Enhancement of 360-video experience during head motion
Efficient use of available bandwidth is vital when streaming 360-degree videos, as users rarely have enough bandwidth for a pleasant experience. The combination of viewport-dependent streaming (VDS) and rate adaptation is ... -
N-hop influence maximization problem under deterministic linear threshold model
The Influence Maximization Problem (IMP) finds a set of highly influential nodes within a social network in order to maximize the spread of influence. We consider that people can have influence on their direct (1-hop), ... -
Effect of different surface treatments on the tensile and wear behavior of Inconel 625 superalloy and aisi 321 stainless steel
AISI 321 stainless steel and Inconel 625 superalloy are utilized in an extensive range of applications such as aircraft engines, nuclear powerplants and industrial furnaces due to their excellent mechanical properties at ... -
Server and client-side algorithms for enhancing adaptive streaming
HTTP adaptive video streaming is a technique widely used on the internet today to stream live and on-demand content. Server and client-side algorithms play an important role in improving user experience in terms of metrics ... -
An applicable approach to automate customer complaints
Customer complaint management is critical and time-consuming process for institutions. For an effective management and increased customer satisfaction, developing an instant and automated reply mechanism is essential. This ... -
Set-covering based heuristic approaches for the problems from the printing industry
In this thesis, we focus on two different planning production problems coming from the printing industry. The first problem is the label printing problem and the second one is a variant of the cover printing problem. In ... -
Rolling look-ahead approaches for optimal classification trees
Classification trees have gained tremendous attention in machine learning applications due to their inherently interpretable nature. Current state-of-the-art formulations for learning optimal binary classification trees ... -
Metaheuristic approaches for maximum blood collection problem
Thanks to recent technological and medical advances, blood components can now be extracted from whole blood after a donation. One of such components is the platelet, which has a wide range of uses in medical fields, including ... -
Scheduling and routing of chronic dialysis patients in the aftermath of a disaster
Disasters have devastating effects on patients with chronic diseases who need regular treatments to preserve their health. In this thesis, we focus on developing effective, fast and joint solution methodologies to support ... -
Demand and supply planning for Covid-19 vaccine in Turkey with an anti-vaccine survey
The Covid-19 virus, which affects many people, continues in a very contagious state. Vaccination is necessary to end this pandemic period, which everyone wants to end as soon as possible. The studies in the literature ... -
Reducing open vial wastage with lateral transshipment in COVID-19 vaccine administration
After the discovery and production of vaccines for the immunization against COVID-19 pandemic, mass vaccination programs are launched across the world. One of the main challenges faced during the COVID-19 mass vaccination ... -
Open-end bin packing problem with conflicts
In this thesis study, we focus on a new variant of the famous Bin Packing Problem (BPP) called the Open-End Bin Packing Problem with Conflicts (OEBPPC) which combines the Open-End Bin Packing Problem (OEBPP) and the Bin ... -
Implementing artificial neural network based gap acceptance models in the simulation model of a traffic circle in SUMO
The impact of various operational and design alternatives at roundabouts and traffic circles can be evaluated using microscopic simulation tools. Most microscopic simulation softwares utilize default underlying models for ... -
Effects of unbonded mild steel on seismic performance of unbonded post-tensioned precast concrete shear walls
Seismic energy dissipation of precast concrete lateral force-resisting systems constructed based on non-emulative or jointed connections is very limited since these systems experience little to no damage during seismic ... -
Return prediction in turkish stock market via machine learning
In this study I compare machine learning methods for predicting the stock returns of individual Turkish stocks listed in the Istanbul Stock Exchange (Borsa Istanbul). As the main machine learning model I use the Instrumented ... -
Determinants of liquidity adequacy ratio: An empirical study on Turkish banks
Liquidity and liquidity risk is a phenomenon that has important consequences in the management of banks. In addition, liquidity risk has an important role in banking crises. With the new regulations created, liquidity ... -
Valuation of fixed income securities and estimation of term structure on international bond market using machine learning techniques
In this study, I focus on predicting bond risk premia in Turkish Eurobonds market using machine learning methods. Machine learning uses statistical learning techniques to gather useful structures of a data set without being ... -
Adaptive MIMO free space optical communication systems
Free space optical (FSO) enjoys the high data rate of optical spectrum and have also the flexibility of RF links. FSO systems provide many advantages to the line of sight wireless communication technology. With the recent ... -
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 ... -
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 ...
