Creating ‘digital twins’ at scale to improve drone deliveries

MIT researchers propose a formal mathematical representation of a digital twin and its associated physical asset, and demonstrate how their formulation naturally integrates data, predictive models, and decision-making to enable the creation of a structural digital twin for a self-aware unpiloted aerial vehicle that dynamically replans its mission in response to in-flight structural damage.

An atomic look at lithium-rich batteries — ScienceDaily

Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium-ion, many challenges still exist — like achieving higher density and suppressing dendrite growth. Experts are racing to address the growing, global need for energy-efficient and safe batteries. The electrification of heavy-duty vehicles and aircraft requires batteries with more energy density. A team of researchers believes a paradigm shift is necessary to…

Technique inspired by lace making could someday weave structures in space

Researchers were able to describe the mathematics that underlie many forms that can be created from thin strips of flexible material. The techniques could assist to form materials that change shape to improve performance as conditions change. Credit: Neil Adelantar Lauren Dreier was paging through a 19th century book by the German architect Gottfried Semper when she spotted some intriguing patterns inspired by lace. A professional artist and designer who often incorporates technology into her work, Dreier, who is also…

PCB Assembly Services – Screaming Circuits: Screaming Circuits in Space

Between reusable rockets, rovers and helicopters on Mars and massive satellite constellations, the world of (world of??) space exploration is full of excitement these days. Oregon, where we live, is getting in on the action too. Screaming Circuits builds boards that go up and out, but due to the nature of our business, we can’t often talk about it. One project we can talk about is the Portland State Aerospace Society’s OreSat project. What it is: Screaming Circuits has assembled…

Robotic navigation tech will explore the deep ocean

The Orpheus submersible robot is being developed by Woods Hole Oceanographic Institute and JPL to explore the deep ocean autonomously. Credit: NASA/JPL-Caltech On May 14, the National Oceanic and Atmospheric Administration (NOAA) ship Okeanos Explorer will depart from Port Canaveral in Florida on a two-week expedition led by NOAA Ocean Exploration, featuring the technology demonstration of an autonomous underwater vehicle. Called Orpheus, this new class of submersible robot will showcase a system that will help it find its way and…

Flying at up to Mach 16 could become reality with UCF’s developing propulsion system

Credit: Unsplash/CC0 Public Domain University of Central Florida researchers are building on their technology that could pave the way for hypersonic flight, such as travel from New York to Los Angeles in under 30 minutes. In their latest research published in the journal Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating a special hypersonic reaction chamber for jet engines. “There is an intensifying international effort to…

3D printing could be used in search for black holes

Cotton (NRAO/AUI/NSF), and the Hubble Heritage Team (STScI/AURA) An X-ray telescope designed to search for supermassive black holes could be built using a novel 3D-printing technique called plasma metal deposition. The ESA space telescope—which would also be used to map hot gas structures and determine their physical properties—is due to be launched in 2033. As part of a project to evaluate…

PCB Assembly Services – Screaming Circuits: A look back on our Supply Chain challenges from the year 2031

Like most of us, I’ve been living in a start/stop, forward/backwards world for the last year and a few months. I can’t tell if the pandemic is closer to being over or if the light at the end of the tunnel is just another oncoming train. I can’t tell if we’re any closer to a “new normal”, if there will be a “new normal” or if the concept of “normal” even exists anymore. Or maybe I’m just asleep and in…

Mizzou Space Program launches into Argonia Cup

The small village of Argonia, Kansas, is probably not your first choice of destinations for a spring break trip. However, eight members of the Mizzou Space Program (MSP) traveled there to participate in a rocketry contest this year. This year’s Argonia Cup Collegiate Rocketry Competition featured 17 teams from eight states, including one team from Michigan, battling for the top…
