Over-The-Air Deramping For Multistatic Perimeter Surveillance [PDF]

open access: yes, 2015
This paper explores the use of an over-the-air deramping (OTAD) system as a solution for perimeter surveillance. Over-the-air deramping is a technique for wirelessly synchronising distributed passive FMCW radar nodes to a dual-frequency master FMCW ...

ECMWF and UK Met Office Offshore Blowing Winds: Impact of Horizontal Resolution and Coastal Orography

open access: yesJournal of Geophysical Research: Atmospheres, Volume 129, Issue 6, 28 March 2024.
Abstract We analyze the performance of the European Centre for Medium‐Range Weather Forecasts (ECMWF) and UK Met Office (UKMO) meteorological models in predicting offshore blowing wind in coastal areas. Our attention is mainly on the Mediterranean coast, up to 200 km distance from the shore. We compare forecast neutral winds with Advanced Scatterometer

Research on the capacity cost allocation and the electricity capacity price optimization method for a power system based on the BARY‐GA algorithm

open access: yesEnergy Science &Engineering, Volume 12, Issue 1, Page 168-180, January 2024.
Description: This work studied and proposed a mechanism for the formation of capacity and electricity prices based on the proportion of allowed income and fixed costs at different voltage levels. The genetic algorithm (GA) has been proposed to calculate the electricity capacity price and electricity quantity's electricity price at all levels of load ...

TS-MUWSN: Time synchronization for mobile underwater sensor networks [PDF]

open access: yes, 2016
Time synchronization is an important, yet challenging, problem in underwater sensor networks (UWSNs). This challenge can be attributed to: 1) messaging timestamping; 2) node mobility; and 3) Doppler scale effect. To mitigate these problems, we present an

Improving Sandstorm Simulations by Parameterizing Form Drag From Subgrid Sand Dunes Using 30‐m‐Resolution Terrain Data

open access: yesGeophysical Research Letters
Surface and near‐surface wind speeds, critical factors for dust emission, are often overestimated in desert regions by models, leading to exaggerated predictions of sandstorm extent and dust concentration. This study implements a new turbulent orographic
