    Structural Performance of Authentic Architectural Heritage Designs: a Masonry Monument in Western Anatolia
    (KeAi Communications Co., 2023) Demir, H.A.; Hamamcıoğlu-Turan, M.; Yücetürk, K.; Aktaş, E.
    The aim of the study is to present a multi-leveled comparative evaluation approach for structural characteristics of historic masonry monuments so that the consciousness in their authentic designs is comprehended, and the optimum structural performance is clarified. A case study approach is preferred by the examination of the Bedesten (15th‒16th centuries) located in Bergama, İzmir, Turkey. The structure is documented through tacheometric techniques. The construction techniques of structural elements are mapped. These documented qualities are compared with similar period and/or function structures in order to rank the frequency of construction details. The geometrical factor of safety state is defined theoretically for domes and arches. Finite element macro model of the Bedesten is generated in ANSYS software and overall structural analysis of the structure is made to evaluate the safety level of historic building by the limit states through self-weight analysis. The presented study shows that the rare structural characteristics can both contribute to structural safety and cause vulnerability. Therefore, total consciousness in structural design cannot be stated for the studied Bedesten, but the structural designs that are often preferred in the monuments built at the same period in the proximity to each other have low vulnerability, yielding to conscious preferences. © 2023 Higher Education Press Limited Company

    Factors Influencing Student Information Technology Adoption
    (Institute of Electrical and Electronics Engineers, 2023) VanDerSchaaf, Hans P.; Daim, Tuğrul U.; Başoğlu, Ahmet Nuri
    Innovating service delivery in higher education by leveraging technology is central to supporting goals of transforming higher education to center on the needs of today's students. Aligned with these goals, this article identifies key determinants of student information technology adoption. Using a mixed-methods and empirical approach based on the Unified Theory of Acceptance and Use of Technology (UTAUT), a web-based survey was administered to undergraduate students at a public university in the Western United States to learn about their experiences with a web-based digital services platform (native mobile app and website), that aids students in accessing services and resources critical to maintaining their enrollment. Structural Equation Modeling, including Principal Components Analysis, was used to analyze 1841 valid survey responses and derive statistical results. The findings suggest that effort expectancy and social influence stand out as critical influences on behavioral intention to adopt the software for accessing university services, and new to UTAUT, that social influence and a students’ basic technology skills are significant determinants of effort expectancy. This article makes unique contributions to the research literature. It applies UTAUT to a higher education context to help explain the critical determinants of the adoption of software for accessing university services. It also provides insights for how UTAUT can be applied in the university setting and offers suggestions for enhancing UTAUT. IEEE

    The Convergence of a New Symmetric Iterative Splitting Method for Non-Autonomous Systems
    (Taylor and Francis Ltd., 2012) Tanoğlu, Gamze; Korkut, Sıla
    The iterative splitting methods have been extensively applied to solve complicated systems of differential equations. In this process, we split the complex problem into several sub-problems, each of which can be solved sequentially. In this paper, we construct a new symmetric iterative splitting scheme based on the Magnus expansion for solving non-autonomous problems. We also study its convergence properties by using the concepts of stability, consistency, and order. Several numerical examples are illustrated to confirm the theoretical results by comparing frequently used methods. © 2012 Copyright Taylor and Francis Group, LLC.
