Neighborhood Delivery Robots
The days of heading out to pick up food from a restaurant are coming to an end, at least in Washington, DC. A fleet of roughly 20 autonomous, knee-high neighborhood delivery robots recently appeared on the sidewalks of the nation’s capital. Their mission is to revolutionize hyper-local delivery in the big cities by bringing takeout […]
MRI With Proton Beam
MR guidance is emerging as a powerful tool for real-time monitoring of radiation treatments, offering excellent soft-tissue contrast and the ability to track intra-fractional tumor motion. Hybrid devices for MR-guided photon-based radiotherapy are now in clinical use. But to date, no such combined system exists for proton therapy.
Extraordinary Images Of The Lunar Eclipse
If you happened to look up into the sky on Sunday, January 20th, you probably spotted a ‘blood moon’, also known as a lunar eclipse. Millions of people around the world enjoyed the sight as the moon slowly turned dark, and then red over a period of several hours. However, a few extremely sharp-eyed viewers […]
Automation in Grocery Stores
The advent of online shopping ushered into homes across the globe, a revolution in convenience. No longer do consumers have to travel to a store to browse items and make a purchase. Instead, the store would come to them digitally with a click of a button. In the past two decades, the growth of on-line […]
Transmission Electron Microscope
TEM, or Transmission electron microscopy (also sometimes conventional transmission electron microscopy or CTEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample […]
Machine Vision In The Food And Beverage Industry
With high-precision imaging, the food processing and beverage industry tests even hard-to-inspect products with absolute reliability. The result: 100% quality and ever-growing productivity. The need to manufacture products reliably, and without faults is more important than ever in the food, beverage and packaging industries. The pressure to achieve this has led to extremely high levels […]
Gravitational Waves
The National Science Foundation’s LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational-wave detector have published new results from the first two observing runs. Four new black hole mergers have been announced. The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and […]
Railway Imaging Systems
Rail inspection is the practice of examining rail tracks for flaws that could lead to catastrophic failures. According to the United States Federal Railroad Administration Office of Safety Analysis, track defects are the second leading cause of accidents on railways in the United States.
Optical Coherence Tomography Angiography
A new kind of precise and non-invasive imaging called optical coherence tomography angiography (OCTA) has assisted much of the recent research on the eye’s connection with Alzheimer’s. It enables physicians to see the smallest veins in the back of the eye, including the red blood cells moving through the retina.
