Sparse Array Design via Fractal Geometries [PDF]

open access: yes, 2020
Sparse sensor arrays have attracted considerable attention in various fields such as radar, array processing, ultrasound imaging and communications. In the context of correlation-based processing, such arrays enable to resolve more uncorrelated sources than physical sensors.

A Monte Carlo simulation of the Sudbury Neutrino Observatory proportional counters [PDF]

open access: yes, 2011
The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of 3He proportional counters to the detector. The purpose of this Neutral Current Detection (NCD) array was to observe neutrons resulting from neutral-current solar ...

Generalized-Capon Method for Diff-Tomo SAR Analyses of Decorrelating Scatterers

open access: yesRemote Sensing, 2019
In synthetic aperture radar (SAR) remote sensing, Differential Tomography (Diff-Tomo) is developing as a powerful crossing of the mature Differential SAR Interferometry and the emerged 3D SAR Tomography.

A High Resolution Optimum 2D Coprime Planar Array [PDF]

open access: yesarXiv, 2022
Designing a new class of rectangular two-dimensional sparse array to enhance the signal resolving capabilities with a limited number of sensors has always been a challenge. We explore the non-uniformity of the sparse arrays to enhance the Degrees of Freedom (DOF) by considering the under-determined cases using the concept of the virtual array.

Mixed-signal CNN array chips for image processing [PDF]

open access: yes, 1996
Due to their local connectivity and wide functional capabilities, cellular nonlinear networks (CNN) are excellent candidates for the implementation of image processing algorithms using VLSI analog parallel arrays.

Synthesis of Sparse Linear Arrays via Low-Rank Hankel Matrix Completion [PDF]

open access: yesarXiv, 2022
In the process of realizing the synthesis of the antenna array synthesis, it is of practical significance to arrange the nonuniform array and reduce the number of elements. According to the Matrix Pencil Method (MPM), we proposed an improved nonuniform array algorithm for reducing the number of array elements.

Emotion based attentional priority for storage in visual short-term memory [PDF]

open access: yes, 2014
A plethora of research demonstrates that the processing of emotional faces is prioritised over non-emotive stimuli when cognitive resources are limited (this is known as ‘emotional superiority’).

Query processing techniques for arrays [PDF]

open access: yesProceedings of the 1999 ACM SIGMOD international conference on Management of data, 1999
Arrays are an appropriate data model for images, gridded output from computational models, and other types of data. This paper describes an approach to array query processing. Queries are expressed in AML, a logical algebra that is easily extended with user-defined functions to support a wide variety of array operations.
