Atmospheric monitoring for the H.E.S.S. experiment using a single scattering lidar [PDF]
, 2009 The High Energy Stereoscopic System (H.E.S.S.) is an array of 4 telescopes located in Namibia, which use the imaging atmospheric Cherenkov technique (IACT) to study astrophysical emission of gamma radiation in the energy window from 100 GeV to 50 TeV ...

Model-based inference for biomass estimation in a LiDAR sample survey in Hedmark County, Norway [PDF]
, 2011 In forest inventories, regression models are often applied to predict quantities such as biomass at the level of sampling units. In this paper, we propose a model-based inference framework for combining sampling and model errors in the variance ...

A Reconfigurable Memristive Spiking Neuron Enabling Advanced Neuromorphic Computing
Advanced Science, EarlyView.Pek Jun Tiw and co‐workers develop a reconfigurable memristive neuron that can exhibit four spiking behaviors with freely tunable spike train parameters. The neuron supports multiplexed spike encoding of multiple pieces of information. It also supports advanced neural network strategies, such as neural heterogeneity and dynamic mode switching ...

On Depolarization Lidar-Based Method for The Determination of Liquid-Cloud Microphysical Properties
EPJ Web of Conferences, 2016 Under single scattering conditions, water droplets clouds do not depolarize the backscattered light. However, backscattered light from multiple scattering will be depolarized.
