Wind farm power density optimization according to the area size using a novel self-adaptive genetic algorithm

Fernando Porté Agel, Nicolas Otto Kirchner Bossi

This work studies the power density (PD) optimization in wind farms, and its sensitivity to the available area size. A novel genetic algorithm (PDGA) is introduced, which optimizes PD and the turbine layout, by self-adapting to the PD and to the solutions ...

Design of Load-Bearing Systems for Open-Ended Downstream Reuse

Corentin Jean Dominique Fivet

This paper discusses the design of load-bearing systems for buildings with regard to their current lack of open-ended reusability. The reason for dismantling load-bearing systems today tends to be less related to material degradation than to a loss of func ...

A Grammar of Muqarnas: Drawings of the Alhambra by Jones and Goury (1834-1845)

Ignacio Ferrer Perez-Blanco

The muqarnas of the Nasrid Alhambra stand out as one of the most singular architectural episodes o f Medieval Islamic art due to their sophisticated three-dimensional construction, whose layout remains little known. In 1834 and 1837, the architects Owen Jo ...
