Coal continues to be mined in over 50 countries. Coal accounts for approximately 64% of India's electricity. Spontaneous explosions in the coal mines are one of the most common accidents. The main cause for mine explosions is the presence of toxic methane gas in an environment with insufficient oxygen. Gas detection is crucial for explosion prediction.(More)
Diabetes is one among the supreme health challenges of the current century. Most common method for estimation of blood glucose concentration is using glucose meter. The process involves pricking the finger and extracting the blood along with chemical analysis being done with the help of disposable test strips. Non-invasive method for glucose estimation(More)
Wireless communication systems play an increasingly integral role in society. Currently underground sensor networks are used in many applications for security purposes, environmental applications, infrastructure maintenance etc. The major problem, associated with sensor networks, is in providing the power supply to enable the networks to work for long(More)
Diving has become a prevalent way of performing research in underwater environments. One of the major concerns with diving is the health issues faced by the divers during deep sea dives which call for the necessity of a reliable health monitoring system. The paper mainly focuses on the architectural design of an intelligent remote health monitoring system(More)
Driving at night causes approximately 50% of traffic fatalities; one of the primary causes being the usage of headlights on high beam. Courteous drivers usually lower their headlights from high to low beam when they see oncoming traffic. However, due to driver inertia, either inherent and/or caused by frequent switching between high and low beams,(More)
Lung infections and lung diseases are common and can be potentially deadly. Hence preventing lung diseases is more mandatory than curing them. Specialist doctors are less available in rural areas compared to urban areas. Thus it has become necessary to develop some method by which people in remote areas can be monitored by specialist doctors who might be(More)
The safety of fishermen in small fishing vessels is of continuing concern as there are many reports of fishing vessel - ship collisions along the Western coast of India. These accidents are mainly caused due to the over reliance on the radar systems which fail to detect small boats or due to the negligence from the side of the shipping crew. This paper(More)
Water is an important natural resource which needs constant quality monitoring for ensuring its safe use. This paper introduces a river water quality monitoring system based on wireless sensor network which helps in continuous and remote monitoring of the water quality data in India. The wireless sensor node in the system is designed for monitoring the pH(More)
Designing portable wireless devices for the continuous monitoring of EEG signals, in patients, requires attention to high precision, fast response times, extensive battery life, increased memory, and connectivity. These design factors have been confronted, solutions offered and a comprehensive, reliable and accurate system to wirelessly monitor EEG signals(More)
