文摘Starting from the observation of a greater religious pluralism of the Brazilian society, we ask ourselves, in the f＇trst instance, if it is a movement does not present itself as a paradigmatic change. That is, if as beliefs underlying social relations in a binary world of identity exclusions would not be in a process of weakening, allowing us to perceive new ways of latent arrangements. In a second instance, after recognizing that plurality requires recognition of the freedoms of belief and expression, we question the limits of such freedom point to a cosmopolitan ethics. For that matter, we take as reference in the non-religions in the Brazilian urban peripheries.

文摘This paper proposes a decoupling control scheme with two-degrees-of-freedom (2DOF) control structure. In the proposed scheme, two multivariable controllers are designed based on Internal Model Control (IMC) theory for setpoint tracking and disturbance rejection independently. An analytical approximation method is utilized to reduce the order of the controllers. By adjusting the corresponding controller parameter, the setpoint tracking and disturbance rejection of each control loop can be tuned independently. In the presence of multiplicative input uncertainty, a calculation method is also proposed to derive the low bounds of the control parameters in order to guarantee the robust stability of the system. Simulations are illustrated to demonstrate the validity of the proposed control scheme.
