Coordinated operation in a multi-inverter based microgrid for both grid-connected and islanded modes using conservative power theory
(2015-10-27)
In order to address the power quality enhancement in a given microgrid, independent control of reactive, unbalanced and distorted load current components, in a multi-inverter-based approach may be required. Therefore, this ...

How to prioritize allocating conservation efforts: An alternative method tested with imperilled herpetofauna
(Wiley Blackwell Publishing, Inc, 2016-02)
Several methods were developed with the aim of prioritizing conservation efforts. However, most of these methods were focused on ranking areas for land protection, without offering alternatives for sites poorly ranked. We ...
Overprediction of species distribution models in conservation planning: A still neglected issue with strong effects
(Elsevier, 2020-12)
Species distribution models (SDM) are increasingly used in conservation planning to identify priority areas for the establishment of protected areas. Nevertheless, the quality of SDM varies widely and may compromise the ...
Hopf solitons and area-preserving diffeomorphisms of the sphere
(Kluwer Academic Publ, 2001-01-01)
We consider a (3+1)-dimensional local field theory defined on the sphere S-2. The model possesses exact soliton solutions with nontrivial Hopf topological charges and an infinite number of local conserved currents. We show ...
