IOT Based Wireless Safety System for Monitoring the Physiological and Environmental Variables of Mine Workers.

The coal mining is essential as well as a risky venture. The miners working here need to handle the extreme environmental condition and the physiological hazardous without specialized examination. A continuous monitoring of the environmental change and the physiological variables is needed in order to enhance the condition for people and the equipment. A Continuous monitoring of the environmental gases and the physiological variables is the major challenge and need to be followed for safety of workers working in mine. This paper present the design and the implementation of real time monitoring device to measure the physiological variables and the gases present in the mining. The proposed system consists of physiological variables, ECG signal, respiratory activity, body temperature, fall detection and also the environmental gases. The sensors will be embedded throughout the T-shirt to measure the variables. The device will monitor the real time data and wireless communication network will be provided by using Wi-Fi link module. By using IOT it is easy to upload the data on the web server and it also provides data security.

Sizing Extreme Environmental Condition Influences on the Multiphase Polymeric Composites’ CTE

The coefficient of thermal expansion (CTE) of multiphase polymeric composite materials represents an important role in the process of engineered materials design, especially while approaching thermal management issues. Tailoring and designing material combinations in order to develop a composite structure to prove stability over a wide range of temperatures, from cryogenic to high values, to withstand extreme environmental conditions is the dream and the purpose of any engineering team involved in such study/research area. The paper aims to approach and to present the variations of the CTE with extreme environmental conditions (e.g. cryogenic, desert and hygroscopic conditioning) for particular combinations of particle-fibers multiphase polymeric composite materials. Influencing factors will be underlined to accompany the experimental research.
