    (Ieee, 2018) Dogdu, Erdogan; Ozbayoglu, Murat; Yazici, Ali; Karakaya, Ziya
    Big Data is one of the most commonly encountered buzzwords among IT professionals nowadays. Technological advancements in data acquisition, storage, telecommunications, embedded systems and sensor technologies resulted in huge inflows of streaming data coming from variety of sources, ranging from financial streaming data to social media tweets, or wearable health gadgets to drone flight logs. The processing and analysis of such data is a difficult task, but as appointed by many IT experts, it is crucial to have a Big Data Implementation plan in today's challenging industry standards. In this study, we performed a survey among IT professionals working in the public sector and tried to address some of their implementation issues and their perception of Big Data today and their expectations about how the industry will evolve. The results indicate that most of the public sector professionals are aware of the current Big Data requirements, embrace the Big Data challenge and are optimistic about the future.

    Makine Öğrenmesi Algoritmalarının Oyun Seviyelerinin Zorluklarının Belirlenmesinde Kullanılması
    (2020) Şahbenderoğlu, Turan Ozan; Karakaya, Ziya
    In game design, adjusting difficulty is one of the key aspects of financial success. However, this task is costly since it is time-consuming. In the literature, there are very limited studies according to determining the game difficulty. Instead, almost every study is about difficulty adjustment which skips the determining process. This thesis aims to develop a game environment to observe if the machine learning can determine the difficulty of a game and the game levels. For this purpose, a game with five different levels from easy to hard is developed in Unity Engine. A machine learning agent that uses reinforcement learning is also developed and each game level used as learning environment of the agent. In general, the learning process shows that the Cumulative Reward of the agents is decreased as levels become harder. The complexity of the game significantly decreases Cumulative Rewards. The results of this thesis have shown that those level difficulties of a game can be determined by comparing the reinforcement learning agent's performance on collecting rewards in the training area. In other words, machine learning algorithms have a big potential to support the game design phase of the game development process when it comes to determining the level of difficulties.

    Need for a Software Development Methodology for Research-Based Software Projects
    (Institute of Electrical and Electronics Engineers Inc., 2018) Cereci,I.; Karakaya,Z.
    Software development is mostly carried by a group of individuals. Software development methodologies are heavily utilized to organize these individuals and keep track of the entire software development process. Although previously proposed software development methodologies meet the needs of the industry and the firms, they are not usually suitable for research-based software projects that are carried by universities and individual researchers. In this paper, we aim to show the necessity of a new software development methodology for research-based problems carried by universities. The literature review will show the differences between industry and university software projects from certain aspects. These findings will be supported by the authors own research on the area. This qualitative research involves collecting data through interviews and applying Grounded Theory to better understand the development process. © 2018 IEEE.

    A Parallel Boundary Element Formulation for Tracking Multiple Particle Trajectories in Stoke's Flow for Microfluidic Applications
    (Tech Science Press, 2015) Karakaya, Z.; Baranoglu, B.; Cetin, B.; Yazici, A.; Baranoğlu, B.; Computer Engineering; Software Engineering
    A new formulation for tracking multiple particles in slow viscous flow for microfluidic applications is presented. The method employs the manipulation of the boundary element matrices so that finally a system of equations is obtained relating the rigid body velocities of the particle to the forces applied on the particle. The formulation is specially designed for particle trajectory tracking and involves successive matrix multiplications for which SMP (Symmetric multiprocessing) parallelisation is applied. It is observed that present formulation offers an efficient numerical model to be used for particle tracking and can easily be extended for multiphysics simulations in which several physics involved.
