No full textScan-Based Immersed Isogeometric Flow Analysis
No full textThis chapter reviews the work conducted by our team on scan-based immersed isogeometric analysis for flow problems. To leverage the advantageous properties of isogeometric analysis on complex scan-based domains, various innovations have been made: (i) A spline-based segmentation strategy has been developed to extract a geometry suitable for immersed analysis directly from scan data; (ii) A stabilized equal-order velocity-pressure formulation for the Stokes problem has been proposed to attain stable results on immersed domains; (iii) An adaptive integration quadrature procedure has been developed to improve computational efficiency; (iv) A mesh refinement strategy has been developed to capture small features at a priori unknown locations, without drastically increasing the computational cost of the scan-based analysis workflow. We review the key ideas behind each of these innovations, and illustrate these using a selection of simulation results from our work. A patient-specific scan-based analysis case is reproduced to illustrate how these innovations enable the simulation of flow problems on complex scan data.</p
Comparison of Reservoir Simulation Techniques for Gas Reservoirs: Semi-Analytical Tank Flow Model Approach versus Finite Volume Solutions
No full textComparison of Reservoir Simulation Techniques for Gas Reservoirs: Semi-Analytical Tank Flow Model Approach versus Finite Volume SolutionsMehmet Onur Doğan a, Tayfun Jamalbayli* a, Mahammad Jamalbayov ba Middle East Technical University, Turkey b SOCAR "OilGasScientificResearchProject" Institute, Azerbaijan * Corresponding author: [email protected]: Numerical Model Development; Reservoir Simulation; Reservoir Modeling; Gas Condensate Reservoirs; Reservoir EngineeringThis research introduces a hybrid approach for reservoir simulation and explores its practical utility within the context of gas condensate reservoirs. The study assesses the strengths and weaknesses of this approach by comparing it to the conventional two-phase gas condensate model that employs the finite volume method. The methodology utilizes material balance equations to compute the average reservoir pressure and saturation. These computed values are subsequently applied across the reservoir using an analytical flow model, while taking into consideration well placements. This results in the development of a semi-analytical simulation approach. In addition, the finite volume model is also created as a benchmark model for comparative purposes, including IMPES and Fully Implicit solutions. The validity of the finite volume model is established through a comparison with Eclipse simulation software. The proposed simulation approach calculates pressure and saturation distributions that exhibit notable deviations from the results of the finite volume method, particularly struggling to accurately represent the region near the wellbore in terms of saturation. However, it excels in terms of computational efficiency and outperforms traditional methods in terms of speed. To enhance this approach, a future recommendation involves integrating the pressure distribution derived from the hybrid method with traditional saturation calculations. This integration has the potential to rectify discrepancies in saturation distribution while retaining the method's speed advantages. In summary, the hybrid reservoir simulation method presents a promising innovation for reservoir simulation techniques. The outcomes of the study provide a pathway to address these limitations, ultimately paving the way for a more efficient reservoir simulation tool

Regional Lydian pottery at Daskyleion: testing stylistic classification by chemical analysis
No full textThis paper presents the results of an interdisciplinary study of Lydian pottery excavated at Daskyleion between 1988 and 2002. Before becoming the satrapal centre of Hellespontine Phrygia in the Achaemenid period, to judge by the historical and archaeological evidence, Daskyleion had close interrelations with the Lydian kingdom. Previous stylistic and macroscopic fabric studies of Lydian pottery from Daskyleion have shown that as well as items produced in the Lydian capital of Sardis, ceramics may also have been imported from other production centres in the region of Greater Lydia (GÜrtekin-Demir 2002). New chemical analysis by neutron activation (NAA) of 31 samples from Daskyleion presented here confirms this suggestion. We determined four chemical provenance groups of Lydian pottery, each of them defined by an element pattern which is distinct from the pottery made in Sardis. Although these four provenance groups cannot be located at present due to the lack of reference data from potential Lydian-style ceramic production centres in Anatolia, they prove that other production centres existed outside Sardis. Daskyleion may have been one of those. © 2022 The Author(s)

Danimarka türk toplumunun sosyal entegrasyonu ve din
No full textMarmara Üniversitesi Sosyal Bilimler Enstitüsü Doktora Tez Özeti Tezin Başlığı: Danimarka Türk Toplumunun Sosyal Entegrasyonu ve Din Bu tez çalışması ile Danimarka’da yaşayan Türklerin, hâkim topluma entegrasyonu ile din arasındaki ilişki araştırılmıştır. Konunun anlaşılır olması için gerekli araçlar olan göç ve kültürlerarası karşılaşmalar ile ilgili kavramlar incelenmiş, entegrasyonu etkilemesi itibariyle, araştırmalar ve istatistiklerin sağladığı veriler ışığında Danimarka Türk toplumu ile Danimarka toplumunun sosyo-kültürel profilleri tasvir edilmiş, Danimarka devletinin entegrasyon ile ilgili düzenlemeleri ve Danimarka toplumunda konu ile irtibatlı olarak yaşanan tartışmalar değerlendirilmiştir. Ardından Türklerin entegrasyonunu belirleyen parametreler ile bağımsız değişkenler arasındaki ilişki test edilmiş, katılımcıların toplam dindarlık puanı ve toplam entegrasyon puanı tespit hesaplanarak din ve entegrasyon arasındaki ilişkinin varlığı ve yönü araştırılmıştır. Bütün bu veriler ve bilgiler bir arada değerlendirildiğinde entegrasyonun, hem hâkim toplum ve azınlık gruplar olmak üzere çok boyutlu, hem de çok nedenli olduğu ortaya çıkmaktadır. Din ile entegrasyon ilişkisinin de tek nedenli olarak açıklanamayacağı ve bu ilişkinin yönünü ve düzeyini belirleyen birçok unsurun bir arada değerlendirilmesi gerektiği anlaşılmaktadır. Sonuç itibariyle Danimarka’da yaşayan Türklerin entegrasyon problemlerinin çok yaygın ve fazla olmadığı ve bu entegrasyon problemlerinde de dinden ziyade dil becerisi, eğitim, istihdam sorunları, Danimarkalılarla ilişkiler ile sosyo-kültürel mesafe ve Danimarka toplumunda yine çok yaygın olmasa da ayrımcılığın söz konusu olduğu durumların mevcudiyeti gibi etkenlerin rol oynadığı görülmektedir. uluslararası göç, göçmen, sosyal entegrasyon, asimilasyon, çokkültürlülük, din ve entegrasyon ilişkisi, Danimarka.

With regard to effected integration, in light of data which researches and statistics provided, Denmark Turkish society and Denmark’s social cultural profiles are described. Organization of Denmark state concerning integration and debates taking place concerning about the topic in Denmark society have been evaluated. Later on parameters determining integration of Turks and relationship between independent variables are tested. Calculating the participant’s total religiosity score and total integration score existence and direction of relation between integration and religion have been investigated. By evaluation of all these data and informations together integration, is emerging both policausal and multidimensions in term of both majority society and minority groups it has been understanding that the relationship between religion and integration can not be explained as monocausal and the several elements determining the direction and the level of this relationship should be evaluated all together. As a consequence the integration problems of Turks living in Denmark aren’t so prevailed and much and in this integration problems it have been seen the role of factors such as language ability, education, employment problems, relations with Danish, social-cultural distance and existant of conditions of discrimination which even do is not so prevailed in Denmark society more than religion itself. Key words: international migration, immigrant, social integration, assimilation, multiculturalism, relationship between integration and religion, Denmark
Peer Review Process in Turkey for Journals Regarding Social and Human Sciences: A Study from the Perspectives of Author, Peer Reviewer and Editor
No full textThe main purpose of this study is to examine the peer review process in Turkey, from the perspectives of authors, peer reviewers and editors of social and human sciences. Thus, the attitudes and behaviors of the parties participated in that process and of which roles are usually overlapped (author, peer reviewer and editor) and the problems they experienced can be determined at first hand and valuable data that can contribute to enhance in qualification and activation of the process and/or in questioning of the process. A web based survey is conducted to achieve this purpose. The survey results reveal that the authors, the peer reviewers and the editors support the peer review system in social and human sciences, in principle. A very large majority of the respondents agreed or strongly agreed with the statement, “There is no control in scientific communication without formal peer review.” On the contrary only three percent of the total respondents agreed or strongly agreed with the statement, “Peer review system is useless.” Furthermore, approximately one-fourth of the respondents agreed or strongly agreed with the statement, “Current peer review system is the best we could do.” These findings suggest that the majority regard peer review as a mechanism providing control on quality but the current peer review system is not the best we could do and improvements can be made to make it better. Based on these and other survey findings, the authors of the article make suggestions for improvement
