How Hybrid Approach Can Enhance Quality Of Ultrasonic Images
Ultrasonic imaging is simple and cost-effective, especially for use in remote places, but it is not as good as CT or MRI imaging. However, with each passing day, and with technology getting better and better, software-based ultrasonic imaging systems are becoming better too. It is just a matter of time before these start replacing CT and MRI, according to the authors

Design Your Own Digital Photo Frame
This digital photo frame is designed using Arduino Uno. Smartphones with high-resolution cameras and enhanced features have motivated people to click photos of almost everything that they come across. It is not possible to frame all photos on a wall and, hence, the digital photo frame was invented in the 1990s, which would accept memory cards directly from digital cameras and display photos on the screen

Indigenous Robotic Solutions For Underwater Inspection
Without proper care and maintenance, decades old infrastructure is often subject to catastrophic failures, causing loss of life and property. This makes it necessary to regularly assess and monitor assets, which is a complicated task especially for subsea structures like dams, bridges, ships, oil and gas platforms. This led to the foundation of IIT-Madras incubated startup Planys Technologies in 2015 with an aim to develop customisable robotic inspection and survey solutions for both onshore and offshore submerged structures

Robotic Inspection To Fight Waste-Water Crisis
Only twenty per cent of the water supplied in urban areas is used for drinking and cooking, the rest is used for bathing, washing, toilets, sinks, etc. Seventy to eighty percent of the water that is not used for drinking or cooking gets stuck in leaking and broken sewage pipelines, resulting in contamination of the ground water. Only the remaining twenty to thirty per cent of the waste water reaches a sewage treatment plant
