We theoretically and experimentally investigate circular plasmonic disc nanoantennas enhanced in their performance by a surrounding Bragg grating ring structure. PEEM investigations are demonstrated to provide unprecedented insights into the field localization and enhancement.
Versatile Distribution is usually used in component failure distribution fitting. It can characterize the Function changes accurately by changing its parameters. This paper first conducts a brief analysis of protective relay failure characteristics. Then based on Versatile Distribution, an aging failure rate estimation method of relay protection device with nonlinear programming is proposed. Then...
Wireless sensor networks are often deployed for tracking moving objects. Many tracking algorithms have been proposed with two general assumptions: the preset fingerprints(prior landmark or context information) and an interference-free environment. These algorithms, however, cannot be used for on-demand deployment where finger-prints are unavailable and would perform poorly in interference-rich environments...
In the background of economic globalization, the market competition becomes increasingly fierce. More and more high-tech enterprises begin to update organization and management model and use the type of team work. Due to the different backgrounds of team members, team conflicts have become a major problem puzzling the enterprises. Based on this, the study regards high-tech enterprises as research...
In wireless sensor networks, this paper puts forward a distributed fault detection algorithm to solve the node failure problems. It takes into account the spatial correlation of network node, based on the way of weighted distance, compares its own reading with the weighted value to judge the fault node. Finally, the feasibility and effectiveness of the algorithm is demonstrated via computer simulation...
Based on K-Means algorithm and agglomerative hierarchical clustering algorithm, improvement was made regarding the use of clustering algorithm in the application of text mining. It was verified that the accuracy and efficiency of hot topic detection had been enhanced via vector representation of the text, text similarity calculation, and implementation of clustering algorithm.
With the gradual expansion scale of mobile intelligent terminals and the popularity of social networks, information exchange among mobile users shows the social characteristics. This article takes the same interest information among users to define the social relationship metrics such as contact frequency, contact strength and contact regularity etc. A ranking information forwarding algorithm with...
This paper presents a new design method to improve the performance of CIC filter. After the CIC filter cascaded the compensation filter which has inversed magnitude response to CIC filter was proposed, which improved the pass band and the transition band features of the CIC filter and improved the performance of CIC filter. The decimation factor of the CIC filter is M and stage of it is N. The new...
This paper describes the OFDM technology and its applications. Analysis the causes of PAPR in OFDM system, then the number of different sub-carrier under the conditions were simulated CCDF. Using clipping and filtering algorithm effectively reduces the PAPR of OFDM system, and the effect of reducing the PAPR and BER performance of the system were both made theoretical analysis and simulation. By analyzing...
The objective of this study is to analyze the differences between split post-crown rehabilitation system and split post-core-crown rehabilitation system. Stress distributions of the models in different rehabilitation systems could be obtained through reverse engineering, virtual surgery and three-dimensional finite element analysis. Results showed that strong stress concentration appeared at the contact...
The paper analyze the mathematical model of ship steering system and propose a control algorithm of ship steering system based on iterative learning control. In the article, we describe the principle of iterative learning control, analyze the dynamic equation of ship steering system, and demonstrate the convergence of corresponding updating law. The numerical simulations show that iterative learning...
In this paper, elements of security risks and their relationships in information systems are analyzed, and the three-dimensional model of security management and control system ITG-PRS-ISMCS and the improved management process ITG-PRS-PDCA of information systems based on risk control are built from such views as process controlling, resource protecting, and realization of security objectives according...
The 21st century is marked with a new trend towards new technological innovation, cross-cultural communication, globalization of economy, economization of knowledge and internationalized economic and commercial rules, which presents new challenges to the economic and social development of China and her enterprises' participation in the domestic and foreign markets. Intellectual property economy has...
Along with knowledge-intensive and globalization of economy, the intellectual property rights become the competitive advantage core of one nation as well as an area. The Intellectual Property Services are now at an unprecedented breadth and depth of impact on the world's politics, economy, military and culture, as well as human society in all aspects of life. Based on relative studies and intellectual...
Learning Bayesian network parameters is the basis for Bayesian network to solve practical problems. However, the current methods of learning Bayesian network parameters have problems of large computation capacity, slow rate and so on, especially, more severe in learning parameter with missing data. Therefore, we propose a learning algorithm based on iterative learning control, describe the principle...
