In response to accounting scandals, market control systems (e.g. regulations related to internal control systems) have become more stringent in order to restore investors’ confidence in capital markets. Tightening control systems has triggered a fierce debate on its effect on both capital markets and the real economy. My dissertation studies how mitigating earnings management by tightening cont...

A feedback-based congestion control mechanism is essential to realize an efficient best-effort service in high-speed networks. A window-based flow control mechanism called TCP (Transmission Control Protocol), which is a sort of feedback-based congestion control mechanism, has been widely used in the current Internet. Recently proposed TCP Vegas is another version of TCP mechanism, and can achie...

A new prescribed-time state-feedback design is presented for stochastic nonlinear strict-feedback systems. Different from the existing where scaling-free quartic Lyapunov functions or scaled quadratic are used, based on functions. The designed controller can ensure that plant has an almost surely unique strong solution and equilibrium at origin of mean-square stable. After that, authors redesig...
