Abstract: We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNLL accuracy respectively, suitable for use in(More)
—Co-simulation platforms are necessary to study the interactions of complex systems integrated in future smart grids. The Virtual Grid Integration Laboratory (VirGIL) is a modular co-simulation platform designed to study interactions between demand response strategies, building comfort, communication networks, and power system operation. This paper presents(More)
Small-x logarithmic enhancements arising from high-energy gluon emissions affect both the evolution of collinearly-factorized parton densities and partonic coefficient functions. With the higher collider energy reached by the LHC, the prospect of a future high-energy collider, and the recent deep-inelastic scattering (DIS) results at small-x from HERA,(More)
Simulation is widely used to assess and/or improve the energy efficiency of both existing and new buildings. Such an analysis has to account for heterogeneous phenomena efficiently, to manage components in a modular manner, and (which is seldom addressed in a struc-tured way) to scale the detail level in all or part of the model, based on the particular(More)
Simulation is important to evaluate the energy-related performance, of a building, and for reliable results, reproducing the behaviour of the contained air volumes is particularly relevant. This is especially true if the control system is considered as part of the simulation study, for example to determine the best sensor positioning. For such a purpose,(More)
Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilisation of data centre resources. On the other hand, the increased usage of ICT, jointly with the increased cost of energy, make designing and managing data centres with energy efficient strategies a crucial and strategical(More)
Simulation is important to evaluate the energy-related performance of a building, and for reliable results, reproducing the behaviour of the contained air volumes is particularly relevant. For such a purpose, fully mixed models (i.e., for instance, a single temperature per room) easily prove inadequate, while Computational Fluid Dynamics (CFD) ones are too(More)

Energy simulation programs are increasingly used to assess the energy performance of buildings and heating, ventilation, and air conditioning (HVAC) systems during design. Faults during operation can lead to considerable increase in energy use and associated operating costs. In 2009, 13 of the most common energy faults in U.S. commercial buildings were(More)
