Automated painting of individual pieces

Multi-physical simulation of a high-rotation atomizer with internal charging. In this example, the simulation is being used to calculate the drop trajectory on the car body of a Volvo V60. Credit: Fraunhofer FCC Reductions of 20 percent in paint use, 15 percent in energy consumption and 5 percent in production time – the SelfPaint automated painting system offers significant advantages compared to manual painting operations, which have previously been the preferred option. SelfPaint’s biggest advantage could well be that it…

Reliably determining and predicting attitude motion of defunct satellites

Fraunhofer FHR‘s space observation radar TIRA. Credit: Fraunhofer FHR Uncontrollable flying objects in the Earth’s orbit are an enormous risk for active satellites and for spacecraft in general. Since April 2012, the European environmental satellite ENVISAT has also been adrift in orbit. Now, the Fraun-hofer Institute for High Frequency Physics and Radar Techniques FHR has developed pioneering methods to precisely determine the attitude rotation of malfunctioning satellites and, thus, to support de-orbiting missions in the future. The ENVISAT environmental satellite…

Building Blockchain with Hyperledger : Developer’s Guide (Part 1)

In our previous post about blockchain, we described the basics and terminologies of blockchain technology and its success stories in various fields including supply chain management, prediction markets, identity management stock trading, governance, etc. As a quick recap of the blockchain, IBM is collaborating with other organizations with the aim of developing an open source implementation of the blockchain. The business use case is hosted by The Linux Foundation and is called the Hyperledger Fabric. Now that you are aware…

Biofeedback technology helping improve balance in Parkinson’s patients

Smarter Balance System. Credit: University of Houston University of Houston researchers in the Department of Health and Human Performance are helping patients with Parkinson’s disease regain stable balance and confidence in performing daily activities in their own homes. A research team is developing the Smarter Balance System (SBS), a smartphone-based biofeedback rehabilitation system that guides patients through a series of balance exercises using wearable technology. “Our overarching goal is to improve their quality of life by improving postural stability, reducing…

Artificial skin could allow robots to feel like we do

Researchers are running tests on pig skin to come up with an artificial alternative for robots. Credit: Dr Aisling Ni Annaidh at University College Dublin Artificial skin with post-human sensing capabilities, and a better understanding of skin tissue, could pave the way for robots that can feel, smart-transplants and even cyborgs. Few people would immediately recognise the skin as our bodies’ largest organ, but the adult human has on average two square metres of it. It’s also one of the…

3-D printing technologies transport students to ancient greece

The use of 3-D printing technologies in Victoria University of Wellington’s Classics Museum has students using ancient Greek artefacts the way they were intended—from interacting with 3-D printed ancient objects to designing their own amphorae (storage jars). Dr Diana Burton, senior lecturer in Victoria’s School of Art History, Classics and Religious Studies, wanted students to have practical experiences with the objects in the Museum without risking damage to the historic pieces. “In Greek art, pretty much everything is functional—they…

The Case Against Kotlin – Pinterest Engineering – Medium

Ryan Cooke | Android Engineer, Core Experience It’s a big decision to start using Kotlin in your app. Right now, Kotlin may be nearing the “Peak of Inflated Expectations” in the Hype Cycle. You can find endless quality blogs, podcasts and videos on the virtues of Kotlin. For this post let’s assume you understand the benefits of it. Here we’ll look in-depth at the challenges Android developers will likely face with Kotlin and offer solutions. There are real costs to…

Open Sourcing Jaqen, A Tool For Developing DNS Rebinding PoCs

Editor’s note: Members of the information security team at LinkedIn have an opportunity to work on research topics under a well-defined framework that allows them to evaluate new products and technologies, as well as explore the related threat surface. The team strives to find new and innovative ways to help simplify and strengthen security and contribute back to the community where possible to do so. In early 2017, Luke Young had the opportunity to make use of this framework and…

No one knew just how many Ubers and Lyfts were out there—until now

Northeastern researchers Alan Mislove and Christo Wilson created a program that works to determine the volume of drivers for these ride-hailing services in San Francisco, collecting data that are typically held closely by both companies. Credit: Northeastern University In urban areas—and in not so urban areas—around the globe, Uber and Lyft are ubiquitous. But knowing just how many are out there at a given time is a problem that’s eluded municipal transportation officials since the ride-hailing services burst onto the…
