Until the 19th century, lead white was the most important white pigment used in oil paintings. Lead white is typically composed of two crystalline lead carbonates: hydrocerussite [2PbCO<sub>3</sub>·Pb(OH)<sub>2</sub>] and cerussite (PbCO<sub>3</sub>). Depending on the ratio between hydrocerussite and cerussite, lead white can be classified...

Jackson Pollock’s Number 1A, 1948 painting was investigated using in situ scanning macro-x-ray fluorescence mapping (MA-XRF) to help characterize the artist’s materials and his creative process. A multivariate curve resolution-alternating least squares (MCR-ALS) approach was used to examine the hyperspectral data and obtain distribution maps and...

The painting An Old Man in Military Costume in the J. Paul Getty Museum, by Rembrandt Harmensz van Rijn, was studied using two complementary, element-specific imaging techniques—neutron activation autoradiography (NAAR) and macro-X-ray fluorescence (MA-XRF) mapping—to reveal the second, hidden painting. NAAR provided a strong image of the face...

The development of advanced methods for non-destructive selective imaging of painted works of art at the macroscopic level based on radiation in the X-ray and infrared range of the electromagnetic spectrum are concisely reviewed. Such methods allow to either record depth-selective, element-selective or species-selective images of entire...

This paper presents a sound synthesis approach that allows investigating the noise annoyance of rotorcraft in relation to the source components and flight path. The sound synthesis is based on a source-transfer-receiver model, describing the noise emission and directivity of the sources and their propagation towards the receiver point on the...

Over the past several decades the oeuvre of Rembrandt has been the subject of extensive art historical and scientific investigations. One of the most striking features to emerge is his frequent re-use of canvases and panels. The painting An Old Man in Military Costume (78.PB.246), in the collection of the J. Paul Getty Museum, is an example of...
