The increased amount of redundant units means improvement of task reliability, however, the additional units and corresponding vote devices request more logistics, which results in decline of basic reliability. In this paper, we design and make analysis and comparison of multiple redundant structures in two ways of task reliability and basic reliability. This paper provides theoretical reference for...
Lots of scholars depend on the Internet for rapid access to the other scholar's research information and build cooperative relationship. But current systems for finding another scholar who share the same research field or interests do not adequately satisfy the need of scholars; moreover the process of seeking is time-consuming and difficult. In this paper, we use the data from scholar's profile in...
Collaboration networks are among some of the social networks and offer us the opportunity to study the structure underlying the networks. In this paper, we utilize the social network analysis (SNA) framework to understand what characterizes the social structure of the CSCWD conference's paper co-authorship network. It can potentially provide us with an understanding of the individuals and the network...
The paper propose the fuzzy control with recurrent fuzzy basis function neural network (RFBFNN) height control of magnetic bearing system. The magnetic bearing is a very unstable nonlinear system. Fuzzy control need not accurate mathematical model to have good output response for nonlinear systems. However, the fuzzy control cannot guarantee the stability and convergence. Neural networks also need...
Stream Reassembly is an indispensable function of Deep Packet Inspection, which is an critical element of Network Intrusion System. However, since it need to heavily move packet payload from one block of memory to another block of memory, Stream Reassembly has a serious memory performance issue. In this paper, in order to improve the Stream Reassembly performance, a Stream Reassembly Card (SRC) is...
In order to improve generation performance of wind and solar power, the integrated power generation of wind, photovoltaic (PV) and energy storage is a focus in the study. In this paper, the integrated generation electromechanical model of wind-farm, PV station and energy storage station is achieved so as to establish the foundation of its connected-grid simulation and analysis. First, the models at...
This paper presents a model of the lung mechanics which simulates the pulmonary alveolar ventilation. The gas laws and pulmonary compliance theories are used to establish the mathematical model of the ventilation. Our results show that the lung can be simulated by the model. Our lung model controls respiratory function through the control of internal pressure.
Low efficiency existing in the current approaches for large scale document similarity computation, to make an improvement we pinpointed a new approach based on cloud computing platform in this paper. The approach carried out document similarity computation based on traditional vector model space as well as applied MapReduce computation model to realize the parallelization of distributed inverted index...
Wind power is a random and intermittent energy source, wind farm output prediction accuracy is not yet able to meet the purpose of engineering applications. In recent years, with the large-scale wind power integration, because of the randomness and volatility of wind power output, the active power of system node fluctuates severely, which greatly increases the difficulties in controlling the grid...

This article analyzes the factors of affecting an innovative culture, puts forward the main factors of innovative culture, government, education, enterprise, financial and intermediary institutes. Moreover, finds connections and...
The development of the Internet and E-commerce makes the enterprises' competition beyond the time-space constraints. The rules of traditional market competition also have been changed. Soft power has become as important as hard power in the enterprises' development. A clear exposition of the relationship between soft power and hard power is very important for acquiring sustainable competitive advantage...
Through applying spatial statistical analysis, Geographical Weighted Regression (GWR) model and GIS technology, this study aims at finding the relationship between the effects of various factors and spatial distribution of residential house price. The traditional regression models are reviewed firstly, the model without the consideration of spatial characteristics cannot reach very nice precision...
A new slope protection technology — geocell Bioengineering protection technology was brought forward. In this paper, combining with the engineering practices, the design and compute methods of geocell flexible retaining wall were given and the effect of its application was studied. According to the in-situ measured data of the earth pressure and the deformation of retaining wall, the part of the earth...
Regular expression matching engine is a crucial infrastructure which is widely used in network security systems, like IDS. We propose Gregex, a Graphics Processing Unit (GPU) based regular expression matching engine for deep packet inspection (DPI). Gregex leverages the computational power and high memory bandwidth of GPUs by storing data in proper GPU memory space and executing massive GPU thread...
This paper is concerned with a study on the feature selection for ranking. Learning to rank is a useful tool for collaborative filtering and many other collaborative systems, which many algorithms have been proposed for dealing this issue. But feature selection methods receive little attention, despite of their importance in collaborative filtering problems: First, recommender systems always have...
This paper redefined the indicators of distribution system reliability analysis, combined the topology and reliability with a new comprehensive index as a reflection of the load point failure rate, and established the artificial neural network classifier. Simulation results show that the method helps to improve the efficiency of distribution network reliability analysis
In view of present situation and technical difficulty of the measure method of Electric fireplace's performance parameter, the modern test and sensor technology are used to design the measure device of Electric fireplace's performance parameter based on VB6.0. The function of measure device is realized by communication between host computer and MCU measure system. The acquisition and treatment of...
Cloud storage services are gaining more and more attention. Surveys suggest that the confidentiality issue is one of the major obstacles for users to use cloud storage services to keep sensitive data. This paper proposes to deploy a Redundant Array of Independent Net-storages (RAIN) for confidentiality control in Cloud Computing. The RAIN approach splits data into segments and distributes segments...
Abstract-Voltage breakdown is one of the most failure mechanisms to IGBT. High voltage can generate high electric field at PN junction of IGBT which withstands high voltage blocking. High electric field can bring avalanche phenomenon if this voltage is too high to make PN junction avalanche breakdown. Avalanche breakdown can make current rising dramatically and destroy the IGBT device lastly. This...
As the electric performances of semiconductor devices are tightly related to their junction temperature, the research on electrical parameters characteristic at different junction temperature is a significant meaning to improve application reliability of IGBT. On the one hand, junction temperature is a key factor to influence electrical parameters of IGBT. On the other hand, electrical parameters...
