Topic: Image processing and satellite imagery analysis using fractional and variational calculation. This research unit covers modelling methods for image processing techniques based on variational and fractional approaches, which can be used in applied physics and in environmental studies, where any human interaction exists with the environment. In particular, the research unit is investigating, through the image processing of satellite imagery, the impact of ancient human activities on their local areas to create a built environment. The image processing used in this investigation was developed during some previous researches on the liquid crystal polarized light microscopy.

Topic: Thermal physics for energy and environmental applications. This research unit is studying the thermal behaviour of some thermal models in periodic regimes. The aim is to simulate the behaviour of small environments at the outermost part of our planet, subjected to the periodic solar radiation. Lumped elements or volumes are used to describe spatially distributed physical systems, through a topology consisting of discrete entities. Energy storage systems are also considered. - AC Sparavigna, Measuring the Thermal Diffusivity in a Student Laboratory Engineering, 4(5) 266-271, 2012; Sparavigna A.C., S. Giurdanella, M.
