In this paper we discuss a second-order difference equation which was modeled from macroeconomics. Continuing Sedaghat's results on permanence, boundedness, oscillation and asymptotic stability, we discuss its flip bifurcation and Neimark–Sacker bifurcation by investigating its equivalent planar mapping and calculating its center manifold and normal ...

AbstractThis paper concerns the large time behavior of strong and classical solutions to the two-dimensional Stokes approximation equations for the compressible flows. We consider the unique global strong solution or classical solution to the two-dimensional Stokes approximation equations for the compressible flows with large external potential force ...

International research collaboration is vital to the success of scientific development of China, and the identification of collaboration partners is the basic unit of collaboration. While many researchers have investigated international research collaboration using publication data, grant data have rarely been used.

Abstract For systems with unknown input disturbances, a robust state-space observer is designed to simultaneously estimate the system state, the finitely times derivatives of the fault, and the fault signal at the same time. The considered fault signal can be allowed to be unbounded provided its finitely times derivative is bounded.

Timing-Driven Global Routing with Efficient Buffer Insertion
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2005Timing optimization is an important goal of global routing in deep submicron era. To guarantee the timing performance of the circuit, merely adopting topology optimization becomes inadequate. In this paper, we present an efficient timing-driven global routing algorithm with buffer insertion.
