Regime-aware day-ahead electricity consumption forecasting for Türkiye: A meta-learning-based ensemble approach Savaş, Alp Demir; Koçyiğit, Altan; Department of Information Systems (2026-6) Day-ahead electricity consumption forecasting is very important for power system operation, market planning, and reserve scheduling. This thesis focuses on developing accurate day-ahead electricity consumption profiles for Türkiye. The main aim is to forecast the hourly consumption profile for the next day under real operating conditions. For this purpose, hourly national consumption data together with weather and calendar variables were used for the 2019–2025 period. During historical model development, ob...

Higher education expansion policy in Türkiye: Institutional efficiency, structural determinants, and national-level implications for public universities Kulakoğlu, Büşra; Kondakçı, Yaşar; Wigger, Berthold U.; Department of Educational Sciences (2026-6-12) This thesis examines the expansion of Turkish higher education, particularly since 1990s with attention to the “a university for each province” policy by (1) assessing whether this policy intervention has resulted in a HE expansion that meets acceptable levels of institutional efficiency across Türkiye's public universities, (2) identifying economic, social, and technological regional drivers associated with variations in university efficiency, and (3) evaluating how public universities cluster based on tea...
Black-start path planning with a two-stage optimization approach Köroğlu, Pasa Cağrı; Göl, Murat; Department of Electrical and Electronics Engineering (2026-5-13) Power system blackouts are rare, but when they occur, they can severely affect national security, public safety, and economic continuity. The growing integration of renewable generation introduces additional operational challenges for maintaining stability. Therefore, developing effective power system restoration strategies is critical. In the early restoration phase, the system is weak and vulnerable, and the black-start path becomes one of the most critical tasks. A black-start path aims to build an initi...
SEISMIC RESPONSE OF STEEL BUILDINGS WITH BASEMENT CONSIDERING SOIL-STRUCTURE INTERACTION Çeren, Yusuf; Sarıtaş, Afşin; Department of Civil Engineering (2026-4-23) The seismic response of low-rise and mid-rise steel special moment frame buildings with basement levels and raft foundations was investigated with explicit consideration of soil–structure interaction (SSI). The study was motivated by the absence of systematic numerical research on the combined effect of raft foundation flexibility and basement embedment on the seismic demands of NIST archetype steel buildings.4-story and 8-story NIST TN 1863-1 steel SMF archetypes were analyzed using nonlinear time-history ...
Vibration reduction of structures by using negative stiffness and dry friction damping with enhanced slip load capacity and experimental verification Şahin, Recep Alptekin; Ciğeroğlu, Ender; Özgen, Gökhan Osman; Department of Mechanical Engineering (2026-4-24) Dynamic excitations can adversely affect the performance of equipment such as measurement devices, leading to inaccuracies or malfunctions. High excitations reduce the service life of equipment and structures. Exposure to vibration can cause comfort and health issues and degrade the readability of display systems. To mitigate these effects, vibration limits are defined in both military and civil standards. Designing systems that comply with these limits and validating their performance through experimental ...
Investigation of the effect of regular and irregular plan configurations of masonry infill walls on the seismic behavior of deficient RC buildings Gürgit, Atakan; Erberik, Murat Altuğ; Department of Civil Engineering (2026-5-05) In general, masonry infill walls are not considered as structural members in conventional engineering practice, and their strength and stiffness are not directly taken into account in structural design. This approach is commonly accepted as a safe design methodology. However, major earthquakes have demonstrated that irregularities induced by masonry infill walls can lead to global structural failures or local member-level collapses. One of the most common examples is the soft-story irregularity, frequently ...

A HAUNTOLOGICAL READING OF HELEN OYEYEMI’S THE ICARUS GIRL AND STEPHEN GRAHAM JONES’ THE ONLY GOOD INDIANS Çavuş, Zeynep; Korkut Naykı, Nil; Department of English Literature (2026-6-8) This thesis aims to explore spectrality and ghostly manifestations of the inherited past in The Icarus Girl by Helen Oyeyemi and The Only Good Indians by Stephen Graham Jones using the framework of hauntology described by Derrida in his Specters of Marx while also embracing a postcolonial lens on the topic to pursue a critical reading of these two works written respectively by a Nigerian-English and a Blackfeet Native American author. This thesis argues that in both novels, personal and communal traumas of ...
Tools Across Time: Affordance Perception Through Prehistoric, Antique and Modern Tools Koca, Ceyda; Dövencioğlu, Nahide Dicle; Department of Psychology (2026-6-8) Affordance refers to the possibilities for action that objects provide based on their physical characteristics and the perceptual and motor capabilities of individuals.Material culture encompasses all tangible artifacts, objects, and tools created and used by humans, reflecting the dynamic interplay between humans and their environment. Together, these concepts offer a foundational framework for understanding human evolution, particularly through the lens of tool use. Stone tools, the earliest known artifac...

Upcycled Textile Waste as an Interior Design Material Eyüboğlu, Selcen; Börekçi, Naz Ayşe Güzide Z.; Department of Industrial Design (2026-4-20) The rapid depletion of natural resources is among the most significant environmental problems of the time. Industrial activities, urbanization and increasing consumption habits are putting pressure on natural resources, making it difficult for the ecosystem to regenerate itself. The textile industry is among the sectors that consume the most resources and cause the most damage to the environment. The aim of this study is to research the transformation of textile waste into an aesthetic and functional design...

LASER POWDER BED FUSION FABRICATED HASTELLOY X: EFFECT OF HEAT TREATMENT ON MICROSTRUCTURAL EVOLUTION, MECHANICAL PROPERTIES AND HIGH TEMPERATURE OXIDATION BEHAVIOR Özer, Seren; Dericioğlu, Arcan Fehmi; Esen, Ziya; Department of Metallurgical and Materials Engineering (2026-4-22) This work systematically investigated the microstructural evolution, mechanical response, and high-temperature oxidation behavior of laser powder bed fusion (L-PBF)-fabricated Hastelloy X (HX) alloy subjected to solution and aging treatments. In the as-fabricated state, pronounced microstructural and mechanical anisotropy was evident, with the horizontally-fabricated sample exhibiting higher strength but lower ductility compared to the vertically-fabricated counterpart. Solution treatment eliminated tensile...
