A 'digital twin' is a model that evolves over the lifetime of a physical asset. So if the state of the real device changes, so does the model (data assimilation). Likewise, one can…

Yes! Claude created nearly all of the interface.

Yeah, as shown it's just a bunch of models. The real magic happens when this is connected to hardware and we can do things like data assimilation and control.

100% agree - each roaster is slightly different, with different measurement schemes and other device peculiarities. This makes sharing coffee roasting profiles basically impossible…

Keep going! Getting close to the melting point of Stainless 316 (1400C? I forget.)

Working on it! In fact, this was my original goal; Model Predictive Control for my roasters. I've been able to get this working on a fluid bed roaster but I've yet to try it for my…

I built this website to host a data-driven model of my coffee sample roaster. I realized after 20 or so batches on the machine that while the controls are intuitive (heat, fan, and…

That’s me - that video summarized my dissertation work. I did some follow-on modeling work using neural ODEs that’s pretty neat, too: https://aip.scitation.org/doi/10.1063/5.006362…
