Experimental analysis of harmonic distortions in the excitation currents of double-excited three-phase transformers

This paper shows the results of experimental investigations of three-phase banks composed of single-phase transformers and three-phase three-limb core transformers under simultaneous alternating and direct current excitations, for several winding connections. Harmonic analysis of excitation currents for different de saturation levels is performed.

double-struck D signn-forced symmetry breaking of double-struck O sign (2)-equivariant problems

We use singularity theory to classify forced symmetry-breaking bifurcation problems f(z, λ, μ) = f1 (z, λ) + μf2(z, λ, μ) = 0, where f1 is double-struck O sign (2)-equivariant and f2 is double-struck D sign n-equivariant with the orthogonal group actions on z ∈ ℝ2. Forced symmetry breaking occurs when the symmetry of the equation changes when parameters are varied. We explicitly apply our results to the branching of subharmonic solutions in a model periodic perturbation of an autonomous equation and sketch further applications.

Les enquêtes militaires et l-organisation des intellectuels de gauche au Brésil dans les années 1960

This article has as its object of analysis the Inquiries Police-Military, adocumentation produced during the military dictatorship in Brazil (1964-1985)and today it’s important sources for historians, sociologists, political scientists to understand the internal dynamics of repression, as well as specifying certainnetworks communist militancy and the engagement of progressive sectorsagainst the military government. Documents, court proceedings that currently in Brazil endorse the work of the Truth Commission, which seeks to ascertain the fate of disappeared politicians and determine the actions of the organs of repression during the military dictatorship in Brazil.

O paradigmático caso do processo às juntas militares argentinas

This article analyzes the case of the proceedings against Argentina’s Military Juntas that led to jail those responsible for heinous crimes committed during the military dictatorship. The said proceeding has a high symbolic value in the struggle for human rights in Latin America and is relevant and timely in Brazil where the right to the truth regarding the missing people during the military dictatorship is in debate, as well as the invalidation of the Amnesty Act regarding the common crimes of torture, rape and / or kidnapping, among others. In the case of Argentina, following Roxin’s doctrine of mediate authorship, the Court held that the crimes were committed by the military through the use of an organized power apparatus and emphatically dismissed allegations that such crimes were justified in the so-called “dirty war”. Thus, the case against the Military Juntas has become a paradigmatic one, not only in Argentina, where many military leaders had to respond to criminal actions, but for all countries in the region that faced similar situations in recent history.

Negative Even Grade mKdV Hierarchy and its Soliton Solutions

In this paper we discuss the algebraic construction of the mKdV hierarchy in terms of an affine Lie algebra (s) over capl(2). An interesting novelty araises from the negative even grade sector of the affine algebra leading to nonlinear integro-differential equations admiting non-trivial vacuum configuration. These solitons solutions are constructed systematically from generalization of the dressing method based on non zero vacua. The sub-hierarchies admiting such class of solutions are classified.

Methodology for load compensation in four-wire electrical power systems based on instantaneous sampling

This work describes a methodology for power factor control and correction of the unbalanced currents in four-wire electric circuits. The methodology is based on the insertion of two compensation networks, one wye-grounded neutral and other in delta, in parallel to the load. The mathematical development has been proposed in previous work [3]. In this paper, however, the determination of the compensation susceptances is based on the instantaneous values of load currents. The results are obtained using the MatLab-Simulink enviroment

A note on non-degenerate umbilics and the path formulation for bifurcation problems

Path formulation can be used to classify and structure efficiently multiparameter bifurcation problems around fundamental singularities: the cores. The non-degenerate umbilic singularities are the generic cores for four situations in corank 2: the general or gradient problems and the ℤ 2-equivariant (general or gradient) problems. Those categories determine an interesting 'Russian doll' type of structure in the universal unfoldings of the umbilic singularities. One advantage of our approach is that we can handle one, two or more parameters using the same framework (even considering some special parameter structure, for instance, some internal hierarchy). We classify the generic bifurcations that occur in those cases with one or two parameters.
