Passivity based control of DC motor in sensorless configuration is proposed in this paper.Exact tracking error dynamics passive output feedback control is used for stabilizing the speed of Buck converter fed DC motor under various load torques such as constant Headlight Cover type, fan type, propeller type, and unknown load torques.Under load condi
The torsion pendulum at the heart of the apparatus to measure the gravitational constant, $G$ at the Bureau International des Poids et Mesures (BIPM) is used to measure the gravitational torque between source and test-mass assemblies with two methods.In the Cavendish method, the pendulum moves freely.In the electrostatic-servo method, Gift Set the
Background: The quest for scientific endorsement of new drugs from plants continues due to the rising antibiotic resistance against pathogenic bacteria.Litsea iteodaphne is used in Sri Lanka in the treatment of infectious diseases.Therefore, in vitro antibacterial activity of L.iteodaphne plant extracts were evaluated against selected human pathoge
The tomato is a widely cultivated and consumed vegetable globally.Comarca Lagunera is an important tomato-exporting region of Mexico.Salinity is an abiotic factor that reduces productivity and increases production costs.To advance growing period, there is high demand for the sustainable production of seedlings.Plant-growth-promoting rhizobacteria (
