An array is not useful in places where we have operations like insert in the middle, delete from the middle, and search in unsorted data. If you only search occasionally: Linear search in an array or ...

Ramming a shin into a coffee table. Bumping a knee into that rod under your desk. Taking a tumble off a bike. These things tend to hurt like [redacted], so you probably won’t be surprised when you ...

SELECT map_subset(c0, c1) FROM ( VALUES ( MAP(ARRAY[ARRAY[1, 2]], ARRAY[1]), ARRAY[ARRAY[1, NULL], ARRAY[2, NULL]] ) ) t(c0, c1); returns "ARRAY comparison not ...

Python files developed to simulate 2D random array patterns, and transform regular uniform arrays to pseudo random through side lobe minimization.

Abstract: This paper proposes a circularly polarized beamforming technique on volumetric random arrays with each antenna aligned deliberately. This technique seeks to advance the capabilities of ...

ABSTRACT: In high frequency surface wave radar (HFSWR) applications, range and azimuth resolutions are usually lim-ited by the bandwidth of waveforms and the physical dimension of the radar aperture, ...

Abstract: In engineering, random errors in radiating element positions caused by the manufacturing and assembly processes could lead to degradation of the radiation performance of an antenna array. In ...

This paper proposes a three-dimensional (3-D) amplitude tapering technique on volumetric random arrays to minimize array sidelobes and emulate phased array operations on mobile platforms. Our ultimate ...
