Arterial stiffness in symptomatic smokers with normal lung function
2017
Chronic obstructive pulmonary disease (COPD) is associated with cardiovascular morbidity and mortality. Arterial stiffness and endothelial dysfunction index are validated surrogate cardiovascular markers and are increased in subjects with COPD. We tested whether increased arterial stiffness and endothelial dysfunction occur in symptomatic smokers with no evidence of bronchial obstruction. Clinical and lung functional assessments were conducted in smoker subjects with chronic respiratory symptoms and in COPD patients. Pulse wave velocity (PWV), aortic augmentation index (AIx) and reactive hyperaemia index (RHI) were measured to estimate the cardiovascular risk. 48 smokers (male n=37, female …
One-year implant survival following lateral window sinus augmentation using plasma rich in growth factors (PRGF) : a retrospective study
2019
Background The aim of this study was to assess one-year implant survival after lateral window sinus augmentation using PRGF combined with various bone grafting materials. Material and Methods This was a retrospective chart review and radiographic analysis of patients that had undergone lateral window sinus augmentation with PRGF and had dental implants placed at least 6 months post augmentation. All implants included were followed up for at least one year after placement. Demographic, sinus and implant related characteristics (residual ridge height, sinus membrane perforation, type of graft material, implant length and width and ISQ at placement) were analyzed. Results A total of 31 patient…
Reverse Engineering, Rapid prototyping and augmented Reality: integrated techniques for new models of fruition of archeological heritage
2013
Reverse engineering (RE) and Rapid Prototyping (RP) have long been used for the representation, interpretation and communication of artistic and archaeological heritage, as well as their museum fruition. An application is given by the construction of models for tactile perception for blind-users: it has been developed a model, in real scale, of a kantharos of the sixth century BC modeled with mixed techniques of rapid prototyping CNC with polymeric resin. Another possible application is the integration of RE and RP techniques with Augmented Reality (AR). It has been made an experiment on the model of the Temple of Castor and Pollux in Agrigento. The physical model, made with additive proces…
Journalism in virtual reality : opportunities and future research challenges
2016
This paper presents a state-of-the-art overview on journalism and its opportunities and challenges in virtual reality. First we take a look at what kind of real-life journalistic experiments there have been made in this field so far, then we analyze the research literature on journalistic VR. The paper proceeds to discuss the emergence of virtual reality and immersive journalism explored in the latest reports in the fields of HCI and VR design. In order to analyse VR-journalism further, early draft of analysis model is being developed based on sample of three VR-productions and four VR-applications. The paper concludes to discuss the results of the analysis and outlines more advanced and in…
Real Virtuality: A Code of Ethical ConductRecommendations for Good Scientific Practice and the Consumers of VR-Technology
2016
The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting that one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go …
Simulation d’un Affichage Tête Haute - Réalité Augmentée pour l’aide visuelle à la conduite automobile
2016
Head-Up Display is the emerging solution for visual aid while driving a car, especially during reduced visibility conditions, such as bad weather or when the road is poorly lighted. The HUD device allows to project virtual information in the central field of view of the driving scene, enabling the driver to keep his attention on the road. The visual perception of the driver is therefore augmented, with a coexistence between the real and virtual world. However, it is necessary to ensure an optimal setting in order to guarantee the good perception of the virtual information, and allow drivers to take appropriate actions at the right moment. This thesis project is dedicated to study three impo…
Empirical Study on Cyber Range Capabilities, Interactions and Learning Features
2021
Emerging technologies and the globalization require constant investment in people and their performance in actual and virtual environments. New technologies such as autonomous systems, machine learning and artificial intelligence (AI) radically re-contextualize the human dimension of the organization. Technological developments are changing the ways people experience the physical and the virtual environments. Strategic changes have revealed new critical vulnerabilities such as social media-based disinformation campaigning with impact on the human aspects at state, societal, organizational and individual levels. Scenarios of gathering information, committing fraud or getting access to critic…
El SandBox, una aplicación de representación espacial de realidad aumentada de interés para el aprendizaje de la geografía
2022
La SandBox est une technologie développée par l’UC Davis qui permet de modéliser des terrains en réalité augmentée. Il s’agit d’un système permettant de sculpter dans le sable un paysage qui va être topographié par l’ordinateur. Une carte d’élévation (2D), composée de courbes et de couleurs, est projetée dans l’espace d’expérimentation (3D). L’opération se fait en direct, ce qui permet une grande interactivité. Les représentations bidimensionnelles (carte 2D) ne permettent pas toujours une bonne perception de l’espace (3D) représenté, cependant cet article souligne comment utiliser la SandBox pour pallier aux difficultés rencontrées lors de la lecture de ces représentations. Il détaille com…
Treating cockroach phobia using a serious game on a mobile phone and augmented reality exposure: A single case study
2011
In vivo exposure has proved its efficacy in the treatment of specific phobias; however, not all patients benefit from it. Communication and information technologies such as Virtual Reality (VR) and Augmented Reality (AR) have improved exposure treatment adherence and acceptance. Serious games (SG) could also be used in order to facilitate exposure treatment. A line of research on SG is emerging which focuses on health issues. We have developed a SG for the treatment of cockroach phobia that uses a mobile phone as the application device. This work examines results of an N = 1 study about whether the use of this mobile game can facilitate treatment of this specific phobia preparing her for th…
Aumentare Palermo. Manifesta 12 studios: scenari, progetti e visioni
2018
From june 16th to November 4th , 2018, Manifesta, the european nomadic art Biennial, held Palermo as host city of its 12th edition. Whithin this larger main framework, over the course of two semesters, four international studios from four celebrated schools of architecture have investigated, reflected and proposed future scenarios for the city of Palermo . The works have been displayed in a collective exhibition at the former mill of the Convent of San Antonino – one of UNIPA’s main locations. The University of Palermo has contributed with the project conceived by PalermoLab, a groupment of six design studios (Proff. M. Carta, A. Badami, R. Lecardane, M. Picone, Z. Tesoriere, F. Schilleci) …
