Geodetic data analysis of VGOS experiments

2021 XXXIVth General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2021
Very Long Baseline Interferometry (VLBI) serves as one of the common geodetic methods to define the global reference frames and monitor Earth's orientation variations. The technical upgrade of the VLBI method known as the VLBI Global Observing System (VGOS) includes a critical re-design of the observed frequencies from the dual band mode (S and X band,

Effect of Hydrotreating on Catalytic Cracking of a VGO

Energy & Fuels, 1996
The effect of hydrotreating of a vacuum gas oil (VGO) feed on the activity, product composition, and quality in a microactivity test (MAT) has been studied.

Mathematical Modeling of a VGO Hydrotreating Reactor

SPE Latin American and Caribbean Petroleum Engineering Conference, 2001
Abstract This paper presents a mathematical model developed for the operating simulation of a trickle-bed reactor. Furthermore, the model has been fixed to emulate the operation of the three reactors used at the gas oil hydrotreatment reactors available at Amuay refinery (PDVSA).

Scheduling for VGOS twin-telescopes

2016
The technique of Very Long Baseline Interferometry (VLBI) allows the estimation of all five Earth Orientation Parameters (EOP), the International Celestial Reference Frame (ICRF) and it is a primary contributor to the International Terrestrial Reference Frame (ITRF), in particular with information about its scale.

VGOS observing strategy for 202

The VLBI Global Observing System (VGOS) entered operational service in 2020 with a small, northern-hemisphere-dominated network and a modest observing cadence constrained primarily by correlator capacity, data transport, and storage limitations. Since then, the network has continued to expand steadily.
