DIRECT ANALYSIS IN REAL TIME MASS SPECTROMETRY FOR THE NONDESTRUCTIVE INVESTIGATION OF CONSERVATION TREATMENTS OF CULTURAL HERITAGE

Today the long-term conservation of cultural heritage is a big challenge: often the artworks were subjected to unknown interventions, which eventually were found to be harmful.The noninvasive investigation of the conservation treatments to which they were subjected to is a crucial step in order to undertake the best conservation strategies.We descr

This paper explores how inertial Pedestrian Dead-Reckoning (PDR) location systems can be improved with the use of a light sensor to measure the illumination gradients created when a Portable Vaporizers person walks under ceiling-mounted unmodified indoor lights.The process of updating the inertial PDR estimates with the information provided by ligh
