In this paper the findings are reported from an experimental study of the heat transfer and flow created between two vertical parallel walls heated from one side. In the laboratory a mock up of a facade provided with photovoltaic elements (PV) was built. Surface and air temperatures were...

The impetus of this paper is to analyse numerically the fluid flow and heat transfer characteristics of buoyancy-driven convection between two vertical parallel walls, heated from one side. Both convection and radiation heat exchanges are considered as the heat transfer mechanisms by which the...

The impetus of this paper is to analyse numerically and experimentally the flow and heat transfer characteristics of buoyancy-driven air convection behind photovoltaic panels. Both convection and radiation heat exchanges are considered as the heat transfer mechanisms by which the thermal energy...

This paper argues that the notion of interdependence between technologies and institutions which Dalum, Johnson, Lundvall (in Lundvall ed,. 1992) incorporate in the national system of innovation (NSI) approach is valid not only on the national level, but also on all levels of social...

This paper suggests that specific circumstances provide substantial - and historic - opportunities for Poland as a pioneer of a 'greener post-communism'. These are: the paradoxical effects of membership in the Soviet bloc which present the Polish reformers with important opportunities for...

This article uses Polity IV data to probe system dynamics for studies of the global diffusion of democracy from 1800 to 2000. By analogy with the Bass model of diffusion of innovations, as translated into system dynamics by Sterman, the dynamic explanation proposed focuses on transitions to...
