<p>This paper reports the early findings of an ongoing project aimed at developing new methods to upgrade the current maintenance strategies of the civil and transport infrastructure. As part of these new methods, the use of Machine Learning (ML) algorithms is being investigated to constitute the core of a new generation of more accurate and robust structural health monitoring (SHM) systems for concrete structures. Unlike most of the existing SHM systems, relying on the analysis of the natural frequencies of the structure based on data obtained from accelerometers, the present study uses a distributed optic fiber system to monitor the strain distribution along steel reinforcing bars. The preliminary results of the study indicate that a semi-supervised Deep Autoencoder algorithm (DAE) can successfully quantify the damage attributable to transverse cracks in a reinforced concrete beam subjected to three-point loading. Future applications will feature the determination of crack locations, early detection of reinforcement corrosion as well as other types of damage such as splitting cracks or surface spalling.</p>

Multi-soliton propagation in an inhomogeneous optic fiber medium with frequency chirping has been analyzed in this paper. The two-soliton solution for the nonlinear Schrodinger equation within the integrable limit has been constructed using Backlund transformation technique and a recursive method. As the multi-soliton propagates through the inhomogeneous fiber, the traveling pulse gets compressed and amplified, which supports multi-soliton pulse compression technique. The inhomogeneous optic fiber system for varying GVD parameters has also been studied using variational analysis and numerical methods. As the pulse propagates through the inhomogeneous optic fiber, its width decreases and amplitude increases, which is similar to the case of adiabatic compression of solitons.
