In order to scientifically and effectively allocate university education resources and improve the efficiency of educational resources, we need to evaluate the efficiency of university education. Delphi, AHP and DEA organically combine to establish a combination of university efficiency evaluation model. The model can not only reflect the preferences of decision makers, but also objectively evaluate...
The training level of communication personnel is one of the key factors influencing the combat capability of ships. Aiming at the present situation of communication simulation training system, a integrated training system of ship communication is proposed. Describes the basic functions and composition of the system, and the design of the training scenarios editor is described in detail. In order to...
The efficiency of communication system is the key factor for the operational capability of naval ship. Through analyzing the evaluation index of naval fleet's communication system, a satisfactory-degree based on efficiency evaluation model is founded by applying the grey relational analysis. The steps of the model include gathering index data based on index tree, constituting the reference sequence...
In order to meet the need of terrain model in a ship driving simulation training system, a method of terrain modeling based on S-57 electronic chart is proposed to solve the existing problems. This method integrates three-dimensional terrain data generation technology, GPS positioning technology and GIS geographic information technology, and proposes a method of 3D terrain data generation, radar terrain...
The conductor temperature is an important state indicator of an operation cable,. But direct measurement of the cable conductor temperature is difficult to realize in practice, which is usually obtained by calculation. Presently, thermal circuit method and numerical calculation are adopted to calculate the conductor temperature, however the accuracy of the two methods are greater affected by physical...
In this paper we discussed the method to reduce dimensions of segmentation feature applied to skin erythema image segmentation. Basing on analyzing a lot of erythema images, we proposed a new segmentation feature parameter applied to skin erythema image segmentation. At last, by using the fuzzy-c-means cluster arithmetic, we compared the segmentation speed and segmentation effect of adopting different...
