Abstract: The accurate modelling of solid-rotor induction machines by electromagnetic-field and electric-circuit coupled finite element analysis (FEA) is a very time-consuming task, because induced ...

Researchers in Burkina Faso have assessed the technical feasibility of PV systems near base transceiver stations and have found that solar modules with “optimal” boron doping levels may better resist ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

What is electromagnetic interference and what causes it? The main approaches to filtering out EMI and reducing its impact. How to evaluate EMI filters and what to know about designing them.

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...
