Physics-based simulation modeling and optimization of microstructural changes induced by machining and selective laser melting processes in titanium and nickel based alloys
No full textManufacturing processes may significantly affect the quality of resultant surfaces and structural integrity of the metal end products. Controlling manufacturing process induced changes to the product’s surface integrity may improve the fatigue life and overall reliability of the end product. The goal of this study is to model the phenomena that result in microstructural alterations and improve the surface integrity of the manufactured parts by utilizing physics-based process simulations and other computational methods. Two different (both conventional and advanced) manufacturing processes; i.e. machining of Titanium and Nickel-based alloys and selective laser melting of Nickel-based powder alloys are studied. 3D Finite Element (FE) process simulations are developed and experimental data that validates these process simulation models are generated to compare against predictions. Computational process modeling and optimization have been performed for machining induced microstructure that includes; i) predicting recrystallization and grain size using FE simulations and the Johnson-Mehl-Avrami-Kolmogorov (JMAK) model, ii) predicting microhardness using non-linear regression models and the Random Forests method, and iii) multi-objective machining optimization for minimizing microstructural changes. Experimental analysis and computational process modeling of selective laser melting have been also conducted including; i) microstructural analysis of grain sizes and growth directions using SEM imaging and machine learning algorithms, ii) analysis of thermal imaging for spattering, heating/cooling rates and meltpool size, iii) predicting thermal field, meltpool size, and growth directions via thermal gradients using 3D FE simulations, iv) predicting localized solidification using the Phase Field method. These computational process models and predictive models, once utilized by industry to optimize process parameters, have the ultimate potential to improve performance of products in their service life.Ph.D.Includes bibliographical referencesby Yiğit Muzaffer Ariso
A little known source of Saljuq history: ?asan-ı Yazd?’s J?mi’at-Taw?r?kh-i ?asan?
No full textUrl: http://usad.selcuk.edu.tr/usad/article/view/76Bu çalışma, Timurlu dönemi müellifi Hasan-ı Yezdî’nin Câmi‘u’t-tevârîh-i Hasenî isimli Farsça eserinin Selçuklular kısmının; tanıtımı ve değerlendirmesini ihtiva etmektedir. Müellifin hayatı ve eserlerine değinildikten sonra, eserin muhtevası, önemi ve kaynaklarından bahsedilmiş, eserin Selçuklular kısmının kaynak değeri ortaya konulmuş, ayrıca eserin dil ve imlâ hususiyetleri, nüshaları incelenmiş ve eser üzerinde yapılan çalışmaların bir değerlendirmesi yapılmıştır. Tam adı Tâcu’d-dîn Hasan b. Şihâb b. Huseyn-i Yezdî olan müellif takriben 793/1390-91 yılında doğmuş, Timurlular’dan Mîrzâ İskender b. ‘Omer Şeyh ve Mîrzâ Sultan Ebu’l-Muzaffer Muhammed Bahadır b. Baysungur’un hizmetinde bulunmuştur. Müellif Câmi‘u’t-tevârîh-i Hasenî isimli eserini telife Timurlular’dan Mîrzâ Sultan Ebu’l-Muzaffer Muhammed b. Baysungur b. Şâhruh adına 855/1451 yılında başlamışsa da, onun 855 yılı Zî’l-hicce ayında (25 Aralık 1451-22 Ocak 1452) kardeşi Ebu’l-Muzaffer Babür b. Baysungur tarafından öldürülmesi üzerine eserini Ebu’l-Muzaffer Babür b. Baysungur’a ithaf etmiştir. Müellifin hayatının bundan sonraki bölümü ve ölüm tarihi hakkında kaynaklarda herhangi bir bilgi yoktur. Câmi‘u’t-tevârîh-i Hasenî, başlangıçtan müellifin kendi zamanına kadar gelen genel bir İslâm tarihidir. Câmi?u’t-tevârîh-i Hasenî, Selçuklular ve özellikle de Sultan Sencer devri için en tafsilatlı kaynaklardan birisidir. Eserin Selçuklu tarihi için asıl önemi, müellifin, başta Sencer-nâme (veya Rezm-nâme-yi Sencerî ya da Rûz-nâme-yi Sencerî) olmak üzere, günümüze ulaşmayan bazı kaynaklardan sık sık alıntılar yapmış olmasından gelmektedir. Câmi?u’t-tevârîh-i Hasenî’nin iki yazma nüshası günümüze ulaşmıştır: 1. İran Millî Kütüphanesi (Kit?bkh?na-yi Mill?-yi ?r?n, Tahran), nr. 1330. 2. Süleymaniye Kütüphanesi (İstanbul), Fatih 4307.The present work, consisting of an introduction and two main parts, is an analytical study of the chapter on the Saljuqs in the Persian chronicle titled J?mi? at-taw?r?kh-i ?asan? (?asan?’s Compendium of Chronicles) by a Timurid author, ?asan-i Yazd?. After addressing the life and works of the author, the contents of his chronicle, its importance, and its sources (as far as they are mentioned in the text), the introduction discusses the significance of this chapter as a source on the Saljuqs. In addition, this study details linguistic and stylistic features of the text and provides in-depth analysis of its extant copies and an evaluation of its previous studies. T?j ad-D?n ?asan b. Shih?b b. ?usayn-i Yazd? was born around 793/1390-91. He served two Timurid rulers, M?rz? Iskandar b. ?Umar Shaykh and M?rz? Sul??n Mu?ammad Bah?dir b. Baysungur. The author started writing this book in 855/1451 at the order of the Timurid M?rz? Sul??n Mu?ammad b. Baysungur. In Dhu’l-?ijja 855 (25 December 1451-22 January 1452) Mu?ammad b. Baysungur was killed by his brother B?bur. The author then dedicated this work to Babur b. Baysungur. No further information exists in the sources about the author’s life thereafter or the date of his death. J?mi? at-taw?r?kh-i ?asan? can be considered a general history of Islam from its very beginning until the time of its author. This work is one of the most extensive sources on the Saljuqs, particularly about the reign of Sultan Sanjar. For this reason it deserves to be taken into account on the Seljuq historiography. The author had access to Sanjar-n?ma (or Razm-n?ma-yi Sanjar? - R?z-n?ma-yi Sanjar?). He recurrently quotes from this and some other sources that are not extant. Two copies of J?mi? at-taw?r?kh-i ?asan? have survived to our time: 1.MS. Tehran, Iran Library (Kit?bkh?na-yi Mill?-yi ?r?n), 1330. 2. MS. Istanbul, Süleymaniye Library, Fatih 4307
Naili Abdullah Pasha Defter-i Teşrifat (text-analysis)
No full textOsmanlı Devleti'nde, merâsimler ihtişâmını göstermenin en etkili yoludur. Ayrıca merâsimler, Osmanlı toplumu için önemli birer sosyal aktivitedir. Önceden belirlerlenmiş programa göre icrâ edilir ve bu program "teşrîfâtî" adı verilen protokol memuru tarafından hazırlanırdı. En üst rütbedeki protokol memuru olan teşrîfâtî, teşrîfâtla alakalı uygulamada bir sorun yaşanırsa Kalem'deki defterlere bakarak "sûret" hazırlardı. Sadrıâzama bağlı olarak çalışır ve gerektiğinde başvurulacak "teşrîfât defterlerini" hazırlardı. Çalışmamda, bu defterlerden birisi olan Nâilî Abdullah Paşa'ya ait Defter-i Teşrîfât'ın transkripsiyonu ve değerlendirmesini yaptım. Başbakanlık Osmanlı Arşivi'nde, A. d. 359 katalog numarasıyla bulunan defter –transkripsiyonunu ve tıpkı basımını yaptığım nüsha-, Sultân I. Mahmud'a sunulduğunu düşündüğüm defter olup bunun hâricinde üç adet nüshası daha bulunmaktadır. Nâilî Abdullah Paşa, teşrîfâtçılığı döneminde teşrîfât kanûnlarını derleyerek kaleme aldığı bu eser, Osmanlı târîhinde "hattlı defter" nâmıyla ün salmıştır. İhtivâ ettiği başlıca konular; bayramlaşma merâsimleri, ziyâfetler, elçi kabulleri, dîvân-ı hümâyûna dâir kanûnlar, hil'at ve kürk ilbâsı, cenâze ve düğün törenleri, ordu ve donanma ile alakalı merâsimlerdir. Üslûbu, diğer teşrîfat defterlerinden biraz farklı olup yazar, aktardığı kural ve kaideleri, muhtelif tarihlerde icra edilen merasimlerden örnekler vererek anlatımı kuvvetlendirmiştir. Bu defter, Osmanlı devlet protokolünü çalışanlar için mühim bir kaynak olmasıının yanı sıra, Osmanlı tarihinin diğer alanlarında çalışma yapanlar için de mühim bir kaynaktır.In the Ottoman Empire, ceremonies were the most effective way of displaying grandeur. In addition, ceremonies were an important social activity for the Ottoman society. They were carried out according to a pre-determined program and was prepared by a protocol official. If a problem happens regarding the protocol, the highest ranking protocol official would prepare "sûret" in accordance to the books at Office. He would work connected to the Grand Vizier and prepared the "Protocol registries" which would be referred when needed. In mine study, the transcription and evaluation of one of these books, Nâilî Abdullah Pasha's Protocol book, was made. At the Ottoman Prime Ministry Archives, the notebook which could be found with A. d. 359 catalog number, is the notebook that is believed to be a belonging of Sultan I. Mahmut, and it also has three more copies. This work, which Nâilî Abdullah Pasha wrote by compiling the laws of protocol, became known with the name of "Hattlı defter" in the Ottoman history. Primary subject included being; ceremony of greetings in festivals, feasts, acceptance of an envoy, laws concerning the council (Divan-ı Hümayun), funeral and wedding ceremonies, army and navy ceremonies. The style is slightly different from other protocol books, and the author, the rules and bases, have strengthened the narrative by giving examples of the cerenomies performed in various dates. This Notebook is a very important sourve both for the people who study Ottoman state protocols and for the researchers of the other fields of Ottoman history
A Pioneering LISP Framework for Diachronic Urban Analysis
No full textThis paper describes a pioneering methodological innovation bridging computational tools and traditional urban morphology by introducing a LISP-based scripting framework for morphological and typological analysis of historical city formation. Developed in 2020 as part of the author Elham K. Hassani’s Ph.D. dissertation at Sapienza University of Rome and grounded in the Italian school of urban morphology—particularly the work of Caniggia and Muratori—it provides a replicable method to read and classify urban transformations over time. This was the first application of LISP programming to automate identifying and categorizing urban elements—plot structure, route alignment, and building typology—across multiple historical phases. The methodology integrates qualitative morphological principles with quantitative computational processes, enabling a deeper understanding of urban form evolution and building type variation within a diachronic framework. Using Kashan, a traditional Iranian city, as a case study, the method reconstructs historical phases of urban growth, revealing their spatial logic, typological patterns, and morphological shifts. This dual-level analysis moves the field beyond static visual mapping toward rule-based interpretive systems, contributing to current efforts to apply AI to resilient city-making. Its significance is shown by its integration into Sapienza’s curriculum
Value creation: a tourism mobilities perspective
No full textThis chapter explores issues relating to value creation and co-creation during the tourism mobilities component of holiday travel. It first suggests a number of factors that influence the value creation process in the tourism mobilities sector. The chapter then decomposes the typical tourist journey into the stages of travel and identifies the opportunities that may occur for value creation and co-creation during each stage. This is followed by an analysis of several actual encounters to explore how individual stages of travel generate opportunities for value creation. The first case study is based on an overnight road trip undertaken by the author and his son. The second describes opportunities for interacting with other passengers during a day tour in Helsinki

The Alliance between Mengu-Timur and Abaga: The Problem of Sources Interpretation and Translation of Persian and Turkic Terms in Arabic Texts (on the example of “Collection of Materials Relating to the Golden Horde History. Volume I. Excerpts from the Arabic Writings” composed by V.G. Tiesenhausen) »
No full textThe Turkish author Ihsan Fazlioğlu presents to attention of readers the second part of the article “A Masterpiece of Computational Mathematics” (“et-Tuhfe fî ilmi’l-hisâb”). The author of this article presents the first example of an established scientific activity in the Golden Horde, which began before Janibek khan, during the reign of Uzbek khan. The work written in the Golden Horde on a mathematical topic occupies a special place because of the information contained therein. This treatise shows that the scientific activity in the Golden Horde, which began with the conversion to Islam, brought results in a short time and laid the foundations for “breakthroug” during the reign of Janibek khan.
The author examines this composition from a historical perspective. The Computational book “et-Tuhfe fî ilmi’l-hisâb”, whose author is unknown, was handed during the reign of Uzbek Khan (1313–1342) to the ruler of the Crimean ulus of the Golden Horde Ebul-Muzaffer Giyaseddin Tuluktemir bey. After mentioning the distinguishing features of the work, the author pays particular attention to the definition of numbers, which is attributed to Muhammad b. Musa al-Khwarizmi and which, at the moment, is not recorded elsewhere. The author disputes the capacity for understanding of the evidence used in the calculation, surveying, and algebra, and will consider definitions with respect to the theory of numbers. Further, the author will analyze the formula of approximate values of square and cube roots of irrational numbers proposed by Muhammad al-Khwarizmi, Abdulkadir al-Baghdadi, and the teacher of the author, Saduruddin al-Farazi.
This part examines the author of the work and features of his age as well as the scientific environment that contributed to the writing of the “et-Tuhfe fî ilmi’l-hisâb”. The article presents the contents of the work and familiarizes the reader with the scientists and their works, which are referenced by the author
