Without the applicable methods of forecasting the outbreak of debris flows in a wide area as well as long time, wireless sensor networks (WSN) of monitoring debris flow are essential for protecting safety and property of human. In nowadays, a common and key consideration of the network would be the energy efficiency, since both of the soil moisture (SM) sensor and the radio are power-hungry, meanwhile,...
Combining a nonlinear damage accumulation model, a probabilistic S-N curve and one-to-one probability density functions transformation technique, a general probabilistic methodology for modeling damage accumulation is developed to analyze the fatigue reliability in this paper. The damage accumulation is characterized as a distribution in a general degradation path, which captures a nonlinear damage...
Uncertainty exists in the engineering practices widely. Since a multidimensional integration problem should be dealt with during the process of reliability-based analysis and design, it is the key problem to develop new method to improve the efficiency and accuracy for the reliability-based analysis and design in the complex systems. Hence a new method is proposed, and the procedure of the proposed...
This paper places the competence of Colleges and Universities (CAU) on the foundation of the uncertain characteristic analysis in scale and level of running a school, and describes the attainability of the education indexes for formation of the competence and the controllability of management behaviors. This paper also puts forward the inversion orientation theory for the uncertainty analysis of education...
This paper puts forward the new concept of trusted computing and discusses the characteristics of non-optimum in computer computing system based on the trend of the research in information security. It establishes the learning approach of sub-optimum for information system. Research show, sub-optimum learning is very important tool in development trusted computing, system (TCS). Through compared the...
The article discusses the characteristics of mobile and embedded database as well as its synchronization realization on mobile terminal along with practical application. The article further provides several methods to improve the data accessing rate, efficiency, stability, maintainability and uniformity of the database, including multithread technology, three-layer duplication/buffer architecture,...
This article discussed many problems which exist in the process of realizing GIS datapsilas synchronization based on the characteristics of GIS spatio-temporal data and mobile database, such as how to improve the efficiency of data visiting and updating and guaranteeing data transmissionpsilas reliability and uniformity and so on, proposed the multithread technology, three-layer duplication/buffer...
