GA airport bird-scaring equipment effectiveness assessment is an important part in the process of dealing with bird hazard. This paper establishes the scientific and systematic evaluation index system and designs the assessment model by means of fuzzy mathematics method. Verification by a domestic GA airport showed that the result of risk assessment from this model and the system were basically consistent...
It is important to understand how wildland fire is spreading in a given forest landscape as this information is critical to many applications such as emergency response and decision support for fire suppression, prescribed burning, fire prevention education and fighting training. We review the progress in fire spread simulation and virtual forest modeling, and present a 3D forest fire spread simulation...
Wildfire spread is a complicated phenomenon that affected by many factors, such as terrain, vegetation, and weather conditions. This paper presents a wildfire-spread simulation and visualization method. A simulation system was developed based on OSG(Open Scene Graph) and FARSITE (Fire Area Simulator). The system can visualize a realistic 3D wildfire scenario considering the influence factors. Wildfire...
To overcome the limitations for traditional manual meter-reading and poor suitability of modern meter-reading system regarding electric energy metering, a portable automatic ammeter reading system is put forward based on digit recognition algorithm. With the numerical recognition of images from dial plate as its core, this system accomplish the recognition of user code and electricity numbers before...
