Most array signal processing systems u e delay-and-sum beamforming to estimate source bearings. This paper demonstrates the close relationship between beamforming and frequency-wavenumber spectrum analysis. The latter approach as computational dvantages over beamforming when the noise is spatially correlated. The wavenumber approach is used to'derive the array response of a general inear or pla...

This paper proposes programmable architectures and design methods for numeric function generators (NFGs) of two-variable functions. To realize a twovariable function in hardware, we partition a given domain of the function into segments, and approximate the function by a polynomial in each segment. This paper introduces two planar segmentation algorithms that efficiently partition a domain of a...

DESPEC is one of the experiments of the low-energy branch project of the future installations at FAIR (GSI). The main goal of this experiment is to study the decay properties of exotic nuclei. The basic instrumentation of this setup includes a set of implantation detectors, a Ge array and neutron detectors. Presently the collaboration is considering two possible setups for the Ge array. One pos...

At the Low Energy Branch of the future FAIR facility, the fragmented beams from the Super-FRS are slowed down in energy or completely stopped. One of the experiments proposed at this branch is DESPEC (decay spectroscopy) where studies of the decay of short-lived nuclei, either in their ground state or in an isomeric state are planned. The ions at some tens of MeV/u will be deeply implanted in a...

abstract Many practical routing problems such as BGA, PGA and test xture routing involve routing two-terminal nets on a plane with exchangeable pins. In this paper, we unify these diierent problems as instances of the Planar Interchangeable 2-Terminal Routing (PI2TR) problem. We formulate the problem as ows in a routing network. Secondly, we show that PI2TR is NP-complete by reduction from sati...

This paper proposes and designs a new method of dualband omnidirectional planar microstrip antenna array. A cascade of transposed microstrip lines have been adapted to produce effective antenna structures that radiate omnidirectionally, with high efficiency, low reflection, and useful radiation patterns. In this paper, the antenna structure has been found to have low-pass characteristics due to...

An n × n × p proper array is a three-dimensional array composed of directed cubes that obeys certain constraints. Because of these constraints, the n× n× p proper arrays may be classified via a schema in which each n× n× p proper array is associated with a particular n× n planar face. By representing each connected component present in the n × n planar face with a distinct letter, and the posit...

Let m 6= n. An m × n × p proper array is a three-dimensional rectangular array composed of directed cubes that obeys certain constraints. Because of these constraints, the m × n × p proper arrays may be classified via a schema in which each m×n×p proper array is associated with a particular m×n planar face. By representing each connected component present in the m × n planar face with a distinc...
