Dynamics analysis and simulation of six DOF parafoil systemSpringer Science and Business Media LLC - Tập 22 - Trang 12669-12680 - 2018
Zhixiang Zhang, Zining Zhao, Yongling Fu
An increasing demand for the flight dynamics identification in studying parafoil system arises. In this paper, we explore the natural motion principle to investigate the parafoil flying based on structure configuration. A six degree of freedom parafoil model is established via aerodynamic equations. Consequently, simulations on the airdropping procedure is conducted. Given that the simulation outc...... hiện toàn bộ
A novel sparrow search algorithm with integrates spawning strategySpringer Science and Business Media LLC - - Trang 1-21 - 2023
Jiaxiang Zhang, Linwei Li, Huanlong Zhang, Fengxian Wang, Yangyang Tian
Sparrow Search Algorithm (SSA) has recently received more attention in the intelligent optimization group. However, the high randomness and local optimal problems of the algorithm limit the application of the algorithm. In this paper, a novel sparrow search algorithm (NSSA) combined with spawning technology is proposed, which effectively improves the problem of the algorithm falling into local opt...... hiện toàn bộ
Design of hierarchical coordination model for ubiquitous applicationSpringer Science and Business Media LLC - Tập 15 - Trang 69-77 - 2011
Seungkeun Lee, Daesung Lee, Donghwi Lee
Our research targets collaborative environments with focus on mobility and teams. This environment comprise a number of people working on multiple tasks and activities simultaneously. As mobile and wireless technology advances people are no longer bound to their offices. Team members are able to collaborate while on the move. So, mobile ubiquitous application can be a best solution to provide a mo...... hiện toàn bộ
