IMSE spreads knowledge through two seminar series

The MU IMSE team listens to a presentation from the team at Missouri-St. Louis. The Industrial and Manufacturing Systems Engineering Department kicked off two different seminar series this fall, with the goal of repeating them each semester. Mizzou IMSE began a three-part eLogistics seminar with Missouri-St. Louis and the University of Western Cape in South Africa, and this series will conclude with a presentation by UWC on Nov. 29. In addition, the Mizzou Center for Excellence in Logistics and Distribution…

The new face of South American people — ScienceDaily

The history of the peopling of the Americas has just been interpreted afresh. The largest and most comprehensive study ever conducted on the basis of fossil DNA extracted from ancient human remains found on the continent has confirmed the existence of a single ancestral population for all Amerindian ethnic groups, past and present. Over 17,000 years ago this original contingent crossed the Bering Strait from Siberia to Alaska and began peopling the New World. Fossil DNA shows an affinity between…

Cross shard transactions at 10 million requests per second

Dropbox stores petabytes of metadata to support user-facing features and to power our production infrastructure. The primary system we use to store this metadata is named Edgestore and is described in a previous blog post, (Re)Introducing Edgestore. In simple terms, Edgestore is a service and abstraction over thousands of MySQL nodes that provides users with strongly consistent, transactional reads and writes at low latency. Edgestore hides details of physical sharding from the application layer to allow developers to scale out…

Architecting Uber’s New Driver App in RIBs

By Yohan Hartanto and Sami Aref This article is the second in a series covering how Uber’s mobile engineering team developed the newest version of our driver app, codenamed Carbon, a core component of our ridesharing business. Among other new features, the app lets our population of over three million driver-partners find fares, get directions, and track their earnings. We began designing the new app in conjunction with feedback from our driver-partners in 2017 and began rolling it out for…

Student team streamlines MU Engineering staff workflow

A team of students created coerequest.missouri.edu for submitting tickets for fiscal, human resources and marketing or communication tasks. In October, MU introduced the College of Engineering’s new administrative work request site – a project largely spearheaded and implemented by a team of students. The core developing group — Yongfang Qing, Joshua Thompson, Han Song, Mason Breece, Benjarit Hotrabhavananda, and Huiming Sun, as well as their supervising faculty Dong Xu and Nick Wergeles of the IT Department — created coerequest.missouri.edu for…

Cloud Computing without Containers

Cloudflare has a cloud computing platform called Workers. Unlike essentially every other cloud computing platform I know of, it doesn’t use containers or virtual machines. We believe that is the future of Serverless and cloud computing in general, and I’ll try to convince you why. Isolates Two years ago we had a problem. We were limited in how many features and options we could build in-house, we needed a way for customers to be able to build for themselves. We…

Laser system prevents contamination on aircraft surfaces

Credit: Wararat Sukharom, Shutterstock Scientists have developed a laser material processing method to produce textured surfaces that repel dirt and water. This technology will primarily be used in the aerospace industry. The use of coatings that mimic the lotus plant, whose leaves have self-cleaning properties, is becoming more common in a broad range of applications, from industry to medicine. When water falls on these leaves, it forms beads that roll off, taking dust and dirt with them thanks to the…

Aerospace detection technology designed to prevent catastrophic events in energy and extreme environments

New Purdue University aerospace detection technology uses advanced sensors, along with data science and machine learning elements, to detect and predict failures within certain materials. Credit: Vikas Tomar Could new technology from Purdue University researchers have helped save the Titanic? Engineers from Purdue have developed technology to help prevent catastrophic failures involving nuclear, energy and other materials in extreme environments. “Our advancements in temperature measuring and stress sensing can potentially save lives and significantly reduce costs,” said Vikas Tomar, a…

A toast to the proteins in dinosaur bones — ScienceDaily

Burnt toast and dinosaur bones have a common trait, according to a new, Yale-led study. They both contain chemicals that, under the right conditions, transform original proteins into something new. It’s a process that may help researchers understand how soft-tissue cells inside dinosaur bones can survive for hundreds of millions of years. A research team from Yale, the American Museum of Natural History, the University of Brussels, and the University of Bonn announced the discovery Nov. 9 in the journal…

China steps up drone race with stealth aircraft

China’s drones are now flying in the Middle East, as Beijing is more willing than the United States to sell its military UAVs to other nations.  China is unleashing stealth drones and pilotless aircraft fitted with AK-47 rifles onto world markets, racing to catch up to US technology and adding to a fleet that has already seen combat action in the Middle East. Combat drones were among the jet fighters, missiles and other military hardware shown off this week at…
