Active infrared thermography is a nondestructive method for evaluating defects in artworks. A conventional excitation radiation heats the sample and the photothermal response is recorded by an infrared (IR) camera. Classical pulsed excitation has shown the feasibility of such a detection system, but the energy deposition for a long period of time can alter(More)
Monitoring the health of ancient artworks requires adequate prudence because of the sensitive nature of these materials. Classical techniques for identifying the development of faults rely on acoustic testing. These techniques, being invasive, may result in causing permanent damage to the material, especially if the material is inspected periodically. Non(More)
According to both the actual energy context and the latest laws meeting EU requirements about energy certification schemes for buildings, carrying out an energy performance diagnosis is mandatory, notably when buying or selling buildings. Indeed, invisible defaults could have a detrimental effect on their insulating qualities. An in-situ estimation of(More)
Although development is a single hierarchical process, scientists tend to study only one level at a time: molecular, cellular, or organismal. The data and theory are available to integrate molecular, cellular, and organismal levels into a series of maps for development of the Drosophila embryo. These maps link the transcriptional cascade with mitotic and(More)
