Fire kills nearly  3,700 Americans annually and destroys $23 billion in property , with many deaths occurring because traditional smoke detectors fail to alert occupants in time. Now, the NYU Fire Research Group at NYU Tandon School of Engineering has developed an artificial intelligence system that could significantly improve  fire safety  by detecting fires and smoke in  real-time  using ordinary security cameras already installed in many buildings. Published in the  IEEE Internet of Things , the  research  demonstrates a system that can analyze  video footage  and identify fires within 0.016 seconds per frame—faster than the blink of an eye—potentially providing crucial extra minutes for evacuation and  emergency response . Unlike conventional smoke detectors that require significant smoke buildup and proximity to activate, this AI system can spot fires in their earliest stages from video alone. "The key advantage is speed and co...

  Actually helps to store electricity at different terrains to setup the whole city grids been connected and infact help for solar panels houses as well as in the mountain regions where it generally can't able to generate the electricity grid as not every mountains means they have dam too to fulfill the energy requirement of that house easily. Imagine a house that doesn't just shelter you but also stores electricity. It may sound like science fiction, but it's now closer to reality than ever before. A research team at Aarhus University has demonstrated how the world's most widely used building material can be transformed into a living energy device. By embedding energy-producing bacteria in cement, they have created a biohybrid supercapacitor with surprisingly high performance and a remarkable ability to regenerate itself over time. "We've combined structure with function," says lead researcher Qi Luo. "The result is a new kind of material that can bo...

  Whether you're an artist, advertising specialist, or just looking to spruce up your home, turning everyday objects into dynamic displays is a great way to make them more visually engaging. For example, you could turn a kids' book into a handheld cartoon of sorts, making the reading experience more immersive and memorable for a child. But now, thanks to MIT researchers, it's also possible to make dynamic displays without using electronics, using barrier-grid animations (or scanimations), which use printed materials instead. This visual trick involves sliding a patterned sheet across an image to create the illusion of a moving image. The secret of barrier-grid animations lies in its name: An overlay called a barrier (or grid) often resembling a picket fence moves across, rotates around, or tilts toward an image to reveal frames in an animated sequence. That underlying picture is a combination of each still, sliced and interwoven to present a different snapshot depending on ...

Professionals in agriculture, defense and security, environmental monitoring, food quality analysis, industrial quality control, and medical diagnostics could benefit from a patent-pending innovation that opens new possibilities of conventional photography for optical spectroscopy and hyperspectral imaging. Young Kim, Purdue University professor, University Faculty Scholar and Showalter Faculty Scholar, and postdoctoral research associate Semin Kwon of the Weldon School of Biomedical Engineering created an algorithm that recovers detailed spectral information from photographs taken by conventional cameras. The research combines computer vision, color science and optical spectroscopy. "A photograph is more than just an image; it contains abundant hyperspectral information," Kim said. "We are one of the pioneering research groups to integrate computational spectrometry and spectroscopic analyses for biomedical and other applications." A paper about the team's rese...

Artists are always looking for new ways to create and express themselves. A growing trend is the use of multiple layers of see-through materials, such as Plexiglas, to create paintings that have real depth, transforming two-dimensional images into three-dimensional illusions that feel more realistic and lifelike. But can these layered works be made even more immersive? A new study, published in  Royal Society Open Science , answers this question by demonstrating a novel process to transform a multilayer acrylic painting into a full-color, three-dimensional hologram. In addition to offering a striking way to experience art, this technique provides a novel method for preserving and reproducing valuable works. The researchers used a painting of a tiger titled "Taxonomy Test 1" by renowned Colombian artist Yosman Botero. He created the  artwork  by painting in acrylic on nine transparent layers of Plexiglas. To begin the process, the research team digitized the artw...

Translating electrochemical performance of large format batteries to microscale power sources has been a long-standing technological challenge, limiting the ability of batteries to power microdevices, microrobots and implantable medical devices. University of Illinois Urbana-Champaign researchers have created a high-voltage microbattery (> 9 V), with high-energy and -power density, unparalleled by any existing battery design.  Join our   whatsapp group for latest articles updates. Material Science and Engineering Professor Paul Braun (Grainger Distinguished Chair in Engineering, Materials Research Laboratory Director), Dr. Sungbong Kim (Postdoc, MatSE, current assistant professor at Korea Military Academy, co-first author), and Arghya Patra (Graduate Student, MatSE, MRL, co-first author) recently published their paper "Serially integrated ...

In the future, the energy needed to run the powerful computers on board a global fleet of autonomous vehicles could generate as many greenhouse gas emissions as all the data centers in the world today.  Join our   whatsapp group for latest articles updates. That is one key finding of a new study from MIT researchers that explored the potential energy consumption and related carbon emissions if autonomous vehicles are widely adopted. The data centers that house the physical computing infrastructure used for running applications are widely known for their large carbon footprint: They currently account for about 0.3 percent of global greenhouse gas emissions, or about as much carbon as the country of Argentina produces annually, according to the International Energy Agency. Realizing that less attention has been paid to the potential footprint of ...
