Nested arrays and operators

ACM SIGAPL APL Quote Quad, 1992
Following the new direction taken by the ISO Standards Committee meeting in Palo Alto, during August, 1991, an extended APL standard is considered using a nested array basis with particular features from IBM's APL2 program product. APL2 develops from ISO APL with the relaxation of two early scalar constraints.

A Novel Nested Array for Real-Valued Sources Exploiting Array Motion

IEEE Signal Processing Letters, 2021
In this letter, a novel nested array is proposed which not only increases the degrees of freedom (DOF) but also reduces the mutual coupling that occurs in the general nested array structure by moving the original array only half wavelength. Here we deal with real-valued sources like AM or BPSK whereby we can explore the property of the sum coarray ...

Bounds for asymmetric nested orthogonal arrays

Discrete Mathematics
The paper explores nested orthogonal arrays (NOAs), which are widely used in statistical experiments and fractional factorial designs when different factors require different numbers of levels. It addresses the core problem of determining minimal sizes (i.e., the smallest possible number of runs) for constructing such NOAs, under asymmetry constraints (

Optimization of the inner array in a nested array Z-pinch

IEEE Conference Record - Abstracts. 1999 IEEE International Conference on Plasma Science. 26th IEEE International Conference (Cat. No.99CH36297), 1999
Summary form only given. Nested wire arrays have been used to improve pinch quality and X-ray power. Numerical simulations suggest that the inner array acts to reduce the growth of the MHD Rayleigh-Taylor (RT) instability present in the outer array prior to impact.

Stability of compression of the inner array plasma in nested arrays

Plasma Physics Reports, 2017
The implosion of nested fiber/wire arrays was studied experimentally at the Angara-5-1 facility. The outer array consisted of kapron fibers, while the inner array was made of tungsten wires. The experiments were carried out at a discharge current of 3 MA.

Nested arrays as an extension for APL

ACM SIGAPL APL Quote Quad, 1979
This workshop will be held to inform interested members of the APL community about current research on adding nested arrays to APL. The Chairman will present a brief summary of current research in the area, indicating the issues that are yet unresolved, and presenting a set of criteria for deciding them.

Systolic array implementation of nested loop programs

[1990] Proceedings of the International Conference on Application Specific Array Processors, 2002
The authors consider a formal and systematic method to convert a class of nested loop programs to single assignment codes and, when possible, to regular algorithms (RAs) for systolic array implementation. The authors concentrate on the analysis of certain imperative nested loop programs in view of the ultimate objective, which is the (semi)-automatic ...

Underwater DoA estimation based on nested array

MILCOM 2015 - 2015 IEEE Military Communications Conference, 2015
This paper generalizes a new algorithm for Direction of Arrival (DoA) estimation in one and two dimensional (1D and 2D) underwater non-uniform sensor array networks (UWSANs). The extension of augmented matrix approach from the minimum redundancy array (MRA) to the nested array and co-prime array is the main issue addressed in this work.
