Acceleration of Universe by Nonlinear Electromagnetic Fields [PDF]
, 2016 A new model of nonlinear electromagnetic fields possessing a dimensional parameter $\beta$ is proposed. Electromagnetic fields are considered as the source of the gravitation field and accelerated expansion of the universe is driven by nonlinear ...

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2022 We consider the problem of optimizing the design of a heat sink used for cooling an insulated gate bipolar transistor (IGBT) power module. The thermal behavior of the heat sink is originally estimated using a high-fidelity computational fluid dynamics ...

Eddy current testing of metallic sheets with defects using force measurements [PDF]
Serbian Journal of Electrical Engineering, 2008 The problem of determining defects in structures using eddy current methods was investigated. The goal of this work is to demonstrate that the forces generated by the eddy currents and acting back on the magnet system can be used to detect defects in the

Electromagnetic field and osteogenesis
Vojnosanitetski pregled, 2007 <zakljucak> Poslednjih 50 godina postignuti su odlicni rezultati primenom elektrobioloske stimulacije osteogeneze. Precizno objasnjenje mehanizma dejstva EMP jos uvek nije dato, sto je jedan od razloga razlicitih pristupa i rezultata lecenja prema iskustvima klinicara i eksperimentnih studija.

Transformation media that rotate electromagnetic fields [PDF]
, 2007 We suggest a way to manipulate electromagnetic wave by introducing a rotation mapping of coordinates that can be realized by a specific transformation of permittivity and permeability of a shell surrounding an enclosed domain. Inside the enclosed domain,
