Architettura e Design

E-learning, knowledge sharing, creativity design and collaborative innovation are all concepts that are key elements of this case study. There is a particular focus here on the question of what role design should play in innovation. Other key topics include the role of e-learning and of long life learning. Such roles are not always easy to explain, since they differ from case to case, but Design in Italy is – and will increasingly become – a definite value and a competitive tool. Design can and must be a fundamental part of every single company's production, communication and distribution strategy. Every e-learning platform launched by Università Telematica San Raffaele Roma's " Design for Business & Business for Design " is intended to demonstrate that design is neither a sole interest nor an exclusive prerogative of large companies or those operating in sectors that have traditionally been design oriented. In fact, design-driven education and innovation is a basic lever for competitiveness and internationalization that is available in every sector. Creating an e-learning platform is an important way of building a designing and community identity; a significant chance to meet and a landmark not only for professionals, but also for creative people working outside established enterprises.

From its first introduction in this same conference, the original prototype of the Semantic Bookmarking tool Semantic Turkey has undergone a deep and extensive revision process, breaking the boundaries of its original intents and going more and more towards an extensible platform for Knowledge Management and Acquisition based on Semantic Web technologies. Following its recent official release, we discuss here the main innovations of this system, its potential applications and future plans for its improvement

In this work we describe Semantic Turkey, a Semantic Extension for the popular web browser Mozilla Firefox. Semantic Turkey can be used to keep track of relevant information from visited web sites and organize collected content according to a personally defined ontology. In this sense, Semantic Turkey can be seen both as an advanced semantic bookmarking system as well as an ontology editing assistant, which allows domain experts and ontology developers to build ontologies starting from the very raw source of information which they find on the web. The open architecture of Semantic Turkey and the specific threelayered approach of its design also allows for scaling the basic personal desktop application embodied by this tool up to a distributed framework for collaborative semantic annotation and ontology editing. This paper describes the architecture and the functionalities of the Semantic Turkey extension for Firefox, and describe possible evolutions for future improvement of the tool.

This paper describes the experience of introducing a service for semantic bookmarking and search in the Earth Observation (EO) domain. To perform the work reported such a service has been integrated and customized in the framework of the DILIGENT project which concluded in 2007. The service proposed is a web browser ontology based extension: at the application layer the interaction between DILIGENT end-users and this service takes place from within the DILIGENT web portal. The service described allows end users to capture and annotate on-demand the information stored in the DILIGENT infrastructure and to organize it according to the user's representation of the specific ontological domain. The effort spent meets today end users' requirements in the EO application domain, applying an innovative solution to make specific actors keep track of the information of interest in a personalized and easy way. End users are able to store, access and play only with the information of interest and under their own (ontological) perspective.

In this paper we present a novel approach to browsing RDF Data on the web . Our approach is based on automatic generation of GUIs for RDF data. Our objective is to provide a methodology able to apply the existing pattern chosen from users of representation at an RDF repository and generate automatically a GUI that show this data to the users.

In this paper we present the Semantic Turkey Ontology Learner (ST-OL), an incremental ontology learning system, that follows two main ideas: (1) putting final users in the learning loop; (2) using a probabilistic ontology learning model that exploits transitive relations for inducing better extraction models.

In this work we present STIA a tool for text annotation in the jurisprudence domain. The tool offers an easy interface to experts (lawyers, administrative, researchers,…) for annotating qualified relationships between parts of different laws. Successively, the resulting conceptual annotations feed a complex process to retrieve specific relationships between texts (groups of sentences inside a section) of two laws for new application tasks…

The Semantic Web dream of a real world-wide graph of interconnected resources isslowly but steadilybecoming a concrete reality. Still, the whole range of models and technologies which will change forever the way we interact with the web, seems to be missing from every-day technologies available on our personal computers. Ontologies, annotation facilities and semantic querying could (and should) bring new life to Personal Information Management, supporting users in contrasting the ever-growing information overload they are facing in these years, overwhelmed by plethora of communication channels and media. In this paper we present our attempt in bringing the Semantic Web Knowledge Management paradigm at the availability of diverse personal desktop tools (Web Browser, Mail clients, Agenda etc…), by evolving Web Browser Semantic extension Semantic Turkey to an extensible framework providing RDF data access at different levels: java access through OSGi extensions, HTTP access or dedicated JavaScript API for the whole range of tools from the open source suite of Mozilla applications

This paper reports the experience of the development and the evaluation of a set of pre-competitive tools to support legal professionals in exploring a complex corpus of norms and documents in the legal domain. The research addresses two complementary goals: using ICT to support the simplification of the corpus of norms and using ICT to facilitate search and retrieval of information in large archives in the legal domain. The contribution of this work is in the development of tools beyond state of the art for the e-discovery of relationships between sections of norms or other legal documents. To reach the best results in terms of effectiveness, the tools combine statistical and the semantic approaches. The effectiveness of the statistical tool has been measured in terms of precision, through an assessment procedure that involved some experts of the legal domain.

Abstract The Semantic Search research field aims to query metadata and to identify relevant subgraphs. While in traditional search engines queries are composed by lists of keywords connected through boolean operators, Semantic Search instead, requires the submission of semantic queries that are structured as a graph of concepts, entities and relations. Submission of this graph is however not trivial as while a list of keywords of interest can be provided by any user, the formulation of semantic queries is not easy as well.

Abstract The Semantic Web is facing the important challenge to maintain its promise of a real world-wide graph of interconnected resources. Unfortunately, while URIs almost guarantee a direct reference to entities, the relation between the two is not bijective. Many different URI references to same concepts and entities can arise when--in such a heterogeneous setting as the WWW--people independently build new ontologies, or populate shared ones with new arbitrarily identified individuals.

Polymers offer many advantages (price, corrosion resistance, etc.) as construction materials for efficient heat exchangers. A disadvantage is a lacking permeation barrier in regard to heat transfer media. The transient swelling properties of the thermoplastic polymers polyetheretherketone (PEEK), polypropylene (PP) and polysulfone (PSU) are studied in different modifications and various solvents. The solubility parameter theory can be applied to the observed equilibrium swelling ratios, which makes it promising for future process specific material pre-selection. The amount of increasing hydrophobic surface character, even for small equilibrium swelling ratios, was found to be related to the increase in polar part of surface free energy. This wetting enhancement can be compared to the amount achieved with common treatment technologies (plasma, corona) and is of interest in heat exchanger processes.

UPM bio-fibrils are nano-structured cellulose fibers (nano-fibrils) produced by UPM Kymmene-Corporation, a Finnish company. This paper reports a preliminary study about nano-fibrils to determine their possible use for restoration of historical mortars and plasters. The aim of this study is to investigate the behavior of some mixtures added with nano-fibrils in their properties for conservative purposes. These mixtures reproduce the composition of historical mortars and plasters, made of natural hydraulic lime (NHL 3.5) and river sand. After 28 days of hardening, the properties of specimens with nano-fibrils were compared with untreated one to understand how nano-fibrils interact with inorganic matrix. The fibrils influenced the properties in different ways. For example, mechanical tests showed a decrease of flexural and compressive strength as the percentage of nano-fibrils increased.

Knowledge of the flora, as part of the environment of archaeological sites, and its management are fundamental aspects for their safeguard and use. The case study of the ruins of the roman villa of Durrueli in Sicily (1st century AD),is representative of all the issues related to the presence of vegetation in a coastal environment. The site is a rare case of " maritime villa " in the south coast of Sicily, and is characterized by the presence of precious sectilia marble pavements and polychrome mosaics depicting sea creatures and myths. The development of the flora in the archaeological site of Durrueli requires a particular care, due to the deep alterations of the stone and the mosaics arising from the presence of natural vegetation in the structuresexposed to weathering processes, which are particularly strong in an environment so close to the sea.The vegetation developing in this area is constituted by different organisms, going from the crittogamae, such asalgae, lichensand pteridophitae, to the fanerogamae, represented by annual or perennial weeds, as well as shrubs and fully developed trees. In order to carry on their biological cycle these organisms have to take the elements for their growth, both from the atmosphere, as from the substratum in which they grow, causing various deterioration processes to the ruins. In this paper, starting from theissues of the Durrueli study case, a general approach to flora analysis is proposed, taking into account different ecological, management and conservation parameters. Introduzione La conoscenza della flora fornisce una preziosa occasione per conoscere, valorizzare ed esaltare le caratteristiche e le peculiarità dei siti archeologici, in stretta relazione al patrimonio ambientale in cui sono inseriti, e costituisce altresì un apporto di primaria importanza a causa delle profonde alterazioni che gli organismi vegetali possono determinare sulle rovine e sulle città antiche. Il valore del patrimonio culturale da difendere, infatti, non consente errori di intervento e tuttavia, non giustifica l'eradicazione totale degli organismi vegetali e la creazione di spazi aridi e privi di emergenze ambientali, che migliorino la leggibilità ed accrescano il fascino VI th Conference " Diagnosis, Conservation and Valorization of Cultural Heritage " 10/11 December 2015 dei resti archeologici. Gli equilibri della flora all'interno delle aree archeologiche, vanno infatti esaminati, compresi, guidati e non distrutti, nell'ottica di uno sviluppo della vegetazione equilibrato ed in armonia con gli obiettivi della tutela, conservazione e fruizione delle risorse culturali ed archeologiche esistenti.

The research compare  the state of conservation of ruins in the archaeological sites of Morgantina and Solunto, which offer quite different environmental and physical characteristics: the settlement in Solunto occurred with terracing on the Catalfano Mountain, only a few hundreds meters by the sea; whereas in Morgantina the settlement expanded on flat or slightly sloping grounds, among the inner hills of Sicily.

Thirty-four plug positive females were randomly divided into two groups. Animals were given by gavage 0 and 6 mg PFOS/kg/day on gestation days (GD) 12-18. One-half of the animals in each group was subjected to restraint stress (30 min/session, three sessions per day) during the same period. Neither restraint nor PFOS exposure significantly modified maternal food or water consumption. Pups of dams exposed to 6 mg/kg of PFOS showed a reduced body weight on postnatal days 4 and 8. Moreover, PFOS exposure induced some delay in developmental landmarks and neuromotor maturation. Maternal restraint stress reduced activity in an open-field when combined with 6 mg PFOS/kg/day. In addition, in males prenatal restraint stress impaired motor coordination in a rotarod. The current results indicate that concurrent exposure to PFOS and restraint stress during pregnancy induces opposite effects on developmental parameters in the pups. These effects consist in a general delayed maturation trend induced by PFOS exposure, and a general accelerated maturation pattern induced by prenatal stress. Interactive effects between PFOS and maternal stress were observed in young adult mice. These effects consisted mainly in a diminished activity in an openfield test.
