A simple way to turn 2D drawings into 3D objects

Demonstration of an ‘impossible bottle’ construction. Drawing on thin and flexible film enables on site reconfiguration of a 3D architecture inside a narrow space that would be inaccessible to conventional 3D pr inters. Credit: Song et al., Sci. Adv. 2021; 7: eabf3804 A team of researchers affiliated with several institutions in South Korea has developed a simple method for converting 2D drawings to 3D objects. In their paper published in the journal Science Advances, the group describes their technique and…

Digitalized road construction uses no concrete

The robotic arm lays out the “knitting pattern.” Empa researchers are investigating different patterns in a number of test series. Credit: Empa A robotic arm lays out a string in a mandala-like pattern on a bed of gravel. What appears to be a contemporary art performance is basic research that explores new ways in road construction. On the one hand, robot-assisted construction techniques for road building are being tested that have so far only been used in structural engineering. On…

New device security partnerships for Cloudflare One

Last October, we announced Cloudflare One, our comprehensive, cloud-based network-as-a-service solution that is secure, fast, reliable, and defines the future of the corporate network. Cloudflare One consists of two components: network services like Magic WAN and Magic Transit that protect data centers and branch offices and connect them to the Internet, and Cloudflare for Teams, which secures corporate applications, devices, and employees working on the Internet. Today, we are excited to announce new integrations with VMware Carbon Black, CrowdStrike, and…

Steel Bridge Team Prepares for Competition

Members of the 2021 Steel Bridge Team. From left to right: Kenyon Shutt, Edgar Pithua, Corey Valleroy, Olivia Bommelje, Madeline Hartranft, Blake Peters. When he was a first-year student, Corey Valleroy went to the College’s New Student BBQ to learn about the various student organizations within Mizzou Engineering. He wanted to get involved and contribute to a club immediately, and he found that opportunity through the Steel Bridge Team. “They stated they were a smaller club and said ‘We really…

These examples show the way

Understanding urban flooding requires us to contend with the underlying natural systems over which we have built our cities and towns. Credit: Bianca De Marchi business-as-usual planning principles—especially as these disasters tend to disproportionately affect disadvantaged populations, increasing inequality in Australia. We need to design our urban spaces around the idea that flooding is inevitable. That means not building on flood plains, and thinking creatively about what can be done to create urban “sinks” to hold water when floods strike.…

Announcing Network On-ramp Partners for Cloudflare One

Today, we’re excited to announce our newest Network On-ramp Partnerships for Cloudflare One. Cloudflare One is designed to help customers achieve a secure and optimized global network. We know the promise of replacing MPLS links with a global, secure, performant and observable network is going to transform the corporate network. To realize this vision, we’re launching partnerships so customers can connect to Cloudflare’s global network from their existing trusted WAN & SD-WAN appliances and privately interconnect via the data centers…

Moving k8s communication to gRPC

Over the past year and a half, Cloudflare has been hard at work moving our back-end services running in our non-edge locations from bare metal solutions and Mesos Marathon to a more unified approach using Kubernetes(K8s). We chose Kubernetes because it allowed us to split up our monolithic application into many different microservices with granular control of communication. For example, a ReplicaSet in Kubernetes can provide high availability by ensuring that the correct number of pods are always available. A…

Reviewing recent advancements in the development of solid-state batteries

Cost and design considerations towards a Li metal-based SSB. A) Typical architecture of a Li metal-based SSB. B) Estimated cost projection for an SSB to be competitive with an LIB based on LLZO estimations and material costs. Processing costs are not applicable in ‘current status’, given that there is no production at the moment. A 20 µm fully dense LLZO solid electrolyte (SE) has been considered to estimate current materials costs in US$ m−2 . a) The estimated solid-electrolyte production costs for…

First images of the cosmic web reveal a myriad of unsuspected dwarf galaxies — ScienceDaily

Although the filaments of gas in which galaxies are born have long been predicted by cosmological models, we have so far had no real images of such objects. Now for the first time, several filaments of the ‘cosmic web’ have been directly observed using the MUSE (1) instrument installed on ESO’s Very Large Telescope in Chile. These observations of the early Universe, 1 to 2 billion years after the Big Bang, point to the existence of a multitude of hitherto…

Engineers improve the technology of high-performance concrete casting in winter

At low temperatures, concrete tends to set unevenly which can lead to a collapse. A team of engineers from RUDN University suggested using infrared light and adding silicon and ash to concrete to solve this issue.
