Sensitivity of the C-band SRTM DEM Vertical Accuracy to Terrain Characteristics and Spatial Resolution
2008
This work reports the results of a careful regional analysis of the SRTM DEM (Shuttle Radar Topography Mission – Digital Elevation Model) vertical accuracy as a function of both topography and Land-Use/Land Cover (LULC). Absolute vertical errors appear LULC-dependent, with some values greater than the stated accuracy of the SRTM dataset, mostly over forested areas. The results show that the structure of the errors is well modeled by a cosine power n of the local incidence angle (θloc). SRTM quality is further assessed using slope and topographical similarity indexes. The results show a lower relative accuracy on slope with a R2 = 0.5 and a moderate agreement (Kappa ≈ 0.4) between SRTM- and …

New technologies for promoting physical activity in healthy children and in children with chronic respiratory diseases: A narrative review
2021
Physical activity (PA) is proven to benefit children and adolescents in several ways. New technologies may provide children with stimulating modalities for organizing their leisure time, accessing fitness programs, and obtaining daily goal reminders and peer support. Due to the current COVID-19 pandemic, following WHO recommendations for PA is difficult for many children, especially for those living in urban areas. Therefore, the use of digital tools to support and maintain PA could be useful in healthy children, as well as in those with chronic respiratory diseases (CRDs). This narrative review aims to summarize the most recent evidence about the role of new technologies in promoting PA in…
Implementing a Digital Wellness Application into Use : Challenges and Solutions Among Aged People
2020
The ageing population is a growing priority area for policy makers and healthcare providers worldwide. Life expectancy is improving, but at the same time, insufficient physical activity threatens older age. Thus, an important question arises: how to improve the probability of people living a healthy and active life in older age. One potential solution to support physical activity and healthy aging is digital wellness technologies. However, digital wellness technologies are still typically designed for younger populations, yet a growing need and potential also among aged people is prevalent. Aged people are a user group with distinct needs and challenges. The main purpose of this study was t…
Using Sport and Wellness Technology to Promote Physical Activity: An Intervention Study among Teenagers
2019
Life-long physical activity patterns are established during teenage years. Thus, promoting physical activity for teenagers is important. Sport and wellness technology shows promise for promoting physical activity. Yet, its research with teenage populations is sparse. This intervention study focused on whether using a sport and wellness technology application could affect the physical activity intention of teenagers, its antecedents, and the antecedents’ effects on intention by using the theory of planned behavior combined with the concept of self-efficacy as a theoretical framework. The results showed no statistically significant difference between the intervention and the control group in …
Demographic Differences in the Effectiveness of a Physical Activity Application to Promote Physical Activity: Study Among Aged People
2021
The global population is ageing and simultaneously the life expectancy at older ages is improving. To support healthy and active aging, it is imperative to find solutions to support physical activity (PA) in older age. Digital wellness technologies are a potential solution, but in order for such technologies to be successful, research is needed to gain a better understanding on their use and effectiveness among aged people. To address this need, this study investigated the effectiveness of a physical activity application to promote PA behavior among aged people of different demographics (gender, age, education, marital status). PA levels were measured before taking the application into use …
Effective strategies for promoting physical activity through the use of digital media among school-age children: A systematic review
2021
Digital media are widespread among school-age children, and their incorrect use may lead to an increase in sedentary levels and the consequences associated with it. There are still few studies that have investigated whether physical activity levels could be increased through their use. The aim of this study was to systematically review the scientific literature in order to identify whether digital strategies and technologies are capable of increasing the level of physical activity. A literature search was performed using the following databases: Pubmed, Scopus, and Web of Science. The main outcomes evaluated the increase in physical activity levels, the number of steps, and the reduction of…

La chiesa dei Gesuiti di Noto antica: indagine e ricostruzione digitale
2019
The church of the Jesuit Order in the ancient city of Noto was destroyed, as the rest of the city, by the earthquake that stroke the Oriental part of Sicily in 1693. Thanks to recent researches conducted into the EFIAN Project (Experimental Fruition Ingenious Ancient Noto) it is possible to retrace the complex history of the building, realizing a 3D model of a hypothetical configuration of the complete church as well. The comparison between surveys and archival documents (especially plans preserved at the BnF) revealed also that the church was uncomplete at the date of the earthquake. Moreover, the layout of the ruins doesn’t match with the known drawings of the first half of the XVII centu…
Il Gran Caffè di Giuseppe Damiani Almeyda
2015
Il testo affronta lo studio di un’opera giovanile di Giuseppe Damiani Almeyda (1834-1911), figura di spicco del panorama architettonico in Sicilia tra la seconda metà dell’Ottocento ed i primi del Novecento. Il progetto del Gran Caffè, vincitore di prestigiosi riconoscimenti, anche se realizzato quando Damiani non era ancora trentenne, risulta molto maturo e segna una tappa importante nella formazione dell’architetto. Se ne ritroveranno richiami progettuali nel Politeama, edificio a cui il suo nome è legato, e in una grandiosa opera didattica, la Scuola Italiana di Architettura Civile, che, purtroppo, non è mai stata pubblicata. I disegni originali, a matita, inchiostro ed acquerello su car…
