Social Psychology of Persuasion Applied to Human Agent Interaction
2008
This paper discusses and evaluates the application of a social psychologically enriched, user-centered approach to agent architecture design. The major aim is to facilitate human–agent interaction (HAI) by making agents not only algorithmically more intelligent but also socially more skillful in communicating with the user. A decision-making model and communicative argumentation strategies have been incorporated into the agent architecture. In the presented content resource management experiments, enhancement of human task performance is demonstrated for users that are supported by a persuasive agent. This superior performance seems to be rooted in a more trusting collaborative relationship…
Proposta di un framework per la progettazione didattica a scuola
2021
Il presente lavoro di ricerca ha inteso verificare la validità di una struttura predefinita per la stesura di un progetto didattico, precisamente quella fornita agli studenti durante il tirocinio. La progettazione è un fattore chiave nella mediazione tra insegnamento e apprendimento a scuola; le sue fasi investono sia il piano gestionale sia quello delle finalità generali, fino a quello dell’agire in classe e della valutazione. Nel tirocinio 684 futuri insegnanti di scuola dell’infanzia e primaria, frequentanti il corso di laurea in Scienze della Formazione Primaria di Palermo negli anni 2016-2020, hanno utilizzato un frame di progettazione e valutazione didattica; esso è stato costruito te…
Effect of Sex, Body Mass Index and Physical Activity Level on Peak Oxygen Uptake Among 14–19 Years Old Adolescents
2020
The aim was to describe longitudinal trends in peak oxygen uptake (VO2peak) among 14- to 19-year-old adolescents in Norway, and to examine effects of sex, body mass index (BMI), and physical activity (PA) level on VO2peak during adolescence. Of 124 invited students from two lower secondary schools in Norway, 116 eighth-grade students (61 boys and 55 girls; 14 years old at baseline) volunteered to participate. The study has a longitudinal design with 6 yearly repeated measures of body height and mass, VO2peak and PA level. VO2peak allometrically scaled to body mass raised to the power of 0.67 was measured using a walking or running incremental test on a treadmill, whereas PA level was self-r…
A fuzzy parameter to characterize the uncertainty in the plant layout design
2015
The present work aims at proposing a methodology able to return a single parameter that synthesizes the aspects characterizing the layout design problem that the analyst translates into requests of closeness and distance among departments. In order to consider the uncertainty of the problem, closeness and distance requests are expressed by means of fuzzy numbers and a weight fuzzy function modules the importance of the aspects by allowing the analyst to express his/her priorities on the basis of the specific decisional context. The weight function is characterized by the presence of a threshold value that makes the method non compensative. The hypothesis herein assumed is that, when the dis…
Active lighting applied to three-dimensional reconstruction of specular metallic surfaces by polarization imaging
2006
International audience; In the field of industrial vision, the three-dimensional inspection of highly reflective metallic objects is still a delicate task. We deal with a new automated three-dimensional inspection system based on polarization analysis. We first present an extension of the shape-from-polarization method for dielectric surfaces to metallic surfaces. Then, we describe what we believe to be a new way of solving the ambiguity concerning the normal orientation with an active lighting system. Finally, applications to shape-defect detection are discussed, and the efficiency of the system to discriminate defects on specular metallic objects made by stamping and polishing is presente…
Design per il settore pubblico
2021
Il settore pubblico è uno dei nuovi terreni di sperimentazione per l’attività dei designer che si confrontano con le sfide della realtà contemporanea. Alla luce dei cambiamenti sociali, culturali, poli- tici ed economici in atto, le istituzioni governative hanno iniziato a mostrare il proprio interesse verso una serie di approcci ispirati al design da applicare nella definizione di strategie innovative in grado di favorire l’implementazione di politiche adeguate ai nuovi bisogni espressi dalla società. Le esperienze progettuali raccolte e descritte in questo paper testimoniano il successo dei risultati ottenuti dalla collaborazione tra designer e pubbliche amministra- zioni, definendo così …

All'interno di questo scenario Il design può diventare un buon intermedlano per und progettazione e produzione che usa strategie eco-efficienti.
Improvements in Rational Design Strategies of Inulin Derivative Polycation for siRNA Delivery.
2016
The advances of short interfering RNA (siRNA)-mediated therapy provide a powerful option for the treatment of many diseases, including cancer, by silencing the expression of targeted genes involved in the progression of the pathology. On this regard, a new pH-responsive polycation derived from inulin, Inulin-g-imidazole-g-diethylenetriamine (INU-IMI-DETA), was designed and employed to produce INU-IMI-DETA/siRNA "Inulin COmplex Nanoaggregates" (ICONs). The experimental results showed that INU-IMI-DETA exhibited strong cationic characteristics and high solubility in the pH range 3-5 and self-aggregation triggered by pH increase and physiological salt concentration. INU-IMI-DETA showed as well…
Enhanced chain dynamics in loop-sorting-systems by means of layout optimization and a kinematic model of the polygon action
2012
Published version of an article in the journal: Structural and Multidisciplinary Optimization. Also available from the publisher at: http://dx.doi.org/10.1007/s00158-011-0743-7 Poor dynamics owing to polygon action is a known concern in mechanical applications of closed articulated chains. In this paper a kinematic model of the polygon action in large chains of loop-sorting-systems is proposed. Through optimization techniques the chain dynamics is improved by minimizing the polygon action using a parametric model of the track layout as design variables. Three formulations of the kinematic polygon action are tested on an average sized planer tracks layout to find a superior model. Verificati…
An algorithm based on the PPC (Polynomial Parametric Curve) for designing horizontal highway alignments
2015
Criteria for geometric design of highway alignments have been studied in various researches so far, providing new methods, as alternative to traditional approaches. They can be useful for obtaining better solutions, characterized by high performances in terms of motion safety and comfort. In particular, continuous curvature alignments, based on polynomial functions, are highly consistent solutions with users' driving behaviour and vehicle trajectories. Moreover, alignment geometry optimization allows engineers to minimize dynamic effects on drivers with considerable advantages in terms of comfort and safety. This paper carries on the research of a previous study, in which a polynomial param…
