In active control of seismic structures, force capacity and time delay of the actuators are generally a restriction in the performance because of using high control forces for big mechanical systems like buildings. Although, a time delay value and a control force limit are considered in the tuning of the controllers, these factors may change according to physical conditions. For that reason, ro...

The present paper studies the heating of coronal loops by linear resonant Alfvén waves that are excited by the motions of the photospheric footpoints of the magnetic field lines. The analysis is restricted to torsionally polarised footpoint motions in an axially symmetric system so that only torsional Alfvénwaves are excited. For this subclass of footpointmotions, the Alfvén and cusp singularit...

Recently developed physics-informed neural network (PINN) has achieved success in many science and engineering disciplines by encoding physics laws into the loss functions of network, such that not only conforms to measurements, initial boundary conditions but also satisfies governing equations. This work first investigates performance PINN solving stiff chemical kinetic problems with equations...
