1.1 The methane thermophysical property tables are for use in the calculation of the pressure-volume-temperature (PVT), thermodynamic and transport properties of methane for process design and operations. Tables are provided for gaseous and liquid methane at temperatures between 90 and 600 K at p...

1.1 This method covers the determination of minimum energy for ignition (initiation of deflagration) and associated flat-plate ignition quenching distances. The complete description is specific to alkane or alkene fuels admixed with air at normal ambient temperature and pressure. This met...

A method to model and analyze the hybrid systems is presented. The time to. be considered in the plant is taken as an explicit parameter through the constrained predicated net (CPN). The CPN' s basic structure is a Petri net with predicated transition. All components of the net are expressed by anno...

Since the simulation underwater acoustic signal is used in the semi-object simulation experiment of underwater weapons, it has great impression upon simulation fidelity. It is asked that whether simulation signals can replace the real signal effectually. Considering the randomness of signals, the in...

Traditional data envelopment analysis (DEA) theory assumes that decision variables are regarded as inputs or outputs, and no variable can play the roles of both an input and an output at the same time. In fact, there exist some variables that work as inputs and outputs simultaneously and are called ...
