This paper addresses a surgeries scheduling problem with a single server in charge of key medical facility. A surgery can be processed with a precedent setup by the server on one of available operating rooms. The setup can be processed at only one surgery at any time. Thus, it is critically important to simultaneously consider the setup precedence and operating room scheduling decisions. A robust...
Digital watermarking is a technique used to embed an extra piece of information into multimedia signals. Aiming at content-based audio retrieval applications, a robust audio watermarking scheme resist to low bits rates compression is proposed. The performance of proposed algorithm is analysis by common signal processing such as Mp3 compression, Real compression, filtering, amplitude compression, equalization,...
This paper deals with the reliable control for uncertain singular systems with time-varying delay. Based on integral inequality, an linear matrix inequality (LMI) approach is developed to design desired state feedback controllers, such that the closed-loop system is regular, impulse free and stable for all admissible actuator failures. All the obtained results are formulated by strict LMI involving...
The problem of delay-dependent robust stabilization for uncertain system with time-delay is considered. A Lyapunov-Krasovskii functional is designed by splitting the whole time-delay interval into some subintervals and defining different energy functions in every subinterval. Combining with linear matrix inequalities (LMI) technique, a delay-dependent stability criterion is derived in terms of LMI...
This paper presents a novel energy-based watermarking scheme (EBW). The aim of EBW is to make the watermark survive video compression and collusion. After carefully analyzing the effect of the video compression on different type regions of video, two properties of the video coding are explored. According to these two properties, the watermark is deliberately embedded into the video to improve the...
Poincare-like-alter-cell-to-cell mapping method is proposed to search for the tracking target point, when the slope of the ground or the structure parameters of the underactuated biped robots have changed. The finite-time robust trajectory tracking control strategy is designed to make the states of the system reach the tracking target point in finite time. This control strategy is based on the theory...
