Effect of Flow Intensity and Collars on Scour Depths Around Bridge Abutments Gökmener, Serkan; Altan Sakarya, Ayşe Burcu; Göğüş, Mustafa; Department of Civil Engineering (2023-5-05) In this experimental study, the temporal development of the local scour was studied around semi-circular end and rectangular bridge abutments under unsteady-state clear-water flow conditions in a rectangular sediment chann...
Monitoring and analyzing the sustainability performance of a renewable energy investment with a case study-Tugra HEPP Kalemci, İsmail; Akınoğlu, Bülent Gültekin; Tosun, Kürşad; Department of Earth System Science (2023-5-05) To reach the sustainable development idea, the energy usage and services are in a critical position that most of the announced "Sustainable Development Goals" (SDGs) are somehow related to energy services, especially renew...
Few-shot segmentation by enhanced ensemble of base and meta predictions Kayabaşı, Alper; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2023-4-28) Supervised learning approaches assume that there is a large amount of data available with labels. Since data annotation is a costly and time-consuming task, this assumption loses its validity when there are financial or ti...
ADVANCED METHODS FOR A NOVEL FUSED FILAMENT FABRICATION PROCESS ACCOMMODATING VARIABLE BEAD WIDTH Gharehpapagh, Bahar; Dölen, Melik; Yaman, Ulaş; Department of Mechanical Engineering (2023-4-28) Material Extrusion Additive Manufacturing (MEAM) has revolutionized the production of complex designs while minimizing the amount of effort required due to its simple production pipeline. However, MEAM naturally comes with...
“INVESTIGATING THE POTENTIAL OF GAME ENGINES IN SPACE EVALUATION REGARDING AUTISM SPECTRUM DISORDER (ASD): AN EXPLORATION OF TECHNOLOGY IN DESIGN Amouei, Mohammadhossein; Erkılıç, Mualla; Department of Architecture (2023-4-27) In recent years, researchers in the field of architecture have recognized the importance of creating inclusive and supportive built environments for individuals with Autism Spectrum Disorder (ASD). ASD is a neurodevelopmen...
A REPERTOIRE FOR EXAMINING POTENTIAL OF HYBRIDITY IN URBAN DEVELOPMENT AREAS Atay, Gültekin Doruk; Aral, Hacer Ela; Department of Architecture (2023-4-27) Urban space can be viewed as a dynamic system of interconnections, a complex system of flows and actions. The city is genuinely heterogeneous, conflicting, and ambiguous. In this context, hybridity characterizes difference...
