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...

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...

Urban areas tend to have much more productive labor and higher salaries than rural areas, and there are vast differences across urban areas. Areas with high salaries and high productivity tend to have employers that invest in much more research and development than areas with low salaries and...

Real estate agents typically charge a 6 percent commission, regardless of the price of the house sold. As a consequence, the commission fee from selling a house will differ dramatically across cities depending on the average price of housing, although the effort necessary to match buyers and...

Most countries exhibit large and persistent geographical differences in wages, income, and unemployment rates. A growing class of place-based policies attempts to address these differences through public investments and subsidies that target disadvantaged neighborhoods, cities, or regions....

Most countries exhibit large and persistent geographical differences in wages, income and unemployment rates. A growing class of "place based" policies attempt to address these differences through public investments and subsidies that target disadvantaged neighborhoods, cities or regions. Place...

We study the long run effects of one of the most ambitious regional development programs in U.S. history: the Tennessee Valley Authority (TVA). Using as controls authorities that were proposed but never approved by Congress, we find that the TVA led to large gains in agricultural employment that...
