Numerical Studies for Petrol and Gas Reservoir Problems The focus of this project will be mathematical models to describe petroleum or gas reservoir simulations. For such a kind of problems, permeability is desperately needed in the oil industry, however, it is hard to accurately measure the permeability field in the earth, due to the large area of oil reservoir and complicated earth structure. Therefore, identification of permeability parameter is crucial for the efficiency of the mathematical models. Since the classical (deterministic) partial differential equations cannot express the behavior of the physical problem completely, the permeability parameter is represented as a random field. The mathematical modelling of such a kind of problems corresponds to basically unsteady convection diffusion equations. Therefore, our first interest will be numerical investigation of the time-dependent convection diffusion equation with random input data. Then, we extend the concept to the stochastic optimal control problems. Lastly, by constructing the random data parameters as permeability with the help of the original data, the effect of the mathematical simulations can be observed. |

Evaluation of Credit Risk Using Machine Learning Techniques in Banking Sector In this project, credit scoring methods that are used in literature for credit risk assessment are taken into account. These methods do have great importance for lending institutions such as banks. Based on real life realizations, for credit scoring at first we aim to determine the significance of each variable in credit scoring. We test different combination of them to increase the performance of methods. |

A Real-Time Working Prototype for Algorithmic Trading and Financial Tools In this work, it is planned to create a real time algorithmic trading prototype. This prototype is designed as a system that generates data in itself and uses this data, and also can use real market data when necessary. Models in this system will generate artificial market data and portfolio analysis and optimization techniques will be examined using algorithmic trading techniques. In this system, various areas of finance engineering such as pricing, simulation, risk analysis and optimization wil be used. The prototype is designed as a flexible system in that modules can be developed and new modules can be added. |
