Abstract: We propose to evaluate the level of eutrophication of surface water in the middle reaches of the river Belaya in the vicinity of the town of Sterlitamak using "eutrophication factor", as the main indicator used by the average length of seedling cress in undiluted samples. We selected a few water samples in eight gauges above, below and within the city. We consider the seasonal dynamics of the level of eutrophication of the variability in different years (2011-2016). Statistical analysis of the data revealed positive and negative dependence. Studies show high nutrient content in this water body. Thus, our proposed method can be used to determine the level of eutrophication of different water bodies.

Abstract: Presently, there is a lack of effectiveness in the manufacturing of sensors and sensing systems, with Brazilian technologies and raw-materials, able to measure soil water content, with efficiency and practicality. On account of this, ceramics is selected as sensing elements for this application, based on relevant results obtained by researchers from the TECAMB Group of INPE, along the last 15 years. In this way, the present work tries to bring together the technologies of manufacturing, characterization and development of porous ceramics and the monitoring of soil water content in typical Brazil soils, for several applications, such as irrigation, drainage, building and environmental monitoring as well. And so, in order to improve the sensing capacity of these ceramic devices, electrical measurements were performed in different climatic conditions of controlled relative humidity and room temperature. The scanning electron microscopy technique was applied for the morphological analysis of the sintered ceramic microstructure. Results evidenced that the ceramic devices presented a very promising response to the water molecules contained in soil samples selected for tests, under established climatic conditions.

Abstract: This paper presents a composite system implemented with wireless sensor networks for monitoring and controlling the operation in welding environments which raises issues regarding work conditions: air quality (dust particles concentration), climate stress (environmental parameters) and wireless transmissions (tracking, remote operation) with the aim of minimizing work risks and maximizing operator’s safety and health. The wireless interface with the work environment which allows remote operation was developed by the authors using hardware platforms with ZigBee and Wi-Fi transceivers and software based on virtual instrumentation. The results obtained in the welding environment by performing remote measurements based on PM (particulate matter) analysis, sensor data and received signal strength (RSS) have shown that it is possible to detect the areas affected by fumes and with improper climate conditions, to track hazardous objects and to control operations in real-time.

Abstract: Environmental monitoring plays a very important role in the activities of predicting and protecting environments and society. The activities are included of monitoring environmental parameters continuously, predicting and evaluating the effects of environments on society, warning immediately the abnormal phenomenon or pollution due to environmental changes, making data base etc. In the paper, we will present our proposal of design and implementation of a kit monitoring environmental parameters such as temperature, humidity, pH, salt percentage, water level, etc remotely through internet. Obtained data will be monitored, handled, managed, reported. The system has been used to monitor environmental parameters to evaluate the waste water in industrial zones in Hochiminh City, Vietnam.

Abstract: ESOUNDMAPS is an ongoing research program that aims in developing a wireless audio sensor network (WASN) and deploying it at the surrounding environmental area of the Technological Institute of Piraeus in Attica, Greece. The proposed WASN will be used for the environmental monitoring of the area and aims to be used in the future for assessing the impact of human generated noise to the wildlife. Collected sound samples will be forwarded by the sensor nodes to a central server where they will be automatically evaluated with respect to their identity; environmental sound maps will be generated based on the evaluation of these sound samples. High-level sound classification is defined herein as the act of classifying a sound sample to three broad categories namely anthropogenic, biophysical (other than human) and geophysical sounds. In this paper we present an integrated platform that includes sound sample denoising using wavelets, feature extraction from sound samples and Gaussian mixture modeling of these features, and a powerful two-layer neural network classifier for the automated high-level classification of incoming sound samples. Classification results, obtained using digital sound samples, exhibit outstanding classification accuracy (sometimes reaching or exceeding 98% correct vs. incorrect estimates), thus demonstrating the feasibility of the proposed approach in realistic environments.
