We apply the differential evolution algorithm (DE) to interrogate a fiber Bragg grating sensor network, where a multi-level crossing detector comprising of reference gratings is used to track the sensor gratings which have the same Bragg wavelength but different reflectivities. The DE algorithm uses a numerical model of the system and the data collected from the network, for wavelength demodulation and direct extraction of the perturbation on each of the sensor. We show that the estimated signals are in good agreement with the actual signals. The use of DE algorithm facilitates faster data collection and offline interrogation.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
