Feature based video stabilization based on boosted HAAR Cascade and representative point matching algorithm
The success of handheld video capturing devices has further fueled the need of improved video stabilization. The videos often contain many foreground facial features like eyes, nose etc. These foreground features can be ...
Defining a fish bio-assessment tool to monitoring the biological condition of a cascade reservoirs system in tropical area
(Elsevier B.V., 2014-08-01)
We studied five tropical reservoirs in the cascade system of the Tiete River (State of Sao Paulo, Brazil) in order evaluate the suitability of a fish multimetric index (Reservoir Fish Assemblage Index-RFAI) as a bio-assessment ...
Frugivory and seed dispersal by tapirs: an insight on their ecological role
(Wiley-Blackwell, 2013-03-01)
Tapirs are one of the last extant megafauna species that survived the Pleistocene extinctions. Given their size and digestive system characteristics, tapirs might be the last potential seed disperser of plant species that ...
Discrete Time Nested-Loop Controller for the Output Stage of a Photovoltaic Microinverter

Defaunation and fragmentation erode small mammal diversity dimensions in tropical forests
(2018-01-01)
Forest fragmentation and defaunation are considered the main drivers of biodiversity loss, yet the synergistic effects of landscape changes and biotic interactions on assemblage structure have been poorly investigated. ...
Ion cyclotron instability due to the thermal anisotropy of drifting ion species
(Blackwell Publishing Ltd, 2003)
In a recent study of ion cyclotron waves generated by the thermal anisotropy of oxygen ions, it was shown that the heavy ion drift velocity and a large thermal anisotropy of the heavy ions can destabilize proton-cyclotron ...
