MOBILE MAPPING FOR CULTURAL HERITAGE: THE SURVEY OF THE COMPLEX OF ST. JOHN OF THE HERMITS IN PALERMO (ITALY)
2023
Abstract. During the 11th and 12th century, the Arab-Norman architectural style characterized the most beautiful and important Cultural Heritage buildings in Sicily, and especially in Palermo (Italy). The relevance of these monuments is highlighted by their inclusion in the UNESCO World Heritage Sites List in 2015. For many years, the University of Palermo has been studying and documenting several Arab-Norman cultural assets, and in particular, the complex of St. John of the Hermits in Palermo (Italy). A first detailed 3D survey of the main structures of this complex was carried out using a terrestrial laser scanner while the 3D survey of the entire complex was made using a Mobile Mapping S…
GEOMATIC TECHNIQUES FOR THE COLONNADE STRUCTURAL ANALYSIS OF THE HISTORICAL “ CHIARAMONTE STERI” BUILDING
2019
The monitoring of building structures has an increasingly important role in the engineering field, above all because they are concerned with the impact that such structures have in the area where they were built. Often, when walking through the old town centres, we realize just how obsolete and dangerous some buildings (even historic-cultural ones) are. The interest of some local governments in this problem has led, in the last few years, to the study and the trying out of measuring and monitoring methods which, quickly and at low cost, allow to define the extent of the deformation and the degrade in an accurate and reliable way. The Courtyard of “Palazzo Steri - Chiaramonte” is composed of…
TECNOLOGIE DI RILIEVO 3D PER LA DOCUMENTAZIONE, L’INTERPRETAZIONE E LA VALORIZZAZIONE DEL PATRIMONIO ARCHEOLOGICO: IL CASO STUDIO DEL PARCO ARCHEOLOG…
2020
In recent decades, the application of geomatics technologies and methodologies to archaeological studies has led to a substantial change in onsite survey techniques and allowed an interdisciplinary approach between archaeology and digital technologies. The employment of these techniques aims to reduce the time of research and documentation, to acquire large amounts of data and to manage, in a more efficiently and quickly way, different datasets. Moreover, these new approaches provide non-invasive, flexible, low-cost methodologies to improve archaeological documentation from a quantitative and qualitative point of view. Nowadays, archaeologists can take advantage of various recording techniq…
Crowd sourcing and low cost strategies of survey for documentation and analysis of museum collections
2019
In these last years, there has been an increasing use of the Structure from Motion (SfM) techniques applied to Cultural Heritage. The accessibility of SfM software can be especially advantageous to users in non-technical fields or to those with limited resources. Thanks to SfM using, everyone can make with a digital camera a 3D model applied to an object of both Cultural Heritage, and physically Environment, and work arts, etc. One very interesting and useful application can be envisioned into museum collection digitalization. In the last years, a social experiment has been conducted involving young generation to live a social museum using their own camera to take pictures and videos. Stude…
Automatic crack detection results using a novel device for survey and analysis of road pavement condition
2019
To accurately schedule maintenance operations, it is crucial to monitor the pavement state and, thus, evaluate the structural and functional indices during its entire service life. In particular, surface conditions (cracks, potholes, patches, rutting, etc.) must be properly checked – especially in terms of detection, identification, and classification of distresses – for avoiding reaching dangerous values for users (overpassing safety thresholds). However, monitoring and survey activities can be so costly (not only in economic terms, but further considering the execution time) to discourage their execution, with evident drawbacks for a proper maintenance management and the related intervent…
On the FON astroplate project accomplishment
2019
The plan for a photographic survey of the northern sky (FON) was proposed at the Golosiiv observatory (Main Astronomical Observatory, NAS of Ukraine, Kyiv, Ukraine) in the late 1970-ies [Pakuliak et al., 2016; Vavilova, 2016; Vavilova et al., 2017]. The last compilation of the final catalog of objects involves 5,700 digitized astroplates of four observatories: MAO NAS of Ukraine (Kyiv, Ukraine) [Andruk et al., 2016], Kitab Astronomical Observatory (Tashkent, Uzbekistan) [Yuldoshev et al., 2017], Gissar Astronomical Observatory (Dushanbe, Tajikistan) [Mullo-Abdolov et al., 2017, 2018], and the observatory in Baldone (Latvia) [Eglitis, 2017]. The consolidated catalog of positions and B-magnit…
Field rules and bias in random surveys with quota samples : an assessment of CIS surveys
2018
Surveys applying quota sampling in their final step are widely used in opinion and market research all over the world. This is also the case in Spain, where the surveys carried out by CIS (a public institution for sociological research supported by the government) have become a point of reference. The rules used by CIS to select individuals within quotas, however, could be improved as they lead to biases in age distributions. Analysing more than 545,000 responses collected in the 220 monthly barometers conducted between 1997 and 2016 by CIS, we compare the empirical distributions of the barometers with the expected distributions from the sample design and/or target populations. Among other …
Self-reported antibiotic stewardship and infection control measures from 57 intensive care units: An international ID-IRI survey
2022
Infection control; Multidrug resistance; Stewardship Control de infección; Resistencia a múltiples fármacos; Administración Control d'infecció; Resistència a múltiples fàrmacs; Administració We explored the self-reported antibiotic stewardship (AS), and infection prevention and control (IPC) activities in intensive care units (ICUs) of different income settings. A cross-sectional study was conducted using an online questionnaire to collect data about IPC and AS measures in participating ICUs. The study participants were Infectious Diseases–International Research Initiative (IDI-IR) members, committed as per their institutional agreement form. We analyzed responses from 57 ICUs in 24 countri…
Preferencias de los y las estudiantes universitarias sobre el empleo desde una perspectiva de género
2015
Se presenta un estudio de encuesta sobre las preferencias que tiene el alumnado universitario al decidirse por un trabajo, lo que creen que les debe aportar y cómo debe ser la empresa en la que desearían trabajar en función de la variable género. Diferentes investigaciones, señalan que las personas desarrollan valores, expectativas y habilidades profesionales diferentes asociadas a la carrera y a la profesión en función del género. El objetivo de este trabajo es analizar los factores que llevan a los y las jóvenes a percibir el trabajo o profesión y determinar si dicha percepción es diferente por ser hombre o mujer. A través de un cuestionario ad hoc compuesto por 52 ítems de escala Likert…
Gaia -ESO Survey: Analysis of pre-main sequence stellar spectra
2015
This paper describes the analysis of UVES and GIRAFFE spectra acquired by the Gaia-ESO Public Spectroscopic Survey in the fields of young clusters whose population includes pre-main sequence (PMS) stars. Both methods that have been extensively used in the past and new ones developed in the contest of the Gaia-ESO survey enterprise are available and used. The internal precision of these quantities is estimated by inter-comparing the results obtained by such different methods, while the accuracy is estimated by comparison with independent external data, like effective temperature and surface gravity derived from angular diameter measurements, on a sample of benchmarks stars. Specific strategi…
