The paper deals with finite element model for analysis of electromagnetic forming process of thin metallic sheets. The investigation starts with the FLUX simulation of transient electromagnetic field phenomena, continues with a transient structural analysis using ANSYS Structural under loads previously evaluated and ends with an ANSYS Multiphysics fully coupled analysis. The paper emphasizes th...

The interaction between transferred-electron effect and base widening under transient conditions in III-V heterojunction bipolar transistors is considered. Modification of the collector field profile with an n+ doping spike is shown to cause a time delay for the onset of Kirk effect creating conditions for the inception of charge instabilities. Numerical simulations suggest the possibility of s...

Transient lunar phenomena (TLPs) have been reported for centuries, but their nature is largely unsettled, and even their existence as a coherent phenomenon is still controversial. Nonetheless, a review of TLP data shows regularities in the observations; a key question is whether this structure is imposed by human observer effects, terrestrial atmospheric effects or processes tied to the lunar s...
