Fire tests were conducted on a quarter-scale model of an aircraft cabin to determine ventilation effects on temperature and smoke. The ventilation rates were varied between 1 1/4 and 2 1/2 minutes' time for an air exchange (quarter scale) . The data indicate that there were no significant changes in the cabin temperatures and in the quantity of hea

This project developed and validated an inverse problem framework for truss bridges that uses displacement as the primary diagnostic input. Displacement histories are extracted from single-camera video by optical flow tracking, modal parameters are identified by output-only methods with bootstrap uncertainty quantification, and element-level damage
