Representations in design computing through 3-D deep generative models Çakmak, Başak; Öngün, Cihan (2024-12-10) This paper aims to explore alternative representations of the physical architecture using its real-world sensory data through artificial neural networks (ANNs). In the project developed for this research, a detailed 3-D po...
DEVELOPING A FRAMEWORK TO EVALUATE THE USABILITY OF VIRTUAL AND MIXED REALITY ENVIRONMENTS TO PRACTICE MODEL-BASED SYSTEMS ENGINEERING Karataş, Kaan; Sürer, Elif; Department of Modeling and Simulation (2024-11-26) Systems Engineering is an interdisciplinary engineering field that focuses on the identification of the required components of a product and their specifications to achieve the purpose or objective. The emergence of Model-...
landusemix: A Python package for calculating land use mix Akyol, Mehmet Ali; Duzgun, Sebnem; Baykal, Nazife (2024-09-01) Integrating different land uses within a geographic area is essential to urban planning and development. Accurate and fast land use mix (LUM) measurement is necessary for evaluating urban diversity and sustainability. In t...
UNDERSTANDING THE INFLUENCE OF ORGANIZATIONAL CULTURE ON TECHNICAL DEBT ACCUMULATION AND MANAGEMENT ÇAĞLAYAN, DİLEK; ÖZCAN-TOP, ÖZDEN; Department of Information Systems (2024-8) Technical Debt (TD) is a metaphor to describe the cost of additional work caused by choosing a non-ideal solution in software development. Over time, TD accumulates and returns as a liability, necessitating significant ref...
KNOWLEDGE GRAPH AUGMENTED MULTI-HOP QUESTION ANSWERING USING LARGE LANGUAGE MODELS Sağlam, Barış Deniz; Koçyiğit, Altan; Department of Data Informatics (2024-8) This thesis explores the use of small to medium-sized large language models (LLMs) for multi-hop question answering. As computational resources and latency present significant constraints in real-world applications, smalle...
A novel content-based retrieval system for hyperspectral remote sensing imagery Ömrüuzun, Fatih; Yardımcı Çetin, Yasemin; Leloğlu, Uğur Murat; Department of Information Systems (2024-5-27) Due to the increased use of hyperspectral remote sensing payloads, there has been a rise in the number of hyperspectral remote sensing image archives, resulting in a massive amount of collected data. This highlights the ne...
Semi-Blind Estimation of Direct-to-Reverberant Energy Ratio Using Residual Energy Test Statistics GÖKÇE, ALİ; Hacıhabiboğlu, Hüseyin (2024-04-14)
Exploring early markers of fibrosis progression in metabolic dysfunction–associated steatotic liver disease in Turkiye Kahraman, Deniz Cansen; Sinoplu, Esra; ATALAY, RENGÜL; İDİLMAN, RAMAZAN (2024-02-17)
A REFERENCE ARCHITECTURE FOR SIMULATION-BASED DIGITAL TWINS Kandaz, Murat; Koçyiğit, Altan; Department of Software Management (2024-1-21) Digital twins can be based on data, physics, rules, behaviors, and geometry models/features. Together with the conventional data-based approach that has been used for decades, other models that are generally based on engin...
RETHINKING THE CENTRALIZATION OF IT GOVERNANCE: VOICES OF SENIORS FROM A LARGE TECHNOLOGY ORGANIZATION Sari, Burcin; Özkan Yıldırım, Sevgi (2024-01-01) As some organizations become larger and grow with respect to size, they aim to centralize their IT governance to improve relevant effectiveness and efficiency. However, it is still not fully clear whether this kind of tran...
