A Comparative Analysis of Skyscraper Design Characteristics in the Middle East, Asia, and North America
(Hapres Limited, 2025) Ilgın, H.; Aslantamer, Ö.
The proliferation of skyscrapers in rapidly urbanizing regions necessitates a comparative understanding of architectural and structural design strategies. The Middle East, Asia, and North America have emerged as dominant centers of high-rise development, each influenced by unique environmental, cultural, and economic conditions. This study employs a case study approach, analyzing 133 skyscrapers (≥300 m) using qualitative and quantitative metrics. The analysis focuses on core typology, structural systems, materials, and architectural form, based on data extracted from the Council on Tall Buildings and Urban Habitat (CTBUH) database. Findings reveal regional distinctions: Asian skyscrapers favor tapered and composite designs with outriggered frame systems; Middle Eastern towers emphasize prismatic forms using concrete; and North American high-rises balance setback and prismatic forms with concrete and shear-frame systems. A central core layout dominates all regions, driven by efficiency and safety considerations. These insights offer valuable benchmarks for architects, engineers, and urban planners aiming to optimize skyscraper design in dense urban contexts. These insights offer valuable benchmarks for architects, engineers, and urban planners aiming to optimize high-rise design in dense urban contexts. © 2025 Elsevier B.V., All rights reserved.

Advanced Control of Eleven Level Modular Converter Connected To the Power Grid Via Hvdc Transmission Line
(Transilvania University of Brasov 1, 2023) Koulali,M.; Negadi,K.; Berkani,A.; Aimer,A.F.; Marignetti,F.; Bullent Ertan,H.
The implementation of an advanced control system for an eleven-level modular converter connected to the power grid via an HVDC transmission line is discussed in this study. The control system's goal is to maintain stable and dependable converter operation under a variety of operating circumstances and grid disruptions. The control system includes a number of control loops, including feedforward compensation loops for voltage, current, and power. In order to share active and reactive power between parallel-connected converters, a droop control approach is also used. Through simulation studies for various scenarios, such as changes in grid voltage and frequency, load variations, and converter faults, the control system is created and validated. The findings show that the suggested control system is capable of effectively controlling the converter's output voltage and power, suppressing harmonic distortion, and ensuring the converter's stable and dependable functioning in the face of grid disruptions. Therefore, the enhanced control method can enhance the HVDC transmission system's performance and dependability, resulting in the creation of a more effective and intelligent power grid. © 2023 IEEE.

Alternative Solutions for Urban Housing: the Case of Batikent Settlement, Ankara, Turkey
(Wit Press, 2017) Atici, Melike
The present study is an effort to remember and reveal the potentials of Batikent settlement which was realized in the west part of the capital city of Turkey, Ankara in 1980s. In the period after 2nd World War, big cities in Turkey, like many other countries, entered in the process of rapid urbanization under the influence of mechanization in agriculture and migration from rural to urban areas. Increase in the population of cities and scarcity of shelter brought with the emergence of squatter areas. Batikent settlement was developed as a flagship solution to this housing problem and established a precedent with its model of implementation for future urban cohabitations. Batikent, as a new settlement area, was initiated by Municipality of Ankara and developed a never-before-seen operational model with three main collaborators: central government, municipality and association of housing cooperatives (Kent-Koop). Separation of roles - such as passing fiscal and housing laws, providing financial support, expropriation of land, constructing technical infrastructure, establishing municipal and commercial services, preparing master plan and designing site and house plans - through these collaborators provided this new mass development project with effective, practical and economical solutions. This study will focus on how Batikent was developed as a platform for innovation with the operational model based on dialogue between different parties. Collection of plans from master plans to layouts of apartments, meeting notes and feasibility studies documented and published by Kent-Koop will be used in this study to achieve a better understanding of the planning process of this exemplary quarter.
An Analysis of a Special Talent Examination and the Matter of Quality;
(T.C. Milli Egitim Bakanligi, 2017) Ünver,E.; Ünver, Erdem; Ünver, Erdem; Textile and Fashion Design; Textile and Fashion Design
Although there is an evaluation system, prepared by The Council of Higher Education, concerning special talent examinations, there are several differences in application. Changing grade rates, accepted in the current program, most universities' preselection systems, and some universities' enrolling all students or considering only special talent examinations are some of the basic differences. Data, gained through the analysis of the special talent examination, held at AU, a private university, reveal the matter of quality clearly. In the two dimensional matrix analysis of data in the 2015-2016 Academic Year special talent examination, it has been discovered that the results are parallel to the previous years' grades, no precautions have been taken to solve the quality matter and the same problem has been experienced in most private universities which sustain themselves with student tuitions, and have been holding ranking examinations instead of special talent examinations to fill their quota. The aim of this study is to provide the reader with numerical data for the analysis of the talent examination, in which The Council of Higher Education's evaluation system has been applied, by means of such scores of the candidates as the University Entrance Examination Grade, High School Grade Point Average, Special Talent Examination Grade, and the Placement Grade. The results show that students who do not have the competency required by the field of art and who are not able to develop desired behaviours in the field are enrolled at fine arts or art education departments.

Anxiety and Depression After Cesarean: Non-Pharmacological Evidence Based Practices;
(Dokuz Eylul University, 2022) Terzioğlu,F.; Gençbaş,D.; Boztepe,H.; Doğu,N.; Akdeniz,C.; Yüceer,B.
The purpose of this review is to examine the non-pharmacological evidence-based practices of anxiety and depression after a cesarean section delivery. Postpartum anxiety and depression have increased in the last decade, the rates of postpartum depression are around 13% worldwide. In the postpartum period, women may experience anxiety and depression due to the operation they have undergone; such as being in an unfamiliar environment, facing new technological equipment and encounters with the medical teams, the post-operative pain, the new roles women undertake as mothers. One of the factors that increase anxiety and depression in the postpartum period is the type of delivery. In Turkey, the rate of cesarean delivery is comparatively high, which is approximately 52%. Anxiety and depression after cesarean section develop due to fear and concern such as the complications that may occur during and after the mother's anesthesia, the possibility delaying breastfeeding her baby, and experiencing pain. Non-pharmacological evidence-based applications such as reiki, acupressure, hand and foot massage, yoga, reflexology, aromatherapy, skin to skin care, nursing care protocols were found to be effective in studies conducted to reduce anxiety and depression after cesarean-section. Nurses who have critical roles and responsibilities in pre-and post-cesarean care practices are recommended to include these evidence-based non-pharmacological practices in routine care practices. © 2022, Dokuz Eylul University.

Architectural Competitions in a Maturing Milieu: Mapping the Agency of Actors
(Springer, 2023) Bican,N.B.; Guneri,G.
The last three decades, overwhelmed with capitalist competitive urbanisms, have witnessed a renewal of interest in the relationship between urban form and “the right to just cities,” mainly upon discussions over diversity and participation. The same period also witnessed the triumph of architectural competitions both as effectual tools of agonism and as potential means of cultivating participatory cultures in the production of urban space. Recent discussions, hereof, suggest that competitions’ agonistic vocations counteracted the pluralist. To solidify this critical rhetoric, withal, there is insufficient research on power dynamics, structures, and implications of competitions. Herein, this study, in its broadest sense, investigates the potency of architectural competitions in allocating spatial, social, political, and economic resources and capacities. The work critically and creatively maps the dynamics and structures of competitions and further testifies (potential) agencies of multifarious actors among these, specifically delving into the emergent local governance structures of two cities from a developing country: Istanbul and Ankara. With divergent spatial development histories and trajectories, the two become complementary cases, novel local governance models of which fundamentally operationalize architectural competitions as means of commoning and register a radical paradigm shift. From a critical and comparative framework, the research reviews literature and relevant data and relies on semi-structured interviews with local government officials, city councilors, competition organizers, jurors, and critics. The findings highlight repressive processual components and potential means and methods of cultivating public agency and a solid and longstanding tradition of public participation in urban space production via architectural competitions. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

Assessing the Role of Style in Literary Translation
(Ovidius University, 2017) Aksoy,N.B.
Literary translation and its characteristics have been a point of attraction in literary and academic circles for so many years. It has been generally accepted that since style is the most distinguishing element of a literary text, its recreation in translation is of utmost importance. Hence, in order to understand the hows and whys of literary translation, a sound and definite description of what a literary text is, is needed as a first step. A source text of literature does not have the same qualities as those of its translated version since the translation carries in itself the shadows of both the source and the target linguistic and literary elements. In order to overcome the challenges of literary translation then, it is a prerequisite for the translator to be a very good reader of literature in order to fully grasp all the literary, stylistic and cultural qualities of the source text, with all its intended meanings and effects. © 2017 Ovidius University.

Asymmetric Effects of Credit Growth on the Current Account Balance: Panel Data Evidence
(Springer Science and Business Media B.V., 2019) Ekinci,M.F.; Omay,T.
Expanding current account balances (both surpluses and deficits) prior to the global economic crisis dominated academic and policy debates over the past decade. Understanding the role of credit growth on the current account balance has become a priority particularly with the rebalancing experience in the post-crisis period. In this study, we adopt a comprehensive framework by constructing an empirical model that accommodates asymmetric adjustments of current account balance to the changes in the total and household credit growth. We consider the asymmetric effects in two dimensions. When we discriminate between credit expansion and contraction episodes, our results show that credit growth has a stronger negative impact on the current account balance during credit expansion periods. Furthermore, negative effects of total and household credit growth on the current account balance are more pronounced during current account deficit episodes. © 2019, Springer Nature Switzerland AG.

Automorphisms of the mapping class group of a nonorientable surface
(Springer, 2017) Atalan, Ferihe; Szepietowski, Blazej
Let S be a nonorientable surface of genus g >= 5 with n >= 0 punctures, and Mod(S) its mapping class group. We define the complexity of S to be the maximum rank of a free abelian subgroup of Mod(S). Suppose that S-1 and S-2 are two such surfaces of the same complexity. We prove that every isomorphism Mod(S-1) -> Mod(S-2) is induced by a diffeomorphism S-1 -> S-2. This is an analogue of Ivanov's theorem on automorphisms of the mapping class groups of an orientable surface, and also an extension and improvement of the first author's previous result.

Bacterial Microbiota and Chemical Properties of Turkish Tarhana
(Slovak Univ Agriculture Nitra, 2022) Omeroglu, Esra Ersoy; Can, Oezge; Temiz, Sevval Nur; Al, Rabia; Altunbas, Osman; Soyucok, Ali; Sudagidan, Mert
Tarhana is one of the traditional Turkish fermented food and it is served as a soup. In this study, bacterial microbiota and chemical properties (acidity, salt, and moisture content) of tarhana samples (n=96) were examined. The metagenomic analysis revealed that Firmicutes were the dominant phylum and Bacillaceae, Enterococcaceae, Paenibacillaceae, Enterobacteriaceae, and Clostridiaceae were the dominant bacterial families. In the samples, Bacillus, Enterococcus, and Paenibacillus were mostly identified at the genus level. Alpha diversity and evenness showed that sample 30 had the highest diversity collected from Izmir. Principal Coordinate Analysis was used to identify relationships of samples at different taxonomic levels and it was found that most of the samples were closely related at the phylum level. Chemical analysis indicated that the acidity of tarhana samples varied between 5.00% and 42.5%, moisture contents were 4.39- 18.66% and salt values were from 0.32% to 6.64%. The results of this study extensively demonstrated the chemical properties and the dominant bacterial communities present in tarhana samples collected from different parts of Turkiye.
A Bakhtinian Perspective for the Chronotopic Evaluation of Symbols in “hills Like White Elephants” by Ernest Hemingway
(Ovidius University, 2024) Aksoy, N.B.
This paper discusses the metaphoric and spatial representations in the short story “Hills Like White Elephants” from the perspective of Bakhtin’s concept of chronotope. Bakhtin explains the concept of chronotope in literary texts as the intersection of space and time configured either in abstract or concrete entities, represented by symbols and metaphors or real-time objects and spaces. In the story, an unmarried pregnant girl and the child's father are portrayed at a train station discussing their and their unborn child's future. The story reflects the qualities of a typical Hemingway style, the “iceberg theory” he favours in storytelling. The train station in the story is located at the intersection of railway lines in the direction of Barcelona and Madrid, and this location becomes a symbol of the decision the couple will make at that particular historical time about keeping or aborting the baby. The station is situated between a patch of dry brown land and long and white hills across the fertile valley of the Ebro river, where the characters are about to decide whether to go back to their old, barren life or keep the baby and move on to a promising and happy life. This spatial juncture, the train station, symbolizing a public space of modernity, and the contrasting hills like white elephants, symbolizing the personal dilemma of the pregnant girl, intersect in the characters’ lives and illustrate Bakhtin’s concept of chronotope. This particular chronotope reveals the conflict and tension between the hills like white elephants and the train station near the barren, dry, brown earth, as well as between the woman and man in their perceptions of their lives and future together. © 2024 Ovidius University.

Barriers To Bim Implementation in Sustainable Building Projects in Türkiye
(East Carolina University, 2024) Aksoy, I.; Akcay, E.C.
As the construction industry is a major contributor to greenhouse gas emissions, sustainable building projects play a vital role in mitigating its harmful environmental impact. Building energy analysis is particularly important for sustainable projects. Building Information Modeling (BIM), which enables comprehensive data management and analysis throughout the building lifecycle, has emerged as an indispensable tool at every stage of sustainable building projects. This study aims to investigate the barriers hindering the implementation of BIM in sustainable building projects in Türkiye. For this purpose, potential barriers were initially identified through literature searches in databases such as Scopus and Web of Science. Following the literature review, a structured questionnaire was designed to evaluate the significance of 18 identified barriers on the use of BIM technology in green buildings. The results indicate that significant impediments include financial barriers such as high licensing costs, the high costs of BIM experts, and high training costs. The findings highlight the critical need for support mechanisms to facilitate the broader adoption of BIM in sustainable construction practices. © 2024 International Conference on Construction in the 21st Century.

Besir Fuad's voltaire: Liberating the Individual
(Routledge Journals, Taylor & Francis Ltd, 2022) Muhurcuoglu, Korhan
Besir Fuad (1852?-1887) is an obscure figure among late nineteenth century Ottoman intellectuals known for his materialistic views which were unprecedented under the Hamidian regime (1876-1909) and who shocked his contemporaries by committing suicide at an early age, leaving a note and a letter containing his last impressions and world view. Just months before his suicide, Besir Fuad published a Voltaire biography in which he commemorates him as an Enlightenment ideal to be emulated in humankind's struggle against religious intolerance. In this article, Besir Fuad's Voltaire (1886) is examined, arguing that the monograph was, though in an embryonic form, an early expression and defence of individual liberty, based on a materialistic world view that aims at demystification of the prevailing customs and morals as irrational and superstitious absurdities to pave the way for a future society in which the individual would be in liberty.

Biological System Analysis in Bioinspired Conceptual Design (bicd) for Bioinspired Robots
(Romanian Soc Control Tech informatics, 2011) Eroglu, Aylin Konez; Eroğlu, Aylin Konez; Erden, Zuhal; Erden, Zühal; Erden, Abdulkadir; Erden, Abdulkadir; Eroğlu, Aylin Konez; Erden, Zühal; Erden, Abdulkadir; Department of Mechatronics Engineering; Department of Mechatronics Engineering; Mechatronics Engineering; Mechatronics Engineering; Department of Mechatronics Engineering; Mechatronics Engineering
Bioinspired design (BID) provides a systematic way for bioinspired applications. Although several BID approaches as well as some tools and databases are available in the literature, the studies on BID are still challenging for designers and/or engineers because of limitations of current BID approaches. There are mainly two directions related with these limitations. One of them is the representation of knowledge on biological systems and the second is the problem of transforming this knowledge into engineering domain. These limitations expose two questions; firstly, "What knowledge is required to describe biological systems?" and "How this knowledge is represented?" and secondly, "How this knowledge is transformed into the engineering domain?". This paper presents a study which aims to answer the first question about knowledge required to represent biological systems. This knowledge is obtained during "Analysis of Biological Systems" stage of a new suggested bioinspired conceptual design (BICD) procedure.

Bitcoin Market Price Analysis and an Empirical Comparison With Main Currencies, Commodities, Securities and Altcoins
(Springer Science and Business Media Deutschland GmbH, 2019) Pirgaip,B.; Dinçergök,B.; Haşlak,Ş.
The purpose of this study is to analyze Bitcoin (BTC) market prices and to answer the question of whether there is a relationship between BTC and other asset prices, where other assets include currencies, commodities, securities and altcoins. In the empirical part, we evaluate the lead-lag relationships among each type of asset. Consequently, we compare BTC with major currencies and stock exchanges of the U.S., the EU, the U.K. and Japan (USD-SPX, EUR-DAX, GBP-FTSE and JPY-NIK), with currencies and stock exchanges of the U.S., the U.K., Russia, Venezuela and China where BTC is actively traded (USD-SPX, GBP-FTSE, RUB-MOEX, VEF-IBVC and YUAN-SSCE), with major commodities (GOLD and OIL) and with major altcoins (ETH, XRP and LTC) on a daily basis for the period spanning from 2010.07 to 2018.12. We employ Johansen co-integration, Granger causality, impulse response functions and forecast error variance decomposition analyses in our study. Our results show that BTC does not have a long-run relationship with any asset type, but that it has a short-run relationship with gold and especially altcoins, which are both significant and bidirectional. While BTC and altcoins are closely interrelated with each other, BTC price variation is mostly borne by its own prices in all cases. © Springer Nature Switzerland AG 2019.
