The Surrender Software
Scientific image rendering for space scenes with the SurRender software Scientific image rendering for space scenes with the SurRender software R. Brochard, J. Lebreton*, C. Robin, K. Kanani, G. Jonniaux, A. Masson, N. Despré, A. Berjaoui Airbus Defence and Space, 31 rue des Cosmonautes, 31402 Toulouse Cedex, France [email protected] *Corresponding Author Abstract The autonomy of spacecrafts can advantageously be enhanced by vision-based navigation (VBN) techniques. Applications range from manoeuvers around Solar System objects and landing on planetary surfaces, to in -orbit servicing or space debris removal, and even ground imaging. The development and validation of VBN algorithms for space exploration missions relies on the availability of physically accurate relevant images. Yet archival data from past missions can rarely serve this purpose and acquiring new data is often costly. Airbus has developed the image rendering software SurRender, which addresses the specific challenges of realistic image simulation with high level of representativeness for space scenes. In this paper we introduce the software SurRender and how its unique capabilities have proved successful for a variety of applications. Images are rendered by raytracing, which implements the physical principles of geometrical light propagation. Images are rendered in physical units using a macroscopic instrument model and scene objects reflectance functions. It is specially optimized for space scenes, with huge distances between objects and scenes up to Solar System size. Raytracing conveniently tackles some important effects for VBN algorithms: image quality, eclipses, secondary illumination, subpixel limb imaging, etc. From a user standpoint, a simulation is easily setup using the available interfaces (MATLAB/Simulink, Python, and more) by specifying the position of the bodies (Sun, planets, satellites, …) over time, complex 3D shapes and material surface properties, before positioning the camera. -

Between 1914 and 1918, over 2.5 million civilians lost their lives on the battlefields or to hunger and disease. From among those, over one million Armenians were targets of a systematic genocidal campaign organized by the Ottoman state. It was in the aftermath of this catastrophe that University of Michigan Professor of Archaeology Francis Willey Kelsey (1858–1927) and U-M staff photographer George Robert Swain (1866–1947) em-barked on an expedition to the region, the purpose of which was to collect ancient Christian manuscripts destined to disappear in the postwar chaos. -

The Concept of Creating and Regulating Time in Vedic Ritual the Concept of Creating and Regulating Time in Vedic Ritual
The concept of creating and regulating time in vedic ritual The Concept of Creating And Regulating Time In Vedic Ritual Maitreyee Deshpande Maitreyee Deshpande, Department of Sanskrit, University of Pune, Pune - 411 007, Maharashtra Time is an important factor that governs the life of man. Numerous speculations have been put forth by various thinkers about ‘time’. These speculations are based upon numerous philosophical systems. ‘Time’ is interpreted differently by a Physicist as compared to an Archaeologist or even a Philosopher. Thus attempts have been made in each field to interpret and understand this very important factor. They all interpret time according to their Weltanschauung. There also have been numerous theories about the creation of time. In this paper an effort is made to show how time could be created and regulated with the help of vedic rituals. Time is often accepted to be created by Prajaapati by many ritual texts. Shatapatha Braahmana (S B) (XI.1.6.12ff) explains the two terms samvatsara and prajaapati. It says Prajaapati created the deities and he thought that he had obtained everything (atsaarisham). Therefore he became sarvatsara, which is doubtless the same as samvatsara. Also there are four syllables in the word ‘samvatsara’ as well as in the word ‘prajaapati’. Therefore samvatsara is the image of Prajaapati. (S B) (VI.1.2.18), while referring to the creation of the year, says that Prajaapati who became relaxed is the year, and his five bodily parts too became relaxed and they are the seasons in a year. In (SB) (XI.1.6.1ff), regarding the creation of seasons by Prajaapati, we read as follows : In the beginning there was water. -
Ethiopian Calendar from Wikipedia, the Free Encyclopedia
Ethiopian calendar From Wikipedia, the free encyclopedia The Ethiopian calendar (Amharic: የኢትዮጵያ ዘመን አቆጣጠር?; yä'Ityoṗṗya zämän aḳoṭaṭär) is the principal calendar used in Ethiopia and also serves as the liturgical year for Christians in Eritrea and Ethiopia belonging to the Orthodox Tewahedo Churches, Eastern Catholic Churches and Coptic Orthodox Church of Alexandria. It is a solar calendar which in turn derives from the Egyptian Calendar, but like the Julian Calendar, it adds a leap day every four years without exception, and begins the year on August 29th or August 30th in the Julian Calendar. A gap of 7–8 years between the Ethiopian and Gregorian Calendars results from an alternate calculation in determining the date of the Annunciation. Like the Coptic calendar, the Ethiopic calendar has 12 months of 30 days plus 5 or 6 epagomenal days, which comprise a thirteenth month. The Ethiopian months begin on the same days as those of the Coptic calendar, but their names are in Ge'ez. The 6th epagomenal day is added every 4 years, without exception, on August 29 of the Julian calendar, 6 months before the corresponding Julian leap day. Thus the first day of the Ethiopian year, 1 Mäskäräm, for years between 1900 and 2099 (inclusive), is usually September 11 (Gregorian). It, however, falls on September 12 in years before the Gregorian leap year. In the Gregorian Calendar Year 2015; the Ethiopian Calendar Year 2008 began on the 12th September (rather than the 11th of September) on account of this additional epagomenal day occurring every 4 years.

The Southesk and Other Rune Prime-Staves Or Scandinavian Wooden Calendars
VII. THE SOUTHESK AND OTHER RUNE PRIME-STAVES OR SCANDINAVIAN WOODEN CALENDARS. BY H. F. MORLAND SIMPSON, M.A., F.S.A. SCOT. Two summers ago the Earl of Southesk showed me a walking-stick finely carved with runes and symbols, and permitted me to take a rubbing of an object strange but interesting. It was said to have belonged to a Russian Count, but nothing more was known of its previous history. The staff (fig. 1) is some 43 inches long, round, and tapering, with a brass ferrule and iron spike. The head is made of a fine pale blue-grey agate mounted in a crown-shaped setting of silver niello, of modern workmanship and Russian style, according to Lord Southesk, who is expert in gems. Below this the staff is pierced for a tassel, and the hole ornamented with a star in the same style. The wood is smooth, and fine in grain, stained or darkened by age. The inscription is 37 inch.es long, in two columns, each consisting of a double row of runes, with symbols between. The runes are spaced at irregular intervals by a sun and moon enclosed in circles (v. fig. 1, No. 1, &c.). The lower part, 5£ inches long, contains several systems of dashed runes, then quite unknown to me, and specially difficult to solve. The upper row of runes in each column is made up of the first seven S» 5' 52-Si- §>. 54. S5S*-S1 99. 59. <»0. rf,. v^l^ •'(r^rD^^rpp^t+tiiWi 2 13 >3. -

CHRISTIAN INSCRIPTIONS FROM EGYPT AND NUBIA 6 (2018) Alain Delattre Université Libre de Bruxelles, Jitse Dijkstra University of Ottawa, and Jacques van der Vliet Leiden University/Radboud University Nijmegen Abstract. — Sixth installment of an annual overview of published inscriptions in Greek and Coptic from Christian Egypt and Nubia. The sixth issue of our epigraphical bulletin is devoted to inscriptions published in 2018, to which are added one left-over item from 2015 (70) and some items from 2017 (3, 29, 56, 57–68, 69) that came too late to our attention to be included in the previous bulletin. 1. Egypt and Nubia. Christian epigraphy. J. van der Vliet, “Epigra- phy,” in K.J. Torjesen and G. Gabra (eds.), Claremont Coptic Encyclopedia (2018), available online at http://ccdl.libraries.claremont.edu/cdm/singleitem/ collection/cce/id/2161. Short survey of the discipline, with useful biblio- graphical references that provide a starting point for further research. 2. Egypt and Nubia. Christian epigraphy. J. van der Vliet, The Chris- tian Epigraphy of Egypt and Nubia (London 2018) presents 31 studies con- tributed by a major specialist in the field over almost two decades (1998– 2015). The volume collects a large number of studies published in a wide variety of places; four studies have been translated from French, and several photos of monuments have been replaced by new ones (e.g. Figs. 19.1 and 2), although they are not printed on glossy paper, which means that they are not always as sharp as one would like them to be. Eleven studies are co-authored, showing the collaborative spirit of the author.
