The current paper addresses the warfare command decision-making problem for winning when the total combats capability of the attacking side is not superior to that of the defending side. For this problem, the corresponding warfare command stratagems, which can transform the battlefield situation, are proposed and analyzed quantitatively by considering the influence of the warfare information factor. The application examples in military conflicts show the feasibility and effectiveness of the proposed model and the warfare command stratagems for winning. The research results may provide a theoretical reference for warfare command decision making.展开更多

To solve this problem, an improved Kullback-Leibler divergence sparse autoencoder （KL-SAE） is proposed in this paper, which can be applied to battle damage assessment （BDA）. This method can select automatically the hidden layer feature which contributes most to data reconstruction, and abandon the hidden layer feature which contributes least. Therefore, the structure of the network can be modified. In addition, the method can select automatically hidden layer feature without loss of the network prediction accuracy and increase the computation speed. Experiments on University ofCalifomia-Irvine （UCI） data sets and BDA for battle damage data demonstrate that the method outperforms other reference data-driven methods. The following results can be found from this paper. First, the improved KL-SAE regression network can guarantee the prediction accuracy and increase the speed of training networks and prediction. Second, the proposed network can select automatically hidden layer effective feature and modify the structure of the network by optimizing the nodes number of the hidden layer.展开更多

Since reform and opening up, in particular, China has planned for and organized development-oriented poverty reduction practices on a broad scale with remarkable achievements and blazed a new path of development-oriented poverty reduction with Chinese characteristics. This path is both an essential component of Chinese socialism and a result of the CPC’s ideological improvement on poverty reduction. Since the 18 th CPC National Congress in 2012, the whole Party, country, and society have been called upon to fight the battle against poverty on a full-scale under the guidance of General Secretary Xi Jinping’s important statements on poverty reduction, unveiling a new stage for China’s development-oriented poverty reduction in the new era. China’s unprecedented poverty reduction achievements have enriched the path of poverty reduction with Chinese characteristics. Xi Jinping’s insightful and coherent statements on poverty reduction represent the latest results of Marxist anti-poverty theories and comprise an essential part of Xi Jinping Thought on Socialism with Chinese Characteristics for the New Era. His guidelines are the basis for the brilliant achievements of China’s poverty reduction endeavors, and will contribute Chinese experience and wisdom to global poverty governance.展开更多

This has been called "Interventionalogy", "interventional medicine(IM)", or simply Intervention by our team,and "Interventional Radiology" is used no more. It has even been given the name "Third clinical Medicine" by us. Chinese intervention has established an independent association for interventional doctors, as well as independent interventional societies in many provinces. The national interventional society will likely be set up at some point in time. Chinese interve ntion has set up their own clinical wards, with much attention paid to a clinical, professional, and normalized direction for development, and established special nursing units. According to us, turf battle is meaningless. "The Third clinical Medicine" belongs to all human beings. It could also be predicted that interventional history will follow the same evolutionary rule as other disciplines, i.e., "long divided, must unite; long united, must divide".展开更多

The variation rules of the residual velocity and residual mass of fragments, chock mass and crevasse shape are obtained when the fragment penetrates target board with different incidence velocities and attack angles. Corresponding fitting computation formulas are concluded from the above calculating data. The conclusions are helpful to analyzing the destructivity of fragment and protective ability of aircraft structure. In addition, they can guide the research for battle damage mode and assessment effectively.展开更多

This paper introduces a critical relative distance prediction method of aircraft wing damage based on the back-propagation artificial neural network(BP-ANN), which is trained by finite element simulation results. Moreover, the finite element method(FEM) for wing blast damage simulation has been validated by ground explosion tests and further used for damage mode determination and damage characteristics analysis. The analysis results indicate that the wing is more likely to be damaged when the root is struck from vertical directions than others for a small charge. With the increase of TNT equivalent charge, the main damage mode of the wing gradually changes from the local skin tearing to overall structural deformation and the overpressure threshold of wing damage decreases rapidly. Compared to the FEM-based damage assessment, the BP-ANN-based method can predict the wing damage under a random blast wave with an average relative error of 4.78%. The proposed method and conclusions can be used as a reference for damage assessment under blast wave and low-vulnerability design of aircraft structures.展开更多

In last five decades, the development of modern armies has taken place around Colonel John Boyd’s theory of OODA loop that deals with information superiority. Building a robust, mobile and capable network that could provide for novel appliances and information superiority is the main challenge which modernizers are facing. Network, suitable for future combat operations, and able to transport a vast amount of information on a battlefield, is expensive to build. Every mistake in design and the need to correct those mistakes could halt development in an army for years. Therefore, system dependability analysis during system design phase is needed. In this report, the concept of a future Battle Network System is described. The Report evaluates operational environment of BNS and possible failure reasons of the service, and illustrates the change in BNS Quality of Service due to probable transport layer errors. This paper describes the method of testing the concept of proposed network systems on the drawing board, and emphasizes design points for a new system. Nevertheless, the proposed method is by no means conclusive. Rather, it describes an engineering approach to define the main problems while creating MANET-based networking systems.展开更多
