In many places of the world, the interruption of touristic activities in the aftermath of a catastrophic earthquake is often neglected in the evaluation of seismic risks; however, these activities can account for a significant proportion of short-term and long-term economic impacts for these regions.In the last decade, several rapid visual screenin
During expiration, the carbon dioxide (CO2) levels inside the dead space of a filtering facepiece respirator (FFR) increase significantly above the ambient concentration.To reduce the CO2 concentration inside the dead space, we attach an active lightweight venting system (AVS) comprising a one-way valve, a blower and a battery in a housing to a FFR
The first step in generic video processing is temporal segmentation, i.e.shot boundary detection.Camera shot transitions can be either abrupt (e.g.cuts) or gradual (e.g.fades, dissolves, wipes).Sports video is one of the most challenging domains for robust shot boundary detection.We junk baller band proposed a shot boundary detection algorithm for
Phosphorus (P) is one of the most important elements used in fertilizing soils in tropical regions due to the low efficiency of phosphate fertilization.This work aimed to fractionate inorganic P (Pi) in tropical soils of different mineralogical compositions and to relate these fractions with their respective phosphate buffer capacity (PBC) indicato
