The material and structural thermal deformation characteristics of a steel stiffened panel under various fire-extinguishing methods were investigated experimentally. Propane gas was used to generate jet fires for panels widely as offshore installation structures. the initial imperfection (initial deflection residual stress) occurring during fabrication measured analyzed before after fire experi...

It is shown that the evolution of autonomous mobile fire-extinguishing means includes four stages, in which these are divided into portable, wearable, and mobile. All fire extinguishing united by presence a human operator. Portable equipment characterized small weight, does not exceed 20 kilograms. has greater mass (up to 30 kilograms) and, as result, longer duration agent supply 75 seconds). S...

Forest fires are an important problem for many countries. Prevention, surveillance and extinguishing tasks are costly and sometimes risky. This paper focuses on the surveillance of the fire embers once the fire is extinguished. This is a post-fire task which requires an important amount of terrestrial resources, especially if the weather conditions may provoke the re-ignition of the fire. We pr...

Woodland fires are a major issue worldwide. The aviation method of extinguishing forest is one the main ones. However, use latter carried out according to results experiments, bench or flight tests in absence models that adequately describe mechanisms for suppressing combustion combustible materials with specific fire compositions (solutions, emulsions suspensions). Therefore, task studying eva...

Landslide trails are important elements of landslide inventory maps, providing valuable information for risk and hazard assessment. Compared with traditional manual mapping, skeletonization methods offer a more cost-efficient way to map trails, by automatically generating centerlines from polygons. However, challenge existing is that expert knowledge intervention required obtain branchless skel...
