Diesel - electric traction is a well established technology in railways systems, mainly for lines with a low traffic potential. In those conditions, the choice of a diesel powered locomotive is due to the reduced costs compared to the infrastructure cost o ...

Previous taxonomies of software evolution have focused on the purpose of the change rather than the underlying mechanisms. This paper proposes a taxonomy of software evolution based on the characterizing mechanisms of change and the factors that influence ...
The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of importance for global climate modelling and defines critical gaps needed to reduce the involved uncertainties. All pieces required for the representation of OA in a global ...
The distinction between dual rental systems and unitary rental markets is refined and developed. In particular, unitary rental markets are defined as markets in which barriers to nonprofit providers competing on the rental market are removed, reserving the ...
This study presents continued development of the Nenes and Seinfeld (2003) cloud droplet activation parameterization. First, we expanded the formulation to (1) allow for a lognormal representation of aerosol size distribution, and (2) include a size-depend ...
Pulse-like carbon dioxide release to the atmosphere on centennial time scales has only been identified for the most recent glacial and deglacial periods and is thought to be absent during warmer climate conditions. Here, we present a high-resolution carbon ...

Combined loading and climatic effects associated with the choice of high modulus bituminous mixtures, in order to prevent the pavements from rutting, have increased the risk of cracking failure in the bituminous layers. It was decided, in 1989, to start a ...
Significant progress has been made towards making ad hoc networks secure and DoS resilient. However, little attention has been focused on quantifying DoS resilience: Do ad hoc networks have sufficiently redundant paths and counter-DoS mechanisms to make Do ...
Anthropogenic increases in atmospheric carbon dioxide (CO2) concentrations may affect vegetation distribution both directly through changes in photosynthesis and water-use efficiency, and indirectly through CO2-induced climate change. Using an equilibrium ...
