Determining the drift potential of Venturi nozzles compared with standard nozzles across three insecticide spray solutions in a wind tunnel
BACKGROUNDPrevious research has sought to adopt the use of drift-reducing technologies (DRTs) for use in field trials to control diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Plutellidae) in canola (Brassica ...
An Overview on Concepts Drift Learning
(Ieee-inst Electrical Electronics Engineers Inc, 2019-01-01)
Concept drift techniques aim at learning patterns from data streams that may change over time. Although such behavior is not usually expected in controlled environments, real-world scenarios can face changes in the data, ...
On the variability of equatorial F-region vertical plasma drifts
We use incoherent scatter radar measurements from the Jicamarca Observatory to study the variability of equatorial F-region vertical plasma drifts. The daytime average upward drifts do not vary much with solar activity, ...
Quiet time equatorial F region vertical plasma drift model derived from ROCSAT‐1 observations
(American Geophysical Union, 2008-05-03)
We have used five years of measurements on board the ROCSAT‐1 satellite to develop a detailed quiet time global empirical model for equatorial F region vertical plasma drifts. This model describes the local time, seasonal ...
Equatorial zonal plasma drifts measured by the C/NOFS satellite during the 2008–2011 solar minimum
(American Geophysical Union, 2013-06-26)
We use the measurements by the Vector Electric Field Investigation (VEFI) on board the Communication/Navigation Outage Forecasting System (C/NOFS) satellite to study the local time and seasonal‐ and longitudinal‐dependent ...
Evaluation of Low-Drift Nozzles in Agrochemical Applications in Orchards

Equatorial ionospheric zonal drift model and vertical drift statistics from UHF scintillation measurements in South America
(European Geosciences Union, 2004-09)
UHF scintillation measurements of zonal ionospheric drifts have been conducted at Ancon, Peru since 1994 using antennas spaced in the magnetic east-west direction to cross-correlate geo-synchronous satellite signals. An ...
Particle Competition and Cooperation in Networks for Semi-Supervised Learning with Concept Drift
Concept drift is a problem of increasing importance in machine learning and data mining. Data sets under analysis are no longer only static databases, but also data streams in which concepts and data distributions may not ...
