In its spirit, scope and style, it is a sequel to my previous book, G. Korvin, “Fractal Models in the Earth Sciences” (Amsterdam: Elsevier, 1992), that was well received at the time it appeared, and has introduced generations of Earth Scientists to modeling Earth formations and processes by fractals. Two years ago, I was asked by the editors of Springer’s Encyclopedia of Mathematical Geosciences to contribute a few chapters to this important reference book, and when working on one of them, “Statistical Rock Physics”, I realized that this new discipline has reached such a matu- rity in recent years that it would deserve a self-consistent, full-fledged, monographic treatment. I am grateful to Profs. Fritz Agterberg and Daya Sagar for recommending my book for publication, and to Springer Nature, especially to Ms. Anette Buet- tner, Ms. Hemavathy Manivannan, and Ms. Deepa Varadharajan, for espousing this idea and for helping me through the arduous process of book writing, editing and processing. Statistical Rock Physics is a part of Rock Physics (Petrophysics). Its concepts, methods and techniques have been borrowed from Stochastic and Integral Geometry and Statistical Physics. In this new science, one describes the interior geometry of rocks; derives their effective physical properties based on their random composi- tion and the random arrangement of their constituents; and builds models to simu- late the past geological processes that had formed the rock. Most techniques that will be discussed belong to the toolbox of the “Digital Rock Physics” (DRP) tech- nology of Core Analysis. My aim has been to help readers to understand the claims and published results of these powerful new methods, and—most importantly—to creatively apply stochastic geometry and statistical physics to their own research tasks. My own understanding of these tools had matured by incorporating them, and teaching them for more than two decades in a heuristically simplified but mathemat- ically precise form, in my Geophysical Inversion, Solid Earth Geophysics, Reservoir Characterization, Well Logging and other courses at the King Fahd University of Petroleum and Minerals (Dhahran, Kingdom of Saudi Arabia) LA - English DB - MTMT ER - TY - JOUR AU - Korvin, Gábor TI - Muḥammad’s Jug: Arabic Motifs in Borges’s Texts JF - ARABIST: BUDAPEST STUDIES IN ARABIC J2 - ARABIST VL - 46 PY - 2024 SP - 103 EP - 147 PG - 45 SN - 0239-1619 UR - https://m2.mtmt.hu/api/publication/35182307 ID - 35182307 AB - In this study I discuss twenty-three Arabic motifs in Borges’s texts and trace them back to their most likely sources. Borges did not know Arabic and gained his knowledge of the Orient from secondary sources, books by Burton, Lane, Asín Palacios, and others. In many cases Borges playfully changed these Arabic motifs, or invented new ones. In the rare occasions when he gave his sources, these were as fantastic as the stories themselves: references to non-existing tomes by non- existing scholars, to an odd book of Burton (instead of the correct one by Lane), or to an out-of-context citation from Gibbon. I succeeded in locating the sources of most of these motifs and proved for a few others that they are inventions of Borges. I could not find the source of one poem. For one motif (“Iskander’s mirror”) I could only show that it is well-documented in Oriental literature, but I could not find any likely source where Borges could have learned about it.

This paper studies the accuracy of these transliterations, by comparing 152 poems (2734 lines) from seven poets, including Jaipur-based Urdu poet Parsā Kaūsarī Jaipūri (1922-1999) whose hitherto unknown Urdu manuscript containing his Collected Poems is introduced and described. Word- by-word comparison detected that in 113 out of 2734 lines the original and transliterated texts slightly differed. As the Hindi and Urdu languages are almost identical in their vocabulary and grammar, rewriting an Urdu nasta‘lÊq text in to Dēvanāgarī is a special case of domestication , that is a strategy of making the target text closely conform to the pronunciation, orthography and grammar of the Hindi language. For the lay reader such “Urdu-in-Dēvanāgarī” reproductions of the Urdu ghazals are useful, satisfactory and preserve their esthetic value, but to avoid loss of information from the source text, it is recommended that definitive, scientific editions of Urdu ghazals should always be published in both scripts en face, with the rare Urdu words explained in footnotes.

It is a method to estimate the Hurst exponent H, which describes how the rescaled range of a random process X grows with time.

The term “digital” is meant in contrast with the other major type of filters, the analog filter, which is used during signal-recording and is typically realized by an electronic circuit operating on continuous-time analog signals.
