61. Simulating gold resonant nano-antennas for nano-fusion

Istvan Papp (Wigner FK)

Modern theoretical fusion research is powered by plasma simulations, inertial confinement fusion usually involves particle-in-cell (PIC) methods containing lasers interacting with charged particles. Here we show a simple kinetic model of resonant gold nanoantennas both in vacuum and a monomer used as fillings in dentistry. The model manages to describe well qualitatively and quantitatively the...

Lecture

When light travels through a medium with a changing refractive index, it gets bent towards its higher values. This can produce upside down "mirror" images of a scenery in deserts, over heated roads or above bodies of water. We built a model for the temperature profile based on measurement data, from which we calculated the refractive index of air using another model. We implemented a computer...

38. Parallel computing for determining stable parameter domain in mechatronic applications

Mr Tamás Haba (Budapest University of Technology and Economics)

21/06/2022, 14:50

The field of mechatronics engineering integrates mechanical systems and control; therefore, the main challenges of both subfields appear simultaneously. A typical task in mechatronics is position control, where the main goal is to reach the desired position or track a predefined trajectory. The primary design task is to determine the stability domain of the control parameters where the...

52. Full Core Pin-Level VVER-440 Simulation of a Rod Drop Experiment with the GPU-Based Monte Carlo Code~GUARDYAN

David Legrady (Dr.)

Lecture

Targeting ultimate fidelity reactor physics calculations the Dynamic Monte Carlo (DMC) method simulates reactor transients without resorting to static or quasistatic approximations. Due to the capability to harness the computing power of Graphics Processing Units, the GUARDYAN (GpU Assisted Reactor DYnamic ANalysis) code has been recently upscaled to perform pin-by-pin simulations of power...
