Comparison of Methodologies for the Detection of Multiple Failures Using Acoustic Images in Fan Matrices

Table 1

SVM accuracy rates of the robustness tests for the one faulty fan detection methodology based on training the SVM with one faulty fan parameters.

One faulty fan tests		Accuracy rate (%)
(1) Faultyfaulty fan validation		95.6
(2) Faultyfaulty fans validation
Case A: horizontal/vertical step distance (no central fan)		48.3
Case B: horizontal/vertical step distance (with central fan)		44.1
Case C: diagonal step distance		23.5
Case D: knight movement distance		14.7
Case E: row/column distance		14.2
Case F: diagonal distance		10.9
