Sensing insole for footstrike pattern detection in runners

3-D design of the sensing insole (above) and the interface of the smartphone app. Credit: PolyU Researchers at The Hong Kong Polytechnic University (PolyU) have developed a mobile biofeedback device for footstrike pattern modification for injury prevention and rehabilitation in runners. The annual injury risk for regular runners is up to 80%. It is largely related to how runner‘s foot hits the ground. Emerging evidence suggests that heel or forefoot strike may result in injuries such as stress fractures or…

Exploring underground with a colliding drone

ESA, Natalino Russo www.natalinorusso.it ESA astronaut Luca Parmitano last weekend helped to explore the caverns under Sicily using a drone that deliberately bumped into its surroundings in order to build a map. ESA has been testing equipment, techniques and working methods for missions with astronauts in inner space for many years. Delving inside Earth and exploring caves often parallels the exploration of outer…

Join Us at the 10th Annual Hadoop Summit /…

We’re excited to co-host the 10th Annual Hadoop Summit, the leading conference for the Apache Hadoop community, taking place on June 13 – 15 at the San Jose Convention Center. In the last few years, the Hadoop Summit has expanded to cover all things data beyond just Apache Hadoop – such as data science, cloud and operations, IoT and applications – and has been aptly renamed the DataWorks Summit. The three-day program is bursting at the seams! Here are just…

Automation as a Service — Introducing Scriptflask – Netflix TechBlog – Medium

Authors : Fazal Allanabanda and Vilas Veeraraghavan Introduction Less than a year ago, we shared our testing wins and the challenges that lie ahead while testing High Impact Titles (HITs) globally. All this while ensuring the pace of innovation at Netflix does not slow down. Since then, we have made significant enhancements to our automation. So in this post, we wanted to talk about our evolution since last year. Our team’s focus still remains on providing test coverage to HITs globally…

A leap for 3-D printing

Credit: Matt Perko When the Space Shuttle hit the Earth’s atmosphere on its return trip from the cosmos, it was traveling at 17,000 miles per hour—25 times the speed of sound. Were it not for the protection of the ceramic tiles that acted as heat shields, the entire spacecraft would have burned to nothing. Talk about extreme conditions.…

Under the hood: Photo Search | Engineering Blog | Facebook Code

Today, the volume of photos taken by people with smartphone cameras challenges the limits of structured categorization. It is difficult for one person to categorize their own repository of smartphone photos, much less to define a structured taxonomy for everyone’s photos. On Facebook, people share billions of photos every day, making it challenging to scroll backward in time to find photos posted a few days ago, let alone months or years ago. To help people to find the photos they’re…

World’s first demonstration of multicolor 3-D in vivo imaging using ultra-compact Compton camera

The Compton camera only weighs 580g and is palm-sized, making it the world most compact medical gamma-ray detector. Credit: Waseda University As represented by conventional radiograph, radiological images provide only black and white figures in 2D space. The situation is basically the same for Single photon emission tomography (SPECT) and positron emission tomography (PET), which are the two most common molecular imaging techniques used in nuclear medicine. PET is used especially for early cancer and Alzheimer’s disease detection, but radioactive…

Engineering Ethics Blog: Your Money Or Your Data: The WannaCry Ransomware Attack

On May 12, thousands of users of Windows computers around the globe suddenly saw a red screen with a big padlock image and a headline that read, “Ooops, your files have been encrypted!”  It turned out to be a ransom note generated by an Internet worm called WannaCry.  The ransom demanded was comparatively small—about US $300—but the attack itself was not.  The most critical damage was caused in Great Britain where many National Health Service computers locked up, causing delays…

Smartwatches: Fading Fad or Must-Have Wearable Tech?

With the rise of Twitter’s instant trend-setting, real-time information broadcast platform, the necessity of a “right-now” information diet is highlighted by its user popularity and $2.5 billion global revenue. Consumers are no longer content to settle for next-day-information, and instead have pushed for access to a relentless 24/7 news cycle covering everything from foreign affairs to celebrity gossip. The trend which merges ease of access with availability has pushed the top tech development companies to tailor their products to satisfy…
