🚢 Understanding the basics of ship stability 🌊 Ever wondered how ships stay balanced on water, even in challenging conditions? This video breaks down the fundamentals of ship stability—a crucial topic for anyone in maritime engineering, naval operations, or simply passionate about the science behind the seas! ⚓ From concepts like center of gravity and buoyancy to the impact of external forces, this is your go-to guide for understanding why stability matters. 🛠️ 📽️ Watch now and dive into the world of naval safety and engineering! #ShipStability #MaritimeEngineering #NavalArchitecture #SafetyAtSea #EngineeringInsights #InnovationInMaritime

Did you know that… one and the same physics law explains why steel ships can float 🚢 and why hot air balloons can fly 🎈 This law was discovered over 2,000 years ago. The brilliant Archimedes of Syracuse is said to have formulated this principle while taking a bath. He can truly be considered the godfather of marine engineers and naval architects. #engineering #marine #naval #Archimedes #EngineerWeek #noengineersnofuture #MULTI.engineering

This conference proceedings illustrates a practical methodology to improve #covariance estimation using the principles of lucky #signalprocessing and the cumulative #coherence. Lucky processing, popularized in astro-photography, is a technique that increases signal quality by selectively keeping only a small fraction from a pool of potential snapshots. Cumulative coherence, a measure of how well a set of vectors is described by its subsets, provides the measure of “data quality” that enables the lucky processing. This approach is described practically and then applied to covariance estimation on an #acousticarray by taking a fixed duration sample of data and creating a dense set of snapshots with higher than usual overlap. From these densely sampled snapshots, the “luckiest” ones were found using cumulative coherence, and the covariance was averaged as normal. It was found that the lucky covariance estimate was successful at adaptive matched field processing and produced a less ambiguous processor output than the conventional estimator. The lucky covariance estimate had a higher estimated signal-to-noise ratio, especially when the source was at longer ranges from the #array. #mai #marineacoustics Acoustical Society of America #technology #innovation #sonar United States Naval Research Laboratory #acoustics #underwateracoustics #research https://lnkd.in/ej5MCmVB

Besides the fact that, I must admit that I was a tad-bit distracted by the Vessel on the front cover, Mazzucchi's insights on naval strategy #geopolitics in this book offers a contemporary view of potential conflicts at sea and their implications for international relations. I particularly like that this detailed analysis of modern naval strategy, set against the backdrop of growing global tensions, explores how naval power dynamics are evolving, brought about by incidents like missile attacks on vessels and the expansion of powerful navies like China's. And I've come to the conclusion that I'm interestingly and particularly drawn to this book as a result of my Bachelor's Project Research Topic 'Militarization Of The South-China Sea and Insecurity In The Asian-Pacific Region'. The book also examines the rising importance of maritime routes for global economies and security, especially after the COVID-19 pandemic highlighted their critical role. It discusses advancements in naval technologies, such as satellites, drones, and submarines. THE BIG NEWS OF THE DAY IS : It is set for release on November 13, 2024, by Éditions du Rocher. Keep an eye peeled. 👀

The Maritime Environment for Training and Analysis (META) proposed project is set to revolutionize naval training by generating realistic electromagnetic signatures in a dynamic virtual environment. META will enhance warfighter readiness for the complexities of the electromagnetic spectrum at sea.

As robot-human teams begin to make their way to the modern battlefield, maintaining a full picture of the electromagnetic spectrum (radio waves, radar systems, and every other invisible communication type) becomes exponentially more important. We're building the tools that make simulating and visualizing EMS for both training and operations.
