We propose a “Multiple Neural Networks” system for dynamic environments, where one or more neural nets may no longer be able to properly operate, due to sensible partial changes in the characteristics of the individuals. We assume that each expert network has a reliability factor that can be dynamically re-evaluated on the ground of the global recognition operated by the overall group. Since the net’s “degree of reliability” is defined as “the probability that the net is giving the desired output”, in case of conflicts between the outputs of the various nets the re-evaluation of their “degrees of reliability” can be simply performed on the basis of the Bayes Rule. The new vector of reliability will be used for making the final choice, by applying the “Inclusion based” algorithm over all the maximally consistent subsets of the global outcome. Finally, the nets recognized as responsible for the conflicts will be automatically forced to learn about the changes in the individuals’ characteristics and avoid to make the same error in the immediate future

Abstract: The purpose of the developed system is the realization of a gesture recognizer, applied to a user interface. We tried to get fast and easy software for user, without leaving out reliability and using instruments available to common user: a PC and a webcam. The gesture detection is based on well-known artificial vision techniques, as the tracking algorithm by Lucas and Kanade. The paths, opportunely selected, are recognized by a double layered architecture of multilayer perceptrons. The realized system is efficiency and has a good robustness, paying attention to an adequate learning of gesture vocabulary both for the user and for system.

Abstract: The main problem with iris biometric identification systems is the presence of noises in the image of the eye (eyelid, eyelashes, etc...). To remove it many authors apply appropriate preprocessing to the image, but unfortunately this yields losses of information. Our work aims at correctly recognizing the subject also in presence of high rates of noise. The basic idea is that of partitioning the image of iris into 8 not-interleaved segments of the same size. Each segment is given to an LVQ network which generates prototypes with a high resistance to noise. Notwithstanding this, the 8 LVQ nets may still disagree in identifying the subject. In this paper we apply a method developed by the "belief revision" community to identify conflicts and rearrange the degrees of reliability of each expert (the LVQ nets) through a Bayesian algorithm. This estimated ranking of reliability is useful to take the final decision.

Abstract: Quando nel 2012 la Televisione Analogica terminerà le trasmissioni ed i decoders del Digitale Terrestre (DT) saranno nelle case di tutti gli Italiani, gli Enti Pubblici non saranno più giustificati nel fornire informazioni e servizi solo su Internet. Anche le Aziende Sanitarie dovranno contribuire a ridurre questo “digital divide” portando sul DT le più importanti informazioni e servizi cogenti erogati attualmente tramite Internet. La “Multimedia Home Platform” del DT ha però caratteristiche protocollari e strutturali diverse, per cui è importante capire fin da ora come potranno essere trasportati contenuti dall'ambiente PC allo scenario televisivo, in cui la capacità d'interazione è ridotta dai limiti imposti dal telecomando. La presenza del “canale di ritorno” consentirà al cittadino di inviare richieste di servizi all'Azienda e ricevere risposte personali, garantendo quindi la specificità interattiva e la riservatezza

Abstract: The lines of action of the regional healthcare area “ASUR” of Ancona (Italy) try to reach the unity, not the uniqueness of the overall set of social and health services. According to the health integration plan, the programmatic indications coming from the Administrative Department have to find a concrete realization on the territory. This can be effectively done just involving all the public and private subjects which can assure the health integration. The collaborative learn- ing management system presented in this article is a communication platform that collects all the knowledge acquired by the social and health care operators promoting discussion spaces where innovative solutions for health integration can arise. These are structured as Integrated Care Pathways and undergo clinical trials before being accepted as organizational standards. The system is based on an organizational blogosphere, and social network analysis is used to identify the social and health care staff members which have the widest view of what happens within their organizations. These can be contacted for an interview by the regional Consulting and Service Centre for the Health Integration or they can be invited to open a discussion space on the main health integration problems.

Abstract: The paper describes a method for extracting hu man action semantics in video’s using queries-by-exam ple. Here we consider the indexing and the matching proble ms of content-based human motion data retrieval. The query formulation is based on trajectories that ma y be easily built or extracted by following relevant points on a video, by a novice user too. The so real ized trajectories contain high value of action semant ics. The semantic schema is built by splitting a trajecto ry in time ordered sub-sequences that contain the feat ures of extracted points. This kind of semantic representat ion allows reducing the search space dimensionality and, being human-oriented, allows a selective recogni tion of actions that are very similar among them. A neural network system analyzes the video semantic sim ilarity, using a two-layer architecture of multilayer perceptrons, which is able to learn the semantic schem a of the actions and to recognize them.

Abstract: Although Belief-Desire-Intention (BDI) agents have been deeply investigated from both a theoretical and a pragmatic perspective, less attention has been paid to the inherent recursive structure of mental states, which plays an essential role when modelling high level interaction between intelligent agents. This paper tries to capture this property by introducing a multi-context approach to the representation of mental states. A semantics for multi-context formalisms is provided based on the definition of “mental structure”, which is a hierarchical lattice of triangular modules , where the component x represents the agent x’s mental state as a whole, while B and D represent specifically x’s beliefs and x’s desires. If other mental attitudes, as intention and commitment, are to be considers as primitives, then they can be embodied in the basic module, otherwise they can be represented in terms of beliefs and desires. The old notion of clause is rediscovered in order to facilitate the heavy automated theorem-proving necessary to exploit the potentiality of the formalism for the intelligent interaction with the external environment. The main advantages of this approach are the support for “unconsciousness” and the fact that inferences themselves can be modelled as mental attitudes. Some advanced dynamics of mental states, as the abductive revision of mental states after the reception of a communication, will easily be applied over this formalism.

Abstract: Semantic Web languages cannot currently represent vague or uncertain information. However, their crisp model-theoretic semantics can be extended to represent uncertainty in much the same way first-order logic was extended to fuzzy logic. We show how the interpretation of an RDF graph (or an RDF Schema ontology) can be a matter of values, addressing a common problem in real-life knowledge management. While unmodified RDF triples can be interpreted according to the new semantics, an extended syntax is needed in order to store fuzzy membership values within the statements. We give conditions an extended interpretation must meet to be a model of an extended graph. Reasoning in the resulting fuzzy languages can be implemented by current inferencers with minimal adaptations

2007 Can Inconsistent Reasoning Be Complete?

Abstract: As classical reasoning from inconsistent ontologies can't give meaningful answers to queries, it is necessary to either revise the ontology, discarding some axioms in order to restore consistency, or make use of a non-standard notion of logical entailment that allows to give meaningful answers from inconsistent premises. We propose a complete procedure to reason with inconsistent ontologies and show how ontology revision can be obtained from inconsistency reasoning.

2007 Offerta di Servizi Sociosanitari attraverso la Televisione Digitale Terrestre

Abstract: Quando nel 2012 la Televisione Analogica terminerà le trasmissioni ed i Decoders del Digitale Terrestre (DT) saranno nelle case di tutti gli Italiani, gli Enti Pubblici non saranno più giustificati nel fornire informazioni e servizi solo su Internet. Anche le Aziende Sanitarie dovranno contribuire a ridurre questo “digital divide” portando sul DT le più importanti informazioni e cogenti servizi erogati attualmente tramite Internet. La “Multimedia Home Platform” del DT ha però caratteristiche protocollari e strutturali diverse, per cui è importante capire fin da ora come potranno essere trasportati contenuti dall'ambiente PC allo scenario televisivo, in cui la capacità d'interazione è ridotta dai limiti imposti dal telecomando. La presenza del “canale di ritorno” consentirà al cittadino di inviare richieste di servizi all'Azienda e ricevere risposte personali, garantendo quindi la specificità interattiva e la riservatezza

2007 Ontology Revision without Priority to Incoming Information

Abstract: Ontology evolution is the process of modifying an ontology to preserve consistency during changes. Current work on ontology evolution is based on the idea of bringing the AGM belief change theory to work within ontology evolution. However, AGM's principle of priority to incoming information can not be accepted when the new information represents a new evidence about the world, supposed to be a fixed static entity, while its description is only partial and uncertain. In particular, it can not be accepted in a distributed environment, where the information sources are potentially unreliable. We replace the priority to incoming information with the principle of recoverability: any previously held piece of knowledge should belong to the current knowledge space if consistent with it.odifying an ontology to preserve consistency during changes.
