the caspian sea region, because of the proximity of two permanent powers - russia and iran- and the emergence of newly independent republics, is one of the most dynamic places in the world. in addition, the continuity of interests of other global actors, including the united states and europe, with the coastal countries has added to the complexity and dynamics. in this regard, the region energy...

In this paper, we consider the problem of finding the stability region in state space for uncertain linear systems with input saturation. For stability analysis, two Lyapunov functions are chosen. One is for the linear region and the other is for the saturated region. Piecewise Lyapunov functions are obtained by solving successive linear matrix inequalities(LMIs) relaxations. A sufficient condi...

Motivated by recent developments in ion trap design and fabrication, we investigate the stability of ion motion in asymmetrical, planar versions of the classic Paul trap. The equations of motion of an ion in such a trap are generally coupled due to a nonzero relative angle θ between the principal axes of RF and DC fields, invalidating the assumptions behind the standard stability analysis for s...

We investigate the composite effects of multipacket reception (MPR) and relaying capability in affecting the stability region of a wireless network. With a general MPR channel, a trade-off arises as to whether to activate the relay simultaneously with the source so that both transmissions might be successful, or to let the relay remain silent to overhear the source’s transmission and then activ...

The ability of pulmonary surfactant to reduce alveolar surface tension requires adequate expression of surfactant protein B (SP-B). Dexamethasone (DEX, 10(-7) M) increases human SP-B mRNA stability by a mechanism that requires a 126-nt-long segment (the 7.6S region) of the 3'-untranslated region (3'-UTR). The objective of this study was to identify sequences in the 7.6S region that mediate regu...

A classi cation in terms of accuracy of ux limited high resolution schemes in steep gradient region is done based on two di erent total variation (TV) stability region. The dependence of TV stability region on the smoothness parameter is discussed which relates these two TV stability regions. A common unifying TV stability region is proposed for both class of schemes. Moreover new ux limiters, ...

The stability and the stability region of a (controlled) industrial system is an important property to be determined. It is highly desirable to have a system that is not able to become unstable that is why the stability theory is being continuously in both the theoretical researchers’s and industrial partitioner’s focus. The aim of this paper is to examine the stability region of an existing in...
