This paper briefly introduces the concept, origin, fault tree analysis method and simple calculation formula, based on the fault tree analysis and understanding, and its calculation method and idea was applied to specific instances of fire control design, for a combustible gas cylinders yard fire control design of the status quo, combustible gas cylinder storage area for the storage, storage containers,...
As the viewing range of the existing fire detection devices is normally short, and directional detection of the flame can not be achieved, it can not be used in many cases. An optical design and implementation based on flame pyroelectric sensor are present in this paper. Two types of directional flame detection are provided. One is to achieve plane-type directional detection, and the other is to achieve...
An algorithm named PTBBWD is presented to detect worms. It is process traffic behavior based and has considered three important behaviors: total amount of source ports in wormlike traffic, changing frequency of source ports in wormlike process traffic and the wormlike traffic proportion of the total process traffic. Unlike similar work before, PTBBWD checks the frequency and the total amount of source...
