Mode-k flattening

In multi-linear algebra, mode-k flattening (also matricisation, matricizing, or unfolding) is an operation on tensor (a multi-dimensional array) denoted by turning it into a matrix (a two-dimensional array). Matricization may be regarded as a generalization of the mathematical concept of vectorization. Matricization may be applied in connection with determination of the factors in the PARAFAC model.

Ratchet mechanism 12

There are two pawls. The green pushes the pink gear and is not always in contact with it (unlike ordinary ratchet mechanism). The blue keeps the wheel immobile when the green does not push the gear. STL files of this video are available at http://www.mediafire.com/download/z49sftdn4amm16a/

FPGA Design with MATLAB, Part 4: Converting to Fixed Point

Efficient hardware implementation requires quantizing your data types to fixed point. Signal-processing algorithms can be challenging to convert while maintaining required precision, especially if you are writing RTL by hand. The Model-Based Design approach lets you easily explore and visu

Toilet Paper Turned Back to Solid Wood by Hydraulic Press

I stick a toilet paper roll in the hydraulic press to try to turn it back to solid wood. As the press comes down on the toilet paper roll, you can't see much but the toilet paper gets crushed until the fibers fuse into one solid piece. I show just how hard this wood is by trying to drive a
