متن کاملDetecting Concept Drift in Data Stream Using Semi-Supervised Classification
Data stream is a sequence of data generated from various information sources at a high speed and high volume. Classifying data streams faces the three challenges of unlimited length, online processing, and concept drift. In related research, to meet the challenge of unlimited stream length, commonly the stream is divided into fixed size windows or gradual forgetting is used. Concept drift refer...
متن کاملPreliminary Study of Pesticide Drift into the Maya Mountain Protected Areas of Belize
In Belize, Central America, many farms surrounding the Protected Areas of the Maya Mountains rely heavily on the application of agrochemicals. The purpose of this study was to test whether orographic drift of glyphosate and organophosphates into the nearby Maya Mountain Protected Areas occurred by collecting phytotelmic water from seven sites over 3 years. Regardless of location within the Maya...
متن کاملContrasting behavioural responses of grazing mayflies and detritivorous caddisflies to predatory fish
Invertebrates living in streams where predatory fish are present are often able to detect them through waterborne chemical cues and respond with behavioural changes that lower predation risk. We hypothesised that behavioural responses to a predatory fish (brown trout, Salmo trutta) would be stronger in grazing mayflies (Baetis sp. and Epeorus sp.) than in detritivorous caddisflies (Potamophylax...
متن کاملPHYSIOLOGICAL DOSE-RESPONSE OF COFFEE (Coffea arabica L.) PLANTS TO GLYPHOSATE DEPENDS ON GROWTH STAGE
Glyphosate is the main herbicide used in coffee (Coffea arabica L.) plantations in Brazil. Problems with herbicide drift commonly occur in orchard fields due to non-adequate spraying conditions. A series of experiments was carried out aiming to evaluate physiological dose-response of C. arabica plants submitted to exposure to simulated glyphosate drift in two distinct plant growth stages. Glyph...
