Doctoral Thesis A Study on Number Theoretic Construction and Prediction of Two Dimensional Acoustic Diffusers for Architectural Applications(Izmir Institute of Technology, 2011) Döşemeciler, Ayşe; Doğan, FehmiDefined as the scattering of sound independent from angle, optimum diffusion is very important for the perception of musical sound. For this purpose, Schroeder used mathematical number sequences to propose ʼreflection phase grating diffusersʼ, of two main types: Single plane or one-dimensional (1D) diffusers that scatter sound into a hemi-disc, and two dimensional (2D) diffusers that scatter into a hemisphere to disperse strong specular reflections without removing sound energy from the space, which is the main advantage of these devices. Currently, two methods are used to design 2D diffusers:Product Array and Folding Array Methods. Both are based on number theory and used methodologically in the field of acoustics, producing results that offer limited diffusion characteristics and design solutions for a variety of architectural spaces ranging from concert halls to recording studios where Schroeder diffusers are widely used. This dissertation proposes Distinct Sums Property Method originally devised for watermarking digital images, to construct adoptable 2D diffusers through number theoretical construction and prediction. At first, quadratic residue sequence based on prime number 7 is selected according to its autocorrelation properties as the Fourier transform of good autocorrelation properties gives an even scattered energy distribution. Then Distinct Sums Property Method is applied to construct 2D arrays from this sequence from which well depths and widths are calculated. Third, the aimed scattering and diffusion properties of the modeled 2D diffuser are predicted by Boundary Element Method which gives approximate results in accordance with the measurements based on Audio Engineering Society Standards. Fourth, polar responses (i.e. the scattering diagrams for specific angles) in each octave band frequency are obtained. Finally, predicted diffusion coefficients for uniform scattering are calculated and compared to the reference flat surfaceʼs coefficients and previous studieʼs results.Article Citation - WoS: 6Citation - Scopus: 7Contextualising the Housing Problem of the Roma Community in Relation To Counterurbanisation in Urla, İzmir(Elsevier, 2024) Arslan Avar, Adile; Doğan, Fehmi; Özcan Cive, Yağmur; Akış, TonguçThis paper examines how the housing problem of the Roma people, living already under severe socio-spatial circumstances, has been exacerbated by counterurbanisation over recent decades in the resort town of Urla, İzmir. Based on empirical socio-spatial research adopting methodological pluralism integrating qualitative and quantitative research techniques, the study uses in-depth interviews and secondary data (e.g., real-estate web data, official statistics, and local media) as well as spatial analysis of satellite images. We limited our study to the proximity of the town center of Urla, considering the Roma community's ‘right to the city’, ensuring their right not to be exiled to the spaces of discrimination, and not to be exempted from their right to appear and co-exist in the town center. As Urla became a prominent and attractive destination of counterurbanisation in Turkey, its growth was intensified by high-end housing production. Coming to 2000s, its urban-rural texture remained, at least physically, ‘rural’, but it had undergone significant transformation. And while this recent higher-end development accompanied by counterurbanisation is sanctioned by local authorities, the public and property owners, it leaves no room for the Roma people to find decent housing. An inquiry on the housing problem of the Roma people in Urla in relation to counterurbanisation and accompanying housing production contributes to understanding the dialectics between deregulated housing market, commodification and uneven distribution of treasury lands, neoliberal regulations, and fragmented development plans implemented in highly “path-dependent” ways. © 2023 Elsevier LtdArticle On the Strengths and Weaknesses of Virtual Reality in Distance Estimation in AEC Domain: A Meta-Analysis of Literature 2014–2024(Springer Science and Business Media Deutschland GmbH, 2026) Kurpınar, G.; Doǧan, F.; Çevik, A.; Kasali, A.Virtual reality (VR) became the most used extended reality system in architecture, engineering, and construction domains. It offers advantages through its immersive and interactive interface. There is, however, a need to investigate both its strengths and weaknesses especially in relation to the claim that it is a close surrogate for real-world performances. This study reports the findings of a meta-analysis on distance estimation (DE) in VR. Distance estimation, essential for spatial perception, remains to be a problem in VR even with advanced head-mounted displays. The study questions whether VR can match the real-world performance in DE to highlight its shortcomings as well as its potentials. The meta-analysis includes 77 pieces of data from 29 studies and investigates whether DE accuracy has improved and how DE interacts with task type, task environment, and target range. The results indicate VR is still underperforming in DE, head-mounted display’s weight is the significant factor, and task type and task environment significantly interact with DE. We conclude VR needs to be specifically tailored regarding the needs of practitioners in architecture and engineering industry and that it is not yet a substitute for real-world performances. © The Author(s) 2025.Article Citation - WoS: 3Citation - Scopus: 6Use of Analogies, Metaphors, and Similes by Students and Reviewers at an Undergraduate Architectural Design Review(Cambridge University Press, 2019) Doğan, Fehmi; Taneri, Batuhan; Erbil, LivanurThis study investigates the use of similarities in the form of analogy, metaphor, and simile by students and reviewers in an undergraduate architectural design review. In contrast to studies conducted in vitro settings, this study emphasizes the importance of studying analogies, metaphors, and similes in a natural setting. All similarity relationships were coded according to their type, the level of expertise, range, frequency, goal, value judgment, and depth. The results indicate that analogies, metaphors, and similes were used spontaneously and without any difficulty by both reviewers and students. Reviewers, however, were almost twice as likely to evoke similarities. Metaphor was the most frequently used similarity relationship among the three. It was found that there was a significant relationship between the level of expertise and type of similarity, with students more likely to use analogies and less likely to use similes. It was also found that goal is the most important factor, with a significant relation to all other variables, and that embodiment is often invoked in both students' and reviewers' metaphors. We conclude that design education should take full advantage of students' natural ability to benefit from similarity relationships.Article Citation - WoS: 12Citation - Scopus: 12Fifth-, Sixth-, and Seventh- Grade Students' Use of Non-Classroom Spaces During Recess: the Case of Three Private Schools in Izmir, Turkey(Academic Press Inc., 2010) Kasalı, Altuğ; Doğan, FehmiThis study investigates fifth, sixth, and seventh grade students' place preferences between indoor and outdoor non-classroom spaces during recess and their activity patterns in these spaces in three private elementary schools. The study explores whether differences in the variety and organization of the spaces of school facilities have an impact on the place preferences of students and whether students are aware of the reasons for their preferences. Students' place preferences and their activities were determined with field observations and a 30-item questionnaire with Yes/No and open-ended questions. A total of 173 students (n = 51 School 1; n = 70 School 2; and n = 52 School 3) participated in the questionnaire. The Chi-Square test, a non-parametric statistical analysis test, was used to analyze the students' answers to the questionnaire. The results indicate that students prefer places which offer variety and which are large enough to avoid congestion and that, in general, students are aware of the spatial features of their environments and make choices accordingly. When students are given a choice of outdoors or indoors, they tend to choose according to which is more conducive to their activities. If both outdoor and indoor spaces are conducive, students tend to use both. If neither is conducive to their activities, students either alter their behavior patterns, for example, developing a preference for stationary activities or staying inside the classroom, or they convert available spaces to accommodate their activities. It is concluded that students are good sources of information in the design and planning of the environments they occupy. © 2010 Elsevier Ltd.Article Reflection on Designing: Metacognitive Interventions to Enhance Metacognitive Awareness, Motivation, and Performance in Design Learning(Springer, 2025) Yazici, Gizem; Dogan, FehmiDesign education involves ill-defined problem-solving that demands both creativity and self-regulation. While metacognitive awareness significantly enhances learning outcomes and motivation, there is limited empirical evidence on how to systematically foster this skill in design studios. This study aims to investigate whether metacognitive interventions increase architecture students' metacognitive awareness levels, academic goal orientations, and design course success. In a quasi-experimental design, 84 third-year architecture students were divided into experimental (n = 58) and control (n = 26) groups. Pre-post-test data were collected using the MAI and AGOQ scales. Three structured interventions were implemented in the experimental group over six weeks. In the students who received the interventions, significant increases were observed in metacognitive awareness, mastery-performance goal orientation, and design course grades. In students with high awareness, mastery orientation, metacognitive awareness, and design course grades increased significantly, while in students with low awareness, metacognitive awareness and performance orientation increased. Pretest MAI and AGOQ scores accounted for 72.8% of the variance in grades, with MAI showing the strongest positive influence. Learning and proving orientations were moderately and positively correlated to grades, while avoidance orientation showed a moderate negative correlation. Metacognitive interventions enhance learning outcomes in design education by supporting metacognition and motivation.Article Citation - WoS: 12Citation - Scopus: 17Pyramiding Multiple Genes for Resistance To Pvy, Tswv and Pmmov in Pepper Using Molecular Markers(Verlag Eugen Ulmer, 2014) Özkaynak, E.; Devran, Z.; Kahveci, E.; Doğanlar, Sami; Başköylü, B.; Doğan, F.; İşleyen, M.; Yüksel, A.; Yüksel, M.Pepper (Capsicum annuum L.) is one of the most important vegetables cultivated worldwide. Many pests and pathogens cause economic yield losses in pepper. Potato virus Y (PVY), Tomato spotted wilt virus (TSWV) and Pepper mild mottle virus (PMMoV) are considered among the most destructive viruses affecting pepper in the world. Because chemical treatments have limited success for managing PVY, TSWV and PMMoV, resistant varieties are considered to be the most effective means of controlling these viruses. In this study, resistance genes to these viruses were successfully transferred to the superior sweet Charleston pepper line 'Y-CAR' using molecular markers and biological assays. As a result, a new line which is resistant to PVY, TSWV and PMMoV was developed. The results also showed the applicability of a pyramiding strategy for breeding multiple virus resistance in pepper. © Verlag Eugen Ulmer KG, Stuttgart.Master Thesis An Evaluation of Non-Classroom Spaces of Private Elementary Schools in I·zmir: Investigating Facors Affecting Interactions Among Students(Izmir Institute of Technology, 2006) Kasalı, Altuğ; Doğan, FehmiThis study investigates the role of non-classroom spaces of elementary school buildings where informal interactions among students take place in the example of private elementary schools in zmir, Turkey. The non-classroom spaces that students prefer during their free times are important in the way they facilitate peer interactions which may contribute to informal learning processes. The elementary school students' space and activity preferences were investigated in their free times by focusing on nonclassroom spaces of school buildings. Multiple case study method is used. The cases were selected among private elementary schools in zmir based on their educational programs and based on their characteristics of indoor and outdoor non-classroom spaces. Post-occupancy evaluation (POE) techniques were used to collect data. The research indicated that regardless of differences among schools, students want to interact with their friends during breaks. Students prefer to spend their free time at places that facilitate these interactions. This study provides a brief list of activities and places that students prefer during their free time. There is evidence suggesting that places where students prefer to spend time differ from one school to another in terms of indoors and outdoors. The research indicates that students involve in similar activities with different frequencies in schools studied and in case when students are given a choice between indoor and outdoor spaces with different degree of variety they are conscious of the difference and they tend to pick spaces which offer higher variety.Conference Object Citation - Scopus: 1Classification of Turkish and Balkan House Architectures Using Transfer Learning and Deep Learning(Springer Science and Business Media Deutschland GmbH, 2024) Yönder,V.M.; İpek,E.; Çetin,T.; Çavka,H.B.; Apaydın,M.S.; Doğan,F.Classifying architectural structures is an important and challenging task that requires expertise. Convolutional Neural Networks (CNN), which are a type of deep learning (DL) approach, have shown successful results in computer vision applications when combined with transfer learning. In this study, we utilized CNN based models to classify regional houses from Anatolia and Balkans based on their architectural styles with various pretrained models using transfer learning. We prepared a dataset using various sources and employed data augmentation and mixup techniques to solve the limited data availability problem for certain regional houses to improve the classification performance. Our study resulted in a classifier that successfully distinguishes 15 architectural classes from Anatolia and Balkans. We explain our predictions using grad-cam methodology. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.Conference Object Decoding and Predicting the Attributes of Urban Public Spaces With Soft Computing Models and Space Syntax Approaches(Ecaade-education & Research Computer Aided Architectural design Europe, 2023) Yonder, Veli Mustafa; Dogan, Fehmi; Cavka, Hasan Burak; Tayfur, Gokmen; Dulgeroglu, OzumPeople spend a considerable amount of time in public spaces for a variety of reasons, albeit at various times of the day and during season. Therefore, it is of utmost importance for both urban designers and local authorities to try to gain an understanding of the architectural qualities of these spaces. Within the scope of this study, squares and green parks in Izmir, the third largest city in Turkey, were analyzed in terms of their dimensions, landscape characteristics, the quality of their semi-open spaces, their landmarks, accessibility, and overall aesthetic quality. Using linear predictor, general regression neural networks, multilayer feed-forward neural networks (2-3-4-5-6 nodes), and genetic algorithms, soft computing models were trained in accordance with the results of the conducted analyses. Meanwhile, using space syntax methodologies, a visibility graph analysis and axial map analysis were conducted. The training results (i.e., root mean square error, mean absolute error, bad prediction rates for testing and training phases, and standard deviation of absolute error) were obtained in a comparative table based on training times and root mean square error values. According to the benchmarking table, the network that most accurately predicts the aesthetic score is the 2-node MLFNN, whereas the 6-node MLFN network is the least successful network.
