    Abstract: This paper presents an intelligent fault detection based on adaptive continuous wavelet transform of broken rotor bars for Induction Motor (IM). Broken rotor bars, bearing decay, eccentricity, as motor faults appears as different frequencies in the stator current signals. The stator current and speed signals at deferent operation conditions obtaine... Show More

    Abstract: Wheat is one of the most important cereal cultivated in Ethiopia. It ranks fourth after Teff (Eragrostis tef), Maize (Zea mays) and Sorghum (Sorghum bicolor) in area coverage and third in total production. But, its production and productivity is prone to divers biotic and abiotic factors. Among biotic factor diseases are the one. But, the relative ... Show More
