Abstract: In this paper, we present a novel framework of beamforming robust for a microphone array rotation. In most array signal processing methods, the time-invariant transfer system from a source ...

RIFT2 is a Python implementation for multimodal image matching and rotation-invariant feature detection using phase congruency. You can read more about the technique in the paper "RIFT2: Speeding-up ...

Abstract: This paper presents an efficient method for the synthesis of Circular Antenna Array (CAA) using the Archimedes Optimization Algorithm (ArOA), a recent physicsinspired metaheuristic based on ...

Plug in the emitter and turn on the receiver to 30X mode. Put the ball bearing array on the lab jack. Align the emitter, receiver, and ball bearing array so that microwaves diffract off the array and ...
