Next-generation angular distribution models for top-of-atmosphere radiative flux calculation from CERES instruments: validation [PDF]

open access: yesAtmospheric 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.

UWB pulse detection and TOA estimation using GLRT

open access: yesEURASIP 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

open access: yesJournal 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

On the use of a satellite remote-sensing-based approach for determining aerosol direct radiative effect over land: a case study over China [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
A satellite-based approach to derive the aerosol direct shortwave (SW) radiative effect (ADRE) was studied in an environment with highly variable aerosol conditions over eastern China from March to October 2009. The method is based on using coincident SW

A mobile swabbing booth to address Singapore GPs’ concerns about swabber protection: human-centred design during the COVID-19 pandemic

open access: yesBMC Family Practice, 2021
Background During the COVID-19 pandemic, the Ministry of Health asked Singapore’s private general practitioners (GPs) to perform swab testing in their clinics, but some GPs had concerns about swabber protection. Our aim was to develop a swabbing booth to

Optimization of a Time-of-Arrival-Ridge Estimation Iterative Model for Ultra-Wideband Positioning in a Long Linear Area

open access: yesSensors
Ultra-wideband (UWB) technology is widely used for high-precision indoor positioning due to its adaptability to various environments. However, in long linear areas, such as tunnels or corridors, the near-linear deployment of base stations caused by ...

TOA und Rückfallrisikoreduzierung:eine Einschätzung zur Verzerrungdurch Selbstselektion

open access: yesTOA-magazin, 2020
Die Rückfallquote spielt eine zentrale Rolle in der Forschung zu Restorative Justice (RJ). Ein Grund dafür ist der zunehmende Einsatz von RJ innerhalb der Strafjustiz. Für Regierungen und Gesellschaften ist es wichtig, ihre Reaktionen auf Kriminalität so auszurichten, dass Rückfälligkeit reduziert und somit die öffentliche Sicherheit verbessert wird ...
