Scaled experimentation is an important experimental approach but known to be limited by scale effects, which have the undesirable effect of changing behaviour a system with scale. Such behavioural changes can on occasions so marked as make scaled experiment almost worthless. Until very recently, there has been no universal solution this problem most experiments founded dimensional analysis and ...

In this paper, we propose a species-based hybrid of electromagnetism-like mechanism and back-propagation algorithms (SEMBP) for an interval type-2 fuzzy neural system with asymmetric membership functions (aIT2FNS). The proposed SEMBP combines the advantages of EM and BP algorithms to obtain the faster convergence and lower computational complexity. In addition, SEMBP uses the uniform method to ...

In this paper, we propose a hybridization of electromagnetism-like mechanism (EM) and particle swarm optimization algorithm (PSO) algorithms to design the proposed functional-link based Petri recurrent fuzzy neural system (FLPRFNS) for application of nonlinear system control. The FLPRFNS has a TSK-type fuzzy consequent part which uses functional-link based orthogonal basis functions and a Petri...

In introductory level electromagnetism courses the calculation of electrostatic potential and electric field in an arbitrary point is a very common exercise. One most viewed cases symmetry axis centered ring it has been widely studied off charged origin coordinate. this work, we calculated $z$ non using elliptic integrals as pedagogical example application special functions electromagnetism.

We discuss the seminal article in which Le Bellac and Lévy-Leblond have identified two Galilean limits of electromagnetism [1], and its modern implications. We use their results to point out some confusion in the literature and in the teaching of special relativity and electromagnetism. For instance, it is not widely recognized that there exist two well defined non-relativistic limits, so that ...

In this paper, we study the limitations imposed by the laws of electromagnetism on achievable MIMO channel capacity in its general form. Our approach is a three-fold one. First, we use the channel correlation argument to demonstrate that the minimum antenna spacing under any scattering conditions is at least half a wavelength. Secondly, using a planewave spectrum expansion of a generic electrom...

Electromagnetism is usually understood as a theory describing how charged particles and eletromagnetic elds interact. In this paper I argue that a double ontology comprising both particles and elds is problematic. Either we should think of electromagnetism as a theory about charged particles directly interacting with each other, or as theory of elds whose local interactions are manifested as...

Aim at the class electromagnetic algorithm (EM) late for “mining” ability is insufficient, solution precision is not higher, and easy in premature problem, this paper proposes a combination of chaotic map and confined quasi-Newton (L-BFGS) local optimization operator of the chaotic class electromagnetism algorithm. Its main idea is in the late class electromagnetism algorithm using limit domain...
