Abstract As hydrogen is touted as a key player in the decarbonization of modern society, it critical to enable quantitative (H) analysis at high spatial resolution and, if possible, atomic scale. H has known deleterious impact on mechanical properties (strength, ductility, toughness) most materials that can hinder their use part infrastructure hydrogen-based economy. Enabling mapping including local concentration analyses specific microstructural features essential for understanding multiple...
The Seventh National Population Census, recently conducted in 2020, reported the most up-to-date information on size, structure, and distribution of China's population. results showed that gender imbalance China is still severe compared with international standard. With aim understanding what has contributed to imbalance, this study examined a range potential influencing factors measured extent which they have affected sex structure. We gathered data from 3100 citizens (100 surveys each...
In response to the limitations observed in critical infrastructure protection systems, particularly their lack of adaptabilit y dynamic and complex environments, this paper introduces an intrusion behavior strategy analysis method utilizing enhanced Proximal Policy Optimization (PPO) algorithm. This accounts for decision-making attackers who have access partial information, enabling it effectively simulate authentic strategies. By leveraging feedback fro m environmental interactions as a...
The physical protection systems of Nuclear Power Plant are utilized to safeguard targets against intrude by attacker. As the methods employed attackers become increasingly complex and diverse, there is an urgent need identify optimal defense strategies interrupt adversary intrusions. This paper focuses on studying security personnel intrusions utilizes evolutionary game approach select decisions for systems. Under assumption bounded rationality both attacker defender, constructs replication...
A physical protection system (PPS) is used to protect a nuclear power plant (NPP) for preventing the material and critical infrastructure from theft, robbery, illegal transfer, sabotage. An integrated platform analysis design (IPAD) of PPS was proposed by authors' previous work. By combining functions 3-D modeling with automatic 2-D drawing generation, IPAD will provide designers comprehensive visualized information in one which enable quick convenient PPS. This paper introduces reliability...
Virtual reality technology has been widely used in the field of nuclear and radiation safety, dose rate computing virtual environment is essential for optimizing protection planning work radioactive-controlled area. Because CPU-based gamma takes up a large amount time power voxelization volumetric radioactive source, it inefficient limited its applied scope. This study to develop an efficient code apply into fast simulation. To improve efficiency point kernel algorithm reference (Li et al.,...
In the present work, atomic interactions among Cu, Al, and Ni elements in body‐centered cubic (BCC) ‐iron matrix, focusing on formation mechanism of nano‐sized core–shell Cu precipitates, are investigated. this study, using a combination atom probe tomography, density‐functional theory (DFT) calculations, molecular dynamics simulations, insights into atomic‐scale migration tendencies these supersaturated solid solution surrounding precipitate martensite phase medium‐Mn steel provided....
A physical protection system (PPS) is used for the of critical facilities. This paper proposes a structure analytic hierarchy approach (SAHA) hierarchical evaluation PPS effectiveness in infrastructure. SAHA based on traditional analysis methods "estimate adversary sequence interruption, EASI". community algorithm building model. applied to cluster associated elements topological design complicated with graphical vertexes equivalent elements.
As a clean and safe energy, nuclear power plays an important role in solving the increasingly prominent environmental problems world. Researches on reliability analysis risk assessment for safety operation of Nuclear Power Plants (NPPs) have been paid much more attention due to several accidents past decades. GO-FLOW is methodology analyzing dynamic systems with common cause failures (CCFs), man-machine failures, time-dependent mission issues. The traditional presents set operators each...
As hydrogen is touted as a key player in the decarbonization of modern society, it critical to enable quantitative H analysis at high spatial resolution, if possible atomic scale. Indeed, has known deleterious impact on mechanical properties (strength, ductility, toughness) most materials that can hinder their use part infrastructure hydrogen-based economy. Enabling mapping, including local concentration analyses specific microstructural features, essential for understanding multiple ways...
The present work investigates the atomic interactions among Cu, Al, and Ni elements in bcc-iron matrix, focusing on formation mechanism of nano-sized core-shell Cu precipitates. Using a combination atom probe tomography (APT), density functional theory (DFT) cal-culations, molecular dynamics (MD) simulations, study provides insights into atomic-scale migration tendencies these supersaturated solid solution sur-rounding precipitate martensite phase medium-Mn steel. results show that Al atoms...
An effective Physical Protection System (PPS) requires methodologies and tools to automatically evaluate the PPS effectiveness, provide suggestions or strategies for further redesign optimizations, assist NPPs conduct training their staffs.
