Mistake in Yellow and Gray

Texas has always been a forward-looking state, where things are always going to get better and history doesn’t count for much.  The spirit of the state is well expressed by GM engineer and inventor Charles F. Kettering, who said in 1948, “My interest is in the future because I am going to spend the rest of my life there.”  So it’s natural to expect that this bias toward novelty would show up in architecture.  The problem with novelty in architecture…

Novel acoustics project aims to improve virtual reality, explore ear shape effects on 3-D sound

In the project, computer models…

Drone Deliveries to Hospitals in Rwanda » Curious Cat Science and Engineering Blog

Drone Deliveries to Hospitals in Rwanda Posted on June 25, 2017  Comments (0) Partnering with the Government of Rwanda, Zipline serves 21 hospitals nation-wide. They provide instant deliveries of lifesaving blood products for 8 million Rwandans. Their drones are tiny airplanes (instead of the more common tiny helicopter model). Supplies are delivered using parachute drops from the drone. Landings are similar to landings on aircraft carriers (they grab a line to help slow down the drone) and, in a difference…

China drone king turns to farming

Drone maker DJI was founded in 2006 in an apartment in Shenzhen by a young graduate with a passion for model planes and now makes almost two-thirds of the world’s civilian drones China drone-maker DJI is betting on flying machines that shoot pesticide instead of photos to fend off growing competition in the global remote-controlled aircraft market. The world leader in the civilian drones sector is switching its focus from leisure photography to more professional uses for its unmanned aerial…

Wearable technology could save lives and dollars in construction industry

At first glance, there’s nothing remarkable about SolePower’s latest work boot prototype. The Pittsburgh-based startup has gone through at least 20 other iterations of the boot, and this one took about six months to create. The footwear looks normal – all black save for the company’s white and green logo. But after a few steps, rectangular sections in the heels illuminate a bright orange, reminiscent of the lights inside a traffic tunnel. That’s when you know they’re charging. …

Drafting As An Art Of Technical Drawing

Drafting is also known as technical drawing, it is the method of creating drawing for architectures and engineering. A person who is skilled in this field is more popularly known as a draftsman. The fundamentals of drafting are easy. To be able to draft something, a draftsman places a piece of paper (or other drawing material) on any surface that has straight sides and right angle corners (drafting table). Another tool needed for drafting is a t-square. A t-square is…

Making ferromagnets stronger by adding non-magnetic elements — ScienceDaily

Researchers at the U.S. Department of Energy’s Ames Laboratory discovered that they could functionalize magnetic materials through a thoroughly unlikely method, by adding amounts of the virtually non-magnetic element scandium to a gadolinium-germanium alloy. It was so unlikely they called it a “counterintuitive experimental finding” in their published work on the research. “People don’t talk much about scandium when they are talking magnetism, because there has not been much reason to,” said Yaroslav Mudryk, an Associate Scientist at Ames Laboratory.…

iOS linting at Pinterest – Pinterest Engineering – Medium

Michael Schneider | Pinterest engineer, iOS Core Experience Coding consistency and guidelines are critical in a code base where a large group of developers work every day and new engineers join every week. In order to control code quality and enforce best practices, we recently added linting to our infrastructure to help developers write better code. Linting is the process of running a program that analyzes code for potential errors. At the same time, we were moving our current build…

Getting to Know Qingbo Hu

Prior to joining LinkedIn as a full-time employee, Qingbo completed an internship with us on the Analytics Data Mining team. He has also interned with Walmart’s e-commerce unit on the SEO team. He holds a Ph.D. in computer science from the University of Illinois at Chicago.   What are some of the coolest projects that you and your team have been working on?Among all the projects my team and I have worked on, I want to highlight three of them.…

Bioengineers create more durable, versatile wearable for diabetes monitoring

Researchers at the University of Texas at Dallas have developed a wearable diagnostic biosensor that can detect three interconnected, diabetes-related compounds — cortisol, glucose and interleukin-6 — in perspired sweat for up to a week without loss of signal integrity. The team envisions that their wearable devices will contain a small transceiver to send data to an application installed on a cellphone.
