In this paper, we construct a class of isospectral vibrating systems from partial explicit spectrum and partial implicit spectrum. It extends the work of P. Lancaster in which the isospectral vibrating systems are constructed only from complete explicit data or complete implicit data. The result can be applied to solve the partial pole assignment problem for the second-order system, such that the...
To overcome the limitations of the traditional threat assessment algorithms, the fuzzy beliefs theory is applied in threat assessment of aerial targets and a multi-attribute threat sorting approach Based on the fuzzy belief is proposed in this paper. Target type, flight height, flight speed, time over the distant boundary, flight course angle and shortcut are selected as the assessment factors. The...
The scale-invariant interest points matching approaches always require a lot of computation and sometimes fail to meet the real-time demands in some application fields. To solve the problem, a new local scale-invariant descriptor based on the image color information is proposed in this paper. The descriptor consists of concentric circle structure which is divided into several subregions. The radiuses...
In order to model beliefs expressed by natural language, the qualitative belief assignment based on the linguistic labels has been presented in the Dezert-Smarandache Theory (DSmT). However, the combination of qualitative beliefs is only based on the equidistant linguistic labels and the calculation of non-equidistant labels is approximate. To solve the fusion problem of qualitative beliefs denoted...
The evidential reasoning theory is often used to process the decision information in decision support. The evidential reasoning is qualified in dealing with uncertain information. However, its combination rules always have some limitations in processing conflict information. In order to solve the conflict problem in the combination of multi-source information, this paper analyzed the conflict solutions...
