Network Models in Neuroimaging : A Survey of Multimodal Applications

Mancini M., Cercignani M.

Fundamenta Informaticae

2018

Vol. 163, nr 1

63--91

Mapping the brain structure and function is one of the hardest problems in science. Different image modalities, in particular the ones based on magnetic resonance imaging (MRI) can shed more light on how it is organised and how its functions unfold, but a theoretical framework is needed. In the last years, using network models and graph theory to represent the brain structure and function has become a major trend in neuroscience. In this review, we outline how network modelling has been used in neuroimaging, clarifying what are the underlying mathematical concepts and the consequent methodological choices. The major findings are then presented for structural, functional and multimodal applications. We conclude outlining what are still the current issues and the perspective for the immediate future.

HTAC Boiler Fired with Pulverized Coal for Ecologic and Efficient Electricity Production

Schaffel N., Szlęk A., Mancini M., Weber R.

The authors propose a concept of HTAC technology application to the power boilers fired with pulverized coal. So far, HTAC technology was implemented mainly in industrial furnaces fired with gaseous fuels or light oils. In order to investigate the HTAC boiler, several series of numerical simulations have been performed using FLUENT code. A specially emphasis was placed on the main technical and ecological issues that must be considered wherever HTAC technology would be applied in real power station boilers fired with pulverized coal. Mathematical model validation has been done against the experiment performed at IFRF. As an effect of several numerical investigations a final design of the HTAC boiler has been found and the results are presented and discussed in this paper. The proposed HTAC boiler features following major advantages: small size, low harmful substances emission, mainly NOx, high and uniform heat fluxes and very simple construction of the burners. Overall, the present study confirmed that HTAC technology could be a practicable, efficient and clean technology for fossil fuel fired boilers. However, it has to be pointed out that the investigated boiler is only still a concept and before any industrial application much researches have to be done.
