Notice of RetractionResearch on fuzzy comprehensive assessment for fire safety of regional buildings
The primary mission of fire safety assessment is seeks the change rule of system security, and entrusts with the certain quantity of the concept. Then according to the security condition and the degree of hazard of the system, take the essential measure to achieve the anticipated security goal. According to the characteristic, the origin of the buildings fire, the paper adopted the fire safety assessment method to research the preventing and controlling on buildings fire. The paper briefly introduced the fire safety assessment principle, the theory and the method, and adopted the fuzzy synthesis assessment method as the reasonable method for the fire safety evaluation of buildings. A fire safety assessment index system was founded firstly. Then, the calculation methods for the weight of evaluation indexes and fuzzy calculation were described. Finally, a comprehensive regional buildings fire evaluation and emergency response system was illustrated.
Application of Computational Simulation in Fire Science and Engineering Research
Computational simulation, especially field modeling, is highly developed in recent years. While it has been widely used in many fundamental research and engineering fields, few were applied to aspects of fire science and engineering research. In this paper, the developments and applications of computational simulation for fire dynamics arc firstly reviewed. The basic principles of large eddy simulation are described in detail, which involves turbulence modeling, combustion modeling, and thermal radiation modeling. An example of numerical experimental study of fire dynamics process for oil tank fire with large eddy simulation technology is provided and some fire provisions are approved with respect to the results. 
From the case, it is shown that field modeling has an extensive application future in fire safety science and engineering research. And it will become an effective means in fire management, fire risk evaluation, decision -making and supporting plan for severe disasters and so on.
Investigation of International Standard, International Electrotechnical Commission, IEC 62305 and Indian Standard IS 2309 in positioning the Air Terminals (ATs)
From 18th Century onwards, many scientists and researchers across the globe have conducted experiments and researches related to the subject called Lightning and as a result they have acquired success in protecting the structures against lightning strokes to a great extent. However, the science behind lightning has not been completely discovered and therefore any design of lightning protection scheme can’t be certified as cent percent safe. Here in this paper, a cuboid equivalent to a rectangular industrial building has been taken into consideration. Lightning Protection Scheme for the same has been designed in two ways: i) based on the Protective Angle Method and Rolling Sphere Method as per International Standard IEC 62305 and ii) based on the Protective Angle Method as per Indian Standard IS 2309. This paper mainly focuses on the comparison of those two designs which ultimately discloses the difference in safety level that we are having by adopting a particular standard.
