A machine learning approach to determine the elastic properties of printed fiber-reinforced polymers
This work focuses on the simultaneous determination of elastic constants and fiber orientation state for a short fiber-reinforced polymer composite by performing minimum experimental tests. We introduce methodology that enables inverse in-situ properties tensile tests at coupon level. demonstrate approach extrusion deposition additive manufacturing (EDAM) process to illustrate one application m...
BACKGROUND Ankylosing spondylitis (AS) is a chronic inflammatory disease of spine and sacroiliac joints; it is characterized by new bone formation, and the disease processes can be accompanied by osteoporosis. In the present study, we investigated changes in bone mineral density (BMD) and in the levels of various bone turnover-related biomarkers and cytokines in a cohort of AS patients, with re...
