1. Experimental Principle (Direct Wave Propagation)

Unlike reflection/echo testing, Phone 1 (Master Sender) transmits a continuous vibration or wave packet into the structure, and Phone 2 (Receiver) captures the incoming wave exactly 30 meters apart. The Time-of-Flight ($\Delta t$) corresponds to the direct propagation time across the material span $L$.

2. Two-Phone Setup & Master Workflow

• Supervisor Cue: Students standing 30m apart start their respective phones on the supervisor's command.
• Handling Start Delays: Even if Phone 2 starts 1 second late, Master Phone 1 acts as King ($T_0$ absolute reference).
• Master Synchronization: Bring Student 2's Receiver CSV to Phone 1, upload both files in Section 3, and run the multi-algorithm suite.

3. Multi-Algorithm Suite Included

The app tests your structural data against 6 distinct AI models (3 Classical Machine Learning models + 3 Quantum AI models) to guarantee rigorous academic analysis without relying on a single method.
