The optimal foraging algorithm (OFA) was proposed by summarizing the rules of the animal foraging behavior in a group.Therefore OFA also has the defects of the swarm intelligence algorithm, such as easy to trap into local optimum and low convergence accuracy.In order to Resines UV overcome these defects, an optimal foraging algorithm based on diffe
Introduction: Injuries combining a humeral head fracture-dislocation and a shaft fracture of the ipsilateral humerus are very rare.They should be separated from extended fractures of the humeral head to the shaft [1].Case report: We present the case of an active 84-year-old man who sustained a three-part fracture-dislocation of the proximal humerus
This paper mainly discusses about the full-order state observation technology for the permanent magnet synchronous motor (PMSM) drive system.First, the concept of the Kalman filter (KF) is synthesized to design a novel fixed gain filter (FGF) with an optimal fixed feedback gain Camcorder matrix, which ensures a fast and accurate observation for pos
Global navigation satellite systems (GNSSs) provide accurate positioning and timing services in a large gamut of sectors, including financial institutions, Industry 4.0, and Internet of things (IoT).Any industrial system involving multiple devices interacting and/or coordinating their functionalities needs accurate, dependable, and trustworthy time
