As it is the ＂presence＂ of ＂absence＂, the charm of Utopia lies in that it is not only distant otherness, but a kind of existence always touching the undercurrent of reality. In contemporary era, Utopia exists in the paradoxical form of dystopia. It is just in the review on Utopia that the political potential of art enables aesthetic Utopia re-enter its promising holy land as a new configuration of contemporary Utopia. However, the practice of aesthetic Utopia is not entirely poetic; on the contrary, there are always many fields which intertwine around and fight against each other between reality and expectations. Therefore, the aesthetic revolution chooses a more prudent way after the passionate release.展开更多

Utopia and eschatology will be accepted as a manner of harmonizing two dialogical reflexes sent as well from the discussion proposed by the journal Communio： International Catholic Review as from the perspective of the operational-utopian concepts, filtered by the Transylvanian magazine Utopia in the 1930s. The magazine recovered after 48 years a coincidence of cultural-political-religious-technical order, which drew to a declared philosophical attitude. The study will verify the working hypothesis, according to which utopia is self-proclaimed, in religious register, type-program-solution and concept-belief-philosophy.展开更多

The conventional optimization method is generally based on a hierarchical structure in which the upper optimization layer calculates the steady-state results and the lower control layer is responsible to drive the process to the target point. However, the conventional hierarchical structure does not take the economic performance of the dynamic tracking process into account. To this end, multi-objective economic model predictive control(MOEMPC) is introduced in this paper, which unifies the optimization and control layers in a single stage. The objective functions are formulated in terms of a dynamic horizon and to balance the stability and economic performance. In the MOEMPC scheme, economic performance and SO_(2) emission performance are guaranteed by tracking a set of utopia points during dynamic transitions. The terminal penalty function and stabilizing constraint conditions are designed to ensure the stability of the system. Finally, an optimized control method for the stable operation of the complex desulfurization system has been established. Simulation results demonstrate that MOEMPC is superior over another control strategy in terms of economic performance and emission reduction, especially when the desulphurization system suffers from frequent flue gas disturbances.展开更多

Categorization of two candidate areas is carried out using the water-energy dynamic (for Ecuador, South America) and Macedonia, Southern Europe), within which the life-form spectra are distributed. Genetic optimization methods are used to expand the primary nodal number to the complete number of life-form categories. The distribution of the elements exhibits a stochastic, binomial distribution and the utopia line and curve are summarized which enhance accuracy of the climatic data and of the consequent numbers of plant species occurrences. Expansion of the distribution of each life-form category is approximated within the Z utopia hyperplane with use of the functional approximation algorithm. This process gives additional structure and informative value to the Z plane, enhancing our ability to make informed policy decisions concerning species and ecosystem conservation.展开更多
