Extracting Structured Knowledge From Sensor Data for Hybrid Simulation
2014
Obtaining continuous and detailed monitoring of indoor environments has today become viable, also thanks to the widespread availability of effective and flexible sensing technology; this paves the way for the design of practical Ambient Intelligence systems, and for their actual deployment in real-life contexts, which require advanced functionalities, such as for instance the automatic discovery of the activities carried on by users. Novel issues arise in this context; on one hand, it is important to reliably model the phenomena under observation even though, to this end, it is often necessary to craft a carefully designed prototype in order to test and fine-tune the theoretical models.
A Neuro-Genetic Approach to Real-Time Visual Grasp Synthesis
2007
Grasping is an essential prerequisite for an agent, either human or robotic, to manipulate various kinds of objects present in the world. It is a fact that we would like robots to have the same skills as we do. However, despite the construction of human-hand-like robotic effectors, much work is still to be done in order to give robots the capability to grasp and manipulate objects. The goal of this work is to automatically perform grasp synthesis of unknown planar objects. In other words, we must compute points on the object's boundary to be reached by the robotic fingers such that the resulting grasp, among infinite possibilities, optimizes some given criteria. The space of possible config…
A Study on Classification Methods Applied to Sentiment Analysis
2013
Sentiment analysis is a new area of research in data mining that concerns the detection of opinions and/or sentiments in texts. This work focuses on the application and the comparison of three classification techniques over a text corpus composed of reviews of commercial products in order to detect opinions about them. The chosen domain is about "perfumes", and user opinions composing the corpus are written in Italian language. The proposed approach is completely data-driven: a Term Frequency / Inverse Document Frequency (TFIDF) terms selection procedure has been applied in order to make computation more efficient, to improve the classification results and to manage some issues related to t…
IL CONSENSO INFORMATO NEI PROTOCOLLI CARDIOLOGICI PER IL GIUDIZIO DI IDONEITÀ ALLA ATTIVITÀ SPORTIVA
2008
Il consenso informato nelle attività sportive trova esplicita previsione agli articoli 71 e 72 del Codice di Deontologia Medica. L’articolo 71 prescrive una adeguata informazione al soggetto sugli eventuali rischi che la specifica attività sportiva può comportare. In base a questa indicazione il problema del consenso informato può presentarsi in "senso proprio" quando si eseguono accertamenti, non invasivi o invasivi, per la valutazione dell’idoneità alle attività sportive che possono comportare dei rischi di cui l’interessato deve essere informato e in "in senso ampio" quando l’esperto, scoperta una patologia, ritiene che questa sia compatibile con l’esercizio fisico, anche se in forme e c…
IL RUOLO DELLA CARDIOLOGIA NELLA VALUTAZIONE DELL'ATTIVITA' SPORTIVA
2013
Un allenamento regolare di grado moderato, e di tipo prevalentemente aerobico ha effetti positivi sul benessere generale ed in particolare sulla performance cardiovascolare, apportando un contributo significativo nella prevenzione primaria delle cardiopatie, in quanto elemento essenziale del trattamento di malattie metaboliche quali obesità, diabete mellito, dislipidemia, o dell’aterosclerosi, condizioni riconosciute come fattori di rischio di eventi cardiovascolari. L’esercizio moderato è inoltre essenziale nella prevenzione secondaria e nella fase riabilitativa della cardiopatia ischemica o dell’insufficienza cardiaca. Gli effetti benefici non sono però così chiari quando l’attività fisic…

European fitness landscape for children and adolescents: updated reference values, fitness maps and country rankings based on nearly 8 million test r…
2023
Objectives (1) To develop reference values for health-related fitness in European children and adolescents aged 6–18 years that are the foundation for the web-based, open-access and multilanguage fitness platform (FitBack); (2) to provide comparisons across European countries. Methods This study builds on a previous large fitness reference study in European youth by (1) widening the age demographic, (2) identifying the most recent and representative country-level data and (3) including national data from existing fitness surveillance and monitoring systems. We used the Assessing Levels of PHysical Activity and fitness at population level (ALPHA) test battery as it comprises tests with the h…
Physiological response on 1 RM bench press performance
2012
A number of methods for determining upper body maximal strength are present. The 1-RM is defined as the maximum amount of resistance that can be performed for only 1 repetition and it has been shown to be reliable in various populations. Further, setting an intensity of resistance training based on a percentage of the 1-RM has been found to be effective for improving outcomes such as muscle strength, muscle power, and muscle hypertrophy. Little is known about the metabolic cost of 1RM evaluation and which is the optimal recovery time between sessions. We analyzed the physiological response during a standardized protocol of 1RM-Bench Press Test (1RM-BP). Fourteen healthy subjects (25,6±7,4 y…
A web-based surveillance system on adolescents’ lifestyles and obesity prevention: ASSO-FTB preliminary findings. The ASSO Project
2012
In a context where obesity represents a cause of concern in childhood and where there is a lack of standardized data collection systems, ASSO Project (Adolescents and Surveillance System for Obesity prevention), financed by the Italian Ministry of Health, aims to develop a surveillance system structured on adolescents lifestyles. It is a prospective study with online data collection, simultaneous descriptive data analysis and real time report. The ASSO-Toolkit is made of questionnaires, forms and a fitness test battery: ASSO-PIQ (Personal Information Questionnaire);ASSO-PASAQ (Physical Activity, Smoke, Alcohol, Questionnaire); ASSO- FHQ (Food Habits Questionnaire); ASSO-FFQ (Food Frequency …
EFFETTI DELLA TERAPIA MULTISISTEMICA IN ACQUA SULLE ABILITA’ GROSSOMOTORIE E COGNITIVE IN SOGGETTI CON DISTURBO DELLO SPETTRO AUTISTICO
2015
Lo scopo del presente studio è stato quello di studiare gli effetti della “terapia multisistemica in acqua” (TMA) sulle abilità grossomotorie e cognitive in bambini con disturbo dello spettro autistico. Le attività hanno coinvolto sei soggetti e si sono svolte attraverso la “pianificazione” di un intervento individualizzato e interpersonale volto a ridurre i sintomi e migliorare le capacità comunicative e relazionali del bambino avvalendosi degli ambienti strutturati delle piscine pubbliche. Dopo l’intervento terapeutico, i soggetti hanno mostrato un miglioramento del quoziente di sviluppo grosso-motorio e una modificazione degli schemi cognitivi, comportamentali, comunicativi ed emotivi. I…
