This article discusses the conceptual basis and the criteria for the installation of a centralized measurement system in the Baixada Fluminense, sub area of concession of the electricity utility of Rio de Janeiro (Light Energia). The study estimates the energy consumption and the average revenue that results from the implementation of the proposed facility to replace the traditional measurement system in place. The sub area of concession selected was defined based on the following two characteristics: area associated with high rate of electricity losses and vulnerability of the power grid exposed to the community. The methodology used to develop the work included a literature review on systems of electricity metering and a study of the socioeconomic profile of the selected region. The impact of the proposed technological change on the energy consumption was statistically evaluated based on the nonparametric Wilcoxon Test. Based on real data from municipalities located in the region, an analysis of energy consumption behavior was carried out before and after the proposed alternative technology was implemented.

Smart meters are essential tools to increase energy efficiency of buildings and grid. However, to get a real benefit from them, an effective integration between the different energy domestic metering devices and display, as well as a suitable post-processing of such a big amount of measurement data is crucial. In this paper the authors present a new integrated smart metering system for home applications. This system is able to acquire data consumption of electricity, gas, heat meters and to convey it on a single smart platform able to process and give back to the user useful information about the efficiency and the health of its power plant.

In natural disaster mitigation, many methods and systems are being developed to reduce the effects cause by the phenomena to the lowest possible level. We introduce a landslide monitoring system based on wireless sensor network with strong processing nodes. For this system, a management scheme is necessary for operators to perceive the status of the system. The scheme being constructed has a potential to apply to similar systems if they possess same characteristics with this system.

The simple laboratory model of dissipative fault was built. Two granite cubes were pressed together using a custom made device. When one of the blocks was knocked, the resulting vibration of the other was monitored in the form of local temperature change. The other experiment included the measurement of the friction coefficient for the rock with a smooth as well as a rough surface. In this way we tried to assess energy dissipation of solitary seismic wave crossing the fault.

Nowadays the measurements take place an important role in our life. In order to prevent some unpleasant situations, we try day by day to assure environmental conditions that protect us against some accidents due to explosion or high level of toxicity that can occur, in working environment and confined spaces. The article presents the statistical characteristics of a monitoring system consisting of 17 calibration stations connected to a server in a secured network and a number of 373 gas analysers. The measurement data, downloaded from each analyser are stored, analysed, processed, reported and archived for later documentation. The monitoring system, created by Dräger technology which assure a high protection of life within the sectors surrounding in the vicinity of wastewater plants, where we can find the gasses such as CH₄, H₂S, CO, lack of O₂ and so on. In order to demonstrate the performance of calibration stations, the performance parameters Z_score and E_n number were calculated using data from 40 gas analysers.
