Rules or Character? Scaling Laws for AI Safety Design
Satoshi Takahashi, Nobuji Kouno, Masaaki Komatsu +1
Artificial Intelligence (AI) safety systems combine character shaping (e.g., Reinforcement Learning from Human Feedback [RLHF], Constitutional AI), which modifies behavioral distri…
Thermodynamically consistent initialization of the Maxwell--Cattaneo---Vernotte heat conduction model: Analytical solutions and engineering applications
Zalán Sándor, Zalán Sándor, Róbert Kovács +1
This paper investigates the numerical initialization of the one-dimensional Maxwell--Cattaneo--Vernotte (MCV) heat conduction model, addressing the critical mathematical challenge…
The piston effect in supercritical fluids investigated via a reversible-irreversible vector field splitting-based explicit time integration scheme
Donát M. Takács, Tamás Fülöp, Róbert Kovács +1
In the vicinity of the liquid--vapor critical point, supercritical fluids behave strongly compressibly and, in parallel, thermophysical properties have strong state dependence. The…
Discovering correlations between metal foam thermal characteristics and non-Fourier behavior
Anna Fehér, Dániel Cseh, Róbert Kovács
Due to their low density and large specific surface area, metal foams are increasingly used as cellular materials that combine excellent structural and thermal properties. Their ce…
