Absorptive Weak Plume Detection on Gaussian and Non-Gaussian Background Clutter
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 For additive signals on Gaussian clutter, the optimal detector is a linear matched filter that is adapted to the known signal and the covariance of the background. This adaptive matched filter is widely used for gas-phase plume detection, even though the

Advanced Science, EarlyView.Inspired by nature's competitive maneuvers, this study introduces a combustion‐driven soft actuator that powers a multi‐modal “Jump‐and‐Fly Catbot” (JFC). With millisecond response, high‐force output (over 70 times its weight) and precise control (error within 5%), the robot can jump, fly, hover, and escape from challenging environments, achieving ...

Advanced Science, EarlyView.This study presents a hierarchically channeled graphitized nanoarchitecture (HPGC‐Z67) as a novel nano‐diagnostic platform. It enables sensitive and efficient N‐glycan extraction from plasma, significantly reducing processing time and cost. The platform identifies pivotal N‐glycans to accurately differentiate between infectious and non‐infectious ...

Variational Bayesian Based Adaptive Shifted Rayleigh Filter for Bearings-Only Tracking in Clutters
Sensors, 2019 This paper considers bearings-only target tracking in clutters with uncertain clutter probability. The traditional shifted Rayleigh filter (SRF), which assumes known clutter probability, may have degraded performance in challenging scenarios.

Clutter tuning for bistatic clutter control [PDF]
Proceedings of the 2001 IEEE Radar Conference (Cat. No.01CH37200), 2002 A radar modeling and simulation tool known as RLSTAP is used to model a bistatic clutter tuning scenario. The transmit system and the receive system "circle" the ground patch where the target lies in opposite senses so the Doppler shift due to the motion of the transmit (Tx) system is cancelled by an equal and opposite Doppler shift due to the motion ...

Low‐Power Control Of Resistance Switching Transitions in First‐Order Memristors
Advanced Electronic Materials, EarlyView.Joule losses are a serious concern in modern integrated circuit design. In this regard, minimizing the energy necessary for programming memristors should be handled with care. This manuscript presents an optimal control framework, allowing to derive energy‐efficient programming voltage protocols for resistance switching devices. Following this approach,

Radar Constant-Modulus Waveform Design with Prior Information of the Extended Target and Clutter
Sensors, 2016 Radar waveform design is of great importance for radar system performances and has drawn considerable attention recently. Constant modulus is an important waveform design consideration, both from the point of view of hardware realization and to allow for
