Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that ...

Vectors, lists, arrays, matrices and data frames -- a look at five of the most fundamental data structures built into R. Among my colleagues, R is one of the fastest-growing programming languages.

Optical computing uses photons instead of electrons to perform computations, which can significantly increase the speed and energy efficiency of computations by overcoming the inherent limitations of ...

An image consists of a rectangular array of pixels where each one is assigned a colour. For example, here is an image with 9 pixels, each pixel is assigned a specific colour. We can represent this ...

Pickering Interfaces has introduced 32 x 8 PXI RF matrix modules that fit into two chassis slots and offer a usable bandwidth up to 300MHz. Called 40-724 (PXI interface) and 42-724 (PXIe interface), ...
