A mesh-free semi-analytical Fourier-based method is presented to evaluate the frequency-dependent losses in windings of solid-state transformers (SSTs) with foil-wound transformers. In employed diffusion equation, which accounts for induced eddy currents, imposed current density and conductivity transformer window area are represented using spatial Fourier series images. As a result, distributi...

This paper describes the stability and Hopf bifurcation analysis of Brusselator system with delayed feedback control in single domain a reaction–diffusion cell. The Galerkin analytical technique is used to present equation composed ordinary differential equations. condition able determine point found. Full maps regions for interacting chemical species are shown discussed, indicating that time d...

Loss of circulation while drilling is a challenging problem that may interrupt operations, reduce efficiency, and contaminate the subsurface. When drilled borehole intercepts conductive faults or fractures, lost manifests as partial total escape drilling, workover, cementing fluids, into surrounding rock formations. control materials (LCM) are often used in mitigation process. Understanding fra...

Over the past few decades, earthquake engineering research mainly focused on the effects of strong seismic shaking. After the 1999 earthquakes in Turkey and Taiwan, and thanks to numerous cases where fault rupture caused substantial damage to structures, the importance of faulting-induced deformation has re-emerged. This paper, along with its companion (Part II), exploits parametric results of ...

This article presents a 3-D semi-analytical model of partially superconducting axial flux modulation machine for the computation density distribution, torque, and eddy-current losses in armature. The coil magnetic field by bulks is calculated solving Maxwell’s equations scalar potential with variable separation method. Using Fourier series analysis convolution theorem, bulk region modeled domai...
