  • To address this need for faster simulations, my team at IBM Research is working with the Lawrence Livermore National Lab on Cardioid, a code that simulates the human heart on the 20 Petaflop Blue Gene/Q, Sequoia.

Examples

  • Well, what this is showing us is that all of the numbers in the main cardioid, they end up stabilizing onto a single constant value.

  • So the main cardioid here, number one.

  • Cardioid is today's version of that code.

  • Phase-coherent cardioid (PCC) -- similar to PZM but less expensive.

  • A method for sound enhancement in these arrangements may consist of one or two phase-coherent cardioid (PCC) microphones placed along the front edge of the stage.

  • The cardioid is a unique shape often seen in mathematics, resembling a heart.

  • You can visualize a cardioid by tracing the path of a point on a circle as it rolls around another circle of the same size.

  • In geometry, a cardioid can be formed by using polar coordinates to plot its distinctive heart-like curve.

Morphology

cardioid = cardio + oid

The term is built from the classical combining form cardio and the suffix -oid, but these bound forms are not generally transparent to an average B1 learner and the word is technical.

Etymology

The word cardioid comes from the Greek root cardio- meaning 'heart' and the ending -oid meaning 'like' or 'shape'. So a cardioid is a 'heart-shaped' curve, which is why the curve in math and the way some microphones pick up sound look like a heart.
