Currently most of UAV navigation systems are composed of GPS/INS integrated navigation. To give a alternative navigation method when GPS doesn't work on UAV, a machine vision-aided navigation method is proposed to navigate the UAV with INS. Image Stitching as the core technology is to build real-time ground panoramic image. Combined with GPS latitude and longitude information, certain data fusion...
A study was conducted on the adsorption kinetics of diuron from aqueous solutions onto activated carbon fiber. The results showed that the formation of hydrogen bonds between diuron and water, and temperature variations may possibly affect the adsorption process. Furthermore, adsorption of diuron onto activated carbon fiber was affected remarkably by solution pH and the maximum adsorption amount was...
In this letter, a new kind of cavity resonator based on left-handed/right-handed transmission lines is presented. The left-handed transmission line (LHTL), which can realize a negative phase shift, is formed by resonant-slot coupled cavity chain unit cells, while the right-handed transmission line (RHTL), which can realize positive phase shift, is made of coaxial waveguides. Resonance condition can...
