How machine learning helped develop a new algorithm that could add life to bridges

A new algorithm developed by the University of Surrey could help structural engineers better monitor the health of bridges and alert them to when they need repair faster. Many authorities and organisations use structural health monitoring systems to keep track of the health of bridges, along with the weight of the traffic that it withstands on a day-to-day basis. This leads to a very high sampling rate of data, with some reaching at least 10 Hz and databases that have…

Researchers conduct first-ever combustion experiment with X-rays

Inside a gas turbine engine’s combustor, scientists use the world’s strongest X-ray source at the Advanced Photon Source at Argonne National Laboratory to peer inside formally unseen processes. Credit: U.S. Army photo by David McNally The U.S. Army Research Laboratory’s Center for Unmanned Aircraft Systems Propulsion made an historic first with its experiment in a gas turbine combustor using X-rays. The data will help advance gas turbine engine designs for higher power density and efficiency, scientists said. “This is the…

Technique strengthens buildings using wood waste

Credit: National University of Singapore Researchers from the National University of Singapore (NUS) have found an innovative and environmental-friendly technique to enhance building structures. The new method, which incorporates biochar recycled from saw dust into cement, improves the strength and water tightness of mortar and concrete, and offers an alternative use to the large volume of wood waste produced in Singapore. Wood waste from furniture factories makes up a huge portion of waste generated in Singapore. In 2016 alone, more…

UC students, faculty create innovative, internationally recognized technology for Boeing

Created as a collaboration between Boeing and UC students and faculty, Boeing Onboard is an interactive in-flight virtual assistant. This rendering shows what users would see using virtual reality glasses. Credit: Provided Air travel can be a pretty disconnected experience. Often times passengers are left without typical phone and internet capabilities and a limited choice in entertainment options to pass the time. Meanwhile, flight attendants are stretched too thin to cater to the needs of many travelers, from safety instructions…

the hack that allowed us to build Spectrum

Today we are introducing Spectrum: a new Cloudflare feature that brings DDoS protection, load balancing, and content acceleration to any TCP-based protocol. CC BY-SA 2.0 image by Staffan Vilcans Soon after we started building Spectrum, we hit a major technical obstacle: Spectrum requires us to accept connections on any valid TCP port, from 1 to 65535. On our Linux edge servers it’s impossible to “accept inbound connections on any port number”. This is not a Linux-specific limitation: it’s a characteristic…

Image: 3-D-molded interconnect devices

Credit: ESA/Art of Technology AG An alternative to conventional circuit boards, these ‘3-D-molded interconnect devices’ add electrical connectivity to the surface of three-dimensional structures. The aim is to combine mechanical, electronic and potentially optical functions in a single 3-D part, allowing the creation of intricate, precisely aligned designs using fewer parts while delivering significant savings in space and weight compared to conventional electronic manufacturing. “These prototype interconnect devices were produced using injection-moulded plastics incorporating electrical metallisation,” explains ESA’s Jussi…

Differentiable Plasticity: A New Method for Learning to Learn

By Thomas Miconi, Jeff Clune and Kenneth O. Stanley Neural networks, which underlie many of Uber’s machine learning systems, have proven highly successful in solving complex problems, including image recognition, language understanding, and game-playing. However, these networks are usually trained to a stopping point through gradient descent, which incrementally adjusts the connections of the network based on its performance over many trials. Once the training is complete, the network is fixed and the connections can no longer change; as a…

Researchers develop more comprehensive acoustic scene analysis method

Predictions of sounds were achieved by an improved method developed by an international team of researchers. Credit: IEEE/CAA Journal of Automatica Sinica Researchers have demonstrated an improved method for audio analysis machines to process our noisy world. Their approach hinges on the combination of scalograms and spectrograms—the visual representations of audio—as well as convolutional neural networks (CNNs), the learning tool machines use to better analyze visual images. In this case, the visual images are used to analyze audio to better…

Air Force looking to additive manufacturing to expand hypersonic flight capabilities

A sample of additively manufactured silicon oxycarbide (SiOC) material is tested at Arnold Air Force Base. The testing was conducted as part of a Cooperative Research and Development – Material Transfer Agreement between the Air Force Research Laboratory Aerospace Systems Directorate and HRL Laboratories. Credit: Air Force Office of Scientific Research The Air Force is testing materials produced through ceramic additive manufacturing to advance their potential future use in hypersonic flight vehicles. Scientists with the Air Force Research Laboratory Aerospace…

Transmitting measuring data wireless in real time

A sensor transfers the vibration spectra of the blisk via 5G with sub millisecond latency to a software. Credit: Fraunhofer IPT Sensors continuously record measurements in plant and machinery to check that everything is running according to plan and to enable any errors in the industrial production environment to be recognized at an early stage. However, as a rule, evaluation of the data is decentralized and takes place after a time lag. In contrast to this, the 5G wireless standard…
