Active optical sensing of canopies in pasture management

Spectroscopic Remote Sensing of Non-Structural Carbohydrates in Forest Canopies

Non-structural carbohydrates (NSC) are products of photosynthesis, and leaf NSC concentration may be a prognostic indicator of climate-change tolerance in woody plants. However, measurement of leaf NSC is prohibitively labor intensive, especially in tropical forests, where foliage is difficult to access and where NSC concentrations vary enormously by species and across environments. Imaging spe...

Sensor management using an active sensing approach

An approach that is common in the machine learning literature, known as active sensing, is applied to provide a method for managing agile sensors in a dynamic environment. We adopt an active sensing approach to scheduling sensors for multiple target tracking applications that combines particle filtering, predictive density estimation, and relative entropy maximization. Specifically, the goal of...

Optical Packet Buffers with Active Queue Management

Active queue management (AQM) is an important function in today’s core routers that will be required in the future optical internet core. A recently reported novel architecture for optical packet buffers is extended by implementing necessary AQM functions. The suggested AQM scheme is validated and explore via simulations.

Active-passive Optical Remote Sensing for Weather and Climate Research

Studying optical properties of atmospheric aerosol is important because aerosol affects people around the world significantly. Aerosol can directly affect climate change by scattering and absorption of solar and other radiations, and also indirectly affect the radiation by affecting cloud formation. Tropospheric aerosol is associated with air pollution and adverse health effects. These effects ...
