The corrosion of reinforced concrete without and with the addition graphite powder low carbon content was evaluated. Phase identification processes physical-electrochemical properties were analyzed using X-ray diffraction techniques (XRD), scanning electron microscopy (SEM), half-cell potential, electrochemical noise (EN) linear polarization resistance (LPR). Samples studied for 168 days in sal...

In this paper, we propose a noise robust bottleneck feature representation which is generated by an adversarial network (AN). The AN includes two cascade connected networks, an encoding network (EN) and a discriminative network (DN). Melfrequency cepstral coefficients (MFCCs) of clean and noisy speech are used as input to the EN and the output of the EN is used as the noise robust feature. The ...

An important signaling process in the nervous system is the release of chemical messengers called neurotransmitters from neurons. In this thesis alternative thin film electrode materials for applications targeting electrochemical detection of neurotransmitters in chip devices were evaluated. Microelectrodes made of the conductive polymer Pedot:tosylate were characterized with respect to their p...

The propagation of localized corrosion on API 5L X65 carbon steel in hydrogenocarbonated solution containing chloride ions was monitored during long immersion times by electrochemical noise (EN) measurements ZRA mode. Monitoring from the EN amplitude is possible but interpreting potential and current transients after made difficult different processes (metastable or stable pits, crevices, produ...
