Abstract: Two-dimensional sparse arrays with hole-free difference coarrays, like billboard arrays and open box arrays, can identify O(N 2) uncorrelated source directions (DOA) using N sensors. These ...

If Monster Train 2 somehow isn't enough of a test for you already, these Dimensional Challenges certainly ramp things up.

Implementation in java of two-dimensional collections, giving special focusing on matrices.

GitHub is where people build software. More than 150 million people use GitHub to discover, fork, and contribute to over 420 million projects.

In our experiments, we generate arrays of up to 50 optical tweezers arranged in arbitrary two-dimensional geometries, each containing a single cold atom, and separated by distances of a few ...
