Multiphysics Simulation Methods in Computer Graphics
Computer Graphics Forum, Volume 44, Issue 2, May 2025.Abstract Physics simulation is a cornerstone of many computer graphics applications, ranging from video games and virtual reality to visual effects and computational design. The number of techniques for physically‐based modeling and animation has thus skyrocketed over the past few decades, facilitating the simulation of a wide variety of materials and ...

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...

Dynamics of Variable Stator Vane Adjustment Mechanism Considering the Flexibility of Linkage
International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.The variable stator vane adjustment mechanism plays a vital role in preventing the occurrence of surge due to its complex multistage linkage mechanism. Initially, the flexible body is modeled using the absolute nodal coordinate formulation method, followed by the formulation of rigid–flexible coupled dynamics equations using the Lagrange equations of ...

Thermally activated delayed fluorescence carbazole‐triazine dendrimer with bulky substituents
Aggregate, Volume 5, Issue 1, February 2024.New second‐generation carbazole‐triazine dendrimers were synthesized, and the photoluminescence quantum yield (PLQY) of 81% in the neat film was achieved by substituting the bulky phenylfluorene group at the periphery. Fine‐tuning the locally excited state triplet energy was the key to achieving high PLQY owing to the high reverse intersystem crossing ...

Steady Flow Over a Finite Patch of Submerged Flexible Vegetation
Water Resources Research, Volume 60, Issue 1, January 2024.Abstract An immersed boundary‐finite element with soft‐body dynamics has been implemented to study steady flow over a finite patch of submerged flexible aquatic vegetation. The flow structure interaction model can resolve the flow interactions with flexible vegetation, and hence the reconfiguration of vegetation blades to ambient flow.

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.In this paper, a ground‐based experimental system for solar array active vibration suppression has been established. Firstly, in order to establish an accurate model of the solar array, the solar array is regarded as a flexible cantilevered thin plate, and the corresponding dynamical equations are derived using the absolute nodal coordinate method.

Shape Adjustment of a Large Planar Phased Array Antenna With Nonlinear Cable Actuators
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.Shape adjustment of large planar phased array antennas is significant because the shape distortion of phased arrays can greatly reduce the antenna’s gain in the observing direction. This study selects the inherent diagonal cables driven by motors as actuators, initially used to improve the stiffness of the antenna structure. The shape adjustment can be
