Optimum drill geometry for creating deep, narrow holes is determined using a computational model

Computational fluid dynamic simulations of a chip falling through a fluid enables optimization of gundrill design. Credit: A*STAR Singapore Institute of Manufacturing Technology Improving the design of drills capable of excavating deep holes should increase their performance and longevity. Scientists from A*STAR develop a computational model that can determine the ideal drill design, achieving significant savings. In designing a drill, a crucial consideration is the effective removal of material, known as chips. A standard drill bit, the part of the…

You’re amazing just the way you are – Wealthfront Engineering Blog

Abstraction is a technique for arranging computer systems in such a way as to reduce the complexity of interacting with them. The system makes a certain complexity level available for other systems to interact with, while suppressing some of the inner workings. Programming languages, for example, are abstractions over assembly languages, which are abstractions over machine-level languages. Efficient use of abstraction is essential to writing maintainable, extendable software. Identifying when to abstract or when to incorporate an existing abstraction requires…

Wearable device that tracks indoor and outdoor air quality

MIT-France student intern Annie Dai (seated) says of her summer at Plume Labs: “This was probably the best summer I’ve had in my life and I think that was partially because it’s the most responsibility I’ve been given on a project.” Credit: Lillie Paquette/School of Engineering This past June, Grace Li ’17 stepped off a plane in Paris ready to spend her summer tracking down a silent killer. Now Li, her former teammates, and the flock of trained pigeons who…

Drones controlled with brain-computer interface

Credit: Deanna Dent/ASU Now Single unmanned autonomous vehicles (UAVs) directed by joysticks, radio controllers, and mobile phones are already accomplishing a variety of useful tasks, such as aerial photography and security patrols. But using multiple drones requires multiple human operators, and this presents a coordination problem. Now a single operator using emerging…

Building a Network of Tunnels Underground to Ease the Flow of Traffic » Curious Cat Science and Engineering Blog

Building a Network of Tunnels Underground to Ease the Flow of Traffic Posted on October 1, 2017  Comments (0) “Roads must go 3D” – Elon Musk The Boring company plans to build the network of tunnels under the ground in order to combat traffic congestions all over United States. As seen in their presentation video, the idea is to construct a system of tunnels in which electric vehicles autonomously zip around cars, people and cargo transport in high speed under…

Run JavaScript Service Workers at the Edge

TL;DR: You’ll soon be able to deploy JavaScript to Cloudflare’s edge, written against an API similar to Service Workers. Try writing a Worker in the playground » Introduction Every technology, when sufficiently complicated, becomes programmable. You see this everywhere, but as a lifelong gamer, my personal favorite example is probably graphics cards. In the ’90s, graphics hardware generally provided a fixed set of functionality. The OpenGL standard specified that the geometry pipeline would project points from 3D space onto your…

Lighting a path to smarter homes, roads and bridges

If you’re worried about carbon monoxide poisoning, you might purchase a detector for your home. But what if your house itself could sense carbon monoxide and other potentially harmful gases – nitrogen oxides, natural gas, formaldehyde – without the need for a separate device for each chemical? And what if all these sensors spoke to each other through a single interface, a sort of super-thermostat? This vision could be realized one day using sensor technology currently being developed at…

Drones in disaster zones could prove a lifesaver

Credit: University of South Australia Pioneering research from the University of South Australia has shown for the first time that drones can be used to detect human vital signs in war zones and natural disasters. Under a collaborative agreement with the Defence Science and Technology (DST) Group, UniSA researchers have successfully trialled unmanned aerial vehicles to measure heart and respiratory rates using remote-sensing imaging systems, while hovering three metres from humans. Video footage from the drones can detect changes…

NASA tests first 3-D printed rocket engine part made with two different alloys

An image from a microscope reveals how the two metals, copper alloy and Inconel, mix and interlock to form a strong bond created by the innovative 3-D printing process during manufacturing of the igniter prototype. Credit: NASA/UAH/Judy Schneider Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, tested NASA’s first 3-D printed rocket engine prototype part made of two different metal alloys through an innovative advanced manufacturing process. NASA has been making and evaluating durable 3-D printed rocket parts…

Carmakers face billions in European CO2 fines from 2021: study

Bigger cars could mean bigger fines as automakers fail to meet new emissions standards Big-name carmakers including Volkswagen and Fiat Chrysler face fines running into the billions for failure to meet tough new European carbon dioxide emissions limits slated for 2021, a study has found. “Only four out of 11 carmakers are forecast to meet the EU 2021 CO2 emission target, with the rest facing significant fines,” researchers from British firm PA Consulting said in a statement Friday. European…
