Extraction of Liana Stems Using Geometric Features from Terrestrial Laser Scanning Point Clouds
Remote Sensing, 2022 Lianas are self-supporting systems that are increasing their dominance in tropical forests due to climate change. As lianas increase tree mortality and reduce tree growth, one key challenge in ecological remote sensing is the separation of a liana and ...

Computational Method for Wavefront Sensing Based on Transport-of-Intensity Equation
Photonics, 2021 Recently the transport-of-intensity equation as a phase imaging method turned out as an effective microscopy method that does not require the use of high-resolution optical systems and a priori information about the object.

Effective radius of cloud droplets by ground‐based remote sensing: Relationship to aerosol [PDF]
Journal of Geophysical Research: Atmospheres, 2003 Enhancement of cloud droplet number concentration by anthropogenic aerosols has previously been demonstrated by in‐situ measurements, but there remains large uncertainty in the resultant enhancement of cloud optical depth and reflectivity. Detection of this effect is made difficult by the large inherent variability in cloud liquid water path (LWP); the

Characterization of Long-period Grating Refractive Index Sensors and Their Applications
Sensors, 2009 The influence of grating length and bend radius of long-period gratings (LPGs) on refractive index sensing was examined. Sensitivity to refractive indexes smaller than that of silica could be enhanced by bending LPGs.

Mutual Support by Sensor-Attacker Team for a Passive Target
IEEE Open Journal of Control SystemsWe introduce a pursuit game played between a team of a sensor and an attacker and a mobile target in the unbounded Euclidean plane. The target is faster than the sensor, but slower than the attacker.
