In practical engineering applications, factors like dust adhesion and environmental changes can cause photovoltaic arrays to exhibit multiple peaks in output power. An optimization algorithm with global capability is needed track its maximum this regard, paper proposes an improved marine predator (IMPA) extract the power point of system under complex solar irradiation conditions. To overcome issues traditional (MPA), opposition-based learning(OBL) strategy introduced IMPA, sine cosine (SCA)...
Using a prior data to solve for the characteristic parameters of moving magnetic target is crucial in its detection. For this purpose, we developed real-time detection method using distributed scalar sensor networks based on hybrid algorithm combining particle swarm optimization and Gauss-Newton method. The anomaly fitting model established magnetic-dipole-moment principle. PSO’s insensitivity initial solution used obtain rough coefficients fitting, then more accurate method, exploiting...

Infrasound, i.e., low-frequency noise in the frequency range of 10–200 Hz, produced by rotating wind turbine blades has become a matter concern because it is harmful to human health. Today, with rapid increase size, this kind more worrying than ever. Although much effort been made design quiet blades, today there still lack effective techniques reduce infrasound emissions from existing blades. To fill gap technology, biomimetic technique that can be readily applied studied paper using both...
With the development and application of a bionic flapping micro aircraft vehicle (FMAV), further requirements for its high maneuvering flight characteristics have been put forward. A controlling tail cannot meet insect-sized FMAVs, it has become necessary to find new mechanisms flight.
