Scientists develop artificial intelligence system for high precision recognition of hand gestures

(Left to Right) Members of the NTU study include research fellow Pan Shaowu, Professor Chen Xiaodong, Director of the Innovative Centre for Flexible Devices (iFLEX) and first author Wang Ming from the School of Materials Science & Engineering. Credit: NTU Singapore Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed an Artificial Intelligence (AI) system that recognizes hand gestures by combining skin-like electronics with computer vision. The recognition of human hand gestures by AI systems has been a valuable…

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…

Theory vs. Practice: Learnings from a recent Hadoop incident

Our disaster recovery strategy has largely been focused around replicating data from a cluster in the event of data loss in another. Let’s compare how this practice held up with theory under the cloud of a real and significant incident. Large consequences of small lossesCompared to the loss of machines that was inadvertently spread across a handful of racks, the data loss was relatively small (~0.02%). However, we knew this would result in permanent data loss for the (HDFS) blocks…

Maximize Thermal Performance in Automotive DC-DC Converters

Download this article in PDF format. A dc-dc converter is an electric circuit that converts a source of direct current (dc) from one voltage level to another by storing the input energy temporarily and then releasing that energy to the output at a different voltage. Converters protect electronic devices from power sources that are too strong or step up the level of the system input power to ensure it runs properly. The push to higher power density and the necessity…

Just-Launched Mars Rover Will Test Spacesuit Materials

At a Glance: Eliminating the cobalt—the “blood diamond of batteries”—from Li-ion batteries could bring down production costs. Researchers at Texas A&M University are developing materials that prevent lithium-ion batteries from heating and failing. Recalls of millions of devices have been linked to materials used in lithium-ion batteries. The global recall of the Samsung Galaxy Note7 due to battery malfunction (i.e., blowing up) is behind us, but the fiasco’s damaging effects remain in the collective memory of component manufacturers. That the…

In a Sea of Change, Engineers Retain Cautious Optimism

Making all-electric, mobile, off-highway equipment viable is a complicated engineering proposition. One of the key building blocks of such an approach is devising a way to recharge the vehicles’ batteries. Using a diesel generator doesn’t make sense when one of the overarching goals of the all-electric concept is to come up with a greener approach with a minimal carbon footprint. When our company Envision Solar decided to tackle the challenge, building what we called the Electric Vehicle Autonomous Renewable Charger…

Unbundling Data Science Workflows with Metaflow and AWS Step Functions | by Netflix Technology Blog | Jul, 2020

by David Berg, Ravi Kiran Chirravuri, Romain Cledat, Jason Ge, Savin Goyal, Ferras Hamad, Ville Tuulos tl;dr Today, we are releasing a new job scheduler integration with AWS Step Functions. This integration allows the users of Metaflow to schedule their production workflows using a highly available, scalable, maintenance-free service, without any changes in their existing Metaflow code. The idea of abstraction layers is a fundamental way to manage complexity in computing: Atoms make transistors, transistors make functional units in CPUs,…

Polyurethane: A New Solution for Data Center Wiring

At a Glance: As communication systems have improved and expanded in the age of IoT, the need for data security has increased. The MQTT protocol can provide efficient and secure integrating industrial automation with the cloud using IIoT principles. MQTT protocols also can help end-users achieve a more consumer look and feel to applications while maintaining the robustness needed in industrial settings. Internet of Things (IoT) devices and apps are providing consumers with improved access to and control of their…

DeText: A deep NLP framework for intelligent text understanding

Our logo is inspired by the sloth: Relax like a sloth, and let DeText do the understanding for you DeText is analogous to the accessories and attachments that come with power tools, such as a cordless drill. While the drill’s “engine” may be inherently powerful, it is important to use the right attachment to achieve your desired result.  Similarly, with DeText, users can swap NLP models depending on the type of task and leverage the models to make search and…

Computer Science Alumnus Named VP of Engineering

Sudheer Koganti Students often hear college prepares them for jobs that don’t exist yet. Sudheer Koganti is proof. He is the new Vice President of Engineering at ImageWare® Systems. There, he leads multiple engineering teams that develop biometric multi-factor authentication and identity the software it incorporates allowing you to unlock your phone with your face. Such technology wasn’t around when Koganti earned his master’s in computer science at Mizzou in the 1990s. But the knowledge he gained through the program…
