Factors influencing microtremor data collected using nested-triangular array configurations

Gröbner Bases of Nested Configurations

In this paper we introduce a new and large family of configurations whose toric ideals possess quadratic Gröbner bases. As an application, a generalization of algebras of Segre–Veronese type will be studied.

Ocular microtremor measurement using laser-speckle metrology.

We describe a novel, noninvasive measurement approach for recording a small involuntary tremor of the eye known as ocular microtremor. The method is based on measuring out-of-plane angular displacements of a target by using laser-speckle correlation of images recorded in the Fourier plane of a lens. The system has a dynamic range of 4 to 5000 μrad, resolution of 4 μrad, and a bandwidth of 250 H...

DOA estimation of speech signal using equilateral-triangular microphone array

In this contribution, we propose a DOA (Direction Of Arrival) estimation method of speech signal whose angular resolution is almost uniform with respect to DOA. Our previous DOA estimation method[1] achieves high precision with only two microphones, however its resolution degrades as the propagating direction apart from the array broadside. In the proposed method, the equilateral-triangular mic...

ASKAP Array Configurations: Technical Studies

In this document we explore the possibilities for different array configurations for the Australian Square Kilometre Array Pathfinder (ASKAP) based on the requirements of the science case (Johnston et al. 2007). The configurations are constrained by the land available at the Murchison Radio Observatory, a mask of unsuitable locations within the site, and the budget for the backend computing. We...
