... emission ( AE ) multi-frequency domain features and random forest ( RF ) algorithms, enabling effective detection of such micro-leaks. Design/methodology/approach AE signals from pinhole leaks (aperture sizes: 0.1, 0.2 and 0.35 mm) under actual operating pressures (0.1, 0.2 and 0.3 MPa) were...

... in rehabilitation and communication. Design/methodology/approach The proposed RF-GRA system is a noncontact gesture recognition framework for aphasia patients: it uses RFID phase data for precise gesture tracking, adopts a hierarchical random forest for high-accuracy identification, optimizes real-time...
