What is Gen-Z? An Overview of Gen-Z Memory-Semantic Fabric Architecture

Network interface cards (NICs) have been on the market since shortly after the first PCs in the mid-1980s. However, over the past few years, we’ve seen the emergence of SmartNICs. Each company in this market has a different definition of the SmartNIC product segment. The most basic definition is as simple as a NIC that’s programmable. Conversely, others have overloaded the concept by heaping vast amounts of silicon and firmware into their implementations. At the end of the day, though,…

Energy Storage Systems Boost EV Fast-Charger Infrastructure (Part 2)

Part 1 discussed the role of energy storage systems (ESS) in dc fast-charging systems and defined the critical components of the charging station—the sources, the loads, the energy buffer. Now, as discussed in this article, an analysis must be done for the four power–conversion systems that create the energy paths in the station. The four power-conversion systems are all sitting on the main dc bus, rated 1000 to 1500 V dc. The higher the required power, the higher the dc…

There’s an App for That: Bosch Rexroth Reveals Web-Based Automation Platform

FDT Group, an independent not-for-profit industry association that supports the evolution of FDT technology, released its platform-independent FDT 3.0 – FDT IIoT Server (FITS) standard, built to empower digital transformational benefits for the automation supplier and end-user communities in the process, hybrid and discrete markets. The association also released FDT 3.0 Developer Toolkits to help the vendor community begin development efforts with a modern Integrated Development Environment (IDE) to easily create and customize next-generation, cross-platform FDT 3.0 solutions. The new…

Giraldo-Londoño Named Inaugural James W. and Joan M. O’Neill Faculty Scholar in Engineering

Oliver Giraldo-Londoño currently is a PhD candidate at the Georgia Institute of Technology. Oliver Giraldo-Londoño has been selected as the College of Engineering’s inaugural James W. and Joan M. O’Neill Faculty Scholar in Engineering. Giraldo-Londoño currently is a PhD candidate at the Georgia Institute of Technology and expects to complete his degree this fall. He received a bachelor’s in civil engineering in 2010 from Universidad Nacional de Colombia, Sede Medellin, and his master’s in structural engineering in 2014 from Ohio…

Eco-preneurs Use Renewable Energy to Rebuild Our Planet’s Reefs

Can technology help reverse the loss of coral reefs occurring across the planet? Initial trials of a system for restoring coral reefs show that it’s possible and practical to use renewable energy to draw minerals from the ocean itself to create structures that become homes for reef-building organisms. The accelerated process, developed by CCell Renewables, a marine engineering company, has demonstrated the ability to create healthy, living reefs at an accelerated rate in 500 small-scale trials conducted throughout the world. …

NASA astronauts launch from America in historic test flight of SpaceX Crew Dragon — ScienceDaily

For the first time in history, NASA astronauts have launched from American soil in a commercially built and operated American crew spacecraft on its way to the International Space Station. The SpaceX Crew Dragon spacecraft carrying NASA astronauts Robert Behnken and Douglas Hurley lifted off at 3:22 p.m. EDT Saturday on the company’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. “Today a new era in human spaceflight begins as we once again launched…

The “Weight” is Over for Lightweight 3D-Printed Parts

Many Americans can relate to the weight challenge that faced Branch Technology in a project at Field Museum in Chicago. Instead of shedding a few extra pounds after the holidays, the 3D printing company worked with engineers from Chicago Flyhouse to face a task that involved safely supporting approximately 28 tons in a facility that attracts more than 1.65 million visitors annually. Branch Technology’s solution involved the use of its patented additive manufacturing process to create unique architectural products. Chicago…

Meta-Graph: Few-Shot Link Prediction Using Meta-Learning

This article is based on the paper “Meta-Graph: Few Shot Link Prediction via Meta Learning” by Joey Bose, Ankit Jain, Piero Molino, and William L. Hamilton Many real-world data sets are structured as graphs, and as such, machine learning on graphs has been an active area of research in the academic community for many years. One popular machine learning task on graphs is link prediction, which involves the prediction of missing relationships/edges between the nodes in the graph. For instance,…

Spotify Modernizes Client-Side Architecture to Accelerate Service on All Devices

Engineer Carl Engström explains how lifting the 10,000 limit on Liked Songs enabled his team to address a much deeper issue and improve the listening experience of end users, whatever their device or network.    At first glance, lifting the 10,000 limit on Liked Songs seems like a simple engineering exercise. Some Reddit commentators even claimed to have identified a few lines of code that set the restriction. Why not just delete them and tidy up any gaps? As the…
