Free Monadic Tarski and MMI3-Algebras
MMI3-algebras are a generalization of the monadic Tarski algebras as defined by A. Monteiro and L. Iturrioz, and a particular case of the MMIn+1-algebras defined by A. Figallo.

Third Order Melnikov Functions of a Cubic Center under Cubic Perturbations
In this paper, cubic perturbations of the integral system (1+x)2dH where H=(x2+y2)/2 are considered. Some useful formulae are deduced that can be used to compute the first three Melnikov functions associated with the perturbed system.

Weaknesses in ENT Battery Design
Randomness testing is a key tool to analyse the quality of true (physical) random and pseudo-random number generators. There is a wide variety of tests that are designed for this purpose, i.e., to analyse the goodness of the sequences used.

Detection of Demagnetization Faults in Axial Flux Permanent-Magnet Synchronous Wind Generators
A new method for detecting demagnetization faults in axial flux permanent magnet synchronous wind generators is presented in this study. Demagnetization faults occur in the case of total or partial loss of the magnetic properties of one or more permanent

Accurate Modeling of a Transverse Flux Permanent Magnet Generator Using 3D Finite Element Analysis
This paper presents an accurate modeling method that is applied to a single-sided outer-rotor transverse flux permanent magnet generator. The inductances and the induced electromotive force for a typical generator are calculated using the magnetostatic

Determination of the impurities concentration in tungsten, molybdenum, tin, and tellurium targets using neutron activation analysis techniques [PDF]
The fast and k0-neutron activation analysis (k0-NAA)methods were used to investigate the radioimpurities concentration of 124Sb, 134Cs, 60Co, 87Rb, 182Ta, 233Pa, 65Zn, 56Fe, 110mAg, 51Cr, 95Zr, 75Se and 114mIn in the target samples WO3, MoO3, SnO2 and ...
