Passivity based control of DC motor in sensorless configuration is proposed in this here 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 type, fan type, propeller type, and unknown load torques.Under load conditions, sens
Friction stir extrusion is an innovative direct-recycling technology for metal machining chips.During the process a specifically designed rotating tool is plunged into a cylindrical here matrix containing the scraps to be recycled.The stirring action of the tool prompts solid bonding related phenomena allowing the back extrusion of a full dense rod
Forests both support biodiversity and provide a wide range of benefits to people at multiple scales.Global and national remote sensing analyses of drivers of forest change generally focus on broad-scale influences on area g35 coupe fender (composition), ignoring arrangement (configuration).To explore meso-scale relationships, we compared forest com
In silico trials recently emerged as a disruptive technology, which may reduce the costs related to the development and marketing approval of novel medical technologies, as well as shortening their time-to-market.In these trials, virtual patients are recruited from a large database and their response to the therapy, such as the implantation of a me
