The growing number of renewable energy replacing conventional generators results in a loss of the reserve for frequency control in power systems, while many industrial power grids often have excess energy supply due to abundant wind and solar energy resources.This paper proposes a secondary frequency control (SFC) strategy that allows industrial po
Reconstructed human adipose tissues represent novel tools available to perform in vitro pharmaco-toxicological studies.We used adipose-derived human stromal/stem cells to reconstruct, using tissue engineering techniques, such an adipose tridimensional model.To determine to what extent the in vitro model is representative of its native counterpart,
This study used multi-stage remote sensing data in the analysis of the evolution of deep-seated landslides at Putanpunas stream, Taiwan.Terrain analysis, landslide interpretation, and the assessment of underlying mechanisms were included.Our results show that the evolution of deep-seated landslides can be divided into four stages: (1) erosion and S
