Physics informed neural networks (PINNs) are a novel deep learning paradigm primed for solving forward and inverse problems of nonlinear partial differential equations (PDEs). By embedding physical information delineated by PDEs in feedforward networks, PINNs trained as surrogate models approximate solution to the without need label data. Due excellent capability describing complex relationships, variety PINN-based methods have been developed solve different kinds such integer-order PDEs,...
Bowel sounds, produced by intestinal peristalsis, are essential for diagnosing gastrointestinal disorders. However, acquiring and analyzing bowel sounds is challenging due to their unpredictable nature individual variability. Biological tissues can affect during propagation, resulting in varying degrees of signal attenuation between the sound source transducer. This study aims develop a numerical model propagation abdominal cavity, focusing on impact different biological layers attenuation....
A singular rail or wheel surface irregularity, such as a squat, insulation joint flat, can cause large wheel-rail impact force. Both the magnitude and frequency content of force need to be correctly modelled because they are closely related formation, deterioration detection irregularities. In this paper, we compare two types commonly used wheel-track interaction models for problems, i.e., beam continuum finite element model. We first reveal differences between forces predicted by due...
Zr N ∕ Ti Al multilayers with various modulation periods and ratios were grown by ion beam assisted deposition. The nanoscale multilayered was confirmed Auger electron spectroscopy. All possess higher hardness than the rule-of-mixture value of monolithic coatings. These properties critically depend on both period ratio. multilayer 6.5nm ratio 2:3 displays highest (>30GPa) critical fracture load (53.3mN). improvements in are likely result strain optimization as evolution layer...
A series of single-grain Y–Ba–Cu–O (YBCO) bulk superconductors were fabricated using a modified infiltration growth (IG) technique, and the morphology feature associated with inner crystallization structure samples was investigated in detail. Experimental observations indicated that YBCO single grains grew much larger increasing slow-cooling time. bended a/c sector boundary observed cross section sample grown for 48 h, which resulted from variations Ra/Rc ratio during process, where Ra Rc...
Spin in frictional rolling contact can cause significant stress, which is the key to understanding and predicting wear fatigue behavior of components, such as wheels, rails, bearings. The lateral creep force arising from spin influences kinematics a wheelset thus vehicles. solution that currently employed field elasticity continuum statics was developed by Kalker uses boundary element method (BEM). In this paper, new approach based on Lagrangian explicit finite (FE) analysis employed. This...
In light of two wheel–rail contact relations, i.e., displacement compatibility and force equilibrium, a newly developed three-dimensional (3D) model for vehicle–track interactions is presented in this paper. This founded on the basis an assumption: rigid contact. Unlike most dynamic models, where interconnections between vehicle track entirely depend forces, subsystems tracks present study are effectively united as entire system with interactive matrices stiffness, damping mass by...
