Shape complexity: relative and emergent, with applications in deep learning Arslan, Mazlum Ferhat; Tarı, Zehra Sibel; Department of Computer Engineering (2024-3-15) Quantifying shape complexity is useful for a variety of applications including medical imaging and measuring the difficulty of samples in image datasets. However, the subject is underexplored, mostly due to its multifaceted nature. In this thesis, we start by proposing a benchmark dataset, subsets of which aim to account for the different aspects of the phenomenon. We compare a variety of shape complexity-related measures on the proposed dataset. Next, we propose a novel method that emphasizes the relative...
INVESTIGATION OF THE INTERACTION OF ORGANICS WITH PRISTINE AND AGED POLYETHYLENE: THE CASE FOR PHENOL, TRICHLOROPHENOL, AND TETRACHLOROETHANE Çiftçi, Gökçe; İmamoğlu, İpek; Department of Environmental Engineering (2024-3-15) Microplastics, plastic particles under 5 mm in diameter, are widespread and may act as carriers for contaminants in the environment. This study aims to enhance our understanding of the sorption behavior of selected organics—phenol, 2,3,6- trichlorophenol (TCP), and 1,1,2,2-tetrachloroethane (PCA)—on pristine and UV-aged polyethylene (PE) microplastics. The main part of the experiments was conducted with the latter two compounds due to lack of affinity of phenol for PE. Results underscore the complex interpl...
A Kristevan Reading of Mine Söğüt's Novels Çiftci, Zehra; İbrahimhakkıoğlu, Fulden; Department of Gender and Women's Studies (2024-4) This thesis delves into Mine Söğüt’s novels through the theoretical lens provided by Julia Kristeva, mainly focusing on Kristeva’s concepts of the semiotic and the abject. Söğüt’s narratives are characterized by their exploration of unsettling themes, the portrayal of marginalized women and queer characters, and the incorporation of unconventional narrative elements. As such, this study undertakes both thematic and structural explorations of Söğüt’s works, linking the unsettling themes to Kristeva’s concept...
Investigations of 2D Materials Towards THz Source and Detector Applications Aytekin, Yusuf Samet; Esentürk, Okan; Department of Chemistry (2024-3-08) The work investigates static and dynamic properties of 2D materials, graphene to transition metal dichalcogenides, for their possible use as a Terahertz source or detector. The static properties in THz domain were carried out with Time-Domain THz Spectroscopy (THz-TDS), while dynamic properties were investigated via Time-Resolved Terahertz Spectroscopy (TRTS) systems. The initial part of the studies was optimization of the terahertz systems thus after the optimizations the bandwıdth was expanded and S/N hav...
INVESTIGATION AND IMPROVEMENT OF COMBINED CYCLE POWER PLANTS BY MODIFYING HEAT RECOVERY STEAM GENERATION SECTION Hassan, Munzir; ORANG, ALİ ATASHBAR; Mechanical Engineering (2024-1) As the world's energy demand increases and shifts to more fuel-efficient production systems, the combined cycle power plants (CCPP) remain at the peak of thermal efficiency at 63.7%. So, any improvement will have considerable environmental and economic benefits. This study focuses on a power plant using a natural gas heavy-duty gas turbine thermodynamic optimizations will be conducted using MATLAB to model an essential device in the CCPP called a Heat recovery steam generator (HRSG), which recovers the heat...
Investing in authoritarianism: Saudi Arabia and the UAE’s FDI inflows into Egypt under Sisi Küçük, Ömer Naim; Altunışık, Meliha; Department of International Relations (2024-5) The study investigates the role of Foreign Direct Investment (FDI) in bolstering authoritarian resilience in host countries, focusing on investment inflows of Saudi Arabia and the United Arab Emirates (UAE) into Egypt from the early 2000s to 2023. Utilizing a mixed-method research design that combines insights from quantitative and qualitative analyses, the research suggests that FDI inflows can reinforce authoritarian regimes by enhancing the financial resources available to authoritarian incumbents and so...
EFFICIENCY ANALYSIS OF METAL MARKETS Kara, Alper; Tunç, Gül İpek; Yıldırım Kasap, Dilem; Department of Economics (2024-5) This study analyzes the weak-form efficiency of global metal markets. We focus on both spot metal markets and three-month futures metal markets. To investigate the efficiency of spot metal markets, we examine the producer price index adjusted nominal prices of six base metals (copper, lead, aluminum, nickel, zinc, and tin) and three precious metals (gold, silver, and platinum). In the second chapter, we present a descriptive analysis, price dynamics, and an efficiency discussion about these metals. We apply...
The Politics of Humanitarian Assistance in Syria's Civil War Seven , Ümit; Altunışık, Meliha; Department of Area Studies (2024-1) This research explores the dynamics of interaction between the Syrian government and international aid actors in Syria’s civil war. Its primary objective is to understand the palpable manifestations of state sovereignty in humanitarian action and their impact on humanitarian norms and principles. Employing a mixed methods approach, this research unveils spatial configuration of international humanitarian assistance that emerge from daily practices, negotiations, and violence within the civil war. I contend ...
Building A Digital Narrative For Komana: A Theoretical And Methodological Approach Of Deep Mapping Sevimli, Ezgi; Erciyas, Deniz Burcu; Department of Settlement Archaeology (2024-4-26) Fast-paced development of digital technologies and their adoption in archaeological research provides possibilities for experimenting with new methods of archaeological interpretation and integration of theoretical perspectives. Especially, previously implausible applications of highly sophisticated theoretical aspects of landscape studies can be implemented practically through digital techniques and methods. The objective of this thesis is to develop a digital deep mapping methodology which incorporates bo...
Architectural Awards, Content Analysis, Underlying Narratives Shahri, Mohammadjavad; BALAMİR, AYDAN; Department of Architecture (2024-3-11) After 45 years, 15 cycles and numerous seminars and publications, the Aga Khan Award for Architecture (AKAA) has accumulated a collection of noteworthy works. This study seeks to explore the history and progression of the award program by scrutinizing its selection criteria, underlying narratives, and its contributions to the field of architectural discourse. The research investigates how the award correlates with architectural approaches of its time, and the diverse issues tackled by it. In scrutinizing th...

GRAPH-BASED HIERARCHICAL TRACKLET MERGE FOR MULTIPLE OBJECT TRACKING Bilgi, Halil Çağrı; Alatan, Abdullah Aydın; Department of Electrical and Electronics Engineering (2024-4-05) The past decade has seen significant advancements in multi-object tracking, particularly with the rise of deep learning. However, many studies in online tracking have primarily focused on enhancing track management or extracting visual features, often leading to hybrid approaches with limited effectiveness, especially in scenarios with severe occlusions or crowded scenes. Conversely, in offline tracking, there has been a lack of emphasis on robust motion cues. This thesis proposes a novel solution to offlin...
