Book Part Modeling Gradual and Joint Coverage in Location Problems(World Scientific Publishing Co., 2025) Eriskin, Levent; Karatas, Mumtaz; Yakici, ErtanBook Part Gazing Back in Anger: Forms of Aggression in A. S. Byatt’s Matisse Stories(Bloomsbury Publishing Plc., 2026) Uzundemir, ÖzlemBook Part Comparison of Damage Predictions for Concrete Dams, Finite Elements with Smeared Crack vs. Discrete Element Models(International Association for Earthquake Engineering, 2024) Soysal, B.F.; Arici, Y.The seismic assessment of gravity dam monoliths has been treated within the framework of performance based earthquake engineering (PBEE) in the last decade. The necessary inclusion of the soil-structure-reservoir interaction in combination with predicting the damage on these structures for use in PBEE is a significant challenge. Within this context, smeared crack models with general purpose finite element codes became to be used generally as the assessment tool for these systems. Perhaps the most practical limitation in this approach is the difficulty with providing discrete cracks and the corresponding impediment to the rating of the damage on these systems leading to possibly subjective conclusions. On the other hand, discrete element techniques offer a proficient simulation alternative to the FE, enabling the interpretation of results from the main aspect of the damage on these system, i.e. cracking. A novel discrete element framework, incorporating dam-reservoir interaction, has been developed to this end as part of the doctoral studies of the first author. The model incorporates individual elements connected by multiple springs, successfully modelling initial continuum with the accurate prediction of discrete cracks at the latter stages of loading. The predicted damage and damage rating of a generic monolith is compared to the FE counterparts in this work. A comprehensive comparison with different ground motions at several levels focusing on crack widths is shown. The results showed the cracking on the system is very different in severe shaking compared to similar predictions in lower earthquake excitations. The FE simulations, commonly adopted for the investigation of these systems with smeared crack modelling, yielded less cracking as well as smaller propagation in severe shaking conditions. © 2024, International Association for Earthquake Engineering.

Pivotal to the protagonist’s journey is his discovery of a painting. Depicting a scene from Mozart’s opera, Don Giovanni, the painting marks the protagonist’s departure to finding meaning in a complex world. His self-discovery hinges on the arts, leading the protagonist to grasp his essence and place in an indifferent and absurd universe. Fantastic and surreal events in the novel can be seen as an adaptation of Kierkegaard’s existentialism, a reinterpretation of the philosopher’s tenets to fit the twenty-first century. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.Book Part Citation - Scopus: 4Parallel Data Reduction Techniques for Big Datasets(IGI Global, 2016) Yıldırım, A.A.; Özdoǧan, C.; Watson, D.Data reduction is perhaps the most critical component in retrieving information from big data (i.e., petascale-sized data) in many data-mining processes. The central issue of these data reduction techniques is to save time and bandwidth in enabling the user to deal with larger datasets even in minimal resource environments, such as in desktop or small cluster systems. In this chapter, the authors examine the motivations behind why these reduction techniques are important in the analysis of big datasets. Then they present several basic reduction techniques in detail, stressing the advantages and disadvantages of each. The authors also consider signal processing techniques for mining big data by the use of discrete wavelet transformation and server-side data reduction techniques. Lastly, they include a general discussion on parallel algorithms for data reduction, with special emphasis given to parallel waveletbased multi-resolution data reduction techniques on distributed memory systems using MPI and shared memory architectures on GPUs along with a demonstration of the improvement of performance and scalability for one case study. © 2025 Elsevier B.V., All rights reserved.Book Part Citation - Scopus: 1Enterprise Architecture for Personalization of E-Government Services: Reflections From Turkey(IGI Global, 2012) Erdem, A.; Medeni, İ.T.; Medeni, T.D.As there has not yet been enough work on enterprise architectures for fully integrated knowledge-based, highly-sophisticated (citizen-oriented) personalized services, this chapter aims to articulate a perspective to design architectures for the development and provision of sophisticated, personalized services. Doing so, the authors benefit from their knowledge and experience in the Turkish e-Government Gateway (eGG) and general e-Government services development and provision. First providing an introduction and background information, the chapter discusses the development of eGG services in Turkey, and then provides a visionary suggestion for knowledge-based personalized, citizen-centric e-Government. Among the suggested perspectives, an E-Citizen Decision Support System, and Entity-Utility and Information Flow Model could be useful for eGG development in Turkey and elsewhere. © 2025 Elsevier B.V., All rights reserved.Book Part Intra-State Conflict in the Post-Cold War Balkans: The Macedonian Case and Consociationalism(Bloomsbury Publishing Plc., 2020) Ekinci, DidemBook Part Middle East Policy, Regional Powers(Bloomsbury Publishing Plc., 2019) Karadeli, Sedat Cem; Leitich, Keith A.; Pierpaoli, Paul G.; Tucker, Spencer C.Book Part Citation - Scopus: 1The NGO Forum(IGI Global, 2008) Nahar, Nurun; Medeni, Tunç Durmuş; Medeni, TolgaThis article examines the unique characteristics of the NGO forum as a networked organization, that is, an organization structure that relies on multiparty cooperative relationships between people across structural, temporal and geographic boundaries. It studies the working methodology of the forum to discover the knowledge creation process and how such an organization utilizes its experience and knowledge work to be a successful development partner with all concerned stakeholders. Moreover, communication among forum stakeholders is not the result of random, but deliberate interactions done in the manner of a community of practice (CoP), which in turn is a part of the epistemic community that is influencing the national, global policies on water and sanitation. The study also brings out that an “environmental information system” is very important for it to function as a networked organization. © 2025 Elsevier B.V., All rights reserved.Book Part Citation - Scopus: 4Inflation and Growth: an Empirical Study for the Comparison of the Level and the Variability Effects(Nova Science Publishers, Inc., 2006) Arin, K.P.; Omay, Tolga; Omay, T.; Çankaya Meslek YüksekokuluThis paper analyzes the interaction between the inflation and growth within the Mankiw-Romer-Weil (1992) framework. Our results indicate that the inflation level has a significant negative effect on output in advanced capitalist economies, whereas inflation variability has a negative and significant effect on output in the long-run for all sub-samples. Our results also show that the variability effects are larger in terms of significance. © 2006 Nova Science Publishers, Inc. All rights reserved.
