On-demand satellite payload execution strategy for natural disasters monitoring using LoRa: observation requirements and optimum medium access layer mechanisms
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-01)
Article
Open AccessNatural disasters and catastrophes are responsible for numerous casualties and important economic losses. They can be monitored either with in-situ or spaceborne instruments. However, these monitoring systems are not ... -
Clouds’ microphysical properties and their relationship with lightning activity in northeast Brazil
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-11-01)
Article
Open AccessThe Northeast region of Brazil (NEB) has a high rate of deaths from lightning strikes (18% of the country’s total). The region has states, such as Piauí, with high mortality rates (1.8 deaths per million), much higher than ... -
Assessing Obukhov length and friction velocity from floating lidar observations: A data screening and sensitivity computation approach
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-03-14)
Article
Open AccessThis work presents a parametric-solver algorithm for estimating atmospheric stability and friction velocity from floating Doppler wind lidar (FDWL) observations close to the mast of IJmuiden in the North Sea. The focus of ... -
Quantum multiple hypothesis testing based on a sequential discarding scheme
(Institute of Electrical and Electronics Engineers (IEEE), 2022-01-14)
Article
Open AccessWe consider the quantum multiple hypothesis testing problem, focusing on the case of hypothesis represented by pure states. A sequential adaptive algorithm is derived and analyzed first. This strategy exhibits a decay rate ... -
Motivating a synergistic mixing-layer height retrieval method using backscatter lidar returns and microwave-radiometer temperature observations
(Institute of Electrical and Electronics Engineers (IEEE), 2022-03-10)
Article
