Flood prediction model developed — ScienceDaily

The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Now an international team of researchers led by Nasser Najibi and Naresh Devineni at The City College of New York is offering a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding. Conceptualized by Najibi and tested on the Missouri River Basin, the statistical model is based on data in the area from…

The Moon, Mars, or Stay Home?

This coming Saturday marks the fiftieth anniversary of the first landing of humans on the moon.  I remember staying up late in my bathrobe and watching the blurry images on our old black-and-white tube-model TV as Neil Armstrong first set foot on the dusty surface.  I was no more moonstruck than most fifteen-year-olds were at the time.  I enjoyed the attention that engineers and high technology were getting as a part of the space program.  But the geopolitical forces that…

New Chemical Engineering Blog from A Chemical Engineer

This is a great blog in town discussing about chemical engineering. It is almost like this blog of mine. It is run by a chemical engineer, Mr. Barat, from India. His blog is continuously sharing about chemical industries, pharmaceuticals, refinery, power plant & offshore. It is an alternative learning platform for get lot of updated knowledge about chemical, mechanical, Instrumentation & HSE. Upon visiting this blog, I can clearly see 5 tabs on the top of the header, that shows…

Outcomes of non-operatively treated elbow ulnar in professional baseball players — ScienceDaily

Professional baseball players with a low-grade elbow injury that occurs on the humeral side of the elbow have a better chance of returning to throw and returning to play, and a lower risk of ulnar collateral ligament surgery than players who suffered more severe injuries on the ulnar side of the elbow. The research was presented at the Annual Meeting of the American Orthopedic Society of Sports Medicine. Led by Dr. AaKash Chauhan from DuPage Medical Group, Downers Grove, Ill.,…

Code Reviews at Medium – Medium Engineering

Small PRs, quick reviews, and working like we’re in this together Photo by Harley-Davidson on Unsplash Engineering teams have different norms and policies when it comes to code reviews. It can be frustrating to join a team and not know what is expected, or to operate with old assumptions and discover that they are at odds with a new team. In an effort to make it easier for engineers who come from companies with different practices, we wrote down some…

A new open source JavaScript engine optimized for mobile apps

Mobile applications are growing larger and more complex. Larger apps using JavaScript frameworks often experience performance issues as developers add features and complexity. These issues are generated from various spots, but the people using these apps expect them to run smoothly, regardless of the device they are on. To increase the performance of Facebook’s apps, we have teams that continuously improve our JavaScript code and platforms. As we analyzed performance data, we noticed that the JavaScript engine itself was a…

Creativity-based curriculum to build on initial success

Mizzou Engineering’s Heather K. Hunt and Ferris Pfeiffer, Theater’s Suzanne Burgoyne, and Education’s Johannes Strobel are the investigators on NSF-funded project “Creativity throughout the Curriculum: Educational Practices to Build the STEM Workforce of Tomorrow.” Actress Mary Lou Cook once said, “Creativity is inventing, experimenting, growing, taking risks, breaking rules, making mistakes, and having fun.” Innovation requires these things, but sometimes, the engineering curriculum focuses more on technical prowess and precision than on innovation;while not inherently negative, this focus can inhibit…

Carbon nanotube films enable method to recycle waste heat — ScienceDaily

The ever-more-humble carbon nanotube may be just the device to make solar panels — and anything else that loses energy through heat — far more efficient. Rice University scientists are designing arrays of aligned single-wall carbon nanotubes to channel mid-infrared radiation (aka heat) and greatly raise the efficiency of solar energy systems. Gururaj Naik and Junichiro Kono of Rice’s Brown School of Engineering introduced their technology in ACS Photonics. Their invention is a hyperbolic thermal emitter that can absorb intense…

Details of the Cloudflare outage on July 2, 2019

Almost nine years ago, Cloudflare was a tiny company and I was a customer not an employee. Cloudflare had launched a month earlier and one day alerting told me that my little site, jgc.org, didn’t seem to have working DNS any more. Cloudflare had pushed out a change to its use of Protocol Buffers and it had broken DNS. I wrote to Matthew Prince directly with an email titled “Where’s my dns?” and he replied with a long, detailed, technical…
