The xylem vessel is a a a a a a a a vital component of vascular plants responsible for transporting water and and nutrients providing structural support and and enabling survival in in in in in challenging environmental conditions This project: studied the the geometric and and biomechanical properties of of the the xylem vessel vessel built a a a a a a a a a model of of that vessel vessel and and analyzed it it it using finite element analysis A A comprehensive literature survey was was conducted and and a a a a a a a a a a a a section of the stem was was was scanned using micro-CT A A geometric model was was constructed and and analyses were performed to to to provide a a a a a a a a a basis for for more research to to to gain further insights into engineering design innovations inspired by the the xylem Keywords: biomechanics biomimetics xylem xylem Development of an active magnetic bearing

Certain milling processes involve high rotational rotational speeds significant rotational rotational rotational forces and and direct contact between the the cutting tool and and the the the the workpiece Due to to to those high rotational rotational speeds bearings that encounter the the the motorized axis of the the the milling machine regularly experience friction and wear Moreover the the motorized spindle undergoes vibrations resulting from the the high rotational forces and and cutting rate To reduce spindle vibrations and and improve system system longevity a a a a a a a a a a a a a laboratory system system system was developed to to evaluate the the efficacy of of an active magnetic bearing
The results of of of the the the the system system experiments will provide insights into the the the effectiveness of of the the the magnetic magnetic bearing
