Pressure sensor can identify early stages of flat feet

It records the data from mobile sensors placed on an insole of a shoe. Later, it is being sent via Bluetooth connection to a computer for visualization. Credit: KTU A team of researchers at Kaunas University of Technology (KTU) have designed a device for measuring pressure on human feet. Its applications include pediatric illnesses and monitoring the physical condition of professional athletes. The most mechanical pressure is endured by the feet, which bear all of a person’s weight while walking.…

Mizzou summer program gives KAU students real-world experience

An international program offering hands-on, interdisciplinary projects that prepare students for real-world issues facing engineers in their home country is sure to attract high-quality attendees. And when it offers exposure to new cultures and novel educational methods, it attracts the best and brightest. In its fourth year, the University of Missouri’s King Abdulaziz University Internship for Engineering students has the formula down pat. The six week-long internship saw 24 students from King Abdulaziz University (KAU) in Jeddah, Saudi Arabia, come…

Somersaulting simulation for jumping bots

A simulation (top row) and real-world experiment (bottom row) match for the same jumping mechanism designed to flip over a wall and land right side up on the other side. This simulation was generated by a new method that accurately predicts the real-world behavior of such mechanisms undergoing large-deformations, high-speed dynamics, frictional contact and impact. It does so at speeds fast enough to now be used in automated design algorithms that must rapidly, yet accurately, predict whether a design will…

Screaming Circuits: Eclipse-o-pocalypse 2017

Save the date: August 21, 2017. I don’t need to tell you what’s happening that day, but I will anyway. It’s total eclipse day here in the USA. I wouldn’t care too much, except a) I think total eclipses are cool, b) the last one I experienced involved watching the rain clouds get dark and then get light again, and c) most important – we, at Screaming Circuits, are sitting right on the edge of totality. Canby, Oregon, where we…

Is it Alzheimer’s disease or another dementia? New, noninvasive method may help with diagnosis — ScienceDaily

A new method may help determine whether a person has Alzheimer’s disease or frontotemporal dementia, two different types of dementia that often have similar symptoms, according to a preliminary study published in the July 26, 2017, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Making the correct diagnosis can be difficult,” said study author Barbara Borroni, MD, of the University of Brescia in Brescia, Italy. “Current methods can be expensive brain scans or invasive lumbar…

Incorporating AI into a computer-based rendering system — ScienceDaily

Modern films and TV shows are filled with spectacular computer-generated sequences computed by rendering systems that simulate the flow of light in a three-dimensional scene and convert the information into a two-dimensional image. But computing the thousands of light rays (per frame) to achieve accurate color, shadows, reflectivity and other light-based characteristics is a labor-intensive, time-consuming and expensive undertaking. An alternative is to render the images using only a few light rays. That saves time and labor but results in…

Powering Helix’s Auto Rebalancer with Topology-Aware Partition Placement

Partition assignments are critical to a typical distributed data system. A partition’s replicas could be in different states. For example, in the above graph, each partition has three replicas; one of them is the Primary replica, while the other two are Backup replicas.   Apache Helix is a generic cluster management framework used for the automatic management of partitioned and replicated distributed systems hosted on a cluster of nodes. Helix automates the reassignment of partitions in the face of node…

Improve Your Communication using WiFi Calling

With so many features on our smartphones, we often forget what these devices were originally intended to do — make calls. Of course, as much time as we spend taking photos, browsing social media, shopping, and playing games on our phones, we still expect to be able to make calls without any problems. Although rare, many items can interfere with the features on any phone, no matter what network you are using. Find out how Wi-Fi calling can help improve…

Using AI for new visual storytelling techniques in VR | Engineering Blog | Facebook Code

Artificial intelligence is becoming an increasingly important tool within the artistic community to foster visual creativity. Two frequently used techniques are generative adversarial networks (GANs), which can generate visually realistic images, and style transfer, which can turn photos or videos into works of art by applying the artistic qualities of one image style — such as a painting — to other images and videos. At Facebook AI Research (FAIR), we wanted to investigate further how artists and professionals typically trained…

Chaos Automation Platform – Netflix TechBlog – Medium

We are excited to announce ChAP, the newest member of our chaos tooling family! Chaos Monkey and Chaos Kong ensure our resilience to instance and regional failures, but threats to availability can also come from disruptions at the microservice level. FIT was built to inject microservice-level failure in production, and ChAP was built to overcome the limitations of FIT so we can increase the safety, cadence, and breadth of experimentation. At a high level, the platform interrogates the deployment pipeline…
