Nowadays, solar resource estimation via clear-sky models is widely accepted when correctly validated with on ground records. In the past, different approaches have been proposed in order to determine clear-sky periods of solar radiation on-ground records: visual inspection of registers, discretization via a threshold value of clear sky index, and c...

General purpose computing on graphics processing units (GPGPU) is a promising technique to cope with nowadays arising computational challenges due to the suitability of GPUs for parallel processing. Several libraries and functions are being released to boost the use of GPUs in real world problems. However, many of these packages require a deep know...

This article presents a small prefabricated building with constructive systems not usually utilized in Spain, together with the structural checking needed before its construction. The principal material is the black poplar plywood panel. These wood-derived panels may enhance building sustainability and lighten their weight, showing new business opp...

Solar irradiation databases from satellite estimates are based on images taken from satellites with wide spatial resolution. The rising interest on solar energy technologies and climate change suppose the necessity of high spatial resolution data of solar irradiation. The downscaling of satellite estimates provides an alternative to dense pyranomet...

Rubber profile manufacturers are aiming to develop CFD models of their extrusion dies to optimize die design. Real extrusion dies are characterized by an intricate geometry derived from the elaborated profiles demanded by automotive industry as well as the turning and narrowing ducts in dies. To obtain well performing simulations, the major challen...

The paper deals with the complexity of rubber mixture process. The main issue is to develop well performing on-line soft sensors to monitoring rheological rubber properties. When mixing all raw materials, continual discards of defective materials with high costs associated can be caused by unexpected process variations and incorrect operating set p...
