The emerging destructive Technologies such as big data, internet of things (IoT), cloud have revealed the Industry 4.0 revolution. Although Industry 4.0 technologies have very important benefits to the manufacturing sector, various obstacles may arise against the application of these technologies. The aim of this thesis is to make detailed studies on the Industry 4.0 revolution and to reveal the obstacles that may arise during the application of Industry 4.0 technologies to the Turkish manufacturing sector. Interpretive Structural Modeling (ISM) technique was used while establishing the relationship between the barriers in front of IE 4.0 adaptation. ISM Framework was obtained with the findings obtained as a result of the study.

Recent developments in IT and Analytics have created a multitude of technologies for analytics professionals to use. This technology variety complicates the technology selection process. When improper technologies are selected, analytics teams face problems, inefficiencies, and technical debt. To solve this problem, this thesis proposes a systematic technology selection approach and tests it on a case study.

With the widespread use of cloud computing in software development processes, many industries have started to use cloud computing. Within the scope of this study, a framework has been created to enable the use of cloud computing in the defense industry. While creating the framework, all the constraints required by the defense industry were complied with and the appropriate cloud structure was selected. At the end of the study, the use of the framework was confirmed by the defense industry employees.

This research aims to enhance the perceptual quality of adversarial attacks, regardless of the type of attack used. To achieve this, the study proposes an integration of two seperate attack independent techniques. The first technique, called Normalized Variance Weighting, applies a variance map to intensify the perturbations in high variance areas. The second technique, called the Minimization Method, minimizes the perceptual distance between the benign and adversarial example iteratively. Integrated Method, with the first method applied during the attack and the second method applied after the attack has quantifically the best visual quality.

This thesis solves the 3D mesh segmentation problem from a different perspective. This perspective contains a data-centric approach with unsupervised learning. This means that 3D mesh segmentation mapping plays a key role in terms of a data-centric approach. We provide a mapping architecture using the node2vec model that also solves the curse of dimension and transforms 3D mesh data into an embedding vector. Segmentation was obtained using the K-Means clustering algorithm using this embedding vector. Additionally, we provide a new strategy that evaluates the graph embedding vector and a new inertia method calculated on 3D mesh data, geodesic inertia.

Genomic sequencing technologies opened a new era for genetic disorder diagnostics. ​Currently, in over 80% of the cases, the genetic etiology of the diseases can be ​determined by identifying the causative variations. In this study, we have utilized two next-generation sequencing technologies, Ion-Torrent and Illumina, for a rare disease family with two siblings sharing similar symptoms. In addition to comparing technologies, different assemblies of human reference assemblies are analyzed and the benefits of all are discussed for revealing the variants of unsolved rare disease cases.

The main purpose of this thesis is to investigate the potential effects of the gaze bahavior modeling. To that end, experiments were conducted with human participants in the form of a mock-up job interview setting, where a robot avatar programmed with pre-planned gaze behavior in reference to the model was in charge as the interviewer. The eye-tracking data of the participants were collected and analyzed. The eye-tracking results were compared with traditional Human-Robot Interaction survey data along with the TF-IDF (Term Frequency-Inverse Document Frequency) analysis of the post-experimental oral evaluations.

In an attempt to understand the semantics of –(y)Iş better, this thesis aims to systematically distinguish imperfect -(y)Iş nominals from perfect -(y)Iş nominals, manner-denoting -(y)Iş nominals from eventuality-denoting ones, identify the types of eventuality denoted, and identify the factivity status of eventuality-denoting -(y)Iş nominals. We suggested sets of tests for each category, and we applied these tests to a sample set of data to demonstrate that they can be used to reliably and accurately make these distinctions.

An outcome of taking poor decisions or choosing easier solutions for faster code delivery is technical debt. There is a gap in the field to assist managing technical debt for software development companies that work with software as a service applications. This thesis aims to specify and categorize the technical debt present in organizations using software as a service applications, by studying the processes for categorizing technical debt, and specifying the causes and issues arising due to this debt.

When choosing a route in orienteering, it is important to combine physical endurance with mental processes and the ability to adapt to the environment and optimize them correctly. In this study, the components affecting route selection were investigated. For this purpose, the data obtained from athletes through GPS containing watches were examined with quantitative and qualitative research methods. Then, a model based on spatial data was created to find the shortest paths and to compare the compatibility with the behaviors of athletes, and the relation of route selection decisions with some specified cognitive paradigms was questioned.
