Mizzou Engineer discovers new method to measure workplace stress

Participants were required to complete process monitoring and Multi-Attribute Task Battery tasks together. Essentially, they worked as control room operators in an oil and gas refinery plant, monitoring gauges, responding to alerts, tracking information on computer screens and more. Photo by Ryan Owens. Measuring the workload for individuals doing individual tasks is becoming fairly simple. Researchers measure the time each task takes and how much time it takes up during a worker’s given day. But what about the workload of…

Screaming Circuits: The Social Media Net

I kind of like the phrase “the social media net.” I doubt that I actually coined it, but I can’t think of exactly where I may have first heard it. Regardless, a net is one of the things that comes to mind when I think of social media marketing – a “fishing” net, not an “Inter” net. As I’ve said many times before (I do understand that I may not have said it to you, but I have said it…

AI at Uber is a rapidly growing area across both research and applications, including self-driving vehicles. We invite you to join us on…

Screaming Circuits: Signal To Noise Ratio

Signal to noise ratio is a pretty important factor in the world of electronics design, especially in Rf and analog design. Strangely enough, it’s also a critical part of marketing. In many parts of the engineering community, the term “Marketing” essentially has a similar definition as the term “deception.” Point of fact, that is not the definition of the term. But a low signal to noise ratio can make it seem so. Fundamentally, marketing is about getting factual information to…

New finding of particle physics may help to explain the absence of antimatter — ScienceDaily

In the Standard Model of particle physics, there is almost no difference between matter and antimatter. But there is an abundance of evidence that our observable universe is made up only of matter — if there was any antimatter, it would annihilate with nearby matter to produce very high intensity gamma radiation, which has not been observed. Therefore, figuring out how we ended up with an abundance of only matter is one of the biggest open questions in particle physics.…

My Journey from Working as a Fabric Weaver in Ethiopia to Becoming a Software Engineer at Uber in San Francisco

By Samuel Zemedkun I was born in Addis Ababa, Ethiopia and was raised there with my five younger sisters. My father made traditional fabrics, weaving one thread at a time. Weaving in Ethiopia is a family business and every member of the family plays a role. My mother, my siblings, and I helped prepare the threads. In a weaving family, boys typically graduate from preparing threads to making fabrics around the age of 12. My uncle encouraged my father to…
