<p>Computer simulations are a powerful tool to support the design and development of electrical components and equipment. However, simulations are configured by a user, thus inevitably incorporating the human factor and potentially leading to divergence in results. To assess this degree of variance and thus the role of the user, 10 participants were asked to simulate the same medium voltage porcelain pin insulator using FEM software. Boundary conditions and materials were fixed. However, participants were able to define the geometry and details of the pin insulator by any means at their disposal. The varying skills of the participants resulted in geometries ranging from highly detailed complex models to rougher approximations. A CAD model provided by the pin insulator manufacturer is used as a reference. To quantify the extent of divergence, electric field intensity values in selected critical areas of the geometry are compared. This study presents the influence of the human factor and investigates the requirements for reliable simulation, i.e., how detailed does a model have to be to produce reliable information. The findings of this study can be used to save time and focus efforts on pertinent aspects in simulations.</p>

The dynamics with an infrared stable fixed point in the conformal window in QCD like theories with a relatively large number of fermion flavors is reviewed. The emphasis is on the description of a clear signature for the conformal window, which in particular can be useful for lattice computer simulations of these gauge theories.

Joint Method

A new joint method is presented to estimate the 2-D DOA and polarization parameters of far-field sources based on four order cumulant. The method adopts L array, and every sensor consists of orthogonal dipole-pairs with the same coordinate axis direction, which measure the x-axis and y-axis electric-field components of the far-field signals. The method constructs four four-order cumulant matrixes by receiving polarized array data and does not require any spectral peak search and parameter pairing, can be applied to additive Gaussian white noise or color noise environment. The performance of the proposed method is verified by computer simulations.

Monodisperse System

In colloids with competing interactions, an electric field-induced column-like structure relaxes back to the microcrystalline gel spontaneously as the field is switched off. Computer simulations show that even a very small polydispersity destabilizes ordered periodic structures that would have been stable in a monodisperse system.
