New technology can clean water twice as fast as commercially available ultrafiltration membranes — ScienceDaily

More than one in 10 people in the world lack basic drinking water access, and by 2025, half of the world’s population will be living in water-stressed areas, which is why access to clean water is one of the National Academy of Engineering’s Grand Challenges. Engineers at Washington University in St. Louis have designed a novel membrane technology that purifies water while preventing biofouling, or buildup of bacteria and other harmful microorganisms that reduce the flow of water. And they…

Technique could yield insights into complex proteins involved in Alzheimer’s and other diseases — ScienceDaily

MIT researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer’s and other diseases. Using this new method, scientists should be able to analyze in mere minutes structures that would previously have taken years to decipher, says Robert Griffin, the Arthur Amos Noyes Professor of Chemistry. The new approach, which relies on short pulses of…

PCB Assembly Services – Screaming Circuits: No Open Vias in or near pads

The term “via” probably comes from the Latin word meaning “road.” Therefore, open via would essentially mean “open road.” Open roads, here in Oregon sometimes run through open range ranch land. That means that cows have as much right to be on the road as do cars. If you don’t want cows on your PC boards where the BGAs go, don’t leave open vias in your BGA footprint. Don’t do this: Here’s what happens: Your assembled board will likely be…

Empowering Data Science with Data Engineering Education

Data engineering education enables data scientists to better interface with engineering and ensures higher data quality. Authors: Michelle Du, Yu Guo, Jeff Feng Since launching Data University (Data U) at Airbnb two years ago, our data education program has made significant progress towards our overarching vision of empowering every employee to make data-informed decisions. To date, over 400 courses have been taught to thousands of course participants by the 55 volunteer faculty members from across the Data Science & Engineering organizations.…

Going global pays off big for Mizzou Engineering’s Garrow

Carly Garrow’s fellowship in Germany built her skills in a variety of areas and helped her land a job recently with medical device manufacturers Zimmer Biomet. Photo courtesy of Carly Garrow. Students have heard it many times — studying abroad will expand their horizons and provide them with global experience that employers desire. The reason they hear it so often is because it happens to be statistically true. For a more personal account, take Mizzou Engineering alumna Carly Garrow. Garrow, a…

My Ten-Character Win – Engineering Blog

Last year, Wealthfront changed the way we do business in a huge way. In order to better serve our clients by taking on more brokerage responsibilities ourselves, we transitioned from being a fully-disclosed brokerage to an omnibus brokerage. In addition to paving the way for new functionality such as our Portfolio Line of Credit, our clients have enjoyed more subtle improvements such as: deposits invested more quickly, account transfers processed more quickly and more visibly, and simpler monthly statements. For…

Mizzou Engineers head out on a different kind of winter break

Volunteering with adaptive ski programs that allow people with disabilities to experience skiing is just one example of how University of Missouri students serve the global community. This winter break, 475 Mizzou students will volunteer across the country and in the Dominican Republic. Photo courtesy of MU News Bureau. A total of 475 students took part in last week’s Mizzou Alternative Breaks, and among them were 24 Engineering students: Alexandra Crump, Liam Gray, Olivia LaVal, Margaret Page, Ethan Rackers, Jacquelyn Ware,…

Open-sourcing Spectrum 1.0.0 for mobile image uploads

DANIEL HUGENROTH As mobile camera hardware rapidly improves, our phones capture and store larger and larger files. Uploading these large files can eat up mobile data; it can take forever for them to load; and, sometimes, the files fail to load at all. To make the upload process more efficient, we developed Spectrum, an image processing library for Android and iOS. With Spectrum, we have improved the reliability and quality of image uploads at a large scale across our apps.…

Assistant dean, STEM colleagues land grant to study identity expression

Assistant Dean Tojan Rahhal, Terrell Morton of Education and Johannes Schul of Biology received an Inclusion, Diversity & Equity (IDE) Excellence Grant for Employees. Identifying and understanding contextual, cultural and developmental differences among identity expression for historically underrepresented students in science, technology, engineering and math (STEM) is key in supporting and growing these populations in STEM fields. Mizzou Engineering, through Assistant Dean for Inclusive Excellence and Strategic Initiatives Tojan Rahhal, is part of a project seeking to do just that…

Automating Datacenter Operations at Dropbox

  Introduction As a company that manages our own infrastructure we need to be able to rapidly install new server capacity and ensure that the equipment entering our production environment is highly reliable. Prior to the creation and implementation of the Pirlo system, engineering personnel at Dropbox manually intervened in most aspects of server/switch provisioning and validation. Pirlo was designed to eliminate and automate many of these manual processes. In this post we will describe Pirlo, a flexible system designed…
