A Bayesian inference based Markov regime switching model is introduced to predict the intraday solar radiance. The proposed model utilizes a regime switching process to describe the evolution of the solar radiance time series. The optimal number of regimes and regime-specific parameters are determined by the Bayesian inference. The Markov regime switching model provides both the point and interval...
Simulink Stateflow is widely used for the model-driven development of software. However, the increasing demand of rigorous verification for safety critical applications brings new challenge to the Simulink Stateflow because of the lack of formal semantics. In this paper, we present STU, a self-contained toolkit to bridge the Simulink Stateflow and a well-defined rigorous verification. The tool translates...
We present a novel selector made of doped-chalcogenide material. This selector not only achieves low holding voltage (0.2 V) and large on/off ratio (>107), but also exhibits the high on-current density (>1.6 MA/cm2) and large hysteresis window (1.2 V). Besides, excellent selector performances with ultra-low off-state leakage current (10 pA), high switching speed (<10 ns), high endurance (>10...
In this paper we investigate the attitude control problems of underactuated spacecraft by moving masses. First, the attitude dynamics and kinematics equations of underactuated spacecrafts with two moving masses are given. Then, considering the stabilization of the roll and pitch attitude, We present a controller designed using a linear Lipschtiz surface combined with the traditional sliding model...
An algorithm for fast constructing Delaunay triangulations was proposed. In iterations, this algorithm is to select the leftmost one point lying right some convex edges from set of points. The point and those convex edges construct new triangles, and add them to Delaunay triangulations. At same time, when new triangles do not meet Deaunay condition, optimize triangles based on LOP method, which is...
