The increasing consumption of the electric energy aimed at develop transmission networks and demand for higher reliability from network; in this regard, wide-area measurement systems using phasor units (PMUs) have revolved trend power network management. In paper, optimal allocation PMUs order to reach perfect observability based on a differential evolution algorithm, is proposed it shown that,...

This document discusses the use of impedance pneumography as a technique to measure respiration rate. The generation of high-frequency ac current source is described, and the issues related to delay in modulated signal and finite transition times of carriers are addressed. The report also includes descriptions of potential implementations of a respiration rate measurement system using the ADS12...

Assessing ageing infrastructure is a critical challenge for civil engineers due to the difficulty in the estimation and integration of uncertainties in structural models. Field measurements are increasingly used to improve knowledge of the real behavior of a structure; this activity is called structural identification. Error-domain model falsification (EDMF) is an easy-to-use model-based struct...
