Robust control of shunt active power filter using interval type-2 fuzzy logic controller for power quality improvement

It is well-known that shunt active power filter (SAPF) is widely used to reduce harmonic distortion and to compensate reactive power in electrical power systems.DC bus voltage control of SAPF is very important for excellent power quality.In the control of SAPF, DC bus voltage is controlled by conventional control methods such as PI and PID controll

Assessing the diversity of whiteflies infesting cassava in Brazil

Background The necessity of a competent vector for transmission is a primary ecological factor driving the host range expansion of plant arthropod-borne viruses, with vectors playing an essential role in disease emergence.Cassava begomoviruses severely constrain cassava production in Africa.Curiously, begomoviruses have never been reported in cassa
