Machine learning (ML) is the study of computational methods for improving performance by mechanizing acquisition knowledge from experience. As a modern data-driven optimization and applied regression methodology, ML aims to provide increasing levels automation in engineering process, replacing much time-consuming human activity with automatic techniques that improve accuracy and/or efficiency d...

This paper addresses the latest advancements in the application of computational electromagnetics and smart telemetry systems to the development of a retinal prosthesis to restore the sight in the blind. Numerical methods and models have been developed to a) accurately characterize the thermal increase in the human head and eye associated with the operation of the retinal prosthesis, b) determi...

a simple new closed form of the green function for axisymmetric magnetostatic problemsis found analytically in cylindrical coordinates. the result is verified by applying several examples.

We consider symmetric preconditioning strategies for the iterative solution of dense complex symmetric non-Hermitian systems arising in computational electromagnetics. In particular we report on the numerical behaviour of the classical Incomplete Cholesky factorization as well as some of its recent variants and consider also well known factorized approximate inverses. We illustrate the difficul...

Model order reduction (MOR) methods are more and more applied on many different fields of physics in order to reduce the number of unknowns and thus the computational time of large-scale systems. However, their application is quite recent in the field of computational electromagnetics. In the case of electrical machine, the numerical model has to take into account the nonlinear behaviour of fer...

We consider preconditioning strategies for the iterative solution of dense complex symmetric nonHermitian systems arising in computational electromagnetics. We consider in particular sparse approximate inverse preconditioners that use a static nonzero pattern selection. The novelty of our approach comes from using a di erent nonzero pattern selection for the original matrix from that for the pr...

This paper deals with an efficient and fast approach for determining the mutual inductance between coaxial circular coils of rectangular cross section in combination with thin coaxial circular coils as the thin wall solenoid, the thin disk coil and the filamentary coil. This approach is based on the filament method where conductors are approximated by the set of Maxwell’s coils. The obtained ex...
