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.

A estética japonesa na cultura brasileira: reflexões a partir de um estudo etnofotográfico sobre a performance ritual da festa da Cerejeira de Garça-SP

Aiming to understand the Japanese aesthetic in Brazilian culture and to produce a photographic exhibition of artistic and ethnographic nature, we performed a symbolic exegesis of the ritual performance of Garça Cherry Festival - SP (Brazil). The event takes place annually and is held in memory and honor of oriental culture. The festival features various elements of Japanese culture through expressive forms such as dance, music, costumes, martial arts and cooking. Therefore, the study was based on the anthropology of performance and visual anthropology with regard to symbolic exegesis of the party and look artistic and ethnographic photographic records of the proceedings. Such procedures supported the realization of artistic display that contributed, in turn, in promoting the local culture to a wider audience, and, methodologically, have contributed in visual identification and interpretation of the cultural elements of the ceremony.
