Prana energy proliferated via gayatri meditation

‘Gaya’ means Prana or vital force and ‘Tri’ means to liberate. ‘Gayate pranaha iti gayatri’ which means that which liberates Prana is called Gayatri. Trana means to liberate or free. Prana is a bound conscious principle to the body, senses and their objects. By liberating Prana from this bondage one realizes one’s divine conscious state. In this manner the entire science of Prana dwells within Super Energy Gayatri. Previously those Extrasensory Potentials or ESP discussed can be attained via Gayatri…

JARVIS: Helping LinkedIn Navigate its Source Code

Relevance Relevance is a very important piece for any search system, and our codesearch is no exception. It is very important to show files at the top that users are most likely to open. Relevance for us involves assigning a score to every retrieved document, ranking them based on this score, and then returning the top K results. Score assignment is the most critical part for our relevance. We have multiple types of features, and the final score is a…

Self-powered paper-based ‘SPEDs’ may lead to new medical-diagnostic tools — ScienceDaily

A new medical-diagnostic device made out of paper detects biomarkers and identifies diseases by performing electrochemical analyses — powered only by the user’s touch — and reads out the color-coded test results, making it easy for non-experts to understand. “You could consider this a portable laboratory that is just completely made out of paper, is inexpensive and can be disposed of through incineration,” said Ramses V. Martinez, an assistant professor of industrial and biomedical engineering at Purdue University. “We hope…

Researchers devise app to protect PINs and passwords — ScienceDaily

Every ATM or smartphone user can attest to the discomfort of having a stranger standing close enough to observe a financial transaction — and potentially note a PIN or account number. Now researchers at the NYU Tandon School of Engineering have announced a first-of-its-kind application to combat such “shoulder-surfing,” whether in person or via a building’s video camera. Nasir Memon, NYU Tandon professor of computer science and engineering, explained that the technology, called “IllusionPIN,” deploys a hybrid-image keyboard that appears…

💚 → 👏 👏 👏 – Medium Engineering

A product engineering tale Back in the heady days of early July 2017, I was tasked with adapting the Medium 💚 system into something that allowed variable input. With the binary 💚 button, users could tell us when they liked a story, but we wanted to know how much they liked it, in comparison with other stories. In theory, this new data would allow us to surface truly good content over shiny clickbait. It was also the first piece of…

A disposable alcohol test reveals whether you are fit to drive within two minutes

The Finnish company Goodwiller has launched a rapid alcohol test it has developed in collaboration with VTT that measures the blood alcohol content from saliva. A disposable test fits easily into a small wallet and reveals the user’s fitness to drive within couple of minutes. Goodwiller Oy’s Promilless test was developed in cooperation with VTT Technical Research Centre of Finland. The test is based on the use of printed biochemical ingredients. “On the basis of a saliva sample, the…

Greening the concrete jungle—how to make environmentally friendly cement

With some tweaks to the recipe, cement and concrete can be made kinder to the planet. Credit: Postman Photos/Shutterstock.com Cement is the world’s most widely used material apart from water, largely because it is the key ingredient in concrete, the world’s favourite building material. But with cement’s success comes a huge amount of greenhouse emissions. For every tonne of cement produced in Australia, 0.82 tonnes of CO₂ is released. That might not sound like much, especially when compared with the…

Flaw detector for testing composite aircrafts

Thermal flaw prototype detector. Credit: Tomsk Polytechnic University A thermal flaw detector developed at Tomsk Polytechnic University will be used in the manufacturing of a new aircraft to replace the AN-2. The new model fully consists of composite materials and is developed by the Siberian Aeronautical Research Institute S. A. Chaplygin (SibNIA), Novosibirsk, Russia. The thermal flaw detector developed at TPU allows technicians to detect structural damage to aircraft both during manufacture and operation. The development involves an advanced set…

Magnetic Positioning Technology – How It Works

Indoor Positioning System (IPS) is a way to finding individuals or objects of interest inside a building utilizing radio signs, geomagnetic fields, inertial sensor information, barometric weight, camera information or other tangible data gathered by a cell phone gadget or tablet. Indoor positioning is playing a vital role in introducing the workplaces of the future and high-end connectivity and interactive work environment. They are utilized to distinguish and track a position. Simply consider, it works like a GPS, however for…
