In this note we explore the possible marginal deformations of general (0,2) non-linear sigma-models, which arise as descriptions of the weakly coupled (large radius) limits of four-dimensional N = 1 compactifications of ...

With the growth of customer demand level, at last two decades it appeared quality improvement approach focusing customer satisfaction as the way to the organizations improve the efficiency and effectiveness of their ...

Using Sigma theory we show that for large classes of groups G there is a subgroup H of finite index in Aut(G) such that for phi is an element of H the Reidemeister number R(phi) is infinite. This includes all finitely ...

Este artigo apresenta o modelo de referência para estruturar o Seis Sigma, o qual é resultante da incorporação de teorias que contribuem para aumentar o potencial estratégico do Seis Sigma no sentido de incrementar o ...

We construct recursively an infinite number of Poisson structures for the supersymmetric integrable hierarchy governing the Pohlmeyer reduction of superstring sigma models on the target spaces AdS(n) x S(n), n = 2, 3, 5. ...

The purpose of this paper is to systematise principles and practices of the Lean Six Sigma (LSS) method to encourage and facilitate its implementation and management in different contexts. The construction of LSS principles ...

The implementation of Lean Six Sigma in the public sector has grown considerably in recent years and may be accentuated in times of global economic crisis. Even so, general aspects that can guide managers for its implementation ...
