Abstract：On the basis of the basic principles of weighted fusion, Kalman filtering and BP neural networks, the basic principles of information fusion methods used in integrated navigation systems are expounded. Through the analysis of the basic principles, the association of information fusion methods commonly used in integrated navigation systems and information failure modes is obtained: the information fault mode of weighted fusion method The model is closely related to the specific weight allocation method, which depends on the fault mode of the sensor or sub-system in which the weight is dominant; the information fault mode of the Kalman filtering information fusion method is a continuous mutation fault corresponding to the nonlinear time interval of the system; the information fault mode of the BP neural network method is gradual with time. The information failure mode of the BP neural network method is a slowly varying fault that gradually accumulates over time. Starting from the complexity associated with the information fusion method and the information failure mode, it is pointed out that in order to systematically express the relationship between the information fusion method and the information failure mode, further research can be carried out.

To address the problems of fusion efficiency, detection rate (DR), and false detection rate (FDR) that are associated with existing information fusion methods, a multisource information fusion method featuring dynamic evidence combination based on layer clustering and improved evidence theory is proposed in this study. First, the original alerts are hierarchically clustered and conflicting evidence is eliminated. Then, dynamic evidence combination is applied to fuse the condensed alerts, thereby improving the efficiency and accuracy of the fusion. The experimental results show that the proposed method is superior to current fusion methods in terms of fusion efficiency, DR, and FDR.

In order to solve the problems of heavy computational load and poor real time of the information fusion method based on the federated Kalman filter (FKF), a novel information fusion method based on the complementary filter is proposed for strapdown inertial navigation (SINS)/celestial navigation system (CNS)/global positioning system (GPS) integrated navigation system of an aerospace plane. The complementary filters are designed to achieve the estimations of attitude, velocity, and position in the SINS/CNS/GPS integrated navigation system, respectively. The simulation results show that the proposed information fusion method can effectively realize SINS/CNS/GPS information fusion. Compared with FKF, the method based on complementary filter (CF) has the advantages of simplicity, small calculation, good real-time performance, good stability, no need for initial alignment, fast convergence, etc. Furthermore, the computational efficiency of CF is increased by 94.81%. Finally, the superiority of the proposed CF-based method is verified by both the semi-physical simulation and real-time system experiment.

Representation Method

During fault diagnostics of mechanical systems, information fusion methods were widely used to improve the reliability. However, diagnostic information comes from all life cycle of a mechanical device and they are always heterogeneous. Whereas heterogeneous information is difficult to be interconnecting, intercommunicating and inter-operating, so how to represent heterogeneous information is a key problem in integrated diagnostics. In this paper, a novel ontology-based representation method of heterogeneous diagnostic information is presented in detail. Firstly it introduces basic principles of ontology-based modeling. Then three methods of ontology-based information modeling are studied respectively. In the end an example of ontology-based modeling for a diesel engine is given.

ABSTRACTRevolutionary struggle in order to compete for the independence of Indonesia has been a source of inspiration Indonesian artists, including Bambang Soelarto who wrote drama Domba-domba Re- volusi (DDR). DDR studied drama is quite interesting because it tries to criticize the freedom fight- ers. This study aims to: first to know the theme and the problem plays DDR; second to determine the relationship of the socio - historical struggle in 1948 with the sociological elements of drama DDR themes and issues. This study uses sociological theory of art. The basic principles of the sociology of art is the fact that the creation of works of art influenced by the historical social conditions where the work was created. Research using content analysis of Krippendorf, the methods used to examine the symbolic phenomena with the aim to explore and express the observed phenomenon which is the content, meaning, and an essential element of the literary work. Based results of this research is that Bambang Soelarto as the author tries to capture di?erence between fighters during the struggle for the political aspirations for 1948 are expressed in a work of drama. Historical events inspired the creation of drama DDR. Soelarto want to respond to the political aspirations of the di?erence between historical figures and wanted to provide an assessment and outlook through DDR.Keywords: themes, drama, sociology of art, social historical ABSTRAKRevolusi perjuangan dalam rangka memperebutkan kemerdekaan Indonesia telah men- jadi sumber inspirasi para seniman Indonesia, termasuk Bambang Soelarto yang menulis drama Domba-domba Revolusi (DDR). Drama DDR cukup menarik diteliti karena mencoba mengkritisi para pejuang kemerdekaan. Penelitian ini bertujuan untuk: pertama, mengeta- hui tema dan permasalah drama DDR; kedua, mengetahui hubungan kondisi sosio-histo- ris perjuangan pada tahun 1948 dengan unsur-unsur sosiologis terimplisir pada unsur tema dan masalah drama DDR. Penelitian ini menggunakan teori sosiologi seni. Prinsip dasar dari sosiologi seni adalah adanya fakta bahwa penciptaan karya seni dipengaruhi oleh kon- disi sosial historis tempat karya itu diciptakan. Penelitian ini menggunakan metode con- tent analysis dari Krippendorf, yakni metode yang dipergunakan untuk meneliti fenome- na-fenomena simbolik dengan tujuan untuk menggali dan mengungkapkan fenomena yang teramati yang merupakan isi, makna, dan unsur esensial karya sastra. Berdasarkan hasil penelitian dapat diketahui bahwa Bambang Soelarto sebagai penulis mencoba un- tuk menangkap perbedaan antara pejuang aspirasi politik selama perjuangan tahun 1948 untuk diekspresikan dalam sebuah karya drama. Peristiwa sejarah mengilhami penciptaan drama DDR. Soelarto ingin menanggapi aspirasi politik perbedaan antara tokoh-tokoh se- jarah dan ingin memberikan penilaian dan pandangan pandangannnya melalui DDR.Kata kunci: tema, drama, sosiologi seni, sosial historis
