Variable strength orthogonal array, as a special form of variable covering plays an important role in computer software testing and cryptography. In this paper, we study the construction arrays with two containing greater than by Galois field construct some l Fan-construction.

uniform linear array (ula)-based tapped-delay line (tdl) structure has good performance metrics when the signal sources are located at the middle angles. it offers poor performance when the signal sources are close to the array endfire. in this paper, a new approach is proposed which offers higher performance and desired beamforming on tdl structure when the wideband uncorrelated radio sources ...

A new four elements compact antenna array is presented and discussed to achieve enhanced phase resolution without sacrificing the array output power. This structure inspired by the Ormia Ochracea’s coupled ears. The analogy between this insect acute directional hearing capabilities and the electrically compact antenna array is used to enhance the array sensitivity to direction of arrival estima...

Propagation environment and antenna array configuration have significant effect on spatial correlation properties of multipleinput multiple-output (MIMO) wireless communications channels. In this paper the effect of different antenna array geometries on MIMO channel properties is investigated in urban city street grid propagation environment. Four antenna array geometries with the same number o...

Based on an integrated design of metasurface units and antenna elements, a 2-bit array with broadband low radar cross-section (RCS) covering large incident angle space is proposed in this study. The slot width's influences the reflective phase element radiation performance are analysed. Furthermore, genetic algorithm utilised to obtain coding pattern diffuse scattering characteristics. A wideba...

Milton Babbitt (1916–2011) was a composer of twelve-tone serial music noted for creating the all-partition array. One part of the problem in generating an all-partition array requires finding a covering of a pitch-class matrix by a collection of sets, each forming a region containing 12 distinct elements and corresponding to a distinct integer partition of 12. Constraint programming (CP) is a t...

Genome-wide analysis of DNA methylation has now become a relatively inexpensive technique thanks to array-based methylation profiling technologies. The recently developed Illumina Infinium MethylationEPIC BeadChip interrogates methylation at over 850,000 sites across the human genome, covering 99% of RefSeq genes. This array supersedes the widely used Infinium HumanMethylation450 BeadChip, whic...

We propose and experimentally demonstrate a planar array of optical bandpass filters composed of low loss dielectric metasurface layers sandwiched between two distributed Bragg reflectors (DBRs). The two DBRs form a Fabry-Pérot resonator whose center wavelength is controlled by the design of the transmissive metasurface layer which functions as a phase shifting element. We demonstrate an array ...
