In this paper, the dynamics of a flapping wing vehicle are studied. A quasi-steady model is developed to analyze its aerodynamic forces and moments. The unsteady effects are considered both in hovering state and forward flight state. Different from existing flapping wing vehicle dynamics model, the rudder's dynamics are concurrently considered in the proposed one. Numerical simulation is conducted...
Software that applied in the industrial safety-critical systems are usually developed from reused components. The redundant parts of the safety-critical software introduced by such approach shall therefore be considered from the perspective of avoidance and protection from systematic failure. The large scale and high complexity of modern safety-critical software increase the difficulty on conducting...
In this paper, the support vector machine (SVM) optimized by the improved fruit fly algorithm and the similar day method is employed in the short-term load forecasting. In practice, the learning capacity and generalization ability of SVM are controlled by the regularization parameters, parameters of the kernel function and insensitivity loss functions, which were confirmed based on the experience...
As urban distribution activities becoming frequently, the urban distribution enterprise has accumulated a mass of distribution case knowledge service. How to quickly identify and agilely reuse these massive distribution knowledge, to support the urban distribution activities well, has become a focus of reach of scholars. Based on defining the concept of urban distribution tasks context and case context,...
This paper proposes a simplified model to describe distance node interference in IEEE802.11 based Wireless Mesh Network (WMN). An Interference Range based Rate Control (IRRC) scheme to resist interference from distant terminals based on interference level adjustment is presented, which builds tradeoff between custom FER and transmission rate according to current estimated interference level. Simulation...
