Material point method (MPM) is a mesh based particle method which is suitable to simulate applications with large deformations. MPM adopts two discretisations, one is the space discretisation where the equation of motion ...

The wind sectors pends roughly 2200M€ in repair the wind turbines failures. These failures do not contribute to the goal of reducing greenhouse gases emissions. The 25–35% of the generation costs are operation and maintenance ...

This paper presents thunderstorm electrostatic field measurements carried out by electric field mills located at mountainous regions in Spain and Colombia. The profile of electric field changes ¿E due to lightning vs ...

The effects of thermal pre-treatments on the biogas production potential of two solid slaughterhouse waste types (poultry and piggery slaughterhouse by-products) were assessed by means of batch experiments. Both animal ...

Tillage systems modify, at least temporarily, some of the physical properties of soil, such as soil porosity. Tillage also has an indirect effect on soil water content throughout the growth cycle, particularly in areas ...

This paper analyzes the second best time-varying toll pattern design issue, with a focus on parameters such as the degree of toll variation between time intervals, the minimum toll fare and the gap with the peak period ...

Present 3D printing technology allows the efficient design and construction of structures with complex shapes and high porosity satisfying biological and coastal protection demands. In this case, an array of ultra-porous ...

RC slabs can be subjected to transverse loads and in-plane tensile forces simultaneously, as it occurs in top slabs of continuous box girder bridges at intermediate supports, or in floor slabs supported on columns and ...
