Implanted Connectors for Prosthetic Legs Outperform Common Sleeve Versions

This article appeared in Electronic Design and has been published here with permission. Electronics for “personal” medical devices is an area of great research interest, especially when the device can be shrunk down to a minuscule size and is easily wearable. Pursuing a well-traveled objective but with a different tactic, a team based at the Georgia Institute of Technology (Georgia Tech) has gone after the “mechanical” and vibrational signals from the heart and lungs rather than more-common electrocardiogram (EKG or…

Lifetime of Service – University of Missouri College of Engineering

Civil and Environmental Engineering Professor Glenn Washer Ultrasound. Ground penetrating radar. Thermal imaging. You probably don’t think of these Nondestructive Evaluation (NDE) technologies as necessary tools for bridge inspections. But Glenn Washer, professor of civil and environmental engineering, has conducted research that proves these technologies greatly enhance condition assessment of bridges, leading to improved inspections that help prevent accidents and collapses. In addition to teaching and researching NDE, Washer has given of his time as a volunteer to increase the…

DELF: Safeguarding deletion correctness – Facebook Engineering

What the research is: DELF is a new framework to help developers implement data deletion in modern applications. Traditional methods for implementing deletion require application developers to write repetitive, error-prone code. DELF’s main novelty lies in enabling developers to implement deletion in every product they build with minimal effort, which takes the form of annotations rather than code. DELF introduces multiple correctness validation techniques to help achieve semantic correctness and avoid mistakes that could potentially lead to retaining data that…

Indian eGov App-Store – Accelerating Delivery of e-Services for Citizens

The eGov app store is a repository of cloud-based applications to aid government agencies and departments in providing a common platform to host and run applications developed by government agencies and private players. This repository is a Pandora’s Box of reusable customizable and configurable applications, components, and web services developed as a NeGP (National e-Governance Plan) initiative. e-Gov App Store encourages start-ups and SME’s who develop government-centric applications. These applications are rigorously tested and after undergoing various trials and user…

World’s biggest container ships take shape in South Korea

At 400 metres (1,300 feet), the HMM St Petersburg is 100 metres longer than the Eiffel Tower is tall, and 62 metres wide On the bridge of one of the world’s biggest container ships, a worker in a grey protective suit installs the compass that will guide the leviathan across the world. The finishing touches are being put to the HMM St Petersburg at the Samsung Heavy Industries shipyard on the island of Geoje, at the southern tip of South…

Keep Kids Safe With FamiSafe Parental Control App

The Internet is as vast as the universe, but the only difference is, all aspects of the latter are not accessible by everyone, but the former is reachable to everyone and everything is open for access. This opens various doors of opportunity and information, but is all content on the internet safe? The concern lies for parents as they are not aware of what their inquisitive kids are browsing over the internet. But somehow, parents have to curb their anxiety…

Computational Causal Inference at Netflix | by Netflix Technology Blog | Aug, 2020

Jeffrey Wong, Colin McFarland Every Netflix data scientist, whether their background is from biology, psychology, physics, economics, math, statistics, or biostatistics, has made meaningful contributions to the way Netflix analyzes causal effects. Scientists from these fields have made many advancements in causal effects research in the past few decades, spanning instrumental variables, forest methods, heterogeneous effects, time-dynamic effects, quantile effects, and much more. These methods can provide rich information for decision making, such as in experimentation platforms (“XP”) or in…

How to Design a Low-Energy Power Supply for Automotive Apps

What you’ll learn The battery-drain risk of storing energy in batteries when a car is left stationary for a long time. How dc-dc buck converters can best serve switching regulators in terms of low quiescent current. A trio of energy-saving methods when using dc-dc converters. Automotive vehicles are becoming more sophisticated, integrating more advanced electronics to provide new comfort features in the car and increase safety for drivers and passengers. As automakers add more functionality and thus more electronics, the…

This article appeared in Microwaves & RF and has been published here with permission. The coronavirus pandemic of 2020 has changed the world in many ways, and one of the most remarkable transformations has been that of consumer retail. Market research from Kantar1 indicates that the number of consumers who did more than half of their shopping online in Europe’s three biggest e-commerce markets rose as much as 80% during the pandemic, and six in 10 respondents say they intend…

A New Real-Time Map-Matching Algorithm at Lyft | by Marie Douriez | Aug, 2020

By Marie Douriez, James Murphy, Kerrick Staley When you request a ride, Lyft tries to match you with the driver most suited for your route. To make a dispatch decision, we first need to ask: where are the drivers? Lyft uses GPS data from the drivers’ phones to answer this question. However, the GPS data that we get is often noisy and does not match the road. Location data is often noisy and does not match the road. To get…
