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 ...

* (i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]). * You are given a target value to search. If found in the array return its * index, otherwise return -1. * You may assume no duplicate exists in ...

The looming challenges of quantum computing have prompted the Java Platform to implement two advanced cryptographic solutions in its upcoming release, Java 24, slated for March 2025. Quantum computers ...

The November 2024 core update took three weeks to complete. With the update complete, now is the time to analyze traffic changes. Recovery from ranking drops can take several months with no guaranteed ...

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 ...
