Simultaneous ocean cross-section and rainfall measurements from space with a nadir-pointing radar [PDF]

A method to determine simultaneously the rainfall rate and the normalized backscattering cross section of the surface was evaluated. The method is based on the mirror reflected power, p sub m which corresponds to the portion of the incident power ...

Short‐Term Scheduling Optimization of a Single‐Pipeline Refining System With High Melting Point Crude Oil

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In order to reflect the actual production situation more comprehensively and optimize the production cost, this paper solves the short‐term scheduling optimization problem for a single pipeline containing high melting point crude oil. Based on the refining plan given by the upper layer, a multi‐objective optimization model with high melting ...

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

Archaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

Archaeological Prospection, EarlyView.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...
