Location Signature Test

This work presents an experimental test of location defined as a degree-of-freedom resolved structural state. Using controlled excitation and spectral response analysis, the study evaluates whether identical systems exhibit distinct structural signatures under varying constraint configurations.

The framework constructs location signatures from spectral features and examines their variation under controlled changes in system configuration. Results demonstrate systematic variation in spectral structure consistent with constraint-dependent accessibility of modes.

The study establishes a reproducible pathway for evaluating location as a structural property derived from system response. Full experimental methodology and analysis are restricted pending further development.
