Innovative glazing systems with silica aerogel in interspace were investigated for energy saving in buildings. Aerogel is a promising transparent insulating material, due to its low thermal conductivity (down to 0.010Wm−1K−1), high solar factor, high daylight transmittance and remarkable...

Energy savings for heating, air conditioning and illuminating plants could be improved by innovative Transparent Insulation Materials (TIMs), which aim to optimize two opposite requirements: transparency and thermal insulation. Aerogel is one of the most promising materials for use in highly...

The present work deals with the problem of monitoring and diagnosis, through non-intrusive methodologies, of stationary internal combustion engine, with particular attention to the cogenerative 1MW unit installed at the Engineering Faculty of the University of Perugia. Specifically, acoustic and...

Expectations are high, but evidence of the impact of microcredit remains in short supply. This article estimates the impact of an urban credit programme in Zambia on business performance and on a range of indicators of wellbeing. Borrowers who obtained a second loan experienced significantly...

This paper uses employer survey data to identify whether and why the probability that a firm uses external advice varies across sectors. The results suggest that the probability of a firm using external advice does vary across sectors and these sector differences can be explained by differences...
