CAD model of the #tricycle subframe. The chain ring is very nearly as big as the front wheel (80 teeth!). It drives an epicyclic gearbox mounted in the nose of the vehicle, which also has a disc brake. The epicyclic will drive a secondary chain via a sprocket mounted to the left hand spoke flange, but this is not yet shown. There will be no ratchet on the secondary chain, so the disk brake on the…

Team sports can lower blood pressure and improve function in patients with chronic diseases
New research from the University of Copenhagen shows that team sports are a highly effective and potentially life-extending form of exercise for patients with high blood pressure and COPD. Even after a relatively short training period involving team sports, participants showed significantly improved blood pressure.

I'm right chuffed! Even just after watering it, and having the door open for a while, our greenhouse is between 25-40 degrees C, in the last week of winter. We've already got a bunch of seedlings coming up. I think it's going to be a good summer for veggies in our household. Now if I can just find a good spot to plant that Avocado tree... 🤔

Design of the wavy wall in a partially heated channel using CFD simulations and human-assisted Bayesian optimization
This study explores heated wavy wall shape design in channel flow using machine learning, aiming to minimize temperature variation ($σ_T$) while limiting pressure loss ($Δp$). A cost function $J$ defined as a product of $σ_T$ and $Δp$ balances these competing objectives. Optimization is performed via Bayesian optimization (BO) coupled with Reynolds-Averaged Navier-Stokes (RANS) computations in an active learning loop involving up to 1000 subsequent iterations. Two shaping strategies are con…

A new crystal that 'breathes' oxygen expands possibilities for clean energy and electronics
A team of scientists from Korea and Japan has discovered a new type of crystal that can "breathe"—releasing and absorbing oxygen repeatedly at relatively low temperatures. This unique ability could transform the way we develop clean energy technologies, including fuel cells, energy-saving windows, and smart thermal devices.

The New Honda Prelude Doesn’t Have a Transmission. Here’s Why
The new Prelude's "eCVT" isn't a CVT at all; it's actually something a lot cooler.
