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 [2PbCO₃·Pb(OH)₂] and cerussite (PbCO₃). Depending on the ratio betwe ...

Jackson Pollock’s Number 1A, 1948

A non-invasive study using macro-x-ray fluorescence mapping (MA-XRF) and multivariate curve resolution-alternating least squares (MCR-ALS) analysis

Journal article (2016) - A Martins (author), J Coddington (author), G Van der Snickt (author), B.A. van Driel (author), C. McGlinchey (author), D. Dahlberg (author), K Janssens (author), J. Dik (author)

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 ...

Sound Synthesis Approach for Noise Annoyance Assessment of Rotorcraft Operations

Conference paper (2013) - D Sabbatini (author), K Janssens (author), S. Hartjes (author), H.G. Visser (author), M Gennaretti (author), Giovanni Bernardini (author)

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 ...
