Students' Understanding of the Special Theory of Relativity and Design for a Guided Visit to a Science Museum
2009
International audience; This paper describes the design of teaching materials that are used as learning tools in school visits to a science museum. An exhibition on the A century of the Special Theory of Relativity, in the Kutxaespacio Science Museum, in San Sebastian (Spain), was used to design a visit for first year engineering students at the university and assess the learning which was achieved. The first part of the paper presents the teaching sequence which was designed to build a bridge between formal teaching and the exhibition visit. The second part analyses the potential of the exhibition and the aforementioned teaching sequence to influence the students' knowledge of three aspect…
Action Recognition based on Hierarchical Self-Organizing Maps
2014
We propose a hierarchical neural architecture able to recognise observed human actions. Each layer in the architecture represents increasingly complex human activity features. The first layer consists of a SOM which performs dimensionality reduction and clustering of the feature space. It represents the dynamics of the stream of posture frames in action sequences as activity trajectories over time. The second layer in the hierarchy consists of another SOM which clusters the activity trajectories of the first-layer SOM and thus it learns to represent action prototypes independent of how long the activity trajectories last. The third layer of the hierarchy consists of a neural network that le…
Hierarchies of Self-Organizing Maps for action recognition
2016
We propose a hierarchical neural architecture able to recognise observed human actions. Each layer in the architecture represents increasingly complex human activity features. The first layer consists of a SOM which performs dimensionality reduction and clustering of the feature space. It represents the dynamics of the stream of posture frames in action sequences as activity trajectories over time. The second layer in the hierarchy consists of another SOM which clusters the activity trajectories of the first-layer SOM and learns to represent action prototypes. The third - and last - layer of the hierarchy consists of a neural network that learns to label action prototypes of the second-laye…
Activity Monitoring Made Easier by Smart 360-degree Cameras
2023
This paper proposes the use of smart 360-degree cameras for activity monitoring. By exploiting the geometric properties of these cameras and adopting off-the-shelf tracking algorithms adapted to equirectangular images, this paper shows how simple it becomes deploying a camera network, and detecting the presence of pedestrians in predefined regions of interest with minimal information on the camera, namely its height. The paper further shows that smart 360-degree cameras can enhance motion understanding in the environment and proposes a simple method to estimate the heatmap of the scene to highlight regions where pedestrians are more often present. Quantitative and qualitative results demons…

Improving Assessment of Students through Semantic Space Construction
2009
Assessment is one of the hardest tasks an Intelligent Tutoring System has to perform. It involves different and sometimes uncorrelated sub-tasks: building a student model to define her needs, defining tools and procedures to perform tests, understanding students' replies to system prompts, defining suitable procedures to evaluate the correctness of students' replies, and strategies to improve students' abilities after the assessment session.In this work we present an improvement of our system, TutorJ, with particular attention to the assessment phase. Many tutoring systems offer only a limited set of assessment options like multiple-choice questions,fill-in-the-blanks tests or other types …
Text localization from photos
2009
In this paper a new text extraction algorithm is proposed. In real scenes the text is usually overlapped or is part of the background. To identify the text regions, in complex conditions, a method exploiting a “multi-resolution feature based method” for extracting text with undefined dimension has been developed. Once identified, the multi-resolution information are merged and skimmed through a set of Support Vector Machines (SVM). The tests and the comparisons with other techniques, performed on heterogeneous images, have shown the effectiveness of the proposed.
La decadenza nel diritto del lavoro tra vicende traslative e fattispecie interpositorie
2020
L’art. 32 della legge n. 183/2010 ha sollevato molteplici questioni applicative legate alla sua infelice formulazione. Il saggio analizza il controverso perimetro applicativo del comma 4, lett. c) e d), inerenti rispettivamente la cessione del contratto di lavoro avvenuta ai sensi dell’art. 2112 c.c. e i casi in cui si chieda la costituzione o l’accertamento di un rapporto di lavoro in capo a un soggetto diverso dal titolare del contratto. L’Autore fornisce le coordinate per una corretta interpretazione, opportunamente restrittiva, delle previsioni decadenziali alla luce del dato letterale e del diritto dell’Unione europea.
DOWN SYNDROME AND REFERENTIAL COMMUNICATION: UNDERSTANDING AND PRODUCTION
2011
Children with Down Syndrome (DS) have a delay that affects the global motor development, cognitive, communicative and linguistic. From the literature shows that these subjects follow the same general line of language acquisition of children with typical development, although their language remains behind their non-verbal cognitive abilities and then proceed with a slower. In our study we have set ourselves the objective to investigate some critical dimensions of the communicative function in particular, referential communication, which means the subject's ability to produce messages "referentially oriented”, or messages that allow the listener to recognize the immediacy of contact with the …
Tra mafia, politica e “discorsi di legalità”
2015
Starting from a synthetic review of the studies about the importance of symbolic dimension for the construction of Cosa Nostra’s power (from the area of knowledge to the one of identity, from rituals to myths and apologetics), the paper analyses the ambiguity of the talk-interactions between “men of honour” during the development of conversational grounding for their inter-subjectivity (in Schegloff‘s words). According to the rules, spoken exchanges between Cosa Nostra’s members should be governed by the twofold restriction of the law of silence toward the world outside and the obligation of speaking the truth inside the organization. But in real life, things are different. Mafia’s language…
