Radar detection of pedestrian-induced vibrations on Michelangelo’s David

This paper summarizes the results of a two-day dynamic monitoring of Michelangelo's David subject to environmental loads (city traffic and pedestrian loading induced by tourists visiting the Accademia Gallery). The monitoring was carried out by a no-contact technique using an interferometric radar, whose effectiveness in measuring the resonant frequencies of structures and historic monuments has proved over the last years through numerous monitoring activities. Owing to the dynamic behavior of the measurement system (radar and tripod), an accelerometer has been installed on the radar head to filter out the movement component of the measuring instrument from the measurement of the David's displacement. Measurements were carried out in the presence and absence of visitors, to assess their influence on the dynamic behavior of the statue. A numerical model of the statue was employed to evaluate the experimental results

Key pedagogical and technological factors for effective blended learning design

This is a report by the expert pools of the EMPOWER programme established by EADTU to cover the latest trends and developments in new modes of teaching. New modes of teaching and learning create new opportunities for enhancing the quality of the learning experience in on campus programmes, reaching out to new target groups off campus and offering freely accessible courses nationally or worldwide through the internet. They enhance the quality, visibility and reputation of the institution.Co-funded by the Erasmus+ Programme of the European Unioninfo:eu-repo/semantics/publishedVersio

Global carbon accounting tool (GCAT) for manufacturing supply chains:the world model

This research presents a global carbon accounting tool (GCAT) developed by the Sustainable Systems & Solutions Lab (S3-Lab) at Istanbul Sehir University, Turkey. This tool is able to capture the regional and global carbon footprints of manufacturing supply chains for world's 40 major economies. The GCAT will enable users to conduct carbon footprint analysis for the specific industry of selected country in 5 steps (http://s3-lab.sehir.edu.tr/gcat.html). The European food and drink industry will be chosen as a case study to conduct supply chain-based carbon footprint analyses including production versus consumption based analysis, sector breakdown for supply chain components, scope-based analysis and impact-by-country analysis for supply chain carbon emissions

PS of the displacement measured by the radar (red) and the accelerometer (blue), and the result of the correction (green).

<p>The peaks at 5.94 Hz and 11.88 Hz are attenuated, while the ones at 5.12 Hz, 11.05 Hz and 14.24 Hz disappear after the correction of the signal.</p
