With the growing of elderly population in china, the problem of old people supporting has been concerned about the real estate sector, which have invested, the Estate for the aged came into being. In this article, it take the Operating mode as the entry point and combined with China's national conditions to proposing that china should use the mixed operate mode. Hereinafter we referred to operating...
Along with our country market economy system perfect cost investment system, price system also constantly optimize the project construction cost, construction project becomes more and more important. This paper from the project cost management objectives, significance and key control, research the development condition.
Existing research on high-availability(HA) of data stream systems mainly focused on restoring single node failure effectively, replacing the failed nodes with redundant backups to make the system go well. However, how to improve availability of DDSMS from the perspective of operator redundancy and multiple failures are paid less attention. In this paper, an improved HA mechanism based on operator...
Job information is the basic resource for employment, job information acquisition ability directly affects the employment of new generation migrant workers. This paper analyzed job information acquisition ability through normal channels of new generation migrant workers from different types of the cities from both supply and demand aspects, used Demand-Identified Bivariate Probit Model to analyze...
Based on 1,130 valid questionnaires with new employees, this paper explores the mediating effect of person-organization fit between organizational socialization and work performance of new employees from the perspective of interaction between an organization and its new employees through factor analysis, descriptive statistics, correlation analysis, second-order confirmatory factor analysis, multiple...
Image segmentation is an important technology for image processing. Many segmentation methods have been brought forward for image segmentation, among these methods thresholding is the simplest and effective method in image segmentation. In general, the thresholding method based on two-dimensional histogram can provide better results than that of one-dimension histogram. However, for more accurate...
In the process of generating a surface model from point cloud data, a segmentation that extracts the edges and partitions the three-dimensional (3D) point data is necessary and plays an important role in fitting surface patches and applying the scan data to the manufacturing process. However, it is always difficult to extract the exact edge points because the scan data consist of discrete points and...
For the bus has serious impact on the intersection running effective, the paper gives a new passenger car equivalent method for the bus according to the bus's time-space characteristics. When the bus arrives and departs the intersection without stopping, the passenger car equivalent is set as the section of highway, when the bus passes the intersection experiencing stop, the passenger car equivalent...
This study applies a hybrid MCDM model for risk evaluation in Mobile Commerce development. First, the risk in MC development is formulated by the combined use of the MCDM (multi-criteria decision making) approach and a proposed five-step hybrid process, which incorporates the technique of ANP (analytic network process) and TOPSIS (technique for order performance by similarity to idea solution). The...
This paper studies technologies for control and scheduling co-design. The influence of sampling period to networked control system is discussed. Based on control performance optimization and network scheduling condition, considering system control and network scheduling, an optimized model and optimal sampling period selection algorithm are proposed. Simulation results shows that the algorithm satisfies...
This paper proposes a design scheme of a sensor network based on M-Bus, according to the communication protocol and characteristics of M-Bus, and developed the special master/slave interface circuit of M-Bus. The sensor network is intrinsically safe, low power consumption, bus-powered, plug and play, and easy for system expansion. The sensor network is suitable for monitoring system which have numerous...
Based on the shortcomings of traditional state detection firewall and TCP state detection related work, TCP state detection system is designed based on the integrated circuit, compared with single-state detection process of the traditional state detection system, low efficiency of the connection timeout management and the package status information lookup, solving strategies of some key technology...
At present, with the rapid development of college student organizations, and take improving the quality and capacity of students as the purpose, it is playing an increasingly important role of improving the overall quality of the students. This paper defines the college student organization and the overall quality of the college students, and analyses the link between the two, On this basis of the...
In response to the urgent demand for talents brought caused by China's rapid economic development, combined with the present situation of higher education development and based on the questionnaires answered by freshmen, we chose classroom-based teaching model as a breakthrough in order to do research of and attempt reforms on current teaching model and consequently initially construct a teaching...
Tikhonov regularization is an effective way in particles size inversion of dynamic light scattering (DLS). Regularization parameter choice is the key in this approach. In order to obtain the optimal regularization parameter, according to the Morozov discrepancy principle, an regularization inversion method based on genetic algorithms (GA)is proposed. It optimizes the regularization parameter within...
This paper first discusses what e-learning and integrated e-learning is, then compares the differences between traditional learning, e-learning and integrated e-learning. Conclusion is made by the comparison that integrated e-learning has more advantages over the other two. At the same time, this paper probes into the characteristics and infrastructure of integrated e-learning and the probability...
Image segmentation is the most significant step in image analysis and is a long-term difficult problem, which hasn't been fully solved. Many segmentation methods have been brought forward to deal with image segmentation, among these methods thresholding is the simple and important method in image segmentation. In practical work, 2-dimension (2D) entropy method is often used. It segments images by...
To solve the limitation of interfaces for more function, this article introduces the communication between two single-chips (89C51) to increase interfaces. On account of leaving serial port, three interfaces are defined. The first is to send data, the second is to receive data, and the third is clock. Hardware circuit design is accomplished by Proteus. Simulation for the communication between single-chips...
More and more smart systems have been used in modern household. This article mainly introduces the smart household control system realization procedure based on DTMF remote transmission. The system used AVR SCM to dispose and exchange information. We realized household appliances remote control by communication through mobile telephone and GSM card of the system host computer TC35i by DTMF signals...
With the rapid development of information technology, computer technology has been getting more widely used in daily life, thus, it is necessary for each university graduates grasp basic technical skills of computers. However, usually a teacher will be responsible for teaching many college students basic computer courses, so it is difficult to ensure the quality of the teaching with the enlarged students'...
