Abstract: The sparse array could reduce the cost of physical antennas. However, implementing wideband beamforming directly based on the covariance matrix of the received signals from the sparse array ...

This paper presents a generic beamformer design algorithm for arbitrary microphone array geometry. It makes efficient use of noise models for ambient and instrumental and microphone directivity ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

Abstract: To address the challenge of ensuring a submarine can smoothly pass through a strait and complete its mission, this article proposes using a magnetic decoy array to simulate the submarine’s ...

The library sorting problem is used across computer science for organizing far more than just books. A new solution is less than a page-width away from the theoretical ideal. Computer scientists often ...

// Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. // If target is not found in the array, return [-1, -1]. // You must ...
