Editorial Introduction(Springer, 2008) Aydogan, N.Article The Impact of Technology on Economic Growth in Turkey(Inderscience Publishers, 2025) Ercan, M.; Temiz, D.; Gökmen, A.The Turkish economy has been suffering from trade imbalance for a long time. Exporting high value-added products will diminish Turkey’s dependence on foreign resources for capital and imported products. At the same time, it may be possible to divert more resources from gross domestic product (GDP) to R&D funds. Appropriate and efficient usage of technology will help companies innovate and find new areas of employment. As a result, the Turkish economy may have a better chance of obtaining a sustainable economic growth for the longer term. This study concludes that increased R&D expenditures leads to a rise in technology and this in turn contributes positively to economic growth. The results obtained from the study show that technology affects Turkey’s economic growth. Therefore, Turkey needs to work harder in the field of technology in order to achieve sustainable growth. Improving the situation and quality of research and development activities in Turkey, encouraging research and development investments by both the government and the business sector should be priority reform movements for Turkey. Policy makers should support science and technology, make institutional arrangements for intellectual property rights and raise the level of education, and make arrangements to increase R&D spending. © 2025 Elsevier B.V., All rights reserved.Conference Object Citation - Scopus: 12Computation of Supervisors for Fault-Recovery and Repair for Discrete Event Systems(IFAC Secretariat, 2014) Sülek, A.N.; Schmidt, K.W.In this paper, we study the fault-recovery and repair of discrete event systems (DES). To this end, we first develop a new method for the fault-recovery of DES. In particular, we compute a fault-recovery supervisor that follows the specified nominal system behavior until a fault-occurrence, that continues its operation according to a degraded specification after a fault and that finally converges to a desired behavior after fault. We next show that our method is also applicable to system repair and we propose an iterative procedure that determines a supervisor for an arbitrary number of fault occurrences and system repairs. We demonstrate our method with a manufacturing system example. © 2021 Elsevier B.V., All rights reserved.Article Perturbed Statistical Convergence(Erdal Karapınar, 2025) Yalçin, CeylanThis paper examines the basic features of perturbed statistical convergence in the context of perturbed metric spaces. The suggested method expands on the standard concept of statistical convergence by using a perturbation function that shows the errors that might happen while measuring distance. The relations of this new type of convergence with classical and statistical convergence are discussed in detail. There are some examples and counterexamples that support the new theoretical results. © 2025 Elsevier B.V., All rights reserved.Article Citation - Scopus: 1Study of Impulsive Problem with Caputo Fractional Derivative Involving Nonlocal Conditions Using Fixed Point Theory(Kyungnam University Press, 2025) Dhandapani, Swathi; Umapathi, Karthik Raja; Mathuraiveeran, Jeyaraman; Shah, Kamal; Abdeljawad (Maraaba) T., Thabet; Jarad, Fahd; Abdeljawad, ThabetIn this article, we study the existence of solutions for an impulsive Caupto fractional differential equations with a class of initial value problem dependence on the Lipschitz first derivative conditions. Our main tool is a Banach's fixed point theorem and Leray-Schauder fixed point theorem. We also investigate the existence of fractional Derivative with non-local conditions. An numerical example is given to clarify the results. © 2025 Elsevier B.V., All rights reserved.Article Leisure Spaces of Pre-Republican Ankara During the Late Ottoman Period(Horizon Research Publishing, 2025) Önder, Demet; Başok, Gülşah Çelik; Mertyürek, SerkanThis research explores urban space and the leisure geography in pre-republican Ankara, the capital city of Turkey, during the late period of the former Ottoman Empire. While the epoch between 1919 and 1923 corresponds to the last years of the fallen Ottoman Empire, it also overlaps with the time interval the city witnessed the National Independence War as a central stronghold and a democratic political center. Soon after the victory of the Independence War, the new Turkish Republic was founded as a modern state, and Ankara was declared the capital city. In particular, this research explores 'socio-spatial dialectics' about leisure activities and urban space. It posits that leisure activities shape urban spaces and are influenced by their contextual environment, including economic, cultural, historical, and social factors. The study examines the historical significance of recreational spaces, which were often absent or underdeveloped in Ankara due to economic decline and urban destruction, particularly after the 1917 fire. It highlights the lack of designated recreational spaces in pre-republican Ankara, where social gatherings occurred primarily in open public spaces and informal settings. The emergence of specific leisure venues, such as coffee shops, theatres, and parks, is traced through historical narratives, showing how leisure preferences evolved alongside the city's geography and socio-economic changes. The paper concludes that the development of recreational spaces in Ankara was gradual and reflected broader socio-cultural dynamics, particularly as the city transitioned into a modern urban center by the start of the 1920s. This research aimed to inform and help understand the limited landscape devoted to leisure in Ankara in the pre-republican era, which was core to understanding the leisure geography in the capital city of the young Turkish Republic. The analysis provides insights into the reciprocal relationship between leisure activities and urban space and highlights the importance of historical context in shaping recreational landscapes. © 2025 Elsevier B.V., All rights reserved.Article Citation - Scopus: 7COVID-19 Classification Using Hybrid Deep Learning and Standard Feature Extraction Techniques(Institute of Advanced Engineering and Science, 2023) El Shenbary, H. A.; Ebeid, Ebeid Ali; Baleanu, Dumitru I.There is no doubt that COVID-19 disease rapidly spread all over the world, and effected the daily lives of all of the people. Nowadays, the reverse transcription polymerase chain reaction is the most way used to detect COVID-19 infection. Due to time consumed in this method and material limitation in the hospitals, there is a need for developing a robust decision support system depending on artificial intelligence (AI) techniques to recognize the infection at an early stage from a medical images. The main contribution in this research is to develop a robust hybrid feature extraction method for recognizing the COVID-19 infection. Firstly, we train the Alexnet on the images database and extract the first feature matrix. Then we used discrete wavelet transform (DWT) and principal component analysis (PCA) to extract the second feature matrix from the same images. After that, the desired feature matrices were merged. Finally, support vector machine (SVM) was used to classify the images. Training, validating, and testing of the proposed method were performed. Experimental results gave (97.6%, 98.5%) average accuracy rate on both chest X-ray and computed tomography (CT) images databases. The proposed hybrid method outperform a lot of standard methods and deep learning neural networks like Alexnet, Googlenet and other related methods. © 2022 Elsevier B.V., All rights reserved.Article Dispossessed Homes: Remembering Cyprus in the Aftermath of Conflict(Routledge Journals, Taylor & Francis Ltd, 2025) Pancaroglu, Seda BaharThis paper will interrogate the reconfiguration of "home" in the context of the Cyprus conflict, as depicted in Christy Lefteri's novel A Watermelon, a Fish, and a Bible. The long history of ethnic and political tensions between the Greek Cypriot and Turkish Cypriot communities escalated with political instability and reached its peak in 1974. Set during the heated midst of the 1974 conflict, Lefteri's novel offers multiple meanings of home through shifting focalisation. This study combines focalisation from narratology with Henri Lefebvre's the Production of Space, enriched by theories surrounding the notion of home. This analytical framework enables a comprehensive exploration of how narrative perspectives both shape and reflect the phenomenology of space in literature, particularly within conflict zones. This approach is particularly relevant for analysing divided or contested geographies, such as Cyprus in Christy Lefteri's A Watermelon, a Fish, and a Bible. By examining how characters perceive and navigate their surroundings, the analysis will reveal how "home", once seen as secure, familiar, or sacred, is redefined by conflict and how new meanings emerge in moments of crisis. It also highlights the dialogic nature of spatial experience in literature, where multiple perspectives on space can coexist, clash, and influence each other, reflecting the complexity of lived experience in a divided realm.Article Phenomenological Study of Lithium-Sodium Tetragermanate Close to the Phase Transition(Springer Nature, 2025) Kiraci, AliThis study presents an analysis of the dielectric and thermal properties in the vicinity of the second-order ferroelectric phase transition, with a specific emphasis on lithium-sodium tetragermanate, LiNaGe<inf>4</inf>O<inf>9</inf>. The power-law equation is employed by modifying the Kouvel-Fisher (KF) technique, which articulates the magnetization () and magnetic susceptibility in relation to the spontaneous polarization () and the dielectric constant () within ferroelectric frameworks. A parallel methodology is adopted to elucidate the heat capacity () and thermal expansivity () in the vicinity of phase transitions occurring in LiNaGe<inf>4</inf>O<inf>9</inf>. We demonstrate that the continuous fluctuations in and with temperature nearing the Curie point (T<inf>C</inf>108 K) as an indication of a second-order transition in LiNaGe<inf>4</inf>O<inf>9</inf>. Furthermore, a linear correlation is also established between and with temperature approaching the Curie point T<inf>C</inf> for this crystal structure. Experimental data are used from the literature for our analysis. Our findings show that the critical behavior of one dielectric or thermal property near the transition temperature in LiNaGe<inf>4</inf>O<inf>9</inf> can be predicted from the other through these linear relationships. The methodology articulated herein for delineating the dielectric and thermal characteristics of LiNaGe<inf>4</inf>O<inf>9</inf> close to the Curie point is extendable to various other ferroelectric materials. © 2025 Elsevier B.V., All rights reserved.Article Integrating the Seljuk Cultural Layer Into Contemporary Life: The Case of Niğde Historic City Center(Istanbul Univ, Research Inst Turkology, Dept Art History, 2025) Yavaşcan, Emel Efe; Urak, Zehra GedizGünümüz tarihî kent merkezleri, yer altı ve yer üstündeki tarihî izleriyle, kültürel zenginlikleri ve özgün kimlikle8 rinin yanı sıra, “yerin ruhu”nu yansıtan kentsel hafıza alanlarıdır. Çok katmanlı bu tarihî kent merkezleri, kültür varlıklarının fiziksel ve işlevsel eskimesi, sosyo8kültürel ve ekonomik doku bozulmaları, koruma problemleri vb. sorunlarla giderek çöküntü yerleri hâline gelmektedir. Bu sorunları barındıran Niğde kentinde yapılmış koruma uygulamalarında, kentin yer altında ve yer üstünde bulunan katmanlarının dikkate alınmamış olması çalışmada problem olarak belirlenmiştir. Kentli tarafından tepe olarak algılanan çalışma alanı uzun zamandır çöküntü alanı niteliğindedir. Çalışmanın amacı, Niğde Tarihî Kent Merkezi’nin Selçuklu Dönemi’ne ait tarihî katmanını analiz etmek, haritalan8 dırmak ve bu katmanı çağdaş koruma uygulamalarına entegre etmeye yönelik öneriler geliştirmektir. Araştırma verileri, kentin tarihî gelişiminde en belirleyici dönemin Selçuklu Dönemi olduğunu göstermektedir. Bu sebeple çalışma kapsamında bu katman odak alınmıştır. Ayrıca, diğer tarihî katmanların da korunarak günlük yaşama kazandırılmasına katkı sağlamak, bu çalışmanın bir diğer hedefidir. Bu bağlamda, Selçuklu Dönemi’ne ait yer üstü ve yer altı değerlerinin sürdürülebilir korunmasına yönelik öneriler geliştirilmiştir.
