    “The project was really complicated and required exceptional knowledge and expertise in the field of mathematics and programming. Excellent communication and resolving all problems in timely manner.”

  • image of Unknow U. Project 2590693 has been deleted $1550.00 USD

    “You should believe every review that was written before this one. This freelancer is very professional. He delivered my project way before deadline + provided me with step-by-step description of his work. He is also willing to help you and answer all of your questions. I regret that I hired several freelancers before him, because they could not finish my project, and I ended up wasting about 2 months of my time. My recommendation: Hire NAVI1974 even if his bid is higher than everybody else's. Eventually you will save more money and time.”

I have implemented a dynamic variant of the Boundary Control Method (BCM) for reconstruction of speed of sound on semiplane from boundary measurements (inverse problem). The BCM is ab initio approach to multidimensional inverse problems based on ideas of control theory, asymptotic methods, functional analysis and geometry. For a set of test cases (including Marmousi model) the method has demonstrated a good accuracy, see [login to view URL] for details.

I have participated in two research projects related to kinetic modeling of the interaction of helical magnetic perturbations with tokamak plasmas. A numerical code named KiLCA has been developed and successfully applied to analysis of impact of helical magnetic perturbations on plasma configuration in TEXTOR, JET and ITER tokamaks. The results obtained are well known in fusion plasma community and are published in top level scientific journals.
