Modelling of multiple surface roughness parameters during hard turning: a comparative study between the kinematical-geometrical copying approach and the design of experiments method (DOE)
Mite Tomov, Valentina Gečevska, E. Vasileska

Oznake: matematično modeliranje;modeliranje;hard turning;surface roughness;roughness parameters;mathematical modelling;prediction modelling;design of experiments;DOE;kinematical-geometrical copying;
This paper proposes and applies two different methodologies for modelling the roughness parameters in hard turning. The first method is based on the kinematical-geometrical copying of the cutting tool geometry onto the machined surface including a feedback loop through the parameter of statistic equ ...

Modelling of divertor target plate heat fluxes during intense plasma transients in tokamaks
Ivona Vasileska, Leon Kos, Richard Pitts
Doktorska disertacija
Oznake: fusion reactors;fusion;tokamaks;plasma;divertor;numerical simulations;modelling;
One of the most essential tools for predicting and researching the tokamak scrape-off layer (SOL) is numerical simulation. One of the greatest threats, which can lead to serious, unwanted consequences in next-generation fusion reactors such as ITER, are the transient heat loads on the plasma-facing ...

On the theory of nonlinear landau damping
Leon Kos, Ivona Vasileska, D.D. Tskhakaya
Izvirni znanstveni članek
Oznake: plasmawave analysis;nonlinear Landau damping;parametric instability;collisionless Vlasov–Boltzmann kinetic equation;
An exact solution of the collisionless time-dependent Vlasov equation is found. For the first time in a century, an analytical solution to the one-dimensional time-dependent Vlasov–Boltzmann equation has been found. It has been found that instead of the widely discussed damping, waves are subject to ...

Accelerating Particle-in-Cell simulations in Tokamak Scrape-off Layer using segmented surrogate models
Nikola Vukašinović, Uroš Urbas, Leon Kos, Ivona Vasileska
Izvirni znanstveni članek
Oznake: fusion energy;plasma potential;machine learning;surrogate modeling;extreme gradient boosting method;
Achieving sustainable fusion energy critically depends on accurately modeling complex plasma dynamics within tokamak reactors, particularly in the Scrape-off Layer (SOL), where heat and particles directly interact with reactor walls, influencing reactor performance and component longevity. Particle- ...
