SUMMARYA method for decomposition of uni"ed (continuous/discrete) linear quadratic regulator with two-time-scale property is presented. The composite and the reduced-order controls are formulated in standard uni"ed domain. By appropriate transformations, it is shown that the results of continuous-time (CT) and discretetime (DT) obtained previously using two separate techniques, can be obtained by this single uni"ed technique. With this method, there is no need to consider two-time scale systems in continuous and the discrete domains separately. This paper also presents some numerical examples to illustrate the theoretical results.

As immigrant fiction continues to emerge from the South

The purpose of this review is firstly to show the formation of dystopia that finds its roots in utopia. Then, the foundation of dystopian fiction from the perspectives of such critics as Chad Walsh, Tom Moylan, Mark R. Hillegas, and Erika Gottlieb, among some others, is investigated. Finally, we briefly reveal the standing of Aldous Huxley, Kurt Vonnegut, and Don DeLillo, among many other dystopian writers, in depiction of dystopian societies. This study also attempts to explain how works of these three writers were revolutionary in their challenging of the new values that led to the degradation of human dignity.
