Localized field-aligned currents and 4-min TEC and ground magnetic oscillations during the 2015 eruption of Chile’s Calbuco volcano
(SpringerOpen, 2016-08-31)
The Calbuco volcano in southern Chile erupted on April 22, 2015. About 2 h after the first eruption, a Swarm satellite passed above the volcano and observed enhancement of small-amplitude (~0.5 nT) magnetic fluctuations ...
Multidecadal change in streamflow associated with anthropogenic disturbances in the tropical Andes
(2015)
Andean headwater catchments are an important source of freshwater for downstream water users. However, few long-term studies exist on the relative importance of climate change and direct anthropogenic perturbations on flow ...

Analysis of the Influence of IPFC-POD and PSS controllers coordinated tuning by an Adaptive Genetic Algorithm with Hyper-mutation
(Ieee, 2018-01-01)
Small-magnitude disturbances happen to produce electro-mechanical oscillations which should be damped as quickly as possible to ensure reliability and stability of electrical power system (EPS). Flexible AC transmission ...

The 1877–1878 El Niño episode: associated impacts in South America
(Climatic Change, 2009-08)
At times when attention on climate issues is strongly focused on the assessment of potential impacts of future climate change due to the intensification of the planetary greenhouse effect, it is perhaps pertinent to look ...
Optimal wave energy extraction for oscillating water columns using second-order sliding mode control
(Institution of Engineering and Technology, 2020-07-06)
Ocean waves are an important renewable energy resource and several fields of R&D are concurrently working to improve technologies for harnessing their power. In that context, this study presents a control to optimise the ...
