Bifurcations in a second-order difference equation from macroeconomics†Supported by NSFC, TRAPOYT and MOE Research grants.

open access: closedJournal of Difference Equations and Applications, 2007
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 ...

Convergence to equilibria and blowup behavior of global strong solutions to the Stokes approximation equations for two-dimensional compressible flows with large data☆☆Partially supported by the National Natural Science Foundation of China under contracts 10471138, 10601059, and 10526039 (Tianyuan Jijin); NSFC–NSAF Grant No. 10676037; 973 project of China, Grant No. 2006CB805902; Zheng Ge Ru Funds, Grants from RGC of HKSAR CUHK4028/04P and CUHK4299/02P.

open access: closedJournal de Mathématiques Pures et Appliquées, 2006
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 ...

Who are the international research collaboration partners for China? A novel data perspective based on NSFC grants

open access: closedScientometrics, 2018
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.

Robust Fault Estimation for Vehicle Lateral Dynamic Systems11Partially supported by the NSFC Grant (60574026) and the Alexander von Humboldt Foundation (1117303)

open access: closedIFAC Proceedings Volumes, 2007
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, 2005
Timing 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.
