Biography Download in PDF


Dániel Tüzes is a Ph.D postgraduate student, earned his title in the field of physics in May, 2019. He did his research at Eötvös University, Budapest and at Friedrich Alexander Universität Nürnberg-Erlangen. His research interest includes stochastic simulations and modelling of non-conservative systems and verifying the predictions by experimental investigation. He exploits the efficiency of C++ and the compute power of GPGPU in his stochastic simulations.

Theoretic aspects: describing dislocation systems as a non-conservative N-body problem; using mean-field or local density approximation and finding the corresponding equations of motion. Derive predictions of the constructed models investigable by experiments.

Numerical aspects: solving the partial differential equations describing the equation of motion in a numeric way requires effective coding achieved with C++. Dániel Tüzes is enthusiastic in exploiting the advantages of GPU programming in simulations.

Experimental aspects: the predictions of the models can be verified by experiments using in-situ nanoindentation of single crystals with coupled acoustic emission detection.

Interest keywords: stochastic noise, Monte Carlo simulation, partial differential equations (PDE), correlation analysis, Fourier analysis, linear stability analysis, C++, GPGPU

Miscellaneous

7.2019 - 9.2019
Production leader and manager
Franz-Fertig - DUNAPOL

After a major internal and external attack on the company DUNAPOL, he reconstructed the information technology system at DUNAPOL, commissioned by Franz-Fertig. He investigated the used technology and methods how the company was supposedly working and measured the damages. He recreated the IT infrastructure, including the automated production management system, and by involving database specialist, he repaired the damaged files. With the assistance of the company owner, he coordinated the transportation between the parent company and the subsidiary, ordered and arranged work for the employees and helped managing the acquisitions and the invoicing.

Achieved skills:

  • working in an employee - employer relationship
  • ordering and arranging tasks for workers below him
  • high workload: 12hrs a day, 7 day a week for couple of weeks
  • using German and Hungarian side by side
