Next-generation angular distribution models for top-of-atmosphere radiative flux calculation from CERES instruments: validation [PDF]
Atmospheric Measurement Techniques, 2015 Radiative fluxes at the top of the atmosphere (TOA) from the Clouds and the Earth's Radiant Energy System (CERES) instrument are fundamental variables for understanding the Earth's energy balance and how it changes with time.

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

UWB pulse detection and TOA estimation using GLRT
EURASIP Journal on Advances in Signal Processing, 2017 In this paper, a novel statistical approach is presented for time-of-arrival (TOA) estimation based on first path (FP) pulse detection using a sub-Nyquist sampling ultra-wide band (UWB) receiver.

Development of Coupled Numerical Model between Floating Caisson and Anti-Oscillation Tanks
Journal of Marine Science and Engineering, 2023 Floating caissons can oscillate owing to ocean waves when towed to an installation site. To reduce these oscillations, free-surface anti-oscillation tanks mounted on floating caissons have been proposed. However, no coupled numerical model exists between

Maximum likelihood time-of-arrival estimation using antenna arrays: Application to global navigation satellite systems [PDF]
, 1998 The problem of estimating the time-of-arrival (TOA) of a known signal in the presence of interferences and multipath propagation is addressed. This problem, is essential in high precision receivers of the Global Navigation Satellite Systems.

A pilot variational coupled reanalysis based on the CESAM climate model
Quarterly Journal of the Royal Meteorological Society, EarlyView.Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

TOA-Based Passive Localization Constructed Over Factor Graphs: A Unified Framework
IEEE Transactions on Communications, 2019 Passive localization based on time of arrival (TOA) measurements is investigated, where the transmitted signal is reflected by a passive target and then received at several distributed receivers.

Feasibility of coupling a thermal/optical carbon analyzer to a quadrupole mass spectrometer for enhanced PM2.5 speciation [PDF]
, 2018 A thermal/optical carbon analyzer (TOA), normally used for quantification of organic carbon (OC) and elemental carbon (EC) in PM2.5 (fine particulate matter) speciation networks, was adapted to direct thermally evolved gases to an electron impact ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.(a) Organized convection: clouds are clustered at the southern edge of the domain, aligning with the warmest SST. Northeasterly winds prevail, facilitating convection confinement to the southern part of the domain. (b) ITCZ breakdown: the clouds are spread throughout the domain.
