The computation of semantic similarity of terminologies in gene ontology is an important application of gene ontology. Moreover, it is an important approach for biologists to deal with the semantic heterogeneity of biological data sets. Existing approaches in this field are based on semantic distance or information quantity. The author proposes a comprehensive approach where the similarity is first computed on the terminological level, inducing density-constraining and depth-constraining variables based on the microscopic structure (density and depth of the nodes) of the gene ontology nodes, then based on node properties and inference-based instances, the comprehensive semantic similarity is computed. From the result of comparison with the Resnik method, the ZZL method, Lin method and Combine method, the above proposed method proves to be favorable.

At present, the use of dynamic programming method to solve the problem of the single-type missile fire distribution has been more mature. With the development of the diversification of missile types, the problem of the multi-type missile fire distribution is in urgent need for solution. Based on dynamic programming, the optimization model of the fire distribution of two types of missiles, the solution method of the model, and the example are given in this paper. And the fire distribution of more than two types of missiles is discussed in the end.

The port is the hinge of sea transportation, and it is also an important target which would be attacked by the both sides in future campaign. At present, most research models on the port capacity are only about the port taken as a berth service organization and the arrival ship as a queuing customer, but few about the full logistics process of the arrival ship loading and unloading cargoes at the port. First, based on Petri nets the model of the port's full logistics process is built; Secondly, full logistics process of the port (commercial port) is taken as a whole study object to be simulated. Finally, the flowchart and simulation conclusion is given.

When evaluating the performance of a batch of Inertial Measurement Unit (IMU) and encountering abnormal samples, the current method was uneasy to retain the stabilization of evaluating results. In the case, a method based on median theory is presented in the paper. Theory analysis and example results show that the median method overcomes the shortages of the current method effectively. Additionally, the accuracy and reliability of evaluating results can also be guaranteed by using the two methods synthetically.
