Application of chemical mechanical polishing process on titanium based medical implants
(2017-05)Biomaterials are commonly used as implant materials in the body for dental prostheses, orthopedic applications, heart valves and catheters. Based on the research studies conducted up to date, titanium and its alloys are ... -
Application of large-scale optimization methods in scheduling and routing problems
In this thesis, we consider three different applications of large-scale optimization methods. We focus on the blood donation tailoring problem under uncertain demand in the first problem. In the second one, we propose a ... -
An assessment model for participatory architecture: the example of the solidarity architecture exhibition groups
The relationship between participation and architecture has been discussed for more than fifty years, along with human-oriented design approaches. Scientists from the field of architecture and other related disciplines ... -
Augmenting occupant thermal experience with cyber-physical-social systems : a case study on adaptive vents
(2020-06-11)Buildings use more than 30% of global energy, while 36% of this energy comes from direct combustion of fossil fuels. Hence, buildings constitute a considerable share of CO2 emissions and has a large contribution to climate ... -
Automated maintenance support for data-tier software
Data-tier software includes the data model and business logic of enterprise systems, and it is subject to long-term maintenance. Even though the user interface of these systems can be completely replaced, data-tier software ... -
Automated refinement of models for model-based testing
(2017-07)Model-Based Testing (MBT) enables automatic generation of test cases based on models of a system. It has been successfully applied in various application domains, each of which might introduce specific challenges. In this ... -
Avrupa Birliği mülteci hukuku reformunda düzensiz göçmenlerin statüleri
Göç tarihi insanlık tarihi kadar eskidir. Homo sapiensten günümüz modern insanına değin en temel gayesi hayatta kalmak olan insanoğlu, kıt kaynaklara sahip dünyada sonsuz ihtiyaçlarını karşılamaya çalışmıştır. Bunun sonucunda ... -
Channel modeling and characterization for visible light communications: indoor, vehicular and underwater channels
(2018-06)Despite the increasing attention on visible light communications (VLC) systems, there is a lack of proper visible light (VL) channel models. This is a serious concern since channel modeling is the very first step for ... -
Channel modeling for vehicular visible light communication
The demand for vehicular communication systems has increased since they are considered the key enabling technology for Intelligent Transportation Systems (ITSs). Vehicular communications allow information sharing between ... -
Consumer studies about purchase, repeat purchase and word-of-mouth after deep discount online
(2015-06)Daily deal sites are e-commerce businesses that offer deep discounts (e.g., 50%, 90%) for products and services to consumers through local service providers. These sites increase consumer's buying power and attract more ... -
Corporate sustainability interactions and corporate financial performance
(2017-11)There is a large amount of empirical literature focused on the relationship between corporate sustainability and corporate financial performance. The literature considers firm specific aspects affecting the link but omits ... -

Development of a single-chip visible light communication receiver
The VLC has drawn the attention in the last decade, which is simply based on the data transmission over the visible light (400nm-700nm). It is considered as an alternative to RF-based technologies and offers unlicensed ... -
Development of a solid state spot welding technique for the manufacturing of detect free joints
(2019-06)Development of a Solid State Spot Welding Technique for the Manufacturing of Defect Free Joints.--Friction stir spot welding (FSSW) processing is a recently developed process for joining hard weldability materials, which ... -
Digital maturity measurement based on the stages of digital business transformation a study in the automotive sales and aftersales sector
Digital transformation is the change of socio-economic structures such as business models, supply chains, platforms, or ecosystems as a consequence of the use of digital technology. Consistent with the previous research ... -
Digital oil refinery: utilizing real-time analytics and cloud computing over industrial sensor data
(2018-12-14)This thesis addresses big data challenges seen in large-scale, mission-critical industrial plants such as oil refineries. These plants are equipped with heavy machinery (boilers, engines, turbines, etc.) that are continuously ... -
Dynamic characterization and optimization of additively manufactured TPMS lattice structures
(2021-08-19)Additive manufacturing (AM) has opened new avenues for the manufacturing of structures to achieve challenging engineering tasks. Triply periodic minimal surface (TPMS) lattices, a unique example of such structures, exhibits ... -
Effect of pH on particle agglomeration and radiative transfer in nanoparticle suspensions
(2018-08)Nanoparticle suspensions (NPSs) are solid-fluid mixtures where small dielectric or metallic particles (with sizes <100 nm) used in a base fluid. NPSs have unique and tunable thermo-optical properties, and for that reason ... -
Efficient methodologies for actualizing haptic feedback in consumer electronics
(2021-06-11)There are significant limitations to creating effective haptic illusions in mobile devices such as tablets and smartphones. The main limitations are that these devices are too small in size to accommodate complex actuators ...
