An investigation into fluid flow and heat transfer of high frequency synthetic jets for electronics cooling
(2016-04)Modern electronics have been decreasing in size for decades, so their cooling systems must continually improve in efficiency too. In particular, compactness is vital, which is challenging because typical thermal management ... -
An investigation into hydrophobic micro-textured surfaces on heat transfer and surface wetting phenomenon during vapor condensation
(2018-12-28)Efficiency and performance of a system that involves condensation process have been one of the primary considerations over the last decades for a number of applications including thermal management systems such as vapor ... -
Investigation of corrosion in oil pipelines through surface nano-treatment
(2020-01)Corrosion is the unintentional and degradation of a material caused by the reaction of that material with its environment and a natural possible hazard correlated with gas and oil generation and transportation facilities. ... -
Investigation of flame characteristics in a turbulent premixed combustion
(2018-10)In this thesis, the turbulent flame closure (TFC) model and coherent flame model (CFM) of turbulent premixed flames as steady state flow are used. In addition, large eddy simulation (LES) model as unsteady state flow is ... -
Liquidity in the emerging market local currency bond market: measurement,commonality, and supply of risk capital
(2016-06)Major emerging markets sovereigns have started financing a significant component of their budget deficits issuing local currency (LC) bond, reaching to the total outstanding size over 5 trillion dollar almost half of the ... -
Macroeconomic fundamentals and emerging market asset prices
(2017-06)This thesis consists of three chapters which make empirical contributions to the field of emerging markets xed income, real estate and nancial markets. First chapter entitled 'Macroeconomics Fundamentals and Emerging ... -
Mechanical performance of layered metallic composites processed by accumulative roll bonding
(2019-08-20)Mechanical Performance of Layered Metallic Composites Processed by Accumulative Roll Bonding.--Multi-layered metal composites have received considerable attention due to their advanced mechanical and physical properties. ... -
Mobility management and resource allocation strategies for visible light communication networks
(2021-05-11)There has been a growing interest in Visible Light Communications (VLC) in recent years. The existing works in the literature on point-to-point VLC systems are well established, and especially the studies on physical layer ... -
Modeling and optimization of chemical mechanical polishing of semiconductor materials
Chemical mechanical polishing (CMP) is a process of planarization of metal and dielectric surfaces typically in microelectronic devices manufacturing. Planarization is achieved by removing material from the wafer surface ... -
Nano-scale chemically modified thin film characterization for chemical mechanical planarization applications
(2015-01)The aim of the microelectronics industry has historically been achieving increasing functionality through decreasing the device sizes while simultaneously reducing the unit manufacturing costs. This objective has been ... -
Near- and far-field thermal radiation in metamaterials and the development of NF-RT-FDTD algorithm
(2016-06)In this dissertation, analysis of near-field regime of thermal radiative transfer in metamaterials supporting surface phonon polaritons (SPhPs) is given. Solutions of electromagnetic fields at subwavelength distances are ... -
Performance evaluation and experimental verification of vehicular visible light communication
Araç geliştirme, gelecekteki bazı uygulamalarını desteklemek için büyük ölçüde veri iletişimine aktarır. Araç müfrezesi ve otonom araçlar (AV), bu on yılda ticari olarak temin edilebilecek uygulamalardan bazılarıdır. Bu ... -
Performance, managerial skill and factor exposures in commodity trading advisors and managed futures funds
(2016-09)Understanding risk is important. Prior to 2008, as the yields on safe assets hit rock bottom, investors turned their focus to an alphabet soup of more complex instruments. These complex securities were rated AAA, they ... -
Professional demarcation in new media art in Turkey
In a world where the Post-media condition has rendered the artistic media hierarchies obsolete, New Media Art continues to exist as a professional territory with ambiguous boundaries. The term refers to a community of ... -
Quantifying the spillover of green products on consumer attitudes and umbrella brand sales
(2017-06)Despite growing consumer attention to the environment, it is still unclear how and how much companies benefit from their large investments in 'green' products. This paper quantifies the positive spillover of sustainable ... -
Radiative cooling by spectrally selective materials for building
(2018-01-03)Buildings utilize more than one-third of the total energy consumed in counties within the Mediterranean climate zones like in Turkey. Particularly during the summer months, the absorption of solar energy by the buildings ... -
Robust estimation of term structure and implied volatility in emerging markets
(2016-07)Despite powerful advances in interest rate curve modeling for data-rich countries in the last 30 years, comparatively little attention has been paid to the key practicalproblem of estimation of the term structure of interest ... -
Runtime specialization and autotuning of sparse matrix-vector multiplication
(2015-12)Runtime specialization is used for optimizing programs based on partial information available only at runtime. In this thesis, we present a purpose-built compiler to quickly specialize Sparse Matrix-Vector Multiplication ... -
Runtime verification of internet of things using complex-event processing (RECEP)
(2018-06)Increase in the computing power and memory accompanied with decreasing architectural footprints has enabled conquering new frontiers in proliferation of technology in the next industry revolution. More autonomous systems ... -
Scalable analysis of large-scale system logs for anomaly detection
(2019-05-30)System logs provide information regarding the status of system components and various events that occur at runtime. This information can support fault detection, diagnosis and prediction activities. However, it is a ...
