The solution to the problem of finding the reaction kinetic realization of a given system obeying the mass action law containing the minimal/maximal number of reactions and complexes is shown in this paper. The proposed methods are based on Mixed Integer Linear Programming where the mass action kinetics is encoded into the linear constraints. Although the problems are NP-hard in the current setting, the developed algorithms give a usable answer to some of the questions first raised in [1].
Nowadays, decision tree is widely used as one of the most powerful tools in data mining. However, to construct an optimization decision tree is a complete NP problem. So a new method about how to construct decision tr...

In order to solve the problem that mechanical pointer type flowmeter cannot be calibrated automatically, based on the photoelectric conversion principle, a non-contact meter pointer automatic identification sensor was designed. The signal acquisition hardware and software of the pointer identification sensor were designed also. Two flowmeters can be calibrated at the same time. It was shown by the result of experiments that automatic recognition of meter pointer, automatic signal acquisition and processing were achieved. It meets the industrial field demand of mechanical pointer type flowmeter automatic calibration.

In this paper, the evaluation methods of flow standard facility in every regulations were compared and analyzed. Analysis of the two performance parameters of the flow stability within cumulative time and the flow stability between cumulative time. From the two angles of the structure of turbine flow meter itself and the calculation formula of the stability parameter, the selection principle of the stability parameter is determined. The flow stability between cumulative time is selected as the main parameter, and the flow stability within cumulative time as reference. And the results of flow stability test between the method of turbine flow meter and the weighing method were compared. The results show that the method of turbine flow meter can also be an accurate method for testing the flow stability of flow standard facility.
