Currently, positron emission tomography/computed tomography (PET/CT)‐based Ann Arbor and Lugano staging systems are widely applied for gastric lymphoma, which majorly focused on the extent of systemic invasion, but there is insufficient assessment in extent of gastric wall invasion. Thus, we aimed to assess the value of linear‐array EUS in therapeutic response and prognosis prediction,...
This paper focus on classification of coastal landform. The study area is locate in QinZhou, Guangxi Zhuang Autonomous Region, China, using GF-1 image. In view of complex coastal landform, the current study firstly transforming RGB model to CIE LAB model, dividing image based on colour gradient, then conducting Gabor filtering and PCA transformation to develop texons and generating texton histogram...
Current regulator designing is the key step in high performance PWM rectifier controller designing. When switching frequency is about hundreds of hertz, conventional Bode diagram design method is not suitable. With the help of the discrete-time model of the current control loop and the bilinear transformation, the model can be transformed to a suitable form, and Bode diagram method can be used again...
Synthetic Aperture Radar (SAR) satellite image is first used to monitor dramatically growing green algae near Qingdao coastal in 2008. The system played important role in ensuring Qingdao 2008 Olympic Sailing Competition. Based on imagery statistic analysis, the influences of radar parameter on detection performance are evaluated. A processing method which used in practice is presented. Processing...
The threat imposed on the safety of EUT (Equipment Under Test) supply in power leads conducted susceptibility test covered by MIL-STD-461/462 was investigated by using sinusoidal steady state linear circuit phasor. With the impact of testers output impedance characteristic analyzed, the solution that is phase compensation is presented and its effect and feasibility are verified.
Control allocation problem is the key of cooperation control systems and has attracted a lot of attention of researchers. This paper proposes a nonlinear control allocation framework to provide a common optimal solution for decentralized cooperation control systems. The framework includes the allocation controller and feedback control law. In which, the allocation controller is designed to realize...
A new efficiency-optimized strategy of LIM (Linear Induction Motor) for Linear Metro is proposed in this paper. First, a dynamic mathematical model of LIM is derived based on analyzing the end effect. Then a field orientation control scheme with the actual parameters is developed. Based on the mathematical model of LIM, optimal flux control based on model is raised so as to deal with the problem of...
