摘要:... The main purpose of this paper is to establish and exploit the algebraic structure of some repeated-root two dimensional constacyclic codes of length 2 p s . 2 k over the finite field F p m . Moreover, we study all self-dual repeated-root two-dimensional ( λ , 1 ) -constacy...

摘要:A new two-dimensional(spectral/spatial) optical code division multiple access is developed by using one-dimensional Multi-Service code. The spectral/spatial proposed system can suppress the multiple access interference (MAI) by using the MAI cancellation property. The numerical ...

摘要:Abstract We present a new version of the Athena code, which solves magnetohydrodynamic equations in two-dimensional space. This new implementation, which we have named Athena-GPU, uses CUDA architecture to allow the code execution on Graphical Processor Unit (GPU). The Athena-GPU...

摘要:Abstract(#br)A two-dimensional code of pictures is defined as a set X ⊆ Σ ⁎ ⁎ such that any picture over Σ is tilable in at most one way with pictures in X . It has been proved that it is undecidable whether a finite set of pictures is a code. Here we introduce two c...

摘要:Abstract(#br)When a two-dimensional bar code is away from a camera’s focus, the image is blurred by the convolution of the point spread function. In the presence of noise, the out-of-focus deblurring is an ill-posed problem. The two-dimensional bar code image has a very sp...

摘要:... A two-dimensional code spatiotemporal modeling method is proposed in this paper. We apply the two-dimensional code as an information carrier to store object’s characteristics (object’s ID, attributes, instructions, spatiotemporal data, etc.), the smartphone as a mobile...

摘要:Abstract(#br)The design of a new family of two-dimensional single pulse per column codes for optical code division multiple access (OCDMA) networks is reported. The 1-D modified pseudo-noise codes have been known to be orthogonal and their generation and system design based on th...

摘要:Abstract(#br)Current advances in reader technology offer users of two-dimensional bar codes many choices in selecting a hand-held reader for their particular application. Specifications exist that describe required functionality for various scanning technologies, but little work ...

摘要:Abstract(#br)A two-dimensional hybrid code is used to simulate processes related to the onset of the substorm expansive phase that take place in the midnight meridian plane of the magnetosphere. The simulation domain extends from the Earth's ionosphere to 35 Earth radii in the...
