Air pollution caused by particulate matter with aerodynamic diameters less than 2.5 μm (PM2.5) is a serious environmental problem. Plants can improve air quality by removing PM2.5 from the atmosphere. However, direct evidence of PM2.5 absorption and assimilation into plants has not yet been found. In this study, we demonstrate that 15NH4+ in PM2.5 was absorbed by poplar leaves in low and high PM2.5...
In order to further improve the efficiency and reliability of current path planning algorithms applied to embedded vehicle navigation systems, a novel path planning algorithm is proposed in this paper based on a concise topology electronic map. In the proposed algorithm, the traditional searching area is optimized by tackling the path planning problem in a capsule-like restricted area. Furthermore,...
The intelligent vehicle steering control is an important part of Intelligent Vehicle System. This article explores the kinematical model of vehicle and the driver's behavior for the issue of the vehicle steering, and it proposes an expertise-based fuzzy control method that is built on a foundation of the visual image processing technology. This article also deeply analyzes the parameters of the control...
In the processing of video image data, the data need to be stored and transferred to other functional units in or out of the system in real time. Especially in a complex system, it needs a special platform to store and transfer video image data in real time. This article presents a design of video image's storage converter based on FPGA. This storage converter can convert the video image data format...
