• A coverage to allow using general-purpose manipulators in high-speed robotic air hockey

    Credit score: Liu et al. To carry out effectively on extremely dynamic duties, robots ought to be capable of transfer shortly and be extremely reactive. As robots sometimes have bodily constraints and {hardware} limitations, laptop scientists must also develop planners and trajectory optimization methods that may allow them to carry out speedy actions. One instance of a extremely dynamic process that robots may full is enjoying air hockey, a recreation through which gamers attempt to push a plastic disk into their opponent’s objective throughout a particularly designed desk. Whereas a number of roboticists have tried to coach robots to play air hockey previously, only some have tried to realize extremely…

  • Bending gentle for cheaper Web

    Credit score: Pixabay/CC0 Public Area Large space networks (WANs), the worldwide backbones and workhorses of at this time’s Web that join billions of computer systems over continents and oceans, are the inspiration of recent on-line companies. As COVID-19 has positioned a significant reliance on on-line companies, at this time’s networks are struggling to ship excessive bandwidth and availability imposed by rising workloads associated to machine studying, video calls, and well being care. To attach WANs over lots of of miles, fiber optic cables that transmit knowledge utilizing gentle are threaded all through our neighborhoods, made from extremely skinny strands of glass or plastic often called optical fibers. Whereas they’re extraordinarily…

  • New software may assist authors bust author’s block in novel-length works

    Of their method to forecast the longer term improvement of an ongoing written story, researchers first characterize the narrative world utilizing over 1,000 totally different “semantic frames,” the place every body represents a cluster of ideas and associated data. A predictive algorithm then seems on the previous story and predicts the semantic frames that may happen within the subsequent 10, 100, and even 1,000 sentences in an ongoing story.  Credit score: Pennsylvania State College Authors experiencing author’s block may quickly have a brand new means to assist develop the subsequent part of their story. Researchers on the Penn State School of Data Sciences and Expertise not too long ago launched…

  • New know-how may convey the quickest model of 5G to your own home and office

    UC San Diego electrical and pc engineering Ph.D. scholar Ish Jain poses with the brand new millimeter wave setup that he developed. The setup improves the throughput and reliability of millimeter wave indicators. Credit score: College of California – San Diego Shoppers of as we speak’s 5G cellphones could have skilled one of many following tradeoffs: spectacular obtain speeds with extraordinarily restricted and spotty protection, or widespread and dependable protection with speeds that are not a lot sooner than as we speak’s 4G networks. A brand new know-how developed by electrical engineers on the College of California San Diego combines the perfect of each worlds and will allow 5G connectivity…

  • A vision-based robotic system for 3D ultrasound imaging

    System workflow. (a) Three sorts of inputs from the depth digital camera (b) the sweep trajectory extraction module (c) the robotic motion module following a deliberate trajectory (d) the thing motion monitoring module. Credit score: Jiang et al. Ultrasound imaging strategies have proved to be extremely invaluable instruments for diagnosing a wide range of well being circumstances, together with peripheral artery illness (PAD). PAD, one of the frequent ailments among the many aged, entails the blocking or narrowing of peripheral blood vessels, which limits the availability of blood to particular areas of the physique. Ultrasound imaging strategies are among the many hottest technique of diagnosing PAD, resulting from their many…

  • OSU cryptography analysis results in large effectivity achieve in safe computing

    Credit score: Oregon State College Oregon State College researchers have developed a safe computation protocol that is 25% extra environment friendly than what had been thought the very best, which means future financial savings in time and vitality prices for teams needing to group up on computations whereas preserving their particular person information personal. Mike Rosulek, affiliate professor of laptop science within the OSU Faculty of Engineering, and graduate scholar Lance Roy offered their findings at this month’s digital forty first annual Worldwide Cryptology Convention, or Crytpo 2021. The convention is organized by the Worldwide Affiliation for Cryptologic Analysis. Roy, a 22-year-old who grew up in Corvallis, entered Oregon State’s…
