Reminder - please join us Wednesday, June 5 at 10am PT for the Flight Opportunities webinar spotlighting Purdue University’s cryogenic fluid management tech that researchers advanced through parabolic flight campaigns with Zero Gravity Corporation. Researchers from Purdue and NASA’s Glenn Research Center measured cryogenic two-phase heat transfer coefficients to help develop more precise models of flow boiling rates and improve predictive capabilities for in-space propellant transfer systems. The work is providing insights that could advance future lunar and deep space exploration missions as well as terrestrial applications.

Imagine a survey that asks American consumers to name three or more products that use ultrasound. Many would have trouble naming more than one. Medical imaging machines may be the most common answer. That’s not surprising, given that ultrasonic devices are largely hidden outside of a healthcare setting. Lately, however, ultrasound technology is emerging in many more places. These places are unexpected, in the middle of our personal therapies for wellness, our recreational equipment, and even in our mobile devices. Some are literally at our fingertips. In this post, #Mesoteryx reveals four unexpected ultrasound applications. Check it out at mesoteryx.blogspot.com.

Washington sets aside $240 million for pilot shortages as busy summer travel season starts - Yahoo News. How can "AI" help reduce pilot shortage? Our recent research on this topic explored exactly that in collaboration with the Aerospace Systems Design Laboratory (ASDL) and the Naval Postgraduate School By applying machine learning techniques to 10 years of pilot training data, we demonstrated: 🔹 Early identification of late-stage attrition of pilot trainees, using their initial test scores 🔹 $20M in savings per year for the US Navy Identifying high-risk aviators early enables proactive measures to boost success rates and optimize training resources. At GTC Analytics, we're pushing the boundaries of AI/ML to generate actionable intelligence across various domains. Explore our findings to see how they can transform your operations.

Appreciating James Orgill in his youtube com@TheActionLab, for an almost more logical definition of "Entropy", which I've yet heard in ~40 years. Bravo! So, does my use of the "almost" clause, make my result of seeing that video, a higher 'Entropy of Entropy' result? 🤔 Seems to me, in having a practical engineering expectation: Entropy as a metric, is only a means to correct something from any numerical theory, which routinely doesn't match measurements well enough. Arising from the observers POV, represented as a numerically modeled system. Defining the "Entropic Force" of a elastic band in tension, which most engineers would define as the spring-equation (delta-F = K x delta-L). So, when has spring-force with stored-potential energy, ever been redefined fully as an "entropic force" of restoration at the molecular assembly ensemble scale, and/or the multi-atom ensemble scale levels? Wow, POV and system definition assumptions, really affect the calculable actual measurable work/energy, plus entropy value. (E g., Total Energy is still being defined by potential + kinetic + entropic energies of all continuum-scales at a fixed instant? ) Thus, the term "Entropy of Entropy', is not just a nonsensical meandering of a chronically scientifically ignorant, engineering-POV person. (Am I alone in this whim?) https://lnkd.in/eJZk6sdw

We'll be at the XPONENTIAL Show in San Diego April 23-25 in BOOTH 5543! Stop by, sign up and receive our Show Pricing Special - up to 8 UAS training program modules for $325! If you operate a Small Unmanned Aircraft System (SUAS) for non-recreational purposes, you are responsible for ensuring it is safe to operate according to 14 CFR 107.15 (a) and (b). The FAA holds Remote Pilots in Command (RPIC) responsible for compliance with the rules of the air, just as drivers are responsible for following traffic rules. If an "accident" occurs, the first thing the FAA will look at is your training and adherence to the rules.

Thanks to Ron F. from General Atomics' Electromagnetics Division for inviting me to opine on the challenges and opportunities of space nuclear power and propulsion. As it turns out, we have quite a bit of both. Opportunities first. I've said it before but it's worth repeating: Elon and his superb team at SpaceX have dismantled the LEO bottleneck. And that has opened the door to innovations of every kind - at least in LEO. But what it's really done is enable us to envision how we will go to (and play in) higher orbits, offering us a chance to define what sort of infrastructure we will build the future space economy *on*. The future is not LEO - it's the entire solar system. So: It won't be chemistry or solar power that get us moving, not if we're serious about creating a gold rush to orbit. Both are too constrained and deficient (i.e., insufficiently energy- and power-dense) to rapidly and efficiently connect the dots in cislunar space, and provide the megawatts on demand we know we'll need, whether the use case is civil, commercial, or defense. That leaves us with nuclear - and it's going to be fission for awhile, despite noteworthy quantities of money flowing into fusion. We can make this work - but we have to get to orbit and prove ourselves now. If we don't? Well, sunk cost is very real (see SLS). If you have it, you use it - even if it doesn't make sense. Let's make sure that what we put on orbit makes sense - commercial sense, defense sense, civil sense. Challenges? Well, we're all capital-intensive plays with some uncertainty in our regulatory story and that combo tends to scare the 💩 out of most private investors. I'd love to be introduced to any visionary folks out there with some discretionary dollars who share my passion for the space gold rush and want to find a way to get involved that gets us out and moving during our lifetimes - while we can have some fun. We can do this. 🚀 https://lnkd.in/ezq6yv_G

Dustin Miller - PolyInnovator broaches an interesting question here and I wish he had looked a little bit into personality proclivities. On the Meyer's Briggs, you find the traits of Sensing (Discrete) and iNtuitive (Broad) that set a foundation for thinking. This isn't to say that Sensing types can't be polymathic, far from it, it also doesn't mean that the intuitive will naturally become so either. Both need to be balanced but I will say, the iNtuitive types have the natural inclination to look broadly, specifically when paired with a STEM education. Still though, Polymathy is a mindset which can become a skillset, and help develop your personality proclivities even more. I do a slightly deeper dive into how everyone can develop a polymathic mindset here: https://lnkd.in/gzfMwqcX
