Characterization of Miocene-Quaternary Mass Transport Complexes Using 3D Seismic Data, Southwestern Black Sea Kayhan, Deniz Yağmur; Altıner, Sevinç; Sipahioğlu, Özgür; Department of Geological Engineering (2025-9-25) Characterized by dim, chaotic and low-amplitude to transparent reflections in seismic data, mass transport complexes (MTCs) are gravity-driven deposits formed by downslope movements of sediments. In this study, a three-dim...
Nonlinear analysis of a laminated glass plate with mixed boundary conditions using the finite difference method Elçi, Deniz Can; Aşık, Mehmet Zülfü; Dural, Ebru; Department of Engineering Sciences (2025-9-11) The Finite Difference Method (FDM) is widely used to solve partial differential equations in various physical problems, including solid mechanics. In the analysis of laminated composite structures, FDM enables meshless s...
Situating regional policies: how important are they in populist surge and political divides in Europe? DEMİRDAĞ, İsmail; Ozatagan, Guldem; Eraydın, Ayda (2025-09-09) In this paper, we argue that understanding the role of regional policies and their outcomes on the recent populist disaffection of European voters with mainstream politics and their role in the political divides of Europe ...
Attitude Estimation with an Invariant Extended Kalman Filter Using Learning-Based Covariance Adaptation Arslan, Mehmet Emir; Saranlı, Afşar; Department of Electrical and Electronics Engineering (2025-9-1) This thesis proposes a data-driven method to improve attitude estimation performance by adaptively scaling the measurement noise covariance matrix within an Invariant Extended Kalman Filter (IEKF) framework. To achieve thi...
DESIGNING AND EVALUATING A CONCEPTUAL FRAMEWORK FOR GENERATIVE ARTIFICIAL INTELLIGENCE-ASSISTED FEEDBACK: AN EXPERIMENTAL STUDY IN AN UNDERGRADUATE PROGRAMMING COURSE Coşkun, Atakan; Er, Erkan; Department of Computer Education and Instructional Technology (2025-9-01) Despite the growing integration of artificial intelligence (AI) in education, research on pedagogically grounded AI chatbots remains limited, constraining their instructional potential. To address this gap, a human–AI coll...
Designerly Ways of Dealing with Organizational Problems Kesdi, Nimet Başar; Börekçi, Naz Ayşe Güzide Z.; Department of Industrial Design (2025-9-1) When first introduced to the industry, design was typically interested in producing products, industrial goods, graphic items, and interior designs; however, design has recently become a widely accepted innovation tool in ...
