(Elsevier, 2022)
Acceso abierto
A manually classified dataset of images obtained by four static cameras located around a construction site is presented. Eight object classes, typically found in a construction environment, were considered. The dataset ...
High pressure effect in the near-infrared emission of Nd3+-doped alkali silicate glasses
(Taylor & Francis, 2022)
Acceso restringido
The effect of high pressure (7.7 GPa) densification on the absorption and near-infrared emission of Nd-doped lithium, sodium and potassium disilicate glasses was investigated. Judd-Ofelt parameters O¿ (¿ = 2, 4 and 6) were ...
Solutions and limitations of the geomatic survey of an archaeological site in hard to access areas with a latest generation smartphone: the example of the Intihuatana stone in Machu Picchu (Peru)
(International Measurement Confederation, 2022)
Acceso abierto
Archaeological remains need to be geometrically surveyed and set in absolute reference systems in order to allow a "virtual visit" and to create "digital twins" useful in case of deterioration for proper restoration. Some ...
