In Greek mythology, Ēōs (; Ionic and Homeric Greek , AtticÉōs, "dawn", or ; AeolicAúōs, DoricĀṓs) is a Titaness and the goddess of the dawn, who rose each morning from her home at the edge of the Oceanus.

EOS (operating system)

EOS was the discontinued operating system developed by ETA Systems (a spin-off division of Control Data Corporation) for use in their ETA10 line of supercomputers in the 1980s.

EOS was preceded by and was binary executable compatible with the CDC VSOS operating system for Cyber 205. Like VSOS, EOS had demand paged virtual memory (the VS part) with 2 pages sizes for improved virtual memory performance with the ETA's faster hardware pipelines. Though it had roots in the interactive Livermore Time Sharing System (LTSS), VSOS was focused as a batch-oriented operating system. VSOS was not run at very many institutions and its application-oriented performance, while the historic focus for supercomputing, set its features behind the times because of its limited user base.

To address this feature deficiency and to make the operating system more "normal to use", the VSOS characteristics were married with UNIX characteristics in a hybrid OS. The OS was intended to be effective for both batch work that drove the hardware to its maximum or for interactive use in development from a UNIX workstation.

EOS was written mainly in Cybil, a Pascal-like programming language created by Control Data for its later Cyber operating systems. It was a new effort, as VSOS was implemented in IMPL, a Fortran-like language created for the LTSS implementation. The command line appearance of all these systems was similar to the lineage going back to UNIVAC EXEC*8.

EOS was released with early hardware deliveries and had some of the typical problems for early OS releases. Some customers delayed payment for their supercomputer installations.

ETA later released a port of UNIX for the ETA-10 line, which was more quickly accepted by their customer base. However, this port started as a single-processor kernel which did not transparently exploit the hardware architecture with up to 8 large application CPUs for applications.

Eos (magazine)

Eos, Transactions, American Geophysical Union, is a weekly magazine of Earth science published by John Wiley & Sons for the American Geophysical Union (AGU). The magazine, based in Washington, DC, publishes news, book reviews, AGU journal and meeting abstracts, meeting programs and reports, a comprehensive meetings calendar, and announcements of grants, fellowships, and employment opportunities, as well as peer-reviewed articles on current research and on the relationship of geoscience to social and political questions. Since 2015 it is published in magazine form and is available electronically. A hardcover edition of Eos is published once each year and contains the articles, news, and editorials from the tabloid issues. Eos accepts both display and classified advertising.

Eos (genus)

Eos is a genus of parrots belonging to the lories and lorikeets tribe of the Psittaculidae family. There are six species which are all endemic to islands of eastern Indonesia, most within very restricted ranges. They have predominantly red plumage with blue, purple or black markings. Males and females are similar in appearance.

Their habitats include forest, coconut plantations and mangroves. They gather in flowering trees to feed on nectar and pollen with their brush-tipped tongues. Fruit and insects are also eaten. They make nests in tree hollows generally high in old large trees. Threats to these parrots include habitat loss and trapping for the cagebird trade, and one species, the red-and-blue lory, is classified as endangered.

Eos (protein)

Eos (also called EosFP) is a photoactivatable fluorescent protein (PAFP).

Eos (album)

Eos is the eleventh album by Norwegian jazz guitarist Terje Rypdal recorded in 1983 and released on the ECM label.

EOS (medical imaging)

EOS is a medical imaging system whose aim is to provide frontal and lateral radiography pictures, while limiting the X-ray dose absorbed by the patient in vertical pose. The system relies on the high sensitivity of a detector ( multi-wire chamber) invented by Georges Charpak (which gave him the 1992 Nobel prize).

EOS is commercialized by the French company EOS imaging as an orthopedic application, with 3D visualization of the vertebral column and/or of the lower limbs of the patients (thanks to the application SterEOS).
