Source-to-source transformation based methodology for graph-parallel FPGA accelerators
(Bilkent University, 2019-08)Graph applications are becoming more and more important with their widespread usage and the amounts of data they deal with. Biological and social web graphs are well-known examples which show the importance of efficient ... -
Efficient parameter mapping for magnetic resonance imaging
(Bilkent University, 2019-08)Balanced steady-state free precession (bSSFP) is a magnetic resonance imaging (MRI) sequence that enables high signal-to-noise ratios in short scan times. However, it has elevated sensitivity to main eld inhomogeneity, ... -
Dynamic adaptive colloidal crystals far from equilibrium
(Bilkent University, 2019-08)Self-assembly has been the center of attention of many researchers from all branches of science. Self-assembly of static structures such as crystals often forms through energy minimization, while dynamic ones need constant ... -
Quantum Monte Carlo simulations of ultracold atomic systems
(Bilkent University, 2019-07)Here, we present our work and findings on ultracold atomic systems. We first present a semi-analytical work on density wave instability (DWI) and collective modes of a bilayer dipolar system of bosons and fermions. We ... -
Universally polarization-insensitive achromatic metasurfaces
(Bilkent University, 2019-07)Transparent optical components constitute the key elements of modern electro-optical systems including optical sensors, displays and imaging systems. The working principle of conventional transparent components rely on ... -
Designers’ finishing material selection considerations in interior spaces
(Bilkent University, 2019-07)This study aims to explore the different considerations contributing to the material selection process in interior architecture discipline and understand designers’ finishing material preferences for interior surfaces, ... -
An exact algorithm for biobjective integer programming problems
(Bilkent University, 2019-07)We propose an exact algorithm to find all nondominated points of biobjective integer programming problems, which arise in various applications of operations research. The algorithm is based on dividing objective space ... -
‘‘Réalta an chruinne caitir fhíona’’: the cult of St. Katherine of Alexandria in Late Medieval Scotland
(Bilkent University, 2019-07)This thesis succinctly investigates the chronological traces and the historical development of the cult of St. Katherine of Alexandria in Late Medieval Scotland. The main argument of this study evolves around why possibly ... -
Written complexity developmental stages of Turkish EFL learners in argumentative writing
(Bilkent University, 2019-07)This study aimed (a) to identify written grammatical complexity (i.e., syntactic complexity) stage(s) and grammatical functions of undergraduate Turkish EFL students based on Biber et al.’s (2011) framework for grammatical ... -
Do women misreport domestic violence: evidence from couple data
(Bilkent University, 2019-07)The literature on domestic violence against women excessively employs survey data in which there is only women side of the violence. In this study by benefiting from a couple data, we use both men and women reporting of ... -
Aza-Nazarov cyclization reactions using anion exchange strategy
(Bilkent University, 2019-07)Although Nazarov reaction is a synthetically useful route for the synthesis of five-membered rings, there are a very limited number of studies on its analogous process producing N-heterocycles; aza-Nazarov reaction, and ... -
A branch and cut algorithm for the inventory routing problem
(Bilkent University, 2019-07)The inventory routing problem arises in vendor managed systems where products are distributed from a supplier to a set of retailers by a homogeneous eet of capacitated vehicles. The routes of the vehicles and the ... -
Pd-catalyzed synthesis of substituted heteroaromatic fluoranthene analogues and studies towards the total synthesis of truncatone C and imeluteine
(Bilkent University, 2019-07)Fluoranthenes represent an important class of polycyclic aromatic compounds with important applications in modern chemistry and materials science. In addition to being present in the structural core of a variety of fungal ... -
Privacy-preserving protocols for aggregate location queries via homomorphic encryption and multiparty computation
(Bilkent University, 2019-07)Two main goals of the businesses are to serve their customers better and in the meantime, increase their pro t. One of the ways that businesses can improve their services is using location information of their customers ... -
Teaching Turkish to Syrian refugee students: teacher perceptions
(Bilkent University, 2019-07)This study explores teachers’ perceptions, challenges and needs in teaching Turkish to Syrian refugee students. Content analysis design was used for this qualitative study to gain insights from interviews with three Turkish ... -
Multimodal video-based personality recognition using Long Short-Term Memory and convolutional neural networks
(Bilkent University, 2019-07)Personality computing and affective computing, where recognition of personality traits is essential, have gained increasing interest and attention in many research areas recently. The personality traits are described by ... -
The conditions and methods of the land travels of the Ottoman subjects during the pre-modern era
(Bilkent University, 2019-07)Traveling in the Ottoman Empire during the pre-modern times was challenging and dangerous for everyone, but much so for civilians. Furthermore, the central authority discouraged the mobility of civilians, and wanted them ... -
A comparative study on indoor soundscape in museum environments
(Bilkent University, 2019-07)The aim of this study is to understand how visitors perceive and compare the soundscapes of different museum environments. To reach this goal, physical parameters as acoustic measurements, and perceptual data as questionnaires ... -
Iterative fitting approach to CR-MREPT
