The Euclid ERO showcase Euclid's capabilities in advance of its main mission by targeting 17 astronomical objects, including galaxy clusters, nearby galaxies, globular and star-forming regions. A total 24 hours observing time was allocated the early months operation, scientific community engaged through an public data release. We describe development pipeline to create visually compelling images while simultaneously meeting demands within launch leveraging a pragmatic data-driven strategy....
Abstract We have made substantial improvements to the previously published methods for geochemical allocation of commingled oil production and/or gas production. This new method has allowed from wells at less than 2–5% cost logging. Four case studies are shown here. In first two studies, commingling was subject approval Alaska Oil and Gas Conservation Commission (AOGCC). Before agreeing use allocation, AOGCC required well operator perform multi-month trial in which were monitored both by The...
The Euclid Wide Survey (EWS) is predicted to find approximately 170 000 galaxy-galaxy strong lenses from its lifetime observation of 14 deg^2 the sky. Detecting this many by visual inspection with professional astronomers and citizen scientists alone infeasible. Machine learning algorithms, particularly convolutional neural networks (CNNs), have been used as an automated method detecting lenses, proven fruitful in finding lens candidates. We identify major challenge be automatic detection...
The Extended Q-range Small-angle Neutron Scattering Diffractometer (EQ-SANS) instrument at the spallation neutron source (SNS), Oak Ridge, Tennessee, incorporates a 69 m3 detector vessel with vacuum system which required an upgrade respect to performance, ease of operation, and maintenance. focused on improving pumping performance as well optimizing design minimize opportunity for operational error. This provided following practical contributions:•Reduced time evacuate from atmospheric...
The Spallation Neutron Source is an accelerator-based neutron source built and operated by the U.S. Department of Energy in Oak Ridge, Tennessee. With over 10 years operation at 1 MW power above, shortcomings have been identified original vacuum pumping scheme for drift tube coupled cavity linear accelerator sections. In this article, performance these systems reviewed major areas concern are discussed. changes to system examined final design described. Finally, impact after a year with new...
The People's Republic of China (PRC) and its rapidly evolving space forces are viewed to be one the principal threats United States' national security infrastructure U.S. capability for timely force projection in Pacific Theater. This view, especially since 2007 kinetic anti-satellite (ASAT) weapons test, added emphasis Space Posture Review 2010 Department Defense's quest deterrence as a means secure sanctuary from weaponization. article will examine strategic culture PRC how it impacts...
ABSTRACT Durings its journey from a production facility to refinery, the most probable time for oil enter water is during vessel cargo-transfer operations. This paper describes origins, implementation, and effects of U.S. Coast Guard's operational regulatory program designed prevent transfer-related discharges. Statistical data USCG Pollution Incident Reporting System (PIRS) used measure effectiveness these actions. A review presented results an on-scene transfer monitoring conducted in 1972...
