Long term trajectory prediction of a flying vehicle is to estimate the position in the upcoming task procedure. For extratmosphere vehicles that have the ability to track and pursue other vehicles, due to its autonomous maneuver and high mobility, long term trajectory prediction is very difficult. In this paper, a trajectory prediction method for pursuing vehicles based on advanced guidance law recognition...
In order to achieve the energy management of DC micro-grid, a multi-agent control method is proposed in this paper. The designed intelligent agent system has two layers. The lower layer agent is composed of photovoltaic power agent, wind power agent, energy storage agent and load agent. Those lower agents collect the data from field devices, and each agent analyzes the data, then the information from...
Road recognition is critical for safe driving and intelligent vehicles. In order to improve the real-time and stability of lane recognition, a robust road recognition algorithm based on improved Canny and Progressive Probabilistic Hough Transform (PPHT) is proposed in this paper, Experiments prove accuracy of the lane recognition and high real-time capability in the different scenarios.
Helix is widely used in industrial modeling. Characteristic parameterization and modeling are based on helix parameterization. However, helix cannot be accurately represented by NURBS, and no helix interface for UG secondary development. It is difficult for modeling parameterization based on helix. This paper proposed a novel modeling method by using NURBS approximating helix, and presented the error...
The 2010 Yushu earthquake caused tremendous life and economic loss in Yushu county, Qinghai, China. More than hundred thousand buildings were totally or partially collapsed. This paper focuses on the 3D visualization of disaster environment in both coarse scale and fine scale for further disaster management. In the study area, different data resources were used in different scales for different purpose...
We used the micro-Raman spectroscopy to investigate the V-grooved quantum well wires (QWWs), and first observed and assigned the Raman spectra of single QWW. They were the disorder induced modes at 223 and 243 cm−1, confined LO mode of GaAs QWW at 267 cm−1, and higher order peaks of disorder induced modes at 488 and 707 cm−1.
