With the growth of technology and massive city development, firefighting services have become more challenging to cope with a smart-city concept. One challenges that firefighters are facing is reaching top floors high-raised buildings. Firefighters need heavy oversized pieces equipment reach floors, which they sometimes fail deliver on time due big cities' traffic. The proposed solution this gl...
The dynamic monitoring of fire area is particularly important in the controlling of underground coalfield fire. This paper took the Xinjiang Shuixigou coalfield fire area as an example, through the normalized processing of the multi-temporal thermal infrared images a generalized single-channel algorithm was used to retrieval the surface temperature. Combined with the method of single band optim...
A stereo-vision-based fire detection and suppression robot with an intelligent processing algorithm for use in large spaces is proposed in this chapter. The successive processing steps of our real-time algorithm use the motion segmentation algorithm to register the possible position of a fire flame in a video; the real-time algorithm then analyzes the spectral, spatial, and motion orientation c...
Fire is widely used as a traditional habitat management tool in Scotland, but wildfires pose a significant and growing threat. The financial costs of fighting wildfires are significant and severe wildfires can have substantial environmental impacts. Due to the intermittent occurrence of severe fire seasons, Scotland, and the UK as a whole, remain somewhat unprepared. Scotland currently lacks an...
Time-varying fire-climate relationships may represent an important component of fire-regime variability, relevant for understanding the controls of fire and projecting fire activity under global-change scenarios. We used time-varying statistical models to evaluate if and how fire-climate relationships varied from 1902-2008, in one of the most flammable forested regions of the western U.S.A. Fir...
The Forest Fire Fighting Vehicle (FFFV) is one of the most important pieces equipment in direct firefighting; therefore, its maintenance strategic to guarantee high levels reliability. history interventions essential support increase quality maintenance, namely with regard specificity each equipment, actual operating conditions. In absence previous information, it resort complementary tools tha...
There are reports of gas and oil wells fire due to different accidents. Many different methods are used for fire fighting in gas and oil industry. Traditional fire extinguishing techniques are mostly faced with many problems and are usually time consuming and needs lots of equipments. Besides, they cause damages to facilities, and create health and environmental problems. This article proposes ...
In Southern European countries wildfires are the most natural threat to forests and wooded areas. Over the last decade, public and scientific debates on forest fire management have increased. Helicopters and airtankers are extremely effective fire suppression means, but they are also very expensive. Studies on the improved performance of suppression for the enhancement of firefighting organizat...
The paper deals with a Wireless Sensor Network (WSN) as a reliable solution for capturing the kinematics of a fire front spreading over a fuel bed. To provide reliable information in fire studies and support fire fighting strategies, a Wireless Sensor Network must be able to perform three sequential actions: 1) sensing thermal data in the open as the gas temperature; 2) detecting a fire i.e., t...
