In this paper, we extend the sliding mode idea to a class of unmatched uncertain variable structure systems. This method is achieved with introducing a new terminal sliding variable and the finite time stability of proposed method is proved using a new particular finite time condition in both reaching and sliding phases. In reaching phase new sliding mode controller is derived to guarantee the ...

— The complexity ofa X-term is defined as the number of ^-réductions needed to reach its normal form («.ƒ.). In the present paper some gênerai properties of the complexity of applications of n. ƒ s. are stated and this complexity is maximized, in some interesting cases, as a function of parameters describing the structures of the current n.f. s.

With the rise of the Asian financial crisis in 1997 and the smash of IT bubbles in 2000, there has been an increase in the number of corporate takeovers and mergers. In light of these events, we investigate the effects of acquisition announcements on the pricing behavior of the Asian bidding and target firms using the data of mergers or acquisitions announcements from the Bloomberg Database and...
