of Japan are mostly concentrated in Kyoto, Nara and Tokyo. Particularly in Kyoto, cultural heritage places are scattered with high density in the relatively small basin, which is incomparable with any other city and/or town. Case studies have been conducted to develop a protection system from post-earthquake fire for the oldest wooden temple structure in the Kyoto basin, making use of a water c...

Landscape corridors are commonly used to mitigate negative effects of habitat fragmentation, but concerns persist that they may facilitate the spread of invasive species. In a replicated landscape experiment of open habitat, we measured effects of corridors on the invasive fire ant, Solenopsis invicta, and native ants. Fire ants have two social forms: polygyne, which tend to disperse poorly but...

aims: the occurrence of fire in residential buildings , commercial complexes and large and small industries cause physical, environmental and financial damages to many different communities. fire safety in hospitals is sensitive and it is believed that the society takes the responsibility to care sick people . the goal of this study was to use fire risk assessment method for engineering (frame)...

Lightning fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition on lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how these biotic and abiotic components contribute to ecosystem dynamics in the mixedwood boreal forest. We...

As a suitable candidate for the next halon alternative gaseous fire-extinguishing agent, it is very meaningful to investigate how to improve the fire-extinguishing capacity of hot aerosol fire extinguishing agents for local fires. When fire breaks out, the actual fire location is unpredictable, and the extinguishing efficiency of hot aerosol extinguishing agent will be observably affected by th...

Market-driven methods are the applications of basic free market economy principles to multiagent planning tasks. They take advantage of the communication among the team members for maximizing the overall utility of a team of agents, one example of which is the rescue agents competing in the RoboCup Rescue Simulation League. In this paper, a modified market-driven algorithm and its integration t...

HISTORIC[1] Halogenated compounds have been employed as fire extinguishing agents since the early 1900s, when handheld extinguishers containing carbon tetrachloride (CCl4) were first introduced. In the late 1920s, methyl bromide (CH3Br) was found to be more effective than carbon tetrachloride, and was widely used as a fire extinguishing agent by the British in the late 1930s for aircraft protec...

Aerosol fire extinguishing agents have been recognized as an effective replacement of Halon. The uniform diffusion time and the effective concentration of the aerosol fire extinguishing agent are important parameters for putting out a fire. In this work, the effective concentration is derived based on the diffusion equation, and its variation with changing diffusion coefficient and diffusion ti...
