본 논문에서는 동적 네트워크 환경에서 이기종 에이전트 간 실시간 지식 전이를 활용하는 적응적 강화학습 알고리즘을 제안한다. 기존의 중앙집중식 학습과 분산 실행 방식은 중앙 서버와 모든 에이전트의 안정적 연결을 전제하므로, 불안정한 네트워크에서는 학습과 전이가 제한된다. 본 연구는 부분 연결 상황에서도 관측 가능한 정보만 활용하고, 에이전트 간 유사도 기반 전이 그래프를 통해 선택적으로 지식을 ...

The thermo-mechanical behavior of the interface zone in nuclear reactor buildings is crucial for structural safety at high temperatures. In this study, two 1:10 scale prototypes were designed and fabricated to investigate ...

The seismic correlation of component responses and capacities significantly affects the risk of nuclear power plants (NPPs). Despite several studies addressing this seismic correlation, challenges with accuracy and efficiency ...

Challenges still exist in predicting vortex-induced vibrations of tube bundles due to the difficulty in determining fluid forces between tubes. We effectively predict the vortex-induced vibrations of tube bundles through ...

In this study, a non-intrusive reduced-order modeling framework based on proper orthogonal decomposition (POD) and artificial neural networks (ANNs) is developed to predict the time-dependent nonlinear fracture behavior ...

Linear accelerators provide significant advantages for hadron therapy, including fast energy modulation and reduced activation compared to circular machines. Although Side-Coupled Drift Tube LINACs (SCDTLs) are commonly ...

Parametric instabilities have been long known as a major space-charge halo mechanism and studied intensively. With realistic distributions, for the first time we confirm that high-order parametric instabilities other than ...

This paper proposes a novel adaptive acceleration method based on online Incremental Orthogonal Component Analysis enhanced Dynamic Mode Decomposition (IOCA-DMD) and applies it to a self-developed Nodal Expansion Method ...

The Ultra-fast Transient Experimental Facility (UTEF), designed for low emittance and high intensity demands enhanced algorithmic stability for RF control. This paper presents a simulation study of an active disturbance ...

Silicon carbide (SiC) is an important material for nuclear applications, serving as cladding in fission reactor fuels and proposed for the first wall/blanket of fusion reactors, environments where significant helium (He) ...
