Direction of Arrival Estimation Using Microphone Array Processing for Moving Humanoid Robots [PDF]
IEEE/ACM Transactions on Audio Speech and Language Processing, 2015 The auditory system of humanoid robots has gained increased attention in recent years. This system typically acquires the surrounding sound field by means of a microphone array. Signals acquired by the array are then processed using various methods.

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

Frequency–wavenumber array processing [PDF]
The Journal of the Acoustical Society of America, 1981 Most array signal processing systems use delay-and-sum beamforming to estimate source bearings. This paper demonstrates the close relationship between beamforming and frequency–wavenumber spectrum analysis. The latter approach has computational advantages over beamforming when the noise is spatially correlated. The wavenumber approach is used to derive

Improved infrasound array processing with robust estimators
Geophysical Journal International, 2018 Infrasound array data are commonly used to detect and characterize infrasonic signals from a variety of natural and anthropogenic sources. Here we examine the effectiveness of robust regression estimators (L1-norm regression, M-estimators and least ...

Coupled Canonical Polyadic Decompositions and Multiple Shift Invariance in Array Processing
IEEE Transactions on Signal Processing, 2018 The canonical polyadic decomposition (CPD) plays an important role for signal separation in array processing. The CPD model requires arrays composed of several displaced but identical subarrays. Consequently, it is less appropriate for more complex array

A flexible ultrasensitive optoelectronic sensor array for neuromorphic vision systems
Nature Communications, 2021 The challenges of developing neuromorphic vision systems inspired by the human eye come not only from how to recreate the flexibility, sophistication, and adaptability of animal systems, but also how to do so with computational efficiency and elegance ...
