Journal ArticleDOI
Fourier transform channeled spectropolarimetry in the MWIR.
TL;DR: A complete Fourier Transform Spectropolarimeter in the MWIR is demonstrated and an improved model is provided to simulate the effects of absorption within the crystal, and a modified calibration technique is introduced to account for this absorption.
Journal ArticleDOI
Phase-locking and frustration in an array of nonlinear spin-torque nano-oscillators
TL;DR: In this paper, the cooperative dynamics of an array of coupled spin-torque nano-oscillators (STNOs) can be controlled by introducing an additional external phase shift βc between microwave current, which couples STNOs, and microwave voltage on the array.
Proceedings ArticleDOI
Wavelet-based ground vehicle recognition using acoustic signals
TL;DR: An algorithm that provides an automated, fast signal recognition once implemented in a real-time hardware system and using wavelet preprocessing, feature extraction and compact signal representation, and a simple but effective statistical pattern matching.
Journal ArticleDOI
Excitation of self-localized spin-wave bullets by spin-polarized current in in-plane magnetized magnetic nanocontacts : A micromagnetic study

TL;DR: In this article, it was shown by micromagnetic simulation that a current-driven in-plane magnetized magnetic nanocontact, besides a quasilinear propagating (Slonczewski) spin-wave mode, can also support a nonlinear self-localized spinwave ''bullet'' mode that exists in a much wider range of bias currents.
Proceedings ArticleDOI
A real-time vehicle detection and tracking system in outdoor traffic scenes
TL;DR: It is shown through experiments that MVDT is effective in detecting moving vehicles in various outdoor scenes and can indeed reach real-time operation requirements.
