Technologies for Conservation and Restoration of Cultural Heritage

Introduction of atmospheric physics applied to microclimate analysis and conservation. Atmospheric composition, atmospheric pressure and vertical profile. The Fundamental forces: the pressure gradient force, the gravitational force, the viscous force. Noninertial reference frame and the apparent forces. Scale analysis. The basic conservations laws in the Lagrangian and Eulerina frames: conservation of mass, momentum and energy. Geostrophic flow, the effect of the friction. Generality on atmospheric turbulence. Measuring wind and indoor motions: hot wire anemometry and sonic anemometer. Air temperature, indoor temperature. The key moisture variables (mixing ratio of dry air and water vapor, absolute humidity, specific humidity, relative humidity). Wet bulb temperature and dew point temperature. The psichrometric chart. Air-surface intercations and environmental diagnostics. Condensation of liquid water on the object surface. Time-of-Wetness. Micropore condesation. Kelvin equation. The solar spectrum, attenuation of light in the atmosphere, daily and seasonal cycles of solar radiation on a surface, radiation emitted by Earth and its atmosphere. Radiative balance and energy balance at surface. Characterizing indoor conditions with descriptive statistical analysis of microclimate data on the basis of European Standards

Recommended

Two mid-term written exams. 1° on the first part of the program contents 2° on the second part of the program contents. Otherwise a written exam on the whole program. The final score can be improved with oral exam

Lectures, Active learning discussion sessions, active and passive problem solving classes, home work. The formative assessment is performed via interaction between teacher and students during lectures and exercises. Students are involved in questioning, in discussion and in proposing strategies to solve exercises, by means of open oral questions to the entire class.
