Signal processing: Flight delays

Introduction This article is an aside from a previous article on machine learning. The dataframe used in this tutorial (flown_noNA) is derived in the previous article after ingesting multiple CSV files, combining data, and removing redundancies within the resulting...

In our last discussion, we took a look at linear regressions using a marketing example centered around monthly sales. In addition to being able to fit our previous data sales, we’d also backed out a linear fit (with [math] r^2 = 0.965 [/math] that we could use...

Braided cable modeling

Introduction    The thought of complex electronics often brings up imagery of wires and cables, connecting electrical components on a circuit board to other hardware components. Conventionally, these cables are coaxial (so named due to the central conducting...

Introduction    The previous discussions on Radar Cross-Section (RCS) and electromagnetic (EM) coupling suggested that radiation from any number of random sources can be coupled onto, and radiate from, small features with specific geometries. But this turns out to be...
