organic chemistry - How would substitution reaction results differ between reacting halides with a tertiary bromoalkane vs reacting it with a primary bromoalkane?

›
Say, you conducted two separate reactions; in one, you combined $\mathrm{50~mmol}$ saturated $\ce{KCl}$ solution with $\mathrm{10~mmol}$ 1-b...

filters - Is up-sampling prior to cross-correlation useless?

›
Consider a simple case where two signals from two different sensors are cross-correlated, and the time-delay-of-arrival computed from the ab...

adaptive algorithms - Kalman filter in practice

›
I have read the description of the Kalman filter, but I am not clear on how it comes together in practice. It appears to be primarily target...
