Article Synopsis
- A 79-year-old woman was admitted to the hospital due to a month-long history of melena (bloody stools) and anemia caused by chronic gastrointestinal bleeding from cavernous hemangiomatosis in the small bowel.
- She underwent two surgical procedures: an initial laparoscopic jejunal-ileal resection followed by a laparotomic duodenojejunal resection due to ongoing anemia.
- Cavernous hemangiomatosis is a rare condition (7-10% of benign small bowel tumors) that often causes bleeding; diagnosis may involve various imaging techniques, and surgical resection is the preferred treatment method when feasible, considering the risks of extensive surgeries.
Composite material structures are commonly used in many industrial sectors (aerospace, automotive, transportation), and can operate in harsh environments where impacts with other parts or debris may cause critical safety and functionality issues. This work presents a method for improving the accuracy of impact position determination using acoustic source triangulation schemes based on the data collected by piezoelectric sensors attached to the structure. A novel approach is used to estimate the Differential Time-of-Arrival (DToA) between the impact response signals collected by a triplet of sensors, overcoming the limitations of classical methods that rely on amplitude thresholds calibrated for a specific sensor type.
