That concept for an intermediate platform to support far offshore platforms from japan, as a heliport base and PSV base. This design seems to be a turreted platform with a rear submerged dock

Deakin engineers look to Mother Nature for answers to power problems | Deakin
I wonder if this is a function of Reynolds number effects, so that those whale tubercle wind turbine blades can't be scaled down and need to resort to seagull wing biomimicry...

Apparently a really good book on systems engineering and project management for engineering teams. Hardcover version apparently also is very nicely printed?

Protecting the LHC from itself | symmetry magazine
Interesting that they have to spread out the beam first before hitting the dump, and the dump is made from a block of graphite. The quench protection via electrical dump to resistor grids is also interesting. I would have thought they might try to recover the power from the dump into some other storage, but I guess the safety criticality means they don't.

Practical Application Limits of Fuel Cells and Batteries for Zero Emission Vessels
Uh, they only cover batteries or liquid/gaseous hydrogen PEM fuel cells in the comparison, so kinda incomplete. So no LNG fuel cells, no fuel cell/microturbine hybrids using the microturbine combustor as a topping cycle. Also, the basic conclusion is huge vessels could run a full trip, but on liquid hydrogen only, and short trip ferries should look at batteries instead.

The Case for Learned Index Structures – Arxiv Vanity
Machine learning indexes beat b-trees, 3x faster in 10-100x less space. Run it on GPU's which are still getting faster at rates higher than CPU's, and you could have a real shift in computing, assuming you can stuff enough data into GPU RAM.

Breaking Lorentz reciprocity to overcome the time-bandwidth limit in physics and engineering | Science
Telecomms just got a huge breakthrough. But apparently radar guys in the 40's knew about using non-reciprocal resonators to keep EM from pushing back into waveform generators, but never published?
